摘　　要：旨在探讨L形导风管尺寸变化对配电站系统性能的影响。通过理论分析与实验研究,评估了不同尺寸的L形导风管对系统气流分布、散热效果和压力损失的影响。实验结果显示,随着导风管尺寸的增大,平均气流速度减小,温度分布更加均匀,但系统压力损失显著增加。本研究为L形导风管的设计提供了理论依据和技术支持,有助于提高配电站系统的散热性能和运行效率。This paper aims to explore the impact of changes in the size of L-shaped air ducts on the performance of distribution station systems.Through theoretical analysis and experimental research,the influence of different sizes of L-shaped air ducts on the airflow distribution,heat dissipation effect,and pressure loss of the system was evaluated.The experimental results show that as the size of the air duct increases,the average airflow velocity decreases and the temperature distribution becomes more uniform,but the system pressure loss significantly increases.This study provides theoretical basis and technical support for the design of L-shaped air ducts,which helps to improve the heat dissipation performance and operational efficiency of distribution station systems.
