EPOXY MOLD INSULATED MULTI SWITCH AND SWITCHGEAR FOR UNDERGROUND POWER LINE

摘要

An epoxy mold insulated multi switch and a switchgear for a underground power line is provided to reduce failure rate by installing a vacuum interrupter in a switchgear after molding the circumstance of the vacuum interrupter with silicon. A switchgear includes a vacuum interrupter(20), a bus-bar, a shield, and a sensor. The part body of the switchgear is composed of the bus-bar, the shield, and the sensor excluding the vacuum interrupter. The circumstance of some part of the switchgear is molded with epoxy, and the circumstance of the vacuum interrupter is molded with silicon. The vacuum is assembled into the switchgear as press-fit type. Air outlets(14,14') are formed inside the switchgear.
