4.Working principle
The electromagnetic holding type:
Three-phase vacuum tube through the insulator and conductive rod lever,the contact connected to the cantilever springs,cantilevers and armature are fixed on the shaft.
During closing,solenoid armature coil snap-keep,inward movement,the upward motion of the cantilever,vacuum tube through the contact spring contact is closed and provides a contact pressure to ensure reliable close.When switch open,the electromagnetic coil power lose suction opening,moving the armature in the sub-gate under the action of the spring,the outward movement of cantilever downward movement, downward movement by pulling
the lever,pull the insulator,moving conducting rod,contact separation requirements distance to achieve a reliable sub-gate.
Due to electromagnetic systems require larger power in armature snap and snap in place maintain power greatly reduced,in order to save electricity,synchronized by the auxiliary switch snap,maintain conversion.Auxiliary switch also provides user external control you need.With DC excitation of electromagnetic system,auto-control circuits with rectifiers,so users can be controlled directly from the AC power.As the vacuum switch main contacts close/open is conducted in vacuum,which has a good breaking characteristics,long life,safe and reliable.
