Abstract

A power distribution cabinet comprises a cabinet and a control circuit. The control circuit is led into the cabinet via a cable inlet in the bottom of the cabinet. The control circuit comprises a power input, a transformer, a leakage protector, a circuit breaker, an electromagnetic brake and a motor. The power input is equipped with a switch of the circuit breaker, and is connected with the input end of the transformer through a first fuse and a second fuse which are connected in parallel. The output end of the transformer is connected with the coil of the leakage protector after being connected in series with a third fuse and a dry resistor. The coil of the leakage protector is connected with a current transformer arranged on the power input. The two ends of the coil of the leakage protector are connected in parallel with the coil of the circuit breaker and a first contact of the leakage protector which are connected in series. A second contact of the leakage protector is connected in series with a power indicator lamp and a test button and then connected in parallel to the two ends of the coil of the leakage protector. After being connected through the motor and the electromagnetic brake with a power transmission button and a power cut-off button which are connected in parallel, the circuit breaker is connected in parallel to the two ends of the coil of the leakage protector. The power distribution cabinet can realize automatic power transmission and cut-off.
