EVADA蓄电池性能的影响因素：

电池是个单个的“原电池”组成，每一个原电池电压大约12伏，原电池串联起来就形成了电压较高的电池，一个12伏的电池由6个原电池组成，24伏的电池由12个原电池组成等等。UPS的电池充电时，每个串联起来的原电池都被充电。原电池性能稍微不同就会导致有些原电池充电电压比别的原电池高，这部分电池就会提前老化。只要串联起来的某一个原电池性能下降，则整个电池的性能就将同样下降。试验证明电池寿命和串联的原电池数量有关，电池电压就越高，老化的就越快。UPS容量一定时，设计时应尽可能让电池电压低，这样UPS电池寿命就越长，对于电池电压一定时，应选择数量少电压高的原电池串联的电池，不要选择数量多电压低的原电池串联的电池。有些厂家UPS的电池电压比较高，这是因为容量一定时，电压越高，电流就越小，就可选用较细的导线和功率较小的半导体，从而降低UPS成本。容量1KVA左右的UPS的电池电压一般为24～96V。

Influencing factors of Evada battery performance:

The battery is a single "primary battery". Each primary batteryhas a voltage of about 12V. When the primary batteries areconnected in series, they form a battery with a higher voltage. A12V battery is composed of 6 primary batteries, a 24V battery iscomposed of 12 primary batteries, etc. When the ups battery ischarged, each primary battery connected in series is charged. Ifthe performance of the primary battery is slightly different, thecharging voltage of some primary batteries will be higher than thatof other primary batteries, and these batteries will age inadvance. As long as the performance of a primary battery connectedin series declines, the performance of the whole battery will alsodecline. The test shows that the battery life is related to thenumber of primary batteries in series. The higher the batteryvoltage is, the faster the aging is. When the ups capacity isfixed, the battery voltage shall be kept as low as possible duringthe design, so that the longer the ups battery life is. When thebattery voltage is fixed, the batteries with small quantity andhigh voltage in series shall be selected instead of the batterieswith large quantity and low voltage in series. The battery voltageof some ups manufacturers is relatively high, because when thecapacity is fixed, the higher the voltage is, the smaller thecurrent is, and the thinner wire and the semiconductor with smallerpower can be selected, so as to reduce the cost of ups. The batteryvoltage of ups with capacity of 1kVA is generally 24-96v.

4.3   安全性特点分析

(1)采用双变换在线式设计,保障用户的精密设备供电质量,市电与电池供电为零切换时间,为用户负载提供纯净的正弦波安全可靠的电源,延长了设备的使用寿命。

(2)紧急事故关机功能(EPO),当地震或火灾等紧急事故发生时,可通过面板EPO按键或利用远程遥控EPO功能快速将UPS关机,减少UPS供电系统在紧急事故中造成的损失,有效地保护负载。

(3)整流器采用软启动设计,当UPS的输入电源转为由发电机连续供电使用时,可使发电机得到平滑过渡连接,避免发电机受到瞬间负载的冲击或过载故障,使得发电机保持正常、安全运行,延长发电机组使用寿命。

(4)具有电池漏液侦测功能,可提早侦测出电池的漏液并进行告警,避免电池漏液引起事故。

(5)并机系统可采用共用电池方案,每个电池组由29只电池串联,如在同样给用户提供1h后备时间的情况下,可减少电池的投资,还可以节省大量的安装空间,提高电池的利用效率,当其中一台UPS退出并联系统后,仍能保证满载情况下后备时间为1h,确保信号系统的安全运行,保障高速铁路行车的安全性。

(6)NT系列UPS具有安全、适用的短路保护功能,当侦测到逆变器的输出电压小于50V达两个周期(即40ms)时,便认为输出端短路,逆变器保护锁机,转由旁路供电,转换时间<1ms。在并机系统中,当侦测到UPS逆变器输出电压小于50V达两个周期时,便认为是系统输出短路了,这时并联两台UPS立即关闭逆变器进行自我保护,将负载切换到静态旁路下供电。如果短路故障排除了,则UPS自动恢复到正常工作模式。如果短路故障仍然存在,则靠跳脱静态旁路的输入开关来保护。
