三、接触器工作原理- -结构
Three. The working principle of contactor - structure
交流接触器主要包括电磁系统、触头系统、灭弧装置及其他附件四大部分构成。其中,电磁系统包括吸引线圈、静铁芯和动铁芯;触头系统与动铁芯连接在一起相互联动,主要包括三组主触头和一两组常开、常闭辅助触头;灭弧装置用于迅速切断电源,避免烧坏主触头,常装于容量较大的交流接触器中;除以上三大部分外,交流接触器还包括绝缘外壳、各种弹簧、传动机、接线柱等附件。
The AC contactor mainly consists of four parts, the electromagnetic system, the contact system, the arc extinguishing device and other accessories. The system includes electromagnetic attraction coil, a static iron core and a movable iron core; the contact system and the movable core connected together with mutual linkage, mainly includes three main contact group and one or two groups of normally open and normally closed auxiliary contact; arc extinguishing device for quickly cut off the power supply, to avoid damage of main contact, often installed in the large capacity of AC contactor in addition to the above three parts; and the AC contactor also comprises an insulating shell, all kinds of spring, motivation, terminals and other accessories.
四、接触器工作原理
Four. The working principle of contactor
当线圈通电时,静铁芯产生电磁吸力,使得动铁芯被吸合,进而带动触头系统的三条动触片发生动作,主触点闭合,辅助常闭触点断开,辅助常开触点闭合,接通电源。
When the coil is energized, the static core produces electromagnetic attraction, so that the moving core is absorbed, thus driving the three moving contacts of the contact system to act. The main contacts are closed, the auxiliary normally closed contacts are disconnected, the auxiliary open contacts are closed, and the power is connected.
当线圈断电时,静铁芯的电磁吸力消失,弹簧的反作用力使得动铁芯与静铁芯分离,触头系统的三条动触片动作,使得主触头断开,辅助常闭触点闭合,辅助常开触点断开,切断电源。
When the coil is cut off, the electromagnetic attraction of the static core is disappearing. The reaction force of the spring causes the separation of the moving core and the static core, and the action of the three moving contacts of the contact system causes the main contact to be broken, and the auxiliary closed contact is closed, and the auxiliary open contact is disconnected, and the power is cut off.
