Abstract
An electromagnetic blast arc equipment of the AC electromagnetic contactor, comprises an arc extinguish chamber, in which a localizer is arranged with arc extinguishing gate tablets arranged on both sides symmetrically. The out sides of the arc extinguishing gate tablets are all provided with striking arc tablets, and directly under the localizer a moving contact is arranged, at the lower head of which a static contact is arranged symmetrically. The staring head of the electromagnetic loop is connected with the static contact through the base plate of the static contact, and the head of the electromagnetic loop is connected with the striking arc tablet through the down-lead tablet with a blast arc iron core arranged in the electromagnetic loop. The utility model produces alternating magnetic field using the alternating electromagnetic loop in series in the contact circuit when contacts break, quickly blasts the electric arc to the arc extinguishing gate tablets under the effect of the electromagnetic force, extinguishes the electric arc through the arc extinguishing gate tablets, reduces the burning loss of the contacts and prolongs the service life of the contacts.
Description
Technical field
The utility model belongs to the electromagnetism arc blow-out device in low-voltage electrical apparatus field, is specifically related to a kind of alternating electromagnetic contactor electromagnetism arc blow-out device.
Background technology
The alternating electromagnetic contactor is when the contact disjunction, and the electric arc that produces between contact relies on current zero-crossing point and contact loop electric power that electric arc is moved to arc extinguishing grid pieces, and arc extinguishing grid pieces is with arc extinction.Owing to make the electric power of arc motion less, arc motion is slower, so electric arc is bigger to contact burning during the big electric current of disjunction.Facts have proved that the contact electric life that adopts existing arc extinguishing technology can not satisfy in 1 of the locomotive operation repaiies the phase (diesel locomotive 300,000 Km, electric locomotive 40～500,000 Km) non-maintaining requirement.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of simple in structure, can reduce contact burning, prolongs the alternating electromagnetic contactor electromagnetism arc blow-out device in contact life-span.
For achieving the above object, the technical solution adopted in the utility model is: be provided with spacer in arc control device, and the bilateral symmetry at spacer is provided with arc extinguishing grid pieces, the outside of arc extinguishing grid pieces is provided with the striking sheet, be provided with moving contact under the spacer, lower end at moving contact also is symmetrically arranged with fixed contact, be characterized in, the top of blowout coil is connected with fixed contact by the fixed contact backing plate, the end of blowout coil is connected with the striking sheet by lead wire, also is provided with the arc blow-out iron core in the inside of blowout coil.
The utility model also is respectively arranged with magnetic pole plate in the both sides of arc blow-out iron core.
The AC electromagnetic coil that the utility model utilization is serially connected in the contact loop produces alternating magnetic field when the contact disjunction, under the effect of electromagnetic force, rapidly electric arc is blowed to arc extinguishing grid pieces, with arc extinction, reduce the scaling loss of contact by arc extinguishing grid pieces, prolonged the life-span of contact.
Description of drawings
Accompanying drawing is an overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to accompanying drawing, the utility model comprises the arc extinguishing grid pieces 5 that is arranged on spacer 7 both sides by spacer 7, symmetrically, the striking sheet 4 common arc control device of forming 9 that are arranged on arc extinguishing grid pieces 5 outsides, be provided with moving contact 6 under the spacer 7, lower end at moving contact 6 also is symmetrically arranged with fixed contact 1, the top of blowout coil 3 is connected with fixed contact 1 by fixed contact backing plate 10, the end of blowout coil 3 is connected with striking sheet 4 by lead wire 11, inside at blowout coil 3 also is provided with arc blow-out iron core 2, and the both sides of arc blow-out iron core 2 also are respectively arranged with magnetic pole plate 8.
The utility model is connected in series the blowout coil 3 of band arc blow-out iron core 2 between fixed contact 1 and striking sheet 4, when contact disconnected, arc starting blowout coil 3 loops that produce between contact were in 8 moments generations of two magnetic pole plate electromagnetic force, electromagnetic force blows to arc extinguishing grid pieces 5 with electric arc, arc extinguishing grid pieces 5 breaking arcs.When the sense of current between contact changed, blowout coil 3 electric currents also changed thereupon, so the electromagnetic force direction blows to electric arc arc extinguishing grid pieces 5 all the time.
After the alternating electromagnetic contactor installed the utility model additional, contact burning reduced (especially when the big electric current of disjunction) greatly, has prolonged the contact life-span.The utility model is applied on the QCC2-250/322 alternating electromagnetic contactor, and its arc quenching effect has surpassed similar products at home and abroad, and contact has satisfied in 1 of the locomotive operation repaiies the phase (diesel locomotive 300,000 Km, electric locomotive 40～500,000 Km) non-maintaining requirement.
