摘　　要：地下二层结构变配电站因环境控制问题导致的开关柜故障主要是由凝露引起的。本文在对开关柜运行故障现象分析的基础上,通过对凝露机理的分析,找出变电站内引发开关柜凝露成因,提出防止开关柜凝露的主要措施。应用可控弱气流通风设计技术,结合智能环境控制系统,构建二层结构变配电站开关室的环境控制工程方案。工程应用后的运行结果表明,该系统可以有效地控制变配电站开关室内的温度和湿度,防止潮湿凝露的产生。与常规的环境控制技术相比,运行能耗显著下降,室内空气品质得到有效控制,维护工作量显著降低,变配电站的运行环境得到有效改善,环境控制的智能化水平得到提高。The failure of the switchgear due to environmental control problems in the underground two-story structural substation is mainly caused by condensation.Based on the analysis of the failure phenomenon of the switchgear,this paper analyzes the condensation mechanism to find out the cause of the condensation of the switchgear in the substation,and proposes the main measures to prevent the condensation of the switchgear.Using the controllable weak airflow ventilation design technology,combined with the intelligent environmental control system,the environmental control engineering scheme of the switch room of the two-story structural transformer substation is constructed.The operation result after the engineering application shows that the system can effectively control the change/substation switch.The indoor temperature and humidity prevent the generation of moist condensation.Compared with the conventional environmental control technology,the operating energy consumption is significantly reduced,the indoor air quality is effectively controlled,the maintenance workload is significantly reduced,and the operating environment of the transformer&substation is obtained.Effective improvement,the level of intelligence in environmental control has been improved.
