Description
Technical field
The present invention relates to the high-tension switch cabinet technical field, be specifically related to a kind of five-prevention operation mechanism of high-tension switch cabinet.
Background technology
The action need of the isolating switch of high-tension switch cabinet, earthed switch, circuit breaker, cabinet door satisfies " five is anti-" interlock requirement, prevents that on-load from dividing, closing isolating switch that is:; Prevent from dividing by mistake, closing circuit breaker; Prevent from being with ground wire to close isolating switch; Prevent live connection of ground wire; Prevent mistakenly entering charged chamber.
At present, the mechanical interlock mechanism of all kinds of high-tension switch cabinets is varied, the operation board of four transverse arrangement of turbo of some employings, operation board connects upper and lower isolating switch and upper and lower earthed switch by connecting rod, handle hole is directly arranged on the operation board, handle hole is not provided with radical occlusion device, and itself and circuit breaker are interlocked complicated; This operating mechanism causes the switch cubicle lateral dimension large, floor space is large and high especially to operation requirements, need to lean on skilled operation personnel thinking sequentially to realize and come the console switch cabinet, because of handle hole without covering device, the easy wrong dislocation operation of operating personnel, namely damaged operating mechanism, and the switch of its connection is opened in the mistake damage, causes contingency.
Some operating mechanisms adopt four operating axis of passive type positive lock to realize upper and lower isolating switch in the switch cubicle, upper and lower earthed switch, circuit breaker, have four handle holes before the switch cubicle, operating grip can insert but can't rotate, and easily damages operating mechanism during this passive type interlocking device operation; Also there is handle hole to stop and adopts the multichip connection form, connect fulcrum many, parts are many, high with the switch cubicle installation difficulty, successively operating sequence must be observed strict regulation, and these mechanical interlock mechanisms are all very complicated, poor reliability, this complicated machinery interlock complex operation, and possible misoperation, thus immeasurable loss caused.
Solve the defective of existing operating mechanism for high voltage switch cabinet, it is CN201120105055.0 " a kind of operating mechanism for high voltage switch cabinet " that the inventor has designed China Patent No. for this reason, and it adopts single control end, has solved the deficiency that traditional a plurality of control end exists; But isolating switch, earthed switch, circuit breaker in the applied high-tension switch cabinet of this operating mechanism for high voltage switch cabinet, can only in cabinet, adopt forward to install, transmission device (transmission device is gear train) need be set between the Geneva mechanism of operating side and driving isolation switch, earthed switch in its operating mechanism, the transmission direction that changes transmission device just can realize not in the control end of rotation direction intersection and the transmission between the Geneva mechanism, the setting of transmission device causes whole operating mechanism complex structure, drive path is long, causes operating the relatively poor defective of reliable transmission; For making each electric device characteristics of compact layout in the high-tension switch cabinet, high-tension switch cabinet body is narrowed down and operate reliable, the interior isolating switch of high-tension switch cabinet, earthed switch, circuit breaker adopt the side dress to arrange, above-mentioned like this operating mechanism for high voltage switch cabinet can't realize that high-tension switch cabinet is to the side dress layout of isolating switch, earthed switch and circuit breaker.
