商阜动车组车载磁钢自动过分相试验失败的原因分析及建议

Cause Analysis and Suggestion on Failed Onboard Automatic Neutral Section Passing Test of EMUs with Magnetic Steel on Zhengzhou-Fuyang High Speed Railway and Shangqiu-Hefei-Hangzhou High Speed Railway

结合新建商合杭―郑阜高铁联络线绝缘锚段关节改造为6跨分相关节,并按设计规范要求设置分相磁钢。在联调联试期间,动车组搭载磁钢自动过分相试验时,产生了自动过分相失败情况。经过现场核实和原因分析,提出问题解决方案和建议,为后续工程设计和实施过程提供参考,避免对行车组织带来不利影响。

Insulated overlaps along the connecting line of the new Zhengzhou-Fuyang High Speed Railway and the Shangqiu-Hefei-Hangzhou High Speed Railway were transformed into 6-span neutral section overlap,and magnetic steels for neutral section were set in accordance with design specifications.This paper examines failed onboard automatic neutral section passing test of EMUs with magnetic steel in the integration commissioning&test.Field check and cause analysis were conducted,and solutions and suggestions were put forward as a reference in future engineering design and implementation process,to avoid adverse impact on traffic organization.
