Abstract
The invention discloses a non-polar DC contactor. The non-polar DC contactor includes a sealed contact chamber and at least two permanent magnets. Two fixed static contacts and a movable normally open moving contact sheet are arranged in the contact chamber. The moving contact sheet and the two static contacts are vertically arranged to correspond to each other in a fit manner. The at least two permanent magnets are respectively arranged on the two sides of an extending line formed by connection of the two static contacts. The magnetic field directions of the permanent magnets are parallel to the connection line direction of the two static contacts, and also perpendicular to the current direction between moving contacts and the static contacts. The inner structure of a DC contact is improved, and the direction and magnetic field intensity of permanent magnets in the DC contact are adjusted, so the bidirectional on and off performance of the DC contact is achieved while the mounting dimension of the DC contact remains unchanged. Therefore, users do not need to distinguish anodes and cathodes, and the degree of satisfaction of users is improved.
Description
Technical field
The present invention relates to and a kind ofly can automatically control interrupted electronic component, particularly a kind of nonpolarity D.C. contactor of the closed type that can two-wayly cut-off.
Background technology
At present, on market, existing closed type D.C. contactor is utilize permanent-magnetic field to extinguish the electric arc produced when contactor cut-offs mostly, reaches the object of thorough disconnecting consumers.Its concrete principle is: the electric arc produced when utilizing magnetic field to be disconnected contact elongates, and then realizes the thorough disconnection between contact after weakening arc energy.The necessary direction of electric arc of both sides, contact is contrary, just can realize the object of arc extinguishing.When electric arc direction is identical, both sides electric arc crosses, then cannot realize the disconnection between contact.All there is the defect of forward break performance much larger than negative sense break performance in therefore traditional D.C. contactor.
Along with seal DC contactor constantly promoting the use in new-energy automobile industry and photovoltaic device industry, have higher requirement to the negative sense break performance of D.C. contactor, existing D.C. contactor cannot be met consumers' demand.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of nonpolarity D.C. contactor, without the need to distinguishing both positive and negative polarity, there is two-way break performance, can well meet consumers' demand.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of nonpolarity D.C. contactor, comprise sealed type contact chamber and at least two pieces of permanent magnets of a contactor, movable often contact chip is started built with two fixing fixed contacts and one at described contact chamber, moving contacting plate matches with two fixed contacts are vertically corresponding respectively, at least two pieces of described permanent magnets are divided into the both sides of the extended line of two fixed contact lines, and the magnetic direction of this permanent magnet is parallel with two fixed contact line directions and simultaneously with dynamic, the sense of current between fixed contact is vertical.
As a further improvement on the present invention, electric arc insulating wall is provided with between described two fixed contacts.
As a further improvement on the present invention, described moving contacting plate and the width at the fixed contact place of coupling are less than the diameter of described fixed contact.
As a further improvement on the present invention, described contact chamber is that pottery is made, and the cross section of this contact chamber is rectangle, and the width dimension of this contact chamber is greater than the distance between two fixed contacts.
The invention has the beneficial effects as follows: when ensureing that D.C. contactor installation dimension is constant, by improving D.C. contactor internal structure, adjustment D.C. contactor interior permanent magnets direction and magnetic field intensity, realize the two-way performance of cut-offfing of D.C. contactor, thus without the need to distinguishing both positive and negative polarity, improve user satisfaction.

Embodiment
By reference to the accompanying drawings, elaborate to the present invention, but protection scope of the present invention is not limited to following embodiment, the simple equivalence namely in every case done with the present patent application the scope of the claims and description changes and modifies, and all still belongs within patent covering scope of the present invention.
As shown in Figure 1, a kind of nonpolarity D.C. contactor, comprise contact chamber 1 and at least two pieces of permanent magnets 2 of the sealed type of a contactor, movable often start contact chip 4 at contact chamber built with two fixing fixed contacts 3 and one, moving contacting plate matches with two fixed contacts are vertically corresponding respectively.At least two pieces of described permanent magnets are divided into the both sides of the extended line of two fixed contact lines, and the magnetic direction of this permanent magnet is parallel and simultaneously vertical with the sense of current between dynamic and static contact with two fixed contact line directions.
The magnetic direction of permanent magnet is adjusted to parallel with direction, contact by the present invention, when arc blow-out, as state diagram when Fig. 2 .1 is forward current disconnection, wherein, lateral arrows is magnetic direction 11, and vertical arrow is electric arc direction 12 ,+,-be the sense of current 13, now, the electric arc between two fixed contacts pulls open towards both sides under the influence of a magnetic field.When reverse current disconnects, as shown in Fig. 2 .2, the electric arc between two fixed contacts pulls open towards both sides equally, and direction when just electric arc direction disconnects with forward current is contrary.Because both sides magnetic field intensity is consistent, fixed contact both sides are consistent with ceramic package distance simultaneously, and therefore the forward of electric current cut-offs consistent with reverse break performance, thus realizes the identical object of two-way break performance.In addition, the magnetic field intensity of permanent magnet can be increased, to increase arc blow-out effect simultaneously.
The present invention is also provided with electric arc insulating wall 5 between two fixed contacts, electric arc can be separated completely in interrupting process, reaches better arc blow-out effect.
Contact chamber of the present invention is that pottery is made, and the cross section of this contact chamber is rectangle, and the width dimension of this contact chamber is greater than the distance between two fixed contacts.If Fig. 3,1 is when contact chamber shell is circular, electric arc is restricted in the space of extending direction, and electric arc, due to the impact by round ceramic shell, is easily formed and crosses, reduce the connecting-disconnecting function of D.C. contactor electric current, and round ceramic shell is not easy to the installation of permanent magnet and fixes.And the present invention is designed to square ceramic shell, as shown in Figure 3 .2, electric arc is consistent in the space of extending direction, and permanent magnet can be close to ceramic package simultaneously, is convenient to install.If Fig. 4 .1 is narrow ceramic package, Fig. 4 .2 is wide type ceramic package, and the present invention, by increasing the lateral dimension of square ceramic shell, strengthens the space of electric arc extending direction, thus is more conducive to cut-offfing of electric arc.
In addition, the diameter connecing moving contacting plate and the width at the quiet contact point place of coupling and be less than described fixed contact of the present invention, such setting also can improve the connecting-disconnecting function of D.C. contactor.As the moving contacting plate that Fig. 5 .1 is wider, and Fig. 5 .2 is narrower moving contacting plate, and the electric arc in visible Fig. 5 .2 more easily disconnects.
