AC contactors often use three arc extinguishing methods: double-break electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the moving and static contacts during the opening and closing process. Contactors with a capacity of more than 10A have arc extinguishing devices. AC contactors also have auxiliary components such as reaction springs, buffer springs, contact pressure springs, transmission mechanisms, bases and terminals. The working principle of the AC contactor is to use the electromagnetic force to cooperate with the spring force to realize the connection and disconnection of the contacts. The AC contactor has two working states: de-energized state (release state) and electrified state (action state). When the attraction coil is energized, the static iron core generates electromagnetic attraction, the armature is pulled in, and the connecting rod connected to the armature drives the contact to move, so that the normally closed contact breaker is in an electrified state; when the attraction coil is de-energized, the The electromagnetic attraction disappears, the armature is re-opened, the normally open contacts are closed and released under the action of the position spring, all the contacts are reset accordingly, and the contactor is in a power-off state. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #contactor #ACcontactor #ZJSHUYI #BypassContactor #Chinashuyi #shuyitop
