Document Type and Number:
WIPO Patent Application WO/2022/178962
Kind Code:
A1
Abstract:
A switchgear system (100) and a method of accessing an electrical component (160) carried by a truck (144) are disclosed. The switchgear system includes a switchgear frame (124) having an interior compartment (128) and a front opening (140) and containing therein at least one electrical switchgear component (170). A truck carries an electrical component and is supported for movement on the switchgear frame. A drive mechanism (146) connects the truck and is configured to rack in the truck into an electrically connected position with the at least one electrical switchgear component, rack out the truck from the electrically connected position into an electrically disconnected position, and rotate the truck upward from its disconnected position into a rotated position to allow operator access through the front opening to the at least one electrical component. The problems that the lift-truck may be cumbersome and the extension rails may deflect are solved.
