摘　　要：近年来我国很多工程存在过度使用双电源末端切换装置的情况,其使用量远远高于国外发达国家同类工程,很多设计人员将所有二级负荷供电设备的末端配电措施均采用双电源末端切换,实际上应该按负荷性质区分对待。《民用建筑电气设计标准》GB 51348-2019第13.7.4标准解决的主要问题就是末端配电箱的位置何处合理的问题。这一点也在新版《建筑设计防火规范》GB 50016-2014(征求意见稿)中体现。In recent years,there has been excessive use of dual power end switching devices in many projects in China,which is much higher than similar projects in foreign developed countries.Many designers adopt dual power end switching for the end distribution measures of all secondary load power supply equipment,which should be treated differently according to the nature of load.The main problem solved by the standard in article 13.7.4 of“Electrical Design Standard for Civil Buildings”(GB 51348-2019)is where the location of terminal distribution box is reasonable.This is also reflected in the new version of“code for fire protection design of buildings”GB 50016-2014(draft for comments).

关 键 词：二级负荷 双电源末端切换 人员密集场所
