So, in the urgent need to a kind of a kind of plateau type solid sealed pole of vacuum circuit breaker of moisture resistant, anti-dewing, anti-pollution under above-mentioned environment, thus realize perfect further to the plateau type vacuum circuit-breaker problems such as operational reliability is poor in the presence of a harsh environment, coefficient of safety is low.
Summary of the invention
The object of this invention is to provide a kind of plateau type solid sealed pole of vacuum circuit breaker of favorable sealing property, can under the environment of dust storm, humidity, filth and High aititude reliably working.
A kind of plateau type solid sealed pole of vacuum circuit breaker, comprise the pole body and pedestal that are connected, insulated tension pole is provided with in the middle of this pole body, its special feature is: also comprise insulating sealer, one end of this insulating sealer is connected with described insulated tension pole, and the other end of this insulating sealer is connected with pole body and pedestal respectively, thus form pole bore seal.
Wherein insulating sealer is made up of the top of a tubulose and a circular bottom.
The second groove of two place's ring-types is wherein provided with in the outside lower end of insulated tension pole, and the first groove of place's ring-type is provided with in pole body bottom, be provided with on insulating sealer top in addition two place's ring-types inward flange thus with the second groove fit of aforesaid two place's ring-types, and be also provided with in the bottom of insulating sealer place's ring-type outward flange thus with aforesaid place first groove fit.
Wherein insulating sealer adopts methyl vinyl silicone rubber material, this insulating sealer is provided with some steps thus has retractility.
Be wherein interference fit between one end of this insulating sealer and described insulated tension pole.
The invention has the beneficial effects as follows:
1, insulating sealer has turriform stratiform cross section, and is compressed between plateau type solid sealed pole of vacuum circuit breaker and plateau type vacuum circuit-breaker pedestal and adds creepage distance and insulation property, efficiently solves the disruptive discharge phenomenons such as creepage and flashover.
2, insulating sealer increases sealing property by an outward flange and plateau type solid sealed pole of vacuum circuit breaker bottom groove fit and two inward flanges and insulated tension pole groove interference fit, the process of plateau type solid sealed pole of vacuum circuit breaker high temperature drying sealed in actual production, such pole insulation property consistently again.
3, insulating sealer is made up of methyl vinyl silicone rubber material and is had turriform stratiform, is easy to so together do axially reciprocating with insulated tension pole and can not affect the exercise performance of plateau type vacuum circuit-breaker.
4, insulating sealer flange is that loop configuration is simple and easy to processing, low cost of manufacture, and easy for installation, pole and pedestal being screwed while, just can attach it to position.
5, under insulating sealer can be widely used in having the environment of dust storm, humidity, filth and High aititude, plateau type solid sealed pole of vacuum circuit breaker inner chamber and insulated tension pole can be made not by its performance of harsh environmental effects such as filth, humidity, condensation.

Embodiment
As shown in Figure 1,2,3, 4, the invention provides a kind of plateau type solid sealed pole of vacuum circuit breaker, comprise the pole body 1 and pedestal 3 that are connected by screw 5, insulated tension pole 4 is provided with in the middle of this pole body 1, also comprise insulating sealer 2, one end of this insulating sealer 2 is connected with described insulated tension pole 4 interference fit and its other end is connected with pole body 1 and pedestal 3 respectively thus to pole bore seal.
Wherein insulating sealer 2 is made up of the top of a tubulose and a circular bottom, the similar open-topped straw hat of its shape.The second groove 9 of two place's ring-types is provided with in the outside lower end of insulated tension pole 4, and the first groove 7 of place's ring-type is provided with in pole body 1 bottom, be provided with the inward flange 8 of two place's ring-types in addition on insulating sealer 2 top and be provided with the outward flange 6 of place's ring-type in its underpart.
Wherein insulating sealer 2 adopts methyl vinyl silicone rubber material.
As shown in Figure 2,3, 4, wherein pole body 1 is fastened on pedestal 3 by screw 5, and insulating sealer 2 is arranged between pole body 1 and pedestal 3, the outward flange 6 of insulating sealer 2 bottom is just in time pressed on groove 7 place, plateau type solid sealed pole of vacuum circuit breaker body 1 bottom first, and especially two inward flanges 8 on insulating sealer 2 top are interference fit with insulated tension pole 4 outside lower end two second groove 9.
As shown in Figure 2,3, 4, pole body 1, insulating sealer 2 and insulated tension pole 4 are coaxially arranged on the pedestal 3 of plateau type vacuum circuit-breaker of the present invention.And insulated tension pole 4 is axially connected to the inner arc control device moving contact of pole body 1 (diagram does not mark) and can axially reciprocating.Due to the axial range 14mm of insulated tension pole 4, on insulating sealer 2, two inward flanges 8 are interference fitted in groove 9 place of place second, insulated tension pole 4 outside lower end two, and the axial stretching distance that the flexible material telescopicing performance that has of insulating sealer 2 and turriform layer structure (multi-stage stairs shape) produce is greater than 14mm, thus when ensureing that insulated tension pole 4 drives one end axial motion of insulating sealer 2, the inward flange 8 on insulating sealer 2 can not come off from the second groove 9.
