Abstract
A metal-encapsulated, gas-insulated high-voltage switchgear assembly includes a three-phase encapsulated busbar housing, at least one busbar disposed in the housing, and at least three single-phase-encapsulated circuit breakers disposed horizontally. The assembly further includes a busbar splitting module having at least one three-phase connecting flange configured to connect to the busbar housing and at least three single-phase connecting flanges pointing downward configured to connect to the at least three single-phase-encapsulated circuit breakers and an outgoer splitting module having at least one three-phase flange and at least three single-phase flanges pointing downward and configured to connect the at least three single-phase-encapsulated circuit breakers to a three-phase-encapsulated outgoer housing.
