Description
Technical field
The utility model relates to a kind of appliance switch, and it relates to a kind of plyability on-load switch combined electrical apparatus that has emergency tripping device in particular.
Background technology
At present, the arc-extinguishing medium in the on-load switch combined electrical apparatus of prior art mainly contains four types of air-generating, air pressing type, vacuum type and sulphur hexafluoride formulas, and that utilizes the air dielectric arc extinguishing mainly contains two kinds of air-generating, air pressing types.The plyability on-load switch combined electrical apparatus of air-generating because simple in structure, operating work is little, easy to maintenance, cheap and with a long history, technology maturation, present many advanced technology country is still adopted in a large number.Air-generating on-load switch combined electrical apparatus mainly utilizes electric arc to burn gas exhausted material, makes it to decomposite a large amount of gases.Form air-blowing and come extinguish arcs, stronger than the high-current on-off ability than air pressing type, but not enough be that little electric current cut-offs because gas production is little, arc quenching effect is not as air pressing type, electric arc is relatively big to the arc control device scaling loss, has reduced the useful life of arc control device.
The principle that the pressure-operated load switch combined electrical apparatus adopts is a compressed air, the high pressure draught that forms by spout brushes electric arc to be made it to extinguish, little electric current cut-offs and is better than air-generating, but owing to be subjected to the piston stroke or the diameter of the restriction air pressing type of operating work can not be too big, it is critical that the spout air velocity can not reach, and particularly certain qualification arranged during transfer current so it extinguishes heavy current, cut-offs not as air-generating than heavy current, operating function demand height has restricted the raising of drop-out current.In addition, when prior art on-load switch combined electrical apparatus there not being electric branch function, perhaps under the situation that manual station breaks down and operating grip is lost, can't realize separating brake, the big iron hook of usefulness that can only be artificial goes hook to start the contact separating brake.
Summary of the invention
The purpose of this utility model be overcome weak point of the prior art provide a kind of collect aerogenesis, piston gas-pressing help blow, magnetic blow-out is cooled to one can cut-off bigger electric current, can cut-off little electric current again, the plyability on-load switch combined electrical apparatus of emergency tripping device is taken into account and had to big or small electric current.The technical scheme that solves the problems of the technologies described above is: a kind of plyability on-load switch combined electrical apparatus that has emergency tripping device, and this plyability on-load switch combined electrical apparatus that has emergency tripping device mainly comprises: underframe, transmission mechanism, tripping mechanism, spring energy agency, operating mechanism, arc control device; Described underframe is made up of crossbeam and frame, and supporting insulator, fixed contact, moving contact, the first side installation of movable contact moving arcing contact are installed on crossbeam; Described transmission mechanism is made up of main shaft, dropout universal driving shaft, moving arcing contact extension spring; Described tripping mechanism mainly comprises locking board, rocking arm; Described spring energy agency is made up of combined floodgate spring, sluice separating spring, also include emergency tripping device, described emergency tripping device by dropout arm-tie, steel lock, pull bar, draw to turn round and form, described drawing turned round cylinder lever connecting rod one end, the pull bar other end connects steel and locks an end, the steel lock other end connects dropout arm-tie one end, and the dropout arm-tie other end connects tripping mechanism.
The beneficial effects of the utility model are: the utility model is widely used in electric power system, oil field, mine and urban network restructuring, the upgrading of rural power grids etc., and it compared with prior art has following good effect:
1. simple in structure, operating work is little, cheap, advanced technology.
2. improved the ability of drop-out current ability and transfer current, can cut-off bigger electric current and can cut-off little electric current again, accomplished that big or small electric current takes into account.
3. piston of the present utility model adopts the high yield gas material to make, piston can not only the aerogenesis arc extinguishing, the air-flow that utilizes simultaneously quick rotation to produce again carries out arc extinguishing, realize the plyability arc extinguishing, arc extinguishing speed is faster, reduced the damage of electric arc, increased the useful life of arc control device, thereby saved manpower, material resources and financial resources arc control device.
4. the utlity model has emergency tripping device, having solved prior art is not having electric branch function, perhaps can't realize the defective of separating brake under the situation that manual station breaks down and operating grip is lost.As long as pulling out emergency tripping device insures a utmost point and spurs second utmost point again, switch is with quick acting switching-off, in case of emergency saved the quality time, simultaneously can also hang up the stay cord remote operation drawing to turn round, so just guaranteed operating personnel's disjunction under the super large load condition more, the switch blast that causes because of arc short-circuit damages the person, guarantees personal safety.
