摘　　要：核电站常规岛的充电装置给蓄电池充电时,蓄电池的浮充电流和均充电流的数值相差近百倍。为了确定应急柴油机启动后通过充电装置给蓄电池充电的电流(功率)是浮充电流(功率)还是均充电流(功率),针对柴油机加载时蓄电池可能发生的工况,分别进行模拟实验。结果表明:此时的充电电流既不是恒定的均充电流,也不是浮充电流,而是随时间快速衰减的电流曲线。For the design of nuclear power plant’s conventional island,how to determine the current(power)of the battery charger is an important factor when optimizing the capacity of the emergency diesel engine.To determine the current(power)of the battery charger is floating or equalizing current(power)after emergency diesel engine starts up,the experiment is carried out according to the possible conditions of the batteries when the engine is loaded.The result shows that the charging current at this time is neither a constant equalizing charging current nor a floating charging current,but a fast decaying current curve with time.
