摘要
Abstract
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.关键词
