Background

Contactors are classified into alternating current contactors (voltage AC) and direct current contactors (voltage DC), and are applied to electric power, distribution, and power utilization occasions. The contactor is an electric appliance which utilizes a coil to flow current to generate a magnetic field in industrial electricity to close a contact so as to control a load.

The vacuum contactor mainly comprises a vacuum arc-extinguishing chamber and an operating mechanism. The vacuum arc-extinguishing chamber has two functions of reliably extinguishing arc when normal working current is passed and working current is frequently cut off. But not to cut off overload and short-circuit currents. The operating mechanism is composed of a holding coil with an iron core and an armature. Energizing the coil to attract the armature and closing the contactor; and when the coil loses power, the contactor is disconnected. The holding coil generally has two forms of direct current and alternating current. The housing of the vacuum arc-extinguishing chamber is made of glass or ceramic insulating material, and the internal vacuum degree is usually above 0.01 Pa. Because the air in the shell is less, the contact opening distance can be made to be small, and the electric arc is also easily extinguished. The contact material is generally made of copper, antimony, osmium and other alloys. The effect of shield cover in the explosion chamber is that when breaking current, the metallic vapor that diffuses out in the contact clearance that condenses helps putting out an arc, can also prevent that metallic vapor from spattering and falling and reducing its dielectric strength on insulating casing. The moving contact is connected with the lower end of the shell through a corrugated pipe, and the moving contact can move up and down and cannot leak air.

The vacuum contactor is used as a main component of an electric appliance switch, the operation of subordinate equipment is directly influenced by the quality of the vacuum contactor, and contact loss, poor contact, three-phase imbalance and the like can be caused due to frequent starting, inching and the like during use, so that the use cost of the vacuum contactor is overhigh.
