Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
128 words
A high amperage electrical switching apparatus adapted for use in a corrosive atmosphere comprising: a. a housing; b. resiliently mounted, spaced apart first and second electrical terminals extending from said housing, with each of said terminals having a passageway extending therethrough through which cooling media passes; c. electrical conducting means positioned within said housing electrically communicating with said first and second terminals, with said conducting means being provided with fluid cooling means; and d. electrical circuit breaking means capable of being in an open or closed position electrically communicating with said electrical conducting means, with said circuit breaking means being provided with fluid cooling means, whereby when said circuit breaking means is in a closed position electrical current is capable of flowing between said first and second terminals.
Claim 2
Dependent Claim
128 words
A high amperage electrical switching apparatus adapted for use in a corrosive atmosphere comprising: a. a housing; b. resiliently mounted, spaced apart first and second electrical terminals extending from said housing, with each of said terminals having a passageway extending therethrough through which cooling media passes; c. electrical conducting means positioned within said housing electrically communicating with said first and second terminals, with said conducting means being provided with fluid cooling means; and d. electrical circuit breaking means capable of being in an open or closed position electrically communicating with said electrical conducting means, with said circuit breaking means being provided with fluid cooling means, whereby when said circuit breaking means is in a closed position electrical current is capable of flowing between said first and second terminals.
Claim 3
Dependent Claim
50 words
The apparatus of claim 1 wherein said housing is generally in the form of a hollow rectangular structure comprising a pair of vertical side walls, top and bottom walls communicating with said side walls, and a pair of spaced apart end walls communicating with the side walls and end walls.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1 wherein said housing is provided with a means of maintaining the atmospheric pressure therein at least slightly in excess of ambient pressure to prevent corrosive vapors from entering said housing.
Claim 5
Dependent Claim
85 words
The apparatus of claim 1 wherein each of said electrical terminals comprises: a. a lug adapted to engage a conductor, said lug having a hollow passageway therein directing cooling fluid therethrough, and b. a plurality of flexible, hollow conduits each having a passageway therein directing cooling fluid therethrough and a means for conducting electrical current, with said conduits being in electrical contact with said lug and said passageways communicating with the passageway in said lug, whereby cooling fluid is caused to pass through said terminal.
Claim 6
Dependent Claim
26 words
The apparatus of claim 1 wherein said electrical conducting means comprises a plurality of bus bar members having affixed thereto means for carrying fluid cooling media.
Claim 7
Dependent Claim
23 words
The apparatus of claim 5 wherein said bus bar members affixed to the surface thereof metallic tubing which carries said fluid cooling media.
Claim 8
Dependent Claim
84 words
The apparatus of claim 1 wherein said circuit breaking means includes at least one electrical switching member which comprises: a. a pair of spaced apart contact members having passageways therein for fluid cooling; and b. an interconnecting link member which is adapted to be moved into a position such that it bridges at least part of the space between said contact members which when brought in contact with said contact members provides a path for electrical current to be conducted through said contact members.
Claim 9
Dependent Claim
28 words
The apparatus of claim 7 wherein a plurality Of electrical switching members are provided with said switching members being connected in parallel and positioned in a side-by-side relationship.
Claim 10
Dependent Claim
29 words
The apparatus of claim 7 wherein a plurality of electrical switching members are provided with said switching members being electrially connected in parallel and positioned in vertically stacked relationship.
Claim 11
Dependent Claim
34 words
The apparatus of claim 7 wherein said contact members consist of first and second conduit members, with each of said first and second conduit members haing a passageway therein for conducting cooling fluid therethrough.
