Description
Technical field
The present invention relates to a kind of GIS (gas insulated combined electrical equipment) ultrasonic partial discharge reference test bar, belongs to power equipment
Test Work tool technical field.
Background technology
Traditional GIS (gas insulated combined electrical equipment) ultrasonic partial discharge test needs tester with hand by sonac
Abut against on GIS housings acquisition internal discharge signal, and the middle discovery that works at the scene, many measurement points due to terrain clearance compared with
Height, tester's stretching hand with arm limited height and reach, need by ascending tool（Insulation double ladder or GIS special-purpose ladders）Deng
Tested, expended time efficiency low；Simultaneously, there is arm and reach and do not have in the mesophase measurement point of three-phase separate case structure
There is space to be arranged the situation of ladder, it is impossible to measure, cause test completion rate to be affected significantly.
Conventional hand sensor test, by ascending tool, expends the time compared with needs during high measurement point；In working at the scene,
For the measurement point tester of general height need to only stand i.e. measurable, and higher measurement point is run into, personnel stretch out one's hand sensing
Device can not be arrived, and can only carry out measurement of ascending a height by ladder.
In prior art, three-phase separate-box type GIS tests completion rate is not high, according to Zhejiang Electric Power Company《GIS ultrasonic waves office
Put on-the-spot test directive/guide》Requirement to measurement point, every 0.5m a measurement point should be arranged, and measurement should be arranged at main equipment
Point.But find when three-phase separate case structure GIS is tested, there are personnel and stretch out one's hand and reach test point, while ladder in scene
Situation about being also arranged without space, causes to fail to be tested according to directive/guide requirement, and completion rate is not high.If completed
Test, then need tester to lean on or climb to lay in the enterprising line sensor of housing, makes housing bear the pressure of human bady gravitational
Compel, housing may be made to be deformed causing SF6 gases to leak, jeopardize personnel and equipment safety.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of simple structure, it is easy to use can
Lean on, save the testing time, improve operating efficiency, reduce use cost, improve the GIS ultrasonic partial discharge reference test bars of measuring accuracy.
The purpose of the present invention by following technical solution completing, a kind of GIS ultrasonic partial discharges reference test bar, it includes
The one insulation body of rod, the upper end of the described insulation body of rod is connected to one can carry out 360 degree of rotary shaft bodies for rotating and positioning, and at this
The leading section of rotary shaft body is provided with ultrasonic probe, and described ultrasonic probe under a test lead by being connected to fixed installation
On insulation body of rod bottom or the receiver separately put.
As preferred：The insulation body of rod is connected through middle flexible knock-off joint by least two section telescopic bars and is constituted, institute
The rotating shaft structures that can be turned to respect to 360 degree that the rotary shaft body stated is connected by the upper end axle bed and axle bed upper end that are configured in expansion link
Connected by screw rod into, the axle bed and rotating shaft, described ultrasonic probe is installed in described rotating shaft, set in the rotating shaft
There is a U-shaped string holes, be connected with the ultrasonic probe, the ultrasonic probe is a ultrasonic sensor.
The present invention has simple structure, easy to use and reliable, saves the testing time, improves operating efficiency, and reduction is used into
Originally, the features such as improving measuring accuracy.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Shown in Fig. 1, a kind of GIS ultrasonic waves of the present invention
Reference test bar is put in office, and it includes an insulation body of rod 1, and the upper end of the described insulation body of rod 1 is connected to one can carry out 360 degree of rotations simultaneously
The rotary shaft body 2 of positioning, and ultrasonic probe 3 is installed in the leading section of the rotary shaft body 2, described ultrasonic probe 3 passes through one
It is connected under test lead 4 and is fixedly mounted on the insulation bottom of the body of rod 1 or the receiver 5 separately put.Because receiver is placed on insulation
The bottom of the body of rod 1, further needs exist for connecting an amplifier that cannot be arranged on inside the body of rod, therefore in a particular embodiment,
Described test lead is to be placed in the outside of the insulation body of rod 1 as major design.
The insulation body of rod 1 of the present invention is connected structure by least two section telescopic bar 11 through the middle joint of expansion link 11
Into described rotary shaft body 1 can be turned by what the upper end axle bed 15 and the upper end of axle bed 15 that are configured in expansion link 11 connected with respect to 360 degree
To rotating shaft 13 constitute, the axle bed 15 and rotating shaft 13 are provided with described super by screw rod connection 14 in described rotating shaft 12
Sonic probe 3, the rotating shaft 13 is provided with a U-shaped string holes 16, is connected with the ultrasonic probe 3, and the ultrasonic probe is one
Ultrasonic sensor.
The insulation body of rod 1 shown in figure is that the expansion link 11 for having three sections hollow connects through middle two flexible knock-off joints 12
Constitute afterwards together, using expansion link as the insulation body of rod, test height can effectively be adjusted according to actual needs, it is ensured that
That what is tested is normally carried out.
