Description
Technical field
The present invention relates to gas monitor apparatus field, in particular to a kind of gas leakage monitoring system.
Background technology
Along with the Development of Urbanization of China, big city population is more intensive, and skyscraper stands in great numbers, and power consumption sharply increases,
Number transformer is also being continuously increased, and traditional Large Copacity oil-filled transformer oil mass is big, once catches fire because of fault, will be to high level
The security of the lives and property of building and people constitutes serious threat.Therefore, six-component force balance transformator is in the sixties in last century
Obtain a wide range of applications in Urban Underground transformer station of China afterwards, compare with traditional filling transformer, SF6Transformator has bright
Aobvious advantage: due to SF6Non-combustible and the most combustion-supporting property of gas, SF6Gas does not has the potentially possible of fire, and noise is low, especially
It is suitable for using in bustling commercial center and densely populated residential block.
SF6Although gas-insulated performance is superior, but, it must be carried out strict quality prison according to relevant regulatory requirements
Superintend and direct and safety management.This is because SF6Gas is in its production process or under the effect of the high energy factor, if generation can be decomposed
Dry poisonous even severe toxicity, severe corrosive objectionable impurities, when there is moisture, air (oxygen), electrode material, equipment and materials in system
Deng, then can cause the complication of catabolic process, cause the value volume and range of product of catabolite substantially to increase, its hazardness significantly adds
Greatly.
Due to reasons such as six-component force balance transformer manufacturing quality, mounting process, aging, the blowing pressures of potted component,
SF in six-component force balance transformator6The leakage of gas is difficult to avoid that.Six-component force balance transformator once leaks
Fault, its interior sulfur hexafluoride gas will substantial amounts of escape, the SF leaked out6Gas and analyte thereof are empty at indoor low layer
Between gather, cause ischaemia and band poison, to entering indoor maintenance and the healthy of the personnel of tour constitutes serious infringement.Therefore,
SF accurately and effectively is installed6Gas monitor apparatus, contributes to taking emergent maintenance measure in time, it is to avoid cause the person and secondary wound
Evil.
The power industry relevant criterion of China proposes strict prison to the indoor environment of sulfur hexafluoride insulation electrical equipment
In case there is serious accident in control measure.Such as " electric power safety working regulation " (power plant and transformer station's electric part) and DL/T
639-1997 " sulfur hexafluoride electrical equipment runs, tests and maintainer's security protection detailed rules and regulations " special provision, indoor fill SF6
During gas, SF in the air of working area6Gas content must not exceed 1000 μ L/L, in addition to need to installing sharp draft device, it is necessary to
SF is installed6Gas leakage online monitoring alarm system, provides health of human body safeguard protection for staff.
SF6When instantaneous leak amount is bigger, SF6Content will be in higher state in 0.5～3m altitude range for a long time,
If the most only install SF on horizontal earth's surface6Sensor, it is impossible to effectively monitoring SF in a large amount of leakage time spaces6Distribution.
Summary of the invention
