Abstract

The invention provides a monitoring and protection system for operations of a power supply and distribution system in a low oxygen environment. The monitoring and protection system comprises helmets provided for the personnel to wear on the operating site and a cloud server which is in communication connection with each helmet, and is characterized in that the cloud server and each helmet take an SDH (Synchronous Digital Hierarchy) loop network as a communication medium, and the cloud server realizes synchronous sampling for data of each helmet by adopting an IEEE 1588 synchronization method; switches supporting an IEEE 1588 communication protocol are uniformly arranged in a low oxygen environment area so as to realize network connection between each helmet and the cloud server and network connection between the helmets; each helmet is provided with a helmet shell and a glass mask; the glass mark is movably connected with the helmet shell; and data information of each helmet is uploaded to the cloud server in real time, so that the cloud server is enabled to master operation information in the low oxygen environment in real time, and the monitoring personnel is enabled to command timely and accurately.

Description

technical field [0001] The invention relates to the field of electric power safety, in particular to a monitoring and protection system for a power supply and distribution system operating in a hypoxic environment. 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 work...
