Technical field
The utility model relates to the gas controlling device technical field, especially a kind of sulfur hexafluoride gas leak supervision warning device.
Background technology
SF6---sulfur hexafluoride gas is used widely in electric system with the insulation and the arc extinction performance of its excellence.In today, SF6 gas almost becomes insulation and arc-extinguishing medium unique among high pressure, extra high voltage circuit breaker and the GIS (combined electrical apparatus).Pure SF
6Gas is colourless, tasteless, odorless, do not fire, at normal temperatures stable chemical performance.But in disjunction operating process such as isolating switch, switch, under factors such as electric arc, corona, spark discharge, shelf depreciation and high temperature, SF
6Gas can decompose, and its analyte can become the corrosivity electrolyte after running into moisture, and some high toxicity analyte wherein is as SF

2, their Diazolidinyl Ureas, eyes, mucous membrane if suck excessively, also can cause dizziness and pulmonary edema, even the causing death.Be filled with SF
6The equipment of gas is installed in indoor mostly, and circulation of air speed is relatively slow, if SF
6Gas will be in case leakage will be difficult for distributing SF in indoor deposition
6Gas itself is again colorless and odorless, leaks the back and is difficult for being realized.In addition because SF
6The proportion of gas is bigger than air, is deposited on low sheaf space often, causes local anoxic easily, and the people is suffocated.
China's " electrical safe working order " special provision must be installed oxygen and SF in relevant place
6The detection alarm device, and necessary compound ventilation air-changing device is installed.The infrared imagery technique detection method: act on easy leakage point by infrared radiation, utilize infrared imagery technique to observe the gas leakage disturbance on display, judge to have or not to leak to produce, this method advantage is a non-contact detecting at a distance.
The utility model content
The technical problems to be solved in the utility model is: a kind of sulfur hexafluoride gas leak supervision warning device is provided, can leaks by accurate, safe and reliable monitoring sulfur hexafluoride gas.
