桥巩水电站离相封闭母线安装要领

Gist of Isolated-phase Enclosed Bus Installation at Qiaogong Hydropower Station

主要叙述桥巩水电站离相封闭母线的安装方法、工艺流程、质量控制步骤及质量指标,并指出封闭母线安装过程中应注意的有关事项。桥巩水电站离相封闭母线安装方法切实可行,有效地克服离相封闭母线体积大,长度长,重量重,给安装施工带来的困难。工序安排合理,对母线中心线测量放样、安装固定和焊接三个关键工序要从严控制,避免了返工浪费,确保了工程质量和按期交工。桥巩水电站自投产发电以来运行安全可靠,施工企业既提高经济效益,业主的投资又早日得到回报。

The text mainly covers installation method, technological process, quality control procedures and quality index of isolated-phase enclosed bus of Qiaogong Hydropower Station, and points out precautions in the installation of such bus. The way of bus installation at the station is feasible for it effectively overcomes difficulties brought about by such large, long and heavy bus. Procedures involving survey and setting out of bus centerline, installation and fixation, and welding are reasonably arranged to ensure engineering quality and completion on schedule. The station has been operating safely and reliably since it is put into operation to generate electricity. It not only helps increase economic benefit of the construction enterprise but also yields investment returns to the owner in a short term.
