Abstract

The electrical transmission between moving parts requires contact pairs such as rolling rings, sliding rings, connectors, etc. These functional contact pairs can be defined as current-carrying frictional pairs because they need to bear the transmission of current while enduring friction and wear. The rough current-carrying frictional pairs are typical contact surface withstands the load of force, heat, and electricity, resulting in the unique contact characteristics of the current-carrying pair. The research progress of current-carrying tribology has been reviewed in this paper. The correlation mechanism between tribological performance and current-carrying performance has been summarized. The composite and competitive relationship between mechanical damage and electrical damage has been discussed. Methods for evaluating the dynamic performance of current-carrying tribology has been proposed. The spatiotemporal non-uniformity of current-carrying frictional damage has been revealed. Future research trends are expected at the end.

输电中载流摩擦特性的研究进展

运动部件之间的电气传输需要滚动环、滑动环、连接器等接触对。这些功能性接触对可定义为载流摩擦对，因为它们需要在承受电流传输的同时承受摩擦和磨损。粗糙的载流摩擦副是典型的接触表面，能承受力、热和电的负荷，从而形成了载流摩擦副独特的接触特性。本文综述了载流摩擦学的研究进展。总结了摩擦学性能与载流性能之间的关联机理。讨论了机械损伤和电气损伤之间的复合竞争关系。提出了载流摩擦学动态性能的评估方法。揭示了载流摩擦损伤的时空不均匀性。最后展望了未来的研究趋势。
