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.
Claims20
A capacitor, comprising:
- a housing configured to extend from a first position to a second position when a fault occurs within the capacitor,
- wherein in the first position, the housing is not in contact with a sensing surface of an external interrupting circuit,
- wherein in the second position, the housing comes into contact with the sensing surface of the external interrupting circuit.
A capacitor, comprising:
- a housing comprising a first end and a second end;
- and
- an expandable part located on the housing between the first end and second end, the expandable part expands when a fault occurs within the capacitor,
- wherein the housing does not come into contact with a sensing surface of an external interrupting circuit during normal operation of the capacitor,
- wherein the housing comes into contact with the sensing surface of the external interrupting circuit when the fault occurs.
A safety control device for an electrical component, comprising:
- a capacitor, comprising;
- a housing, wherein the housing is configured to include an expandable part that is located on the housing between a first end of the housing and a second end of the housing;
- and
- an external interrupter electrically coupled to the housing, wherein the external interrupter includes a sensing surface and a triggering element, the sensing surface is located at a position close to but not in contact with the housing when the capacitor operates normally, the triggering element is electrically coupled with a power source that provides electrical power to the capacitor,
- wherein when a fault occurs within the capacitor, the expandable part expands such that the housing comes into contact with the sensing surface of the external interrupter, resulting in the triggering element to send a signal to the power source to cut off power to the capacitor.
