Abstract
The utility model relates to a gas filling device for electric power sulfur hexafluoride equipment, which comprises an SF6 filling cylinder, a gas cylinder pressure gauge, an output pressure gauge, an output valve, a gas filling tube communicated with the SF6 filling cylinder and a one-way gas nozzle positioned at the tail end of the gas filling tube. The gas filling tube is provided with a three-way tube. A breeches pipe of the three-way tube is provided with a control valve. The tail end of the breeches pipe of the three-way tube is communicated with an SF6 temporary storage cylinder. In the utility model, the gas filling tube is additionally provided with the three-way tube and the breeches pipe of the three-way tube is provided with the control valve, air in the gas filling tube is controlled to be firstly filled into the temporary storage cylinder so as to effectively avoid adding the air in the gas filling tube into the electric power SF6 equipment. The gas filling device for the electric power sulfur hexafluoride equipment can avoid SF6 being discharged into the atmosphere to pollute the environment, is favorable for recycling the SF6, has the advantages of small volume, low cost, simple, convenient and easy operation, convenient use and good effect and is very favorable for popularization and implementation.
Description
Technical field
The utility model relates to a kind of sulphur hexafluoride filling apparatus device of air, particularly relates to a kind of electric power sulphur hexafluoride filling apparatus device of air.
Background technique
SF
6Gas successfully is applied to high-voltage switch gear and equipment thereof as the insulation and the arc-extinguishing medium of excellence.Today, high pressure, ultrahigh pressure and extra-high voltage field, SF
6Gas almost becomes unique insulation and the arc-extinguishing medium of circuit breaker and GIS.At middle pressure field, SF
6Gas has become the two big pillars of running neck and neck with vacuum switch.SF
6Gas also constantly enlarges in the use in power transmission and transformation field, has obtained and use widely.
Pure new SF
6Gas is colourless, tasteless, odorless, do not fire, and stable chemical performance belongs to inert gas at normal temperatures.But in electric power system, because SF
6Gas mainly serves as insulation and arc-extinguishing medium, in circuit breaker or GIS breaking operation process, puts a little and under the factor affecting such as partial discharge, high temperature SF at scratch start effect, corona, spark
6Gas can decompose, and its analyte runs into programming corrosivity electrolyte, especially some high toxicity analyte behind the water, as SF

2F
2, S
2F
10, SOF
2, HF and SO
2, their Diazolidinyl Ureas, eyes, mucous membrane if intake is big, also can cause dizziness and pulmonary edema, even the causing death.
SF
6Gas still is one of six big greenhouse gases, electric power SF
6Equipment is when inflation, in order to discharge the air in the gas ducting, unavoidably with SF
6Gaseous emission in air, befouling environment.Referring to Fig. 1, because charging air inlet is a check valve, so when inflation, valve connects the switch inflation inlet, endotracheal air can not arranged, and can pour SF to air
6In the equipment air chamber.While electric power SF
6Equipment, when inflation, stuff discharge in the gas ducting and row are unclean, in the tonifying Qi process, exist air row unclean, can cause air to pour SF
6In the Switch main body, SF
6The degree of purity deficiency, arc quenching effect reduces, SF
6Little water exceeds standard, and will corrode the contact of switch, increases the D.C. resistance of switch, causes great influence for the normal operation of equipment.
Summary of the invention
The purpose of this utility model is to overcome deficiency and the defective that prior art exists, and provides a kind of air that prevents to add electric power SF
6The electric power sulphur hexafluoride filling apparatus device of air of equipment.
The technical solution of the utility model is a kind of electric power sulphur hexafluoride filling apparatus device of air, comprises SF
6The inflation gas cylinder, cylinder pressure gauge, delivery gauge and delivery valve, gas tube that is communicated with gas cylinder and the unidirectional valve that is positioned at the gas tube end are equipped with three-way pipe on gas tube, on the three-way pipe breeches pipe control valve is installed, the end of this three-way pipe breeches pipe and SF
6Temporary gas cylinder is communicated with.
Described three-way pipe is positioned at the gas tube end.
The utlity model has following beneficial effect, increasing three-way pipe on the gas tube and on the threeway breeches pipe, control valve is being installed, the inflation inner air tube is at first fed in the temporary gas cylinder, can effectively avoid the inflation inner air tube is added electric power SF by control
6In the equipment.Can avoid SF
6Gas enters the pollution of atmosphere environment.Help SF
6The recycling of gas.It is little to the utlity model has volume, and cost is low, easy to operation, and effective advantage easy to use is beneficial to promotion and implementation very much.
Description of drawings
Figure l is existing sulphur hexafluoride filling apparatus device of air structural representation;
Fig. 2 is the utility model sulphur hexafluoride filling apparatus device of air structural representation.
Embodiment
Embodiment one: referring to Fig. 2, and a kind of electric power sulphur hexafluoride filling apparatus device of air, SF
6Be separately installed with cylinder pressure gauge 4 on the inflation gas cylinder 1, delivery gauge 5 and delivery valve (be prior art, do not draw), label 3 is the gas cylinder charging air inlet.SF
6 Inflation gas cylinder 1 one sides are communicated with gas tube 2, and the end of this gas tube 2 is equipped with unidirectional valve 3.Simultaneously, on gas tube 2, be provided with breeches pipe or three-way pipe is installed, control valve 8 is installed, the end of this three-way pipe breeches pipe 7 and SF on the three-way pipe breeches pipe 7 near unidirectional valve position
6Temporary gas cylinder (not shown) is communicated with.
Above-mentioned unidirectional valve 3 and SF
6The switch inflation inlet of equipment cooperates, and opens delivery valve (or output gas meter valve), SF
6Gas enters gas tube through gas meter, and because of charging air inlet is a check valve, during control valve 8, the inflation inner air tube only enters sky SF on opening breeches pipe
6The gas cylinder harvesting, closed control valve 8 then, open SF
6Valve on the equipment is to SF
6Equipment is inflated, and has so just prevented that malaria from entering SF
6Equipment air chamber and SF
6Gas enters the pollution of air-air.The air and the SF of harvesting
6Mixed gas can be by SF
6Gas generation producer reclaims, and re-uses after treatment.
