Description
Summary:In order to measure the leakage of substation equipment's SF6 gas in the charged state, the current practice is the single infrared imaging in the power industry. But there are different factors such as wind speed, leak detection position, leak imaging can only be seen a flat area on the graph, not accurate positioning. The method in this paper is to joint spot and side, and first with infrared imaging legal out a flat area roughly, then gradually narrowed the leaking range by infrared absorption method, until the biggest SF6 gas density is detected, and it is just the leaking position. The method in the gas leakage detection of GIS substation charged is prevalent. The article has carried on the thorough analysis to the technology and successfully applied to the field of measurement.
