Abstract

As a result of the AC technology design assessment completed by the Association of American Railroads (AAR) in 1990, the North American freight railroads have developed a performance specification for a pilot fleet of three-phase asynchronous AC traction locomotives. A preliminary economic analysis has shown that the viability of AC traction in North America lies in the fleet reduction that the specification performance levels, when implemented, can bring. However, if fleet reliability does not increase in proportion to fleet reduction, then both projected savings and viability are reduced. A study of maintenance and reliability is performed for several key European fleets of AC traction locomotives, defined in the initial AAR design assessment. Several visits were made to these European railways to gather information and review their service experience. The resulting information is revealed, with respect to the AAR Performance Specification for AC Traction Systems. The European information centers on early failure data and current reliability targets for new equipment. The performance specification is also outlined.<>

交流牵引系统的维护和可靠性概述

作为美国铁路协会(AAR)于1990年完成的交流技术设计评估的结果，北美货运铁路制定了一套三相异步交流牵引机车试验车队的性能规范。初步的经济分析表明，交流牵引在北美的可行性在于规格性能水平的实施可以带来的车队减少。然而，如果机队的可靠性没有随着机队数量的减少而增加，那么预计的节约和生存能力都会降低。在最初的AAR设计评估中，对几个主要的欧洲交流牵引机车车队进行了维护和可靠性研究。我们对这些欧洲铁路进行了几次访问，以收集信息和审查他们的服务经验。由此产生的信息是揭示，相对于交流牵引系统的AAR性能规范。欧洲的信息集中在新设备的早期故障数据和当前可靠性目标上。还概述了性能规格。
