Development of Virtual Tools for the Validation Study of Rigid Catenary Installations
, 2023 AbstractElectrification systems in the railway field have evolved over time, adapting to the new needs that have arisen as technology advanced. The applicable standards seem to leave the systems in which the overhead contact rail is implemented so far in the background, resulting in references to it that are clearly insufficient, even in the most ...

Development of Long Span Type Overhead Rigid Conductor Line of Catenary System
IEEJ Transactions on Industry Applications, 1998 An overhead rigid conductor line in a tunnel is free from the fear of disconnection because the contact wire is not tensioned, and it is superior in maintenance saving. In order to introduce this in open sections, we have developed “a long-span-type overhead rigid conductor line of catenary system.” This contact line structure consists of a contact ...

A Two-Stage Detection Method of Rigid Pantograph Catenary Contact Points Using DCNNS
Journal of Physics: Conference Series, 2021 Abstract Pantograph catenary contact point is an important monitoring object during pantograph catenary operation, which reflects the state of pantograph catenary operation. However, due to the relatively small contact area of the target area, it is still a challenge to locate the contact point quickly and accurately.
