Partial discharge detection device for GIS (gas insulated switchgear)

The utility model discloses a partial discharge detection device for a gas insulated switchgear (GIS). The partial discharge detection device comprises a PDM-G01-P ultrahigh frequency partial discharge detection instrument, a discharge sensor and a sensor fixing device. The discharge sensor is fixedly arranged on the sensor fixing device through a fixing bolt and is connected with the PDM-G01-P ultrahigh frequency partial discharge detection instrument through a signal transmission cable. The discharge sensor fixing device is provided with an insulation support rod. The top end of the insulation support rod is connected with an insulation fixing plate. The partial discharge detection device can realize the quick detection for the partial discharge of the GIS, and the discharge sensor is fixed without the manpower high-altitude operation; and the partial discharge detection device has the advantages that the structure is simple, the operation is convenient, the security and the reliability are good, the detection efficiency is high, the detection cost is low, etc.
