交流500kV天广一回送电线路架空绝缘地线的运行分析

Operation - Analyzing on the Overhead Insulation Grounding Line of 500kV AC Tian - Guang 1st Transmission Circuit

本文通过对交流500kV天广一回送电线路架空绝缘地线在运行中发生的事故、障碍和异常情况的分析,从而提出架空绝缘地线在运行中应注意问题:1、优化设计,控制绝缘地线电磁感应电压和电流在1000伏和lO安以下;2、精心选择绝缘地线专用绝缘子的型号并定期对绝缘子的绝缘强度和间隙值进行检查;3、在绝缘地线上作业和测量杆塔接地装置的接地电阻时,必须做好人身安全措施;4、加强教育培训,不断提高生产人员的技术水平。

Analyzing on the accidents, obstructions, and abnormal cases happened in operation of the overhead iasulation grounding line of 500kV AC Tina Guang 1st transmission circuit, the author presents some points which should be put more attention to in operation of the overhead insulation grounding line.
