Why does the device stop automatically when I am using it? It turned out that the medium frequency induction heating furnace tripped automatically. This will affect your work, so we have summarized the reasons for tripping to solve your worries.
Reasons for automatic tripping of medium frequency induction furnace
Fault condition: When the intermediate frequency induction heating furnace is started, when the intermediate frequency start switch is turned on, the main circuit switch protection trips or overcurrent protection occurs.
Analysis of the cause of the phenomenon：
1. Intermediate frequency induction heating furnace current regulator failure - when the current regulator circuit fails, especially when the current transformer is damaged or the wiring is open, there is no current response suppression when starting, and the DC voltage will directly impact to the maximum (Q angle 20 degrees) , the DC current will directly hit the maximum value, causing overcurrent protection or tripping of the main circuit switch. Solution: Check whether the current transformer of the intermediate frequency furnace is damaged; whether the connection from the current transformer to the circuit board is disconnected; whether there is any component damage or open circuit in the current regulator part.
2. The power adjustment knob of the medium frequency induction heating furnace is at the highest position - except for the quenching load, other equipment requires the power adjustment knob to be at the minimum position when starting. If it is no longer at the minimum position, overcurrent protection will occur due to too large a current impact. Or the main circuit switch has tripped for maintenance.
