Description
Technical field
The present invention relates to D.C. contactor, more particularly to a kind of arc extinguishing structure of D.C. contactor.
Background technology
D.C. contactor is also easy to produce electric arc in use, and electric arc can influence the electric life of contactor.Now, it is conventional
Arc quenching method is " magnetic quenching ", and charged particle is influenceed in magnetic field by long-range navigation magnetic force so that electric arc is elongated so as to reach
The effect of arc extinguishing.Relatively common nonpolarity magnet steel arc extinguishing arrangement mode is two that permanent magnet is placed on the static contact line of centres
Side, N poles are extremely staggered relatively with S.
As shown in figure 1, two magnet steel 3 are just arranged on two lines of centres of static contact 1 and set in the same direction, i.e. two magnet steel
3 N, S is extremely relative, and moving contact 2 is arranged between two magnet steel 3.The structure of two permanent-magnet steels of this set, by product design
The limitation of size, the appearance and size of magnet steel is smaller, and magnetic induction intensity is smaller caused by magnet steel.This D.C. contactor is in high current
Under high-pressure situations, magnetic induction intensity caused by the mounting means of two blocks of magnet steel is often not big enough, and arc quenching effect is bad, such as selects
With the magnet steel with good material, then it can increase cost.
The content of the invention
In view of the above the shortcomings that prior art, it is an object of the invention to provide one kind can make product high current,
Also the modified D.C. contactor arc extinguishing structure of good arc quenching effect can be realized under high-pressure situations.
In order to achieve the above objects and other related objects, the present invention provides a kind of modified D.C. contactor arc extinguishing structure,
Including cavity, two static contacts, moving contacts are provided with the cavity, the static contact is relative with the moving contact position, described
Two the first magnet steel are additionally provided with cavity, two the first magnet steel are arranged on described two static contact lines of centres, the cavity
Two the second magnet steel are inside additionally provided with, described two second magnet steel are separately positioned on the both sides of described two static contact lines of centres.
Preferably, described two second magnet steel are arranged on the perpendicular bisector of described two static contact lines of centres.
Preferably, first magnet steel, the second magnet steel are set in the same direction.
Preferably, groove is provided with the cavity, first magnet steel, the second magnet steel are in the groove.
Preferably, the static contact connects with cavity interference fit.
As described above, the modified D.C. contactor arc extinguishing structure of the present invention has the advantages that：The modified is straight
Stream contactor arc extinguishing structure adds two the second magnet steel as transition magnet steel on the basis of original two piece of first magnet steel, two
Transition magnet steel is individually positioned in the both sides side of two static contact lines of centres, can so strengthen the magnetic induction between original two blocks of magnet steel
Intensity, equivalent to the stiffening device that magnetic induction intensity is added between the magnet steel of two blocks of left and right, magnetic induction intensity is substantially increased,
The arc extinguishing ability of contactor is improved, so as to improve the contactor life-span, expands application.

Refer to Fig. 1,2,3.It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to
Coordinate the content disclosed in specification, so that those skilled in the art understands and reads, being not limited to the present invention can be real
The qualifications applied, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influenceing the effect of present invention can be generated and the purpose that can reach, all should still fall in disclosed skill
Art content is obtained in the range of covering.Meanwhile in this specification it is cited as " on ", " under ", "left", "right", " centre " and
The term of " one " etc., understanding for narration is merely convenient to, and is not used to limit the enforceable scope of the present invention, its relativeness
It is altered or modified, in the case where changing technology contents without essence, when being also considered as the enforceable category of the present invention.
As shown in Figure 2,3, the present invention provides a kind of modified D.C. contactor arc extinguishing structure, including cavity 4, in cavity 4
Provided with two static contacts 1, moving contact 2, the shell interference fit of two static contacts 1 and cavity 4 connects, one end position of static contact 1
In in cavity 4, static contact 1 is relative with the position of moving contact 2.Two the first magnet steel 5 and two the second magnet steel 6 are provided with cavity 4,
Two the first magnet steel are arranged on the line of centres of two static contacts 1, and two the second magnet steel 2 are separately positioned in two static contacts
The both sides of heart line.Two 5 equidirectional placements of the first magnet steel（N, S of i.e. two magnet steel are extremely relative）, two the second magnet steel 6 and two
The placement direction of individual first magnet steel 5 is identical.
As a kind of preferred embodiment, two the second magnet steel 6 are arranged on the perpendicular bisector of two lines of centres of static contact 1
On, it can so make cavity intrinsic inductance more uniform, while can further increase magnetic induction intensity.For the ease of peace
Dress, groove can be provided with cavity 4, by the first magnet steel 5, the second magnet steel 6 in groove.
The modified D.C. contactor arc extinguishing structure adds two the second magnetic on the basis of original two piece of first magnet steel
Steel is individually positioned in the both sides side of two static contact lines of centres, can so strengthen original as transition magnet steel, two transition magnet steel
The first magnetic induction intensity between two blocks of magnet steel, equivalent to the stiffening device that magnetic induction intensity is added between the magnet steel of two blocks of left and right,
Magnetic induction intensity is substantially increased, improves the arc extinguishing ability of contactor, so as to improve the contactor life-span, expands application.
So the present invention effectively overcomes various shortcoming of the prior art and has high industrial utilization.
