Abstract
The utility model discloses a bipolar strong arc extinguishing DC contactor with function of strong arc extinguishing, comprising an electronic magnetic system; a contact system; a honeycomb main arcextinguishing chamber (2) arranged at a moving contact and a static contact (1, 6); a circular arc conductive striking sheet (3) arranged at the backside of the main arc extinguishing chamber (2), wherein the conductive striking sheet (3) is led out from an opening-closing part of the moving contact and the static contact (1, 6) and provided with a ridge inside; and a magnet (5) disposed at the lower part of the main arc extinguishing chamber (2). The utility model is mainly used for remote control of connection and disjunction of DC circuit, like the railway, the communication and the steel-making, etc.
Description
Technical field
The utility model relates to contactor, specifically is a kind of D.C. contactor.
Background technology
D.C. contactor electric arc when dropping into and cut off is bigger, will adopt special measure to its arc extinguishing, and the arc quenching effect of prior art can not be satisfactory.
The utility model content
Technical problem to be solved in the utility model provides a kind of bipolar strong arc extinguishing D.C. contactor, and it has strong arc extinguishing function.
For solving the problems of the technologies described above, the utility model adopts the basic design of technical scheme to be: comprise electromagnetic system, contact system, also be included in the cellular main arc control device that dynamic and static contact place is provided with, circular-arc conduction striking sheet in main arc control device rear side installation, this conduction striking sheet is driven, draw the fixed contact opening and closing place, be provided with the ridge Gu therebetween and be located at the magnet of main arc control device below.
Described main arc control device comprise that 3～5 have the potter's clay sheet of groove in length and breadth, and this potter's clay sheet is by using the clamp clamping at dynamic and static contact place; Described contact system adopts two groups of contacts that are connected in series; Described electromagnetic system adopts the direct solenoid system.
The beneficial effects of the utility model are, adopt the co-ordinative construction of main arc control device, conduction striking sheet and magnetic blow-out, effective arc extinguishing, and two groups of contacts adopt the reinforcement arc extinguishing that is connected in series.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further described.
Fig. 1 is structural representation of the present utility model (electromagnetic system does not draw), and Fig. 2 is the front view of potter's clay sheet, and Fig. 3 is the superimposed mode schematic diagram of potter's clay sheet, and Fig. 4 is the vertical view of Fig. 2, and Fig. 5 is the structural representation of main arc control device.
Among the figure: moving contact 1 main arc control device 2 conduction striking sheets 3 joints 4 magnet 5 fixed contacts 6 clamps 7 potter's clay sheets 8
Embodiment
Fig. 1 is structural representation of the present utility model (electromagnetic system does not draw).The potter's clay sheet 8 of arc chute constitutes main arc control device 2 by having in length and breadth, the structure of potter's clay sheet 8 such as Fig. 2 and shown in Figure 4, the structure of main arc control device 2 as shown in Figure 5, potter's clay sheet 8 also can be made of the other materials with arc extinction performance, potter's clay sheet 8 according to design needs sheet number is overlapped into honeycomb fashion, superimposed mode as shown in Figure 3, form at dynamic and static contact 1,6 places with clamp 7 clampings, the electric arc that occurs when contactor opens and closes enters under the magnetic blow-out effect in the groove in length and breadth of main arc control device 2, electric arc is cut apart in honeycomb, disperseed and cools off, reach the purpose of arc extinguishing.Conduction striking sheet 3 elongates a part of remaining electric arc under the magnetic blow-out effect, also can disperse cooling to the both sides of ridge Gu, reaches the purpose of blow-out, and free gas is discharged from the cover hole; Magnetic blow-out small dimension permanent magnet 5, big specification solenoid; Two groups of contacts adopt and are connected in series; Electromagnetic system adopts the direct solenoid system in the ordinary course of things, and electromagnetic system also can adopt ac electromagnetism system when instantaneous operation.
