GAS-INSULATED SWITCHGEAR APPARATUS

摘要

A gas-insulated switchgear apparatus, whose particularlity consists of the fact that it comprises: a casing, which accomodates at least a first connection terminal and a second connection terminal; an interruption unit, which is electrically connected to the first terminal and comprises an interruption chamber which accomodates a fixed contact and a movable contact which is operatively controlled by first actuation means; a disconnection unit, which comprises at least one first fixed contact which is electrically connected to the interruption unit, a second fixed contact which is connected to the second terminal, a third fixed contact at ground voltage, and at least one first movable contact which can be coupled to at least one of the fixed contacts, the first movable contact being fixed to second rotating actuation means and rotating rigidly with them, the rotation axis of the second actuation means being substantially perpendicular to the longitudinal axis of the interruption chamber; and in that at least one of the first and second actuation means comprise a motor with position control.
