摘要
京广高铁开通以来发生多起轨道电路改方失败的故障,分析原因是由于改方过程方向继电器(FJ)误动造成。由于FJ误动的发生具有随机性和突发性,因此重点对其进行分析并制定对策。
Since the opening of Beijing-Guangzhou high-speed railway, direction changing errors often occur to track circuit. The direction changing errors is often caused due to real-operation of the directional relay FJ. Because the occurrence of directional relay＇s mal-operation is random and sudden, we focus on analyzing the causes of directional relay＇s mal-operation and determining countermeasures.
