High-voltage cable protection grounding system transfer device

The invention discloses a high-voltage cable protection grounding system transfer device, which comprises a first transfer unit U1 and a second transfer unit U2. The device has the beneficial effects that the device is internally provided with a protector and a grounding structure, according to maintenance demands, safe transfer (one box for multiple purposes) can be carried out between a protection mode and a direct grounding mode via air switches; the original cable grounding box can be replaced or maintained in the case of live cable, the device can serve as a temporary grounding device, a defected grounding box can be isolated through connection with a cable grounding line, safe operation of a maintenance person can be ensured, and a new breakthrough of lively maintaining the cable grounding system can be realized; as the device is internally integrated with current meters and voltage meters, live cable detection can be carried out after connection with the cable grounding wire, and the current load state can be intuitively analyzed through display of data of the current meters and the voltage meters in the case of maintenance; and the size is small, and carrying is convenient.
