Description
Technical Field
The utility model relates to a leakage detecting device, in particular to a gas collecting device for a GIS gas leakage detector, belonging to the technical field of electrical facility detection.
Background
The insulation and arc extinguishing capability of gas media in sulfur hexafluoride electrical equipment mainly depends on purity and pressure, and once gas leaks, the safety operation of the equipment and the personal safety of personnel are directly influenced. The annual air leakage rate of each air chamber in the apparatus cannot exceed 1% according to the relevant regulations. At present, leak detection is mainly divided into qualitative leak detection and quantitative leak detection, wherein the quantitative leak detection mainly comprises a pressure drop method and a bundling method. The depressurization method is suitable for measuring the gas leakage rate during operation or when the gas leakage is large, but cannot be measured due to sensitivity limitation in the case of a small gas leakage. The packing method adopts a plastic film to seal and pack the equipment joint and the pipeline joint so as to collect leaked gas, then carries out sulfur hexafluoride concentration detection according to the volume of a packing space and the packing time, and finally calculates the gas leakage rate. The method has the problems of inconvenient binding and inaccurate measurement of the volume of a binding space, and the air leakage rate still cannot be accurately measured. There is therefore a need for improvements in the prior art.
Disclosure of Invention
The utility model provides a gas collecting device for a GIS gas leak detector, which aims to solve the problems of inconvenience in binding, inaccurate measurement of the volume of a binding space and the like in a used binding method during gas leakage rate detection of existing sulfur hexafluoride gas equipment.
The utility model is completed by the following technical scheme: the utility model provides a gas collecting device that GIS gas leak detector used, its characterized in that it includes two buckles that the interval set up, locates the seal membrane between two buckles, wherein:
each buckle comprises two semicircular rings, horizontal plates are arranged on two sides of each semicircular ring respectively, a longitudinal through hole is formed in each horizontal plate, and a bolt with a nut is arranged in each longitudinal through hole;
the two sealing films are respectively arranged on the outer sides of the two buckles and between the two buckles, and clamping grooves, protruding strips and zippers for sealing are arranged at the connecting edges of the two sealing films, so that a gas collecting cavity is formed on the inner sides of the two sealing films between the two buckles;
so as with two buckle cover on waiting to detect the pipe connection mouth, collect gas through the inboard gas collection chamber of seal membrane, then remove the zip and open the seal membrane, insert the intubate of connecting the gas leakage detection instrument, can carry out concentration detection to the gas of collecting through the gas leakage detection instrument to obtain the gas leakage volume.
The semicircular inner wall of the buckle and the inner side of the horizontal plate are respectively provided with a sealing glue layer for preventing air leakage between the buckle and the pipe wall, so that the inner sides of two sealing films between the two buckles form a closed gas collecting cavity.
The draw-in groove, sand grip and the zip of sealed usefulness that two seal membrane connection edges were established each other are conventional product to make things convenient for the connection of two seal membranes, remove the intubate that the zip is convenient for insert the connection gas leak detection instrument simultaneously.
The utility model has the following advantages and effects: adopt above-mentioned scheme, can conveniently overlap two buckles on waiting to detect the pipe connection, collect gas through the inboard gas collection chamber of seal membrane, then remove the zip and open the seal membrane, insert the intubate of connecting the gas leak hunting instrument, can carry out concentration detection to the gas of collecting through the gas leak hunting instrument to obtain the gas leakage volume. Not only simple to operate, the gas collection chamber volume is fixed and the leakproofness is strong moreover, can accurate calculation gas leakage volume. Is an ideal gas collecting device.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
The utility model provides a gas collecting device for a GIS gas leak detector, which comprises a left buckle 1 and a right buckle 1 which are arranged at intervals, and a sealing film 3 arranged between the two buckles 1, wherein:
each buckle 1 comprises an upper semicircular ring 11 and a lower semicircular ring 11, horizontal plates 12 are respectively arranged on two sides of each semicircular ring 11, a longitudinal through hole is formed in each horizontal plate 12, a bolt 13 with a nut is arranged in each longitudinal through hole, the upper semicircular ring 11, the lower semicircular ring 11 and the horizontal plates 12 are connected through the bolt 13 with the nut to form a hoop with the circular rings, and the circular rings are sleeved on the outer wall of the pipeline 5;
the two sealing films 3 are respectively arranged on the outer sides of the left buckle 1 and the right buckle 1 and between the left buckle 1 and the right buckle 1, and a clamping groove, a convex strip 2 and a zipper 4 for sealing are arranged at the connecting edge of the two sealing films 3, so that a gas collecting cavity is formed on the inner side of the two sealing films 3 between the two buckles 1;
and sealing glue layers 6 are respectively arranged on the inner wall of the semicircular ring 11 of the buckle 1 and the inner side of the horizontal plate 12.
During operation, overlap two buckle 1 on the 5 interfaces of pipeline that wait to detect, collect gas through the inboard gas collection chamber of seal membrane 3, then remove zip 4 and open seal membrane 3, insert the intubate of connecting the gas leak hunting instrument (because conventional equipment, so do not give in the picture), can carry out concentration detection to the gas of collecting through the gas leak hunting instrument to obtain the gas leakage volume.
