石太客运专线牵引变电所自投防拒动研究

Researches on Failure to Trip of Traction Substation's Automatic switching-in on Shijiazhuang-Taiyuan Passenger Dedicated Lines

通过对石太客运专线牵引变电所自投拒动问题的研究,找到了自投拒动的根本原因是国产综合自动化设备与法国的真空断路器之间电气参数不匹配,进而提出了解决问题的具体方案并组织实施,消除了设备隐患。

The article through the researching of the automatic switch operation failures in the railway traction substations,Shijiazhuang-Taiyuan passenger transport railroad line,found the main reason of this kind of problem.The main reason was the electric parameter’s mismatching of between the homemade automatic facilities and the Francemade vacuum breakers.And then the author gave a proposal and tried to carry it out.Finally,the proposal worked and eliminated the operation failure of the automatic facilities.
