Abstract
A kind of arc-chutes of breaker.Mainly solve the problems, such as that existing arc-chutes arc extinction performance is poor.It is characterized by: being equipped with elongated striking slot in the middle part of the arc striking piece.When the advantage is that the electric arc generated when dynamic/static contact disjunction by the striking of striking slot, wherein the striking slot of minister's shape separates electric arc, since the electric arc of striking slot two sides moves in the same direction, so that electric arc attracts each other, it is entered in striking slot slot to which electric arc can attract each other again, it avoids electric arc from separating to two sides, greatly improves arc extinction performance, while improving the service life of two sides arc side wall.
Description
Technical field
The utility model relates to breaker technical fields, more particularly to a kind of arc-chutes of breaker.
Background technique
Arc-chutes generally include that arc side wall, arc extinguishing grid pieces group, arc striking piece, go out flame piece, arc-extinguish chamber, are the weights on breaker
Want component part, setting, can direct shadow for limiting arc space position and accelerating the device of arc extinction in proximate contacts
Ring the short-circuit capability of breaker.
But the effect is unsatisfactory for existing arc-chutes striking, when the electric arc edge of moving contact and static contact disjunction generation is drawn
When arcs striking, electric arc can be separated to two sides, cause arc extinction performance weak, and easily cause the carbonization of arc sidewall surfaces, be hindered
Arc motion largely effects on arc extinction performance.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides a kind of arc-chutes of breaker, solves existing arc extinguishing
The problem of room arc extinction performance difference.
Technical solution adopted by the utility model: a kind of arc-chutes of breaker, including arc-extinguish chamber, two arc sides
Wall, one group of arc extinguishing grid pieces, arc striking piece, arc quenching plate；The arc-extinguish chamber is mounted on one end of two arc side walls, the arc extinguishing grid pieces
It is mounted between two arc side walls with arc striking piece；Elongated striking slot is equipped in the middle part of the arc striking piece.
Corresponding offer on the side of arc-extinguish chamber one end decompresses hole to the arc extinguishing grid pieces with arc striking piece.
The material of the arc side wall uses red steel cardboard.
The end of the arc extinguishing grid pieces is equipped with the notch in " V " type, the slot of the end of the arc striking piece towards arc extinguishing grid pieces
The bending of mouth position, the striking slot position is in the bending part of arc striking piece end.
Bumps staggeredly constitute maze-type structure at the notch of adjacent arc extinguishing grid pieces.
The arc quenching plate is equipped with three groups, and is arranged in parallel in arc-extinguish chamber by flash barrier, the arc quenching plate and arc-chutes
Several through-holes uniformly to gather are equipped on end face.
The beneficial effects of the utility model are: using above scheme, the electric arc that when dynamic/static contact disjunction generates is by striking
When slot striking, wherein the striking slot of minister's shape separates electric arc, since the electric arc of striking slot two sides moves in the same direction, so that electric arc phase
Mutually attract, entered in striking slot slot so that electric arc can attract each other again, avoids electric arc from separating to two sides, greatly improve arc-extinguishing
Can, while improving the service life of two sides arc side wall.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment arc-chutes.
Fig. 2 is the structural schematic diagram of another angle of the utility model embodiment arc-chutes.
Fig. 3 is the cross-sectional view of the utility model embodiment arc-chutes.
Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
A kind of arc-chutes of breaker, including 2, one groups of the arc side wall of arc-extinguish chamber 1, two arc extinguishing grid pieces 3, arc striking piece 4, go out
Arcs 5；The arc-extinguish chamber 1 is mounted on one end of two arc side walls 2, the arc extinguishing grid pieces 3 and arc striking piece 4 be mounted on two every
Between arc side wall 2；The end of the arc extinguishing grid pieces 3 is equipped with the notch 31 in " V " type, and the end of the arc striking piece 4 is towards arc extinguishing
31 position of notch of grid 3 is bent, and the arc quenching plate 5 is equipped with three groups, and is arranged in parallel in arc-extinguish chamber 1 by flash barrier 7, institute
It states and is equipped with several through-holes uniformly to gather on arc quenching plate 5 and arc-chutes end face.
Wherein, bumps staggeredly constitute maze-type structure at the notch 31 of adjacent arc extinguishing grid pieces 3, using mazy knot
Structure had not only been able to achieve high breaking capacity but also energy fast arc extinction.
Elongated striking slot 41 is equipped in the middle part of the arc striking piece 4, the striking slot 41 is located at the bending part of 4 end of arc striking piece
Position.
When the electric arc generated when dynamic/static contact disjunction passes through 41 striking of striking slot, wherein the striking slot 41 of minister's shape is by electric arc
Separate, since the electric arc of 41 two sides of striking slot moves in the same direction, so that electric arc attracts each other, electric arc can attract each other to enter again to be drawn
In 41 slot of arc slot, avoids electric arc from separating to two sides, to greatly improve arc extinction performance, while improving the use of two sides arc side wall
Service life.
Further, the arc extinguishing grid pieces 3 with arc striking piece 4 is corresponding on the side of 1 one end of arc-extinguish chamber offers decompression
Hole 6, pressure when electric arc is generated are discharged from decompression hole 6, are more advantageous to arc motion, improve arc extinction performance.
In addition, the material of the arc side wall 2 uses red steel cardboard, more existing DMC insulating materials, red steel cardboard are compared
So that arc sidewall surfaces will not be carbonized and generate cooling gas, dielectric strength and resume speed in arc-chutes are further increased.
Embodiment is not construed as the limitation to utility model, but any spiritual improvements introduced based on the utility model,
It should all be within the protection scope of the utility model.
