Switch cabinet partial discharge detector

The utility model discloses a partial discharge detector for a switch cabinet, and relates to the technical field of discharge detectors. The device comprises a base, a lifting roller mechanism is arranged at the lower end of the base, a lifting cavity for the lifting roller mechanism to pass through in a lifting mode is formed in the bottom face of the base, a transverse moving mechanism is arranged on the top face of the base, a mounting column is fixedly mounted on the surface of the transverse moving mechanism, and a lifting mechanism is arranged on the surface of the mounting column. A two-stage telescopic anti-interference assembly is fixedly installed on the surface of the lifting mechanism, and a partial discharge detector body is fixedly installed on the surface of the two-stage telescopic anti-interference assembly. When a detection position needs to be switched, the partial discharge detector body can be rapidly and stably moved to a designated position only by driving the partial discharge detecto
