In recent years

fires caused by emerging electrical equipment occur frequently

and the fire suppression process is relatively complex and difficult. This paper summarizes the structural characteristics and fire initiation mechanisms of such equipment

compares the applicable scenarios of fine water mist

perfluorohexanone

heptafluoropropane

and combined fire suppression systems

and analyzes the practical effectiveness of monitoring methods such as residual current detection

arc fault detection

gas sensors

and AI early warning platforms. In addition

improvement suggestions are proposed regarding wire and cable selection

fire stopping

and fire protection equipment layout. The relevant conclusions can provide references for fire suppression system design and revision of fire protection standards.
