摘要
对海上换流站户内直流场进行了上送下回,下送上回及目标送风三种形式的气流组织的数值计算,分析了对应直流场空间的流场与温度场特性,以设备表面平均温度为指标比较气流组织对发热设备的冷却效果,结果表明:目标送风方式的气流组织能更加有效地实现对桥臂电抗器的冷却。
Numerical software is employed to simulate the air flow and temperature fields in the indoor DC field of an offshore converter station under three kinds of air distribution, i.e., up-supply and down-return, down-supply and up-return and, targeted air supply. The characteristics of the corresponding flow and temperature fields are analyzed.Cooling effectiveness of the three kinds of air distribution are assessed and compared according to the corresponding average temperatures of the heat emitting equipment surface. Results reveal that the targeted air supply system cools the bridge arm reactor the best.
