Abstract
The utility model relates to a fuse, concretely relates to outdoor type PT fuse of 35kV. It overlaps, sets up the fuse -element pipe in insulating cover and be fixed in insulating the taking over a business of both ends of overlapping including insulating, insulating cover level is horizontal in post insulators's top, insulating cover is on being fixed in post insulators through the fixing clip, the fixing clip is from the locking -type fixing clip. The utility model discloses a from the installation of the insulating cover of locking -type fixing clip realization with post insulators, this presss from both sides structure for traditional double cassette and has the convenient advantage of dismantlement to can not cause unable the dismantlement because of the bolt corrosion.
Description
Technical field
The utility model relates to fuse, is specifically related to a kind of 35kV outdoor type PT fuse.
Background technology
Fuse is widely used in high and low voltage electric distribution system, and it is generally the top being horizontally placed on post insulator when mounted.At present, fuse and post insulator are fixed by two clips, is fastened by bolts between two clips.There is the defect of installing inconvenience in this conventional mounting structure, it needs frequent assembling-disassembling bolt when installation, dismounting, and the easy corrosion of bolt, cause dismounting difficulty.
Fuse is primarily of insulating case, melt pipe and end cap composition, and melt pipe is located in insulating case, and melt pipe is closed by the two ends that end cap is screwed in insulating case.The fuse of this structure also exists melt pipe and changes difficult and that wiring is inconvenient problem.
Summary of the invention
The utility model, for solving the problem, have developed a kind of 35kV outdoor type PT fuse.
The utility model is achieved by the following technical solution:
A kind of 35kV outdoor type PT fuse, include insulating case, be arranged at the melt pipe in insulating case and be fixed on taking over a business of insulating case two ends, described insulating case level is horizontally placed on the top of post insulator, it is characterized in that: described insulating case schedules on post insulator by fixing fixing, described fixing card is the fixing card of self-locking, it includes wild card and Nei Ka, described wild card is " U " shape structure, wild card both sides are elastic sheet metal, described interior card is jump ring clamping structure, described interior fixing is between two elastic sheet metals of wild card, the insulating case bayonet socket being close to elastic sheet metal is arranged at the top of described interior card, described fixing card bottom has through interior, the screw rod of wild card, the traversing through end cover of described screw rod has holddown spring and passes through nut, in described, wild card is fixed on post insulator by screw.
Described take over a business with insulating case for being threaded, described in take over a business be provided with spring between the melt pipe in insulating case, be provided with spring fixed clip sheet between described spring and melt pipe, described spring fixed clip sheet is provided with the recess of fixing spring.
Described insulating case two ends take over a business to be provided with connector lug, and wherein the connector lug of side is fixing, and the connector lug of opposite side is rotating.
The utility model adopts fixing card to realize the installation of insulating case and post insulator, and this has the advantage of convenient disassembly relative to traditional double card clamping structure, and cannot can not dismantle because bolt corrosion causes.In addition, the utility model is also convenient to wiring and is changed melt pipe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the conventional mounting structure figure of insulating case and post insulator.
Fig. 2 is the mounting structure figure of insulating case and post insulator in the utility model.
Fig. 3 is the structural representation of fixing card.
Fig. 4 is A portion enlarged drawing.
In figure, 1 insulating case, 2 post insulators, 3 fixing cards, 4 are taken over a business, cards, 7 wild cards, 8 screw rods, 9 nuts, 10 holddown springs, 11 screws, 12 melt pipes, 13 spring fixed clip sheets, 14 springs, 15 insulating case bayonet sockets, 16 cambered surfaces lead mouth in 5 connector lugs, 6.
Embodiment
Accompanying drawing 2,3 is a kind of specific embodiment of the present utility model.It includes insulating case 1, what be arranged at the melt pipe 12 in insulating case and be fixed on insulating case two ends takes over a business 4, described insulating case level is horizontally placed on the top of post insulator 2, it is characterized in that: described insulating case is fixed on post insulator by fixing card 3, described fixing card is the fixing card of self-locking, it includes wild card 7 and Nei Ka 6, described wild card is " U " shape structure, wild card both sides are elastic sheet metal, described interior card is jump ring clamping structure, described interior fixing is between two elastic sheet metals of wild card, the insulating case bayonet socket 15 being close to elastic sheet metal is arranged at the top of described interior card, described fixing card bottom has through interior, the screw rod 8 of wild card, the traversing through end cover of described screw rod is had holddown spring 10 and is screwed by nut 9, in described, wild card is fixed on post insulator by screw 11.
Further, the insulating case bayonet socket upper end of described interior card is provided with cambered surface and leads mouth 16.Insulating case conveniently can be pressed into insulating case bayonet socket by the design that cambered surface leads mouth.
By tightening nut 9, make holddown spring 10 be in compressive state, wild card 7 two-side elastic sheet metal is stressed and compress the interior insulating case bayonet socket 15 blocked; When installing insulating overlaps, only need press insulating case and just it can be led mouth 16 by cambered surface and snap in insulating case bayonet socket, and reliably fix; When insulating case pulled down by needs, directly insulating case can be led mouth by the cambered surface of interior card upper end and take out; Whole installation, unloading process are simple and convenient, without the need to repeated disassembled and assembled bolt, solve traditional structure easily because bolt corrosion causes dismantling the problem of difficulty.
Further, described in take over a business with insulating case for being threaded, described in take over a business be provided with spring 14 between the melt pipe in insulating case, be provided with spring fixed clip sheet 13 between described spring and melt pipe, described spring fixed clip sheet is provided with the recess of fixing spring.Only need screw off when changing melt pipe.
Further, described insulating case two ends take over a business to be provided with connector lug 5, and wherein the connector lug of side is fixing, and the connector lug of opposite side is rotating.Turnable connector lug can more convenient wiring.
Further, rotating connector lug 5 with take over a business 4 and be threaded connection.
