International ClassH02B 001/56Foreign Application Priority Data1995-10-26 FRAbstractA medium-voltage substation includes at least two insulative material chambers each provided with at least one opening for the gas-tight passage of a set of three-phase busbars. Each chamber contains a three-position three-phase switch for connecting the busbars to first gas-tight electrical feed-throughs and for connecting the first feed-throughs to second gas-tight feed-throughs connected to ground. The first feed-throughs of at least one chamber are each electrically connected to a single-phase cable. The first feed-throughs of each chamber are electrically connected either to a fuse or to a pole of a circuit-breaker disposed in an insulative material compartment. | |
