Abstract

The invention discloses an on-off state display, comprising a microprocessor module, a high-voltage charged indicating circuit and an input quantity circuit and further comprising a state display circuit, a voice prompting circuit, a light source sensing circuit and an emergency illumination circuit, which are respectively connected with the microprocessor module. In the on-off state display disclosed by the invention, the voice prompting and emergency illumination functions are added, so that the efficiency and safety in monitoring and repairing of a switch cabinet can be improved; and a plurality of module manners communicated with a background monitoring terminal are provided and the application range of the on-off state display is widened, so that the on-off state display has good prospect of application.

Description

technical field [0001] The invention relates to a switch state display and belongs to the technical field of electric power system control. Background technique [0002] With the continuous and rapid development of the power system, the user's functional requirements for the switch state display on the switch cabinet of the medium voltage system of the circuit are also gradually increasing. Although the existing switch state display has a good switch state indication function and integrates For example, the primary circuit simulation diagram, circuit breaker position, high-voltage live indication and other functions are integrated into one, which is convenient to use. However, the general switchgear room is a closed room with low light, and an external lighting power supply needs to be added. In the process of switching cabinets, the external lighting power supply is suddenly cut off, and the current switch-shaped display has many integrated functions without voice prompts. ...
