摘　　要：对工厂供电保护系统中的无时限电流速断保护进行灵敏度校验时 ,往往很难达到电气设计规范的要求。对其原因进行分析 ,寻求简捷途径与方法。The electric design specification requirement is rarely achieved when the sensitivity of quick break protection without time limiting current is checked in plant power supply system In this paper, the method and approach are searched so the fall of protective quick activity is avoided The practice has proved that this method is rational and practical

关 键 词：无时限电流速断保护 灵敏度 校验 供电保护系统
