This has led to a persistent increase in the power consumption and operating temperatures of internal components, thereby exacerbating the issue of electrical equipment overheating. The research and development of thermal management technologies hold a significant position in the design and manufacturing processes of electrical equipment, as they directly impact the thermal management efficiency during normal operation, which in turn affects the product’s reliability and expected lifespan. Prior to the production phase of a product, it is imperative to utilize thermal analysis software for optimizing the product’s thermal performance and structural design. This study focuses on dynamic reactive power compensators, employing Solidworks software to conduct thermal simulation analysis on the electrical cabinets of dynamic reactive power compensators. The research primarily encompasses the following aspects: during the model construction phase, the model is simplified as necessary to meet the parameter requirements for thermal simulation and to establish the model diagram of the reactive power compensator. In the thermal simulation phase, the software’s modules are utilized to perform fluid analysis on the electrical cabinet. By setting the flow boundary conditions and initial temperature conditions, the internal flow field and temperature distribution within the electrical cabinet are simulated, generating a temperature distribution cloud map. In response to the thermal requirements of dynamic reactive power compensators, this study designs a wind cooling solution. By comparing the internal flow field and temperature distribution cloud maps under conditions with and without fans, the impact of fans on thermal performance is assessed. The simulation results indicate that with the installation of fans, the internal temperature of the electrical cabinet is significantly reduced, which contributes to enhancing the long-term operational safety and stability of the equipment.展开更多
