What are the reasons for the overcurrent trip of 高周波焼入れ装置?

1. If the overcurrent occurs just after starting the equipment, this should be caused by the fact that the inverter lead angle is too small and the inverter thyristor cannot be turned off reliably.

2. The heat dissipation effect of high-frequency quenching equipment decreases. Often due to water quality problems, a thick layer of scale is attached to the outer wall of the cooling water system. Due to the characteristics of scale, the current is isolated, and the heat dissipation effect of the equipment is greatly reduced. In response to this problem, we need technology to clean up the scale and keep the water pipe smooth.

1. It may be that the circuit of the high-frequency quenching equipment is in poor contact or disconnected. When the connecting wires of the tank circuit have poor contact and disconnection, sparks will occur after the power rises to a certain value, which will affect the normal operation of the equipment and lead to the protection of the equipment.
