The invention belongs to the technical field of automatic control and particularly relates to a voice prompt device for preventing a high-voltage switch cabinet from being locked due to misoperation.The voice prompt device provided by the invention comprises a voice module, and the type of the voice module is YT07. The voice prompt device can effectively prevent the occurrence of the switching-onaccident of a vacuum circuit breaker of the high-voltage switch cabinet due to misoperation. Before the vacuum circuit breaker is switched on, safety process confirmation is performed through voice prompt, and after confirmation, the switching-on operation of the vacuum circuit breaker can be performed; otherwise, the high-voltage switch cabinet is locked, and the switched-on circuit is disconnected so as to achieve the effect of preventing misoperation on the high-voltage switch cabinet. The voice prompt device provided by the invention saves time and labor, can realize accurate check, can find the misoperation phenomenon of the high-voltage switch cabinet in time, and has high reliability. A voltage stabilizing module with the type of 7812 is adopted, and a chip is small in volume, lowin cost and high in reliability.
Description
technical field [0001] The invention belongs to the technical field of automatic control, in particular to a high-voltage switch cabinet anti-misoperation locking voice prompter. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The main function of the switchgear is to open, close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. Once the high-voltage switchgear is misoperated, it is prone to closing accidents. [0003] In the prior art, it is usually manually checked whether there is any misoperation of the high-voltage switchgear, which is not only time-consuming and laborious, but also inaccurate, and the misoperation of the high-voltage switchgear cannot be found in...
