熱過載繼電器用于電機(jī)過載保護(hù),當(dāng)電動(dòng)機(jī)過載達(dá)到一定程度時(shí),熱元件被加熱達(dá)到一定彎曲程度,推動(dòng)熱繼電器動(dòng)作結(jié)構(gòu)。熱繼電器的動(dòng)作時(shí)間與過載電流的大小按反時(shí)限關(guān)系變化〔而作為電動(dòng)機(jī)過載保護(hù)的熱繼電器,必須保證電動(dòng)機(jī)的正常起動(dòng)和運(yùn)行不受影響,并能最大限度的發(fā)揮電動(dòng)機(jī)的承載能力,因此熱繼電器的動(dòng)作特性曲線應(yīng)位于電動(dòng)機(jī)的允許發(fā)熱特性曲線的下方,且又接近于它)。
