摘　　要：介绍了无母线压变对配套机电设施的影响,分析了上海虹桥国际机场T1航站楼改造工程中10/0.4 kV变电所等效母线电压转换设计方案,可以仅利用进线PT,在不必另外新增母线PT的情况下,获取母线的当前电压。The influence of voltage variation without busbar on supporting mechanical and electrical facilities was introduced.Combining by Shanghai Hongqiao International Airport T1 Terminal rennovation project,the design scheme of equivalent busbar voltage conversion of 10/0.4 kV substation is analyzed.In the scheme,the current voltage of the bus can be obtained by using only the incoming line PT without the addition of the bus PT.

关 键 词：单母线分断 压变 PT柜 电压转换
