四、感应圈及设计


1. 感应圈设计展开长度在 1—4.0M 内变动。
2.导磁性差的材料如铜、铝等需感应加热时、感应圈圈数要增多。
3. 感应圈与加热部位耦合间隙在 5—15mm 为宜(加热面积较小时)。
4. 在最大输出位置、电流显示 60KW 100A、工件伸入感应圈内、电流如仍保持不变、但加热效果不好、这种情况说明:负载太轻、或负载与感应圈耦合太差、或感应圈的圈数太少;此时要減小感应圈的尺寸、即減小感应圈与工件之间的间隙;如果间隙已经很小、则要增大感应圈的圈数。
5. 当输出振荡电流不能调至最大、即调节旋钮调至某一位置时、一加负载、电流下降很多甚至自动停机;这说明:负载太重、或负载与感应圈耦合太好、或感应圈的圈数太多;此时只要不会自动停机、都不影响使用、而且此时加热效率也很高;但如果发生自动停机、则要适当增大感应圈的尺寸、即增大感应圈与工件之间的间隙;如果说间隙已经很大、则要減小感应圈的圈数。
6. 对于工作难以置于感应圈内的平面加热、或对非磁性金属材料(如铜、铝)等的加热、可采用不同形状的导磁体(铁氧体磁芯)聚磁、可以大为增加设备的功率输出。
7. 采用厚 1—1.5mm、Φ8 以上圆铜管或方铜管绕制感应圈。
8. 感应圈的引长度允许在 600mm 内变动、推荐 250—500mm 为宜。

IV. Induction loop and design


1. The design expansion length of the induction coil varies within 1-4.0M.
2. When materials with poor magnetic permeability, such as copper and aluminum, need to be heated by induction, the number of induction coils must be increased.
3. The coupling gap between the induction coil and the heating part is preferably 5-15mm (when the heating area is small).
4. At the maximum output position, the current displays 60KW 100A, and the workpiece extends into the induction coil. If the current remains unchanged, but the heating effect is not good, this situation means: the load is too light, or the coupling between the load and the induction coil is too poor. Or the number of turns of the induction coil is too few; at this time, the size of the induction coil should be reduced, that is, the gap between the induction coil and the workpiece should be reduced; if the gap is already small, the number of turns of the induction coil should be increased.
5. When the output oscillation current cannot be adjusted to the maximum, that is, when the adjustment knob is adjusted to a certain position, when a load is added, the current drops a lot or even automatically stops; this means: the load is too heavy, or the coupling between the load and the induction coil is too good, or the induction coil There are too many turns; as long as it does not automatically stop at this time, it does not affect the use, and the heating efficiency is also very high at this time; but if automatic shutdown occurs, the size of the induction coil should be appropriately increased, that is, the induction coil should be increased The gap between the sensor and the workpiece; if the gap is already large, the number of induction coils should be reduced.
6. For planar heating where it is difficult to place the work in the induction coil, or for heating non-magnetic metal materials (such as copper, aluminum), etc., different shapes of magnetic conductors (ferrite cores) can be used to gather magnetism, which can greatly improve the efficiency. Increase the power output of your device.
7. Use round or square copper tubes with a thickness of 1-1.5mm and ⌀8 or more to wind the induction coil.
8. The lead length of the induction coil is allowed to vary within 600mm, and 250—500mm is recommended.

