ZD-6型电动转辙机“接点反弹”的故障分析及预防

Fault Analysis and Prevention of"Contact Rebound"of ZD-6 Electric Switch Machine

地铁线网的不断拓展,正线及车辆段对ZD-6型电动转辙机使用要求越来越高。针对ZD-6型电动转辙机摩擦联结器的结构特点,分析现场转辙机运作时出现“接点反弹”现象及摩擦电流不达标的问题原因,提出一些日常维护处理方法。

With the continuous expansion of the subway network,the main line and depot have higher and higher requirements for the use of ZD-6 electric switch machine.In view of the structural characteristics of the friction coupling of ZD-6 electric switch machine,this paper analyzes the causes of the"contact rebound"phenomenon and the problem that the friction current does not up to standard during the operation of the on-site switch machine,and puts forward some daily maintenance methods.
