摘要
随着电网规模不断扩大,各电压等级线路回数越来越多,高电压等级输电线路之间的交叉穿越是电网建设高速发展的必然现象。如何实现电力线路交叉穿越,涉及投资、停电、运行维护等一系列问题。针对线路电压等级、回路数及塔型的不同,研究了不同交叉穿越方式,并对工程造价进行详细对比分析,提出了输电线路交叉穿越的通用技术原则,可用于指导工程实践。
With the continuous expansion of power grid, more and more transmission lines are constructed. Line crossings among high voltage transmission lines are inevitable because of the power grid construction high-speed development. The investment, power outages, operation and maintenance, and other factors affect realizing power line crossing. In view of different voltage levels, line circuit numbers and tower types, different line crossing modes are studied, and the project cost are compared and analyzed in detail. Series of general technical principles on transmission lines crossing are proposed to guide the engineering practice.
