Abstract

The invention provides an SF6 equipment sealing flange gas leakage detection device and an application method thereof and belongs to the field of power equipment detection. The gas leakage detection device (100) comprises a flange covering part (101), a pipeline sealing part (102), a leakage detection port (103) and a main body unfolding port (104), wherein two ends of the flange covering part (101) are respectively connected with the pipeline sealing part (102), the main body unfolding opening (104) transversely penetrates through the flange covering part (101) and the pipeline sealing part (102) and is used for opening the flange covering part (101) and the pipeline sealing part (102) when the sealing flange (200) is mounted and dismounted by the gas leakage detection device (100), the leak detection port (103) is arranged on the flange covering part (101), and the leak detection port (103) is used for inserting an SF6 leak detector. The gas leakage detection device is advantaged inthat the objective of the invention is to solve problems of inconvenient operation and low precision in SF6 equipment sealing flange gas leakage detection.

Description

technical field [0001] The invention relates to the field of electric equipment detection, and more specifically relates to a gas leakage detection device and an application method of a sealing flange of SF6 equipment. Background technique [0002] The substation is an important part of the power system, and the substation is equipped with a large number of electrical equipment, among which SF6 equipment plays a vital role in the substation. At this stage, when carrying out gas leakage detection on the sealing flange of SF6 equipment, the local wrapping leak detection method is mainly used, that is, the leak detection is carried out by wrapping equipment with plastic film and sealing glue. Wrap the flange of the SF6 equipment completely with plastic film, and then seal the plastic film with sealing glue. After standing still for 12 hours, after the plastic film is perforated, an SF6 gas leak detector is inserted into the bottom of the sealed plastic film to detect leaks. A...
