It is also more and more wider with scope.
The profile of direct current breaker of plastic casing and AC circuit breaker is without what difference, but it is to differ to be specific to technical performance
Sample, because alternating current is 50Hz sine wave, there are two zero crossings in each cycle, so the breath arc of AC circuit breaker goes out
Arc can extinguish completely in this point, and direct current does not have zero crossing, and direct-current arc caused by disjunction is invariable, and electric current is got over
The big time is longer, and electric arc is just more difficult to extinguish.
The content of the invention
Based on this, it is necessary to provide it is a kind of can be by the direct current breaker of plastic casing of arc extinction.
A kind of direct current breaker of plastic casing, it is characterised in that including breaker body, the body of the circuit breaker is provided with arc extinguishing
Room, the arc-chutes include two side plates and arc extinguishing grid pieces component, and the arc extinguishing grid pieces component is located between two side plates,
The arc extinguishing grid pieces component includes the multiple arc extinguishing grid pieces arranged from top to bottom, and described arc extinguishing grid pieces one end is provided with breach, and institute
The bottom for stating breach is an inclined-plane.
Above-mentioned technical proposal, because arc extinguishing grid pieces one end is provided with breach, and the bottom of breach is an inclined-plane, can reduce electricity
Arc dia, increase its internal ion concentration, strengthen diffusion and cooling effect, electric arc is elongated or barrier is set in internal arctube
Hinder, make local ion and electronics compound, liberation is more than liberation, just can be with strong applicability by arc extinction.
In one of the embodiments, the side plate is provided with multiple connecting holes, and the side plate passes through multiple connections
The arc extinguishing grid pieces component that hole riveting is arranged from top to bottom.
In one of the embodiments, the arc extinguishing grid pieces component includes top arc extinguishing grid pieces, bottom arc extinguishing grid pieces and more
Individual middle part arc extinguishing grid pieces, multiple middle part arc extinguishing grid pieces be located at the top arc extinguishing grid pieces and the bottom arc extinguishing grid pieces it
Between, the top arc extinguishing grid pieces and the bottom arc extinguishing grid pieces are all horizontally disposed arc extinguishing grid pieces, multiple middle part arc extinguishings
Grid all tilts successively and axial symmetry is set successively.
Above-mentioned technical proposal, due to middle part arc extinguishing grid pieces one end all inclination and successively axial symmetry setting successively, one can be entered
Step reduces arc diameter, easily by the arc extinction performance of arc extinction, further raising direct current breaker of plastic casing.
In one of the embodiments, the arc extinguishing grid pieces are respectively provided with least one positioning with the both ends that the side plate is connected
It is raised.
Above-mentioned technical proposal, due to provided with positioning convex, it is possible to achieve the precise positioning of arc extinguishing grid pieces and side plate, installation is more
It is convenient.
In one of the embodiments, the shape of the positioning convex and the form fit of the connecting hole.
Beneficial effect：Above-mentioned direct current breaker of plastic casing, compared with prior art, there is advantages below：
1st, because arc extinguishing grid pieces one end is provided with breach, and the bottom of breach is an inclined-plane, can reduce arc diameter, make it
Internal ion concentration increase, strengthens diffusion and cooling effect, and electric arc is elongated or placed obstacles in internal arctube, make it is local from
Son and electronics are compound, liberation is more than liberation, just can be with strong applicability by arc extinction.
2nd, due to provided with positioning convex, it is possible to achieve the precise positioning of arc extinguishing grid pieces and side plate, installation are more convenient.
