低压断路器的形式和分类 | 2012-2-15 16:52:00

低压断路器的形式和分类

低压断路器又称自动开关，这种开关电器既能接通、承载以及分断正常电路条件下的电流，也能在规定的非正常(故障)电路条件下接通、承载(一定时间)和分断电流。
低压断路器这一名称是我国在1985年公布低压断路器标准后才得到统一使用的。低压断路器的型式按结构可分为万能式断路器和塑壳式断路器两种；按动作速度可分为一般型和快速型两种。交流快速型断路器，通常称为限流断路器，其分断时间短到足以使短路电流在达到预期峰值前即被分断。如果按用途分类，低压断路器可分为配电断路器、电动机保护用断路器、灭磁断路器和漏电断路器等几种。
