摘　　要：通过对海外某华龙一号(HPR1000)厂用电接线方式和电源切换设计理念的介绍,分析了厂用电装置的切换和合闸的原理,并以核电站某次试验失败后事故工况下电源切换为例,对电源切换过程进行分析和验证,说明了核电厂事故工况下电源切换装置能可靠动作的原理,可对后续的核电机组调试提供借鉴。Through the introduction of the factory power wiring mode and power switching design concept of an overseas HPR1000,the principle of switching and closing of the factory power device is analyzed.Taking the power switching under accident conditions after a test failure of nuclear power plant as an example,the power switching process is analyzed and verified,and the principle that the power switching device can act reliably under accident conditions of nuclear power plant is explained,which provides reference for the subsequent commissioning of nuclear power units.
