Abstract
A novel direct current contactor comprises a coil, a double E-shaped iron core, an auxiliary contact group, a base and an arc extinguishing system, the technical points of the novel direct current contactor are that the two sides of a bipolar bridging main contact in the arc extinguishing system are respectively provided with an arc extinguishing chamber for putting out electric arcs, two-stage electric arcs are respectively pulled into the arc extinguishing chambers which are respectively internally equipped with vertical permanent magnet blocks and arc extinguishing hoods, arc insulating hoods are arranged at the peripheries of the arc extinguishing chambers, and an arc insulting plate is positioned between the arc extinguishing chambers. The technical characteristics of the novel direct current contactor are that the bridging main contact has direct-acting double-break structure, and the vertical permanent magnet blocks are arranged at two sides of the bridging contact. The novel direct current contactor has the advantages that the arcing time can not be long when breaking low current, and the contact can not be over abraded when breaking heavy current, compared with the existing contactors, the novel direct current contactor has reasonable structure and can reliably extinguish electric arcs, which lays a better foundation of power equipment localization. The novel direct current contactor also has the advantages of safe and reliable performance, light weight, small volume, convenient maintenance, large application area and long life time.
Description
Technical field
The utility model belongs to the low-tension switch electric appliance technical field, specifically a kind of circuit breaker operation mechanism that is used for, the Novel DC contactor of remote connection and disjunction primary cut-out.
Background technology
At present, the D.C. contactor that enterprise generally uses is as CZ0, CZ18 series, although these products have satisfied the needs of enterprise, but still have more deficiency, the one, the actual instructions for use of voltage, current class and user does not match, as: the electromagnetic operating mechanism electric pressure of primary cut-out is DC220V, DC110V, and drop-out current is the contour sense load of DC120A, DC240A; In actual use, because the appropriate products that does not match can only be a low load with strong power, economy is very poor.In addition, the arc quenching method of above-mentioned old product is a Petersen coil series connection arc blow-out, and shortcoming is that volume is big, and magnetic blow-out power is little when extinguishing little electric current, and the arcing time is oversize breaks down easily; When extinguishing big electric current, because the power of blowing is too big, the contact excessive wear can take place and useful life of reducing this contactor.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation, volume little, utilize permanent magnetism arc extinguishing technology electric arc to be guided to the Novel DC contactor of cooling extinguish arcs in the arc control device.
The purpose of this utility model is achieved in that it includes coil, two E sections core, sets of contacts, pedestal, arc quenching system, it is characterized in that: respectively there are the arc control device of an extinguish arcs the bipolar bridge-type main contact both sides in the arc quenching system, the electric arc of two-stage is moved to respectively in separately the arc control device, vertical permanent magnets and arc-extinguish chamber are set respectively in arc control device, periphery at arc control device is provided with the arc cover, is provided with flash barrier between arc control device.
D.C. contactor advantage of the present utility model is: it comprises straight vertical dynamic formula electromagnetic system, arc quenching system, bridge-type main contact and auxiliary contact, and technical characterstic is that the bridge-type main contact is the Direct Action Type double-breakpoint structure, in the both sides of bridge contact vertical permanent magnets is installed.The little electric current of disjunction is that can not the arcing time to occur long, and the advantage that contact can inordinate wear during the big electric current of disjunction is compared with existing contactor, its reasonable in design, and reliable extinguish arcs is for the power equipment production domesticization is laid a good foundation.Utilize permanent magnetism arc extinguishing technology, reliable extinguish arcs reduces the contact wearing and tearing, increases the useful life of contactor.The utility model has also that performance is safe and reliable, in light weight, volume is little, easy to maintenance, range of application is wide, the characteristics of long service life.

To be described in further detail utility model by example below; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Shown in Fig. 1～3, this structure mainly comprises: 8 among the figure is pedestal, articulates two 9 sets of contacts in the both sides of pedestal 8; By the electromagnetic system that coil 6 and two E core 7 constitute, this coil 6 adopts instantaneous duty, finishes once and cuts off coil power immediately behind the combined floodgate, otherwise burn coil; Respectively there are the arc control device of an extinguish arcs bipolar bridge-type main contact both sides in the arc quenching system, the electric arc of two-stage is moved to respectively in separately the arc control device, in arc control device, be respectively arranged with a vertical permanent magnets 4 and an arc-extinguish chamber 3, periphery at arc control device is provided with arc cover 1, is provided with flash barrier 2 between arc control device.
Above-mentioned bipolar bridge-type main contact technical parameter: main contact can cut-off the 120A electric current moment.
Arc quenching system: respectively there are arc control device bipolar bridge-type main contact both sides, the electric arc of two-stage are moved in separately the arc control device to extinguish arcs respectively.Arc quenching system is made of arc cover 1, flash barrier 2, arc-extinguish chamber 3, vertical permanent magnets 4.
The power supply word board 5 of the mains side of contactor major loop and the load word board 10 of load-side have requirement, paste power supply word board 5 and load word board 10 in arc cover 1 both sides of this contactor, indicate the both positive and negative polarity and the load-side of power supply, are convenient to the correct wiring of user,
The polarity of permanent magnetism has requirement, and every block of permanent magnetism all is that N is extremely outside, and like this, electric arc just can be elongated guides to cooling rapidly in the arc control device.
The technical solution of the utility model is: utilize electric power that electric arc is drawn, long moving in the arc-chutes reaches the effect of arc extinguishing.
