Description

technical field [0001] The invention relates to a partial discharge detection method and a partial discharge detection device, belonging to the technical field of electric variable measurement. Background technique [0002] For primary grid equipment such as gas-insulated metal-enclosed switchgear (GIS) and high-voltage switchgear, its internal structure is complex. After a long time of operation, partial discharges are often caused by aging electrical components, dirty surfaces of insulating objects, and peeling off of internal paint. If it cannot be detected in time, it will cause grounding short-circuit tripping after a long time, which will cause a power outage. Therefore, during the operation of the equipment, it is necessary to regularly conduct partial discharge detection on GIS equipment, high-voltage switchgear, etc., and internally measure them through UHF, ultrasonic, and transient ground voltage measuring instruments to check whether there is partial discharge. ...
