Abstract

The present application relates to a mixed gas humidity detection method, system, device and computer equipment, wherein, a mixed gas humidity detection method is obtained by obtaining the gas mixture ratio of the gas to be measured and detecting the total gas pressure of the gas to be measured, and based on the gas The cooling threshold is determined by the mixing ratio and the total gas pressure, and the mirror temperature of the chilled mirror is adjusted according to the cooling threshold, so as to prevent the mirror temperature of the chilled mirror from being lower than the liquefaction temperature of the preset type of gas in the gas to be measured, and prevent the preset type of gas from being on the chilled mirror. The result is a dew layer, thereby ensuring that when the thickness of the mirror frost layer is detected, the detected data can accurately reflect the actual thickness of the mirror frost layer, which improves the detection accuracy and avoids measurement failure.

Description

technical field [0001] The present application relates to the technical field of gas measurement, and in particular, to a mixed gas humidity detection method, system, device and computer equipment. Background technique [0002] With the advancement of the environmental protection industry, in order to reduce the impact of sulfur hexafluoride on the environment, finding new environmentally friendly gases to replace the role of sulfur hexafluoride in various gas-insulated equipment has become a research hotspot in the power industry. At present, the environmentally friendly gas C 4 F 7 The GWP (Global Warming Potential) of N (heptafluoroisobutyronitrile) is significantly lower than that of SF 6 (Sulfur Hexafluoride), subject to higher liquefaction temperatures, requires 2 (carbon dioxide) mixed use, C 4 F 7 N / CO 2 Mixed gas is expected to replace SF 6 Used in all kinds of gas-insulated equipment. C 4 F 7 N / CO 2 The humidity of the mixed gas has a significant impact ...
