双路供电

对不间断电源使用过程中经常遇到的几个问题，如双路供电、漏电、开关及发电机接入、UPS的并联及冗余等问题进行了简单的探讨。

The paper discusses several problems which are commonly encountered while applying uninterruptable power , such as : parallel power feed , leakage , switch - on or generator switch - on , parallel connection of UPS and redundancy .

借鉴其他核电项目的设计思路，提出了一种新的直流系统设计方案，能够结合核电厂厂用电系统的特点，为DCS提供安全、可靠的双路供电电源。

Learning from the designing methods of other nuclear power projects , a new design for DC power supply system is put forward , which provides a safe and reliable double-circuit power supply for DCS with consideration of the characteristics of the service power system in nuclear power plants .

最后讨论了电子控制装置的抗干扰技术和复式电源双路供电技术。

Finally , the anti-electromagnetic-interference techniques for the electronic control system and the power supply reduplicated techniques were discussed .

双路供电故障转向零位（无零位的开关不作）；

Transfer to zero positon when appears fault in double circuit power supply ( no action if without zero position );

最后，项目研制了交流电源冗余切换装置的样机系统，实现了双路供电的快速准确切换。

Meanwhile , the break-before-switch operating mode of the switches has also greatly raised the reliability . Finally , a prototype system of the AC power redundancy switching device has been developed which realized fast switching between dual power supplies .
