摘　　要：接触器作为高速动车组控制系统重要元件之一,具有不可替代的作用。但因接触器自身结构特点,常发生偶发性故障,影响动车组运行。为避免偶发性故障,设计一款接触器可靠性分析装置用于接触器失效预测,具有重要研究意义。该装置以失效理论为基础,对接触器电压电流特性进行综合分析。结合日常检修对关键接触器进行诊断筛查,及时更换不符合技术参数要求的接触器,避免动车组在运行途中发生接触器类故障。此外,该装置还可以采集故障时刻接触器相关技术参数,为接触器失效研究提供准确、客观数据支撑。As one of the important components in the control systems of high-speed EMUs,the contactors play an irreplaceable role,but due to the characteristics of their own structure,occasional failures often occur,affecting the operation of the EMUs.In order to prevent the occurrence of occasional failures,it is important to design a reliability analysis device for contactor failure prediction,which holds significant research value.The device uses failure theory as the basic theory to perform a comprehensive analysis of contactor voltage and current characteristics.Based on daily maintenance,key contactors undergo diagnostic screening.Those with technical parameters that do not meet the requirements are promptly replaced to avoid failures related to contactors during the operation of the EMUs.In addition,the device can collect relevant technical parameters of the contactors at the moment of failure,providing accurate and objective data support for contactor failure studies.
