Abstract
The invention discloses a rapid vacuum pumping and gas filling recycling connecting device, a vacuum pumping method and a gas filling method. The rapid vacuum pumping and gas filling recycling connecting device comprises a cross connecting body and an SF6 equipment connecting piece used for connecting with SF6 equipment, wherein the cross connecting body comprises a cross pipe, connecting pipes, two connecting groove pieces, two connecting plugs and two ball valves; the cross pipe comprises four outlet ends; the first outlet end is connected with a first ball valve; the first ball valve is connected with a first connecting groove piece through the connecting pipe; a second outlet end is connected with a second connecting groove piece; a third outlet end is connected with a first connecting plug; a fourth outlet end is connected with a second ball valve; the second ball valve is connected with a second connecting plug through the connecting pipe. The rapid vacuum pumping and gas filling recycling connecting device, the vacuum pumping method and the gas filling method have the advantages that the universality is good, the connection and operation are simple, fast and convenient, and pipelines can be protected from damp.
Description
Technical field
The present invention relates to a kind of rapid vacuumizing and inflation and reclaim connection set, especially a kind ofly be applicable to rapid vacuumizing and inflation that electric substation's SF6 equipment vacuumizes or inflate and reclaim connection set, vacuum pumping method and inflation method.
Background technique
Electric substation trends towards without the oiling development at present, and electric substation's inner breaker mostly is vacuum circuit breaker, SF
6circuit breaker, wherein SF
6the insulating property that breaker apparatus is good with it, corrosion protection and nontoxic performance have occupied the breaker apparatus leading position more than 35kV.Along with SF
6application development, gas-filled type rheology the universal and GIS of electric substation the extensive use of HGIS, SF6 inflation, gas reclaim, the test of micro-water all needs the inflation/deflation connection set.
Use existing SF
6mainly there is following problem in filling apparatus venting connection set:
1) existing SF
6filling apparatus means of deflation model is many, all kinds of numerous and diverse, the product joint that different manufacturers is produced can not be general, even same producer also adopts the joint of different model sometimes, inflation/deflation joint, the pipeline of different manufacturers installed, overhauls, need to be carried while testing to each equipment, is not easy to the repair and maintenance of equipment;
2) adopt of the existing joint used is threaded more, and the sealing gasket Reusability easily damages, loses, and joint easily leaks gas, can not reach the sealing effect that vacuumizes requirement, part clamping pipeline and inipple coordinate bad, and connection device wants the connecting leg road to rotate together, wastes time and energy;
3) existing SF
6the gas ducting thickness that the filling apparatus means of deflation is used differs, and quality differs greatly, and some producers even replace with the plastics oxygen hose, and a lot of crackles of microscler one-tenth of time one, cause potential safety hazard;
4) in addition, general producer gas ducting is not all sealed, and while depositing after use, easily makes moist, and while re-using, easily brings the moisture in pipeline into SF
6equipment, make SF
6apparatus insulated level descends accidents caused.
Summary of the invention
The present invention is the deficiency existed in above-mentioned prior art for avoiding, and provides a kind of rapid vacuumizing and inflation to reclaim connection set, vacuum pumping method and inflation method, so that SF
6equipment in the situation that do not change existing interface, realizes that total interface is general, fills, atmospheric pipe is provided with selfsealings, guarantees to fill, atmospheric pipe inside is isolated from the outside, and prevents that pipe interior from making moist.
The present invention be the technical solution problem by the following technical solutions.
Connection set is reclaimed in rapid vacuumizing and inflation, and its structural feature is, comprise the cross connecting body and for SF
6the SF that equipment is connected
6the equipment connection part; Described cross connecting body comprises cross tee, connecting tube, two connections slotware, two attachment plugs and two ball valves; Described cross tee includes four outlet end, and described four outlets are respectively the first outlet end, the second outlet end, the 3rd outlet end and the 4th outlet end; Two connection slotwares are respectively the first connection slotware and are connected slotware with second, and described two attachment plugs are respectively the first attachment plug and the second attachment plug, and described two ball valves are respectively the first ball valve and the second ball valve;
Described the first outlet end is connected with described the first ball valve, and described the first ball valve is connected slotware by connecting tube and described first and is connected; Described the second outlet end and described second is connected slotware and is connected; Described the 3rd outlet end is connected with described the first attachment plug; Described the 4th outlet end is connected with described the second ball valve, and described the second ball valve is connected with described the second attachment plug by connecting tube.
The structural feature that connection set is reclaimed in rapid vacuumizing of the present invention and inflation also is:
Described connection slotware and attachment plug are stainless steel and make.
Described SF
6the equipment connection part comprises a connecting hose and is connected in the joint at described connecting hose two ends.
The present invention also provides a kind of vacuum pumping method that utilizes above-mentioned rapid vacuumizing and inflation to reclaim connection set, comprises the steps:
Step 1: by described rapid vacuumizing and inflation, reclaim connection set by vacuum pump and SF
