ਉੱਚ ਫ੍ਰੀਕੁਐਂਸੀ ਬੁਝਾਉਣ ਵਾਲੇ ਉਪਕਰਣਾਂ ਦੀਆਂ ਆਮ ਨੁਕਸ ਅਤੇ ਸਮੱਸਿਆ ਨਿਪਟਾਰਾ ਕਰਨ ਦੇ ਤਰੀਕੇ
ਦੇ ਆਮ ਨੁਕਸ ਅਤੇ ਸਮੱਸਿਆ ਨਿਪਟਾਰੇ ਦੇ ਢੰਗ ਉੱਚ ਆਵਿਰਤੀ ਬੁਝਾਉਣ ਵਾਲੇ ਉਪਕਰਣ
1. Fault phenomenon The high-frequency quenching equipment is running normally, but the bypass reactor is heated and burned out.
The main reasons for the heating and burning of the bypass reactor are as follows:
(1) The quality of the bypass reactor itself is not good;
(2) There is asymmetric operation of the inverter circuit, and the main reason for the asymmetric operation of the inverter circuit comes from the signal loop.
2. Fault phenomenon The high-frequency quenching equipment operates normally and often breaks down the compensation capacitor. The cause of the fault:
(1) The intermediate frequency voltage and operating frequency are too high;
(2) The capacitor configuration is not enough;
(3) In the capacitor boost circuit, the capacity difference between the series capacitor and the parallel capacitor is too large, resulting in uneven voltage breakdown of the capacitor;
(4) Cooling is not good for breakdown capacitors.
3. Failure phenomenon The high-frequency quenching equipment operates normally but frequently overcurrent.
When the equipment is running, the waveform and sound of various electrical parameters are normal, that is, frequent overcurrent. When such a fault occurs, pay attention to whether it is due to improper wiring that generates electromagnetic interference and parasitic parameter coupling interference between lines, such as strong wires and weak wires. , the power frequency line and the intermediate frequency line are laid together, the signal line is intertwined with the strong wire, the intermediate frequency line busbar, etc.
