Abstract
A circuit breaker includes a compact pole unit with an encapsulated body having ring(s) and conducting terminals that each extend from the encapsulated body. The body includes a vacuum interrupter and a coupler assembly that may be integrated into the pole unit. The coupler assembly includes a contact spring positioned an end of the compact pole unit, as well as a plunger that may be biased by the contact spring. The circuit breaker also includes an actuator positioned at the end of the pole unit that is opposite the coupler assembly. The circuit breaker also may include a second actuator that is will be connected to the contact spring of the coupler assembly via the plunger, and if so the breaker may be operated via either actuator.
Claims18
A circuit breaker, comprising:
- a first actuator;
- a second actuator;
- and
- a compact pole unit comprising:
- an encapsulated body having a first end, a second end, and an outer surface,
- one or more rings extending from the encapsulated body on the outer surface,
- a first conducting terminal extending from the encapsulated body,
- a second conducting terminal extending from the encapsulated body,
- a vacuum interrupter positioned within the encapsulated body, the vacuum interrupter comprising:
- a vacuum enclosure;
- a movable first electrode assembly having a first stem slidably extending from the vacuum enclosure and slidably connected to the first conducting terminal;
- a second electrode assembly having a second stem extending from the vacuum enclosure and connected to the second conducting terminal;
- and
- a drive rod interconnecting the first actuator to the first stem at the first end of the compact pole unit;
- and
- a coupler assembly comprising:
- a contact spring positioned at the second end of the compact pole unit, and
- a plunger interconnecting the second actuator to the contact spring.
