Abstract
Disclosed is an arc extinguishing method. An arc extinguishing mechanism comprises a plastic module, magnetic blow-out coils, an arc extinguishing cover and a base. The plastic module is mounted on the base, a main contact and an auxiliary contact are inlaid on the plastic module, the arc extinguishing cover is mounted on the plastic module, arc extinguishing plates made of metal materials are arranged in the arc extinguishing cover, and the magnetic blow-out coils are sealed in the plastic module behind the static contacts. Accordingly, the insulating performance is improved, heat is dissipated fast, and when generated by the contacts, electric arcs are drawn under the action of electromagnetic force of a magnetic field generated by the magnetic blow-out coils, are blown into the arc extinguishing cover consisting of the arc extinguishing plates, are in contact with the arc extinguishing plates and are cooled down to be extinguished.
Description
Technical field
The present invention relates to a kind of electric elements, specifically the arc-extinguishing mechanism in a kind of electromagnetic contactor.
Background technology,
Blowout coil in the common contactor does not seal, such setting and easily heating, and power consumption is large, although people have done many improvement, but the problem that the unavoidable arc quenching effect of main contacts is poor, 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 remedy the above-mentioned deficiency of contactor arc-extinguishing mechanism, the invention provides a kind of arc-suppressing method, the method is enclosed in blowout coil in the plastic module under the fixed contact, so not only avoided by the arc flower burn may, and accelerated 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 comprised of plastic module, blowout coil, arc extinguishing cover and pedestal, described plastic module is made square, plastic module is installed on the pedestal, binding post is fixed on the both sides of plastic module, primary and secondary contact is embedded on the plastic module, and connects binding post; Described arc extinguishing cover is installed on the plastic module, described arc extinguishing cover is installed on the plastic module, with primary and secondary contact cover in arc-extinguish chamber, the arc quenching plate that metal material is made is set in arc-extinguish chamber, the joint of arc quenching plate is arranged on the lower end of arc extinguishing cover, and described blowout coil is comprised of iron core, insulating case, coil and joint, at the iron core external insulating sleeve, coil is characterized on insulating case; Blowout coil is enclosed in the plastic module under the fixed contact, the joint of blowout coil connects the joint of arc quenching plate in the arc-extinguish chamber, and this is auspicious not only to have strengthened insulation property, and rapid heat dissipation, during use, when the contact produced electric arc, under the magnetic fields that blowout coil produces, electric arc was subjected to the effect of electromagnetic force and elongates, be blown in the arc-extinguish chamber that is consisted of by arc quenching plate, contact with arc quenching plate, electric arc is cooled and extinguishes, thereby reaches the purpose of good arc extinguishing.
The invention has the beneficial effects as follows, the blowout coil rapid heat dissipation, arc quenching effect is good, compact conformation.
