摘要
介绍了线路氧化锌避雷器在宜昌所辖500 kV线路上的应用,针对雷害较为严重的三江二回线路59#杆塔,采用了ATP-EMTP软件建立了仿真模型,并对该基杆塔安装线路避雷器前后的耐雷水平进行计算.结合线路避雷器挂网运行的实际情况,认为避雷器的应用是输电线路有效的防雷措施.
This paper introduces the application of zinc oxide arresters on 500 kV lines governed by Yichang. Considering the severely disturbed lightning 59# tower on the second 500 kV single-circuit transmission line of San-Jiang, a simulation model is built using ATP-EMTP software to calculate the lightning withstand level before and after the installation of line arrester. The practical use of line arrester in operation shows that using arrester is an effective method to protect lightning.
