Abstract
A kind of arc-suppressing method, arc-extinguishing mechanism is made up of plastic module, blowout coil, arc extinguishing cover and pedestal, and described plastic module is arranged on pedestal, and primary and secondary contact is embedded on plastic module; Described arc extinguishing cover is arranged on plastic module, the arc quenching plate that metal material is made is set in arc-extinguish chamber, described blowout coil is enclosed in the plastic module under fixed contact, and this is auspicious not only increases insulation property, and rapid heat dissipation, when contact produces electric arc time, under the magnetic fields that blowout coil produces, electric arc elongates by the effect of electromagnetic force, is blown into by the arc-extinguish chamber that arc quenching plate is formed, contact with arc quenching plate, electric arc is cooled and extinguish.
Description
Technical field
The present invention relates to a kind of electric elements, the arc-extinguishing mechanism specifically in a kind of electromagnetic contactor.
Background technology,
Blowout coil in common contactor is not closed, such setting and easily generating heat, and power consumption is large, although people have done many improvement, but the problem of the unavoidable arc quenching effect difference of main contacts, this not only directly affects the useful life of contactor, but also can cause the malfunction of contactor.
Summary of the invention
In order to make up the above-mentioned deficiency of contactor arc-extinguishing mechanism, the invention provides a kind of arc-extinguishing mechanism, blowout coil is enclosed in the plastic module under fixed contact by this mechanism, in so avoiding the possibility of being burnt by arc flower, and accelerate heat radiation, make it reach good arc quenching effect.
The present invention solves the technical measures that its technical problem takes, arc-extinguishing mechanism is made up of plastic module, blowout coil, arc extinguishing cover and pedestal, described plastic module is made square, plastic module is arranged on pedestal, binding post is fixed on the both sides of plastic module, primary and secondary contact is embedded on plastic module, and connects binding post, described arc extinguishing cover is arranged on plastic module, and described arc extinguishing cover is arranged on plastic module, by primary and secondary contact cover in arc-extinguish chamber, arranges the arc quenching plate that metal material is made in arc-extinguish chamber, and the joint of arc quenching plate is arranged on the lower end of arc extinguishing cover, is characterized in, blowout coil is enclosed in the plastic module under fixed contact, the joint of blowout coil connects the joint of arc quenching plate in arc-extinguish chamber, described arc quenching plate adopts the arc arc quenching plate structure of question mark shape shape on the cross section perpendicular with blowout coil length direction, arc quenching plate is that these auspicious insulation property that not only increase of shape are reduced in transition gradually from upper end arc quenching plate to the joint of lower end arc quenching plate on the cross section perpendicular with blowout coil length direction, and rapid heat dissipation, during use, when contact produces electric arc time, under the magnetic fields that blowout coil produces, electric arc elongates by the effect of electromagnetic force, be blown into by the arc-extinguish chamber that arc quenching plate is formed, contact with arc quenching plate, electric arc is cooled and extinguish, thus reach the object of good arc extinguishing.
Further, described blowout coil is made up of iron core, insulating case, coil and joint, and at iron core external insulating sleeve, coil is around on insulating case.
The invention has the beneficial effects as follows, blowout coil rapid heat dissipation, arc quenching effect is good, compact conformation.
