摘要
对地铁TN-S低压配电系统中主进线开关、母联开关、馈线开关、双电源切换装置开关极数选择与配合进行分析总结,提出选择方案,并分析可能存在的问题,为地铁类似工程建设提供建议。
The analysis and summarization are made for selection and coordination of switch poles for main incoming line switches,bus bar switches,feeder switches and dual-source switching devices in subway TN-S low voltage power distribution systems,the selection schemes are put forward and the potential problems are analyzed,providing references for construction of similar subway projects.
