Abstract
The utility model provides a three-phase with one box basin-type insulator which is applied to the technical field of SF6 gas-insulated metal-enclosed combined electrical apparatus. The three-phase with one box basin-type insulator comprises an aluminium flange, a conductor, a equalizing ring and an epoxy resin; the epoxy resin is arranged between the aluminium flange and the conductor; the equalizing ring is connected in series with the aluminium flange; the whole of the equalizing ring and communicating parts of the equalizing ring and the aluminium flange are arranged in the epoxy resin. The three-phase with one box basin-type insulator has the advantages of changing the distribution of electric fields of the three-phase with one box basin-type insulator and reducing the cracking possibility of the whole three-phase with one box basin-type insulator.
Description
Technical field
The utility model relates to the device of the gas-insulated metal-enclosed combined electrical apparatus technical field of a kind of SF6 of being applied to, specifically is a kind of Threephase common-box disc insulator.
Background technology
In the gas-insulated metal-enclosed combined electrical apparatus of SF6, conductor is sealed in metal shell inside, and the insulation between conductor and the metal shell realizes by SF6 gas, Threephase common-box disc insulator.The Threephase common-box disc insulator divides two types, a kind of is with holes, another kind is not with holes, they form by the epoxy resin casting of high-quality, conductor casts in the epoxy resin, two kinds of disc insulators all have insulation function and supportive conductors effect, the effect that also has the separation air chamber not with holes.
Find through retrieval prior art, Chinese patent publication number CN201327746 has put down in writing " a kind of Threephase common-box disc insulator ", no aluminium flange in this technology, the stress that the external world applies directly acts on insulating body, just might cause breaking of whole disc insulator.
The utility model content
The utility model provides a kind of Threephase common-box disc insulator at the prior art above shortcomings, makes it reduce the possibility that whole disc insulator breaks by simple structure.
The utility model is achieved through the following technical solutions, the utility model comprises: aluminium flange, conductor, grading ring and epoxy resin, wherein: epoxy resin is between aluminium flange and conductor, grading ring and aluminium flange are connected in series, and connection place of grading ring integral body and grading ring and aluminium flange all is positioned at epoxy resin inside.
Described disc insulator conductor inside amounts to three.
Described aluminium flange is a circular ring.
Described grading ring is a circular ring, and described grading ring is provided with three ring teeth to connect the aluminium flange.
Described grading ring is a circular ring, and described epoxy resin is provided with three through holes, and this through hole is used to be communicated with the air chamber at disc insulator two ends.
Grading ring and aluminium flange are exactly same current potential in the utility model, if the aluminium flange ground connection also just corresponding ground connection of grading ring so.The grading ring of ground connection plays excellent shielding effect to the air gap between aluminium flange and the epoxy resin, can improve the Electric Field Distribution of disc insulator and reduce the breakdown possibility of disc insulator, the aluminium flange of circular ring has also strengthened the mechanical strength of whole disc insulator.

Embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
As Fig. 1, Fig. 3 and shown in Figure 4, present embodiment comprises: aluminium flange 1, conductor 2, grading ring 3 and epoxy resin 4, wherein: epoxy resin 4 is between aluminium flange 1 and conductor 2, grading ring 3 is connected in series with aluminium flange 1, and connection place of grading ring 3 integral body and grading ring 3 and aluminium flange 1 all is positioned at epoxy resin 4 inside.
Described conductor 2 amounts to three, and all casts in the epoxy resin 4.
As shown in Figure 3, described grading ring 3 is an aluminum filled circles ring-type structure, is provided with three ring teeth on grading ring, is connected with aluminium flange 1 by the ring tooth.Circle-shaped symmetrical structure electric field shielding is effective, and solid construction can avoid air to sneak into epoxy resin and reduce its dielectric strength.
As shown in Figure 4, described aluminium flange 1 is a circular ring.
In the present embodiment:
Described aluminium flange 1 structure, can balance to the stress that disc insulator applies, reduce the possibility that whole disc insulator breaks.
Described grading ring plays shielding action to the air gap between aluminium flange 1 and the epoxy resin 4, has improved the Electric Field Distribution of disc insulator,
As shown in Figure 2, in the present embodiment, described epoxy resin 4 is provided with three through holes 5.This through hole 5 is used to be communicated with the air chamber at disc insulator two ends.
