Background technology
The utility model relates to the static contact of grounding switch structure of Cubicle Gas-Insulated Switchgear, due to more and more higher to the requirement of switch cubicle, production capacity is increasing, the reliability of product, fail safe are the basic pursuits of modern, improve static contact structure and can ensure the ampacity of the copper rod be connected with gas-filling cabinet fixed contact, tightness and the fitness with the earthed switch edge of a knife, safety and reliability when can make switchgear oepration at full load, equipment service life is longer.
Fixed contact in the past and sleeve pipe are thread contact, butterfly gasket is added with between fixed contact and casing-contact, by thread contact conduction (as shown in accompanying drawing in Figure of description 4), because contact is linear contact lay during screw threads for fastening, conductive area is seriously inadequate.Fixed contact is threaded, is contacted with inlet-outlet sleeve by elastic washer, also has following shortcoming: can not ensure fixed contact when reaching Tightening moment just vertical with sleeve pipe (as accompanying drawing in Figure of description 2 and accompanying drawing 3 shown); Can not ensure that again fixed contact can reach Tightening moment when ensureing that fixed contact is vertical, when ensureing Tightening moment, between fixed contact and sleeve pipe, contact area is only the linear contact lay between butterfly gasket, and contact area is little, easy heating, thus the generation causing dangerous accident.
Summary of the invention
The utility model provides the fixed contact product of the reliable fixation of a kind of contact area, and boss and line copper rod fixedly ensure that the perpendicularity of fixed contact, thus coordinate with earthing well.
The technical solution of the utility model is: a kind of grounding static contact of gas-insulated metal enclosed switchgear, comprise: mutual vertically disposed stator and contact blade, described contact blade one end is arranged on the front of described stator, it is characterized in that, the reverse side of described stator is vertically provided with boss, described stator is also provided with a through hole, and the through hole of described stator is bolted on sleeve pipe, in what described boss shape was coincide snap onto draw-in groove that copper rod is provided with.
A kind of preferred embodiment of the present utility model is, the tightness that described contact blade is connected with described sleeve pipe tightens extent control by bolt.
A kind of preferred embodiment of the present utility model is, described boss can be clamped by described draw-in groove, and described fixed contact can not rotate along described copper rod axis.
A kind of preferred embodiment of the present utility model is, described fixed contact is all electrically connected with described copper rod and described sleeve pipe.
A kind of preferred embodiment of the present utility model is that described contact blade is vertical with the earthing edge of a knife.
A kind of preferred embodiment of the present utility model is that the seamed edge of described contact blade is provided with chamfering or seamed edge is designed to arcuate structure.
A kind of preferred embodiment of the present utility model is, described copper rod axes normal is in described casing axis.
a kind of preferred embodiment of the present utility model is, described contact blade, described stator and described boss three are the integrative-structure of conduction.
The beneficial effect that the utility model reaches: eliminate butterfly gasket structure, ensure the ampacity of the copper rod be connected with gas-filling cabinet fixed contact, tightness and the fitness with the earthed switch edge of a knife, safety and reliability when can make switchgear oepration at full load, equipment service life is longer; Boss and copper rod fixedly ensure that the perpendicularity of fixed contact, thus coordinate with earthing well; Choosing is screwed fixed contact and sleeve pipe, and can make fixed contact fixation, its structure is simple, compact firm, convenient and practical.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in figs 1-9, a kind of grounding static contact of gas-insulated metal enclosed switchgear, comprise: mutual vertically disposed stator and contact blade, contact blade one end is arranged on the front of stator, the reverse side of stator is vertically provided with boss, stator is also provided with a through hole, and the through hole of stator is bolted on sleeve pipe, in what boss shape was coincide snap onto draw-in groove that copper rod is provided with.The technical solution of the utility model can ensure the ampacity of the copper rod be connected with gas-filling cabinet fixed contact, tightness and the fitness with the earthed switch edge of a knife, and safety and reliability when can make switchgear oepration at full load, equipment service life is longer.
The tightness that contact blade is connected with sleeve pipe tightens extent control by bolt, there will not be in prior art, tightens the phenomenon that degree and perpendicularity cannot be in harmonious proportion.Adopt the connected mode of bolt to too increase the contact area of circuit, significantly increase ampacity, there will not be the potential safety hazards such as overheated.
Boss can be clamped by draw-in groove, and fixed contact can not rotate along copper rod axis, this makes it possible to ensure that fixed contact can not rotate on copper rod, and the perpendicularity between fixed contact and earthing also can be guaranteed.Fixed contact is all electrically connected with copper rod and sleeve pipe, and copper rod axes normal is in casing axis.Contact blade is vertical with the earthing edge of a knife, and the seamed edge of contact blade is provided with chamfering or seamed edge is designed to arcuate structure, and this kind of technical scheme can effectively reduce even avoids the phenomenon of point discharge to occur.
Contact blade, stator and boss three are the integrative-structure of conduction, are conducive to the electric conductivity improving fixed contact like this, reduce caloric value.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection range of the present utility model.
