Dianci bileiqi, 2018 为了有效对分布式基站远端射频单元（RRU）直流电源进行雷电浪涌防护,需要对具体保护方式及效果进行研究。本文介绍了几种常见的塔放式RRU直流电源SPD防护模式,利用EM-TP软件搭建仿真模型,分析雷击通信铁塔时不同保护模式的防护效果,讨论铁塔高度和雷电流波形对RRU电源线泄散雷电流幅值的影响,最后计算不同雷电流波形下电缆与SPD承受能量占全部能量的比值。仿真结果表明:在-48 V、RTN线与铁塔三线间均安装SPD时防护效果最好,流经直流电缆的电流幅值最低,波形持续时间也最短。铁塔高度越低 ...

Dianci bileiqi, 1993 据美国《IEEE Trans.Elec.Insul.》杂志报道。对在SF6气体中表面电荷对绝缘子冲击闪络的影响进行了研究。由电晕放电电源使绝缘子表面产生线性分布或均匀分布的多极性电荷,或者具有相邻电极（同号电荷）或相反电极（混合电荷）的双极电荷。拥有分裂电极的试验装置借助电容式探测器可以测定整个绝缘子的表面。研究得出了如下结论:使阴极电场增大的表面电荷分布对在SF6气体中的绝缘子表面的冲击闪络有重大影响;当均勺分布或线性分布的正极性电荷的密度大于25μC/m～2时,表面冲击放电强度减小 ...
