12~40.5kV switch cabinets and looped network cabinets of are the largest number of primary substation devices. In recent years,there were many accidents of these devices,which cause negative social influence including economic loss and casualties.Based on comprehensive examination,it is found that the accident potential and inherent defects are mainly concentrated on connection mode,internal arc release ability,internal insulation,overheating,and error-locking preventing.The number of accidents greatly is reduced and the reliability of power system operation is improved significantly through specific countermeasures.
