Arc-chutes convenient, stable and reliable for performance.
To achieve the above object, the utility model uses a kind of arc-chutes, including shell, multiple parallel intervals to be arranged in shell
Internal arc extinguishing grid pieces, the shell include the second flash barrier that the first flash barrier and the first flash barrier fasten, shell
It is respectively arranged with step on the both ends of top plate, mounting hole is provided on step, one end in shell is provided with arc striking piece, described
Being constituted between first flash barrier, the second flash barrier and arc striking piece has spark chamber, each arc extinguishing grid pieces to be separately positioned on arc extinguishing
Intracavitary corresponds to parallel interval at the top of each arc extinguishing grid pieces in first flash barrier and is provided with multiple clamping pieces, described
Be formed between multiple clamping pieces it is multiple lead arc channel, be respectively arranged on the top plate of the shell and respectively lead arc channel and be connected
Logical waist-shaped hole corresponds in second flash barrier and is respectively arranged with buckling groove at each clamping piece, and the one of the clamping piece
End is fastened in buckling groove and constitutes the clamping engagement of the first flash barrier and the second flash barrier.
The advantageous effect of above structure is：It is provided at both ends with the step to match with the pedestal of breaker in shell, favorably
Gap between the shell and pedestal for reducing the arc-chutes, and mounting hole is provided on step, it ensure that arc-chutes and pedestal
Connection it is more compact, and the clamping piece in shell can play positioning action, can avoid the first flash barrier and filled with the second flash barrier
Dislocation offset occurs for timing, is conducive to the efficiency of assembling for improving the arc-chutes, and leading arc channel and can will go out between each clamping piece
The indoor residual arc export of arc, is conducive to the arc quenching effect for improving the arc-chutes, to which the arc-chutes have simple in structure, knot
The advantage that structure is compact, assembly is convenient, stable and reliable for performance.
Particularly, it is respectively arranged with limited step on the both sides of the shell.It is provided with and breaks on the both sides of shell
The matched limited step of pedestal of road device, avoids the gap between arc-chutes and pedestal excessive, ensure that arc-chutes and pedestal
Connection it is more compact.
Particularly, first flash barrier is towards being provided with strip-shaped clamp groove on the side of the second flash barrier, and described the
It is corresponded on two flash barriers and is provided with matched clamping raised line at strip-shaped clamp groove, clamping raised line is fastened in strip-shaped clamp groove and constitutes
The clamping engagement of first flash barrier and the second flash barrier.First flash barrier is connected with the second flash barrier by the way of being engaged by clamping
It connects, is convenient for the assembling of the first flash barrier and the second flash barrier, improves the efficiency of assembling of the arc-chutes.

Specific implementation mode
As shown in Figures 1 to 3, the utility model embodiment is a kind of arc-chutes, including the setting of shell 10, multiple parallel intervals
Arc extinguishing grid pieces 20 in shell 10, the shell 10 includes the first flash barrier 11, fasten with the first flash barrier 11 the
Two flash barriers 12 are respectively arranged with step 101 on the both ends of the top plate of shell 10, mounting hole 102, shell are provided on step 101
One end in body 10 is provided with arc striking piece 13, is constituted between first flash barrier 11, the second flash barrier 12 and arc striking piece 13
There are spark chamber 100, each arc extinguishing grid pieces 20 to be separately positioned in spark chamber 100, it is corresponding in first flash barrier 11
Parallel interval is provided with multiple clamping pieces 111 at the top of each arc extinguishing grid pieces 20, is formed between multiple clamping pieces 111
It is multiple to lead arc channel 112, it is respectively arranged on the top plate of the shell 10 and the waist-shaped hole respectively leading arc channel 112 and be connected
