Abstract:
A power station switch having high nominal current, the switch comprising:a break chamber mounted inside a protective and electrically conductive sheath, said break chamber containing a dielectric gas under pressure put into continuous circulation, and a radiator/heat-exchanger situated outside said sheath and connected to said break chamber to cause said dielectric gas to circulate and to cool said dielectric gas, wherein the break chamber has a bottom metal case at its lower end enabling the dielectric gas cooled in the radiator/heat-exchanger to pass towards the low end of said break chamber, said bottom metal case being grounded and being in electrical contact with said protective and electrically conductive sheath, and wherein said break chamber has at its top end a top metal case connected to said radiator/heat-exchanger via a hollow insulator.
