Key Faults and Treatment Strategies Analysis of HXD1C Electric Locomotive

摘要

HXD1C型电力机车是中国干线货运中的六轴7200 kW交流传动主型机车，长期承担山区干线、重载区段和高密度货运牵引 任务。该型机车采用牵引变流器、辅助变流器、网络控制系统与模块化高压设备协同工作的总体方案，系统集成度高，故 障往往具有联锁多、跳主断快、重复报警强和现场判断难度大的特点。受电弓、高压绝缘、辅助供电以及制动风源链路一 旦异常，通常会直接影响机车牵引建立、途中维持和安全停车。本文围绕HXD1C型电力机车运用中具有代表性的重点故障 展开分析，并结合现场检修逻辑提出对应处理策略。

Abstract

The HXD1C electric locomotive is a six-axle, 7200 kW AC-driven main-type locomotive used in China’s trunk freight transport, long-term undertaking traction tasks on mountainous trunk lines, heavy-load sections, and high-density freight operations. This locomotive adopts an overall solution featuring coordinated operation of traction converters, auxiliary converters, network control systems, and modular high-voltage equipment, with high system integration. Its faults often exhibit characteristics such as multiple interlocks, rapid main circuit breaker tripping, intense repeated alarms, and significant challenges in on-site diagnosis. Any abnormalities in the pantograph, high-voltage insulation, auxiliary power supply, or braking air source linkage can directly impact traction establishment, mid-trip maintenance, and safe parking. This paper analyzes representative key faults encountered during the operation of HXD1C electric locomotives and proposes corresponding handling strategies based on field maintenance logic.
