Abstract
The utility model relates to a three-phase integrated solid insulating cover. The three-phase integrated solid insulating cover is formed by epoxy resin pouring, and is based on an A, B and C-phase integrated structure. The phases are spaced via integrally poured spacing clapboards, and pole column conductors are arranged in the A, B and C phases respectively. The upper end faces of the A, B and C phases are equipped with copper inserts respectively, and a shaft base and a shaft sleeve are arranged inside the solid insulating cover. 10 bolt holes are arranged on the lower end face of the solid insulating cover, and an operation panel of the solid insulating cover is equipped with three grounding position observation windows. The beneficial effects of the utility model are that: a three-phase vacuum arc-extinguishing chamber is packaged flexibly and then is pressed in an assembled structure directly; the three-phase integrated structure enables the insulating materials among the phases to be reduced, the structure to be compact and the cost to be reduced; the three-phase integrated structure is convenient to install, and is also convenient to implement sealing measures.
Description
Technical field
The utility model relates to solid insulation ring main unit field, is mainly a kind of Three-phase common-body solid insulation cover.
Background technology
Be all three-phase split-type structural for the insulating cover of solid insulation ring main unit in the market, this structure exists installs inconvenience, and the epoxide resin material of consumption is many, and cost is high; The problems such as sealing is poor.On the other hand, current split type solid insulation cover mostly adopts the structure of the direct epoxy casting of vacuum interrupter, the pressure larger to being cast with of epoxy insulator, once there is defective item in casting process, vacuum interrupter is also scrapped thereupon, because vacuum interrupter is expensive, so can be to greatly increasing the production cost of insulating part.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide, a kind of structure is convenient installs, and is also convenient to the Three-phase common-body solid insulation cover that sealing measure is implemented.
The purpose of this utility model completes by following technical solution, this solid insulation cover adopts poured with epoxy resin to form, described solid insulation cover adopts A phase, B phase, C phase Three-phase common-body structure, adopts between phase and phase the phase partition of one cast-type to separate; This A phase, B phase, C are respectively equipped with pole conductor in mutually, and this A phase, B phase, C phase upper surface are respectively equipped with copper insert; In this solid insulation cover, be provided with axle bed and axle sleeve, the lower surface of solid insulation cover is provided with bolt hole.
As preferably, described number of bolt hole is 10.
As preferably, on the guidance panel of described solid insulation cover, offer three earthing position observation windows, these three earthing position observation windows correspond respectively to A phase, B phase, C phase.
The beneficial effects of the utility model are: three-phase vacuum interrupter is directly pressed into modular construction after adopting Soft Roll; Three-phase common-body structure can reduce insulating material between phase and phase, makes compact conformation, cost; And Three-phase common-body structure is convenient installs, and is also convenient to sealing measure and implements.

Embodiment
Below in conjunction with accompanying drawing, the utility model is done to detailed introduction: as shown in accompanying drawing 1 to 5, solid insulation cover 10 of the present utility model adopts epoxy resin 1 cast to form, described solid insulation cover 10 adopts A phase 11, B phase 12, C 13 Three-phase common-body structures mutually, adopt between phase and phase the phase partition 5 of one cast-type to separate, guarantee phase insulation; In this A phase 11, B phase 12, C phase 13, be respectively equipped with pole conductor 2, this A phase 11, B phase 12, C phase 13 upper surfaces are respectively equipped with copper insert 7; In this solid insulation cover 10, be provided with axle bed 3 and axle sleeve 6, the lower surface of solid insulation cover 10 is provided with bolt hole 4.
Vacuum interrupter rear-loading type structural design, because need not consider can damage ring vacuum interrupter in casting process, has improved the qualification rate of product greatly, and can vacuum interrupter for convenience detach.Once find that vacuum interrupter in use has the problems such as gas leakage, vacuum interrupter can be split out, again change new arc control device; Also be beneficial to producer for insulating cover stock, then according to the vacuum interrupter that fills different brands after user's request, can greatly shorten the delivery cycle, improved production efficiency.
As shown in Figure 5, described bolt hole 4 quantity are 10, can greatly reduce installation workload, and can reduce installation cost.And the split type insulating cover of three-phase, the set bolt of single-phase insulating cover is generally 10-12,30-36 altogether of three-phase, and installment work is cumbersome.
As shown in accompanying drawing 2,3, on the guidance panel 8 of described solid insulation cover 10, offer three earthing position observation windows 9, these three earthing position observation windows 9 correspond respectively to A phase 11, B phase 12, C phase 13; Can directly see that isolation knife is at ground state, meeting State Grid Corporation of China completely will have the requirement of obvious visual ground connection about earthed switch, has also guaranteed operating maintenance personnel's personal safety.
The utility model is not limited to above-mentioned execution mode; no matter do any variation in its shape or material formation; every employing structural design provided by the utility model, is all a kind of distortion of the present utility model, all should think within the utility model protection range.
