为合理控制居民区地下配电房的室内温度,降低机械通风带来的环境噪声,建立了配电房风速场仿真模型并对其进行分析计算。以某住宅楼地下配电房为例,使用ANSYS13.0软件对其中主要热源——变压器周围的风速场进行模拟与分析。结果表明:在保证室内电气设备工作温度前提下,优化计算通风量,通过电缆沟辅助进行机械排风,使配电房噪声由之前的平均值79 dB降低到71 dB。通过修改模型参数,可用于其它地下配电房温度场的模拟与预测,为前期设计提供参考。
為閤理控製居民區地下配電房的室內溫度,降低機械通風帶來的環境譟聲,建立瞭配電房風速場倣真模型併對其進行分析計算。以某住宅樓地下配電房為例,使用ANSYS13.0軟件對其中主要熱源——變壓器週圍的風速場進行模擬與分析。結果錶明:在保證室內電氣設備工作溫度前提下,優化計算通風量,通過電纜溝輔助進行機械排風,使配電房譟聲由之前的平均值79 dB降低到71 dB。通過脩改模型參數,可用于其它地下配電房溫度場的模擬與預測,為前期設計提供參攷。

In order to control the temperature of residential underground distributing substations reasonably and to reduce environmental noise caused by mechanical ventilation, this paper built up and calculated the simulation model of wind ifeld in distributing substation. Tak-ing certain dwelling house for example, this paper simulated and analyzed the main heat source from the wind ifeld around the main trans-former with the software, ANSYS13.0. The simulation results show that under the normal temperature of electrical equipment in the room, the ventilation volume was optimized by machinery exhaustion assisted by cable trench, and the noise level decreased from 79 dB to 71dB. If the model parameters were modiifed, the model could be used to predict the temperature ifeld in the same kind of substations, so as to put forward an optimum proposal for noise treatment, and provide more references for preliminary design.
