Research on Detection of Gas Components in Insulation Fault Characteristics of Air Switch Cabinet

In this paper, the fault discrimination method of GIS equipment is studied, and a method for detecting the gas composition of the insulation fault characteristic in the air switch cabinet is proposed. First, analyze the decomposition mechanism of partial discharge air in the air under the condition of insulation fault, determine the characteristic gas of insulation fault as the detection object, and analyze the influencing factors that affect the characteristics of the characteristic gas. Then establish a simulation model for the air switch cabinet, analyze the flow characteristics of the indoor gas, and establish the installation position of the characteristic gas detection sensor on this basis.
