Description

A kind of plateau type solid sealed pole of vacuum circuit breaker
Technical field
The present invention relates to a kind of plateau type solid sealed pole of vacuum circuit breaker.
Background technology
Plateau type vacuum circuit breaker is to turn on and disconnects unloaded and load current in high-tension circuit, and can rapid disengagement failure The switchgear of electric current.Pole is as plateau type vacuum circuit breaker core component by poor reliability, peace under adverse circumstances Overall coefficient is low, especially in the environment of having dust storm, humidity, filth and High aititude, pole inner surface and insulated tension pole table Face is also easy to produce flashover, climbs the electric discharge of damaging property of the phenomenon such as electricity and damage pole.
So, in the urgent need to a kind of moisture resistant under above-mentioned environment, anti-dewing, anti-pollution a kind of plateau type vacuum circuit breaker Device pole, so as to realize that operational reliability is poor in the presence of a harsh environment, safety coefficient is low asks to plateau type vacuum circuit breaker That inscribes is further perfect.
The content of the invention
It is an object of the invention to provide a kind of plateau type solid sealed pole of vacuum circuit breaker of favorable sealing property, can be in wind Reliably working in the environment of husky, moist, filthy and High aititude.
A kind of plateau type solid sealed pole of vacuum circuit breaker, including the pole body and pedestal being connected, in the sealing Insulated tension pole is provided with the middle of pole body, it is particular in that:Also include insulating sealer, one end of the insulating sealer with Described insulated tension pole connection, and the other end of the insulating sealer is connected with pole body and pedestal respectively, so that shape Into pole bore seal.
Wherein insulating sealer is made up of the top of tubulose and the bottom of an annular shape.
Lower end is provided with the second groove of ring-type at two wherein outside insulated tension pole, and is provided with pole body bottom First groove of ring-type at one, is provided with the inward flange of ring-type at two so as to ring at foregoing two on insulating sealer top in addition Second groove fit of shape, and the outward flange of ring-type at also is provided with so as at foregoing one the in the bottom of insulating sealer One groove fit.
Wherein insulating sealer use methyl vinyl silicone rubber material, be provided with the insulating sealer some steps from And there is retractility.
It is interference fit wherein between one end of the insulating sealer and described insulated tension pole.
The beneficial effects of the invention are as follows:
1st, insulating sealer has a turriform stratiform cross section, and be compressed in plateau type solid sealed pole of vacuum circuit breaker with Creep age distance and insulating properties are increased between plateau type vacuum circuit breaker pedestal, is efficiently solved and is climbed the destruction such as electricity and flashover Property electric discharge phenomena.
2nd, insulating sealer passes through an outward flange and plateau type solid sealed pole of vacuum circuit breaker bottom groove fit and two Inward flange increases sealing property with insulated tension pole groove interference fit, by plateau type vacuum breaker fixing-sealing in actual production The treatment of pole high temperature drying is sealed again, and such pole insulating properties are remained the same from beginning to end.
3rd, insulating sealer is made up and with turriform stratiform of methyl vinyl silicone rubber material, is so easy to be drawn with insulation Bar together does axially reciprocating without influenceing the exercise performance of plateau type vacuum circuit breaker.
4th, insulating sealer flange is the simple easy processing of loop configuration, low cost of manufacture, and easy for installation, by sealing Pole is screwed while position can be attached it to pedestal.
5th, in the environment of insulating sealer can be widely applied to dust storm, humidity, filth and High aititude, may be such that plateau type Solid sealed pole of vacuum circuit breaker inner chamber and insulated tension pole do not influence its performance by the adverse circumstances such as filth, humidity, condensation.

Specific embodiment
As shown in Figure 1,2,3, 4, the invention provides a kind of plateau type solid sealed pole of vacuum circuit breaker, including by screw The 5 pole bodies 1 and pedestal 3 being connected, insulated tension pole 4 is provided with the middle of the pole body 1, also close including insulating Sealing 2, one end of the insulating sealer 2 be connected with the described interference fit of insulated tension pole 4 and its other end respectively with sealing pole Post body 1 and the connection of pedestal 3 are so as to pole bore seal.
Wherein insulating sealer 2 is made up of the top of tubulose and the bottom of an annular shape, is shaped like top The straw hat of opening.The second groove 9 of ring-type at two is provided with the outside lower end of insulated tension pole 4, and is set in the bottom of pole body 1 There is the first groove 7 of ring-type at, be provided with the inward flange 8 of ring-type at two on the top of insulating sealer 2 in addition and set in its underpart There is the outward flange 6 of ring-type at.
Wherein insulating sealer 2 uses 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 pacified Between pole body 1 and pedestal 3, the outward flange 6 of the bottom of insulating sealer 2 is just pressed on plateau type vacuum circuit breaker At the first groove of bottom 7 of device pole body 1, especially two inward flanges 8 on the top of insulating sealer 2 and insulated tension pole 4 The groove 9 of outside lower end two second is interference fit
As shown in Figure 2,3, 4, pole body 1, insulating sealer 2 and insulated tension pole 4 are coaxially mounted to of the invention On the pedestal 3 of plateau type vacuum circuit breaker.And insulated tension pole 4 is connected axially to the inside arc-chutes moving contact of pole body 1 (diagram is not marked) and can be with axially reciprocating.Due to the axial range 14mm of insulated tension pole 4, on insulating sealer 2 Two inward flanges 8 are interference fitted at the outside lower end two of insulated tension pole 4 at second groove 9, and the flexibility that insulating sealer 2 has The axial stretching distance that material telescopicing performance and turriform layer structure (multi-stage stairs shape) are produced is more than 14mm, so as to ensure insulation When pull bar 4 drives one end of insulating sealer 2 to be axially moved, the inward flange 8 on insulating sealer 2 will not be from the second groove 9 Come off.
