Background technology
At present, electric pressure is that the outdoor high-voltage current-limiting fuse that plays isolation overcurrent protection in 10KV and above outdoor substation during for isolation circuit breakers and disconnecting link is all sealed in insulating sleeve, to play waterproof, and anti-pollution flashover, explosion-proof function.At present, the outdoor high-voltage current-limiting fuse insulating sleeve potted line dop that power engineering field is used, be cast iron materials, dop shape is as the Cup lid of a good seal, lid inner top has the O-ring seal of electro-insulating rubber material, during use, fuse core is put into insulating sleeve, at fuse metal end, put into the spring pad configuring again, spring pad plays the over effect that connects sealing draw-in gear conducting position and fuse metal end.Place after spring pad, just can fixing seal dop, by sealing draw-in gear and the alignment of insulating sleeve port, insulating sleeve port edge is just in time alignd with O-ring seal, then four fixed screws of sealing draw-in gear are tightened to the assembling process that has completed whole fuse insulating sleeve pipe.Just can be fixed on afterwards the link position needing, wherein whole sleeve pipe is that sealing draw-in gear by sleeve pipe two is connected with wire or cable end, therefore, insulating sleeve in use the sealing draw-in gear at its two ends constantly bearing the huge pulling force of wire or cable end; In addition, because insulating sleeve is always in open air, standing for a long time exposes to the weather drenches with rain, dop and its fixed screw are easy to corrosion, because the fuse of insulating sleeve inside is easily-consumed products, need often to change, this just requires frequently to open the sealing draw-in gear of insulating sleeve, is so easy to cause that dop fixed screw is twisted into two parts that problem finally causes whole insulating sleeve to scrap with dop inner sealing cushion rubber comes off etc.; Meanwhile, due to old-fashioned dop fastened by screw, dop is bearing the huge pulling force of wire or cable end simultaneously, brings serious inconvenience and increased the risk factor that operating personnel get an electric shock to the work of dismounting dop.Therefore, invent a kind of not only convenient disassembly but also good seal, the new-type potted line dop that simultaneously can extend insulating sleeve useful life is very necessary.
Summary of the invention
The purpose of this utility model, in order to overcome above-mentioned drawback, provides a kind of new-type outdoor high-voltage fuse insulating sleeve potted line dop.Realizing the technical scheme that object of the present invention takes is: a kind of new-type outdoor high-voltage fuse insulating sleeve potted line dop, it is characterized in that: sealing line card head consists of insulating sleeve seal groove, insulating sleeve dop and steady pin, described insulating sleeve seal groove is provided with the first ladder and two ladders of the second ladder, described the first ladder and the second ladder are respectively equipped with anticorona circular arc the first chamfering and the second chamfering, play the effect that prevents point discharge; On the first ladder, have and connect the first symmetrical pin clamp, relatively on insulating sleeve dop, have and connect symmetrical the second pin clamp and cable lug, wherein the round mouth edge, front of the first pin clamp and the second pin clamp one side is provided with 45 ° of chamferings, thereby facilitate the insertion of steady pin, below opposite side the first pin clamp, be provided with roof leaking mouthful, steady pin is inserted in the first pin clamp and the second pin clamp, connects insulating sleeve seal groove and insulating sleeve dop.Described insulating sleeve dop inside is provided with first waterproof platform and second waterproof platform, centre arranges porcelain sheath and high-tension fuse core, described first waterproof platform and second waterproof platform are all outward-dipping miter angle, when insulating sleeve level is installed, play and prevent that rainwater level from flowing into the effect of inside pipe casing, wherein first waterproof platform coordinates roof leaking mouth to play the effect of roof leaking; In addition, a side of insulating sleeve seal groove is provided with set bolt, and described insulating sleeve dop is provided with four anti-seal cushion rubbers, and four anti-seal cushion rubbers play waterproof, the good sealing function of antifouling, grease proofing and anti-haze.
The utility model convenient disassembly, good seal can extend insulating sleeve useful life simultaneously.
