Abstract
The utility model relates to a static contact device for an AC contactor, which comprises a copper contact plate (1) and a silver contact point (2). The utility model is characterized in that the silver contact (2) is weldedon the copper contact plate (1); the jaw opening tightly closes to an iron arc-suppressing angle (3). Compared with a static contact device of an existing alternating current contactor, the utility model decreases the stay time of the arc root of the electric arc on the static contact and temperature rise; thereby, the utility model is good for increasing the electrical wear resistance performance of the contacts, and the copper material is saved.
Description
The utility model relates to a kind of static contact head device that is used for A.C. contactor.
Contactor mainly partly is made up of electromagnetic system, contact system and arc quenching system, auxiliary contact, support or shell etc.Contact is the execution unit of contactor, closes by their action and closes (disjunction) circuit, and its work quality directly influences the quality of contactor service behaviour.Contact is in breaking course, and moving contact and fixed contact disengage in "on" position, and when they begin to separate, and between can produce electric arc when the gap occurring in the gap, and this had not only hindered the disjunction but also can make contact burning reliably in time of circuit.Must take suitably and effective measures with the protection contact system, reduce its wearing and tearing for this reason, improve its breaking capacity, thereby guarantee the safe and reliable of whole contactor.At present, wherein a kind of the most adopted method is to add the short arc sheet on moving contact, and adds magnetic guiding loop on fixed contact, as the CJ40 Series AC Contactor.
Task of the present utility model is the static contact head device of existing A.C. contactor is improved, and reduces dead time and the temperature rise of electric arc arc root on fixed contact, is beneficial to improve the anti-electric abrasioning performance of contact, and saves copper material.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of static contact head device that is used for A.C. contactor, comprise copper contact plate, silver contact, and it is characterized in that welding on the copper contact plate that silver contact, opening part are adjacent that an iron arcing born arranged.
Owing to be provided with the iron arcing born, the electric arc that fixed contact (copper contact plate) produces when separating with moving contact very fast from edge transitions to the iron arcing born, so just can very effectively electric arc be transferred on the iron arcing born the ablation effect of fixed contact.The quick transfer of arc root has reduced the temperature rise of contact widely, has reduced the injection of contact material metallic, helps improving the anti-electric abrasioning performance of contact; Because the copper contact plate not only as fixed contact but also as the contactor gusset piece, unites two into one, and compares with the static contact head device of former contactor and has saved copper material (in the prior art, fixed contact is installed on the contactor gusset piece).Increase some costs though increased the iron arcing born, saved copper material, integrated compared with prior art, improved the ratio of performance to price widely.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Accompanying drawing 1 is the front elevational schematic of present embodiment.
Accompanying drawing 2 is vertical views of accompanying drawing 1.
As shown in Figure 1, present embodiment is realized like this: go up weldering silver contact (2) at copper contact plate (1), an iron arcing born (3) arranged in that the opening part of copper contact plate (1) is adjacent.During use, iron arcing born (3) is fixed on the mounting panel of contactor with copper contact plate (1).It installs more convenient than prior art.
Claims (1)
- A kind of static contact head device that is used for A.C. contactor comprises copper contact plate (1), silver contact (2), it is characterized in that: copper contact plate (1) goes up that weldering silver contact (2), opening part are adjacent an iron arcing born (3).
