Abstract

An apparatus includes a case having an elliptical cross-section capable of receiving a plurality of capacitive elements. One or more of the capacitive elements provide at least one capacitor having a first capacitor terminal and a second capacitor terminal. The apparatus also includes a cover assembly that includes a deformable cover mountable to the case, and, a common cover terminal having a contact extending from the cover. The cover assembly also includes at least three capacitor cover terminals, each of the at least three capacitor cover terminals having at least one contact extending from the deformable cover. The deformable cover is configured to displace at least one of the at least three capacitor cover terminals upon an operative failure of at least one of the plurality of the capacitive elements. The cover assembly also includes at least four insulation structures. One of the four insulation structures is associated with one of the at least three capacitor cover terminals. The apparatus also includes a first conductor capable of electrically connecting the first capacitor terminal of a capacitor provided by one of the plurality of capacitive elements to one of the at least three capacitor cover terminals and a second conductor capable of electrically connecting the second capacitor terminal of the capacitor provided by one of the plurality of capacitive elements to the common cover terminal.

Claims (34)

1. An apparatus comprising:

a case capable of receiving a plurality of capacitive devices, wherein each of the capacitive devices has a first capacitor terminal and a second capacitor terminal;

a cover assembly comprising:

a deformable cover mountable to the case,

a common cover terminal having a contact extending from the cover,

a plurality of capacitor cover terminals, each of the plurality of capacitor cover terminals having at least one contact extending from the deformable cover, wherein the deformable cover is configured to displace at least one of the plurality of capacitor cover terminals upon an operative failure of at least one of the plurality of the capacitive devices, and

a plurality of insulation structures, wherein one of the plurality of insulation structures is associated with one of the plurality of capacitor cover terminals;

a first conductor capable of electrically connecting the first capacitor terminal of one of the plurality of capacitive devices to one of the plurality of capacitor cover terminals and a second conductor capable of electrically connecting the second capacitor terminal of the one of the plurality of capacitive devices to the common cover terminal; and

a magnetic element positioned within the case between at least one of the plurality of capacitive devices and a wall of the case.

2. The apparatus of claim 1 , wherein the plurality of capacitive devices are each separately wound.

3. The apparatus of claim 1 , wherein a combined capacitance value of the plurality of capacitance devices is greater than about 4.0 microfarads.

a first conductor capable of electrically connecting the first capacitor terminal of one of the plurality of capacitive devices to one of the plurality of capacitor cover terminals and a second conductor capable of electrically connecting the second capacitor terminal of the one of the plurality of capacitive devices to the common cover terminal; and

a magnetic element positioned within the case between at least one of the plurality of capacitive devices and a wall of the case.

12. The apparatus of claim 11 , wherein the plurality of capacitive devices are each separately wound.

13. The apparatus of claim 11 , wherein a capacitance value of one of the plurality of capacitance devices is greater than about 4.0 microfarads.

14. The apparatus of claim 11 , wherein each of the plurality of insulation structures is cup shaped.

15. The apparatus of claim 11 , wherein each of the plurality of insulation structures is colored.

16. The apparatus of claim 11 , wherein at least two of the plurality of insulation structures are differently colored.

17. The apparatus of claim 11 , wherein the magnetic element is positioned between at least one of the plurality of capacitive devices and a bottom wall of the case.

18. The apparatus of claim 11 , wherein the magnetic element is positioned between at least one of the plurality of capacitive devices and a side wall of the case.
