Technical Field
The utility model relates to a general type compression joint device of an ultrasonic sensor for GIS and GIL equipment partial discharge detection.
Background
At present, when the ultrasonic partial discharge detection device effectively used at home and abroad is used for ultrasonic partial discharge detection, an ultrasonic sensor generally needs to be adhered to a tank shell through a coupling agent or needs to be held by a hand-held sensor of a detector to obtain a result in conventional operation.
