Abstract
The utility model discloses a single-item superscalar processing system for humidity of insulating gas in a sulfur hexafluoride switch. The processing system comprises a switching valve, a filter, activated alumina, a molecular sieve, a compressor, a pressure stabilizing valve, a purification tank and a gas pump which are sequentially connected from left to right through a pipeline. The processing system further comprises a vacuum pump, wherein one side of the vacuum pump is connected onto the pipeline between the switching valve and the filter, and the other side of the vacuum pump is connected on the pipeline between the purification tank and the gas pump. According to the processing system, a high-precision processor is formed by the filter, the activated alumina and the molecular sieve, and three-chamber-in-series dehumidification is formed, so that the insulating gas with unqualified humidity in the sulfur hexafluoride switch can be subjected to on-site quick processing, the humidity indicator of sulfur hexafluoride gas is recovered to a qualified state, and the required good insulating property of the sulfur hexafluoride gas is guaranteed; and meanwhile, adverse reactions, such as hydrolysis, corrosion and the like, participated by moisture in electrical equipment are interrupted, so that the safe operation of the electrical equipment is guaranteed.
Description
Technical field
The utility model relates in a kind of switch the sulfur hexafluoride gas humidity individual event treatment system that exceeds standard.
Background technology
Sulfur hexafluoride gas is a kind of nontoxic but gas with good insulation performance replaces traditional insulating oil to be used for electrical equipments such as switch, combined electrical apparatus at present, plays insulating effect.Electric switch is in installation, gas replenishment process, factors such as, gas replenishment process imprecision moist because of device interior spare, moisture is entered in the apparatus for sealing, cause the paranormal standard value of sulfur hexafluoride insulating gas humidity, can reduce the insulating properties of electrical equipment like this, cause equipment corrosion when serious, impel sulfur hexafluoride catabolite generation hydrolysis simultaneously, increased the component and the content of toxicity, harmful substance.At present, split the sulfur hexafluoride gas that Central Shanxi Plain humidity exceeds standard and adopt the method that more renews gas, what change exceeds standard gas storage in steel cylinder, is transported to the unified processing in sulfur hexafluoride recycling center or adopts large-scale recycling car, can make the duration delay, increase economic the input like this.
The utility model content
The technical problems to be solved in the utility model provides a kind of humidity treatment system that can carry out on-the-spot fast processing to the sulfur hexafluoride gas humidity individual event problem of exceeding standard, and its structure is simpler, easy to operate, efficient is high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the insulating gas humidity individual event treatment system that exceeds standard in a kind of sulphur hexafloride circuit breaker, its key technology is: comprise the switching valve that from left to right is linked in sequence by pipeline, filter, activated alumina, molecular sieve, compressor, pressure maintaining valve, purification pot and air pump, described treatment system also comprises a vavuum pump, described vavuum pump one side is connected on the pipeline between switching valve and the filter, opposite side is connected on the pipeline between purification pot and the air pump, described filter, activated alumina and molecular sieve constitute high polisher.
Adopt the beneficial effect that technique scheme produced to be: the filter in the utility model, activated alumina and molecular sieve are formed high polisher, form the series connection dehumidifying of three Room, can carry out on-the-spot fast processing to the insulating gas in the underproof sulphur hexafloride circuit breaker of humidity, make the sulfur hexafluoride gas humidity index return to eligible state, guaranteed the good insulation performance performance that it should have, interrupt abominable reaction such as the hydrolysis that moisture participates in, corrosion simultaneously in equipment, guaranteed the safe operation of electrical equipment.The utility model need not more renew gas, can raise the efficiency, and reduces cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein, 1, switching valve; 2, filter; 3, activated alumina; 4, molecular sieve; 5, compressor; 6, pressure maintaining valve; 7, purification pot; 8, vavuum pump; 9, air pump.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1, structure of the present utility model is: it comprises switching valve 1, filter 2, activated alumina 3, molecular sieve 4, compressor 5, pressure maintaining valve 6, purification pot 7, air pump 9 that from left to right is linked in sequence successively by pipeline and the vavuum pump 8 that acts on whole system, and described purification pot 7 will be handled qualified insulating gas by air pump 9 and recharge to device interior.Vacuumize with 8 pairs of whole systems of vavuum pump before the gas treatment, vacuum is reached more than the 1Torr, make failure gas enter system by switching valve 1, gas flow through the series connection filter 2 remove solid decomposer and part moisture, remove most of moisture and portion gas analyte through activated alumina 3 then, remove residual moisture and remain most gas analyte through molecular sieve 4 again and obtain dry pure sulfur hexafluoride gas, compress after pressure maintaining valve 6 is delivered to storage temporarily in the purification pot 7 by compressor 5 sulfur hexafluoride gas that drying is pure, wherein the effect of pressure maintaining valve 6 is to guarantee that the compressor power output is stable, utilizes air pump 9 that the gas in the purification pot 7 is sent into equipment when recharging gas.
