均压环加装硅橡胶套对复合绝缘子闪络特性的影响

Gaoya dianqi
雷击是引起输电线路跳闸的主要原因，加强绝缘子的绝缘性能有助于提升架空输电线路抵御雷电灾害的能力。文中主要关注均压环加装硅橡胶套能否改善输电线路耐雷性能这一问题。为此，文中首先开展了雷电冲击电压下绝缘子闪络放电实验，获得了新型绝缘子和传统绝缘子的伏秒特性曲线，结果表明硅橡胶套可以让伏秒特性曲线上移。进一步分析放电发展过程的高速影像发现，上述改善主要是因为硅橡胶套抑制了流注放电的起始和增大了先导放电的路径。基于实验结果拟合的伏秒特性曲线，文中仿真计算了均压环的硅橡胶套对输电线路反击耐雷水平和反击跳闸率的影响，

基于脉冲同步的配电电缆局部放电在线监测及定位方法

Gaoya dianqi
为了解决配网电缆局部放电在线定位难题，文中提出了一种基于脉冲同步的配电电缆局部放电双端在线定位方法，并研制了面向泛在电力物联网的配电电缆在线监测系统。首先，通过向电缆中注入脉冲信号，实现双端系统的时钟同步，并获得高频信号在电缆中的传播速度，解决了到达时间分析方法在配网电缆应用中同步困难的问题，并提出了采用基于能量法估计的局部放电脉冲到达时间，提高局部放电定位结果的鲁棒性。然后，描述了面向泛在物联网的配网电缆局部放电在线监测要求和架构。其次，详细讨论了关键硬件的实现方法 ...
