Description
Technical field
The utility model relates to a kind of plateau type high-tension switch cabinet, particularly relates to a kind of plateau type high-tension switch cabinet wall bushing.
Background technology
High-tension switch cabinet refers to for electric power system generating, transmission of electricity, distribution, electric energy conversion and the electric equipment products playing the effects such as break-make, control or protection in consuming.
Along with the enforcement of national strategy to develop western regions, electric power network at different levels is constantly expanded and is extended, particularly height above sea level 1500-3500m area, and aboundresources, economic development is rapid, thus also grows with each passing day to the demand of high-tension switch cabinet.But, be used in the high-tension switch cabinet of High aititude region compared with ordinary high pressure switch cubicle, in " the height above sea level correction " of technical parameter, there is more difference in the direction such as selection, cabinet body structure design, layout of components and parts, insulating part, and some is the problem being difficult to capture.Such as, it is short to there is creepage distance in high altitude localities use in the wall bushing that existing ordinary high pressure switch cubicle adopts, and causes its useful life short, increases maintenance cost, thus, is badly in need of solving.
Utility model content
The purpose of this utility model is for the problems referred to above, a kind of plateau type high-tension switch cabinet wall bushing is provided, it is short to there is creepage distance in high altitude localities use in the wall bushing adopted to solve existing logical high-tension switch cabinet, causes its useful life short, the problem that maintenance cost is large.
The purpose of this utility model is achieved through the following technical solutions:
A kind of plateau type high-tension switch cabinet wall bushing, comprise wall bushing body, the outer wall of described wall bushing body is provided with insulation protruding, and the inside of wall bushing body is provided with at least 2 inner skirt, at least 2 described inner skirt radially distribute, and be connected, and be provided with gap between adjacent inner skirt between adjacent inner skirt, the inner skirt that described wall bushing body is adjacent is connected, and is provided with gap between the inner skirt that is adjacent of wall bushing body.
As preferred version of the present utility model, the described protruding projection that insulate in first of wall bushing body one end spaced apart, the second insulation projection and the second insulation projection, the 3rd in the wall bushing body other end spaced apart of comprising that insulate insulate protruding, the external diameter of described first insulation projection is greater than the external diameter of the second insulation projection, and the external diameter of described second insulation projection is greater than the protruding external diameter of the 3rd insulation.
As preferred version of the present utility model, the inside of described wall bushing body is provided with 2 inner skirt.
As preferred version of the present utility model, described wall bushing body is made up of epoxide resin material.
The beneficial effects of the utility model are, described plateau type high-tension switch cabinet wall bushing is protruding by arranging the different insulation of height, and at least 2 inner skirt are set in wall bushing body interior, increase effectively creepage distance, high altitude localities can be applicable to, extend the useful life of wall bushing body, reduce maintenance cost, structure is simple, be easy to realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model plateau type high-tension switch cabinet wall bushing.
In figure:
1, wall bushing body; 2, the first insulation is protruding; 3, the second insulation is protruding; 4, the 3rd insulation is protruding; 5, the first inner skirt; 6, the second inner skirt.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.Be understandable that, embodiment described herein only for explaining the utility model, but not to restriction of the present utility model.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of the utility model plateau type high-tension switch cabinet wall bushing.
In the present embodiment, a kind of plateau type high-tension switch cabinet wall bushing, comprise the wall bushing body 1 be made up of epoxide resin material, the outer wall of described wall bushing body 1 is provided with insulation protruding, described insulation projection comprises spaced apart in the first insulation protruding 2 of wall bushing body 1 left end, second insulation protruding 3 and spaced apart in the second insulation protruding 3 of wall bushing body 1 right-hand member, 3rd insulation protruding 4, the external diameter of described first insulation protruding 2 is greater than the external diameter of the second insulation projection 3, the external diameter of described second insulation protruding 3 is greater than the external diameter of the 3rd insulation protruding 4, the inside of described wall bushing body 1 is provided with the first inner skirt 5, second inner skirt 6, described first inner skirt 5, second inner skirt 6 radially distributes, and the external diameter of the first inner skirt 5 is greater than the external diameter of the second inner skirt 6, be connected between first inner skirt 5 with the second inner skirt 6, and be provided with gap between the first inner skirt 5 and the second inner skirt 6, described wall bushing body 1 is connected with the first inner skirt 5, and be provided with gap between wall bushing body 1 and the first inner skirt 5.
The utility model, without the need to increasing wall bushing body 1 size, by adopting the different insulation projection 2,3,4 of height and setting up inner skirt 5,6, substantially increases creepage distance, can meet High aititude requirement in the useful space.
Above embodiment has just set forth general principle of the present utility model and characteristic; the utility model does not limit by above-described embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various change and change, and these changes and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
