Abstract

A three position medium voltage fluid insulated compact operating and cut-off apparatus, comprising a set of three poles in which each pole is provided with a fixed contact and a moving contact, the moving contact being positioned on a pivoted arm which is rotatable between a first closed position in engagement with the fixed contact, a second cut-off position and a third position of connection to earth, in which each moving and fixed contact of the set of three poles is positioned on three insulating supporting elements which in turn are fixed to supporting braces, and each of the arms carrying the moving contacts is of the telescopic type, and carries its associated moving contacts by means of an insulated lever connected to an operating bar, a cylindrical element pumping the fluid to the fixed contact being provided within the rotatable arm, and at least one metal draining element being additionally positioned on each of the insulating supporting elements between the portion carrying the fixed contact and the remaining portion of the supporting element. <IMAGE>
