Description
The utility model belongs to the switching device that the distribution of electricity is used, and is specifically related to the handle operation mechanism of circuit breaker on a kind of panel switches control cubicle.
Be used for the handle operation mechanism on the panel switches control cubicle circuit breaker at present, at least by handle, striking gear be connected handle and the jockey of striking gear three is partly formed, circuit breaker is fixed in the control cubicle, and striking gear is fixed on the circuit breaker, and handle is installed on the control cubicle door.When the circuit breaker of this switch control cubicle is worked, " combined floodgate ", " separating brake ", " tripping operation " and " button again " four operating states are arranged, and this one of four states indicates respectively at " ON ", " OFF ", " TRIP " and " RESET " with diverse location on the control cubicle door or on the handle of operating mechanism, guards the operating state of circuit breaker at any time in order to remind monitoring person.The technical scheme that has is the purpose that reaches dual monitoring, in certain operating state of the arrow points on the handle, is equipped with light or alarm signal is pointed out.As notification number be: the utility model patent of CN2047293U is exactly an example.The effect that obvious this scheme reaches is better, the technical scheme that adopts is but this scheme achieves the above object: the rotational angle with the relative control cubicle door of handle is controlled light or alarm signal, because of circuit breaker less from " combined floodgate " position transition to the angle of " tripping operation " change in location, the error that adds intermediate connector to transmit the angle variation and cause, so cause signal to transmit deficiencies such as inaccurate, that reliability is low, also cause error easily, even cause a serious accident.
The purpose of this utility model provides a kind of when being in " tripping operation " state at circuit breaker at least, has the light of accurate transmission signal and higher reliability or the operating mechanism of alarm signal indication.
For achieving the above object, the technical solution that the utility model adopts is: a kind of circuit breaker handle operation mechanism, by handle, striking gear, connect the jockey of handle and striking gear and have at least circuit breaker " tripping operation " working state signal indicating device four partly to form, described striking gear comprises shifting part and the strutting piece that the relative circuit breaker of shifting part is hinged location at least, described circuit breaker " tripping operation " working state signal indicating device is by switch, the series circuit that signal indicator elment and power supply are formed constitutes, one curved surface is arranged on the shifting part, switch is located at and this curved surface corresponding section, when shifting part rotates, curved surface on it and switch interact, and make series circuit be connection, disconnect two kinds of operating states.One cam is arranged on the described shifting part, and this cam is made of the positive camber of shifting part, and when circuit breaker during at " combined floodgate " state, shifting part cut-off switch, when circuit breaker went to " tripping operation " state, shifting part was connected switch.
Described switch can be that sensitive switch also can be other switch.Described signal indicator elment can be the alarm of signal lamp, alarm or the signal lamp of taking a message.Described shifting part can be a shift fork, also can be the form realization that connecting lever adds towing plate.
In the work, when causing circuit breaker from " combined floodgate " state-transition to " tripping operation " state owing to accident or other reason, curved surface on the shifting part and switch interact, and with switch connection, make the signal indicator elment in the series circuit send signal, to remind monitoring person.
Because above-mentioned solution will be come the control signal indicator elment to be improved to change with the angle of stirring the relative circuit breaker of element to realize with the gyration of the relative control cubicle door of handle in the prior art, made to the utlity model has following advantage:
＜1 〉. the transmission of " tripping operation " signal is accurate, has avoided changing the caused error of error that causes because of transmitting angle by many intermediate connectors.
＜2 〉. the reliability height, avoided because of intermediate connector damages the signal transmission failure that causes, thereby caused major accident to take place.
