Abstract
The utility model discloses arc-extinguishing grating sheets arranged in a step shape. The single arc-extinguishing grating sheet is of a rectangular sheet structure, and an asymmetrical groove is processed in the middle of the lower edge of the single arc-extinguishing grating sheet. In order to facilitate quicker entrance of electric arcs into an arc extinguishing chamber, elongation of the electric arcs and increase of arc resistance, two or more arc-extinguishing grating sheets are arranged in the arc extinguishing chamber positively and negatively in an interlacing manner. In order to increase the cooling area of the arc-extinguishing grating sheets to the electric arcs and achieve the advantages of small size and high breaking capacity, the arc-extinguishing grating sheets are as long as possible, and the bottoms of the arc-extinguishing grating sheets are arranged in a step shape along the slope of an arc striking sheet in order to avoid the contact with the arc striking sheet. The arc-extinguishing grating sheets provided by the utility model can be used for effectively lengthening the electric arcs so as to increase the short circuit breaking capacity of a circuit breaker and effectively enhance the arc-extinguishing capacity of the circuit breaker.
Description
Technical field
The utility model relates to the arc extinguishing grid pieces of stepped arrangement.
Background technology
In low-tension switch electric appliance, when producing electric arc between contact, electric arc is drawn into arc extinguishing grid pieces under the convergent force effect of the magnetic line of force, thereby a long arc is separated into the multistage short arc, plays the effect of electric arc cooling, thereby reaches arc quenching effect.Traditional arc extinguishing grid pieces breaking capacity is lower, can not carry out arc extinguishing fast and effectively.
Summary of the invention
In view of this, the utility model provides the arc extinguishing grid pieces of the good stepped arrangement of a kind of arc quenching effect, can under the prerequisite that does not increase former arc control device volume, improve arc extinction performance, realizes high breaking.Ancillary equipment is the striking sheet.
Single arc extinguishing grid pieces is rectangular laminated structure; The centre position of its lower limb is processed with asymmetric groove; Groove is made up of two sections breach, and first section breach is the rectangle that lateral symmetry is arranged, second section breach is set at the top of first section breach; Second section breach is the trapezoidal of vertical asymmetric layout, and its afterbody is semicircle.The top of each arc extinguishing grid pieces upper groove is at sustained height, and the length of groove is 1/3 of adjacent arc extinguishing grid pieces length with the striking sheet, and wherein the length of first section breach is that the length of 3/5, the second section breach of groove length is 2/5 of groove length.Wherein between second section breach and the first section breach by the circular arc smooth transition, between first section breach and the arc extinguishing grid pieces base by the circular arc smooth transition.
Two or more arc extinguishing grid pieces are the wrong installation of a positive reciprocal cross in arc control device, and promptly the bossing of bottom portion of groove and sunk part stagger each other.
Arc extinguishing grid pieces helps extinguish arcs to the cooling of electric arc, is not influencing arc motion and can not cause the length that increases arc extinguishing grid pieces under the prerequisite of arc extinguishing grid pieces short circuit as far as possible.Therefore contact with the striking sheet for fear of the arc extinguishing grid pieces bottom, with the bottom design of the grid sheet array of two or more arc extinguishing grid pieces compositions for being uneven in length, along the stepped arrangement of the gradient of striking sheet.Saidly steppedly can be half staged, full staged or step.
Two side ends of arc extinguishing grid pieces are added with recessed limited step, can realize the qualification to the arc extinguishing grid pieces position.
Beneficial effect
The arc extinguishing grid pieces stepped arrangement in bottom can increase the film-cooled heat of grid sheet to electric arc, realizes small size, high breaking, thus effectively elongate electric arc, increase arc quenching effect.Adopt arc extinguishing grid pieces simultaneously with asymmetric groove, and arc extinguishing grid pieces wrong installation of a positive reciprocal cross in arc control device, help electric arc and get into arc control device faster and elongate electric arc, increase arc resistance.Adopt the arc extinguishing grid pieces of this structure can effectively improve the short circuit breaking capacity of circuit breaker.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, single arc extinguishing grid pieces 1 is a rectangle sheet structure, and processing has asymmetric groove in the middle of arc extinguishing grid pieces 1 lower end.Said groove is made up of two sections breach, first section rectangle that breach 2 is arranged for lateral symmetry, and it is the trapezoidal of vertical asymmetric layout that 3, the second sections breach of second section breach 3 are set at the top of first section breach 2, its afterbody is semicircle.The top of each arc extinguishing grid pieces upper groove is at sustained height, and the length of groove is and 1/3 of striking sheet adjacent gate leaf length that wherein the length of first section breach 2 is that the length of 3/5, the second section breach 3 of groove length is 2/5 of groove length.Between second section breach 3 and the first section breach 2 by the circular arc smooth transition, between first section breach 2 and arc extinguishing grid pieces 1 base by the circular arc smooth transition.
Two side ends of arc extinguishing grid pieces 1 are processed with recessed limited step respectively, realize the qualification to arc extinguishing grid pieces 1 position.
As shown in Figure 2, arc extinguishing grid pieces is the wrong installation of a positive reciprocal cross in arc control device, the bossing of bottom portion of groove and sunk part is staggered each other, thereby elongate electric arc effectively, increases arc resistance.
In order to increase the film-cooled heat of arc extinguishing grid pieces, improve arc quenching effect, realize small size, high breaking, the length of the grid sheet that extends as far as possible, grid sheet bottom is not in order to contact with the striking sheet, along the stepped arrangement of the gradient of striking sheet.
As shown in Figure 3, be the arc extinguishing grid pieces that half staged is arranged,
As shown in Figure 4, be the arc extinguishing grid pieces of full staged arrangement,
As shown in Figure 5, be the arc extinguishing grid pieces of step arrangement.
In sum, more than being merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
