摘　　要：动车组具有优异的惰行性能,给接触网故障临时抢通设置无电区、降弓区创造了条件。通过组织动车组惰行试验和对试验数据统计分析,初步掌握了不同速度、不同坡度条件下动车组惰行规律。结合高铁线路实际,制定每个供电单元(供电臂)惰行方案,对高速铁路利用动车组惰行实施接触网故障快速抢通进行了有益的尝试与实践。The Electric Multiple Unit （EMU） has very excellent idle running performance, providing conditions for setting the neutral zone and pantograph lowering zone for emergency repair of overhead contact system faults. On thc basis of organizing the EMU idle running test and analysis of test data statistics, the idle running regularities of EMU under different speeds and different running gradients have been known preliminarily. With connection of high speed railway practices, the idle running scheme for each power supply section （power supply arm） is established, and uscftl experiments and practices have been performed for emergency repair of OCS faults by implementing the idle running ol EMU on high speed railway.
