Described link is a kind of U-shaped link, and two ends are provided with circular hole, and the circular hole that described screw passes two ends is fixed on link on the top cover, and the user can be conveniently with insulation bolt and device separates by the pulling to link.
Described top cover is a kind of circular metal lid, and crown cap is with annular projection outward, and there is the screw hole of two symmetries the annular projection upper end, and there is screw thread the annular projection lower end.
The function of described top cover be its inside by special coupling agent and the rubber semi-conductive layer is bonding is integral, the stressed carrier as rubber part plays shielding action simultaneously.
Described adapter sleeve is a kind of metal sleeve, and its top is provided with draw-in groove, and afterbody is provided with internal thread, and described afterbody is connected with top cover by internal thread.
Described rubber semi-conductive layer is a kind of serum cap with semiconductive characteristic, center of top has tubular protrusion, its upper end outer surface and above-mentioned top cover in the course of processing carry out bonding, and inner surface and rubber insulation carry out bonding, and its effect is the electric outlet side of even equipment electric field.
Described rubber insulation is a kind of serum cap with insulation property, and center of top has tubular protrusion, and it is bonded together in course of processing outer surface and rubber semi-conductive layer, and its effect is increase equipment outlet side dielectric strength.
The beneficial effects of the utility model are that the insulated enclosure for distribution bypass cable operation cable end piece joint or equipment outlet side has increased outlet side electric insulation intensity, avoids equipment discharge over the ground in the process of withstand voltage test, makes its fail safe higher.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is link (1) structural representation;
Fig. 3 is that top cover (3) partly cuts open the structure front view;
Fig. 4 is top cover (3) structure vertical view;
Fig. 5 is adapter sleeve (4) structural representation;
Fig. 6 is rubber semi-conductive layer (5), rubber insulation (6) combination elevation cross-sectional view.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, a kind of 10kV bypass cable implement special isolation bolt, comprise link 1, screw 2, top cover 3, adapter sleeve 4, rubber semi-conductive layer 5 and rubber insulation 6, adapter sleeve 4 is threaded with top cover 3, link 1 is connected with top cover 3 by screw 2.
Rubber semi-conductive layer 5 sticks on the outside of rubber insulation 6, and rubber semi-conductive layer 5 tops are connected with top cover 3, and adapter sleeve 4 and top cover 3 are coated on inside by being threaded with rubber semi-conductive layer 5 half, and link 1 is fixed on top cover 3 both sides by screw 2.
Rubber semi-conductive layer 5 is a kind of serum caps with semiconductive characteristic, center of top has tubular protrusion, its upper end outer surface and end cap 3 in the course of processing carry out bonding, and inner surface and rubber insulation 6 carry out bonding, and its function is: the even electric outlet side of equipment electric field.
Operation principle of the present utility model is:
This insulation bolt cleans rubber insulation 6 inner surfaces earlier, above being evenly coated in the insulation silicone grease then in use, operating personnel grasp link 1 then, and the bolt aligning equipment that should insulate is electric to go out line interface, inserts gently, after metal sleeve front end draw-in groove enters assigned address, confirm to install.At this moment insulating barrier part of the present utility model has increased insulation distance between the two with separating between the electric outlet side of equipment and the equipment ground, when guaranteeing that equipment boosts, leading-out terminal can not occur and discharge over the ground.The rubber semi-conductive layer 5 of the utility model outside is connected with equipment ground with the metal part in addition, has avoided the utility model outer surface big induced voltage to occur, causes insulation breakdown.
