GIS busbar cabin mechanical strength monitoring system based on ubiquitous electric power Internet of Things

Abstract

The invention relates to a GIS busbar cabin mechanical strength monitoring system based on the ubiquitous electric power Internet of Things, wherein ranging sensors are provided on any one or two of two opposite end faces of two ends of a ripple compensator, an infrared imaging sensor is provided on any one of the ends, a vibration sensor is provided on any of the ends, and the output ends of theranging sensors, the infrared imaging sensor and the vibration sensor are connected to a handheld device and / or a computer. Based on multi-sensors, data transmission and data processing, the inventioncan monitor the temperature distribution, stress deformation and vibration of the GIS busbar cabin enclosure and expansion joints in real time, and record a large amount of data, which makes comprehensive evaluation of the mechanical performance of the busbar cabin while ensuring the safe and stable operation of the GIS busbar cabin, performs early warning on excessive stress failure in the busbar cabin, and provides data support for analyzing the impact of temperature distribution on the mechanical performance of the GIS busbar cabin.

Description

technical field [0001] The invention belongs to the technical field of GIS busbar compartment mechanical strength monitoring, in particular to a GIS busbar compartment mechanical strength monitoring system based on the ubiquitous power Internet of Things. Background technique [0002] Gas Insulation Station (GIS for short) is a combination of electrical equipment such as circuit breakers, isolating switches, voltage transformers, current transformers, lightning arresters, and busbars, all of which are packaged in metal casings. Grounding is required, and the shell is filled with SF6 gas or SF6 / N2 mixed gas with a pressure of 0.3-0.6MPa as the phase-to-phase and ground-to-ground insulation medium. GIS has the advantages of small footprint, all components are sealed from environmental interference, small maintenance workload, long maintenance cycle, flexible configuration, no electromagnetic interference, convenient operation, high reliability, convenient and simple installati...

AI Technical Summary

Problems solved by technology

When the ambient temperature changes rapidly, the corrugated compensator is frequently subjected to changes of sometimes stretching, sometimes shrinking, and sometimes twisting, which is likely to cause fatigue, so that the expansion joints installed on the busbar cabin cannot fully compensate for the changes in thermal expansion and cold contraction, resulting in the weld seams of the cabin Cracking, gas leakage, ground discharge breakdown, pull-out or topping of the bus connection, etc., will eventually cause equipment damage or even personal injury

The bus failure will directly affect the power supply of the grid, resulting in large-scale power cuts and blackouts

At present, there is no standard solution for online monitoring and early warning of excessive stress in the busbar cabin in my country, and there is no clear quantitative standard for the cause of the displacement and deformation of the busbar cabin; to prevent
