OFFSET BUS CONNECTION WITH FIELD SHAPING AND HEAT SINK

摘要

Method and apparatus for reducing the minimum clearance needed between an electrical conductor and ground in switchgear and similar electrical isolation equipment provide a bus-connector having an extended toroidal shape that is designed to allow the size of the switchgear cabinet to be reduced while complying with industry-standard performance requirements. The toroidal shaped bus-connector has mostly or only smooth and rounded surfaces so there are no hard or sharp edges or corners from which electrical discharge from/to ground or other conductors may occur. The shaped bus-connector also has an elongated body that produces an offset connection resembling a “Z,” which allows power buses and breaker terminals that do not vertically line up to connect.

主权项

1. A shaped bus-connector, comprising:
a generally cylindrical head having an exterior wall extending along a length of the head and an interior wall extending a distance into the head, the interior wall defining an opening in the head coaxial therewith at an end thereof; and an elongated body protruding perpendicularly from the generally cylindrical head at the end thereof having the opening therein; wherein the generally cylindrical head has a shape resembling an extended toroid such that corners and edges on the head through which electrical discharge may occur have a radius of curvature.
