熱繼電器主要是用于電氣設備(主要是電動機)的過負荷保護。熱繼電器是一種利用電流熱效應原理工作的電器，它具有與電動機容許過載特性相近的反時限動作特性，主要與接觸器配合使用，用于對三相異步電動機的過負荷和斷相保護三相異步電動機在實際運行中，常會遇到因電氣或機械原因等引起的過電流(過載和斷相)現(xiàn)象。如果過電流不嚴重，持續(xù)時間短，繞組不超過允許溫升，這種過電流是允許的;如果過電流情況嚴重，持續(xù)時間較長，則會加快電動機絕緣老化，甚至燒毀電動機，因此，在電動機回路中應設置電動機保護裝置。常用的電動機保護裝置種類很多，使用**多、**普遍的是雙金屬片式熱繼電器。雙金屬片式熱繼電器均為三相式，有帶斷相保護的和不帶斷相保護的兩種。

</p> <p> 使用熱繼電器對電動機進行過載保護時，將熱元件與電動機的定子繞組串聯(lián)，將熱繼電器的常閉觸頭串聯(lián)在交流接觸器的電磁線圈的控制電路中，并調節(jié)整定電流調節(jié)旋鈕，使人字形撥桿與推桿相距一適當距離。當電動機正常工作時，通過熱元件的電流即為電動機的額定電流，熱元件發(fā)熱，雙金屬片受熱后彎曲，使推桿剛好與人字形撥桿接觸，而又不能推動人字形撥桿。常閉觸頭處于閉合狀態(tài)，交流接觸器保持吸合，電動機正常運行。
