Analysis of three major reasons for the burning of the electric heating capacitor of the induction melting furnace

1. The intermediate frequency voltage is too high. During the long-term use of the induction melting furnace, if the индукционна топилна пещ is adjusted too high, higher than the rated voltage of the electric heating capacitor, it will cause the electric heating capacitor to over-voltage breakdown. If this happens, you need to lower the intermediate frequency voltage or change the electric heating capacitor to a model with a higher voltage rating;

2. Lack of water. In the long-term use of the induction melting furnace, scale may form in the cooling pipe of the capacitor or the water inlet system may be blocked by debris, which may cause the electric heating capacitor to overheat and burn out. Therefore, pay attention to the flow of the cooling water of the electric heating capacitor during use. If the flow is abnormal, corresponding measures should be taken;

3. The cathode of the electric heating capacitor is grounded. If the electric heating capacitor has poor insulation during the use of the electric furnace, the capacitor cathode will be grounded and the capacitor casing will break down. If this happens, the capacitor cabinet needs to be The insulation is reprocessed.
