Abstract
A system for providing selective capacitance with a bundled capacitor is described herein. The bundled capacitor can include a housing a cap, a central common terminal, a plurality of auxiliary terminals, an interrupter, an insulating spider, a plurality of individual rolled sandwich like connected capacitors, a thermal fuse, a frangible electrical connection, an insulating layer, a resin, and an expansion chamber. A single phase motor can be connected to the bundled capacitor.
Claims20
A system for providing selective capacitance with a bundled capacitor, the system comprising:
- a. a bundled capacitor comprising:
- (i) a housing comprising:
- 1. a body with an interior and an exterior;
- 2. a first integral end connected to the body;
- and
- 3. a hermetically sealable deformable cap connected to the body opposite the first integral end, wherein the cap comprises an expandable body and a lip integral with the expandable body for non-removable engagement with the body;
- (ii) a central common terminal disposed through the cap;
- (iii) a plurality of auxiliary terminals concentrically disposed around the central common terminal;
- (iv) an interrupter disposed on the expandable body and extending toward the body of the housing, wherein the interrupter engages each of the auxiliary terminals and the central common terminal;
- (v) an insulating spider disposed on the cap comprising:
- 1. a tubular section with a central annulus for containing the central common terminal;
- and
- 2. at least three legs extending from the tubular section for separating the plurality of auxiliary terminals;
- (vi) a plurality of individual rolled sandwich like connected capacitors disposed within the housing, wherein each individual rolled sandwich like connected capacitor comprises:
- 1. an individual capacitance value;
- 2. a positive terminal in electrical communication with one of the plurality of auxiliary terminals;
- and
- 3. a negative terminal, wherein the negative terminals are electrically connected together to form an insulated collective connection;
- (vii) at least one thermal fuse disposed within the housing, wherein the at least one thermal fuse is in electrical communication with the insulated collective connection and with the central common terminal;
- (viii) an insulating layer substantially disposed on the interior of the body;
- (ix) an insulating and flame retarding curing resin disposed around the plurality of individual rolled sandwich like connected capacitors for rigidly supporting and connecting the plurality of individual rolled sandwich like connected capacitors to the first integral end and at least partially to the insulating layer;
- and
- (x) an expansion chamber formed between the insulating and flame retardant curing resin and the interrupter, wherein the expansion chamber enables the cap to deform when at least one of the individual rolled sandwich like connected capacitors overheats in the bundled capacitor;
- and
- b. at least one motor in electrical communication with the bundled capacitor.
