Filed:

Sep 17, 2002

Appl. No.:

10/244426

Inventors:

Edward M. Lobo - Seymour CT

Assignee:

Parallax Power Components LLC - Bridgeport CT

International Classification:

H01G 4015

US Classification:

361273, 361303

Abstract:

A segmented metallized film having a dielectric film, a metallized layer, and at least one fuse disposed within each segment of a plurality of segments along a center margin of the metallized layer. The metallized layer is on a portion of the dielectric film such that the dielectric film has a metallized edge, an unmetallized edge, and an uncoated area between the metallized layer and the unmetallized edge. The center margin is substantially parallel to the machine direction of the film. The center margin is disposed in the metallized layer approximately equidistant to the metallized edge and to the unmetallized edge. The metallized layer has a plurality of transverse margins running from the center margin to the uncoated area. The center margin and the plurality of transverse margins define the plurality of segments.

International Classification:

H01G 900

US Classification:

361534, 361535, 361303, 361305, 361 15, 361272, 361433

Abstract:

A capacitor including an expandable part fabricated on a capacitor housing is enclosed. The expandable part is expandable by a fault that occurs within the capacitor housing, thereby extending the capacitor housing to contact with an external interrupter. The external interrupter includes an external electrode and an external sensing circuit. The external sensing circuit detects a contact between the capacitor housing and the external electrode and sends a signal to disconnect the capacitor from an apparatus circuit.

Assignee:

Aerovox - New Bedford MA

International Classification:

H01G 4/22
H01G 7/00

US Classification:

361315, 3613013, 29 2542

Abstract:

A self protected fluid filled capacitor that includes a capacitor section. Preferably, the capacitor section is configured to attach to a cover that can be placed on a capacitor housing. The capacitor contains an insulating fluid that surrounds the capacitor section when the capacitor section is inserted in the capacitor. A capacitor chamber that is configured to contain a retained portion of the insulating fluid and the capacitor section is also included. Also contained in the capacitor is an overflow chamber region in communication with the capacitor chamber. The capacitor chamber is configured to provide a capacitor chamber opening near a top portion, through which excess fluid contained in the capacitor chamber can flow. The overflow chamber region communicates with the capacitor chamber opening to receive excess insulating fluid, thereby providing a fluid volume margin to assure that the capacitor section is completely covered.

Appl. No.:

12/893696

Inventors:

Edward M. Lobo - North Dartmouth MA, US
Paul Winsor, IV - Somerset MA, US

International Classification:

H01G 4/32

US Classification:

3613015

Abstract:

A rolled film capacitor includes a first dielectric layer of high crystallinity polypropylene and a first metalized electrode stack adjacent to and contacting the first dielectric layer. The first metalized electrode stack includes a first substrate located between first and second metallic films. The capacitor also includes a second dielectric layer of high crystallinity polypropylene, and a second metalized electrode stack adjacent to and contacting the second dielectric layer, the second metalized electrode stack comprising a second substrate located between third and fourth metallic films.

International Classification:

H01G 422
H01G 1300

US Classification:

361315

Abstract:

A zinc metallized film capacitor includes a dielectric fluid comprising epoxidized soybean oil having at least one epoxy group per molecule, preferably four epoxy groups per molecule. Utilizing epoxidized soybean oil with zinc metallization results in a substantial performance improvement under high temperature and high voltage conditions, providing a zinc metallized film capacitor of reduced size and cost. In addition, the epoxidized soybean oil is relatively non-toxic, reducing environmental concerns.

Appl. No.:

8/498643

Assignee:

Magnetek, Inc. - Los Angeles CA

International Classification:

B65D 8586

US Classification:

428 369

Abstract:

A plastic tube and a method and apparatus for forming it in which a strip of relatively thin plastic sheet material is cut from a roll of the material and wound around a mandrel. Overlapping ends of the strip are sealed to form the tube. The edge of the strip is inwardly bent to form an inwardly extending lip. When used in the manufacture of a capacitor, the tube is placed in a can on top of the disc of insulating material and a capacitor roll is placed in the tube. The edge of the sheet material can be pre-creased so that when folded inwardly, darts of the material form the lip.

Abstract:

A metallized film capacitor includes an aromatic ester dielectric fluid including 2. 0-5. 0% by weight of an epoxide in an aromatic ester such as dioctyl phthalate. Utilizing such a particular amount of epoxide results in a substantial performance improvement under high temperature and voltage conditions, providing a metallized film capacitor of reduced size and cost.
