摘要:
A puffer-type gas circuit-breaker having improved interruption performance and dielectric performance, comprising: a partition wall provided in a stationary cylinder on the moving side of the circuit-breaker to form an intra-stationary cylinder space, a mechanical puffer chamber provided adjacent to one flange of the partition wall and a hot gas exhaust chamber provided on the same side as another flange of the partition wall, wherein the stationary cylinder has gas inlet holes communicated with the intra-stationary cylinder space and formed on one side relative to a virtual plane that bisects the stationary cylinder in a radial direction, gas outlet holes communicated with the intra-stationary cylinder space, and hot gas exhaust openings communicated with the hot gas exhaust chamber, further communicated with the puffer shaft flow hole after an arc is generated and formed in radial directions of the stationary cylinder and on the other side relative to the virtual plane.
