Transformer direct current resistance test lead clamp

The invention provides a transformer direct-current resistance test lead clamp, which belongs to the technical field of substation high-voltage equipment acceptance test and comprises a metal clamp, a connector, a hollow insulating rod, an insulating handle, a safety lock, a pull rope and a test lead. The other end of the hollow insulating rod is provided with an insulating handle, and the insulating handle is rotatably connected with the hollow insulating rod. The metal clamp comprises two metal clamping jaws which are symmetrically arranged, and the two metal clamping jaws are rotationally connected to the connector; the safety lock is connected between the insulating handle and the hollow insulating rod, and when the safety lock is locked, the relative positions of the insulating handle and the hollow insulating rod are not changed; the pull rope passes through the hollow insulating rod, and one end of the pull rope far away from the connector is fixedly connected to the insulating handle.
