摘要
近年来,中低压开关柜的使用范围越来越广,在这个过程中,确保它的安全稳定运行是至关重要的。基于此,本文首先将阐述弧光产生的机理与电弧的危害,然后分析故障保护的原理与系统构成,最后使用实际的工程案例说明弧光保护在中低压开关柜保护过程中的应用价值。
In recent years,have been widely used.medium and low voltage switchgears are.In this process,it is very important to ensure its safe and stable operation.Based on this,this paper first elaborates the mechanism of arc generation and the harm of arc,then analyzes the principle and system composition of fault protection,and finally illustrates the application value of arc protection in the protection process of medium and low voltage switchgear with practical engineering cases.
