Single bottle interrupter
A bi-stable mechanism for a vacuum interrupter. The bi-stable mechanism includes an actuator; and a cam pivotable by the actuator, the cam moving a moveable contact. Wherein a bellows assembly is positioned above a vacuum bottle and coupled to a housing. The bellows assembly includes an outer cylindrical shell surrounding an opening spring, a spring plate, a contact spring, and a bellows. The bellows assembly reciprocates the moveable contact to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.
1. A bi-stable mechanism for a vacuum interrupter, the bi-stable mechanism comprising:
an actuator; and
a cam pivotable by the actuator, the cam moving a moveable contact;
wherein a bellows assembly is positioned above a vacuum bottle and coupled to a housing, the bellows assembly including an outer cylindrical shell surrounding an opening spring, a spring plate, a contact spring, and a bellows, the bellows assembly reciprocating the moveable contact to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.
2. The bi-stable mechanism of claim 1 , wherein the vacuum interrupter interrupts a voltage of at least approximately 69 kV.
3. The bi-stable mechanism of claim 1 , wherein the housing is comprised of a polymer epoxy.
4. The bi-stable mechanism of claim 1 , wherein current flows through the contacts in the closed position.
5. The bi-stable mechanism of claim 1 , wherein a flow of current through the contacts is stopped when the contacts are apart from each other.
6. The bi-stable mechanism of claim 1 , wherein the actuator is a conductive operating arm.
7. The bi-stable mechanism of claim 1 , wherein the actuator includes a pair of bumpers.
8. The bi-stable mechanism of claim 1 , wherein the cam is a pair of pivotably connected links.
9. A bellows assembly positioned above a vacuum bottle and coupled to a housing of a vacuum interrupter, the bellows assembly comprising:
an outer cylindrical shell surrounding an opening spring;
a spring plate;
a contact spring; and
a bellows;
wherein the bellows assembly reciprocates a moveable contact to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.
10. The bellows assembly of claim 9 , wherein the vacuum interrupter interrupts a voltage of at least approximately 69 kV.
11. The bellows assembly of claim 9 , wherein the housing is comprised of a polymer epoxy.
12. The bellows assembly of claim 9 , wherein current flows through the contacts in the closed position.
13. The bellows assembly of claim 9 , wherein a flow of current through the contacts is stopped when the contacts are apart from each other.
