架空绝缘配电线路复合材料防雷应用介绍

Overhead Insulation Distribution Line Composite Material Lightning Protection Application Introduction

文章介绍10kV架空绝缘线路断线的主要原因,指出其危害;提出可以使用复合材料制作而成的绝缘横担代替原有的铁横担及绝缘子,提高线路的绝缘性能,减小线路因遭受雷击而发生断线的概率;并给出了复合绝缘横担的相关种类以及应用于电杆上各种相应的杆头布置方式。另外,文中还阐述了复合绝缘横担能够提高架空绝缘线路防雷性能的机理。

Introduce the main reason of 10 kV overhead insulation line breakage,and point out the harms.It is proposed that an insulation cross arm made of composite material can be used instead of the original iron cross arm and insulator to improve the insulation performance of the line and reduce the lightning strike on the line.The probability of disconnection is given.The related types of composite insulated crossarms and various corresponding head configurations for poles are presented.The mechanism of the composite insulated cross arm for improving the lightning protection performance of overhead insulated lines is described
