Personal safety protection device for distribution network

Abstract

An embodiment of the invention discloses a personal safety protection device for a distribution network. The personal safety protection device comprises a body, an LED display screen and an LED alarming lamp which are arranged on a main panel of the body, a loudspeaker arranged at the bottom part of the body, and a digital map memory, an induction processing circuit and an alarm circuit which arearranged inside the body, wherein a real-time position of an operator is monitored by means of the digital map memory and a human body infrared sensor chip, the electric field intensity of the currentposition of the operator is obtained by means of an electric field acquisition chip and an electric field comparator, whether the electric field intensity is greater than or equal to a preset electric field intensity threshold is judged, if a judgment result is positive, the situation indicates that the current position of the operator is in a dangerous charged region, and an alarm is issued by means of an alarm circuit to remind the operator to stay away from the dangerous region. The personal safety protection device for the distribution network disclosed in the invention can issue an alarmwhen the operator mistakenly enters the charged region, thereby effectively guaranteeing the safety of the operator.

Description

technical field [0001] The present application relates to the technical field of electric power safety protection, in particular to a personal safety protection device for distribution network. Background technique [0002] When overhauling or troubleshooting the equipment in the power system, the operating equipment adjacent to the equipment that needs to be overhauled is usually in a charged state. This type of live operating equipment is called a "dangerous point" in the safety production work of the power system. In order to prevent maintenance operators from entering the area where live equipment is located by mistake, boarding or touching live equipment by mistake, resulting in personal and equipment accidents, it is necessary to shield the barriers or fences between the operating equipment adjacent to the maintenance site, as well as the aisle where passage is prohibited. Hang a "stop, high voltage danger" sign on the fence or fence to warn maintenance workers not to ...

AI Technical Summary

Problems solved by technology

However, in the actual work process, due to factors such as lack of concentration, work fatigue, and carelessness of the maintenance workers, it is easy for the maintenance workers to enter the live area and touch the live equipment by mistake.

At present, operators usually rely on human eyes to determine the safe distance. As the operating environment of the power system becomes increasingly complex, the safety of operators cannot be effectively guaranteed
