Abstract
The utility model discloses a test-tube for simulating solid sealed pole post motion, comprising a base plate and a top plate; the top plate is arranged on the base plate and is fixed with the base plate; the base plate and the top plate are provided with corresponding through holes; a bumping plate is arranged above the through hole of the top plate and is fixed with the top plate; a moving contact penetrates in the middle of the through hole of the top plate and is located under the bumping plate; an insulation pull bar penetrates in the middle of the through hole of the base plate and is fixed with the moving contact; the base plate is provided with installing holes; preferably the insulation pull bar and the moving contact are locked through threaded connection; the base plate and the top plate can be fixed through a plurality of screws; the top plate and the bumping plate can also be fixed through a plurality of screws. The test-tube is low in manufacture costs, can substitute for solid sealed pole posts of a vacuum circuit breaker to perform operating mechanism reliability tests and reduces production costs of the vacuum circuit breaker on the whole.
Description
Technical field
The utility model relates to vacuum circuit breaker experimental technique field, especially a kind of developmental tube of simulating the pole action.
Background technology
Shown in Figure 3 is a kind of vertical view of known vacuum circuit breaker, three poles 20 is housed, on the housing of operating mechanism 10 in the production standard; 500 vacuum circuit breakers of every production just need make an experiment to the reliability of operating mechanism 10 actions; After but test was accomplished, three poles 20 were scrapped basically, can not refill on the product; Because the cost of each pole is between several thousand yuan to several ten thousand yuan, this test can be produced bigger waste; Therefore be badly in need of a kind of pole of simulating of design and move and lower-cost developmental tube, the utility model produces thus.
The utility model content
The technical matters that the utility model will solve provides a kind of developmental tube of simulating the pole action, and its low cost of manufacture can replace the pole on the vacuum circuit breaker to carry out the operating mechanism fail-test, reduces the production cost of vacuum circuit breaker on the whole.
For achieving the above object; The technical scheme of the utility model is: a kind of developmental tube of simulating the pole action, comprise base plate, top board, and top board is arranged on the top of base plate and fixes with base plate; Base plate and top board are provided with corresponding through hole; Be provided with a crash panel above the top board through hole, crash panel and top board fix, a moving contact be through the centre of top board through hole and be in crash panel below; Centre and moving contact that one insulated tension pole is through bottom hole fix, and also are provided with mounting hole on the base plate.
Described moving contact bottom is provided with internal thread, and the top of insulated tension pole is provided with external thread, and insulated tension pole and moving contact be through the locking mutually that is threaded, and makes things convenient for being connected and dismounting of insulated tension pole and moving contact.
Described base plate and top board fix through many screw rods, and simple in structure and length through the adjustment screw rod can change the spacing of base plate and top board.
Described top board and crash panel fix through many screw rods, and simple in structure and length through the adjustment screw rod can change the spacing of top board and crash panel.
The crash panel of the utility model is equivalent to the static contact of pole; The moving contact of the utility model is equivalent to the moving contact in the pole; Mounting hole on the base plate capable of using is installed to the utility model on the housing of vacuum circuit breaker operating mechanism; Be connected with vacuum circuit breaker operating mechanism through insulated tension pole again; The moving contact of the utility model and the action that crash panel collides just are equivalent to pole moving contact and static contact in the indoor action that combines of vacuum extinction, so the utility model can replace the pole on the vacuum circuit breaker to carry out the operating mechanism fail-test.
On the other hand; The utility model is simple in structure to be made up of several metalworks; Manufacturing cost is very low, replaces pole to install on the operating mechanism of vacuum circuit breaker with it and carries out fail-test, just reduce the loss of pole; Simultaneously the utility model can also recycle, therefore reduces the production cost of vacuum circuit breaker on the whole.
Description of drawings
Fig. 1 is the utility model front view;
Fig. 2 is the utility model stereographic map;
Fig. 3 is a kind of vertical view of known vacuum circuit breaker;
Fig. 4 is that the utility model replaces pole to be installed in the vertical view on the vacuum circuit breaker operating mechanism.
Embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1, shown in Figure 2; A kind of developmental tube 30 of simulating the pole action comprises base plate 1, top board 2, and top board 2 is arranged on the top of base plate 1 and fixes with base plate 1; Base plate 1 is provided with corresponding through hole 11,21 with top board 2; Be provided with a crash panel 3 above top board 2 through holes 21, crash panel 3 fixes with top board 2, a moving contact 4 be through the centre of top board 2 through holes 21 and be in crash panel 3 below; Centre and moving contact 4 that one insulated tension pole 5 is through base plate 1 through hole 11 fix, and also are provided with mounting hole 12 on the base plate 1.
Can be provided with internal thread in moving contact 4 bottoms, be provided with external thread on the top of insulated tension pole 5, insulated tension pole 5 can also make things convenient for the dismounting between them through the locking mutually that is threaded with moving contact 4 like this.
Described base plate 1 fixes through many screw rods 6 with top board 2.
Described top board 2 fixes through many screw rods 7 with crash panel 3.
Fig. 4 illustrates the utility model and replaces pole to be installed in the vertical view on the vacuum circuit breaker operating mechanism; Three developmental tubes 30 are housed on the housing of operating mechanism 10; The installation site of three developmental tubes 30 is identical with the installation site of three poles of vacuum circuit breaker; Utilize three insulated tension poles on the developmental tube 30 to be connected with operating mechanism again, the utility model just can replace pole that the operating mechanism on the vacuum circuit breaker is carried out fail-test.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
