Description

A kind of GIS device gas leaks powered pressurized leaking stoppage method
Technical field
The present invention relates to a kind of gas leakage-stopping method of power system device maintenance, more particularly to a kind of GIS device Gas leaks powered pressurized leaking stoppage method.
Background technology
GIS (Gas Insulated Switchgear) is sulfur hexafluoride sealed combination electrical equipment, is to utilize SF6Gas is good Good insulating properties, breaker, disconnecting switch, earthed switch, transformer, arrester, bus, inlet-outlet sleeve, cable is whole End etc. is closely fitted together, and such occupation area of equipment is small, and advanced technology, maintenance workload is small, and operational reliability is high, It is used widely in power industry.But equipment is due to material, manufacturing process and installation, the gas of GIS device Body leakage problem is at home or even international all very universal.
It is to change in whole or in part currently for the conventional repair method of the GIS device that there is leakage, but this method Need for a long time to have a power failure equipment, even circuit, negative shadow can be produced to the safe and stable operation and social and economic benefits of power network Ring.Other conventional blocking methods also have:Repair welding method, steel band method, fixture injecting glue method, gluing connection.Wherein repair welding method is needed also exist for Charger, which has a power failure, to be depressured;Steel band method is only applicable to caliber identical pipe plugging, the leakage at caliber difference and flange position It can not use;Gluing connection is then directly to load onto equipment leakage position by using adhesive to realize leak stopping, due in equipment Sulfur hexafluoride has certain pressure, and adhesive solidification needs the time again, causes its success rate relatively low.Fixture injecting glue method need be customized Particular manufacturing craft simultaneously injects fluid sealant, fixture need customization, it is difficult to tackle catastrophic discontinuityfailure, and if leak stopping pump injection pressure is too high, It is also possible to expand leakage defect.So above-mentioned blocking method is not particularly suited for power system device service work.Therefore how to facilitate, The service work of leakage equipment is quickly completed under the conditions of with pressure has turned into the problem that power system is badly in need of solving.
《A kind of flow-guiding type Live leaking-stopping technology》(application number 201210087602.6) and《Water conservancy diversion bonding plugging type is with pressure Device for plugging》(application number 201410580187.7) with《A kind of sulfur hexafluoride electrical equipment gas leaks powered pressure sealing dress Put and method》The pressurized leaking stoppage method that (application number 201510586733.2) is introduced, is only limitted to sulfur hexafluoride electrical equipment local The processing that gas is leaked on point (such as trachoma), is leaked for large area, such as the gas leakage of weld seam, particularly crackle, flange face Leak stopping can not still be carried out.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of can realize and not had a power failure and convenient and swift large area is leaked and blocked up The GIS electrical equipment gas under-pressure leakage-plugging methods of leakage.
In order to solve technical problem, the GIS device gas that the present invention is provided leaks powered pressurized leaking stoppage method, including one Can annular be coated on GIS device leak position both sides Ω shapes rubber strip, one with blocking that described Ω shape rubber strips are connected Valve, a plurality of band by described Ω shape rubber strip colligations in GIS device, if in addition to dry adhesive, including following step Suddenly:
Step one:An aperture is opened in Ω shape rubber strips centre position, cut-out cock is fixedly secured in Ω shapes with adhesive Above the aperture of rubber strip, cut-out cock is opened;
Step 2:Clear up the filth of GIS device leak position annex;
Step 3:Adhesive coated is coated on GIS device leakage position in annular after the straight position of Ω shape rubber strips two ends Put both sides;
Step 4:Ω shape rubber strip joinings position is bonded using adhesive firm;
Step 5:Ω shape rubber strips two ends straight position is fixed in GIS device using band;
Step 6:After adhesive is fully cured, cut-out cock is closed, Process of Leaking Stoppage is completed.
Powered pressurized leaking stoppage method is leaked using the GIS device gas of above-mentioned technical proposal, its advantage is:Maintenance is deposited The GIS device leaked in large area is not required to be depressured or reclaim sulfur hexafluoride gas, using elastomeric material, without customizing metal pattern Tool, inspection operation is convenient, fast, also can quickly be removed during GIS device Disintegration overhaul, and the safe distance with powered position is allowing Under the conditions of can also carry out powered pressure sealing, saved the power system interruption maintenance time, improved the power supply reliability of power network.
In summary, the present invention be it is a kind of can realize do not have a power failure and convenient and swift large area leakage-stopping GIS device gas Body leaks powered pressurized leaking stoppage method.
