Embodiment
As shown in Figure 1, and in conjunction with Fig. 2, novel breaker arc extinguishing structure described in the utility model comprises arc control device 1, arc extinguishing board 2, filters overhead guard 3, mounting screw 4, trip bolt 5, steel rivet 15.One group of arc extinguishing board 2 directly inserts among the arc control device 1 by the groove that is uniformly distributed in left arc separating wall 13, right arc separating wall 14 inboards, and easy to assembly, described one group of flash barrier 2 plays the effect of subdividing the arc, extinguish arcs; Two mounting screws 4 are fastened arc control device 1 together with filtering overhead guard 3 via four trip bolts 5, make two mounting screws 4 become the built-in type structure, install, never drop when dismantling, and make circuit breaker easy to assembly, and increase the fail safe of circuit breaker; Because filtering the cover cap 31 of overhead guard 3 is the integral type pressing, there is not the left and right sides, top splicing construction in the whole arc-control device top that covers, guarantees consistency, the reliability of arc-control device assembling.
As shown in Figure 3, and in conjunction with Fig. 2, arc control device 1 cavity that left arc separating wall 13, right arc separating wall 14 rivet together striking sheet 11, striking sheet 12 by steel rivet 15 of serving as reasons.Wherein striking sheet 11, striking sheet 12 are made by permeability magnetic material, and left arc separating wall 13, right arc separating wall 14 are made by high-strength insulating material, the inwall of left arc separating wall 13, right arc separating wall 14 many grooves that vertically distributing, the usefulness of guide-localization during for flash barrier 2 assemblings.
Described arc control device 1: inside has several by the flame sheet 32 that goes out that permeability magnetic material is made, pairing location notch 11a on the left and right arc separating wall 13,14 of the described flame sheet 32 embedding arc control device that go out, and in arc control device 1, evenly distribute.
Described arc control device 1 are than the existing circuit breaker arc-control device, and the part that participates in the riveted joint combination is few, are very easy to the assembling riveted joint.The cooperation location (with striking sheet 11 identical local feature being arranged) by the location notch 11a on the positioning bar 13a on the left arc separating wall 13 and the striking sheet 11 particularly corresponding to right arc separating wall 14, it is moving to have reduced the up and down string of striking sheet 11 in arc control device 1 effectively, thereby make striking sheet 11 thoroughly stop and be positioned at moving contact arc top movable below it and wipe the possibility of bumping, and can keep closely spaced consistency between striking sheet 11 and the moving contact arc top, improve the striking performance.
As shown in Figure 4, and in conjunction with Fig. 1, Fig. 2, filtering overhead guard 3 is the netted flame sheet 32 and the insulating cells 33 of going out of vertically packing into three and being superimposed earlier in the cover cap 31 that high-strength insulating material is made, two horizontal directions, a vertical direction is tied in the rectangular cavity of cover cap 31, another vertical direction is pushed down by the laterally inserted porous flame sheet 34 that goes out---be in draw-in groove 31c that same aspect is symmetrically distributed usefulness everywhere for flame sheet 34 guide-localizations that go out in cover cap 31 inboards, when laterally advancing, the facet 31a of cover cap 31 2 inboards and the flame sheet 34 2 side stages shoulder 34a that goes out bump by playing position-limiting action; Porous is gone out in the flame sheet 35 same laterally inserted cover caps 31, its anchor point is the draw-in groove 31b that is symmetrically distributed in cover cap 31 inboards everywhere of another aspect again.Such fit tool free, convenient and reliable.
Described filtration overhead guard 3 is the filtering type member, and wherein the go out hole of arranging on the flame sheet 35 of porous is a bit larger tham the hole that porous is gone out and arranged on the flame sheet 34, and macropore group and aperture group staggering contraposition.The staggered stack of flame sheet 32 of going out of three-layer network shape.Such structure is constantly turned round the gases at high pressure that produce from the part electric arc of drawing between the arc road that flash barrier 2 is formed and electric arc and is advanced, decomposes filtration, more helps blow-out, cooling, restrains electric arc and scurries outward; Simultaneously, three-layer network shape flame sheet 32, porous flame sheet 34, the porous flame sheet 35 that goes out that goes out that goes out is permeability magnetic material and makes, collaborative one group of flash barrier 2 and striking sheet 11, when producing, electric arc can induce very strong magnetic field, arc transfer can be quickened in magnetic field, shorten the arcing time, the cold airflow that magnetic field causes also can be taken away part electric arc heat, helps arc extinction; On cover cap 31, offer many row's rectangular openings, favourable heat radiation.
In sum, the utility model novel breaker arc extinguishing structure self assembling and easy to assembly, reliable with low-voltage circuit breaker; Have the modular filter device, arc extinguishing is thorough fast, filters, cooling heat dissipation is abundant, improves the low-voltage circuit breaker interrupting performance, when eliminating electric arc and scurrying outward to circuit breaker and personal adverse effect.
