Safety protection system for high and low-voltage electrified bodies

Abstract

The system discloses a safety protection system for high and low-voltage electrified bodies. The system comprises a high-voltage electrified body, a low-voltage electrified body, a high-voltage switch tripping loop, a proximity monitoring subsystem, a voltage detection subsystem and an electrification warning subsystem; the proximity monitoring subsystem monitors approaching targets through a microwave probe and transmits monitoring signals to an AND logic module, wherein the AND logic module is connected with the high-voltage switch tripping loop; the voltage detection subsystem detects the voltage of the high-voltage electrified body and the low-voltage electrified body through a measurement unit and transmits high-voltage signals and low-voltage signals to a high-voltage signal acquisition processing module and a low-voltage signal acquisition processing module, wherein the high-voltage signals are transmitted to the AND logic module and act together with the monitoring signals so as to control a high-voltage switch to trip; and the electrification warning subsystem includes a high-voltage warning light, a low-voltage warning light and electric quantity display screens and is connected with the high-voltage signal acquisition processing module and the low-voltage signal acquisition processing module so as to perform electrification warning and display. With the system adopted, an operator who wrongly approaches electrified bodies or wrongly dissembles electrified wires can be warned, and therefore, injuries caused by electric shock accidents can be avoided, and personal safety can be ensured.

Description

technical field [0001] The invention relates to a safety protection system for a high and low voltage electrified body. Background technique [0002] Electric shock accidents account for a large proportion of all kinds of accidents in related industrial and mining enterprises. The main factors of electric shock accidents are the wrong switch position, approaching or contacting live high-voltage bodies, misidentifying equipment or mistakenly dismantling low-voltage live terminals. [0003] The protection of electrical equipment has developed from electromagnetic type and integrated circuit type to microcomputer type protection and photoelectric type protection that has not yet become the mainstream. The development of various forms of protection technology is changing with each passing day. The more convenient, the more powerful the functions, but it has been stagnant in terms of the safety protection of the users of electrical equipment. For electric shock accidents, the hig...

Problems solved by technology

[0004] The reason for this situation is that the protection of high and low voltage charged bodies is still at the level of passive protection, which depends on the completeness of the safety system and the subjective initiative of employees.
