AP1000核电站主泵的电气系统分析

AP1000核电站在提高安全系数的基础上,充分利用大量的非能动技术,取消了应急柴油发电机等核级能动设备,减少了操作员的干预动作,降低了人因因素的影响。使用尽可能少的系统和设备,使得布置简化;采用了维修周期更长甚至免检修的先进设备,减少系统及设备之间的接口,提高了核电厂自身应对各种严重事故或自然灾害的安全响应能力。其中主泵系统由于它的重要性和特殊性,也是技术引进的重点项目;文章通过对主泵的作用和电气系统原理分析,阐述了电气设备的配置及特殊结构。

Analysis of the RCP Electrical System of AP1000 Nuclear Power Plant

AP1000 is the 3rd generation nuclear power plant imported from Westinghouse.It takes full advantage of passive techniques on the basis of safety coefficient enhancement,and it cancels the nuclear-grade active devices such as emergency diesel generator,decreases the operations by operators,and therefore decreases the human factor influences.It uses the minimum systems and equipment.and therefore simplifies the configuration.It adopts the advanced equipment that with long maintenance cycle or maintenance free,it decreases the interfaces of systems and equipment,enhances the safety response ability of the power plant to serious accidents or natural disasters.The RCP system is a key item for importing this technology due to its importance and particularity.It＇s to understand the configuration and special structure of the electric equipment by analyzing the function of RCP and the principle of electric system.
