Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the 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 packaging 1 completely covers the flange 5, avoiding 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.
As an optional embodiment, one end of the air release plug 2 is provided with a thread, and one end of the air release plug 2 provided with the thread is connected with a screw cap 3; collecting SF6When in gas, the screw cap 3 is screwed on the air release plug 2; detection of SF6When gas is present, the screw cap 3 is unscrewed.
As an optional implementation manner, the packaging sleeve 1 is a flexible wear-resistant sleeve, and in this embodiment, high-strength plastics are selected, so that wear of iron parts during installation can be borne, and reuse is facilitated.
As an optional implementation mode, the bundling rope 4 is an elastic bundling rope, so that after bundling, pressure still exists on the packaging sleeve 1, and the sealing performance is improved; and the length of the bundling rope 4 can be adjusted, so that the bundling rope can be suitable for flanges 5 with different sizes.
As an optional embodiment, when the packaging sleeve 1 is installed, the air release plug 2 is positioned at the lower end, so that the operation of a detection person is facilitated.
