摘　　要：介绍了弧光的一般特性,以及产生弧光的原因和危害.针对国内中低压母线没有快速保护的现状,提出了一种弧光保护系统,实现了母线、开关柜的快速保护,为开关柜、母线和各种变流设备的弧光故障提供全面的保护,将设备的损害和人员安全的威胁降至最低.The general characteristics, the cause and harm of arc-flash are introduced. In view of the fact that there is no fast protection for medium and low voltage bus currently, the arc-flash pro- tection system is proposed, which system realizes the rapid protection for bus and switchgear and can provide overall protection corresponding to the arc-flash faults of bus, switchgear, various kinds of rectifier equipment, greatly reduce the risk of damage to equipment and lose of worker＇ s life.

关 键 词：弧光保护 中低压母线 快速保护
