One of current GIS device ultrasound wave shelf depreciation live detection main method having become as Partial Discharge Detection, it is to utilize the ultrasonic sensor being fixed on power equipment outer wall to receive the ultrasonic pulse that device interior shelf depreciation produces, with this intensity detecting shelf depreciation and position, require to choose place measurement along GIS housing axis direction at interval of about 0.5m, and measure some selection as far as possible below compartment sides, accomplish that not test leakage is not surveyed by mistake.Owing to the method is smaller by the impact of electrical Interference, therefore it is used widely in shelf depreciation positions.
Specifically carrying out in process of the test, for guaranteeing safety detection, particularly guarantee personal safety and equipment safety, except strict implement electric power relevant safety standard and security regulations, also what time require below attention: during (1) detection, should not touch other charging equipment dynamic；(2) prevent sensor from falling to GIS pipeline, it is to avoid to have an accident；(3), when using sensor in small space, health touching GIS pipeline should be avoided as far as possible；(4) when detecting, prevent from touching other parts of malfunction GIS by mistake；(5) when using sensor to detect, insulating glove should be worn, it is to avoid the direct touch sensor metal parts of hand.But GIS device compact conformation at present, detects narrow space, and some measuring point height is more than 3m even 5m, and in actual mechanical process, testing crew limbs can touch GIS device unavoidably, buries the person and equipment major safety risks.
Summary of the invention
The purpose of this utility model is to propose a kind of sensor support mechanism for ultrasound wave shelf depreciation live detection instrument, the structure of existing ultrasound wave shelf depreciation live detection instrument is improved, to ensure for highly exceeding measuring point that testing crew self elevates and working place is narrow and small cannot directly utilize the measuring point that sensor carries out detecting, GIS device can not be touched and carry out ultrasound wave shelf depreciation live detection, ensure the person and equipment safety, improve live detection efficiency simultaneously.
The sensor support mechanism for ultrasound wave shelf depreciation live detection instrument that the utility model proposes, including insulating bar, the fixing termination of sensor, rotate support bar, ultrasonic sensor arrangement room and ultrasonic signal amplifier resettlement groove, the bottom of described insulating bar is rubber handle, the upper end of insulating bar is sensor connection termination, the fixing termination of sensor is by connecting rod and insulating bar linkage, and the fixing termination of sensor is provided with core through screw rod；Described one end rotating support bar is sleeved on the core through screw rod of the fixing termination of sensor, rotates support bar and is relatively fixed by the fixing termination of direction of rotation standing screw and sensor；Described ultrasonic sensor disposes room to be fixed on the other end rotating support bar, and the sensor for detecting is fixed on ultrasonic sensor by fixing sensor bolt and disposes in room；Described ultrasonic signal amplifier resettlement groove is bolted on insulating bar by resettlement groove is fixing.
The sensor support device for GIS device ultrasound wave shelf depreciation live detection that the utility model proposes, its advantage is:
Can be prevented effectively between testing crew with GIS device unnecessary contacting, testing crew holds insulation operation handle can be affixed on measuring point surface by sensor, measure and exceed the measuring point self elevating or passing narrow regions, working place, be greatly improved the person and the equipment safety of live detection；Meanwhile, the sensor support device for GIS device ultrasound wave shelf depreciation live detection is prevented effectively from the testing crew use subtest Work tool such as lift truck, insulating ladder, saves lifting time, removes ladder and cat ladder time, hence it is evident that improves live detection efficiency.
