Abstract
The utility model discloses a power line suspension insulator rack which is provided with a rear flange [1] and an end socket [8] at the front end. The power line suspension insulator rack is characterized in that an epoxy resin glass fiber tube [4] which is cured on the end socket and the rear flange is arranged between the rear flange and the end socket; an insulation protective layer is arranged outside the epoxy resin glass fiber tube; the rear part of the end socket is provided with an anchor ear pad [5]; and a through hole through the anchor ear pad penetrates through the anchor ear pad and a ring bolt [7] of the epoxy resin glass fiber tube when being fixed by a nut [6]. The suspension truss of the pylon and the line pole of the power transmission line in the steel structure is transformed into the hanging rack made of epoxy resin glass fiber materials, thereby greatly enhancing the insulation degree; and the protective layer on the outer surface of the epoxy resin glass fiber greatly enhances the contamination flashover resistance of the power transmission line, thereby reducing the height of the pylon in the power transmission line and having obvious saving effect.
Description
Technical field
The utility model belongs to the electric power power transmission and transforming equipment, and definite saying is a kind of power circuit suspension insulator support.
Background technology
Insulator, particularly suspension insulator on the present widely used electric power power transmission and transformation line, its upper end all is the end of the steel truss of the iron tower that is suspended on the electric power power transmission and transformation line, line bar, this steel truss is commonly called as: cross-arm.Because steelframe do not have insulating properties, thus the circuit of high voltage power transmission and transforming for solve to high pressure over the ground, problem such as pollution flashover, built on stilts distance is more and more higher, but also will regularly carry out the operation of maintenance rationally such as antirust, scrubbing.Designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model puts forward in order to overcome the problems such as pollution flashover that exist between present power circuit insulator and iron tower and the line bar.A kind of power circuit suspension insulator support promptly is provided.
Technical solution of the present utility model is to realize like this, this kind power circuit suspension insulator support, it has the end socket of rear flange and front end, between rear flange and the end socket be an epoxy resin fiberglass pipe that is solidificated on end socket and the rear flange, has one deck insulating protective layer in the outside of this epoxy resin fiberglass pipe, have an anchor ear pad at the rear portion of end socket, fixing the eye bolt that passes anchor ear pad and epoxy resin fiberglass pipe by nut by the through hole of this anchor ear pad.
Beneficial technical effects of the present utility model is: the support that has been become the epoxy resin fiberglass material of this device from the suspension truss of the iron tower of electric power power transmission and transformation line or line bar by the truss of the steel construction in past, insulation degree is therebetween strengthened greatly, add the overcoat of the outer surface of epoxy resin fiberglass, improved the ability that electric power power transmission and transformation line anti-soil dodges greatly, therefore can lower the height of iron tower for power transmission and transformation line, the effect of its saving also is conspicuous.
Description of drawings
Accompanying drawing 1 is a structural profile schematic views of the present utility model, and accompanying drawing 2 is partial cutaway schematic of silicon rubber overcoat.Sequence number in the accompanying drawings is described as: 1, rear flange, 2, through hole, 3, silastic-layer, 4, the epoxy resin fiberglass pipe, 5, the anchor ear pad, 6, nut, 7, eye bolt, 8, end socket.
Embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this power circuit suspension insulator support, it has the end socket [8] of rear flange [1] and front end, it is characterized in that between rear flange and the end socket being an epoxy resin fiberglass pipe [4] that is solidificated on end socket and the rear flange, has one deck insulating protective layer in the outside of this epoxy resin fiberglass pipe, have an anchor ear pad [5] at the rear portion of end socket, fixing the eye bolt [7] that passes anchor ear pad and epoxy resin fiberglass pipe by nut [6] by the through hole of this anchor ear pad.Said insulating protective layer is silastic-layer [3].Further, said silastic-layer [3] is the silastic-layer with full skirt, and umbrella skirt construction also can adopt the version of contour full skirt as shown in Figure 2.Said epoxy resin fiberglass pipe [4] is the cone of a frustum of a cone or the frustum of a pyramid.Said end socket [8] is an one with anchor ear pad [5].The center of said end socket [8] has screwed hole.
It needs to be noted, when being revolved to turn 90 degrees, the anchor ear pad becomes and ground level, lock with an eye bolt of assembling [7] in the screwed hole of centre on the end socket [8] and with nut [6], structure then of the present utility model has just become the support of a kind of right angle strain insulator, like this, just greatly increased the scope of application of the present utility model.Similarly, the both sides of anchor ear pad are the fit on eye bolt all, and turn 90 degrees according to revolving in the accompanying drawing 1, then can be used as common strain insulator support.This shows to the utlity model has significant unobviousness, possess good serviceability simultaneously.
During use, the iron tower on the through hole [2] on the rear flange [1] and the power transmission and transformation line or the preformed hole on the line bar are cooperated fixing, suspension insulator is hung on according to the rules in the annular hanging hole of eye bolt [7] and get final product.
