Description
Technical field
The utility model relates to a kind of transformer substation switch device, specifically is a kind of non-maintaining vacuum total management system cabinet.
Background technology
China 10kV switch cubicle great majority use air insulation or SF6 to make the loading switch cabinet of arc-extinguishing medium at present, and adopt general spring operating mechanism.Air-insulated switch cubicle, insulation distance requires high, and the cabinet size is bigger, is affected by the external environment, and the life-span is short.Make the loading switch cabinet of arc-extinguishing medium with SF6, the electric arc that in cut-offfing, produces pollutes easily and damages the electric elements in the cabinet, influences switch complete machine performance.And transmission mechanism is comparatively complicated, moving component is many, failure rate is higher.So prior art exists not enough: volume is big, complex structure, unstable properties, life-span are short.
The utility model content
The utility model technical problem to be solved is the deficiency that overcomes prior art, provide a kind of simple in structure, volume is little, the non-maintaining vacuum total management system cabinet of stable performance.
The technical scheme that the utility model adopted is: a kind of non-maintaining vacuum total management system cabinet the utility model comprises that gas tank, bus connect fixed contact, isolation knife assembly, arc control device assembly, outlet sleeve pipe, earthed switch, single spring electromagnetic operating mechanism, slide plate guiding interlock, undercarriage arrangement; Said live part is enclosed in the said gas tank; Said bus connects fixed contact and is fixedly installed on said gas tank top; Said isolation knife assembly is arranged on the right lower quadrant of said fixed contact; Said isolation knife assembly both sides are arranged on said gas tank middle and upper part branch; Said arc control device assembly is arranged on said isolation knife assembly lower left quarter, and said outlet sleeve pipe crosswise fixed is in said gas tank bottom, and said earthed switch is fixedly installed on said gas tank bottom; Said single spring electromagnetic operating mechanism is fixedly installed on the isolation knife assembly that said gas tank middle front part is controlled said arc control device assembly series connection with it interlock; Said slide plate guiding interlock is arranged at said single spring electromagnetic operating mechanism front portion, and said slide plate guider and said single spring electromagnetic operating mechanism one side can slide up and down, and said undercarriage arrangement is fixedly installed on said gas tank bottom.
Said gas tank is made up of the stainless steel bending plate more than three or three substantially, and said gas tank anterior welding header board and said gas tank welded top top board and said gas tank weld back plate assembling at the back and be welded.
Said undercarriage arrangement comprises left seat board, right seat board, sill, back shroud, ground connection cabling plate, base plate, cable slide plate, dividing plate; The two ends of said sill or be fixedly installed on said left seat board and relevant position, bottom, said right seat board side respectively near end face; Said back shroud is fixedly installed between said left seat board and the said right seat board near the relevant position, another side; Said ground connection cabling plate is arranged on said undercarriage arrangement bottom and interconnects with said sill; Said base plate connects said ground connection cabling plate; Said cable slide plate connects said base plate, and said cable slide plate slides before and after said left seat board right seat board bottom bending part is provided with U type bending groove, and said dividing plate is fixedly installed on said undercarriage arrangement napex and is fixedly connected with said right seat board with said left seat board.
The inner SF6 insulating gas of said gas tank air pressure is for waiting atmospheric pressure.
The beneficial effect of the utility model is: because the utility model is provided with the said isolation knife assembly of said arc control device assembly and the asynchronous interlock of series connection with it; The isolation switch of being controlled on the said isolation knife assembly by said single spring electromagnetic operating mechanism closes a floodgate prior to arc control device; The back is in the arc control device separating brake, and all live parts are enclosed in and are full of etc. in the stainless air chamber of atmospheric SF6 gas, adopt vacuum extinction; The SF6 gas-insulated; So break performance is good, reliability is high, electric arc does not expose in cut-offfing, and can not pollute and damage the electric elements in the cabinet.Because the electric elements in the switch cubicle open apart from little, arc voltage is low, arc energy is little, contact burning is few, so the number of times that it can cut-off rated current is higher than the switch of other type far away, the life-span is long, need not overhaul.Gas tank and underframe assembling are that independent module can combination in any be expanded, and have unified assembling interface, make things convenient for the upgrading expansion between composite module, just produce the deadline of having improved contract option with tissue.Therefore the utlity model has rational in infrastructure, simple in structure, stable performance, advantage such as the life-span is long, and is non-maintaining.

Embodiment
Like Fig. 1, shown in Figure 2; The utility model comprises that gas tank 1, bus connect fixed contact 2, isolation knife assembly 3, arc control device assembly 4, outlet sleeve pipe 5, earthed switch 6, single spring electromagnetic operating mechanism 7, slide plate guiding interlock 8, undercarriage arrangement 9; Said bus connects fixed contact 2 and is fixedly installed on said gas tank 1 top; Said isolation knife assembly 3 is arranged on the right lower quadrant that said bus connects fixed contact 2; Said isolation knife assembly 3 both sides are arranged on said gas tank 1 middle and upper part branch, and said arc control device assembly 4 is arranged on said isolation knife assembly 3 lower left quarters, because the utility model is provided with the said isolation knife assembly of said arc control device assembly and the asynchronous interlock of series connection with it; Closed a floodgate prior to arc control device by said single spring electromagnetic operating mechanism 7 control isolation switchs, the back is in the arc control device separating brake.All live parts are enclosed in and are filled in etc. in the stainless air chamber of atmospheric SF6 gas; Adopt vacuum extinction; The SF6 gas-insulated; So open apart from little, arc voltage is low, arc energy is little, contact burning is few, so the number of times that it can cut-off rated current is higher than the switch of other type far away, the life-span is long, need not overhaul; Said outlet sleeve pipe 5 crosswise fixed are in said gas tank 1 bottom; Said earthed switch 6 is fixedly installed on said gas tank 1 bottom, and said single spring electromagnetic operating mechanism 7 is fixedly installed on the isolation knife assembly 3 that said gas tank 1 middle front part is controlled said arc control device assembly 4 series connections with it interlock, and said slide plate guiding interlock 8 is arranged at said single spring electromagnetic operating mechanism 7 front portions; Said slide plate guider 8 can slide up and down with said single spring electromagnetic operating mechanism 7 one sides, and said undercarriage arrangement 9 is fixedly installed on said gas tank 1 bottom.
