Abstract
Provided is a vacuum circuit breaker that can increase structural stability and reduce required space by reducing the distance from a pressure vessel to a driving unit. A vacuum circuit breaker includes: a pressure vessel that is filled with insulating gas at a predetermined pressure; a vacuum interrupter disposed inside the pressure vessel and having a fixed electrode and a movable electrode within a vacuum tube in a vacuum state; and a spring module that has one side connected to an end of the movable electrode through an insulating link, moves through the pressure vessel while maintaining airtightness to transmit driving force of a driving unit to the movable electrode, and is equipped with a spring that applies contact pressure to the movable electrode when closing the contacts.
Claims7
A vacuum circuit breaker comprising:
- a pressure vessel filled with an insulating gas of a predetermined pressure;
- a vacuum interrupter disposed in an internal space of the pressure vessel, and having a fixed electrode and a movable electrode in a vacuum tube having a vacuum state;
- and
- a spring module having one side connected to an end portion of the movable electrode via an insulating link, and having a spring applying contact pressure to the movable electrode when the movable electrode is input, wherein the spring module penetrates through and moving in the pressure vessel while maintaining airtightness to transmit driving force of a driving unit to the movable electrode.
