Transient grounding control device and pole-mounted vacuum circuit breaker automatic complete equipment

The utility model provides a transient grounding control device and pole-mounted vacuum circuit breaker automation complete equipment. The transient grounding control device and pole-mounted vacuum circuit breaker automation complete equipment comprises a power supply circuit, a detection circuit and a control circuit. The detection circuit collects a current signal and a voltage signal of the external distribution circuit in real time through a vacuum circuit breaker and a three-phase five-column voltage transformer of the external distribution circuit, and obtains a grounding fault judgment signal of the external distribution circuit according to the current signal and/or the voltage signal. The ground fault judgment signal is converted into a control signal to be sent to the control circuit; the control circuit is used for controlling an external distribution line to be opened/closed according to the control signal. The device provided by the utility model only needs to collect the zero-sequence current an
