Research on insulated gas leakage detection and emergency disposal technology in confined space

In order to meet the needs of insulated gas leakage monitoring and emergency environmental protection disposal in power confined space, the infrared remote sensing and efficient separation environmental protection disposal technology of insulated gas are studied, and the linkage scheme of insulated gas leakage monitoring and emergency disposal is constructed. A new infrared telemetry method for insulated gas leakage monitoring in confined spaces based on multivariate optical technology was proposed to achieve high-precision and large-scale imaging monitoring of insulated gas. A high-efficiency separation method for insulating gas based on membrane adsorption was proposed to address the issues of large volume and low concentration mixed gas recovery and environmental protection disposal in confined spaces, achieving emergency recovery and disposal of insulated gas. We have constructed an integrated linkage technology for monitoring and emergency response of insulated gas leakage in confined spaces, and proposed a gas monitoring and emergency response plan for typical indoor substations. The feasibility of the proposed method had been preliminarily verified through application demonstration, providing a technical and methodological reference for monitoring and handling insulation gas leakage in confined spaces.
