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.
