MULTI-POLE CIRCUIT BREAKER ASSEMBLY,METHOD FOR OPERATING THIS SYSTEM, AND MEDIUM VOLTAGE DISTRIBUTION SYSTEM FOR THE PRIMARY STATIONS

摘要

A multi-pole breaker assembly (1) and a method for operating distribution systems (51) for primary stations that include said assemblies (1) allow to arrange metallic bays (2) for said assemblies (1) with reduced transversal dimensions, thus realising modular and compact distribution system (51), suitable for transportable solutions, said multi-pole breaker assembly (1) comprising breakers (4a, 4b, 4c) having a respective insulating feedthrough (29) developing along the median axis (A, B, C) thereof, wherein said breakers (4a, 4b, 4c) are arranged thereby the external terminals (30, 31) thereof being arranged onto a rectilinear pathway substantially parallel to the median axis (A, B, C) of said breakers (4a, 4b, 4c), and comprising means for translating (44) said breakers (4a, 4b, 4c) according to a direction having a main component substantially parallel to said median axes (A, B, C) to carry out and remove said line disconnection.
