US Patent:

7206188, Apr 17, 2007

Filed:

Mar 8, 2005

Appl. No.:

11/073751

Inventors:

Edward M. Lobo - Dartmouth MA, US
Leonid Zayaruzny - New Bedford MA, US

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.

Appl. No.:

6/280924

Donald F. Hunter - Wareham MA

International Classification:

H01G 700
H01G 114

US Classification:

29 2542

Abstract:

Electrical terminals for a wound capacitor section and a method of attaching the electrical terminals to the section are disclosed. Adjacent convolutions of a wound capacitor section are electrically connected to one another through conventional metal spraying techniques. Flat copper tabs having the surfaces thereof tinned, as with a thin layer of solder, provide the terminal connection leads for use of the capacitor in an electrical circuit. The tinned copper tabs are secured to either end of the capacitor section by tack welding the tab to the sprayed metal end of the winding. Tack welding of the tab to the metal coating insures electrical connection but provides little strength in mechanical connection. Each end of the capacitor section is then again provided with a sprayed metal coating over both the first coating and the tinned tabs.

International Classification:

H01G 422

US Classification:

361318

Abstract:

A dielectric composition containing a major amount of a bis (C. sub. 6-12 alkyl) phthalate such as diisononyl phthalate, a minor amount of butylated monochloro diphenyl oxide, and a small effective amount of an epoxy stabilizer, and an electrical device such as a capacitor comprising metal foil electrodes separated by paper sheet and/or plastic film impregnated with said composition.

International Classification:

H01G 2/18
H01G 2/10

Abstract:

A capacitor is provided with a case having a receptacle with an expandable section that allows the receptacle to extend axially when internal pressure builds within the case as a result of a fault. Terminals are mounted on the cover and electrically connected to the electrodes of a capacitor element through an interrupter plate, via leads. The plate is attached to the section of the case that extends under pressure, whereby the plate is drawn away from the cover, thereby breaking the electrical connections to the terminal. The plate may also work in conjunction with a cover that expands outward in response to internal pressure, to provide a second pressure interrupter mechanism.
