摘　　要：三峡至广东 50 0ｋＶ直流输电线路的设备外绝缘水平是工程建设的基本问题之一 ,因此对广东侧直流换流站站址所在区域的污秽状况进行了调查。通过分析该换流站站址区域的主要废气排放量、大气环境质量、气象状况和主要污染源的情况 ,确定了该换流站的交、直流污秽等级 。The equipment external insulation level of 500 kV DC transmission line from the Three Gorges to Guangdong is a basic consideration in the project, and an investigation was made into the pollution condition on the location for its Guangdong-side converter station. By analyzing the exhaust emissions, atmospheric and environmental quality, weather and major pollutant sources on the location, the AC/DC pollution grade of the converter station is determined along with corresponding specific creepage distance and equivalent salt deposit density (ESDD).
