| 摘 要： | 安装高度对瓷套式氧化锌避雷器的电位分布有重要的影响。首先针对一500kV瓷外套式氧化锌避雷器,建立其有限元计算模型,分析了其最大持续运行电压条件下的电位分布,同时采用光纤-电流法完成了相关的实验,验证了计算方法的有效性。然后分析了安装高度对500kV、220kV、110kV瓷套式氧化锌避雷器电位分布的影响。发现:改变安装高度对110kV、220kV避雷器的电压分布影响较小,但是增大安装高度可使500kV上节和下节避雷器的电压分布系数趋于理想。

| Abstract: | Mounting height is one of important factors effecting the potential distribution of porcelain ZnO arrester. Firstly,to one 500 kV porcelain ZnO arrester,the calculation model is developed to analyze the potential distribution under its maximum continuous operating voltage. Then relevant experiment is performed to verify the validity of the calculation method using optical fiber-current measurement method. Finally,the influence of mounting height on arresters with different rated voltages of 500kV,220kV and ... |
