| 摘 要： | 在2种盐密、4种海拔高度（气压）下对3种不同伞形结构的750kV电站支持绝缘子进行了人工污秽试验，得出不同支持绝缘子污闪电压随海拔高度（气压）的变化规律。对于不同结构绝缘子，分别给出750kV变电站所需的最低绝缘高度。并对伞裙结构进行了选择。

| Abstract: | Artificial contamination tests were carried out for three types of porcelain post insulators in four air pressure cases corresponding to the altitude from 0m to 3000m and in two typical kinds of equivalent salt deposit density (ESDD). The test results indicate the regularity of the flashover voltage of polluted post insulators at different altitudes. The heights of post insulators, which match the 750kV transformer substation, were put forward accordingly. |
