Cable gallery operation positioning protector of power distribution system

Abstract

The invention provides a cable gallery operation positioning protector of a power distribution system. The cable gallery operation positioning protector comprises a helmet and an oxygen production device connected with the helmet, wherein the helmet is provided with a helmet shell and a glass face mask; the glass face mask and the helmet shell are movably connected; the helmet shell is provided with a wireless communication device, a rechargeable battery, a positioning device, a lighting device, an oxygen content sensor used for sensing the oxygen content in a cable tunnel, a control device, a temperature controller, a detection assembly, a cooling fan, a carbon monoxide detection module, a wireless interphone, a facial recognition camera and an environment camera; the inner surface of the helmet shell is coated with an anti-radiation isolating layer, an LED ultraviolet lamp and a negative-ion generator are arranged in the helmet shell, and a concealed satellite receiving antenna is also arranged in the helmet shell. The cable gallery operation positioning protector is diversified in function and compact in structure, the personal safety of operating personnel is guaranteed, meanwhile, the cable gallery operation positioning protector also has the wireless communication function, so that people can conduct the operation at the construction site conveniently, and the work efficiency is improved; through the positioning device, the location of a wearer is rapidly locked.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a positioning protection device for cable corridor operation in a power 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 power load density in the central area of ​​the city is high, and the quality and reliability of power supply 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 centers use underground tunnels for power supply instead of high-altitude wires. However, because this method requires underground tunnels or cable interlayer operations, there is a tunnel environment problem that needs to be guaranteed to ensure the normal operation of the power supply system and the personal safety of workers entering the cabl...

AI Technical Summary

Problems solved by technology

However, because this method requires underground tunnels or cable interlayer operations, there is a tunnel environment problem that needs to be guaranteed to ensure the normal operation of the power supply system and the personal safety of workers entering the cable interlayer or tunnel maintenance. Cable tunnels and cable interlayer environments are 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
