Passive ultrahigh-voltage power grid cable and bus connecting piece temperature continuous monitoring and recording system

Abstract

The invention discloses a passive ultrahigh-voltage power grid cable and bus connecting piece temperature continuous monitoring and recording system, which comprises a data processing and recording server, a wireless receiving module, a plurality of temperature collectors and a monitoring terminal. Each temperature collector comprises an induction circuit, a temperature collection sensor and a wireless transmitting module; wherein each ZigBee slave module is in wireless connection with a ZigBee main module through a ZigBee protocol to transmit data, the ZigBee main module is in wireless connection with the data processing and recording server through a GPRS network, and the monitoring terminal is connected with the data processing and recording server through the Internet. Continuous monitoring can be realized; battery power supply is not needed, and the problem of battery replacement of ultrahigh-voltage equipment is solved; a 5G network technology is adopted, data response is fast, and no time delay exists; data can be accessed through a PC terminal and an intelligent terminal; the ZigBee wireless module is large in detection point capacity; the construction and installation time is short; and modular combination can be realized.

Description

technical field [0001] The invention relates to the technical field of 5G Internet of Things communication, in particular to a continuous temperature monitoring and recording system for passive ultra-high voltage power grid cables and busbar connectors. Background technique [0002] With the modernization and development of society, people are increasingly inseparable from electricity, and electricity is composed of power plant generation, step-up station step-up, power grid transmission, step-down, power distribution and other links. High-voltage power cables and busbars are important components of high-voltage power grids. Poor contact of high-voltage cable connectors will cause large-scale power outages to the high-voltage power transmission system, which will bring great harm to national security and social order and stability. High-voltage power cables and busbars are composed of multiple cables or multi-segment power busbars. There are many joints between cables and ca...

AI Technical Summary

Problems solved by technology

The traditional methods for measuring the temperature of cables and busbars are: sticking color-changing temperature test wax stickers on joints or connectors, infrared temperature measurement guns, infrared thermal imagers and other measurement methods. Traditional measurement methods have the disadvantages of continuous monitoring, Can not record, can not track the problem of the first fault
