| 摘 要： | 单台UPS为DCS控制系统供电,故障发生率高,电池向外部供电时间短,不能满足生产的需要,而且一旦UPS停止供电,给系统和工艺生产带来了不必要的损失。采用两台UPS串联供电连接,主/副UPS可以自动切换,延长了供电时间,减少了生产损失,给工厂带来了效益。

| Abstract: | A single UPS power supply to the DCS control system has a high failure rate and the time of battery to the external power supply is short.Thus it is unable to meet the needs of production.Once UPS stops,it would bring unnecessary losses to the system and production process.If the power supply adopts two serial UPS,the main/auxiliary UPS can automatically switch,prolong the time of power supply,reduce production loss,and bring benefits to a plant. |
