The test stand can directly inspect completeness of a vacuum interrupter, and separation of an upper contact and a lower contact of the vacuum interrupter can be realized by adjusting the top board bolt.
Description
Technical field
The utility model relates to the stationary installation of electric elements being carried out AC voltage withstand test, particularly can be used for the testing table that breaker vacuum bulb carries out the ac high-voltage withstand voltage test.
Background technology
Can run into the fault of the vacuum bubbles damage of vacuum circuit breaker in maintenance repair work, vacuum bubbles is disposable can not the reparation, the vacuum bubbles that can only more renew.The replacing process is complicated, and the vacuum bubbles of changing does not also know it is bad, the isolating switch of finishing changing vacuum bubbles can only be in gate-dividing state and could check out quality.
The utility model content
The purpose of this utility model provides a kind of breaker vacuum pipe fracture alternative-current withstand voltage test platform, so that directly vacuum bubbles is carried out the high pressure withstand voltage test, change to the present situation of checking the vacuum bubbles quality on the isolating switch again thereby change, avoid changing to the trouble that isolating switch takes off replacing more again damaging vacuum bubbles.
This novel purpose is achieved in that a kind of breaker vacuum pipe fracture alternative-current withstand voltage test platform, and many insulating bars are fixed between steel substrate and the insulation top board, and every insulating bar middle part is provided with insulator; Steel substrate is provided with the structure that is connected and fixed as vacuum bubbles lower end rifled tube: the steel pipe that patches that inserts as vacuum bubbles lower end rifled tube is welded on the steel substrate, patch the external diameter of the internal diameter of steel pipe greater than vacuum tube lower end rifled tube, tight fixed bolt is screwed in and patches on the steel pipe, perhaps, steel pipe is welded on the steel substrate, and the steel pipe upper end is welded with as the bolt that is connected with vacuum tube lower end rifled tube spiral; After roof bolt is passed the hole of insulation on the top board from the top down, be screwed on the rifled tube of vacuum bubbles upper end again, and be connected with first nut and second nut on the roof bolt, first nut and second nut lay respectively at the above and below of insulation top board.
Also be fixed with rule on the above-mentioned insulation top board, be fixed with the pointer of indicating graduation on the roof bolt.
The shape of above-mentioned steel substrate and insulation top board is equilateral triangle, and insulating bar is 3, and 3 insulating bars are separately fixed at three corner position places of equilateral triangle.
Uniformly below the above-mentioned steel substrate be provided with three insulation footings, and steel substrate is provided with ground wire.
This is novel to have following characteristics and advantage:
1, the quality of vacuum bubbles need not change on the isolating switch and just can check out quality, reduces the working time, reduces the isolating switch power off time.
2, be convenient to check the quality of stock's vacuum bubbles, be convenient to management.
3, alleviate the working strength of changing vacuum bubbles work maintenance.
4, be applicable to various types of vacuum bubbles checks, the upper and lower clearance between open contacts of vacuum bubbles can be realized by regulating roof bolt.
Description of drawings
Fig. 1 is the stereographic map of this novel embodiment;
Fig. 2 is the stereographic map of this novel another embodiment.
Embodiment
Fig. 2 illustrates, and many insulating bars 3 are fixed between steel substrate 2 and the insulation top board 5, and every insulating bar middle part is provided with insulator 4; Steel substrate 2 is provided with the structure that is connected and fixed as vacuum bubbles 10 lower end rifled tubes: the steel pipe 7 that patches that inserts as vacuum bubbles lower end rifled tube is welded on the steel substrate, patch the external diameter of the internal diameter of steel pipe 7 greater than vacuum tube lower end rifled tube, tight fixed bolt 8 is screwed in and patches on the steel pipe 7, perhaps (referring to Fig. 1), steel pipe 7a is welded on the steel substrate, and steel pipe 7a upper end is welded with as the bolt 9 that is connected with vacuum tube lower end rifled tube spiral; After roof bolt 13 is passed the hole of insulation on the top board 5 from the top down, be screwed in again on the vacuum bubbles 10 upper end rifled tubes, and be connected with the above and below that first nut 12 and second nut, 11, the first nuts 12 and second nut 11 lay respectively at the insulation top board on the roof bolt.
Also be fixed with rule 6 on the insulation top board 5, be fixed with the pointer 14 of indicating graduation on the roof bolt 13.The shape of steel substrate 2 and insulation top board 5 is equilateral triangle, and insulating bar 3 is 3, and 3 insulating bars are separately fixed at three corner position places of equilateral triangle.Uniformly below the steel substrate 2 be provided with three insulation footings 1, and steel substrate 2 is provided with ground wire.
Fig. 1 Fig. 2 difference only is the difference of the syndeton of vacuum bubbles lower end, and remainder is identical.
Connect with bolt at the vacuum bubbles two ends, also add insulator again with the insulating bar support between steel substrate and the insulation top board and reliably insulate.The vacuum bubbles bottom is fixed by bolts to (all there is a hole at the vacuum bubbles two ends) on the base plate, and the upper end bolt passes the insulation top board from the top down, is screwed on the last terminal filament hole of vacuum bubbles, just the upper and lower contact in the vacuum bubbles is drawn back when tightening roof bolt, realizes gate-dividing state.
The vacuum bubbles method of inspection:
The quality of vacuum bubbles is exactly to check the vacuum tightness of vacuum bubbles.Regulate the upper and lower clearance between open contacts of vacuum bubbles according to the rated capacity of vacuum bubbles, make the upper and lower contact of vacuum bubbles be in the separated position (isolating switch is in gate-dividing state) of a determining deviation, be added between the contact fracture one minute with 4.2 ten thousand volts of ac voltage withstandings.
