摘　　要：在输变电工程的建设中,电气主接线中旁路母线在国内已经很少采用,但老挝变电站工程中存在较多带旁路母线的接线形式,且与国内常见带旁路母线的接线存在差异,因此保护配置也有不同。笔者参考国内及国际规范,结合正在建设的老挝230 kV Banlak25变电站工程,对比国内常见旁路接线,对两种旁路接线的保护配置进行研究和探讨,以供今后国内外类似接线的工程参考。In the construction of power transmission and transformation projects,transfer busbar in main electrical connection scheme is seldom used in China,but there are many wiring types with transfer busbar in Laos substation projects,and there are differences with the common wiring with transfer busbar in China,so the protection configuration is also different.Referring to the domestic and international norms and combining with Laos230kV Banlak25substation project under construction,the authors compare the common transfer bus configuration in China and study the protection configuration of the two kinds of transfer bus configuration,so as to provide reference for similar wiring projects at home and abroad in the future.
