What should I do if the MF melting furnace current is large ?

Since the new furnace, the current will not go up. Later, two capacitors (serial-parallel circuit) were added. The current is too large, the voltage is not going up, and there is time to trip. What is the reason? Answer: Then take the two capacitors off and see what the current voltage is. (There is no comparison of the current load.) I used to look at the data. I asked: The furnace is small. Answer: The furnace is small and the current will of course be reduced. Small. It is not a fault. It will be big when you adjust the board. Or if you use a few furnaces, the current will be higher. The capacitor will increase the vibration, and the current will trip. Now it has more than ten furnaces. Answer: The new furnace induction coil has leakage, which is easy to cause low voltage. Just do it. What kind of control board is your furnace? I don't know how long you have been repairing? Have time to exchange. Supplement: Capacity And the inductance of the induction coil needs to be within a certain range. Asked: How to determine this range! I am this 10T furnace answer: related to the operating frequency of the intermediate frequency melting furnace
