摘　　要：输电线路风偏闪络事故直接影响电网的安全稳定运行,近年来各电网企业正有序开展技术改造。复合材料构件在输电线路中的推广应用,为输电线路防风偏改造提供了新思路、新方法。对于酒杯塔,可采用中相牵制、边相复合材料构件支撑的技术方案以避免风偏闪络的发生。该改造方案造价可控、停电时间短、施工便捷,能够满足改造工程对投资、工期和实施便利性的要求。同时,在其他类型的杆塔和线路中,也可灵活该技术进行防风偏设计。Flashover caused by windage yaw directly afect the safe and stable operation of power grid, and power grid enterprises are ordered to carry out technical transformation on it in recent years. Popularization and application of composite material component in transmission lines provide new ideas and methods for the windage prevention. For cup-type tower, windage yaw can be controlled by a combined technological scheme presented as constraining the middle conductor and supporting the outer conductor with GFRP components. Due to such a scheme, reconstructed projects will have advantages of controllable cost,short outage time and convenient construction. Moreover, the aforementioned scheme can also be applied to other types of tower and transmission lines.
