2、質(zhì)量等級對繼電器可靠性的影響：當選用A1質(zhì)量等級的繼電器時，平均故障間隔時間可達3660000h，而選用C等級的繼電器平均故障間隔時間為110000，其間相差33倍，可見繼電器的質(zhì)量等級對其可靠性能的影響非常大。 </p> <p> 3、觸點形式對繼電器可靠性的影響：繼電器的觸點形式也會對其可靠性產(chǎn)生影響，單擲型繼電器的可靠性都高于相同刀數(shù)的雙擲型繼電器，同時隨刀數(shù)的增加可靠性逐漸降低，單刀單擲繼電器的平均故障間隔時間是四刀雙擲繼電器的5.5倍。 </p> <p>

熱<strong>繼電器</strong>的工作原理（一） </p> <p> 熱繼電器是用于電動機或其它電氣設(shè)備、電氣線路的過載保護的保護電器。 </p> <p> 電動機在實際運行中，如拖動生產(chǎn)機械進行工作過程中，若機械出現(xiàn)不正常的情況或電路異常使電動機遇到過載，則電動機轉(zhuǎn)速下降、繞組中的電流將增大，使電動機的繞組溫度升高。若過載電流不大且過載的時間較短，電動機繞組不超過允許溫升，這種過載是允許的。但若過載時間長，過載電流大，電動機繞組的溫升就會超過允許值，使電動機繞組老化，縮短電動機的使用壽命，嚴重時甚至會使電動機繞組燒毀。所以，這種過載是電動機不能承受的。熱繼電器就是利用電流的熱效應(yīng)原理，在出現(xiàn)電動機不能承受的過載時切斷電動機電路，為電動機提供過載保護的保護電器。
