Electromagnetic contactor (contactor) refers to an electrical appliance that uses the current flowing through the coil to generate a magnetic field in industrial electricity to close the contact so as to control the load. The contactor is composed of electromagnetic system (armature, stator core, electromagnetic coil), contact system (normally open contact and normally closed contact) and arc extinguishing device.
Structural composition
Electromagnetic contactor is mainly composed of transmission device (electromagnetic mechanism), contact device (actuator) and arc extinguishing device.
1. Electromagnetic mechanism
The electromagnetic mechanism includes three parts: moving core (armature), static core and electromagnetic coil. The electromagnetic coil is connected with current to generate electromagnetic suction and drive the contact to act.
Electromagnetic mechanism is one of the important parts of electromagnetic contactor. The electromagnetic mechanism is composed of coil, iron core (static iron core), armature (moving iron core), pole shoe, iron yoke and air gap. The coil and iron core in the electromagnetic mechanism do not move in the working state; The armature is movable.
The electromagnetic mechanism converts the electromagnetic energy generated by the electromagnetic coil into mechanical energy through the action state and action process of the armature and the corresponding mechanical mechanism to drive the contact to close or open, so as to realize the control purpose of the controlled circuit.
Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, power distribution and power consumption. Broadly speaking, contactor refers to an electrical appliance that uses the current flowing through the coil to generate a magnetic field and close the contact in order to control the load.
main features
The AC contactor uses the main contact to open and close the circuit and the auxiliary contact to turn on the control circuit.
The main contact is generally normally open contact, while the auxiliary contact often has two pairs of normally open contact and normally closed contact. Small contactors are often used as intermediate relays to cooperate with the main circuit.
The contact of AC contactor is made of silver tungsten alloy, which has good conductivity and high temperature ablation resistance.
The power of AC contactor action comes from the magnetic field generated by AC through the coil with iron core. The electromagnet core is composed of two "mountain" shaped young silicon steel sheets. One of the fixed iron core is sleeved with coil, and the working voltage can be selected. In order to stabilize the magnetic force, a short-circuit ring is added to the suction surface of the iron core. After the AC contactor loses power, it returns by spring.
The other half is a movable iron core, whose structure is the same as that of a fixed iron core, which is used to drive the closing and breaking of the main contact and auxiliary contact.
Description
CJ16(19) switch-over capacitor contactor is
the new type of components for electric
appliances, standard for 400V(50/60Hz) grid, 3P3W connection from 25A~95A. It is
developed and produced on the basis of the
introduced foreign technology of the same
kind.
The device is widely applied to low voltage
reactive power compensation device to
replace the subassembly composed of three
XD1 current-limiting reactors and CJ10
contactor, and it is also can be used in the
general control circuit to limit surge impact, protect capacitor and other electrical device
from over voltage damage.
