Description of this High Phase Electric Magnetic Ac Contactor

High phase Electric Magnetic ac contactor, the principle is that when the electromagnetic coil of the contactor is energized, it will generate a strong magnetic field, so that the static iron core generates electromagnetic attraction to attract the armature and drive the contact action: the normally closed contact is disconnected, often open The head is closed and the two are linked. When the coil is de-energized, the electromagnetic attraction disappears and the armature is released under the action of the release spring to restore the contact: the normally closed contact is closed and the normally open contact is opened. In industrial electrical, there are many types of contactors, and the current varies from 5A to 1000A, and its use is quite extensive. In electrical engineering, a contactor is an automatic switcher for switching on or off a load-carrying AC/DC main circuit or a large-capacity control circuit. The main control object is an electric motor, and is also used for other electric loads, such as electric heating. Devices, welding machines, lighting equipment, and contactors not only turn the circuit on and off, but also have low voltage release protection. The contactor has a large control capacity. Suitable for frequent operation and remote control. It is one of the important components in the automatic control system.

The High phase Electric Magnetic ac contactor uses the main contacts to open and close the circuit and the auxiliary contacts to conduct the control loop. The main contacts generally have only normally open contacts, while the auxiliary contacts often have two pairs of contacts with normally open and normally closed functions. Small contactors are often used as intermediate relays in conjunction with the main circuit. The high phase electromagnetic contactor is made of silver-tungsten alloy and has good electrical conductivity and high temperature ablation resistance. The electrodynamic AC contactor is powered by an alternating current electromagnet. The electromagnet is made up of two “mountain” shaped silicon steel sheets. One of them is fixed, and the coil is placed on it. There are various operating voltages to choose from. In order to stabilize the magnetic force, the suction surface of the iron core is added with a short-circuit ring. The high phase contactor relies on a spring to reset after a loss of power. The other half is a movable iron core, which is constructed like a fixed iron core to drive the main and auxiliary contacts. The contactor of 20 amps or more is equipped with an arc extinguishing cover, and the electromagnetic force generated when the circuit is broken is used to quickly break the arc to protect the joint. The contactor has a high frequency for power on and off control, and the maximum operating frequency is even 1200 times per hour. The life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally hundreds of thousands to millions of times.
