摘要
介绍了地下铁道供电系统中降压变电所内动力变压器容量计算的常用方法,根据计算中发现的问题及投入运营设备使用情况的调查,提出“不强调双台变压器负荷率≤70%及降低同时系数”的观点,以利于降低设备的一次投资和资源的利用。
This paper introduces a routine method in calculating the capacity of power transformer in step-down substation of Metro. According to the problems occurred in calculation and investigation of operational equipment, it raises the point of 'no emphasizing on both of load ratio of dual transformer to be equivalent or less than 70 percent and reducing simultaneity factor', which is good for reducing the investment of equipment and utilization of resource.
