摘　　要：针对特高压输电线路工程施工跨越电力线对电网安全稳定运行影响日趋增大的问题,提出伸缩臂式快速跨越封网装置的设计方案,介绍伸缩臂式跨越架的构成和安装步骤,通过跨越电力线现场应用证明了该装置具备在不停电的情况下快速跨越封网的功能。In UHV power transmission line construction, the crossings between UHV lines and other power lines increasingly affect the power grid. To solve this problem, this paper designs this collapsible-beam fast crossing device, introduces the parts of this device and the assemble procedure. The application in field shows that this device is able to fast crossing and covering the power line underneath.
