摘　　要：讨论了高速公路中压系统相间电流保护。阐述了相间电流保护的任务、类型和设置方法。提出在高速公路中压系统应采用三段式或两段式定时限过电流保护、瞬时或略带时限的速断保护。The current protection between phases in middle voltage system of highway was discussed.The task,type and setup principle of current protection between phases were expounded.It was proposed that 3-section or 2-section timing over-current protection,instantaneous or a little timing rapidly-breaking protection should be applied in middle voltage system of highway.

关 键 词：高速公路 中压系统 继电保护
