The insulating sealing device provided by the utility model has the advantages the insulating sealing device is simple in machining technique and has strong insulating sealing capability; the entire sealed pole is formed by externally coating silicon rubber in a compression molding manner and internally pouring the epoxy resin; and the combined insulation is used, so that the insulating sealing level is greatly improved.
Description
Technical field
The utility model relates to sealing device, relates in particular to a kind of insulation seal device of vacuum interrupter pole.
Background technology
Pole is that the conductive component with vacuum interrupter and circuit breaker is embedded into this type of epoxy resin simultaneously and forms pole in the cured solid insulating material easily, makes whole circuit breaker polar become as a whole parts.
At present; The external insulation Sealing Technology that is used for the vacuum interrupter on the outdoor vacuum circuit breaker has two kinds: a kind of is to put into mould to vacuum interrupter to form with the epoxide resin material compacting; This method manufacturing procedure is loaded down with trivial details; And owing to be that high-pressure molding causes vacuum interrupter to withstand shocks, must on the surface of vacuum interrupter, be coated with and be covered with padded coaming, utilize the strain of padded coaming to alleviate the suffered pressure of vacuum interrupter.Like this, increase combination interface, made non-uniform electric, reduced the integral insulation sealability of phase post.
Another kind is to adopt silastic material to be pressed into insulating cylinder; Putting into the embedding of vacuum interrupter reusable liquid silicon rubber then forms; Though this method manufacturing procedure is simple, because the silicon rubber encapsulation technology is not overripened, the surperficial degree of adhesion that the silastic material of embedding solidifies back and vacuum interrupter is difficult to guarantee; Because the silicon rubber inside after solidifying is easy to generate bubble, these have all influenced the insulated enclosure ability of pole simultaneously.
The utility model content
The technical problem that the utility model will solve is: provide a kind of processing technology simple, the sealing device of the vacuum interrupter pole that the insulated enclosure ability is strong.
In order to overcome the defective that exists in the background technology; The utility model solves the technical scheme that its technical problem adopted: a kind of insulation seal device of vacuum interrupter pole; Comprise shell and vacuum interrupter, it is characterized in that: said case surface coating silicon rubber layer, said vacuum interrupter is arranged on enclosure; Between said shell and the vacuum interrupter epoxy resin layer is set; Said shell is fixedly connected with the quiet end of vacuum interrupter, and the end of said vacuum interrupter moved end is provided with positioning sleeve, and said positioning sleeve is connected with the end seal of vacuum interrupter moved end.
According to another embodiment of the utility model, said silicon rubber filling is in the gap of shell and vacuum interrupter.
According to another embodiment of the utility model, the quiet end of said vacuum interrupter is fixedly connected with shell through nut.
According to another embodiment of the utility model, said positioning sleeve is connected with the end seal of vacuum interrupter moved end through sealing ring.
According to another embodiment of the utility model, said sealing ring is the O RunddichtringO.
The utility model has solved the defective that exists in the background technology; Provide a kind of processing technology simple; The sealing device of the vacuum interrupter pole that the insulated enclosure ability is strong, whole pole are to adopt that outer to cover silicon rubber mould molded, and inner casting epoxy resin is made; Adopted compound inslation, the insulated enclosure level is improved greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the preferred embodiment of the utility model;
Wherein: 1, shell, 2, vacuum interrupter, 3, silastic-layer, 4, epoxy resin layer, 5, the quiet end of vacuum interrupter, 6, the vacuum interrupter moved end, 7, positioning sleeve, 8, nut, 9, sealing ring.
Embodiment
Combine accompanying drawing and preferred embodiment that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The insulation seal device of a kind of vacuum interrupter pole as shown in Figure 1; Comprise shell 1 and vacuum interrupter 2, said shell 1 surface coated silastic layer 3, said vacuum interrupter 2 is arranged on shell 1 inside; Between said shell 1 and the vacuum interrupter 2 epoxy resin layer 4 is set; Said shell 1 is fixedly connected with the quiet end 5 of vacuum interrupter, and the end of said vacuum interrupter moved end 6 is provided with positioning sleeve 7, and said positioning sleeve 7 is connected with the end seal of vacuum interrupter moved end 6.
The utility model utilizes silastic-layer 3 covering shells surfaces, between shell 1 and the vacuum interrupter 2 epoxy resin layer 4 is set, simultaneously also silicon rubber filling in the gap of shell 1 and vacuum interrupter 2; Vacuum interrupter 1 and outside insulation have been guaranteed; And safe and reliable, promptly whole pole is to adopt that outer to cover silicon rubber mould molded, and inner casting epoxy resin is made; Adopted compound inslation, insulation level is improved greatly.
The quiet end 5 of vacuum interrupter described in the utility model is fixedly connected with shell 1, adopts nut 8 to be fixedly connected between them.Nut connects and generally is used to be fastenedly connected, and it can guarantee the sealing property between quiet end 5 of vacuum interrupter and the shell 1.
The end of vacuum interrupter moved end 6 is provided with positioning sleeve 7 in the utility model, and this positioning sleeve 7 is connected with the end seal of vacuum interrupter moved end 6 through sealing ring 9.The circular cowling that sealing ring is made up of one or several part; Be used for lasso or the packing ring of fixing seal effect and contact or form narrow labyrinth clearance with another lasso or packing ring; Prevent that lubricating oil from spilling and foreign object is invaded, this positioning sleeve 7 is connected what adopted with the end seal of vacuum interrupter moved end 6 be the O RunddichtringO.
The whole pole of the utility model is to adopt that outer to cover silicon rubber mould molded, and inner casting epoxy resin is made, and has adopted compound inslation, and the insulated enclosure level is improved greatly.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
