Example of induction furnace fault 8

Fault phenomenon: when the equipment is running, the DC voltage and intermediate frequency voltage have reached the rated value, but the DC current is small and the power is low.

Fault analysis and treatment: the fault is caused by high load impedance.

A. insufficient compensation of load compensation capacitor

B. the power saving contact resistance of the connecting wire of the slot circuit (LC oscillation circuit) is too large - due to the long-term use, the contact resistance of the copper bar of the slot circuit is affected by the dust, which increases the resistance of the load and causes this fault phenomenon in the induction melting furnace.
