In the secondary work of the transformer substation, equipment in a protection screen, a terminal box and a switch cabinet is often debugged and overhauled. In the debugging process, sampling or logic verification is needed to be carried out on an external test wire. In the process of externally connecting the test wire, a mode of directly connecting the wire on a current and voltage terminal is generally adopted. The existing current terminal is generally a terminal with a scribing sheet and an external test wire socket, and the voltage terminal is a straight-through terminal without the test wire socket, so that the test wire is connected into the terminal after the original external side or internal side wiring is prepared for insulation during operation.
