Abstract
The utility model discloses an SF6 gas recovering bag; the SF6 gas recovering bag comprises a sealed gas collecting bag, a gas guide hose and a gas guide hard tube; the gas guide hose is tightly connected with the gas collecting bag; the gas guide hose is connected with the gas guide hard tube by a connector; and a valve switch used for controlling the on-off of the gas guide hose is arranged on the gas guide hose. The SF6 gas recovering bag has the following beneficial effects that the SF6 gas outlet of a minim moisture testing apparatus of an SF6 breaker is tightly connected with the gas collecting bag via a gas guide tube, the SF6 gas flowing out during a testing process can be all recovered, and one gas collecting bag can meet the waste gas collecting amount of a large size transformer station, the SF6 gas recovering bag is convenient to use and operate, and the danger caused by directly exhausting the waste gas into air is avoided, thus the SF6 gas recovering bag is beneficial for environment protection.
Description
Technical field
The utility model relates to a kind of SF6 gas recycling bag, is applicable to the gas sampling technical field in the circuit breaker test process.
Background technique
The SF6 circuit breaker is with the circuit breaker of SF6 gas as arc extinguishing and insulating medium.It and air circuit breaker belong to gas-blast circuit breaker, and difference is: 1. operating air pressure is lower; 2. in the arc blow-out process, gas is discharged to atmosphere, and recycles in locking system.The insulation that SF6 gas is good and arc extinction performance, make the SF6 circuit breaker have following advantage: connecting-disconnecting function is strong, fracture voltage is suitable for doing highlyer, allow continuous open and close times more, be applicable to frequent operation, noise is little, without fire peril, dynamo-electric wearing and tearing are little etc., are " without maintenance " circuit breakers of a kind of excellent performance.
Existing high voltage substation adopts the SF6 circuit breaker mostly, and these circuit breakers will carry out routine test.There is a SF6 gas that needs to take out in circuit breaker to detect in test event.Original test method is in test process, and test SF6 gas later directly is discharged in atmosphere.And the SF6 gas after operation a period of time can produce multiple poisonous and hazardous gas, and these gases not only threaten tester's safety, and very serious greenhouse effect are arranged, and can produce a lot of harm so the SF6 gas after testing directly enters atmosphere.So the SF6 gas that circuit breaker was tested reclaims necessary.
The model utility content
Technical problem to be solved in the utility model is to provide and a kind ofly prevents that the SF6 gas that produces in the circuit breaker test process from directly entering the SF6 gas recycling bag of atmosphere, is conducive to environmental protection.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of SF6 gas recycling bag, comprise gas collection bag, soft air-guide pipe and the air guide hard tube of sealing, described soft air-guide pipe and gas collection bag are tightly connected, and soft air-guide pipe is connected with the air guide hard tube by connecting head.
Described soft air-guide pipe is provided with for controlling soft air-guide pipe and closes valve switch with conducting.
Described soft air-guide pipe is polyfluortetraethylene pipe.
Described connecting head is threaded pipe, and its two ends are tightly connected with soft air-guide pipe, air guide hard tube respectively.
When SF6 gas recycling bag described in the utility model be used for is reclaimed the SF6 gas that the little water test instrument of SF6 circuit breaker test process produces, at first the movable end with the air guide hard tube is connected with the air outlet of breaker tester device, opens valve switch and begins the SF6 gas that test process produces is collected; Be completed, then the throttle down switch disconnects being connected of air guide hard tube and test instrument.
The beneficial effect that adopts technique scheme to produce is: the SF6 gas outlet of breaker tester device is connected with the gas collection bag is airtight by air pipe; can be with the SF6 gases with total recovery that produces in test process; and a gas collection bag can satisfy the gas sampling amount of a large-scale substation; use easy to operate; prevent that waste gas from directly entering the harm that atmosphere causes, and is conducive to environmental protection.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Wherein, 1, the gas collection bag, 2, soft air-guide pipe, 3, valve switch, 4, connecting head, 5, air guide hard tube.
Embodiment
Embodiment as shown in Figure 1 as can be known, SF6 gas recycling bag described in the utility model is characterized in that, comprises gas collection bag 1, soft air-guide pipe 2 and the air guide hard tube 5 of sealing, described soft air-guide pipe 2 is tightly connected with gas collection bag 1, and soft air-guide pipe 2 is connected with air guide hard tube 5 by connecting head 4.
Described soft air-guide pipe 2 is provided with for controlling soft air-guide pipe 2 and closes valve switch 3 with conducting.
Described soft air-guide pipe 2 is polyfluortetraethylene pipe.
Described connecting head 4 is threaded pipe, and its two ends are tightly connected with soft air-guide pipe 2, air guide hard tube 5 respectively.
When above-mentioned SF6 gas recycling bag be used for is reclaimed the SF6 gas that the circuit breaker test process produces, at first the movable end with air guide hard tube 5 is connected with the air outlet of breaker tester device, opens valve switch 3 and begins the SF6 gas that test process produces is collected; Be completed, then throttle down switch 3 disconnects being connected of air guide hard tube 5 and test instrument.
The utility model is connected by air pipe the SF6 gas outlet of breaker tester device with the gas collection bag is airtight; can be with the SF6 gases with total recovery that produces in test process; and a gas collection bag can satisfy the gas sampling amount of a large-scale substation; use easy to operate; prevent that waste gas from directly entering the harm that atmosphere causes, and is conducive to environmental protection.
