    Abstract Calculation result table and conversion method are presented to satisfy maximum radius of voltage?鄄drop and grounding fault protection through voltage?鄄drop verification and thermal stability verification of distribution line，analysis of calculation method of grounding fault protection on the basis of such characteristics as long distance of low?鄄voltage power distribution and a number of coordination links，etc. of railway passenger station projects. Selection and setting of low?鄄voltage circuit breaker for railway passenger station are also discussed.

    Key words Railway passenger station Low?鄄voltage power distribution Voltage?鄄drop verification Thermal stability verification Setting calculation of low?鄄voltage circuit breaker

 

    摘 要 针对铁路客运站房项目低压配电距离长、配合环节多等特点，通过对配电线路电压降校验、热稳定校验及接地故障保护计算方法的分析，给出满足电压降、接地故障保护最大半径的计算结果图表及换算方法。并对铁路站房低压断路器的选择和整定进行论述。
