The ac contactor is mainly composed of contact system, arc extinguishing system and electromagnetic system. Electromagnetic suction when energized coil, the static iron core, will be moving iron core and, as a result of the contact system is with the linkage of moving iron core, so core to drive three move contact run at the same time, the contact closure, and connected to the power supply. Disappear when power coil, suction, moving iron core linkage part rely on spring reaction and separation, make the main contactor disconnect, cut off power supply. Contact is one of the key components of the contactor, its performance directly affects the breaking capacity of the electrical equipment, service life and reliability. Because contact abrasion wear is the main form of electricity, it is the main failure mode of contact of the contact resistance exceed the permitted обхват, свържете се с заваряване и изгаряне на контакт; These failure modes and the contact in the process of our connected or breaking arc related to reduce the negative effects of arc is the key to improve the contact life. Through on both ends of contact with the power electronic devices, make contact opening and closing of instantaneous current shunt, can greatly reduce the production of the arc, thus reducing the contact ablation, significantly improve the reliability of contact life and devices.
[with a number of H62 brass stamping multi-purpose pressure. H65, H68, etc.1, H65: performance between H68 and H62, prices H68 cheap, have good mechanics performance also have higher strength and plasticity, can well under cold and hot pressure processing, are prone to corrosion cracking. Used to produce H65 brass hardware, daily necessities, screws and other parts.2, H62: ordinary brass, good mechanical properties, thermal state of plasticity is good, under the cold plastic can also, good cutting, brazing and welding, corrosion resistant, but easy to produce corrosion cracking. Moreover cheap, is one of the widely used ordinary brass varieties. Can do all kinds of deep Компоненти за напрежение на опън и огъване, като щифт, нитове, шайби, ядки, катетри, барометър пружина, екранна мрежа, части за радиатор и т.н. Сортове . H68 Brass Performance и H70 много подобни, но студена работа от време до том, "сезонен тенденция на пукнатина", използвани като сложно студено щамповане и дълбоко рисуване на части, като гофрирана тръба, черупките на черупките на куршума и т.н. Alphabet) каза "h" . обикновен месинг с "h" каза процентното съдържание на основните елементи на медта, като: 62, представени като H62 месинг, 65, изразено като H65 месинг, H68 по подобен начин
Популярни тагове: щамповани месингови части за контактори на променлив ток, Китай, производители, доставчици, на едро, безплатна проба, Части за медно щамповане, Части за щамповане на желязо, Метални части за щамповане, Части за щамповане със сребърно покритие, Части за щамповане със сребърно никел покритие, Части за щамповане от неръждаема стомана
