Description

一种防雷双悬式复合绝缘子串
技术领域
本实用新型用于输电线路领域，特别是涉及一种防雷双悬式复合绝缘子串。
背景技术
随着工业发展，用户对电能的需求越来越高，输电线路的容量正向更大的方向发展，线路的容量增大，则导线的截面增加，同时导向重量增加，目前在输变电线路中，塔与线路之间主要依靠各类连接金具进行连接，因此对导线与杆塔之间连接的金具要求也越来越高，金具的机械强度要求必须加大，而大强度的金具不但制作成本高，且体积庞大、结构复杂，造成线路投资高，也给线路安装和维修带来不便。
此外，输电线路及电气设备在雷雨季经常遭受雷击，雷害严重地区，容易造成大面积线路跳闸、线路断线等事故的发生，影响正常供电，形成很大的经济损失。
实用新型内容
为解决上述问题，本实用新型提供一种结构简单、安装方便、机械强度高，防雷效果好的防雷双悬式复合绝缘子串。
本实用新型解决其技术问题所采用的技术方案是：一种防雷双悬式复合绝缘子串，包括上联板、下联板以及连接所述上联板和下联板的两条并行设置的绝缘子串，所述上联板上设有与输电塔连接的金具，与所述下联板连接设有若干悬垂线夹，所述上联板和下联板上在所述绝缘子串的一侧设有正对伸出的避雷器。
进一步作为本实用新型技术方案的改进，两所述绝缘子串的上端均通过球头挂板与上联板连接，两所述绝缘子串的下端均通过碗头挂板与下联板连接，所述球头挂板和碗头挂板上均装有电弧环。
进一步作为本实用新型技术方案的改进，所述下联板通过挂板连接底联板，各所述悬垂线夹均悬挂在所述底联板上。
进一步作为本实用新型技术方案的改进，所述金具包括两个倒扣在一起的U型挂环，所述U型挂环的上端连接铰接座，下端连接上联板。
进一步作为本实用新型技术方案的改进，所述绝缘子串采用复合绝缘子串。
进一步作为本实用新型技术方案的改进，各所述悬垂线夹内均装有护线套。
本实用新型的有益效果：本防雷双悬式复合绝缘子串在上联板和下联板间设置两并行的绝缘子串，上联板通过金具连接输电塔，下联板通过悬垂线夹承担输电导线，如此本实用新型通过上述结构的改进增加了连接导线的机械强度的同时，保证了整体结构的简便性，降低制作成本，节约线路投资，也方便线路安装和维修。同时，在上联板和下联板上设置避雷器，避免雷击后造成大面积线路跳闸、线路断线等事故的发生，保证正常供电，降低经济损失。