VII. Installation


1. Cooling water connection: Connect the water inlet pipe to the water inlet pipe end at the rear of the equipment, and connect the water outlet pipe to the water outlet pipe end at the rear of the equipment. Make sure the connections are good to prevent water leakage. The water inlet pipe can be connected to a tap or a user-prepared water recycling device. The water inlet should ensure a certain pressure and flow to prevent equipment damage caused by insufficient water pressure and insufficient water flow. The recommended water pressure is 0.05~0.3Mpa and the water flow rate is 20L/MIN. There is a water pressure switch in the equipment to effectively protect the water pressure. If there is no water, it will automatically stop working and make a buzzing sound. In addition, the induction coil of this equipment is soldered. When heated without cooling water, the tin will melt, which can play an indispensable role. The role of water protection.
For the installation and use of cooling water, there are several suggestions as follows:
a. The cooling water source should ensure stable water supply. It is best to use a water pump to circulate the water more reliably.
b. The cooling water should be clean and non-corrosive.
c. The cooling water temperature should not be too high and should be lower than 40°C.
d. Check that the cooling water is unobstructed before heating.
e. Do not change the induction coil soldering to copper soldering or silver soldering.
2. Device power connection
Use a soft copper wire of more than 8mm² to connect the input power as shown in the figure. The power requirement is three-phase 380V. Exceeding this range may cause damage to the equipment. Please be aware. Due to the high power of this equipment, the connection should be ensured to be firm and the contact resistance at the electrical connection should be reduced as much as possible to avoid serious voltage drops during operation and affecting the normal operation of the equipment. Users should especially avoid simply hanging the power cord on the power grid.
3. Protective ground connection
Use a wire of about 6mm² to ground the device to prevent electric shock.
4. Install the induction coil
The induction coil must pass both water and a large induction heating current, which directly affects whether the machine can be used normally. Please install it with caution. Remember not to use waterproof raw material tape during installation to avoid poor electrical connections.
5. Connect the remote control box power supply (three-phase 380V)

Indicator lights

A. Power indicator light: When the control power switch is turned on, this light is on to indicate that there is power;
B. Working indicator light: During normal heating, this light flashes and the buzzer beeps at the same time; about once per second; when the equipment fails, the sound of this light and buzzer is also abnormal, which can be used as a basis for judging equipment failure;
C. Output overvoltage indicator light: This light is on to indicate that the oscillation output voltage is overvoltage, the equipment automatically stops, and the alarm continues; shutting down and restarting can eliminate the alarm. If the alarm sounds every time it is restarted, it may be a device failure. Please refer to the fault guide;
D. Water shortage indicator light: There is a water pressure switch installed in the power supply. When the pressure of the cooling water is lower than 0.2Mpa, the equipment will automatically stop working, the water shortage indicator light will light up, and a continuous buzzer will sound; increase the water pressure, the alarm will automatically be lifted, and the water shortage indicator light will go out; When water shortage occurs, the following method can be used to try to relieve the water shortage alarm; first block the water outlet to increase the water pressure of the cooling water to make the pressure switch close, and then restore the water outlet. When the water pressure is not too low, this method can maintain the work, but when the water pressure is too low, this method is invalid and the cooling water must be improved. Please refer to the Appendix - Induction Heating Equipment Installation and Maintenance Guide.
E. Phase loss indicator: The input power of the equipment is three-phase 380V, and the control power is drawn from two phases, as shown in the schematic diagram. When a phase loss occurs, there are two situations: (1) The phase loss is one phase of the control power. At this time, the equipment has no control power, the power indicator is off, and the equipment cannot work; (2) The phase loss is one phase other than the control power. At this time, the phase loss indicator is on. The device stops working automatically and an alarm sounds;
F. Overcurrent indicator light: When this light is on, it means that the power regulation or frequency conversion regulation circuit of the device has an overcurrent phenomenon, the device stops working automatically, and emits a continuous buzzing sound; the alarm can be eliminated by turning off and then restarting. If the alarm sounds every time you restart, it may be a device failure. Please refer to the fault guide;
G. Short circuit indicator light: When this light is on and the alarm sounds, it may be that the IGBT module or auxiliary regulation board of the voltage regulation part is damaged, or the short circuit sensor is damaged. Please refer to the fault guide or consult our company for repair;
H. Input overvoltage indicator light: For devices with a three-phase 380V input voltage, the maximum input voltage allowed is 420V. When the input voltage exceeds 420V, the device will automatically stop working, the overvoltage indicator light will light, and a continuous buzzing sound will be emitted; when the input voltage is lower than 420V, the alarm will be automatically released and the overvoltage indicator light will go out;
I. Overheat indicator light: The 55°C temperature switch is installed on the heat sink of the power device, the inductor, and the capacitor box. When the temperature of these devices is higher than 55°C, the device will automatically stop working, the overheat indicator light will light up, and a continuous buzzing sound will be emitted; increase the water flow, reduce the water temperature of the cooling water, and when the temperature of these devices is lower than 55°C, the alarm will automatically be released and the overheat indicator light will go out;
J. Frequency inappropriate indicator light: When the oscillation working frequency of the device is lower than 1KHZ or higher than 20KHZ, this light will light up; the device will continue to work, but the output voltage, power, etc. will automatically decay to protect the device from damage; it can be adjusted by the following methods: (1) If the frequency is too low, the number of turns of the induction coil can be reduced, or the diameter of the induction coil can be reduced, or the capacity of the compensation capacitor can be reduced to increase the frequency; (2) If the frequency is too high, the number of turns of the induction coil can be increased, or the diameter of the induction coil can be increased, or the capacity of the compensation capacitor can be increased to reduce the frequency;
K. Frequency indicator light: This light is on to indicate that the current value displayed on the digital display is the oscillation working frequency, in KHZ;
L. Current indicator light: This light is on, indicating that the current digital display value is the output oscillation current (A);
M. Voltage indicator light: This light is on, indicating that the current digital display value is the output oscillation voltage (V);
N. Power indicator light: This light is on, indicating that the current digital display shows the power output oscillation power, in KW;

