摘  要：運(yùn)行中的電氣設(shè)備，如有故障電弧產(chǎn)生是非常危險(xiǎn)的。故障電弧經(jīng)常伴隨著設(shè)備的嚴(yán)重?fù)p壞、人員受傷，嚴(yán)重時(shí)甚至危及人員生命。為減少或避免電弧發(fā)生時(shí)造成的危害，弧光保護(hù)裝置應(yīng)運(yùn)而生，故障電弧發(fā)生時(shí)通過快速判別，迅速切除故障點(diǎn)電弧，減少故障電弧持續(xù)時(shí)間，可有效降低設(shè)備損壞及人員傷害程度。

Abstract： During the operation of electrical equipment， it is very dangerous to have an arc short-circuit fault. Arc faults often cause serious damage to equipment and serious or even fatal injuries to operators. Therefore， the arc protection device came into being. By quickly judging the arc fault， quickly removing the fault point， and reducing the duration of the arc fault， it can effectively reduce equipment damage and personal injury.

Keywords： 6 kV busbar; arc protection; fault removal; setting calculation; protector
