Power supply and distribution system electric cable interlayer operation monitoring protective device

Abstract

The invention provides a power supply and distribution system electric cable interlayer operation monitoring protective device. A helmet is provided with an outer shell and an internal net in contact with a human head; a wireless communication device, an electricity storage device and a positioning device are mounted; people is enabled to conveniently instruct operation at a construction filed, working efficiency can be improved, impact force can be effectively reduced via a buffer ring, safet of a safety helmet can be increased, a heat dissipation fan and a temperature control device can be used for temperature reduction according to a set temperature, and therefore heat dissipation effects can be exerted. The wireless communication device, the positioning device, an illuminating device, an oxygen content sensor, a control device, the heat dissipation fan, a detection assembly, a carbon monoxide detection module, a facial recognition camera and an environment camera are respectively connected with the electricity storage device, the electricity storage device is used for supplying electric power, an electricity quantity of the electricity storage device can be detected via a processor, and the protective device can be prevented from malfunctioning due to a low electricity quantity of the electricity storage device when crisis time comes.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a monitoring and protection device for cable interlayer operation in a power supply and distribution system. Background technique [0002] The central area of ​​the city is densely populated, and the administration, economy, commerce, and transportation are relatively concentrated. The density of electricity load in the central area of ​​the city is high, and the requirements for power supply quality and reliability are high, which puts forward higher requirements for power supply network and power supply facilities. With the progress of modern cities, more and more urban central areas use underground tunnels or cable interlayer power supply instead of overhead wires. However, this method requires underground tunnels or cable interlayer operations, so there is a tunnel. The problem of the cable interlayer environment needs to be guaranteed to ensure the normal operation of t...

AI Technical Summary

Problems solved by technology

However, because this method requires underground tunnels or cable interlayer operations, there is a tunnel. The problem of the cable interlayer environment needs to be guaranteed in order to ensure the normal operation of the power supply system and the personal safety of the staff entering the cable interlayer or tunnel maintenance. Cable tunnels, cables The interlayer environment is complex. In the cable tunnel and the air in the cable interlayer, the oxygen content is low, and there are many harmful gases such as carbon monoxide, methane, hydrogen sulfide, etc., which bring great safety hazards to maintenance personnel.
