Claims

[Scope of utility model registration request]

A fixed contact part and a movable contact part are disposed in a container filled with an arc-extinguishing gas so as to be able to come into contact with and be separated from the other, and a puff piston and a puff cylinder are provided in the movable contact part when shutting off. By compressing the puffer chamber, the arc-extinguishing gas is compressed and guided to the nozzle section, and the arc generated between the fixed arc contact of the fixed contact section and the movable arc contact of the movable contact section is suppressed. In the puff type gas circuit breaker which extinguishes the arc by blowing the compressed arc extinguishing gas, a communication hole is provided in the hollow part of the hollow drive rod that drives the puff cylinder to communicate the inner and outer diameters,
In addition, a partition member is provided at the end of the communication hole on the side opposite to the nozzle installation side to partition the hollow part of the drive rod, so that the hollow part of the drive rod and the puffer chamber are connected through the communication hole at the beginning of the cutoff operation. to communicate,
In the latter half of the cut-off operation, the hollow part on the nozzle mounting side of the drive rod is configured to communicate with the gas atmosphere of the container through the communication hole, and the partition member is placed in the opposite direction of the drive rod. A puffer type gas circuit breaker, characterized in that the puffer type gas circuit breaker is fixed to the driving rod by a connecting member leading to the nozzle mounting side and a pin provided on the opposite nozzle mounting side of the nozzle mounting end of the puffer piston. .
