C825KN10? ?接觸器
在電工學(xué)上，因為接觸器是一種可快速切斷交流與直流主回路且可頻繁地接通與關(guān)斷大電流控制(達800A)電路的裝置,所以經(jīng)常運用于電動機。
作為控制對象，也可用作控制工廠設(shè)備、電熱器、工作母機和各樣電力機組等電力負載，接觸器不僅能接通和切斷電路，而且還具有低電壓釋放保護作用。接觸器控制容量大,適用于頻繁操作和遠距離控制，是自動控制系統(tǒng)中的重要元件之一。
接觸器作為-一個大功率開關(guān)器件,廣泛應(yīng)用于航天、航空、兵器、船舶、電子等系統(tǒng)裝備中，其控制的負載電流大于25A,電壓為25VDC:
115VAC、402Hz; 386VAC、50Hz,在裝備中主 要作為配電開關(guān)進行電源控制或者控制大功率電機的啟?？刂频龋茄b備中的一一個關(guān)鍵器件，起著重要的作用。在工業(yè)電氣中，接觸器的型號很多,工作電流在5A- 1000A的不等，其用處相當(dāng)廣泛。
接觸器的工作原理是:當(dāng)接觸器線圈通電后，線圈電流會產(chǎn)生磁場,產(chǎn)生的磁場使靜鐵芯產(chǎn)生電磁吸力吸弓|動鐵芯，并帶動交流接觸器點動作，常閉觸點斷開，常開觸點閉合，兩者是聯(lián)動的。當(dāng)線圈斷電時，電磁吸力消失,銜鐵在釋放彈簧的作用下釋放，使觸點復(fù)原，常開觸點斷開，常閉觸點閉合。直流接觸器的工作原理跟溫度開關(guān)的原理有點相似。

In electrical engineering, because the contactor is a device that can quickly cut off the AC and DC main circuit and can frequently turn on and off the large current control (up to 800A) circuit, it is often used in motors.
As a control object, it can also be used to control the power load of factory equipment, electric heaters, working machines and various power units, and the contactor can not only switch on and off the circuit, but also has a low voltage release protection effect. Contactor control capacity is large, suitable for frequent operation and remote control, is one of the important components in automatic control system.
Contactor as a high-power switching device, widely used in aerospace, aviation, weapons, ships, electronics and other systems and equipment, its control of the load current is greater than 25A, the voltage is 25VDC:
115VAC, 402Hz; 386VAC, 50Hz, in the equipment is mainly used as a distribution switch for power control or control of high-power motor start-stop control, etc., is a key device in the equipment, plays an important role. In industrial electricity, there are many models of contactors, and the working current varies from 5A-1000A, which is quite useful.
The working principle of the contactor is as follows: when the contactor coil is energized, the coil current will generate a magnetic field, the magnetic field generated makes the static iron core produce electromagnetic suction to draw the | moving iron core, and drives the AC contactor point action, normally closed contact is disconnected, normally open contact is closed, the two are linked. When the coil is powered off, the electromagnetic suction disappears, and the armature is released under the action of the release spring, so that the contact is restored, the normally open contact is disconnected, and the normally closed contact is closed. The working principle of a DC contactor is somewhat similar to that of a temperature switch.