十六、中频电源的安装


安装前请详细阅读 “安装注意事项”

一、安装注意事项

1、安装前请详细阅读: 附录一感应加热设备安装・维护指南; 并按其中要求进行水电安装;
2、中频电源的输出电压为 70—550V、所以中频电源的输出端、补偿电容连接端、感应圈接头都有高压、不可暴露在外、以防操作工接触后发生触电危险;
3、中频电源、补偿电容箱、中频感应圈以及中频变压器之间需要合适的匹配、才能达到良好的加热效果、当客户自行配套或制作感应器时、请向我公司技术人员咨询;
4、中频电源与补偿电容箱之间采用同轴电缆连接、补偿电容箱与感应器间采用水冷同轴电缆连接、接头全部采用快速插头; 安装电缆快速接头时、一定要旋转后卡紧、才能达到良好的连接; 由于使用中、电缆经常摆动、快速接头很容易松开、导致接触不良、引发故障。建议: (1)安装时、先反方向将电缆拧一个角度、插入快速接头锁紧后、电缆刚好不受拧力; (2)经常检查电缆锁紧情况; (3)将快速接头处电缆固定、使电缆在操作中摆动时不会引起快速接头转动。
5、设备电气安装时应注意: 此设备属大功率设备、设备连线一定要连接牢固、尽量减少电连接处的接触电阻、绝对不可以将电源线简单地挂在电网上;
6、接地线: 用 6mm² 软铜线将设备外壳接地、以防触电。
7、冷却水: 是保证设备正常工作和长寿的关键、请用户认真阅读附录—感应加热设备安装・维护指南进行水路安装;
8、设备工作结束后、一定要继续通冷却水最少半小时。因为、中频感应熔炼和锻造加热等用途、由于加热时间长、其炉膛或炉衬溫度很高、如果一停机马上断水、会烧坏感应器、连接水管、甚至设备。
9、本说明书只涉及中频电源的安装部分、整体安装时、请按照中频全套设备安装图进行安装;


