Description

Intelligence SF6 linear degree analysis appearance
Technical Field
The invention relates to the technical field of gas analysis, in particular to an intelligent SF6 linearity analyzer.
Background
Sulfur hexafluoride gas is an artificial inert gas synthesized by two french chemists in 1900, and was used by the U.S. military around 1940 in the manhattan project (nuclear military). Was provided commercially in 1947. Pure SF6 gas is generally recognized as non-toxic. SF6 has a small amount of accompanying products in the production process, wherein S2F10 is a recognized highly toxic gas, but can be completely removed through purification treatment. Although the pure SF6 gas is non-toxic, the concentration of SF6 gas is prevented from rising to oxygen deficient levels in the field. The density of SF6 gas is about five times that of air, and SF6 gas, if leaked, will tend to deposit in depressions such as cable trenches. Excessive concentrations present a choking hazard and are considered in the design of indoor ventilation units. SF6 gas can be mixed with air by convection, but at a slow rate. Once mixed, the gases form a mixed gas of SF6 and air, which does not separate again. The problem is serious in that the decomposition products of SF6 under the action of electric arc such as SF4, S2F2, SF2, SOF2, SO2F2, SOF4 and HF, etc., are strongly corrosive and toxic.
In the prior art, the gas analyzer has a single function, the device cannot be subjected to leak detection before use, the inside of the analysis device does not contain other impurity gases when the gas to be detected is analyzed, the accuracy of an analysis result can be influenced to a certain extent, standard gases are not compared when the gas is analyzed, the analysis result is unreliable, partial results of the gas analysis can be roughly known only through the gas analysis device, the difference between each index after the gas analysis and the standard gases cannot be known in detail, the improvement processing and the like of relevant aspects of the gas to be detected cannot be realized according to the analysis result, and after the analysis, the gas cannot be recycled or subjected to pollution-free processing, and the environment is polluted to a certain extent.
