Dix ans d'union monétaire : une rétrospective

The hybrid circuit breaker has at least two series-connected arcing chambers, which are operated by a commmon drive via a transmission (29) connected upstream from it. It is intended to be possible to assemble this transmission (29) easily in the interior of the hybrid circuit breaker. This is achieved in that the transmission (29) is formed from at least two transmission parts which can be plugged together, with a first transmission part being firmly connected to the at least one first arcing chamber and a second transmission part being firmly connected to the at least one second arcing chamber. The transmission (29) also has means which allow the movements of the at least two arcing chambers to be technically suitably matched to one another and to be optimized with respect to the time sequence and switching speed thereof.
