Optical device for determination of contact force of current collector, has optical sensor arranged within trailer area, at or in, overhead traction line section following overhead traction line section running towards driving direction

摘要

The device has an optical sensor (54,55,56) arranged within the trailer area (71), at or in, the overhead traction line section following the overhead traction line section (21) running towards the driving direction. The overhead traction line is provided with overhead traction line sections arranged after one another mechanically decoupled from each other along the overhead contact line (2) towards driving direction of the railway vehicle (31).
