Abstract
A jumper is for an electrical switching apparatus having a plurality of poles. Each of the poles comprises a terminal. The terminal of a first one of the poles is proximate the terminal of a second one of the poles. The jumper includes a jumper member having an attachment portion and a heat sink portion. The attachment portion is structured to electrically connect the terminal of the first one of the poles to the terminal of the second one of the poles. The heat sink portion includes a plurality of spaced apart heat transfer members that are arranged in a plurality of rows and a plurality of columns.
Claims18
A jumper for an electrical switching apparatus, said electrical switching apparatus comprising a plurality of poles, each of said poles comprising a terminal, the terminal of a first one of said poles being proximate the terminal of a second one of said poles, said jumper comprising:
- a jumper member comprising an attachment portion, a heat sink portion, a first side, a second side disposed opposite the first side, a first edge extending from proximate the attachment portion, and a second edge disposed opposite the first edge and extending from proximate the attachment portion, said attachment portion being structured to electrically connect the terminal of the first one of said poles to the terminal of the second one of said poles, said heat sink portion comprising a plurality of spaced apart heat transfer members,
- wherein said plurality of spaced apart heat transfer members are arranged in a plurality of rows and a plurality of columns,
- wherein said plurality of rows and said plurality of columns extend outwardly from the first side between the first edge and the second edge,
- wherein each of said heat transfer members has a width and a height,
- wherein the width is greater than the height,
- wherein said jumper member further comprises a plurality of elongated fins extending outwardly from the second side, and
- wherein each of said elongated fins extends from the first edge to the second edge.
A method of making a jumper comprising:
- extruding a jumper member from a single piece of electrically and thermally conductive material;
- and
- machining the jumper member to form an attachment portion and a heat sink portion comprising a plurality of spaced apart heat transfer members arranged in a plurality of rows and a plurality of columns, each of said heat transfer members having a width and a height,
- wherein said plurality of rows and said plurality of columns extend outwardly from a first side of said jumper member between a first edge of said jumper member and a second edge of said jumper member,
- wherein the width of said heat transfer members is greater than the height,
- wherein said jumper member further comprises a plurality of elongated fins extending outwardly from a second side of said jumper member disposed opposite the first side,
- wherein each of said elongated fins extends from the first edge to the second edge, and
- wherein the first edge and the second edge each extend from proximate the attachment portion.
An electrical switching apparatus comprising:
- a plurality of poles each comprising a terminal, the terminal of a first one of said poles being proximate the terminal of a second one of said poles;
- and
- at least one jumper comprising:
- a jumper member comprising an attachment portion, a heat sink portion, a first side, a second side disposed opposite the first side, a first edge extending from proximate the attachment portion, and a second edge disposed opposite the first edge and extending from proximate the attachment portion, said attachment portion electrically connecting the terminal of the first one of said poles to the terminal of the second one of said poles, said heat sink portion comprising a plurality of spaced apart heat transfer members,
- wherein said plurality of spaced apart heat transfer members are arranged in a plurality of rows and a plurality of columns,
- wherein said plurality of rows and said plurality of columns extend outwardly from the first side between the first edge and the second edge,
- wherein each of said heat transfer members has a width and a height,
- wherein the width is greater than the height,
- wherein said jumper member further comprises a plurality of elongated fins extending outwardly from the second side, and
- wherein each of said elongated fins extends from the first edge to the second edge.
