电缆终端杆塔及终端站在城市电网中的应用研究

Research of Cable Terminal Tower and Station in Urban Power Grid

随着电网技术的发展,架空电缆混合线路在城市电网中的应用日益广泛。在电缆和架空线路的交界点,一般采用电缆终端杆塔或终端站的方式。本文对国内常用的各种类型电缆杆、终端塔及终端站进行调研研究,对技术特点和适用性进行总结,形成可指导设计的技术导则。最后通过案例工程的试点应用,对不同方案的技术经济比较,推荐适用工程的终端塔方案,为今后的混合线路的电缆终端杆塔或终端站选型及设计提供经验借鉴。

With the development of power grid technology,the cable mixed high voltage overhead lines is widely used in urban power grid.At the junction of cable and overhead line,the cable terminal tower or station is generally used.In this paper,various types of terminal towers and stations are studied,and the technical features are summarized that can guide the design.Finally,the project is applied which provides experience for the design of cable terminal tower and station in the future.
