The steel tube heat treatment furnace is short-circuited? Find out!

steel tube heat treatment furnace will be used continuously in most factories during the period of shipment, which causes great damage to induction heating equipment, resulting in short circuit phenomenon in operation, low heating efficiency and increased economic loss. What are we supposed to do? Yuantuo has summarized many years of experience in the induction heating industry to help you solve the difficulties.

It is suggested that induction heating equipment use IGBT as power switch, which can make use of the characteristics of frequency doubling circuit to push the circuit to high frequency. In the case of a load short circuit in an induction heating device, we should scientifically select the values of Cd and LT, so that the surge current can be minimized so that the circuit can be protected more effectively. The operation of the circuit is guaranteed reliably.

The current limiting components are selected in the main circuit of the induction heating equipment, which leads to the current rising but slowly rising when the circuit is short-circuit, so that the protection circuit of the induction heating equipment has sufficient time to respond. In the induction heating equipment system, because of the high frequency and large capacity of the circuit, we ask that the protection work should be put in place quickly when the short circuit occurs. If the above cases are combined, the loss can be minimized.
