无跨越架带电跨越施工技术应用

随着经济的高度发展，对电力的需求迅猛增长，高压输电线路建设突飞猛进，交叉跨越越来越复杂，仅采用搭设脚手杆跨越架的方式难以解决在复杂地势条件下跨越电力线路的问题。以500kV王南甲乙线π入渤海变送电线路新建工程为例，详细叙述了采用封网方式，对甲线处于山上的8～9号之间无跨越架带电跨越2条66kV带电线路的施工工艺、方法、施工原理，对今后的输电线路带电跨越施工具有一定的参考意义。

The Use of Constrnction Technology for Live Cross without Spanning Structure

Along with economic development, the electricity demand is increasing, so is the HV transmission line construction. Cross and span problem mainly deals with transmission line, which is becoming more and more complicated. So it is difficult to cross transmission line in complex topography with staging. Take 500 kV Line Wangnan AB that π turn into Bohai as an example, which live crossing 2×66 kV live line between No. 8 to 9 on the hill after closing network without crossing structure. The construction tech- nology, methodology and principles of which provides references for transmission line live spanning.
