Description
Technical field
The present invention relates to a kind of fixed devices, more particularly to a kind of fixed device of ultra high-frequency partial discharge sensor.
Background technique
110kV combined electrical apparatus occupied area is small, performance is stablized, and has been widely used in substation.To detect group in time
Incipient fault inside electric appliance is closed, the generation of power outage is prevented, State Grid Corporation of China's " power transformation detection management specification " provides, every year
Superfrequency Partial Discharge Detection, the testing staff when carrying out superfrequency Partial Discharge Detection must be carried out to 110kV combined electrical apparatus
Ultra high-frequency partial discharge sensor must be held, is placed at combined electric disc insulator and is detected, holds detection extremely
Inconvenience, when detecting testing staff hold it is unstable can bring interference signal, influence testing result.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of fixed device of superfrequency shelf depreciation sensing, to improve spy
The detection efficiency of high frequency partial discharge sensor.
The present invention provides a kind of fixed device of ultra high-frequency partial discharge sensor, structure are as follows: including the fixed branch of sensor
Frame (7), sensor fixed bracket (7) are fixed on metal chassis (5), and the quadrangle of metal chassis (5) is respectively equipped with through-hole (9),
Bolt (3) is fixed on metal chassis (5) by through-hole (9) with hex nut (2), and bolt (3) bottom is equipped with neodymium iron boron strength
Metal chassis (5) is fixed in the flange metal connection (6) of combined electric (1) by magnet (8), neodymium iron boron strong magnets (8), Gu
The lower end of fixed rack (7) is fitted tightly on disc insulator (4).
Fixed bracket (7) the inner containment ultra high-frequency partial discharge sensor.
The bolt (3) is the combination of T shape, and stud material is iron, and base material is neodymium iron boron strong magnets (8).
The combined electric (1) is cylinder.
The present invention uses in this way: ultra high-frequency partial discharge sensor being put into fixed bracket (7), metal chassis is used
(5) ultra high-frequency partial discharge sensor is held, the neodymium iron boron strong magnets (8) of upper four bolts (3) bottom of metal chassis (5) are inhaled
In the flange metal connection (6) of disc insulator (4) two sides, ultra high-frequency partial discharge sensor and disc insulator (4) table
Face is in close contact, and is further detected.
The beneficial effects of the present invention are: structure is simple, easy to use, saves manpower, avoids interfering, use superfrequency office
When portion's discharge sensor fixes device, testing staff does not need hand-held ultra high-frequency partial discharge sensor, straight using fixed bracket
Superfrequency shelf depreciation sensor will be passed by, which connecing, is fixed on disc insulator, uses the fixed device of ultra high-frequency partial discharge sensor
Afterwards, it can eliminate due to the handshaking bring interference signal of tester, while magnet adsorption capacity is larger, energy will be closer to be sensed
Device is placed at disc insulator, avoids the interference of outer signals.
