Abstract
The invention discloses an anti-crack high-voltage contact box, which comprises an insulated box body (1) with an open upper end. A fixed contact wiring flange (2) is arranged at the internal lower part of the insulated box body (1). An opening (3) which is used for connecting a wire with the fixed contact wiring flange (2) is arranged on the side surface of the lower part of the insulated box body (1). A process hole (5) is arranged below the bottom (4) of the insulated box body (1). The bottom of the process hole (5) consists of a peripheral surface (6) and a central surface (7) which are connected with each other. The thickness of the bottom (4) of the insulated box body (1) is 92cm. The peripheral surface (6) and the central surface (7) at the bottom of the process hole (5) are circular arc curved surfaces and are in smooth transition connection with each other. The anti-crack high-voltage contact box has the advantages that the stress is dispersed, the strength is increased, the epoxy resin is prevented from being cracked, the service life of the product is prolonged, the situations of insulation aging breakdown, short circuit to the ground, and the like, caused by insulation damages, can be avoided, and the reliable operation of the grid is ensured.
Description
Technical field
The present invention relates to a kind of high-voltage contact box, especially a kind of box body that prevents to insulate ftractures, increases the service life, can guarantee the anti-cracking high-voltage contact box of electrical network reliability service.
Background technology
The high-voltage contact box is the device that is installed in the high-tension switch cabinet, its structure is to be provided with the insulation box body that forms upper end open with poured with epoxy resin, the bottom is provided with and is used for the fixed contact and the line flange that join with handcart moving contact in the insulation box body, has the opening that is used for fixed contact wiring flange line in insulation box body lower side.For conservation and easy to process, below the bottom of insulation box body, also have fabrication hole, the bottom of fabrication hole is joined by peripheral surface and median plane, has advantages such as convenient installation, maintenance.But, because existing contact box bottom thickness only is 70cm, peripheral surface is that plane, median plane are semicircle sphere in addition, tangible boundary line is arranged between peripheral surface and the median plane, in production or the use, different because of the shrinkage ratio of epoxy resin and metal, be easy to cause place, boundary line cracking, can't guarantee that electrical network normally moves.
Summary of the invention
The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, provides a kind of box body that prevents to insulate to ftracture, increase the service life, can guarantee the anti-cracking high-voltage contact box of electrical network reliability service.
Technical solution of the present invention is: a kind of anti-cracking high-voltage contact box, the insulation box body that upper end open is arranged, the bottom is provided with fixed contact wiring flange in the insulation box body, have the opening that is used for the wiring of fixed contact wiring flange in insulation box body lower side, below the bottom of insulation box body fabrication hole is arranged, the bottom of fabrication hole is joined by peripheral surface and median plane and forms, it is characterized in that: the bottom thickness of described insulation box body is 92cm, and the peripheral surface of described fabrication hole bottom and median plane are circular arc camber and rounding off connection.
The present invention has increased the thickness of insulation box body bottom and the peripheral surface and the median plane of fabrication hole bottom is circular arc camber and rounding off connection, stress is disperseed, intensity increases, avoid the epoxy resin cracking, prolonged the useful life of product, avoid having guaranteed the reliability service of electrical network because of phenomenons such as insulation breakdown that insulation damages causes, shorted to earths.
Description of drawings
