The electromagnetic contactor illustrates the principle and structure

。 1. The construction of the structure of the electromagnet electromagnets in figure 2. The principle of electromagnetic contactor structure used for the function of the contactor contactor E shape core principle chart 3. The electromagnetic contactor (the actual structure of the ac contactor 一) CJ10 series contactor ( b） CJX1 series contactor ( c) CJX1N series mechanical interlocking contact ( d） The appearance of ac contactor structure ( e) ( f) Contactor contactor structure: internal structure by the electromagnetic system, contact system, arc extinguishing device and reset spring and so on several parts. Electromagnetic system: including movable core ( Armature) , static iron core, the electromagnetic coil; Contact system: including used to connect, to cut off the main circuit of large current capacity and used in control circuit of the main contact of the small current capacity of auxiliary contacts; Arc extinguishing device: disconnected to quickly cut off the main contact arc, singeing, fusion welding, lest make the main contact for larger capacity of ac contactor, arcing gate is often used to arcing.
