摘要:

变电站二次设备运行时对环境温度有一定要求,最佳运行温度在20.0~25.0℃。介绍了二次设备预制舱内散热器件的传统方案,指出其不足,提出了毛细管式散热风道,并将此毛细管风道方案应用于空调与风机联动的散热模式,该方案热平衡好,系统可靠性高,节能效果显著。

Abstract:

Substation secondary device requires environmental temperature. The ideal operation temperature is 20.0℃ to 25.0℃. Traditional radiating solution for secondary precast bin was introduced. And the drawback was indicated. This paper introduced a composite radiating solution that combined air conditioner and fan. This solution featured with well heat balance, high reliability, and remarkable energysaving effect.
