A compartment module for a metal-enclosed, modular medium-voltage distribution system has an essentially box-type construction and includes a first set of mutually opposite completely closed walls, a second set of mutually opposite walls having identical large openings bounded by a narrow flange, and a third set of mutually opposite walls having small openings bounded by a wide flange. When assembled, a number of the modules can be arranged to face one another with similar walls and the remaining openings closed off by a cover. The modules can be mechanically coupled to each other by bolt joints or clamp joints in order to obtain a mechanical and electromagnetic seal. A method of manufacturing a module from sheet metal, and a method of manufacturing a medium-voltage distribution system from standard modules includes using isolators and busbar systems.

Compartment module and distribution system assembled therewith

Metal-encased modular medium-voltage distribution system with one or more sections constructed of compartmental modules having components of the distribution system and each section having at least one first busbar system for internal section connection including n phases, each of the phases extending substantially rectilinearly in a first direction (x). At least one second busbar system with n phases for external connection to other sections, each of the phases of the second busbar system extending essentially rectilinearly in a second direction (y) substantially perpendicular to the first direction (x). First switching elements extending in a third direction (z) substantially perpendicular to both the first direction (x) and the second direction (y), and being arranged between the phases of the first busbar system and corresponding external conductors; and second switching means extending substantially in the third direction (z), and arranged between the phases of the first busbar system and corresponding phases of the second busbar system.
