GIS equipment state on-line monitoring system

Abstract

The invention provides a GIS equipment state on-line monitoring system. The system comprises a monitoring host and a plurality of bus pipelines with preset lengths; each bus pipeline is provided with at least one expansion joint, a temperature sensor and a humidity sensor; each telescopic joint is provided with a displacement sensor; and the monitoring host judges whether the expansion joint state data is within a preset threshold range or not according to the received data. According to the method, the corresponding parameter data can be rapidly extracted based on the needs of the user. From the obtained expansion joint data, identification code configuration is performed on target expansion joint data of each expansion joint to obtain a state data identification code of each expansion joint, and according to the state data identification code of each expansion joint, an association network is constructed so as to associate different expansion joints and perform analysis and pre-judgment on a fault; and a user can monitor and uniformly manage most expansion joints in the system. Single management one by one is avoided, the monitoring efficiency is improved, the monitoring effect is ensured, and the failure rate in the system is reduced.

Description

technical field [0001] The invention relates to the technical field of telescopic joint monitoring, in particular to an online monitoring system for GIS equipment status. Background technique [0002] At present, GIS equipment is mainly composed of switches, current transformers, isolating switches, pipeline busbars, threading bushings, expansion joints and other equipment. Among them, the bus duct is an important part of GIS, and its length is generally several hundred meters. The GIS equipment expansion joint is used as an auxiliary equipment of the pipeline busbar. Its basic function is to adjust the length adjustment compensation of the GIS equipment during installation and to compensate the expansion and contraction changes of the pipeline busbar barrel with the season and environmental temperature changes after operation. The length of the busbar of the GIS pipeline will change with the change of the ambient temperature. If the GIS expansion joint cannot play the role...

Problems solved by technology

[0005] However, in order to fully understand the system status, many parameters will be monitored, and the data will be uploaded and compared in real time, which cannot reflect the outstanding monitoring of the data that users care about.

Moreover, the operation of multiple GIS devices on site results in a large amount of data being uploaded to the host computer. The identification and analysis of the data consumes a lot of resources of the host computer, which affects the processing efficiency, and only one type of data of the GIS device can be compared. Monitoring, the timeliness of lagging monitoring is easy to cause the failure of multiple GIS equipment
