简谈降低转辙机内部接点故障率的技术改造措施

Technical Transformation Measures to Reduce Failure Rates of Internal Contacts of Switch Machine

从苏州轨道交通以往发生的转辙机内速动接点组故障案例出发,对各类型接点故障原因进行分析,并结合现场实际情况有针对性地提出相应的技改措施并加以应用,以达到降低速动接点组故障率,提高运营行车效率的目的。

Based on the past failure cases of quick-acting contact groups in switching machines of Suzhou Rail Transit,this paper analyses the causes of various types of contact failures,and puts forward corresponding technical improvement measures and their application according to the actual situation in the field,in order to reduce the failure rates of quick-acting contact groups and improve the operation efficiency.
