摘要

户内变电站中电气设备安全稳定运行受运行环境温度影响，针对“机械排风+百叶窗进风”通风散热方式中百叶窗进风口开展优化，旨在改善气流组织分布，提高通风散热效果和设备运行效率。首先，以电容器室为研究对象，建立电容器室相关设备及室内环境的仿真模型，使用网格收敛指数（GCI）验证网格模型独立性，通过实测与仿真数据拟合验证仿真结果准确性。然后，通过控制变量法对电容器室的百叶窗宽高比（0.4、0.8、1.6）和百叶倾斜角度（±60°、±45°、±30°、±0°）进行方案配置和数值模拟。最后，以电气设备运行区域内温度最低为目标，对百叶窗进风口设计参数进行优化分析。研究结果表明，最佳方案为百叶窗宽高比0.8且百叶倾斜角度-45°的配置方案，电气设备运行区域内平均温度为34.9℃，平均流速为0.47 m/s，与原方案相比平均温度降低23.8%，平均流速提高5.4倍。百叶窗宽高比和百叶倾斜角度与电气设备外型尺寸匹配使气流组织分布得到改善，经过优化后能够有效降低电容器室内温度，同时为户内变电站通风散热系统优化设计提供了参考。

Abstract

The safe and stable operation of electrical equipment in indoor substation is affected by the operating environment temperature. Optimization is carried out on the louver air inlet in the“ mechanical exhaust+louver air intake”ventilation and the heat dissipation mode

aiming to improve the airflow organization distribution

enhance ventilation and heat dissipation efficiency

as well as equipment operational efficiency. First

with the capacitor compartment as the research object

the simulation model of the related equipment of the capacitor compartment and the indoor environment is set up

the grid convergence index (GCI) is used to verify the independence of the grid model

and the accuracy of the simulation results is verified by fitting the measured and simulation data.Then

the scheme configuration and numerical simulation of the louvers aspect ratio (0.4

0.8

1.6) and the louvers tilt angle (±60°

±45°

±30°

±0°) of the capacitor compartment are performed by the control variable method.Finally

with the lowest temperature in the operating area of electrical equipment as the target

the louvers intake design parameters is optimized and analyzed. The research results show that the best scheme is the configuration scheme of louvers width ratio 0.8 and louvers tilt angle-45°. The average temperature in the operating area of electrical equip ment is 34.9℃

the average flow rate is 0.47 m/s

and the average temperature decreases by 23.8% and the average flow rate increases by 5.4 times compared to the original scheme.The airflow distribution is improved by matching the louwer aspect ratio and tilt angle with the external dimensions of the electrical equipment. The optimization effectively reduces the temperature inside the capacitor compartment and provides a reference for the optimized design of ventilation and heat dissipation system for indoor substation.
