Power system relay protection secondary circuit disconnection and butt joint calibrator

The invention relates to the field of power systems, in particular to a power system relay protection secondary circuit disconnection and butt joint calibrator which comprises a relay protection secondary cable core positioning buckle, a clamping sleeve, a master control module and a controlled module. The main control module and the controlled module are respectively connected with the two groups of relay protection secondary cable core positioning buckles, and the main control module is internally provided with a transceiver for controlling the relay group and establishing communication with the controlled module; and the controlled module is used for receiving the signal from the main control module and adjusting and controlling equipment in the secondary loop. The unique topological relation is established through the main control module and the controlled module, the uniqueness of each group of power system relay protection secondary circuit disconnecting and connecting butt joint device is ensured, corr
