对雁田抽水站原有的蓄电池组的容量损失进行了分析。为适应老式泵站油开关瞬间大电流合闸的要求进行更新,选用纤维镉镍电池组,并对其原理和特性进行了叙述。介绍直流镉镍充电装置硬件结构方框图、系统原理和在泵站中的实际应用效果。 The capacity loss of the original battery in Yantian Pumping Station was analyzed. In order to adapt to the requirement of the instantaneous large current closing of the oil switch of the old pump station, the fiber nickel cadmium battery was selected and its principle and characteristics were described. This paper introduces the hardware structure block diagram, system principle and practical application effect of DC Ni-Cd charging device.
