Claims

[Claims for Utility Model Registration] 1. A breaker container consisting of an insulating cylinder and a cylindrical body that keeps an insulating arc-extinguishing gas airtight is placed in an earth potential container filled with an insulating gas, and at least A breaker unit having an arc-extinguishing gas spraying device consisting of a pair of fixed and movable contacts, a buffer cylinder and a buffer piston is housed, and the arc-extinguishing gas generated by the blowing device is movable with the fixed contact during the breaker operation. In a grounded tank type gas breaker that extinguishes the arc by blowing between the contacts, the cylindrical body is
A grounded tank type gas breaker, characterized in that an airflow control member is provided to control the gas flow discharged from the breaker. 2. The grounded tank type gas breaker according to claim 1, wherein the airflow control member is supported and fixed between the insulating cylinder and the cylindrical body. 3. The grounded tank type gas breaker according to claim 1, wherein the airflow control member is integrally formed with the cylindrical body. 4. The inside diameter of the cylindrical body is larger than the inside diameter of the insulating cylinder, and a different diameter part is provided between the insulating cylinder and the cylindrical body, and the airflow control body is formed by this different diameter part. Section 1,
The grounded gas breaker according to paragraphs 2 and 3. 5. The grounded tank type gas breaker according to claim 1, wherein the airflow control member is fixed inside the cylindrical body. 6. The grounded tank-type gas breaker according to claim 1, wherein the airflow control member also serves as a current-carrying conductor.
