Patent ID: 8624146

Claim:
A metal-encapsulated, gas-insulated, combined, polyphase, three-phase switch disconnector and earthing switch, comprising: a housing; a contact bolt per phase of the switch, wherein each contact bolt is configured to move along a longitudinal axis, and in a first position, connects two active parts of the switch to one another, and in a second position, is connected to a fixed earthing contact piece; and a drive motor that actuates the contact bolts via a drive spindle; wherein lines of movement of the contact bolts of all phases lie in one plane, and each contact bolt is driven by one insulating spindle, the insulating spindle being aligned with the line of movement; and wherein the drive spindle lies in the plane of the lines of movement and runs perpendicular to the insulating spindles, each insulating spindle being coupled to the drive spindle via one deflecting gear mechanism, the deflecting gear mechanism for driving the contact bolts being accommodated in the earthing contact pieces.
