How to repair the reactor of induction heating furnace?

1. When checking the reactor coil of the induction heating furnace, it is found that the insulation of the coil is damaged. When this phenomenon occurs, it is not only to deal with the insulation of the coil, but to analyze the cause of the insulation damage. Check whether the coil fixing bolts are loose; check whether the cooling of the coil is in place; check whether the distance between the coil and the silicon steel sheet is appropriate; check whether the water path of the reactor coil of the induction heating furnace is unobstructed, etc. , otherwise, does not solve the actual problem.

2. In the maintenance of the reactor of the induction heating furnace, it is more common that the reactor coil is damaged. Therefore, when repairing the reactor coil of the induction heating furnace, do not arbitrarily adjust the coil to shorten the length of the coil and the number of coil turns, and do not arbitrarily adjust the air gap between the coil of the reactor and the silicon steel sheet, which will change the inductance of the reactor and affect the The filter function of the reactor of the induction heating furnace is adopted, which makes the output DC current appear intermittent, which leads to the unstable operation of the inverter bridge and the failure of the inverter to burn the inverter thyristor. Adjust the air gap and coil turns of the induction heating furnace reactor at will. When the inverter bridge is short-circuited, the ability of the reactor to block the current rise will be reduced, and the thyristor will be burned. The random change of the inductance of the reactor will also affect the starting performance of the equipment.
