Abstract
The switchgear comprises a circuit breaker having an open position for isolating a generator from the network, and a closed position for connecting the generator to the network, together with a disconnector having a fixed pole connected to the generator and a contact connected to the fixed pole and movable relative thereto to occupy, when the circuit breaker is open, a first position connecting the generator to a starter circuit and a second position connecting the generator to ground. The moving contact of the disconnector also possesses a third position in which it forms an equipotential appendix for the fixed pole when the circuit breaker is closed. The moving contact does not carry the steady electric current of the generator, thus making it possible advantageously to reduce its dimensions so that they are capable merely of withstanding transient electrical conditions when in the first and third positions.
