Abstract: | The efficiency of SF6 leak detection is not satisfied currently. From the angles of detection accuracy, implementation methods, time-consuming of detection and detection results, this paper gives a brief review of the status of detection technology of electrical equipment SF6 leak, and a comparative analysis of the advantages and disadvantages of various detection techniques is made. Based on the analysis, the detection principle and the advantages and disadvantages of infrared imaging technology for SF6 leakage based on narrowband filter are described. With the application experience of the detection in recent years, the main points of infrared imaging detection and some detection methods are presented. Finally, the infrared imaging technology for SF6 leakage is illustrated with a case analysis. |
