摘　　要：随着社会经济的不断发展,输电线路的走廊资源日益紧张,因此提高走廊的利用效率至关重要。结合线路规划情况,采用500kV与220kV线路同塔架设,可集约利用走廊路径,大幅降低拆迁费用和建设难度。但采用不同电压等级同塔架设需对线路回路间的电磁感应进行计算,保障线路设备及人身安全。根据线路塔型及导线参数,利用ATP-EMTP软件建立模型,分析了同塔四回线路的感应电压和感应电流机理,为后期工程设计提供参考依据。With the development of social economy,the corridor resources of transmission lines are becoming tense,so it is very important to improve the utilization efficiency of the corridor.500 kV and 220 kV lines been erected on the same tower,which can intensively use the corridor path and greatly reduce the demolition cost and construction difficulty.However,when different voltage lines are erected on the same tower,the electromagnetic induction between circuit lines should be calculated to ensure the safety of line equipment and personal.In this paper,according to the tower model and conductor parameters,using ATP-EMTP to build model,analyze the induced voltage and current four circuit lines on the same tower.Final it can provide reference for future project design.
