Technical requirements for induction melting furnace compensation capacitor cabinet
The induction melting furnace compensation capacitor cabinet has a solid overall structure and beautiful appearance. The double-layer mica insulation technology is used for the insulation treatment of the capacitor. Even if water is sprayed on the capacitor accidentally, the insulation strength of the cabinet can be ensured.
In order to reduce the loss of the high current loop , the compensating capacitor bank is installed in the basement as close as possible to the induction melting furnace . All capacitors adopt new high-capacity non-toxic medium water-cooled RFM series electric heating capacitors, which have the advantages of large single capacity, low dielectric loss and small floor space. The capacitor cabinet is installed near the furnace body, which can reduce the loss of the tank and improve the efficiency. A temperature monitoring point is installed in the capacitor cabinet to ensure stable operation of the power supply.
