Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the GIS gas leakage detection bag is used for gas leakage detection of a flange 5, and comprises a packaging sleeve 1 and a bundling rope 4 connected to two ends of the packaging sleeve 1, wherein the bundling rope 4 is used for sealing two ends of the packaging sleeve 1; the packaging sleeve 1 is coated outside the flange 5 and used for collecting SF possibly leaked from the flange 56A gas; the upper end of the packaging sleeve 1 is provided with two sealing zippers 6, so that the packaging sleeve is convenient to install at any time and any place and is not required to be installed when GIS equipment is installed; the two sealing zippers 6 are connected to realize the sealing of the rest two ends of the packaging sleeve 1; the lower end of the packaging sleeve 1 is provided with an air release plug 2, so that the packaging sleeve 1 is prevented from being punctured and SF (sulfur hexafluoride) is conveniently released6A gas.
As an alternative embodiment, the packageThe sleeve 1 completely covers the flange 5 to avoid SF6Gas leaks from the uncoated area of the flange 5, which results in no collection of SF in the package 16A gas.
As an alternative embodiment, the packaging sleeve 1 is square after being unfolded, so that the packaging sleeve 1 with the size corresponding to the flange 5 can be selected conveniently.
As an alternative embodiment, the side length of the edge of the packaging sleeve 1 without the sealing zipper 6 is larger than the outer circumference of the flange 5, so that the packaging sleeve 1 can be mounted on the flange 5.
