Jinan Inverter Maintenance: Soft starter has many maintenance functions, if current, overvoltage, overvoltage protection. With the continuous improvement of industrial control automation level, soft starter has also been widely used.
The reason of leakage protection tripping is that the output waveform of soft starter has high pulse current, and the leakage current is caused by the cable between the motor and soft starter. The leakage current is much larger than that of the DC driver motor, so this situation is caused.
The leakage current of the output side of the converter is about three times as much as that of the power frequency operation. When the leakage current of the motor is applied, the action current of the leakage protector should be 10 times as much as that of the power frequency operation. Where the frequency converter is used, it is not suitable to use the protective switch with leakage protection function.
Because of the high pulse current in the output of the converter, it is inevitable that the leakage current will exceed 30 mAh and make the leakage protector jump if it is not for the special converter cable and motor.
