| 摘 要： | 文章主要根据高海拔地区线路经过的污秽等级,通过泄漏比距计算出了工频电压条件下所要求的绝缘子片数,并进行海拔修正,然后根据操作过电压及雷电过电压对该绝缘子片数进行复核,最终确定导线绝缘子片数.

| Abstract: | The pieces of insulator under power frequency voltage are calculated and corrected through leakage distance ratio based on pollution class of transmission line at high altitude area,then the pieces are checked under the conditions of operating over-voltage and lightning over-voltage,finally the pieces of insulator are determined by comparisons of the pieces under power frequency voltage,operating over-voltage and lightning over-voltage. |
