Induction melting furnace repair: capacitor repair

The connecting bolts between the intermediate frequency compensation capacitor and the output bus bar, the bus bar and the bus bar, and the bus bar and the flexible cable are loose. Because the current flowing through the busbar is very large, the temperature of the busbar is also high during operation, so it is easy to cause the connection bolts to loosen. After the loosening, the contact resistance increases, and the temperature of the connection increases. Excessive temperature due to loosening will cause the surface of the busbar connection to be oxidized, causing poor contact and sparking. Often the inverter fails due to sparking interference. Therefore, all the connecting bolts on the busbar of the induction melting furnace should be checked and tightened frequently to cause poor contact and open circuit failure.
