Abstract
Power condenser comprising stacks (1) of condensers with their armatures connected with external terminals, housed in a box (2), wherein strips (3) which are hood conductors of heat and have widths approximately equal to the height of a condenser stack (1), are bent so as to surround at least one half of the circumference of one or several condenser stacks (1), the two unbent ends of the strips (3) being in contact with two opposing walls of the box (2). The condenser is applicable particularly to low voltages.
Claims8
A power condenser assembly comprising:
- (a) a metal housing having at least two walls,
- (b) a plurality of capacitor rolls, and
- (c) a plurality of heat conducting sheets, said sheets extending in one direction along substantially the entire length of said rolls, and bent so that each sheet is in contact with at least one-half of the circumference of at least one of said plurality of capacitor rolls so as to form a concave surfaces containing said at least one roll, each sheet having two substantially straight end portions resiliently contacting said at least two walls of said metal housing, said sheets bent in a shape corresponding to one of (1) a double C, one placed above the other, (2) an S, and (3) a double S, whereby said rolls are secured by said sheets.
A power condenser assembly as recited in claim 1, 2 or 10, wherein said sheets are bent in the shape of a double C, one placed above the other.
A method of manufacturing a power condenser having condenser rolls and comprising the steps of:
- (a) bending strips of heat-conducting sheet metal so as to have at least two bent cylindrical surfaces forming at least two concave parts for each strip;
- (b) gripping condenser rolls in the concave parts of the bent strips;
- (c) compressing the assembled strips and the capacitor rolls;
- and
- (d) inserting the compressed and assembled strips and rolls between two opposite walls of a metal box so that the bent strips remain compressed and reliliently pushed into close contact with about half the surface of each roll and with the two opposite walls of the metal box.
