Common faults of medium frequency electric furnace equipment

Medium frequency electric furnace equipment is widely used in iron and steel, casting, special steel and other related fields. Different application fields have different requirements for medium frequency electric furnace equipment. Only on the basis of mastering the basic working principle of these circuits and the basic characteristics of power devices, can we quickly and accurately analyze and judge the cause of the fault, and take effective measures to eliminate the fault What common faults do you have? Please enjoy the explanation below.

1. Start up, if electric furnace equipment cannot be started normally

Fault phenomenon: large DC current, low DC voltage and if voltage when starting, dull equipment sound.

2. The equipment can be started, but the working state of medium frequency electric furnace equipment is not correct

Fault phenomenon: the equipment can be started normally and smoothly. When the power rises to a certain value, overvoltage or overcurrent protection will be provided.

3. Faults easy to occur during normal operation of medium frequency electric furnace equipment

Fault phenomenon: the equipment operates normally, but when the normal overcurrent protection acts, several KP thyristors and fast melting are burned.

The above three points are the common faults of medium frequency electric furnace equipment. If you want to know how to solve these problems, please see the next part.
