Abstract: A circuit breaker using an arc contact with a resistor is provided to prevent damage of an insulating gas between the arc contacts by reducing arc energy, thereby preventing deterioration of insulating performance. A cylinder(600) is filled with an arc extinguishing gas inside. A main fixed contact(620) is formed inside the cylinder. A main movable contact(630) forms a first current path by being connected to the main fixed contact and is separated from the main fixed contact to interrupt a fault current. A fixed arc contact(640) is formed inside the cylinder and includes a resistor(646) inserted between a body(642) and a tip(644) to reduce the fault current. A movable arc contact(650) forms a second current path by being connected to the fixed arc contact and is separated from the fixed arc contact after being in contact with the resistor of the fixed arc contact to reduce the fault current.

Abstract: A hybrid type gas interrupter using an arc contact point having a compression cylinder is provided to improve an interruption performance of a small electric current by dualizing the interruption performance based on amplitude of the current. An operator, which provides power for driving a driving unit of a gas interrupter with power, is installed on the position to change an installation position from a conventional movable arc contact point to a fixed arc contact point. The conventional fixed arc contact point is a movable arc contact point(604). A compression cylinder(613), which compresses a gas to raise a pressure for interrupting a small electric current, is installed on the inside of the movable arc contact point(604). A conventional movable arc contact point becomes a fixed arc contact point(607) corresponding to a change from the conventional fixed arc contact point to the movable arc contact point(604). A second heat expansion room(612) as a space for expanding a gas by an arc generated from a separation of the movable arc contact point(604) and the fixed arc contact point is installed on a rear end of the fixed arc contact point(607).