XVI. Installation of medium frequency power supply


Please read "Installation Precautions" carefully before installation


I. Installation Precautions

1. Please read carefully before installation: Appendix 1 Induction Heating Equipment Installation and Maintenance Guide; and install water and electricity according to the requirements therein;
2. The output voltage of the medium frequency power supply is 70-550V, so the output end of the medium frequency power supply, the connection end of the compensation capacitor, and the induction coil connector are all high voltage and cannot be exposed to the outside to prevent the operator from electric shock after contact;
3. The medium frequency power supply, compensation capacitor box, medium frequency induction coil and medium frequency transformer need to be properly matched to achieve a good heating effect. When customers match or make sensors by themselves, please consult our company's technical personnel;
4. The medium frequency power supply and the compensation capacitor box are connected by coaxial cable, and the compensation capacitor box and the sensor are connected by water-cooled coaxial cable. All connectors use quick plugs; when installing the cable quick connector, it must be rotated and clamped to achieve a good connection; because the cable often swings during use, the quick connector is easy to loosen, resulting in poor contact and causing failures. Suggestions: (1) When installing, first twist the cable in the opposite direction at an angle, insert it into the quick connector and tighten it, so that the cable is just not subjected to twisting force; (2) Check the cable locking condition frequently; (3) Fix the cable at the quick connector so that the cable will not cause the quick connector to rotate when it swings during operation.
5. Attention should be paid during the electrical installation of the equipment: This equipment is a high-power equipment. The equipment connection must be firmly connected to minimize the contact resistance at the electrical connection. The power cord must never be simply hung on the power grid;
6. Grounding wire: Use 6mm² soft copper wire to ground the equipment casing to prevent electric shock.
7. Cooling water: It is the key to ensure the normal operation and longevity of the equipment. Please read the Appendix - Induction Heating Equipment Installation and Maintenance Guide carefully to install the water line;
8. After the equipment is finished working, the cooling water must be continued for at least half an hour. Because, for medium frequency induction melting and forging heating, the furnace or lining temperature is very high due to the long heating time. If the water supply is cut off immediately after the machine is shut down, the sensor, connecting water pipes, and even equipment will be burned.
9. This manual only involves the installation of the medium frequency power supply. When installing the whole set, please install it according to the installation drawing of the complete set of medium frequency equipment;

Precautions for operation and use


1. Do not touch the input connector, output connector, sensor, etc. on the device after the device is powered on to prevent the risk of electric shock.
2. When the input voltage is in the range of 180-260V, please do not use the device when the voltage is higher than 270V; when the input voltage is in the range of 340-420V, please do not use the device when the voltage is higher than 430V.
3. Changes to any wiring inside or outside the device must be made after turning off the power supply of the device.
4. The device is working with high voltage, and connections or changes to the number of turns of the extension are not allowed during work. High-frequency output and input connectors must not be exposed to the outside and must not be touched during work to prevent the operator from getting an electric shock after contact.
5. When installing the device electrically, please note: This device is a high-power device, the device connection must be firmly connected, the contact resistance at the electrical connection must be minimized, and the power cord must never be simply hung on the power grid.
6. The host and extension are connected with a cable quick connector. When installing the cable quick connector, it must be plugged in tightly to achieve a good connection: Since the cable often swings during use, the quick connector is easy to loosen, resulting in poor contact and causing malfunctions. Suggestions: (1) Check the cable locking condition frequently. (2) Fix the cable at the quick connector so that the cable swings during operation without causing the quick connector to rotate.
7. The number of turns of the host and extension must be properly matched with the induction coil to achieve a good heating effect. When the customer matches or makes the induction coil by himself, please refer to the "Induction Coil Manufacturing Principles" section in this manual and consult our company's technical personnel.
8. After the work is completed, cooling water must be continued for at least 5-10 minutes.
9. The two control lines between the host and extension, a 2-core aviation plug line and a 5-core aviation plug line, play a critical role in protecting the equipment. They must be connected during work. When the extension has an abnormal phenomenon, it will be fed back to the host through these two control lines for control. The host should be disconnected in time to protect the equipment from damage. If these two lines are not connected, the use of the equipment will not be affected under normal circumstances, but when abnormal phenomena occur, the protection function will be lost and serious damage will be caused.
10. The main unit, extension unit and induction coil of the equipment must be cooled by water, and the water source must be clean to avoid blocking the cooling pipe and causing overheating and damage to the equipment.
11. The working environment of the equipment should be corrosion-free, metal dust-free, dry, clean and avoid high temperature.

