摘要
针对S700K转辙机沙尔特堡接点组存在冷凝天气转换异常、接点组偶发性虚接、可维护性较低等问题,开展接点组改造项目,由SRT6加强型排骨式接点组替代沙尔特堡接点组.通过分析该技改项目,总结改造思路和既有线施工难点,为其他地铁转辙机接点组改造提供参考.
To deal with such problems in the Saltburg contact group of S700K switch machine as abnormal conversion in a condensation day,occasional virtual connection and low maintainability,the renovation of contact group was launched by replacing Saltburg contact group with reinforced sparerib contact group.By analyzing this project of technical transformation,the ideas of transformation and the difficulties of construction in existing line are summarized,providing reference for the transformation of switch machine's contact group in other metros.
