Problems solved by technology

[0002] At present, the only GIS online partial discharge monitoring and diagnosis system with single function, or SF6 gas micro-water density monitoring system
However, conditions such as GIS partial discharge and SF6 gas micro-water density usually appear in power industry equipment at the same time and have a destructive impact on it
In the past, the GIS online partial discharge monitoring system and the SF6 gas online monitoring system were installed in the installation room of the power equipment. These two systems are bulky and costly, and there are some modules in the two systems, such as power supply and data processing. modules are repeated

Abstract

The invention provides a GIS (Geographic Information System) online monitoring system, which mainly comprises a UHF (Ultra High Frequency) high-frequency partial discharge sensor, an SF6 sensor monitor, a data acquisition device and a data processing server. A GIS partial discharge measuring module comprises a UHF sensor and a background analyzing system; the SF6 sensor monitor comprises an SF6 micro-water density monitoring sensor and an SF6 environment monitoring sensor; and the data acquisition device comprises a power supply unit, an SF6 micro-water monitoring unit, an SF6 environment monitoring unit and a partial discharge monitoring unit. The functions of the monitoring and diagnosis of GIS partial discharge, the environment monitoring of an SF6 switch chamber, and the online monitoring of the micro-water density of SF6 gas are integrated; the partial discharge of the inner part of insulating equipment as well as the temperature, the humidity and the density of the SF6 gas can be monitored on line; the GIS online monitoring system has the advantages of compact structure, low cost and high accuracy; and the real-time display of data can be realized.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a GIS online monitoring system. Background technique [0002] At present, there are only GIS online partial discharge monitoring and diagnosis system with single function, or SF6 gas micro-water density monitoring system. However, conditions such as GIS partial discharge and SF6 gas micro-water density usually appear in power industry equipment at the same time and have a destructive impact on it. In the past, the GIS online partial discharge monitoring system and the SF6 gas online monitoring system were installed in the installation room of the power equipment. These two systems are bulky and costly, and there are some modules in the two systems, such as power supply and data processing. Modules are repetitive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a GIS online monitoring system, which integrates the functions of G...
