Research on CFD Simulation Technology of Wet Air Flow and Heat Transfer in Switchgear

Substations are crucial in power supply and economic development, but the high humidity environment in the southwest region can easily lead to equipment moisture and insulation degradation, posing a threat to their safe operation. Intelligent substations require higher environmental conditions, and achieving low-carbon, safe, and intelligent regulation has become a key challenge. This article combines CFD simulation and experimental testing to study the intelligent control technology of substation environment, proposes humidity control technology standards, and provides theoretical basis and practical guidance for the reliable operation of substations in high humidity areas of Southwest China.
