Preparation device and method of HF standard gas in SF6 (sulfur hexafluoride) gas

Abstract

The invention discloses a preparation device and method of HF standard gas in SF6 gas. The preparation device comprises a thermostatic water bath device comprising a first waterbath and a second waterbath communicated with each other, wherein a heating module and a temperature-detecting module are arranged in the first waterbath; the top of the second waterbath is sealed and a sealed inner groove for containing hydrofluoric acid liquid is arranged in the second waterbath; the front end and the back end of the inner groove are respectively connected with an air inlet pipeline and an air outlet pipeline both penetrating through the second waterbath; the outlet of the air outlet pipeline is connected with an SF6 air acidity-measuring device. The device solves the standard magnitude-transmitting problem when the SF6 air acidity-measuring device is used for measuring acidity, can directly calibrate the SF6 air acidity-measuring device to enable the SF6 air acidity-measuring device to be more accurate in measured data, has the characteristics of being short in time consumption, good in effect, convenient to use and the like, and provides a powerful safeguard for the safe operation of electrical equipment.

Description

technical field [0001] The present invention relates to a kind of SF 6 The device and method for preparing HF standard gas in gas belong to the technical field of power system application. Background technique [0002] Sulfur hexafluoride gas has excellent insulation and arc extinguishing properties, and is widely used in various high-voltage and ultra-high-voltage electrical equipment. In order to ensure the safe operation of electrical equipment, it is necessary to control the content of various impurity components in sulfur hexafluoride gas, especially the acid and acidic components that are severely corrosive to the solid insulation materials of electrical equipment must be strictly controlled, the most important of which is One of the most corrosive acids is HF. Therefore, sulfur hexafluoride gas needs to be tested for acidity before use, but at present, SF 6 The standard measurement method of gas acidity cannot be directly calibrated, resulting in the inability to j...

AI Technical Summary

Problems solved by technology

Therefore, sulfur hexafluoride gas needs to be tested for acidity before use, but at present, SF 6 The standard measurement method of gas acidity cannot be directly calibrated, resulting in the inability to judge the accuracy of the detection data, which brings hidden dangers to the safe construction and production of the power grid, and needs to be improved urgently
