Description
Technical field
The utility model relates to transformer detection technique field, particularly a kind of device being applicable to be fixed ultrasound array sensor array element.
Background technology
Along with the development of power technology, more and more higher to the requirement of Power System Reliability, transformer is as the important configuration in electric system, and its reliability of operation directly affects the safety and stablization of electric system.Find in the statistical study to transformer physical fault, insulation fault affects the main cause that transformer normally runs, the shelf depreciation of transformer is then cause the major reason of insulation fault, is therefore the importance of insulation status detection to the detection of partial discharge of transformer.
Existing transformer partial discharge positioning method mainly contains light-seeking method, electrical Location method, superfrequency position location method, x-ray excitation localization method and ultrasound wave localization method etc.Wherein ultrasound wave localization method is because its principle is simple, anti-electromagnetic interference capability is strong, cost is low, can realize the advantages such as direct geometry location, so, based on the detection method of partial discharge of electrical equipment of plane ultrasonic sensor array, the azimuth information in source can be put by the time delay relation office of obtaining between each channel ultrasound signal, and then it is accurately located.
Lack the stationary installation of plane ultrasonic sensor array array element in the market, researchist, mostly by fixing the method for multiple ultrasound element at the diverse location of electrical equipment outer wall, realizes the object of type local-discharge ultrasonic array location.And ultrasound array sensor is along with the increase of ultrasound array sensor element number of array, also can increase the direction finding precision of Partial Discharge Sources.When element number of array is increased to certain number, what direction finding precision increased is not just clearly.And, along with the increase of ultrasound array sensor element number of array, full battle array laying structure can be formed, array element distance is too tight, and array element is too much, signal " redundancy " phenomenon can be produced in Array Signal Processing algorithm, make computation process become redundancy slow, be even absorbed in " Inner eycle " of direction of arrival spectrum peak search.This makes the cost of equipment and complexity just increase.And in installation process, because array element directly inserts in blind hole, therefore in use easily cause array element to drop, reliability is lower, cannot ensure its accuracy of detection.
Utility model content
The utility model, for the deficiencies in the prior art, provides that a kind of cost is low, reliability and all higher one ten hexa-atomic annular ultrasound array sensor stationary installation of accuracy of detection.
For solving the problems of the technologies described above, the utility model institute by the following technical solutions:
A kind of ten hexa-atomic annular ultrasound array sensor stationary installations, comprise pedestal and handle, it is characterized in that, pedestal is provided with the through hole of screw thread, described through hole is 16, and is arranged on pedestal in annular, and described base bottom arranges the magnetic suction pad of annular.
Above-mentioned ten hexa-atomic annular ultrasound array sensor stationary installations, set up fixing ring flat-plate, uniform sucker on fixing ring flat-plate.
Above-mentioned ten hexa-atomic annular ultrasound array sensor stationary installations, utilize bolt to fix between described sucker and fixing ring flat-plate, and sucker is 3-10.
Above-mentioned ten hexa-atomic annular ultrasound array sensor stationary installations, described handle is arranged on the side of pedestal.
Above-mentioned ten hexa-atomic annular ultrasound array sensor stationary installations, described fixing ring flat-plate is arranged on the outer ring of magnetic suction pad, is threaded with magnetic suction pad.
The utility model has the following advantages:
The array element of ultrasound array sensor, by arranging through hole, firmly can be fixed in through-holes, the array element of ultrasound array sensor in use can not be dropped by the utility model; Through hole becomes circular arrangement on pedestal, the through hole of circular arrangement, and ultrasound wave can be made to have better acoustical behavior, and signal search is easy, and accuracy is high; The utility model adopts magnetic and sucker two kinds of fixed forms, can detect the electric equipment of ferromagnetism and nonferromagnetic.
Accompanying drawing explanation
Fig. 1 is the utility model upward view;
Fig. 2 is the utility model cross-sectional view;
Fig. 3 is the schematic diagram of fixing ring flat-plate.
In figure, each label is: 1. pedestal, 2. through hole, 3. handle, 4. bolt, 5. sucker, 6. magnetic suction pad, 7. fixing ring flat-plate, 8. ultrasound array sensor.
Embodiment
Accompanying drawings 1,2, the utility model structure comprises pedestal 1, and pedestal 1 is provided with 16 through holes, 2,16 through holes 2 arrangement in circular array, and be provided with screw thread in through hole 2, namely ultrasound array sensor 8 is plugged in through hole 2, is threaded with through hole 2; Arrange magnetic suction pad 6 bottom pedestal 1, magnetic suction pad 6 is annular, and magnetic suction pad 6 is for being fixed to electric equipment by the utility model.Meanwhile, it is fixing for being threaded with between magnetic suction pad 6 that fixing ring flat-plate 7 is placed on magnetic suction pad 6 outer ring, and namely fixing ring flat-plate 7 is detachable type, and for not needing the electric equipment using fixing ring flat-plate 7, it can according to circumstances dismounting.
Magnetic suction pad 6 is arranged on the lower bottom part of pedestal 1, can directly be adsorbed on electric equipment by magnetic suction pad 6 if device to be detected is ferromagnetic material, there is the aperture for drawing the wiring of sensor array element around magnetic suction pad 6, fixing ring flat-plate 7 being provided with equally the aperture for drawing the wiring of sensor array element.
Below fixing ring flat-plate 7, be provided with sucker 5, for the electric equipment of nonferromagnetic material, this stationary installation uses sucker 5 to be fixed on electric equipment, and sucker 5 is generally 3-10, is evenly arranged on fixing ring flat-plate 7.
Pedestal 1 and handle 3 select aircraft aluminum to make, and main chemical compositions is: aluminium, copper, zinc, magnesium, silicon etc., sucker 5 adopts fluororubber sucker.
During utility model works, for the electric equipment of ferromagnetic material, first each sensor array element is placed in through hole 2 successively, then by the wiring of sensor array element through in the fairlead of magnetic suction pad 6, rotation sensor makes it be fixed on pedestal 1; The magnetic of magnetic suction pad 6 is finally utilized to be adsorbed on the outer wall of electrical equipment by the utility model, namely install, in concrete use procedure, also need this device and other equipment connections, by the wiring access multi-channel synchronous data acquisition device of each sensor array element, can Real-time Collection type local-discharge ultrasonic array signal data.
The utility model is when being fixed on nonferromagnetic material electrical equipment outer wall, only supporting fixing ring flat-plate 7 need be fixed on magnetic suction pad 6 by screw thread peripheral, and in wiring through the fairlead passing fixing ring flat-plate 7 during magnetic suction pad fairlead simultaneously, finally utilize the suction adsorption of sucker 5 on electrical equipment outer wall.
Detect position as changed, only by handle 3, the utility model need be taken off, very convenient.
