绝缘横担类措施对10kV变电站雷电侵入波的影响

Dianci bileiqi, 2017
绝缘横担类措施会增加10kV变电站雷电侵入波造成的风险。采用ATP-EMTP建立了10kV变电站直击与反击雷电侵入波计算模型,推导了变电站内主设备平均故障间隔时间（Mean Time Between Failure,MTBF）的计算方法。计算并分析了进线段杆塔接地电阻、雷电流波头和幅值概率分布、改善措施对主变、站用避雷器MTBF的影响。结果表明:采用绝缘塔头或绝缘横担后,变电站主变雷电侵入波MTBF大幅降低;进线段杆塔接地电阻、雷电流波头和幅值概率分布对10kV变电站雷电侵入波MTBF影响很大 ...
