研发了一种在线检测零值绝缘子的装置,并介绍了该装置在绝缘子上的攀爬及其检测过程。靠近导线侧绝缘子钢帽上的电位较高,为了防止检测装置在钢帽上攀爬过程中钢帽对抓手悬浮放电引起控制电机的损坏,本文运用电磁暂态仿真软件ATP/EMTP搭建了悬浮放电的转移电流模型,并用Ansys软件求取转移电流模型中的参数。考虑了钢帽与抓手间距离d以及抓手自身电感L对转移电流的影响。研究结果表明:转移电流的幅值与距离d成反比,电位转移过程中释放的瞬态能量与间距d成反比;转移电流的幅值与抓手电感L成反比,电位转移过程中释放的瞬态能量W与抓手电感L无关。在研究结果的基础上,提出在抓手上增加弹簧垫片的方法...

An on-line detecting device of the low&zero insulators is developed.Besides,the device climb on insulator strings and its detection process is also introduced.The potential of steel caps,which is near the transmission line,is higher.In order to prevent the suspended discharge damaging the motor which is used to control detecting device climb on steel caps,the transfer current model of suspended discharge is established by ATP/EMTP software and the parameters of transfer currents model is calculated by Ansys software.The effect of different distance of gaiter from steel hat and inductor of gait...
