Description

technical field [0001] The invention provides an acid substance absorption device in sulfur hexafluoride gas, which belongs to the technical field of power system detection technical background [0002] In electrical equipment, sulfur hexafluoride gas will decompose under high-voltage discharge conditions to produce various impurities, which react with trace moisture in sulfur hexafluoride gas to produce acid or acidic substances. The acidic substances in sulfur hexafluoride gas will corrode the metal parts and insulating materials of electrical equipment, directly affect the mechanical, electrical and insulating properties of the equipment, and in severe cases will affect the safe operation of electrical equipment, so it is necessary to treat sulfur hexafluoride Acidic substances in the gas are detected by absorption. The Chinese patent with the patent number "CN2015202422065" discloses an absorption device for acidic substances and hydrolyzable fluoride in sulfur hexafluo...

AI Technical Summary

Problems solved by technology

The utility model has the characteristics of convenient operation, high absorption efficiency, and less solution consumption. The disadvantages are: 1. There is no real-time detection function of the absorption process, so it is difficult to ensure the complete absorption of acidic substances in sulfur hexafluoride gas and accurate detection of the measured six The volume of sulfur fluoride gas; 2) only rely on sulfur hexafluoride gas to enter from the bottom of the gas absorption pool and absorb it by NaOH solution, the absorption efficiency needs to be further improved and increased
