Description
Technical field
Utility model relates to a kind of environmental protection equipment, is specifically related to a kind of retracting device of GIS combined electrical apparatus SF6 gas.
Background technology
SF6 is a kind of gas with excellent insulation property and arc extinction performance, show according to interrelated data, the annual SF6 gas in the whole world is used for power industry high pressure electrical equipment more than 80%, in high pressure electrical equipment, the tolerance of GIS (GIS-Geographic Information System) usefulness is maximum, the GIS combined electrical apparatus is when removing replacing, if not reclaiming, a large amount of SF6 gas directly is not put in the air, can damage the ozone layer, produce greenhouse effect and make global warming, and SF6 gas individual molecule is 25000 times of carbon dioxide to the influence of greenhouse effect, through the SF6 gas of operation, the circuit breaker storehouse of particularly cut-offfing short circuit current is under the high arc temperature effect, can decompose poisonous chemical solid matter and gas, in case the human body contact can cause poisoning; And the SF6 gas that reclaims can continue to use after qualified through chemical examination, and 50 kilograms SF6 gas (steel cylinder) needs the RMB more than 8000 yuan, can save a large amount of energy and fund like this.
Summary of the invention
The purpose of this utility model provides a kind of retracting device of GIS combined electrical apparatus SF6 gas, and this apparatus structure is simple, and is easy to use, can reclaim SF6 gas safely.
A kind of retracting device of GIS combined electrical apparatus SF6 gas, comprise pipe joint, air compressor, high-pressure cylinder, spring balance, wherein a pipe joint is connected between SF6 charging and discharging valve and the air compressor, another pipe joint then is connected between air compressor and the high-pressure cylinder, and high-pressure cylinder is fixed on the pan of a steelyard of spring balance.
Wherein air compressor is located on the chassis, and spring balance is affiliated in the chassis side, and spring balance is provided with chain, and high-pressure cylinder is fixed on the pan of a steelyard.
This apparatus structure is simple, and is easy to use, can reclaim SF6 gas safely, and recovery speed is fast, the coefficient of safety height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the retracting device of a kind of GIS combined electrical apparatus SF6 gas of the present utility model.
Fig. 2 is the structural representation of the retracting device spring balance of a kind of GIS combined electrical apparatus SF6 gas of the present utility model
Embodiment
Shown in Figure 2 as Fig. 1, a kind of retracting device of GIS combined electrical apparatus SF6 gas, comprise pipe joint, air compressor 2, high-pressure cylinder 3, spring balance 4, wherein a pipe joint 11 is connected between SF6 charging and discharging valve and the air compressor 2,12 of another pipe joints are connected between air compressor 2 and the high-pressure cylinder 3, and high-pressure cylinder 3 is fixed on the pan of a steelyard 41 of spring balance 4.Wherein air compressor 2 is located on the chassis 21, and spring balance 4 is affiliated in chassis 21 sides, and spring balance 4 is provided with chain 42, and high-pressure cylinder 3 is fixed on the pan of a steelyard 41.The SF6 gas that reclaims must be done toxicity test and little water test, prevent to mix at recovery fashion gas and waste gas, must prepare enough high-pressure cylinder, pressure-reducing valve, connecting tube and joint etc. simultaneously, these high-pressure cylinders 3 and connecting tube will carry out drying with highly purified nitrogen; Bad because of sealing in order to prevent equipment during recovery, the SF6 gas leakage is in the hyperbaric chamber, so must open the ventilation blower 30 minutes in hyperbaric chamber, the staff has worn gas mask and gloves enter the hyperbaric chamber then, and SF6 gas is carried out following recovery operation.The SF6 charging and discharging valve of ready pipe joint 11 1 ends and equipment is connected, and the other end is connected with the air inlet of air compressor 2.The gas outlet of another pipe joint 12 1 ends and air compressor 2 is connected, and the other end is connected with outage compressed steel bottle 3.At this moment in SF6 gas fills into the sky steel cylinder along charging and discharging valve, pipe joint 11, the air inlet of air compressor 2, the pressure tank of air compressor 2, the gas outlet of air compressor 2, the pipe joint 12 in GIS gas storehouse, during recovery the valve of GIS and high-pressure cylinder 3 valve opens, because the pressure of equipment is greater than the air pressure of high-pressure cylinder 3, so SF6 gas is to high-pressure cylinder 3 inflations.When pressure is in balance, start air compressor 2 motors, the SF6 of equipment is extracted into air compressor 2 compression cylinders, when the pressure of pressure greater than steel cylinder, compression cylinder is to pneumatic inflation, automatic like this bleeding repeatedly inflated till steel cylinder is full of, increase along with the SF6 gas pressure in the steel cylinder, SF6 gas can generate heat, and the pressure of high-pressure cylinder 3 arrives the peak of 2.5Mpa soon, in case high-pressure cylinder 3 temperature of pressurization are higher than 10 ℃ of ambient temperatures, must temporarily stop to reclaim, the steel cylinder of changing other reclaims, and treats to reclaim when high-pressure cylinder 3 temperature drop to ambient temperature again.. when reclaiming pressurization once more, high-pressure cylinder 3 is fixed on the special-purpose pan of a steelyard, observes the weight of the SF6 gas of 3 li of high-pressure cylinders while filling, as long as weight reaches 45 kilograms, just stop to reclaim (noticing that pressure can not surpass 2.5Mpa).The actual weight of big high-pressure cylinder 3 every bottle of SF6 gases is 50 kilograms, in order to guarantee safety, is controlled at when we reclaim about 45 kilograms, and whether just can understand steel cylinder exactly with the method that weighs sufficient.Adopt above method both to guarantee that steel cylinder was full of SF6 gas, can not cause danger again because of pressure is too high.Owing to changed the recovery operational method, speed obviously improves, and assurance second stage dismounting work is carried out as scheduled.
Claims (2)
1, a kind of retracting device of GIS combined electrical apparatus SF6 gas, it is characterized in that: comprise pipe joint, air compressor, high-pressure cylinder, spring balance, wherein a pipe joint is connected between SF6 charging and discharging valve and the air compressor, another pipe joint then is connected between air compressor and the high-pressure cylinder, and high-pressure cylinder is fixed on the pan of a steelyard of spring balance.
2, the retracting device of a kind of GIS combined electrical apparatus SF6 gas according to claim 1, it is characterized in that: wherein air compressor is located on the chassis, and spring balance is affiliated in the chassis side, and spring balance is provided with chain.
