Problems solved by technology

However, the current GIS equipment is compact in structure and the detection space is small. Some measuring points are more than 3m or even 5m in height. During the actual operation, the test personnel will inevitably touch the GIS equipment with their limbs, burying a major safety hazard for people and equipment.

Abstract

The invention relates to a sensor support mechanism for an ultrasonic partial discharge live detector and belongs to the technical field of GIS (gas insulated switchgear) potential fault diagnosis. The mechanism comprises an insulation rod, a sensor fixing end, a rotary support rod, an ultrasonic sensor placement chamber, an ultrasonic signal amplifier placement groove and the like, wherein the upper end part of the insulation rod is a sensor connection end, the sensor fixing end is linked with the insulation rod through a connection rod, a penetrating screw is arranged at the sensor fixing end, one end of the rotary support rod is arranged on the penetrating screw of the sensor fixing end in a sleeving mode, the rotary support rod is relatively fixed with the sensor fixing end through a rotation direction fixing screw, the ultrasonic sensor placement chamber is fixed at the other end of the rotary support rod, and the ultrasonic signal amplifier placement groove is fixed on the insulation rod through a placement groove fixing screw. The sensor support mechanism can improve live detection personal and equipment safety and improve the live detection efficiency greatly.

Description

technical field [0001] The invention relates to a sensor support mechanism for an ultrasonic partial discharge electrification detector, in particular to a sensor support device for an ultrasonic partial discharge electrification detector for a gas-insulated fully enclosed combined electrical appliance, which belongs to the latent nature of gas-insulated metal-enclosed switchgear Fault diagnosis technical field. Background technique [0002] SF 6 Gas-insulated fully enclosed combined electrical appliances (hereinafter referred to as GIS) have many advantages such as small footprint, high safety, and less maintenance. The use of GIS in the last century was a huge revolution for traditional open high-voltage transmission equipment. GIS Since its inception, it has developed rapidly and has been more and more widely used in my country's power grid. Although GIS equipment has high reliability, some insulation defects may still occur during the manufacture, installation, operatio...
