Abstract
The utility model discloses an anti-cracking high-voltage contact box, which is provided with an insulating box body (1) with upper end open. A static contact connecting flange (2) is arranged on the inner lower portion of the insulating box body (1), an opening (3) used for being connected with the static contact connecting flange (2) is arranged on the side of the lower portion of the insulating box body (1), an access hole (5) is arranged at a bottom (4) of the insulating box body (1), the bottom of the access hole (5) consists of a peripheral surface (6) and a central surface (7) in a jointed manner, the bottom (4) of the insulating box body (1) is 92cm in thickness, and both the peripheral surface (6) and the central surface (7) of the bottom of the access hole (5) are curved surfaces and in smooth transitional connection. The anti-cracking high-voltage contact box has the advantages that stress is dispersed, strength is increased, cracking of epoxy resin is avoided, service life of the high-voltage contact box is prolonged, breakdown caused by insulation ageing, ground short-circuit and the like due to damage to insulation are avoided, and accordingly reliable running of a power grid is guaranteed.
Description
Technical field
The utility model relates to a kind of high-voltage contact box, and 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 utility model 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 utility model 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 utility model 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
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: the insulation box body 1 of the upper end open that useful poured with epoxy resin forms, the bottom is provided with fixed contact wiring flange 2 in insulation box body 1, have the opening 3 that is used for 2 wiring of fixed contact wiring flange in insulation box body 1 lower side, below the bottom 4 of insulation box body 1 fabrication hole 5 is arranged, bottom 4 thickness of insulation box body 1 are 92cm, and the peripheral surface 6 of described fabrication hole 5 bottoms and median plane 7 are circular arc camber and rounding off connects.
