Explosion type circuit breaker with arc chute

The invention discloses a blasting type circuit breaker with an arc chute, and the circuit breaker comprises an on-off metal disposed on a housing, and a pedestal disposed on the on-off metal. The shell is in threaded connection with the base, the on-off metal is arranged between the shell and the base, and a blasting assembly is arranged between the on-off metal and the base; according to the invention, the V-shaped arc chute is formed, so that an enough space is formed between the gas guide arc surface and the arc chute for gas exchange, and gas conduction is accelerated; the side, located on the on-off metal, of the blasting cavity is arranged to be in an oval opening shape and form a horn opening shape, the oval opening is made to be tightly attached to the edge of the on-off metal, and therefore when blasting is generated, the breaking groove can be rapidly cut off without large impact force. 本发明公开了一种具有灭弧栅的爆破式断路器，包括，安装在所述壳体上的通断金属，以及安装在所述通断金属上的底座；所述壳体与所述底座螺纹连接，所述通断金属设置在所述壳体与所述底座之间，所述通断金属与所述底座之间设有爆破组件；本发明通
