  What’s the reason about medium frequency electric furnace capacitor appear to burn out?
 

Medium frequency electric furnace capacitance if appear burn out, the main reason is the following:
1, electric capacitance of the cathode grounding, if in the use of electric furnace process, the electric capacitance appear insulation bad situation, will take place capacitance cathode grounding and cause capacitor shell breakdown, if appear this kind of circumstance, you need to capacitor to deal with the insulation of the ark;

2, a shortage of water,medium frequency electric furnace in long-term use process, medium frequency furnace may in the cooling tube capacitance scum or feed water system into the trash material and lead to electric capacitance overheating and burn out. So in use process to watch the electric capacitance of the cooling water flow, if appear abnormal flow, should be the corresponding measures;

3, medium frequency voltage is too high, medium frequency electric furnace in the long-term in use process, if the medium frequency electric furnace adjustable too high, higher than the electric capacitance of the rated voltage (electric capacitance of the rated voltage 750 V and 1200 V and commonly used specifications), will cause the electric capacitance overvoltage breakdown. If appear this kind of circumstance, it needs to lower medium frequency voltage or put the electric capacitance for high stress levels of the model.
