High speed trains receive traction electrical energy from a high-voltage catenary via a pantograph catenary system (PCS). As the velocity of trains increases, the traditional PCSs face significant challenges, such as strong aero resistance under high-speed conditions, severe electrochemical corrosion caused by poor contact between the pantograph strip and the catenary, harmful wear both on the pantograph strip and the contact wire produced by high-speed sliding friction between them, etc. The effectiveness and reliability of the PCS has a direct impact on the performance and safety of the HTS power supply. In order to alleviate some of these bottleneck effects related to the operation of the currently used PCSs, especially under high-speed conditions, this paper proposes a novel configuration where rotatable pantograph rollers replace the currently used pantograph strips. As the sliding friction is now replaced by rotating friction, this has numerous benefits, such as less friction heat, better heat dispersion and improved catenary-tracking performance. Moreover, should the whole system be modularized, it could adapt to different levels of traction power through adjusting the number of rollers.

高速列车通过受电弓悬链线系统（PCS）从高压悬链线接收牵引电能。随着列车速度的提高，传统的PCS面临着严峻的挑战，例如在高速条件下的强耐空气腐蚀性，受电弓带和悬链线之间接触不良导致的严重电化学腐蚀，受电弓带和触头上的有害磨损PCS的有效性和可靠性直接影响HTS电源的性能和安全性。为了减轻与当前使用的PCS的操作有关的某些瓶颈效应，尤其是在高速条件下，本文提出了一种新颖的配置，其中可旋转的受电弓辊代替了当前使用的受电弓条。由于现在用旋转摩擦代替了滑动摩擦，因此具有许多好处，例如摩擦热更少，热分散更好以及悬链线跟踪性能得到改善。此外，如果整个系统模块化，则可以通过调节辊数来适应不同级别的牵引力。
