Problems solved by technology

However, some components, such as high-power contactors, transformers, capacitors, etc., are heavy and / or bulky, and therefore, external carts or convenient support frames must be placed in the cabinet when removing these components from the cabinet. Outside the body near the access plate or door to receive these components
Placing support brackets near access doorways often blocks access to the interior of the cabinet, requiring workers to tilt carts to get closer to parts that need to be moved

Embodiment Construction

[0019] Referring now to the drawings, several specific embodiments of the present invention will be described later in conjunction with the drawings, in which the same reference numerals are always used to refer to the same elements, and various features therein are not necessarily drawn to scale. The present invention provides a safe electrical shut-off and withdrawal device and method for electrical energy conversion system components or equipment that use a combination of a supporting structure and an electrical shut-off device. The device and method are particularly effective when used in related motor drive devices. The device and method will be described in an example medium voltage motor drive system, although other implementations may be related to other types or forms of electrical energy conversion systems These power conversion systems require the use of a single electrical shut-off and support system to shut off the electrical connection of one or more components and...

Abstract

Methods and integrated apparatus are disclosed for electrically disconnecting and allowing external support and access for electrical devices in a power conversion system cabinet. The apparatus includes a support structure that translates a power conversion system component at least partially through a door or other cabinet opening between a first position with the component entirely within the cabinet and a second position with the component supported at least partially outside the cabinet, as well as a power disconnect apparatus operated by translation of the support structure to disconnectthe component from electrical power when the support is translated from the first position to the second position.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Patent Application No. 60 / 862,130, filed October 19, 2006, entitled "Shut-off and Isolation Mechanism for Withdrawable Batteries with Lead-Out Rail Plates," the entirety of which The contents are hereby incorporated by reference. technical field [0003] The present invention relates generally to power conversion, and more particularly to an apparatus and method for safely shutting down and extracting motor drives and other power conversion system components from a cabinet. Background technique [0004] Electrical energy conversion systems are used in medium voltage motor drives, or in applications where electrical energy is converted to drive electric motors or other loads. These systems may include motor drives, starters, power conditioning equipment, etc. These systems are usually installed in cabinets to protect the components of the system from contamination or other...
