山东环网1000 kV特高压线路跨越电气化铁路施工方案设计与实施

Design of the Construction Scheme for a 1000 kV Super-high voltage Power Transmission Line over Railway in Shandong Loop Grid and Impletemention

山东环网1000 kV特高压跨越瓦日铁路及配套设施,其施工高度超过24 m,跨越架搭设和跨越施工风险均达到四级,需编制专项施工方案。文章实测和复核现场跨越点各技术参数,合理选取导线滑车悬挂方式,通过跨越架各技术参数计算,设计跨越施工方案,确保了跨越施工过程安全,可为类似跨越施工提供参考。

The height of the constrction facilities for the 1000 kv super-high voltage power transmission line over the Wari railway in Shandong loop gird is over 24 meters,the risk of the spanning frame building and spanning operation of the line is at 4 level,a special scheme for the spanning construction is necessary.In this paper,the measured parameters at the cross point are validated,the reasonable suspension method of conductor pulley is selected,parameters of the spanning farme are carefully calculated,in end the special scheme for the spanning construction of the line ovre the railway is proposed that can provide other similar construction an usefule reference.
