A pressure sensor and its control circuit display panel are installed in front of the gas buffer tank. The onsite small-volume recovery device is a movable type, is used at low cost, is convenient to use, is convenient to carry, is easy to recover trace gases rapidly and is convenient for onsite overhauling and maintenance.
Description
Technical field
The present invention relates to a kind of instrument, particularly the on-the-spot stingy amount retracting device of a kind of sulfur hexafluoride electrical equipment.
Background technology
In recent years, along with the continuous renewal of socioeconomic development and power equipment technology, newly-built transformer station and old transformer station technological transformation sulfur hexafluoride (SF6) electrical equipment came into operation in enormous quantities.Because sulfur hexafluoride (SF6) gas has remarkable electrical insulating property and arc quenching characteristic, in power industry, by the extensive dielectric as electrical equipments such as switches, used, SF6 gas conduct-kind of good insulation and the application of arc-extinguishing medium in High-Voltage Electrical Appliances field are increasingly extensive, replaced traditional oil-break, oily current transformer, sulfur hexafluoride voltage transformer, sulfur hexafluoride gas combined electrical apparatus have also obtained faster and have applied.
Also there are a lot of drawbacks in SF6 gas: SF6 catabolite has severe toxicity, the not environmental protection of SF6 gas, SF6 gas cost higher, SF6 gas is entered to air large to ambient influnence, also can cause very large waste.
In the Kyodo Protocol book of control global warming in 1997, SF6 gas is listed in one of 6 kinds of greenhouse gases.Mainly because SF6 gas has sizable potential danger to greenhouse effects: SF6 molecule is CO2 on the impact of greenhouse effects 23500 times; SF6 gas is discharged into after atmosphere, and the life-span is about 3400.The sulfur hexafluoride electrical equipment gas of operation enters atmosphere can make staff directly in the face of SF6 gas decomposition product, and SF6 gas decomposition product is healthy because of its toxicity and corrosivity serious threat field personnel's.
Sulfur hexafluoride gas retracting device generally all more than hundreds of thousands unit, expensive and bulky heaviness.At present domestic also do not have one to produce small-sized SF6 measurement device for recovering tail gas, solves the sulfur hexafluoride gas emission problem after test.Adopting SF6 to measure device for recovering tail gas can be the SF6 gas storage after measuring in special-purpose recovery steel cylinder, solved the shortcoming that sulfur hexafluoride gas enters air, extremely meet environmental requirement, the sulfur hexafluoride gas being simultaneously stored in special-purpose recovery steel cylinder can also, by recycling after processing, have good economic benefit and social benefit.
Summary of the invention
Object of the present invention will overcome the above problems exactly, provide a kind of movably sulfur hexafluoride electrical equipment on-the-spot stingy amount retracting device, SF6 gas is being detected to the waste gas producing, both can realize device security was detected fast, abundant recovery and reuse SF6 gas, reduces the destruction of gas to the injury of health of human body and atmospheric environment again; Fund input is little, and simple structure is easy to use.
Technical scheme of the present invention is achieved like this: the on-the-spot stingy amount retracting device of a kind of sulfur hexafluoride electrical equipment, be characterized in: comprise the recovery go-cart of large diameter wheel, gas storage cylinder that external gas recovery uses and gas surge tank, aspiration pump, oilless (oil free) compressor, gs-oil separator and three-way valve, sulfur hexafluoride device-specific switching device are installed reclaiming in go-cart; Pressure sensor and control loop display floater thereof are housed before gas buffer tank.
The present invention adopts portablely, and cost is low, easy to use, be easy to carry; Be easy to reclaim fast minimum gas, be convenient to site examining and repairing and maintenance.

The specific embodiment
As seen from Figure 1: the present invention includes the recovery go-cart of large diameter wheel, gas storage cylinder that external gas recovery uses and gas surge tank, aspiration pump, oilless (oil free) compressor, gs-oil separator and three-way valve, sulfur hexafluoride device-specific switching device are installed reclaiming in go-cart; Pressure sensor and control loop display floater thereof are housed before gas buffer tank.
Described control loop display floater comprises fuse, power supply indicator, RCCB, pressure sensor control loop, control loop controls aspiration pump and oilless (oil free) compressor starts, keep test mode to carry out under an atmospheric pressure, improve compressor performance, improve the pressure that reclaims steel cylinder, strengthen recovery ability, on recovery go-cart top, the power supply for tester is housed, be convenient to the movement of retracting device working site.
The present invention can detect sulfur hexafluoride gas discharge automatically, by aspiration pump, sulfur hexafluoride gas is extracted in special-purpose compression pump, after oilless (oil free) compressor supercharging, is directly poured into and reclaims in steel cylinder, when the pressure of returnable bottle reaches setting value, automatic-prompting is changed and is reclaimed gas cylinder.
After detecting instrument is measured sample gas, sample gas is discharged through gas outlet, by this air chamber, the gas outlet of instrument is connected with recovery system, gas is divided into two-way, a road offers booster pump as driving pressure, reclaim on one tunnel, be responsible for the tail gas after measuring to reclaim, major function is by the Impurity removal in the gas reclaiming, by the gas boosting reclaiming in storage steel bottle, be used for depositing the gas of recovery, automatic control loop is used for controlling whole system.There is no at present same type operating system, as special design production capital drops into larger.Therefore this sulfur hexafluoride gas cylinder heating device has the advantages such as economic, practical, stable, reliable, has very strong actual application value and promotional value.
In Fig. 1, parts are described as follows:
1) instrument: detecting instrument is discharged by gas outlet after sample gas is measured.
2) air chamber: the gas outlet of instrument is connected with recovery system by this air chamber.
3) threeway: gas is divided into two-way, and a road offers booster pump as driving pressure, and reclaim on a road.
4) aspiration pump: be responsible for the tail gas after measuring to reclaim.
5) gs-oil separator: major function is by the Impurity removal in the gas reclaiming.
6) booster pump: by the gas boosting reclaiming in storage steel bottle.
7) steel cylinder: the gas that is used for depositing recovery.
8) circuit board: be used for controlling whole system.
