Abstract

A capacitor provides a plurality of selectable capacitance values, by selective connection of six capacitor sections of a capacitive element each having a capacitance value. The capacitor sections are provided in a plurality of wound cylindrical capacitive elements. Two vertically stacked wound cylindrical capacitance elements may each provide three capacitor sections. There may be six separately wound cylindrical capacitive elements each providing a capacitor section. The capacitor sections have a common element terminal.

Claims (31)

1. An apparatus comprising:

at least four capacitive devices housed in a case, each of the at least four capacitive devices independently providing at least one capacitance value, each of the at least four capacitive devices having a capacitor terminal, wherein a first capacitive device of the at least four capacitive devices has a capacitance value of 2.5 microfarads, second and third capacitive devices of the at least four capacitive devices each have a capacitance value of 5 microfarads, and a fourth capacitive device of the at least four capacitive devices has a capacitance value of 7.5 microfarads;

a cover assembly comprising:

a cover mountable to the case;

at least four capacitor cover terminals, each of the at least four capacitor cover terminals corresponding to one of the at least four capacitive devices;

at least four insulation structures, each of the at least four insulation structures configured to provide insulation for a respective one of the at least four capacitor cover terminals; and

a common cover terminal, wherein the common cover terminal is electrically connected to the at least four capacitive devices; and

at least four conductors, wherein each of the at least four conductors is configured to electrically connect one of the at least four capacitor cover terminals to the corresponding capacitive device; and

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

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

3. The apparatus of claim 1 , wherein each of the at least four insulation structures is cup shaped.

4. The apparatus of claim 1 , wherein each of the at least four insulation structures is colored.

5. The apparatus of claim 1 , wherein at least two of the at least four insulation structures are differently colored.

6. The apparatus of claim 1 , wherein the magnet element is positioned between at least one of the at least four capacitive devices and a bottom wall of the case.

7. The apparatus of claim 1 , wherein the magnet element is positioned between at least one of the at least four capacitive devices and a side wall of the case.

8. The apparatus of claim 1 , wherein the magnet element is a rectangular strip.

9. The apparatus of claim 1 , wherein the magnet element is disk-shaped with a thickness of approximately 4 mm and a diameter of approximately 40 mm.

10. An apparatus suitable for use in an air-conditioning system and configured to provide a plurality of selectable capacitance values, the apparatus comprising:

at least three capacitive devices housed in a case, each of the at least three capacitive devices independently providing at least one capacitance value, each of the at least three capacitive devices having a capacitor terminal, wherein a first capacitive device of the at least three capacitive devices has a capacitance value of 2.5 microfarads, and second and third capacitive devices of the at least three capacitive devices each have a capacitance value of 5 microfarads;

a cover assembly comprising:

a cover mountable to the case;

at least three capacitor cover terminals, each of the at least three capacitor cover terminals corresponding to one of the at least three capacitive devices;

at least three insulation structures, each of the at least three insulation structures configured to provide insulation for a respective one of the at least three capacitor cover terminals; and

a common cover terminal, wherein the common cover terminal is electrically connected to the at least three capacitive devices; and

at least three conductors, wherein each of the at least three conductors is configured to electrically connect one of the at least three capacitor cover terminals to the corresponding capacitive device; and

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

11. The apparatus of claim 10 , wherein the at least three capacitive devices are each separately wound.

12. The apparatus of claim 10 , wherein each of the at least three insulation structures is colored.

13. The apparatus of claim 10 , wherein each of the at least three insulation structures is cup shaped.

14. The apparatus of claim 10 , wherein at least two of the at least three insulation structures are differently colored.

15. The apparatus of claim 10 , wherein the magnet element is positioned between at least one of the at least three capacitive devices and a bottom wall of the case.
