摘　　要：根据某110 kV GIS变电站实际直流负荷情况,在采用阀控式密封铅酸蓄电池设备的基础上,对蓄电池的标称容量、数量、均衡充电电压、放电终止电压、高频开关充电装置模块参数选择进行详细计算,最终确定该变电站蓄电池配置设计方案,即容量200 Ah、数量106个,单体蓄电池均衡充电电压2.33 V、放电终止电压1.87 V,采用1组高频开关充电装置,并选取5个10 A的模块进行蓄电池充电。该设计方案可确保变电站直流系统的安全、稳定运行。The paper introduces the detailed calculations of the battery nominal voltage, the number of battery, equalizing charge voltage, final discharging voltage, the parameter selection of high-frequency switch charger moduie according to DC load in some 110 kV GIS substation, based on a valve regulated sealed lead-acid battery. The result of calculation reaches the design, the battery normal capacity is 200 Ah, the number is 106, equalizing charge voltage 2.33 V and discharge charging device switching frequency charges for finish voltage 1.87 V the battery are used, per battery, and a 5 modules of 10 A are chosen. The scheme ensures the DC system in substation runing safely and stability.
