The utility model is characterized in that an arc jetting port 12 is arranged between a cover plate 4 and an arc extinguishing cover 3, forming a semi-closed arc extinguish chamber; a corresponding arc striking sheet 5 is arranged above a moving contact bridge 16; longitudinal grating slices 8 and transversal grating slices 9 are longitudinally arranged on both sides of the arc striking sheet 5. The utility model has the advantages of high strength, difficult break, convenient assembly and disassembly, zero arcing realization, high safety and convenient maintenance, assembly and disassembly. The contact is made of copper base without silver alloy.
Description
The utility model relates to A.C. contactor, is specially a kind of AC contactor arc control device.
At present, the A.C. contactor that uses in state adopts longitudinal joint potter's clay arc-extinguish chamber more, and base plate is a porcelain.Its shortcoming is frangible, and the arcing time is long, and flashover distance is big, and contact adopts Pd-Ag substrate alloy material, cost height, a large amount of noble metal silver of annual consumption.
It is a kind of semi-enclosed that the purpose of this utility model is to provide, be difficult for broken, zero arcing, A.C. contactor contact arc-extinguishing device with low cost.
The purpose of this utility model is achieved in that between cover plate 4 and the arc-extinguish chamber 3 arc spraying mouth 12, form semiclosed arc control device, above movable contact bridge 16 to striking sheet 5 should be arranged, vertical grid sheet 8 of vertical arrangement, horizontal grid sheet 9 are arranged in the both sides of striking sheet 5, vertically there is being a narrow slit to form a space between grid sheet 8, horizontal grid sheet 9 terminations and the cover plate 4, laterally 10 of two contacts of grid sheet 9 rectangular end distances have certain distance, by screw striking sheet 11 are fixed in to face contact 10 on the stationary contact bridge 2.Laterally grid sheet 9 rectangular end distance contacts 10 are 2.5-3.0mm.Distance is 5-6mm between striking sheet 11 and the contact 10.
The utility model advantage is: simple in structure, with low cost, difficult broken, can realize zero arcing, safe and reliable, maintenance, easy accessibility.

Below in conjunction with accompanying drawing in detail the utility model most preferred embodiment is described in detail: between cover plate 4 and the arc-extinguish chamber 3 arc spraying mouth 12 is arranged, form semiclosed arc control device, above movable contact bridge 16 to striking sheet 5 should be arranged, vertical grid sheet 8 of vertical arrangement, horizontal grid sheet 9 are arranged in the both sides of striking sheet 5, vertically there is being a narrow slit to form a space between grid sheet 8, horizontal grid sheet 9 terminations and the cover plate 4, laterally 10 of two contacts of grid sheet 9 rectangular end distances have certain distance, by screw striking sheet 11 are fixed in to face contact 10 on the stationary contact bridge 2.Laterally grid sheet 9 rectangular end distance contacts 10 are 2.5-3.0mm.Distance is 5-6mm between striking sheet 11 and the contact 10.In arc-extinguish chamber 3, have and the corresponding three groups of grating arc-extinguishing chamber of three-phase contact.Vertically grid sheet 8 and horizontal grid sheet 9 are staggered, and soon wherein the formation right angle end of 1 to 2 horizontal grid sheet 9 extends to 10 of two contacts, and vertically grid sheet 8 is perpendicular in the arc-extinguish chamber 3, and its end is a profile of tooth, the resistance when entering to reduce electric arc.Laterally the quantity of grid sheet 9 is relevant with the contactor capacity, rated current smaller is a slice, rated current the greater is two, when the disjunction of contactor on-load, and contact 10 contacts on movable contact bridge 6, the stationary contact bridge 2, produce electric arc, electric arc is subjected to horizontal grid sheet 9 and attracts, and makes electric arc enter arc extinguishing grid pieces group (vertically grid sheet 8, horizontal grid sheet 9) rapidly, is divided into the short arc of a plurality of series connection, arc extinction when current over-zero, circuit is by disjunction.Be connected with irony striking sheet 5 and striking sheet 11 respectively above the movable contact bridge 6 He on the stationary contact bridge arc angle.Its magnetic field suction electric arc root contact 10 that speeds away is to reduce ablation and the wearing and tearing of electric arc to contact.Electric arc is subjected to strong cooling and goes to dissociate, thereby realize zero arcing through horizontal grid sheet 9, vertically when grid sheet 8 and narrow slit 13.7 is the contact supporting of movable contact bridge 6.Contact 10 is welded on respectively on stationary contact bridge 2, the movable contact bridge 6.Striking sheet 11 is to be fixed on the stationary contact bridge 2 by screw.The utility model course of work is such: when the solenoid of contactor during by electric current, armature drives rotating shaft 14 clockwise directions and rotates, and supports 7 thereby drive contact, and touches bridge 6 by contact support 7 pullings and move right to 2 contacts of stationary contact bridge.Be switched on by the external circuit that screw 15 connects this moment, reaches the purpose of connecting circuit.When the solenoid voltage out of hand of contactor, armature drives rotating shaft 14 at the reaction force of back-moving spring and counterclockwise rotates, and drives contact and supports 7, and movable contact bridge 6 makes movable contact bridge 6, stationary contact bridge 2 separately to left movement, reaches the purpose of open circuit.When movable contact bridge 6 separates with stationary contact bridge 2, produce electric arc between the contact, this electric arc is pulled out between contact rapidly under the effect of striking sheet 5,11, horizontal grid sheet 9, and by vertically grid sheet 8 suctions, be divided into many short electric arcs, during the circuit zero passage, electric arc will extinguish easily in the circuit, electric arc and free gas are through vertically grid sheet 8, horizontal grid sheet 9 and narrow slit 13 are cooled off realization zero arcing.The utility model contact 10 is the copper-based non-silver contact.
