Abstract
Research purposes and methods: Although the additive wire of OCS doesn’t contact with pantograph directly, its performances are closely related to traffic safety. In the early construction of high-speed railway in China, the design of the additive wire at converting point didn’t take into account all related issues and resulted in many problems. The paper, with reference to the design of additive wire conversion on different high speed lines with conventional tunnel profile and station layout, looks for the design suitable for lines with different conditions to guarantee the insulation distances between the additive wire and catenary, between the additive wire and buildings and to meet the requirements for economy and landscape at the same time. Research conclusions: with reference to standards, specifications and engineering practices, the paper conducts comparison of conversion designs of additive wire, and analysis of the design in many respects, such as the insulation distances, the difficulties in installation and construction, capital costs and landscape. Finally, depending on the comparison results, the paper offers recommended plans for different circumstances and provides references for future design and construction.关键词
