MEDIUM VOLTAGE ELECTRIC DISTRIBUTION CELL

摘要

The present invention relates to a medium-voltage electric distribution cubicle designed to be fitted between two parts of an electric circuit so as to perform at least the functions respectively of current flow between the parts, of current interruption between the parts, of circuit disconnection, and of earthing. This cubicle is characterized in that it comprises a switch (or circuit breaker) with vacuum break technology also performing the disconnecting switch function and, in series with said switch (circuit breaker), a selector with at least two positions, respectively a current flow position and an earthing position of one of the parts of the circuit.
