The ESDD correction was made taking consideration of CaSO4 content in site pollutant which considerably effects on pollution withstand voltage and disposition of polluted external insulation for 1 000 kV substation post and hollow insulators was given,e.
对于1000kV变电站支柱和空心绝缘子进行污秽外绝缘设计,考虑到现场污秽中所含CaSO4对污耐受电压影响较大,进行了等值附盐密度校正,最后给出了1000kV变电站支柱和空心绝缘子的污秽外绝缘配置,建议Ⅲ级污秽等级1000kV瓷空心绝缘子的结构高度为11。
It is suggested that proper winding angle should be choiced depending on application of composite hollow insulator to enhance its performance price ratio.
复合空心绝缘子的机械性能,主要决定于其内部的环氧玻璃纤维缠绕管(以下简称缠绕管)。
