线路避雷器安装布点策略研究
|
摘要
雷击是引起输电线路跳闸的主要原因之一。加装线路避雷器是根治输电线路雷击跳闸的有效手段。以福建电网220kV卓旧I路为例,建立了反击计算模型,对比了不同避雷器安装方式对典型杆塔及其相邻杆塔反击耐雷水平和反击跳闸率的影响,得到了线路避雷器的保护作用范围,并据此提出了避雷器安装布点策略:优先考虑连续多基杆塔反击跳闸率为C级或D级的情况,结合线路档距制定不同的安装方案;对于杆塔反击跳闸率为C级和D级,相邻杆塔未达到C级或D级的情况,C级杆塔安装一相避雷器,D级杆塔安装两相避雷器。基于提出的避雷器安装布点策略,以220kV卓旧I路为例,在防雷改造时可减少线路避雷器安装数量,提高线路运行经济性。
Lightning strike is one of the main reasons causing the tripping of the transmission lines. The installation of line arresters is an effective means to solve lightning strikes on transmission lines. Taking the 220kV Zhuojiu I Road of Fujian Power Grid as an example,a counterattack calculation model is established,counterattack lightning protection performance of the typical tower and its adjacent tower of a220kV transmission line with different line arrester configurations is analyzed and compared,the protection range of the line arrester is obtained and the installation strategy of line arrester is put forward: Priority is given to the case where the continuous multi-base tower counter-attack trip rate is C-class or Dclass,and different installation schemes are established in combination with the line span; for the tower counter-attack trip rate is C-class and D-class,the adjacent tower does not reach C-class or D-class In the case,the C-class tower is equipped with a phase arrester,and the D-class tower is equipped with a two-phase arrester. Based on the proposed installation strategy of the arrester,taking 220kV Zhuoji I as an example,the number of lightning arresters installed can be reduced during lightning protection and the line operation economy can be improved.
