As a kind of preferred structure of the present utility model, described shielding gold utensil lateral surface is plane, is hemispherical inside it, and the inner side of described fixing gold utensil is also hemispherical, and the groove on described fixing gold utensil is rounded to be uniformly distributed.
Insulation bolt in the utility model is injection molded into integral structure by insulating body, shielding gold utensil and fixing gold utensil, one end is extremely connected with high-tension electricity through braking gold utensil by shielding gold utensil, the other end is by fixing gold utensil ground connection, the outside of insulation bolt is fixed by compression gold utensil and baffle plate, and spring is provided with between insulation bolt and compression gold utensil, close contact between each parts can be guaranteed, thus control electric fields uniform distribution, avoid the test effect affecting equipment because inner air produces electric discharge phenomena.
In addition, be divided into two because breeches joint can realize a circuit, in two line outlets of breeches joint, insulation bolt is arranged on one of them line outlet by the utility model, and another line outlet connection line can realize the operation in advance of single line.Treat that another line arrangement is complete, insulation bolt can be removed, Article 2 circuit is installed.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the structural representation of insulation bolt.
Fig. 3 is the right view of Fig. 2.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise the epoxy bushing being positioned at GIS terminal, the extreme and earth terminal of high-tension electricity is set respectively in epoxy bushing, also comprises insulation bolt, braking gold utensil 1, compression gold utensil 2 and baffle plate 3.In the end of epoxy bushing, set gradually braking gold utensil 1, insulation bolt, compression gold utensil 2 and baffle plate 3 from inside to outside along axis, the usual outer panel of baffle plate 3 flushes with the outer face of epoxy bushing.Described braking gold utensil 1 is disc block structure, usually be made up of aluminium alloy, the axes normal of its card and epoxy bushing, braking gold utensil 1 is extreme near the high-tension electricity of epoxy bushing inside, braking gold utensil 1 can be used for the accurate location of insulation bolt, prevents the occurrence positions skew under long-term extruding of insulation bolt.Described insulation bolt comprises insulating body 4, shielding gold utensil 5 and fixing gold utensil 6, insulating body 4 normally electro-insulating rubber is made, insulating body 4 is taper mesa-shaped, and be namely the taper that one end diameter is large, one end diameter is little, its end diameter is corresponding to the diameter of braking gold utensil 1.Shielding gold utensil 5 and fixing gold utensil 6, all in cylindrical-shaped structure, are made by aluminum alloy materials, and shielding gold utensil 5 embeds insulating body 4 smaller diameter end, its outer surface and insulating body 4 end face, and shielding gold utensil 5 is connected with braking gold utensil 1 by bolt.Fixing gold utensil 6 embeds insulating body 4 larger diameter end and is connected with earth terminal, and its outer surface flushes with insulating body 4 other end, namely with major diameter end face.On the outer surface of fixing gold utensil 6, also distribution arranges cylinder shape groove, is provided with spring 7 in groove.Insulating body 4, shielding gold utensil 5 and fixing gold utensil 6 are injection molded into integral structure by electro-insulating rubber.Described compression gold utensil 2 is the barrel-shaped of horizontally set, the axis of compression gold utensil 2 and the axis coaxle of insulate bolt and epoxy bushing, the bottom of compression gold utensil 2 and base plate are close proximity to the outside of fixing gold utensil 6 and spring 7, be bolted between base plate and fixing gold utensil 6, the pressure between compression gold utensil 2 and spring 7 is regulated by the screw-in depth arranging this bolt, thus adjustable brake gold utensil 1, contact dynamics between insulation bolt and Compress Spring 7, avoid occurring space between them, prevent the electric discharge phenomena because air causes, effective contact at insulation bolt two ends can also be made simultaneously.Baffle plate 3 abuts against the outside of compression gold utensil 2, and baffle plate 3 is connected with epoxy bushing by bolt.
Because the insulation bolt in the utility model is injection molded into integral structure by insulating body 4, shielding gold utensil 5 and fixing gold utensil 6, one end is extremely connected with high-tension electricity through braking gold utensil 1 by shielding gold utensil 5, the other end is by fixing gold utensil 6 ground connection, the outside of insulation bolt is fixed by compression gold utensil 2 and baffle plate 3, and spring 7 is provided with between insulation bolt and compression gold utensil 2, close contact between each parts can be guaranteed, thus control electric fields uniform distribution, avoid the test effect affecting equipment because inner air produces electric discharge phenomena.
As a kind of preferred structure of the present utility model, described shielding gold utensil 5 lateral surface is plane, be hemispherical inside it, the inner side of described fixing gold utensil 6 is also hemispherical, see Fig. 2, two hemisphere faces are oppositely arranged and are isolated by insulating body 4, and the groove on described fixing gold utensil 6 is rounded to be uniformly distributed, see Fig. 3, this structure can make Electric Field Distribution herein evenly.
The utility model has can avoid GIS terminal epoxy bushing to produce electric discharge, improves the feature of security performance.
