|
摘要
输电线路绝缘子污闪事故已占到了整个电力系统事故的第二位。实现绝缘子的放电实时监测,是目前输电线路安全运行迫切需要解决的问题。本文着重探讨了目前国内外对线路绝缘子放电的一般监测方法,并针对绝缘子放电脉冲电流伴随产生的超高频电磁波,采用了的一种全新的远距离在线监测,设计了用于监测的螺旋聚束天线阵列。研究了监测所需的软硬件系统及线路放电绝缘子的定位方法,以实现对线路绝缘子污闪的实时监测。
Flashover of power transmission line insulator has become the second most accident in power system. To perform the real-time monitor of insulator is a crucial task for the safety of electric power system. This paper discusses the general monitor methods of insulator discharge at home and abroad, and uses a new long distance monitoring method for the UHF Electromagnetic Waves accompanying with discharge pulse current of insulator flashover, and designed the axial mode helix antenna array for monitoring insulator. The paper have studied the software and hardware system for monitoring and locating method for power transmission line discharging insulators, for taking the real time monitor into reality for pollution flashover of power line insulators.
