Claims

[Scope of utility model registration request]

A container filled with a gas having an arc-extinguishing property, a fixed and movable arc contact arranged oppositely in the container, and a fixed and movable main body provided so as to respectively surround the fixed arc contact and the movable arc contact. a contact, an arc travel plate disposed near the fixed earth contact, and a coil circuit section provided between the fixed arc contact and the fixed main contact so as to surround the fixed arc contact; and a magnetic drive coil which is excited by an arc current and has one end connected to the coil circuit section and the other end connected to the arc running plate, and the arc is driven by the rotational force given by the magnetic flux generated from the magnetic drive coil. In a gas breaker that extinguishes an arc by rotating along an arc running plate, a gas guide taper is provided around the inner surface of the fixed main contact and is inclined toward the arc side at an end on the movable main contact side. an annular groove having a section to form a gas circulation path on the outside of the coil electrical circuit section and the magnetic drive coil; A gas breaker characterized by comprising an exhaust hole communicating with a gas circulation path.