感应线圈设计及安装


1. 采用壁厚 >1MM 的紫铜管、Φ8 以上圆铜管或方铜管绕制感应圈。若铜管太小或太长、其电阻热很大、将会使感应器烧损、或将冷却水加热至沸腾状态、并产生 “沸沸” 响声、应尽量避免此种现象发生。
2. 当其它条件不变时、感应圈越大、圈数越多、频率越低、分机接头匝数越大、感应圈电流越大。
3. 感应圈与加热工件部位藕合间隙在 5—15MM 为宜。
4. 导磁性差的材料如铜、铝等加热时、感应圈圈数要增加。
5. 当最大输出位置、电流显示最大、工件伸入感应圈內、电流如仍保持不变、但加热效果不好、这种情况说明: 负载太轻、或负载与感应圈间隙太小、或感应圈的圈数太少。此时要减小感应圈的尺寸、即减小感应圈与工件之间的间隙; 如果间隙已经很小、则要增加感应圈的圈数。
6. 当输出振荡电流不能调至最大、即调节旋钮调至某一位置时、一加负载、电流下降很多甚至自动停机。这说明: 负载太重、或负载与感应圈间隙过小、或感应圈的圈数太多。此时只要不会自动停机、都不影响使用、而且此时加热效率也很高。 但如果发生自动停机、则要适当增大感应圈的尺寸、即增大感应圈与工件之间的间隙。 如果说间隙已经很大、则要减小感应圈的圈数。
7. 对于工件难以置于感应圈內的平面加热、或对非磁性金属材料(如铜、铝)等的加热、可采用不同形状的导磁体(铁氧体磁芯)聚磁、可以大为增加设备的功率输出。
8. 感应圈的设计直接影响加热效果、建议使用厂家设计的感应圈、如果自行设计时、一定要向生产厂家咨询。
9. 感应圈的大小、感应圈的圈数、工件的材料和形状、分机接头数的选择、需要合适的匹配、才能达到较高的加热效率和较好的加热效果。
10. 感应圈电感太大或太小、负载太重或太轻、功率达不到额定功率、致使加热效果比较差时、需要特殊订制设备。


Induction coil design and installation


1. Use copper tubes with a wall thickness of >1MM, round copper tubes of ⌀8 or above, or square copper tubes to wind the induction coil. If the copper tube is too small or too long, its resistance heat will be very large, which will cause the sensor to burn out, or heat the cooling water to a boiling state and produce a "boiling" sound. This phenomenon should be avoided as much as possible.
2. When other conditions remain unchanged, the larger the induction coil, the more turns, the lower the frequency, the larger the number of turns of the extension connector, and the larger the induction coil current.
3. The coupling gap between the induction coil and the heated workpiece is preferably 5-15MM.
4. When materials with poor magnetic permeability such as copper and aluminum are heated, the number of induction coils must be increased.
5. When the maximum output position, the current display is maximum, and the workpiece extends into the induction coil, if the current remains unchanged but the heating effect is not good, this situation means: the load is too light, or the gap between the load and the induction coil is too small, or The number of induction coils is too few. At this time, the size of the induction coil should be reduced, that is, the gap between the induction coil and the workpiece should be reduced; if the gap is already very small, the number of turns of the induction coil should be increased.
6. When the output oscillation current cannot be adjusted to the maximum, that is, when the adjustment knob is adjusted to a certain position, when a load is added, the current will drop a lot and even stop automatically. This means: the load is too heavy, or the gap between the load and the induction coil is too small, or the number of turns of the induction coil is too many. As long as it does not stop automatically at this time, it will not affect the use, and the heating efficiency is also very high at this time. However, if automatic shutdown occurs, the size of the induction coil should be appropriately increased, that is, the gap between the induction coil and the workpiece should be increased. If the gap is already large, the number of induction coils should be reduced.
7. For flat heating where the workpiece is difficult to place in the induction coil, or for heating non-magnetic metal materials (such as copper, aluminum), different shapes of magnetic conductors (ferrite cores) can be used to collect magnetism, which can greatly improve the efficiency. Increase the power output of your device.
8. The design of the induction coil directly affects the heating effect. It is recommended to use the induction coil designed by the manufacturer. If you design it yourself, be sure to consult the manufacturer.
9. The size of the induction coil, the number of turns of the induction coil, the material and shape of the workpiece, and the selection of the number of extension joints require appropriate matching to achieve higher heating efficiency and better heating effects.
10. When the inductance of the induction coil is too large or too small, the load is too heavy or too light, and the power cannot reach the rated power, resulting in poor heating effect, special customized equipment is required.

