Absorbing device for measuring mineral oil content during sulfur hexafluoride gas analysis

Abstract

The invention discloses an absorbing device for measuring mineral oil content during sulfur hexafluoride gas analysis. The absorbing device for measuring the mineral oil content during the sulfur hexafluoride gas analysis is characterized by comprising a temperature control system for precisely controlling the temperature of a mineral oil absorbing device and having an adjustable temperature function, two communicated gas washing bottles connected with the temperature control system and used for accommodating absorbing liquid, a gas flow control system communicated with the gas washing bottles and used for precisely setting and regulating the gas flow rate and displaying the total amount of flowing gas, and a connecting sleeve for communicating a gas circuit. The absorbing device for measuring the mineral oil content during the sulfur hexafluoride gas analysis is high in degree of automation, improves sampling accuracy and sample representativeness through stable control and improves the accuracy of a sulfur hexafluoride gas purity analysis result.

Description

technical field [0001] The invention relates to the technical field of sulfur hexafluoride gas analysis, in particular to an absorption device for measuring mineral oil content in sulfur hexafluoride gas analysis. Background technique [0002] Compared with air and transformer oil, sulfur hexafluoride gas has many excellent electrical insulation and arc extinguishing properties. In recent years, the application of sulfur hexafluoride gas in electrical equipment has developed greatly, especially in high-voltage And ultra-high voltage circuit breakers, there are also fully enclosed combined electrical appliances. The electrical industry uses its high dielectric strength and good arc extinguishing performance to use it as an insulating material for high-voltage switches, large-capacity transformers, high-voltage cables and gases. Six The purity of sulfur fluoride gas directly affects the safety of the power system. At present, a large number of sulfur hexafluoride gas monitorin...

Problems solved by technology

[0005] Due to the low volatilization temperature of the mineral oil absorption liquid, in the prior art, the ice-water mixture is generally used to adjust the absorption temperature, but because the adjustment temperature of the ice-water mixture can only be controlled at 0 degrees, the temperature control ability is limited, when the existing technology When the absorption temperature of the mineral oil absorption device is too high, the absorption liquid is easy to lose, which affects the absorption effect of mineral oil, and the accuracy of the test results is reduced. The minimum detection amount is large, and the analysis error introduced to the accurate test analysis results is relatively large
