MEDIUM VOLTAGE ELECTRIC DISTRIBUTION CELL

摘要

The invention relates to a medium voltage electric distribution cell to be placed between two portions of an electric circuit so as to provide at least the functions of enabling the current flow between the portions, interrupting the current between the portions, cutting off the current, and grounding, respectively. The cell is characterised in that it comprises a switch (or circuit breaker) (1) of the vacuum cut-off technology, which can also be used as a selector and, in series with said switch (circuit breaker) (1), as a selector (2) with at least two positions, i.e. a current flow position and a position for grounding one of the circuit portions, respectively.
