The beneficial effect of above-mentioned structure does: be formed with tortuous arc extinguishing passageway between a plurality of arc extinguishing bars piece of this explosion chamber, tortuous arc extinguishing passageway can cut apart into the short electric arc of multistage with direct current electric arc, thereby be favorable to extinguishing fast of electric arc, and separate and be provided with two arc separation pieces that extend in arc extinguishing passageway both sides on the arc cover, thereby electric arc and two area of contact who separates the arc piece have been increased, be favorable to the quick cooling of electric arc, electric arc can extinguish fast, be favorable to improving the arc extinguishing effect of this explosion chamber, thereby this explosion chamber is applicable to on alternating current circuit breaker and the direct current circuit breaker, and this explosion chamber has compact structure, stable performance is reliable, the effectual advantage of arc extinguishing.
Particularly, two arc baffles are respectively provided with a clamping groove, the two sides of the arc shield are respectively provided with a clamping hook matched with the clamping grooves, and the clamping hooks are clamped in the clamping grooves and form clamping matching of the two arc baffles and the arc shield. The two arc isolating plates and the arc isolating cover are connected in a clamping matching mode, so that the two arc isolating plates and the arc isolating cover are convenient to assemble, and the assembly efficiency of the arc extinguishing chamber is improved.
Particularly, the lower end of the arc-isolating cover is provided with a supporting sheet which is clamped on the static contact, one end of the supporting sheet is provided with a limiting groove, and the limiting groove is clamped on a limiting block of the static contact and forms limiting matching of the supporting sheet and the static contact. The supporting sheet of the arc-isolating cover is connected with the static contact in a limiting and matching mode, so that the arc-extinguishing chamber and the static contact are convenient to assemble, and the arc-extinguishing chamber is more convenient to install.
