Abstract

The invention relates to an intelligent SF6 density online monitoring data analysis and information feedback system. In the aspects of multi-dimensional data statistics and application, calculation and trend analysis of leakage rate, accurate compensation of environmental factors, comprehensive information feedback and processing suggestion pushing, a set of intelligent processing system is formedto automatically complete operations such as environmental data collection, defect reporting, fault prediction and alarming, and suggestions for maintenance methods, which will significantly increasethe rate of failure judgment and processing and avoid human misjudgment and reduction of operation efficiency.

Description

technical field [0001] The invention relates to an intelligent SF6 density online monitoring data analysis and information feedback system. Background technique [0002] The traditional SF6 density on-line monitoring system only samples the current data of the SF6 density meter, sends an alarm signal when the current value is lower than the alarm or lockout limit, or issues a lockout command through the protection device, and saves the historical data according to the set cycle, Calculate the leakage rate of the abnormal air chamber by manually observing the density change data or curve, and judge the corresponding defect standard and treatment measures. At the same time, the current temperature compensation measures for SF6 density are single, and there are situations such as over-compensation and under-compensation, which are not conducive to accurate analysis and comparison of SF6 density. [0003] Therefore, the present invention designs an intelligent SF6 density onlin...
