三峡直流换流站等值附盐密度取值的研究

Study of Equivalent Salt Deposit Density for Three Gorges DC Converter Station

针对宜昌市大气污染和三峡换流站站址附近污秽状况，结合三峡换流站附近交、直流设备盐密测量和运行经验以及宜昌气候特征，提出了三峡换流站适用的等值附盐密度值，并在此基础上提出了交、直流户外设备外绝缘的有关结构参数。

Based on the detailed investigation about the present conditions of polution in Yichang and Three Gorges DC converter stations and its prediction,and concerning the ESDD measurement of DC,AC equipment near the Three Gorges DC converter station,the operating experience and the atmospheric characters of the Yichang city,the porper data of ESDD of Three Gorges DC converter station is presented.And further more,presents the related structural parameters of outer insulation of out door DC,AC equiptment.
