Protection control method for preventing overcurrent of converter tilting motor

The invention relates to a protection control method for preventing overcurrent of a converter tilting motor, and belongs to the field of electric control of converter tilting motors. According to the method, the current of the tilting motor is monitored in real time, and when the current exceeds a preset safety threshold value, a system can generate a specific signal and start timing delay; and if the current is not reduced to a safety range in the delay period, a chain reaction is triggered, and the chain reaction comprises disconnection of a normally-closed contact, cutoff of a tilting chain protection condition and power loss of a chain condition coil, so that normal operation and safety of the motor are protected. According to the invention, the stator winding and rotor insulation damage caused by motor overload can be effectively prevented, the reliability and stability of the converter tilting system are improved, the overcurrent problem can be found and processed in time, and the normal operation and
