Modular skid frame

Abstract

A modular skid frame and device to reduce the potential for harm and injury from arc flashes. The modular skid frame comprises a plurality of frame members secured together to form the skid frame, and one or more hook members formed on one or more of the frame members to permit the receipt of a bucket or blade from a loader, scoop tram or other construction or mining equipment into the bowl portion and behind the bill portion of the hook member to facilitate the lifting and moving of the skid frame. Also disclosed is a device for racking a circuit breaker into and out of a circuit breaker cradle. The device comprises an actuator operatively connected to the circuit breaker cradle to permit the circuit breaker to be racked into and out of the cradle without direct or indirect contact on the part of an operator.

Description

FIELD OF THE INVENTION[0001]This invention relates generally to modular skid frames of the type that may be used to house electrical components such as switch gear, transformers, motor controls, load centers, fused and un-fused disconnects, breakers, electrical bus and the like. In another aspect the invention relates generally to the field of reducing arc flash hazards.BACKGROUND OF THE INVENTION[0002]Skid frames for housing electrical components have been used in the mining, exploration, oil and gas, and construction industries, and in general industry, for a considerable length of time. Typically, such skid frames include one or more of a variety of different electrical components that perform various functions as may be required at a particular application.[0003]Skid frames as described above are generally constructed in a robust fashion from high strength material, such as steel, a steel alloy or a composite, in order to withstand the relatively harsh environments in which they...

AI Technical Summary

Benefits of technology

[0007]The invention therefore provides a new and improved modular skid frame that provides for the potential for an increased effective operating life through utilization of a novel mechanism to permit the skid frame to be lifted and moved through the use of front end loaders, scoop trams and the like without causing significant damage to the skid frame. The invention also provides for a new and novel mechanism to permit the joining of adjacent modular skid frames, of the same or different configuration, while accommodating shear loading between them. In the further embodiment the in

Problems solved by technology

In numerous applications skid frames containing load centers, fused disconnects, breakers and similar components are situation within potentially dangerous environments where there may be the presence of explosive or ignitable gases or dust particles.

Under conditions of this nature the potential for an arc flash that can occur during the operation of electrical equipment is of significant concern.

Typically, arc flashes occur during the operation of electrical equipment, such as drawing out or closing a circuit breaker, opening or closing an electrical device, or as a result of an insulation failure on electrical wires or system
