<br /> </p> <p> <br /> </p> <p> 熱<strong>繼電器</strong>的工作原理（三） </p> <p> 若電動(dòng)機(jī)出現(xiàn)過載情況，繞組中電流增大，通過熱繼電器元件中的電流增大使雙金屬片溫度升得更高，彎曲程度加大，推動(dòng)人字形撥桿，人字形撥桿推動(dòng)常閉觸頭，使觸頭斷開而斷開交流接觸器線圈電路，使接觸器釋放、切斷電動(dòng)機(jī)的電源，電動(dòng)機(jī)停車而得到保護(hù)。 </p> <p> 熱繼電器其它部分的作用如下：人字形撥桿的左臂也用雙金屬片制成，當(dāng)環(huán)境溫度發(fā)生變化時(shí)，伊頓穆勒 ETAON 監(jiān)測(cè)繼電器EMR6-N1000-A-1，主電路中的雙金屬片會(huì)產(chǎn)生一定的變形彎曲，伊頓穆勒 ETAON 監(jiān)測(cè)繼電器EMR6-N1000-A-1，這時(shí)人字形撥桿的左臂也會(huì)發(fā)生同方向的變形彎曲，伊頓穆勒 ETAON 監(jiān)測(cè)繼電器EMR6-N1000-A-1，從而使人字形撥桿與推桿之間的距離基本保持不變，保證熱繼電器動(dòng)作的準(zhǔn)確性。這種作用稱溫度補(bǔ)償作用。 </p> <p> <br /> </p> <p>

當(dāng)執(zhí)行繼電器的繞組（感性負(fù)載）被接通和斷開時(shí)。線圈中會(huì)產(chǎn)生一連串上升速度快，頻率和幅度都相當(dāng)高的尖峰脈沖電磁振蕩輻射，對(duì)直流繼電器繞組通常采用以下方法來減少干擾： </p> <p> 在線圈兩端反并二極管或RC器件，如控制觸點(diǎn)對(duì)交流感性負(fù)載的控制，也可考慮在觸點(diǎn)并接RC器件，從而能對(duì)觸點(diǎn)在通斷時(shí)產(chǎn)生的干擾進(jìn)行有效的吸收。 </p> <p> 屏蔽 </p> <p> 屏蔽能有效地***通過空間傳播的電磁干擾，一則可限制內(nèi)部產(chǎn)生的電磁能輻射出去；二則可防止外來輻射進(jìn)入，在對(duì)內(nèi)部電子線路采用整體屏蔽措施，也可對(duì)內(nèi)部信號(hào)線采用屏蔽線，增強(qiáng)其抗干擾能力。 </p> <p> <br /> </p> <p> <br />

</p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>繼電器</strong>的可靠性（二） </p> <p> 5、溫度對(duì)繼電器可靠性的影響：繼電器工作溫度范圍在-25～70℃之間。隨著溫度的升高，繼電器的平均故障間隔時(shí)間逐漸下降。 </p> <p> 6、動(dòng)作速率對(duì)繼電器可靠性的影響：隨著繼電器動(dòng)作速率的提高，平均故障間隔時(shí)間基本呈指數(shù)型下降趨勢(shì)。因此，若設(shè)計(jì)的電路要求繼電器的動(dòng)作速率非常高，那么在電路維修時(shí)就需要仔細(xì)檢測(cè)繼電器以便及時(shí)對(duì)它更換。 </p> <p> 7、電流比對(duì)繼電器可靠性的影響：所謂電流比是繼電器的工作負(fù)載電流與額定負(fù)載電流之比。電流比對(duì)繼電器的可靠性影響很大，尤其當(dāng)電流比大于0.1時(shí)，平均故障間隔時(shí)間迅速下降，而電流比小于0.1時(shí)，平均故障間隔時(shí)間基本不變，因此在電路設(shè)計(jì)時(shí)應(yīng)選用額定電流較大的負(fù)載以降低電流比，這樣可保證繼電器乃至整個(gè)電路不因工作電流的波動(dòng)而使可靠性降低。
