Schneider AC contactor price advantage | Product in stock | Product picture | Product price | Zhejiang | Wenzhou | Yueqing | Liushi |
The contactor has low power consumption, long life, safety and reliability, energy saving, high-quality silver contacts, high Resistance to welding and electrical wear.
Series AC contactors are mainly used in circuits with AC (or rated insulation voltage of 0.0000000000. Overload relays form electromagnetic starters to protect circuits that may be overloaded.
Structural features and working principles
Contactors are mainly composed of electromagnetic systems, contact systems, arc extinguishing systems and other parts.
①Electromagnetic system The electromagnetic system includes the electromagnetic coil and the core, which is an important part of the contactor, relying on it to drive the closing and opening of the contacts.
②Contact system The contacts are the executive part of the contactor, including the main Contacts and auxiliary contacts. The function of the main contact is to connect and break the main circuit and control larger currents, while the auxiliary contact
is in the control loop to meet the requirements of various control methods.< br/> ③ Arc extinguishing system The arc extinguishing device is used to ensure that the arc generated when the contacts disconnect the circuit is extinguished reliably and to reduce the damage of the arc to the contacts. In order to quickly extinguish the arc when disconnecting, usually
Contactors are equipped with arc extinguishing devices, generally using semi-sealed longitudinal seam clay arc extinguishing covers and equipped with strong magnetic arc blowing circuits.
④Other parts include insulating shells, springs, short-circuit rings, transmission mechanisms, etc.
Working principle of series AC contactor
When the electromagnetic coil of the contactor is not energized, the reaction force of the spring and the self-weight of the armature core keep the main contact in the off position. When the electromagnetic coil is turned on and controlled through the control loop When the voltage (usually
is the rated voltage), the electromagnetic force overcomes the reaction force of the spring and attracts the armature to the static core, driving the main contact to close, turning on the circuit, and the auxiliary contact moves accordingly.