Please refer to the installation guide or maintenance matters.
10. High frequency: When this light is on and the alarm sounds, it means that the output oscillation frequency of the device is too high, and the heating power (heating current) will automatically decay to protect the converter. At this time, it means that the sensor is not suitable, and the following methods can be used to improve it: increase the inductance of the sensor, that is, increase the number of turns, increase the diameter of the sensor, or increase the lead-out length of the sensor.
11. Low frequency: When this light is on and the alarm sounds, it means that the output oscillation frequency of the device is too low, and the heating power will automatically decay to protect the converter. This indicates that the induction coil is not suitable. It can be improved by the following methods: reduce the inductance of the inductor, that is, reduce the number of turns of the inductor, reduce the diameter of the inductor, or reduce the lead-out length of the inductor, or use a copper tube or square tube with a larger diameter to make the inductor.
12. Frequency inappropriate indicator light: When the oscillation frequency of the device is lower than the minimum frequency setting value or higher than the maximum frequency setting value, this light will be on. The device will continue to work, but the output voltage, power, etc. will automatically decay to protect the device from damage.

每周 每周检查主机和分机连接电缆是否锁紧、防止接触不良。
每3月 打开机箱采用压缩气或毛刷对设备内部除尘、去污、避免粉尘、水、油进入机器内部后造成设备故障。
每6月 用除垢剂清洗水路、当频繁出现水温报警和出水口水流量减少时、请立即检查水路和清洗水路或水泵性能。
更换感应器 定期将感应器接头和变压器输出接头用砂纸打磨干净、去掉氧化层后保证接触良好。
设备长时间未使用 再次使用前、务必打开机箱用毛刷清除机内电路板和其它部件上的灰尘、如受潮应使用电吹风彻底排除潮气再使用。
特别提示!
先通水后通电工作、设备内部及感应器必须通水冷却、必须保证冷却水清洁无杂质、水温应控制在 40℃ 以下、以免阻塞冷却水管道。避免设备在高温循环水时长时间工作、这样会加速水垢的形成造成机器故障或感应器损坏。

Every day At the end of work, drain the cooling water in the pipes inside the machine to prevent condensation and moisture inside the machine from causing malfunctions.
Weekly Check whether the connecting cables of the main unit and extension are locked every week to prevent poor contact.
Every March Open the chassis and use compressed air or a brush to remove dust and dirt inside the equipment to prevent dust, water, and oil from entering the machine and causing equipment malfunctions.
Every June Use a descaling agent to clean the water path. When water temperature alarms frequently occur and the water flow at the outlet decreases, please immediately check the water path and clean the water path or water pump performance.
Replace the sensor Regularly polish the inductor connector and transformer output connector with sandpaper to remove the oxide layer to ensure good contact.
If the equipment has not been used for a long time Before using it again, be sure to open the chassis and use a brush to remove dust on the circuit board and other components inside the machine. If it is damp, use a hair dryer to completely remove moisture before using it.
Special reminder!
First turn on the water and then turn on the power. The equipment and the sensor must be cooled by water. The cooling water must be clean and free of impurities. The water temperature should be controlled below 40°C to avoid blocking the cooling water pipe. Avoid the equipment working for a long time when the high-temperature circulating water is used. This will accelerate the formation of scale and cause machine failure or inductor damage.
