摘要
介绍了双母联双分段母线保护配置方式,分析了双母联双分段母线系统保护接线原理,尤其是死区保护及分段断路器失灵保护的动作原理和逻辑,以及分段电流互感器接入母线保护的极性问题。
The protection configuration of 4-section busbar system was introduced and the protection connection principle was analyzed. The action principle and logic of dead-zone and CB failure protection were emphasized and the polarity of section current transformer connecting busbar protection was discussed.
