浅谈铁路变配电所直流电源系统的选择

Briefly Talk on Selection of Direct Current Power Supply System in Transformer Substation

介绍了铁路变配电所直流电源系统的发展,对组成系统的主要部件即蓄电池、充电浮充电机及控制系统进行了分析,阐述了直流电源系统选择的实质及容量的确定,建议一般铁路变配电所宜选用带镉镍蓄电池或免维护全密封铅酸蓄电池的自控型直流电源成套装置,建议将建立"三遥"(遥控、遥测、遥信)电力系统的变配电所直流电源系统选用全自动智能型带有"三遥"接口的直流电源屏。

First, the paper gives an introduction about the development of direct current power supply system in railway transformer substation. Second, it gives an analysis on the storage battery, the floating charger and the controlling system which consist of direct current power supply system. Third, it elaborates the essence of selection of direct current power supply system and how to determine its capacity. In the last, it suggests direct current power supply system with sealed lead/acid battery or cadmium-nickel battery should be selected in general railway transformer substation and full-automatic intelligence type dc power source screen with 'three remote'port (remote control, remote measure, remote communication) should be selected in direct current power supply system in transformer substation with the function of 'three remote'.
