Numerical Simulation and Optimization on Ventilation and Heat Exchange in Indoor Substation
摘要
Abstract
In order to find a solution to the improper work for electric equipment in indoor substation due to high temperature caused by the inadequate ventilation and heat transfer in summer,the numerical simulation has been conducted on the perform-ance of ventilation and heat exchange in main transformer room using Fluent software.The distribution for velocity and temperature in the room has also been considered,while the position and the size for both inlets and outlets in substation has also optimized to an optimum level.As a result,the method enhancing the performance of heat exchange has been put forward by installing guide vanes under the inlets and numerical calculation has also conducted on the configuration of guide vanes to an optimum level,which can provide a good reference for the later design of indoor substation,ensure the safe operation of electric equipment at high tem-perature in summer,and reduce the effects of noise caused by the substation on the urban environment.关键词
