電(dian)(dian)(dian)動(dong)機(ji)保護(hu)器(qi)的工作(zuo)原理是通過對(dui)三相運(yun)行電(dian)(dian)(dian)流進行檢(jian)測，根據運(yun)行電(dian)(dian)(dian)流的不(bu)同性(xing)質來(lai)確(que)定不(bu)同的保護(hu)方(fang)(fang)式，從而對(dui)電(dian)(dian)(dian)機(ji)予以的斷(duan)電(dian)(dian)(dian)保護(hu)。當電(dian)(dian)(dian)動(dong)機(ji)保護(hu)器(qi)檢(jian)測到電(dian)(dian)(dian)動(dong)機(ji)出(chu)(chu)現過流、負序電(dian)(dian)(dian)流、零序電(dian)(dian)(dian)流、電(dian)(dian)(dian)壓不(bu)足(zu)、過熱(re)等問題時(shi)，就會(hui)立即切(qie)斷(duan)電(dian)(dian)(dian)源，避免(mian)電(dian)(dian)(dian)動(dong)機(ji)繼續運(yun)轉而引發故(gu)障。此外，電(dian)(dian)(dian)動(dong)機(ji)保護(hu)器(qi)還能夠對(dui)電(dian)(dian)(dian)動(dong)機(ji)的啟動(dong)和停止(zhi)進行控制，并在發生(sheng)故(gu)障時(shi)及時(shi)發出(chu)(chu)報警(jing)信號。理想的電(dian)(dian)(dian)動(dong)機(ji)保護(hu)器(qi)應(ying)滿足(zu)可(ke)靠、經濟、方(fang)(fang)便等要素，具有較高的性(xing)能價格比。
