摘　　要：文章基于两相电流差保护,首先,介绍了不同电源网络的电量关系,然后,分析了故障类型的自适应特点和自适应保护的判断依据,最后,得出了两相电流差和线电压的自适应速断保护的最小保护范围。Based on the two-phase current differential protection, the topic introduced the relationship between the different electricity supply network, and analyzed the failure characteristics of the type of self-adaptive and the judgement basis of self-adaptive protection, and gave the minimum scope of self-adaptive instantaneous protection on the two-phase current and line voltage.

关 键 词：自适应 电流保护 灵敏度 两相电流差
