上海人民电器介绍塑壳断路器和小型断路器的区别

2020/8/19 11:21:22点击:

塑壳断路器和小型断路器的区别有哪些方面?主要是以下几点不同:

1、塑壳断路器能接入较粗导线,如35平方以上的。小型断路器只适合接10平方以下的导线。

2、塑壳断路器端头用螺母联接,容易压紧,接触良好。小型断路器采用较小的压紧端子,且只能用螺丝刀拧紧,力矩不够,不容易压紧,接触不太好。
3、塑壳断路器对过流和短路采用两套装置分别保护,过流保护动作值可以人工调整。小型断路器对过流和短路共用一套装置,电流不可调。
4、塑壳断路器相间距离大,且有灭弧罩,灭弧能力强,能承受更大的短路电流,还不易引发相间短路。寿命也长。
5、小型断路器动作灵敏度比塑壳断路器高。
