One of main project of examination and in-service surveillance is connect, the leakage rate per year of each air chamber is no more than 0.5% in equipment；Prior art
In, SF6 seepage gas collection modes can not react air leakage well；It is this to be let out as caused by sealing surface in process of the test
Leakage is typically carried out with bandaging strapping, and its method is to carry out closing bag to the bump joint of equipment, pipe joint etc. with clinker film
Prick to collect gas leakage, and measure or estimate the volume in wrapping space, through after a period of time, being measured and being wrapped with quantitative leak detector
The SF6 gas concentrations pricked in space, then calculate the absolute leak rate of air chamber；During wrapping, the general plastics thick with about 0.1mm are thin
Film makes a circle half by the geometry of joint, makes seam upwards, constitute as far as possible it is circular or square in order to estimate volume, through whole
Tape is tightened or with adhesive tape along edge adhesive seal after shape；Plastic sheeting keeps certain distance, general 5mm with joint surface
Left and right；After wrapping, measured typically in 24h, although this test method can be good at detecting joint whether gas leakage, but
The gas flow measured in 24h internal leakages that can not be exactly accurate, reason is that the wrapping space body to be formed is wrapped up with plastic sheeting
Product is not easy to estimate, and because the joint at scene is many and not of uniform size, due also to various live actual causes, the system of leading can not
The volume in estimation wrapping space；Further, since absorption and the osmosis of difference variation and plastic sheeting, can cause to wrap up space
Immesurable change occurs for interior SF6 gas concentrations, influences the accuracy of measurement；For more accurate measurement SF6 gas permeations
Amount, the progress for facilitating leak test to work, it is ensured that the person, power network, equipment safety is badly in need of developing a kind of SF6 seepages gas collection
Device.

It is used as the utility model further scheme：The delivery line is pvc pipe, a diameter of 2mm of delivery line.
It is used as the utility model further scheme：The storage system be length × width × height=100mm × 100mm ×
100mm square.
It is used as the utility model further scheme：Being provided with a diameter of 10mm of measured hole, measured hole is used for
Sealed self-adhering-type adhesive tape.
Compared with prior art, the beneficial effects of the utility model are：Collection system of the present utility model can be directed to
Different GIS producers model, different GIS interfaces design different length, big using flexibility ratio；Storage system does not produce interference gas
Body, it is lightweight, it is unlikely to deform, can repeatedly uses, and usage cycles are long；It is practical；Collection system is adopted with storage system
Delivery line two ends are arranged on fast plug, are easy to grafting, good airproof performance, light weight is durable；Provided with a diameter of on the downside of storage system
10mm measured holes, convenient leak detection instrument probe is deeply entered；Quantitative leak accuracy is high；SF6 gases are detected using the utility model
When, the volume of gas leakage can be accurately detected, the precision of SF6 gas tightness experiment is not only increased, also improves
Efficiency of construction, reduces workmen's quantity, shortens process and engineering time, also ensure that the person, power network, equipment safety；
