Abstract

The invention discloses an SF6 gas leakage automatic detection method based on an infrared video. Video acquisition is carried on the location where SF6 leakage occurs, the alignment of different frame images is completed based on a feature point registration method, the sampled frame image is subjected to the image enhancement by an image enhancement method, the first frame image is taken as the comparison template, the image comparison of the different frame images is carried out by a multi-feature fusion comparison method, the difference between the adjacent frame images is found, the area having changed content between the frame images is recorded, and whether there is SF6 gas leakage in the monitoring point is determined according to the detection of the image change area. The method provided replaces the on-site detection method of the artificial carrying equipment, thereby reducing the working burden of electric inspection personnel and improving the safety.

Description

technical field [0001] The invention relates to a SF based on infrared video 6 Gas leakage automatic detection method. Background technique [0002] With the SF inside the substation 6 Increase in number of devices and increase in running time, SF 6 Gas leakage failure has always been an important issue that affects the normal operation of power equipment and threatens the personal safety of on-site workers. Thanks to SF 6 Due to the colorless and odorless physical characteristics of the gas, it is difficult to be directly discovered by the on-site staff, seeking a safe, timely and effective SF 6 Leak detection methods are particularly important. Past SF 6 Leak detection technologies are mostly passive detection methods, mainly including soap bubble brushing method, qualitative leak detector detection method, quantitative detection (bandaging method, hanging bottle method) and other methods. These methods have low sensitivity, are greatly affected by the surrounding en...
