摘　　要：介绍了某座变电站500 kV SF_6电流互感器故障的发生过程,并分析出该故障发生的原因是设备内部均匀的电场分布遭到破坏使电场畸变,产生局部放电,最终导致绝缘支撑杆发生沿面击穿闪络,并针对该故障进行了总结。Smart grid need wireless access technology to solve the last mile access, and provided a high bandwidth wireless access platforms to meet the access needs of a wide variety of business. TD - LTE technology was more suitable for promoting the development of smart grid from the standpoint of the data rates, capacity, latency, security and other aspects.

关 键 词：SF6电流互感器 绝缘支撑杆 故障分析
