- the first arc-extinguishing chamber 2 and the second arc-extinguishing chamber 3 have a contact (not shown) inside, and by opening this contact, the electrical arc at a substation or a switching station Cut off current.
- the circuit breaker 50 is a two-point breaker having two arc extinguishing chambers 2 and 3. When each contact is opened inside each arc-extinguishing chamber 2, 3, arc-extinguishing gas is blown toward the contact so that the arc generated at the contact is extinguished.
- the first arc extinguishing chamber 2 and the second arc extinguishing chamber 3 are each connected to a connection conductor 4.
- the first arc extinguishing chamber 2 is disposed on the side of the connection conductor 4 so that the axis 12 thereof is substantially horizontal (substantially parallel to the installation surface 15).
- the second arc-extinguishing chamber 3 is disposed above the connection conductor 4 so that the axis 13 thereof is substantially vertical (substantially perpendicular to the installation surface 15).
- a conductor 16 extending from the opposite side of the first arc extinguishing chamber 2 to the side connected to the connection conductor 4 is led upward from the sealed tank 1, and is connected to the axis 13 of the second arc extinguishing chamber 3. It extends substantially in parallel.
- a conductor 17 extending from the opposite side of the second arc-extinguishing chamber 3 to the side connected to the connection conductor 4 is led out from the sealed tank 1 toward the first arc-extinguishing chamber 2 side,
- One arc extinguishing chamber 2 extends substantially parallel to the axis 12.
- the operating device 8 is a device for opening and closing the contacts of the arc extinguishing chambers 2 and 3.
- the operating device 8 is connected to the connection conductor 4.
- Each contact point is connected to the operation device 8 via an insulating operation rod 9, and the contact points of the arc extinguishing chambers 2 and 3 can be simultaneously operated by one operation device 8.
- the operating device 8 is disposed below the connection conductor 4, that is, on the opposite side of the second arc extinguishing chamber 3 with the connection conductor 4 interposed therebetween.
- connection conductor 4 As described above, by arranging one of the two arc extinguishing chambers 2 and 3 above the connection conductor 4, it is possible to suppress the circuit breaker 50 from being enlarged in the horizontal direction. Thereby, in an electric station such as a substation or a switching station, it is possible to improve the degree of freedom of arrangement of the circuit breaker 50 and to suppress the manufacturing cost.
- connection conductor 4 By disposing the operation device 8 below the connection conductor 4, it is possible to suppress the breaker 50 from being enlarged in the horizontal direction as compared with the case where the operation device 8 is disposed beside the connection conductor 4. Moreover, since the conductors 16 and 17 led out from the sealed tank 1 are configured not to jump out in the horizontal direction as compared with the circuit breaker 50, it is possible to further suppress the circuit breaker 50 from being enlarged in the horizontal direction. it can.
