瓷盘型悬式绝缘子串劣化状态自动检测装置研究

Dianci bileiqi
为提高高压输电线路瓷质绝缘子串劣化或低/零值带电检测的准确性，研制了可用于无人机搭载的自动可变间隙火花放电检测装置。首先结合声-光-电检测实现了绝缘子分布电压的自动和准确测量。其次在实验室搭建了间隙放电试验平台，试验确定了球形间隙放电电压与间隙距离的对应关系，据此整定了可变火花间隙测量装置的间隙距离。最后建立了绝缘子串及检测装置等效模型，利用场路结合法研究了检测装置介入对检测结果的影响。研究结果表明，可变间隙距离的火花放电检测装置对绝缘子串原始电场影响小，高精度检测有助于准确地判断绝缘子片劣化程度 ...

10 kV架空线路单相安装方式下并联间隙保护距离研究

Dianci bileiqi
采用单相安装并联间隙，可以显著提升10kV架空线路下感应雷和雷击横担时的耐雷水平。为使该措施得以应用，还需要进一步确定并联间隙的保护距离。本研究以线路耐雷水平不下降为原则，提出了考虑感应雷过电压、雷击横担2种雷击方式，以及线路来波和雷击当基杆塔2种不同雷击部位时，并联间隙保护距离的计算方法；并基于放电试验得到的P-15绝缘子及间隙的伏秒特性曲线，以10 kV架空线路典型设置的杆塔、导线和绝缘子等为实例，仿真计算了上述不同情况下单相安装并联间隙的保护距离。在考虑线路来波及雷击当基杆塔，在感应雷过电压 ...
