摘　　要：为有效解决复合绝缘子在750kV输电线路耐张串的应用问题,提出对复合耐张绝缘子伞形的优化措施、芯棒脆断的防护措施以及在施工和运行维护中对复合耐张绝缘子的保护措施,从而避免750kV输电线路污闪对系统造成巨大冲击,保证750kV输电线路的安全稳定运行。In order to effectively solve the problems of tension composite insulator applied in 750 kV transmission lines,some measures are proposed in this paper,such as the optimization of umbrella-type tension composite insulator,the protection of the mandrel against brittle fracture,and the protection of tension composite insulator in construction and operation.These measures could make 750 kV transmission lines avoid the tremendous impact of the pollution flashover and ensure the safe and stable operation of 750 kV transmission lines.
