Background technology
In order to adapt to the continuous increase of net capacity, low-voltage distribution and control system mouth benefit are complicated, and low-tension switch electric appliance has been proposed high-performance, miniaturization requirement, and namely when improving basic mechanical design feature, emphasis improves the complex art economic index.Existing circuit breaker is comprised of operating system, arc quenching system, insulation crust, operating grip etc.On insulation crust, corresponding arc quenching system back-end location is provided with the gas outlet, be provided with the arcing passage between gas outlet and arc quenching system, owing in use there being the larger fault current that cut-offs, the electric arc that produces does not extinguish in arc quenching system fully, remaining electric arc is by the arcing passage, overflow in gas outlet from insulation crust, the arcing that Here it is often says.Due to the existence of arcing, easily bring potential safety hazard in the process of using circuit breaker.
In order to eliminate arcing, can add the device that further to eliminate arcing in the arcing passage between arc quenching system and gas outlet, such as cellular arc extinguishing board or multilayer arc extinguishing grid pieces etc. side by side is set in the shell gas outlet, though cellular arc extinguishing board arc quenching effect is good, a large amount of arcings of having avoided overflow, but because its space is little, complex structure, the high-temperature metal Particle Blocking that is easily gone out by air-blowing, there is very big potential safety hazard, multilayer side by side arc extinguishing grid pieces to have increased to a certain extent the body that opens circuit long-pending, and improved manufacturing cost.
The utility model content
In order to overcome deficiency and the defective in background technology, the utility model provides a kind of breaker of plastic casing and the arcing device that goes out, and mainly solves the existing arcing device that goes out and has in use complex structure, processing difficulties, easily stops up and the inefficient problem of the arcing that goes out.
The technical solution of the utility model is: a kind of arcing device that goes out, comprise mount pad, and be provided with in described mount pad and be some arc extinguishing grid pieces of arranging in the gap, described arc extinguishing grid pieces middle part is provided with the up flange of protuberance, described flange axis and the setting of arcing perpendicular direction.
Described flange and arc extinguishing grid pieces are wholely set.
Described arc flange is through described arc extinguishing grid pieces, and two ends are corresponding with mount pad.
Described mount pad is provided with plate or the slot that plugs with Shell of circuit breaker.
Described flange is circular arc.
Described flange is tapered.
A kind of breaker of plastic casing comprises housing, is provided with the arcing device that goes out described above in described housing, and described housing is provided with slot or plate, and described mount pad is provided with housing and plugs plate or the slot that coordinates.
the beneficial effects of the utility model: owing to taking such scheme, breaker of plastic casing of the present utility model and the arcing device that goes out thereof, when the circuit breaker disjunction, produce a large amount of electric arc, first there are arc control device to carry out arc extinguishing one time, again by the arcing device that the goes out arcing that goes out for the second time, prevent from burning contact and electric component, can effectively stop at the protuberance flange of setting up on arc extinguishing grid pieces and mix in arcing because high temperature makes the metallic particles air-blowing of arc extinguishing grid pieces and the contact vaporization arcing device that goes out to go out, effectively prevent phase fault and electrical equipment malfunction, have simple in structure, be difficult for stopping up, the characteristics that the arcing that goes out is effective and safe.
