Description
Technical field
The utility model belongs to the low pressure equipment for power transmission and distribution, relates to the operating mechanism parts of low-voltage circuit breaker, specifically is a kind of breaker closing indicating mechanism that is used for the breaker spring operating mechanism.
Background technology
The existing circuit breaker spring operation generally all have can be on guidance panel the state indication mechanism of display working condition, common state indication mechanism comprises that whether to be used for prompting operation person's circuit breaker is in the divide-shut brake indicating mechanism of separating brake or "on" position and is used for prompting operation person's spring energy agency ready energy storage state indicating mechanism of energy storage.The implementation of this function generally is divide-shut brake indication piece and the energy storage indication piece that lever construction is set, by swinging between different indicating positions with the parts drive divide-shut brake indication piece and the energy storage indication piece of close/open machine and stored energy mechanism interlock, the sign board of indication piece front end just can have the different operating state of demonstration on the panel of display window.When carrying out the closing operation of circuit breaker, must satisfy circuit breaker and be in gate-dividing state and the stored energy mechanism condition of energy storage, though the operator can judge whether the preparation of closing a floodgate is ready by the prompting of above-mentioned existing each indicating mechanism, but owing to the ready state that closes a floodgate is not directly pointed out, make troubles therefore still for operator's operation, misoperation also takes place easily.
Summary of the invention
Technical problem to be solved in the utility model is, improves on the architecture basics of standing state indicating mechanism, and a kind of indication mechanism for preparation of breaker switchingin that can indicate the ready state of breaker closing clearly is provided.
Indication mechanism for preparation of breaker switchingin of the present utility model includes the divide-shut brake indication piece and the energy storage indication piece of lever construction, the fulcrum of the equal cross-under in middle part of divide-shut brake indication piece and energy storage indication piece conduct swing in same rotating shaft; Also be provided with the preparation indication piece that closes a floodgate on this basis, the middle part of this preparation indication piece that closes a floodgate also cross-under also can rotating shaft be a spot wobble in above-mentioned rotating shaft, combined floodgate is prepared the cross-under position of indication piece between divide-shut brake indication piece and energy storage indication piece, and the front end of preparing indication piece that closes a floodgate is provided with sign board; Back segment that close a floodgate to prepare indication piece is connected with a pin with shaft parallel, back segment at divide-shut brake indication piece and energy storage indication piece is respectively arranged with first blocking surface and second blocking surface simultaneously, and described pin extends to the top of first blocking surface and second blocking surface to both sides.Between combined floodgate preparation indication piece and rotating shaft, also be provided with and make the spring of preparation indication piece back segment that close a floodgate to lower swing.
The place ahead in rotating shaft, also be provided with a limit shaft with shaft parallel, simultaneously at the divide-shut brake indication piece, to have with the rotating shaft center on the matrix of the leading portion of preparing indication piece and energy storage indication piece of closing a floodgate be the stopper slot of the arc in the center of circle, described limit shaft has run through the stopper slot on three indication pieces.
The utility model is simple in structure, its implementation is directly to increase indication piece arranged side by side in the rotating shaft of traditional state indicating mechanism, thereby be easy to realize, utilize cooperating of blocking surface on pin and the existing indication piece simultaneously, can realize the accurately ready purpose of prompting combined floodgate, make things convenient for the operator, avoided misoperation.
