Cable protection layer grounding monitoring device

The utility model belongs to the technical field of cable protection, and particularly relates to a cable protection layer grounding monitoring device which comprises a direct grounding box, a cross interconnection grounding box, a background server and a management platform. Current transformers and voltage transformers are respectively arranged on direct grounding wires and cross interconnection grounding wires of three live wires and a zero wire of a three-phase four-wire cable, so that current and voltage data of cable grounding can be monitored in real time; and the current and voltage data are transmitted to the management platform through the background server, the management platform obtains the current and voltage data and gives an alarm through the local alarm module and the remote alarm module, so that the grounding fault of the cable can be found in the first time, the cable can be repaired in time, and the safe and stable operation of the cable is ensured. 本实用新型属于电缆保护技术领域，具体涉及一种电缆保护层接地监测装置，包括直接接地
