摘要:
阐述了目前3种接触网刚柔过渡形式各自的原理及优缺点，提出刚柔过渡在地铁出入段小半径曲线线路上设置需满足的条件。比较了刚柔过渡处竖直悬吊及悬臂式悬吊等两种悬挂方式，推荐小半径曲线线路采用竖直悬吊方式以保证接触线的接触面与受电弓平行。建议设计时可根据线路条件实际放样，以此来进行接触网刚柔过渡处的平面和立面布置，并给出了平面和立面布置的详细设计步骤及注意事项。
Abstracts:
Principle, advantages and disadvantages of the current three fromats of catenary rigid flexible transition section are expounded, and the required conditions of setting rigid flexible transition on metro inlet/outlet line small\|radius curve are demonstrated. Two hanging ways at the rigid flexible transition section, namely, vertical suspension method and cantilever suspension method are compared. It is recommended to use vertical suspension to ensure the interface of contact line parallel to pantograph for small\|radius curve line. It is suggested to do lofting according to the actual line conditions during design, in order to carry out plane and facade layout of catenary rigid flexible transition section, of which detailed design steps and precautions are listed.
