摘要
由于直流电源输出电压稳定,纹波较小,在电力系统中被广泛作为各种装置的控制电源和操作电源。而蓄电池组则是直流系统的唯一后备保障。长期以来,镉镍蓄电池由于其放电率高,使用寿命长,曾被广泛使用。
Thanks to its stable output voltage and low ripple wave, DC power supply is widely used as control power and operational power for all kinds of apparatuses. And sinntered battery is the only backup support for DC system. Ni-Cd Sintered Battery has beenwidely applied for a long time for its enduring validity and high discharge rate.
