Abstract
The utility model discloses a knife-switch self-locking type outdoor AC three-phase linked high-voltage disconnector. A knife-switch linking mechanism comprises a couple axle, a couple axle connecting lever and an insulating pull bar of the knife-switch. A self-locking stopper is fixed on a pedestal and on the rotating path of the couple axle connecting lever, and is so structured that when the couple axle drives the knife-switch to be switched to a limiting position, the lower hinge point of the insulating pull bar is limited at a self-locking limiting position. The self-locking limiting position allows the lower hinge point of the insulating pull bar to exceed and deviate away the upper and lower hinge points of the insulating pull bar when the knife-switch is switched on, and being on a same straight line with the couple axle and not exceed the vertical plane where the axis of the couple axle lies. The knife-switch self-locking type outdoor AC three-phase linked high-voltage disconnector is simple in structure, prevents misoperation of the knife-switch and ensures the normal and safe switching on of the knife-switch.
Description
Technical field
The utility model relates to the high-tension electricity fling-cut switch of power circuit---outdoor three-phase linkage high voltage isolator.
Background technology
In electric power system power transmission and transforming equipment, three-phase linkage high-voltage isolating switch has completed synchronous point, has closed the vital task of conversion three-phase power circuit and assurance maintenance safety.Vertical unlocking divides, closes in the three-phase linkage high-voltage isolating switch of master cock disconnecting link, and the linkage driving mechanism of three-phase disconnecting link comprises that rotation is installed on the universal driving shaft of base, and universal driving shaft San road connecting lever is connected with three insulated tension poles at three-phase disconnecting link middle part respectively.For avoiding the disconnecting link misoperation of opening, in three-phase linkage high-voltage isolating switch, be provided with self-locking spring device, it reaches self-locking object by the Compress Spring between additional connecting lever and the base arranging on universal driving shaft.Because the elastic force of spring can or tiredly be difficult to reach reliable self-locking purpose of design because of the decay of self.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of simple structure, the reliable self-locking type outdoor AC of self-locking state three-phase linkage high-voltage isolating switch.The disconnecting link self-locking type outdoor AC three-phase linkage high-voltage isolating switch technical scheme that the utility model provides, its main technical content is: a kind of disconnecting link self-locking type outdoor AC three-phase linkage high-voltage isolating switch, disconnecting link link gear is wherein by universal driving shaft, the insulated tension pole composition of universal driving shaft connecting lever and disconnecting link, Lian Dong Zhou Transverse is rotatably installed on base to running through, on universal driving shaft, the position corresponding with three-phase disconnecting link is provided with three road connecting levers, the insulated tension pole of three disconnecting links is connected between corresponding connecting lever and disconnecting link, on base, be fixed with self-locking limit device, described self-locking limit device is fixed on universal driving shaft connecting lever rotation path, and insulated tension pole lower link point self-locking qualifying bit while driving disconnecting link to be opened into limit position in limiting universal driving shaft, when the lower link point that this self-locking qualifying bit makes insulated tension pole departs from disconnecting link and opens in surmounting on insulated tension pole, lower link point and universal driving shaft are in a straight line together and do not surmount universal driving shaft axis place fore-and-aft plane.
In above-mentioned overall technical architecture, be the lower link point that makes insulated tension pole in surmount deviate from disconnecting link open in the straight line that is in together of the upper and lower pin joint of insulated tension pole and universal driving shaft, and be 3～5mm spacing with this straight line.
The technical scheme of the bright disclosed disconnecting link self-locking type outdoor AC three-phase linkage high-voltage isolating switch of the utility model, save the spring self-lock device always generally using, in disconnecting link opening process, between the special corner regions of insulated tension pole and connecting lever pin joint, utilize on insulated tension pole, the self-locking triangle position that lower link point and universal driving shaft form, coordinate again disconnecting link and insulated tension pole deadweight to form reliable self-locking state, the running of only could oppositely closing a floodgate under artificial actuating is intentionally moved, thereby avoid the misoperation technical problem of chopper switch, guarantee that it normally opens, for providing reliably, opens power circuit, close safety guarantee.
