Abstract

Due to the large internal volume of the switch cabinet, when the characteristic gas is generated due to partial discharge and other faults, it will show different distribution in each position of the switch cabinet. In this paper, by building a real switch cabinet model, the characteristic gas diffusion process of a specific gas generation position is simulated. By setting the gas product ratio and boundary conditions, the dynamic diffusion process of NO₂ and O₃ in the switch cabinet at different times is analyzed, and the phenomenon is explained and analyzed. Through the summary of the diffusion law, combined with the switch cabinet structure and gas distribution, the optimal detection position of the gas sensor is obtained, which provides theoretical and data support for the experiment.
