摘　　要：船舶电力系统的过电流选择性保护设计对系统的安全性起着至关重要的作用,但是很多设计人员对其认识还比较片面,存在一些概念误区,致使设计上出现偏差。通过分析几个典型案例,就选择性保护的概念及设计进行梳理,以期对设计人员有所帮助。Over current discrimination protection design played an important role in ship electrical system＇s safety performance. However, some designers didn＇t study it deep enough, there were some confusion in relevant definitions and designs. In order to help designers to have correct understanding of electrical system discrimination protection, this article analyzed some typical cases which had been encountered during design work. These could serve as reference for relevant electrical system design in the future.

关 键 词：完全选择性 部分选择性 能量脱扣 反时限过流保护
