摘　　要：介绍了微机母线保护的发展过程,举例阐述了西门子7SS60集中式及7SS52分布式微机母线保护系统的保护原理,以及电流互感器饱和判据、结构及功能,并做了大量分析、论证及比较,指出现阶段集中式母线保护装置仍然是母线保护发展的主流,分布式母线保护系统更能适应综合自动化的要求,是将来发展的必然趋势。The development of microcomputer-based bus protection is reviewed. As examples, the theory of bus protection, the criterion for current transformer saturation, the block diagram and function of bus protection for Siemens 7SS60 and 7SS52 microcomputer-based bus protection devices are presented. It is pointed out that the central microcomputer-based bus protection is the mainstream for power systems in China today, and the distributed microcomputer-based bus protection is the trend in the future since it suits better the automation of Chinese power systems.
