本文简要介绍了国内外常用的电力机车自动过分相方案,并对其优缺点进行分析比较。对国内采用的车上自动控制断电过分相方案运用中存在的问题进行了分析,提出了增强过分相装置的可靠度,开发过分相状态记录、地面磁枕检测、监控装置语音提示、加快冗余控制研究和加强管理措施,提升电力机车过分相的可靠性。
This article briefly introduces the automatic over-phase scheme of electric locomotive commonly used both at home and abroad, and compares its advantages and disadvantages. The problems existing in the application of auto-control over-power-over-phase in vehicle are analyzed in this paper. The reliability of over-phase device is raised, the record of over-phase condition is developed, the detection of ground magnetic pillow, the voice prompt of monitoring device and the acceleration of redundant I control research and strengthen management measures to improve the reliability of over-phase electric locomotives.
