style="font-size: 16px;">是电力系统发展的一个产物，适用于电力系统中各个电压等级。对于低压的微机保护装置，接入的电压为400V，而对于高压的微机?；ぷ爸?，接入的电为100V。不同的微机?；ぷ爸?，在硬件和软件上都会有差别。不过在原理上都是大同小异，那么微机保护装置有什么特点？</span></p><p style="text-align:center"><img

16px;">2.由于微机保护采用各种电力逻辑运算来实现?；すδ?所以只需要采集线路上的电流电压,这样大大简化了接线</span></p><p><span style="font-size: 16px;">3.微机保护的?；こ隹?、?？爻隹凇⒕偷乜刂瞥隹诙际峭ü蛔榧痰缙鞫鞯?所以非?？煽?/span></p><p><span style="font-size:
