Design and protection of Biyuanda electromagnetic heater

The performance of each component of the electromagnetic heater is as follows:

1. Electromagnetic heater chassis: The dustproof design of the circuit is adopted to ensure the service life of the electromagnetic heater.

2, electromagnetic heater IGBT temperature sensor: high-precision thermistor (70 degrees). The imported thermal grease is used to transfer the heat of the IGBT to ensure the safety of the IGBT module.

3, electromagnetic heater fan: use brushless AC fan, and brush fan than the air volume, life expectancy of up to 20,000 hours, low noise (≤ 45dB)

4, electromagnetic heater power supply: mainly use high-performance switching power supply.

5, electromagnetic heater IGBT: the world's top Infineon module (high speed, anti-high voltage, high operating current, stability is particularly good).

6, electromagnetic heater heat sink: self-design, fully meet the heat dissipation requirements of the circuit.

7, electromagnetic heater high voltage capacitor: high voltage, high frequency, high precision, low loss.


Biyuanda electromagnetic heater 16 safety guarantee

1. Overcurrent protection: When the current exceeds the rated current of the electromagnetic heater core, the electromagnetic heater automatically reduces the current or temporarily stops heating.

2. Overvoltage protection: When the three-phase power supply voltage exceeds 450V continuously, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm sound.

3. Undervoltage protection: When the three-phase power supply voltage exceeds 330V continuously, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm sound.

4, electromagnetic heating coil short circuit protection: When the coil is short circuited or open circuit, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm sound.

5, IGBT module short circuit protection: When the IGBT module is short circuited, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm sound.

6. Open circuit protection of IGBT module: When the IGBT module is open, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm.

7. IGBT module overheat protection: When the IGBT module overheats, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm.

8. Over-current protection of IGBT module: When the current of the IGBT module is too high, the electromagnetic heater does not work, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm.

9. Overheat protection: When the AC cooling fan is broken or Other reasons (such as: IGBT over temperature, etc.), the electromagnetic heater does not work when the temperature inside the machine rises sharply. The digital tube displays the corresponding fault code and the buzzer sounds.

10, waterproof and moisture protection: Electromagnetic heating control board has been waterproof and moisture-proof treatment, if the electromagnetic heating coil accidentally enters the water, as long as the water is cleaned, the electromagnetic heater will automatically recover, and the boot will enter the normal working state.

11. Surge protection: When the power supply surge voltage occurs, the electromagnetic heater stops heating immediately, and the surge automatically disappears after two seconds.

12, anti-dry protection: When the temperature of the barrel reaches the Curie point, the electromagnetic heater does not heat, the digital tube displays the corresponding fault code, and the buzzer sounds an alarm.

13. Lightning protection: When high-voltage interference occurs during lightning strikes in the rainy day, the electromagnetic heater will temporarily stop the protection, and then automatically resume heating after the lightning strike.

14. Leakage protection: When the electromagnetic heater detects that there is leakage outside, the electromagnetic heater stops heating immediately and cuts off the three-phase power input, displays the corresponding code and alarms.

15. Phase loss protection: When three-phase power input, any one phase or two phases are missing, the electromagnetic heater stops heating.

16. No load protection: When no barrel or other load is detected, the electromagnetic heater will automatically power off and stop working.
