摘　　要：当空气湿度较大时,变电站室外端子箱(甚至是开关、刀闸机构箱等)表面和内部有凝露产生。凝露对室外端子箱内部的电气设备有严重危害,为了防止凝露产生,室外端子箱安装了加热器。现在变电站对室外端子箱加热器的控制比较落后,有的加热器形同虚设。针对这一实际情况,本文主要把变电站室外端子箱温湿度控制方式智能化。When the air humidity is big, the substation outdoor terminal box （orswitches, the mechanism box etc.） surface and internal condensation produced.Electrical equipment gel on internal ou（door terminal box has serious harm, in order to prevent the occurrence of condensation, outdoor terminal box installedheater. Now the outdoor terminal box heater control substation is relatively backward, some heater useless. In the light of this situation, this paper mainly to the intelligent substation outdoor terminal box temperature and humidity controlmode.
