O Utility Model Registration Claims A fixed arc contact, a movable arc contact provided on the outer peripheral surface of the fixed arc contact so as to be slidable in the axial direction, and capable of coming into contact with and separating from the fixed arc contact by sliding, and this movable arc contact. an arc-extinguishing gas supply device that is fixed to the contact and sprays arc-extinguishing gas onto the arc generated by the separation when the movable arc contact separates from the fixed arc contact; and an end of the arc-extinguishing gas supply device. A gas breaker is provided with a nozzle that is fixed to surround the fixed arc contact and guide arc-extinguishing gas to the arc, the nozzle having a plurality of openings that penetrate the nozzle side wall in a radial direction. A gas breaker characterized by being formed with gaps in the axial direction and spaces in the circumferential direction.

Claims

[Scope of utility model registration request]

(1) A fixed arc contact, a movable arc contact that is provided on the outer peripheral surface of the fixed arc contact so as to be slidable in the axial direction, and that can be moved into and out of contact with the fixed arc contact by sliding, and a movable arc contact that is fixed to the movable arc contact. ,
an arc-extinguishing gas supply device that sprays arc-extinguishing gas onto the arc generated by the separation when the movable arc contact separates from the fixed arc contact;
fixed to the end of the arc extinguishing gas supply device so as to surround the fixed arc contact, and guiding the arc extinguishing gas to the arc;
A gas breaker comprising a nozzle, wherein the nozzle has an opening that radially penetrates a nozzle side wall.

(2) The gas breaker according to claim 1, wherein the plurality of openings are provided with a gap in the axial direction and are also spaced apart in the circumferential direction.
