110kV“上”字型输电线路复合材料横担耐雷水平研究

Study on Lightning Withstand Level of Composite Cross Arm Tower in 110kV Transmission Line with Glyph Tower

随着材料工艺和技术的不断成熟,复合材料在输电线路杆塔工程中应用逐渐增多,为研究复合材料杆塔在110kV输电线路中的防雷性能,在ATP-EMTP软件中建立110 k V典型"上"字型输电线路复合材料横担仿真模型,从地面倾角和复合横担不同长度等对杆塔耐雷水平进行研究。根据耐雷水平计算结果,提出同时满足防雷性能和安全裕度优化的复合材料杆塔结构方案。

With the continuous maturity of material technology,composite materials are gradually increasing in the application of transmission line tower engineering. In order to study the lightning protection performance of composite cross arm tower in 110 k V transmission line,the simulation model of composite tower of 110 k V typical transmission line with glyph tower is established in ATP-EMTP software. The lightning withstand level of composite tower is studied from the ground elevation and the different length of cross arm. According to the calculation results of lightning withstand level,the structure scheme of composite tower which can satisfy the optimization of lightning protection performance and safety margin at the same time is put forward.
