Abstract

The transformer has a disconnection system with a fuse, a disconnecting switch, a short circuit and a micro-fuse. The disconnecting switch, short circuit and the micro-fuse are placed in a water tight dielectric liquid retention container (86) that is placed in the transformer. The disconnecting switch is placed downstream of the fuse and short-circuit.
