Multi-pole breaker assembly

A method for operating distribution systems for primary stations incorporating at least one multi-pole breaker assembly, comprising, for each pole, a breaker having an insulating feedthrough developing along a main direction constituting the median axis of said breaker, the median axes of the breakers of said multi-pole breaker assembly being substantially parallel among them, said breakers being integral to one another and apt to be moved with respect to respective input and output external contacts to operate the line connection and disconnection, said external input and output contacts comprising a set of bus bars substantially parallel among them, said method comprising the steps of:

• arranging said breakers thereby the external terminals thereof being arranged onto a rectilinear pathway, substantially parallel to the median axes of said breakers, intersecting the respective input and output external contacts, said median axes being substantially vertical and substantially lying onto a median vertical plane perpendicular to said bus bars;
• to operate the disconnection, moving said breakers thereby the respective external terminals thereof moving along said pathway from a position of electrical connection until placing themselves at a predetermined disconnection distance;
• and
• to operate the connection, moving said breakers thereby the respective external terminals thereof moving along said pathway from said predetermined disconnection distance to carry out an electrical connection.
