雷击500 kV输电线路杆塔分流特性计算研究

Dianci bileiqi
雷击对输电线路安全运行和设备可靠性造成了严重威胁。目前针对真实环境和运行条件下500 kV输电线路杆塔雷电流分流特性研究还不够全面。本研究利用ATP-EMTP进行雷击500 kV输电线路仿真计算，研究多种工况下被雷击杆塔的分流系数。研究结果表明，雷电流波头时间从1.2 μs增大至20 μs，杆塔分流系数降低40%；半波时间从20 μs增大至350 μs，杆塔分流系数降低0.8%；雷电流幅值对分流系数无影响；杆塔接地电阻从1 Ω增大至30 Ω，杆塔分流系数降低19.7 ...

雷电A分量作用下碳纤维复合材料的损伤发展机制及防护研究

Dianci bileiqi
为研究雷电作用环境对碳纤维复合材料损伤特性的影响规律，搭建雷电流A分量作用下含紧固件碳纤维复合材料的试验平台及仿真模型，得到了单次雷电流A分量及3次雷击下碳纤维复合材料的损伤发展机制，并对单次雷电A分量作用下铜网防护后试样的防护效果进行研究。研究结果发现，单次雷击下试样的损伤以内部分层损伤为主，单次雷击后紧固件与孔区域间隙变大，接触阻抗增大，导致后续多次雷电作用下试样的电流传导路径发生变化，表面电流分流值增加，在雷电通道和电流分流的共同作用下试样表面损伤加重，内部分层损伤发展变化减缓 ...
