| 摘 要： | 结合线路运行中绝缘子雷击故障的特点,对绝缘子悬挂方式、均压环的形状及均压环的布置方式进行了耐雷电冲击特性试验,试验研究结果表明并联绝缘子串的雷击击穿电压较单串时低;开口状均压环的均压效果和引弧效果均优于闭口状均压环;均压环的开口方向与导线垂直时,可保护绝缘子和导线。

| Abstract: | Combined with the features of lightning faults of insulators in the operation of transmission lines,the effects of insulator suspension mode as well as the shape and installation mode of grading ring on lightning impulse characteristic are investigated in this paper.It is concluded that the flashover voltage of parallel insulator string is lower than that of single insulator string;the effects of grading and guiding arc of the open-shape grading ring are better than those of the closed-shape grading ring;when the opening direction of grading ring is perpendicular to the conductor,it helps to protect the insulator and the conductor. |
