Abstract
The invention claims a novel mistake-proof interlocking device of combined electrical apparatus used for preventing incorrect operations of combined electric switches, by adding a stopping rocker arm subassembly and a recessive isolation pair in the combined electrical apparatus composed of a vacuum circuit breaker and an isolation switch. In the stopping rocker arm subassembly, a pull pin is welded on a driving draw rod of the vacuum circuit breaker, a rocker arm shaft is mounted on the housing of the vacuum circuit breaker, a shifting fork matched with the pull pin and the stopping rocker arm are fixed on the rocker arm shaft. A stopping crank arm capable of contact locking with the stopping rocker arm and an interlocking crank arm jointed with the recessive isolation pair via an interlocking draw rod are respectively welded on a handle rotating shaft of open and close gate. The recessive isolation pair is jointed with an energy storage spring of the vacuum circuit breaker. The combined electrical apparatus composed of the high-pressure vacuum circuit breaker and the high-pressure isolation switch of the invention is provided with simple structure, convenient operation and low cost, capable of effectively preventing from accident of man-made incorrect operation and improving safety and reliability thereof.
Description
Technical field
The present invention relates to the electric switch technical field, especially include the no arc extinguishing of two or more switch room interlockings or the high-pressure air circuit breaker of flash guard.
Background technology
The anti-mistaken interlocking device of the combined electrical apparatus of the outdoor high-voltage vacuum breaker+outdoor high-voltage isolating switch of present domestic use, all be unidirectional, promptly can guarantee under the breaker closing state that isolating switch can not separating brake, only under the breaker open operation state, could disconnecting switch operation; And under the state of isolating switch separating brake, circuit breaker but can close a floodgate, if this misoperation also can work the mischief to safety.
Summary of the invention
The objective of the invention is to improve at the above-mentioned structure that may produce misoperation; a kind of anti-mistaken interlocking device of combined electrical apparatus of novelty is provided; make the combined electrical apparatus of outdoor high-voltage vacuum breaker+outdoor high-voltage isolating switch have two-way anti-error interlock protection; promptly isolating switch can not be realized separating brake under the breaker closing state; and under the state of isolating switch separating brake, circuit breaker can not be realized closing a floodgate, and not only makes safe and reliable to operation; and simple in structure, cost is low, and is easy to operate.
For achieving the above object, technical scheme of the present invention is like this: a kind of anti-mistaken interlocking device of combined electrical apparatus of novelty, be in the combined electrical apparatus that constitutes by outdoor high-voltage vacuum breaker and outdoor high-voltage isolating switch, set up stop rocker arm assembly and the recessive pair of isolating; Said stop rocker arm assembly is to be welded with finger on the drive stay of vacuum circuit-breaker, is fixed with rocker shaft bed on the housing that vacuum opens circuit, and rocker arm shaft is installed on the rocker shaft bed, is welded with shift fork on rocker arm shaft, and this shift fork matches with said finger; Also be connected with the stop rocking arm in the rocker arm shaft outer end, and be furnished with stop and regulate bolt; Be welded with stop connecting lever and interlocking connecting lever on the divide-shut brake arm pivot post of isolating switch respectively, wherein stop connecting lever and said stop rocking arm can be decided by contact plug; On said interlocking connecting lever, be hinged with the interlocking pull bar; Said recessive isolate secondary by with the interlocking pull bar can relative slippage the slip connecting lever, interlocking rotating shaft with the welding of slip connecting lever, and the ratchet that is connected on the interlocking spring assembly in the interlocking rotating shaft and connects by the interlocking spring assembly, the torsion spring that connects with ratchet, the ratchet that matches with ratchet is formed, and the energy-stored spring of ratchet and vacuum circuit-breaker links.
Its course of action is such: when the vacuum breaker closing, because the motion of drive stay, finger on the drive stay is stirred shift fork and is rotated, drive is rotated with the integrally welded rocker arm shaft of shift fork, the stop rocking arm that is connected with rocker arm shaft turns to closing position thereupon, and with the stop connecting lever self-locking that is welded on the isolating switch divide-shut brake arm pivot post, thereby guaranteed that under the situation of breaker closing isolating switch can not separating brake;
Behind breaker open operation, when carrying out the isolating switch separating brake, being fixed on rotating shaft on the isolation knife divide-shut brake handle drives the interlocking connecting lever be welded as a whole and rotates together, pulling interlocking pull bar moves upward, and by slip connecting lever drive interlocking rotating shaft rotation, thereby the spring that connects ratchet is elongated, when the isolating switch separating brake puts in place, spring also is elongated and puts in place, but this moment ratchet the torsion of torsion spring and with the frictional force double action of ratchet under, do not break away from ratchet, still be in normal contact condition, but formed and recessive isolated secondaryly, this moment is if carry out the misoperation of breaker switching-on operation, because at the pulling handle and rotating ratchet moment, eliminated the frictional force between ratchet and ratchet, the recessive pair of isolating is had an effect, and the spring tension that be stretched this moment discharges suddenly, makes ratchet hightail ratchet, make ratchet form idle running, and can not make the energy-stored spring energy storage, also just can not finish the closing operation of circuit breaker naturally, and then prevent the generation of misoperation accident.
Owing to taked technique scheme; the anti-mistaken interlocking device of combined electrical apparatus of a kind of novelty of the present invention; to increase recessive mode of isolating secondary and stop rocker arm assembly; realized between high-pressure vacuum breaker+high voltage isolator not only connecting each other but also mutual restriction; make it to have two-way anti-error defencive function; not only simple in structure, easy to operate, cost is low, and can effectively avoid the generation of artificial misoperation fault, has improved the security reliability of operation.
