摘要
根据复合绝缘子耐张串在220kV线路的应用情况,采用导线-绝缘子动态模型对运行中的复合绝缘子耐张串所承受的各种动态荷载进行计算分析,确定最大动态载荷的大小,以便在复合绝缘子耐张串设计时,合理确定其安全裕度或安全系数,保障复合绝缘子耐张串的安全可靠性。
According to the applications of composite insulator tension strings to 220 kV transmission lines, various dynamic loads on running composite insulator tension strings are computed and analyzed with the conductor-insulator dynamic model, and the maximum dynamic load is ascertained, so that in the design of composite insulator tension strings the safety margin or coefficient can be determined reasonably and the security and reliability of the tension strings can be guaranteed.
