Abstract: The switchgear applied in the field of electric power equipment to ensure stable electricity supply is developing towards the direction of medium-voltage, miniaturization, maintenance free and high-reliability. Introduction was made to several key technologies of realizing switchgear miniaturization, maintenance free and high-reliability, such as solid insulated technology, epoxy resin casting technology, operation mechanism technology and so on. By means of key technologies comparison applied in switchgear at home and abroad, this paper pointed out the shortage of domestic switchgear technology and its development direction.
Key words: switchgear; medium-voltage; miniaturization; solid insulation
