Abstract
The utility model relates to an improved AC contactor with quick arc extinguishing, which is the improvement of a CJ10 type contact system.; other components are the same with the CJ10 type. Mainly, an original static contact is changed a Z-shaped copper static contact (4); an iron arc extinguishing angle (3) is arranged on the circumference thereof; thereby, the temperature rise of the contact is reduced, the jetting of the metal particles of the contact material is reduced, and the utility model is good for increasing the electrical wear proof performance of the contact; for the contact system, the copper material can be saved by 50%, and the production efficiency for producing static contacts can be increased.
Description
The utility model relates to the A.C. contactor in the low-voltage electrical apparatus, refers in particular to CJ10 type modified model A.C. contactor.
Contactor mainly partly is made up of electromagnetic system, contact system and arc quenching system, auxiliary contact, support or shell etc.CJ10 type commonly used at present exchanges the contact structures characteristics: 40A and following grade adopt double break point direct dynamic structure, and formal dress is three-dimensional arranges that contact and arc quenching system are positioned at electromagnetic system the place ahead; The above grade of 60A adopts double break point rotational structure, floor plan; 20A and above grade all adopt potter's clay longitudinal joint arc control device; Adopt two E cores, meet the formula buffer unit head-on.But have following defective in contact system: because fixed contact is to weld silver contact on the copper horizontal U-shaped contact of integral type, arc extinction performance is undesirable, and not high with Sheet Metal Forming Technology making fixed contact production efficiency, and the contact system amount of copper consuming is big.
The purpose of this utility model is to provide a kind of modified model quick arc extinguishing ac contactor, and it improves than fast, the anti-electric abrasioning performance of existing C J10 type A.C. contactor extinguish arcs speed, and has saved copper material.
For achieving the above object, the solution that the utility model is taked is: the quick arc extinguishing ac contactor of a kind of modified model, comprise electromagnetic system, contact system and arc quenching system, auxiliary contact, shell etc., contact system adopts double-breakpoint structure, built-in spring of plastics supporter and iron supporter, the movable contact bridge is put in iron supporter upper end, on the contactor mounting panel connecting plate is installed, on the Z-shaped copper stationary contact crown that shape technique is made, weld silver contact, Z-shaped copper fixed contact embeds irony arcing born opening part, and Z-shaped copper fixed contact is fixed on the connecting plate with the irony arcing born.
The utility model is to carry out improvedly on CJ10 type A.C. contactor, its contact system is redesigned, and other structure all keeps the original structure characteristics.Owing to ferrous material is arranged around the fixed contact, reduced the dead time of electric arc arc root on contact, electric arc is transferred to protection on every side with on the ferrous material to contact ablation agency part ground; Because fixed contact embeds the opening part of arcing born, like this can so that the arc root on the fixed contact can be successfully from the edge transitions of fixed contact to arcing born.The quick transfer of arc root has reduced the temperature rise of contact widely, has reduced the injection of contact material metallic, helps improving anti-electric abrasioning performance.Because fixed contact adopts shape technique to make, production efficiency is than prior art height.Aspect contact system, the utility model is saved about 50% (same specification is compared) of copper material than CJ10 type A.C. contactor.
The utility model will be further described below in conjunction with embodiment and accompanying drawing thereof.
Accompanying drawing 1 is a present embodiment contact system structural representation.
Accompanying drawing 2 is shape figure of Z-shaped copper fixed contact (4) in the accompanying drawing 1.
Present embodiment is to improve to form on the basis of CJ10 type A.C. contactor, comprise electromagnetic system, contact system and arc quenching system, auxiliary contact, shell etc., contact system adopts double-breakpoint structure, mainly static contact structure is redesigned, built-in spring of plastics supporter (6) (8) and iron supporter (7), movable contact bridge (5) is put in iron supporter (7) upper end, contactor mounting panel (1) is gone up connecting plate (2) is installed, welding silver contact (9) on Z-shaped copper fixed contact (4) top that shape technique is made, Z-shaped copper fixed contact (4) embeds irony arcing born (3) opening part, and Z-shaped copper fixed contact (4) is fixed on the connecting plate (2) with irony arcing born (3).
Claims (1)
1. quick arc extinguishing ac contactor of modified model, comprise electromagnetic system, contact system and arc quenching system, auxiliary contact, shell etc., contact system adopts double-breakpoint structure, built-in spring of plastics supporter (6) (8) and iron supporter (7), movable contact bridge (5) is put in iron supporter (7) upper end, contactor mounting panel (1) is gone up connecting plate (2) is installed, it is characterized in that: welding silver contact (9) on Z-shaped copper fixed contact (4) top that shape technique is made, Z-shaped copper fixed contact (4) embeds irony arcing born (3) opening part, and Z-shaped copper fixed contact (4) is fixed on the connecting plate (2) with irony arcing born (3).
