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。

熱繼電器主要用于保護(hù)電動(dòng)機(jī)的過載，因此選用時(shí)必須了解電動(dòng)機(jī)的情況，如工作環(huán)境、啟動(dòng)電流、負(fù)載性質(zhì)、工作制、允許過載能力等。 </p> <p> 1、原則上應(yīng)使熱繼電器的安秒特性盡可能接近甚至重合電動(dòng)機(jī)的過載特性，或者在電動(dòng)機(jī)的過載特性之下，同時(shí)在電動(dòng)機(jī)短時(shí)過載和啟動(dòng)的瞬間，熱繼電器應(yīng)不受影響(不動(dòng)作)。 </p> <p> 2、當(dāng)熱繼電器用于保護(hù)長(zhǎng)期工作制或間斷長(zhǎng)期工作制的電動(dòng)機(jī)時(shí)，一般按電動(dòng)機(jī)的額定電流來選用。例如，熱繼電器的整定值可等于0.95~1.05倍的電動(dòng)機(jī)的額定電流，或者取熱繼電器整定電流的中值等于電動(dòng)機(jī)的額定電流，然后進(jìn)行調(diào)整。 </p> <p> 3、當(dāng)熱繼電器用于保護(hù)反復(fù)短時(shí)工作制的電動(dòng)機(jī)時(shí)，熱繼電器*有一定范圍的適應(yīng)性。如果短時(shí)間內(nèi)操作次數(shù)很多，就要選用帶速飽和電流互感器的熱繼電器。 </p> <p> 4、對(duì)于正反轉(zhuǎn)和通斷頻繁的特殊工作制電動(dòng)機(jī)，不宜采用熱繼電器作為過載保護(hù)裝置，而應(yīng)使用埋入電動(dòng)機(jī)繞組的溫度繼電器或熱敏電阻來保護(hù)。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 振蕩器參數(shù)設(shè)置（六） </p> <p> K3為工作模式選擇，當(dāng)K3接通時(shí)，時(shí)間繼電器的工作模式為間隔定時(shí)，也就是當(dāng)時(shí)間繼電器接通工作電源后，芯片OUT輸出端先輸出高電平，致使內(nèi)部執(zhí)行繼電器工作，待所設(shè)定的延時(shí)到達(dá)后OUT無高電平輸出，執(zhí)行繼電器釋放；如K3不接通，時(shí)間繼電器為常規(guī)的通電延時(shí)型，工作狀態(tài)與間隔定時(shí)相反。 </p> <p> 總之，針對(duì)時(shí)間繼電器的工作特點(diǎn)而研制的時(shí)間**芯片有其多時(shí)基選擇、時(shí)間預(yù)置方便、顯示直觀、時(shí)間整定誤差小等優(yōu)點(diǎn)，是常規(guī)的CMOS計(jì)數(shù)分頻集成電路無法來實(shí)現(xiàn)的。 </p> <p> <br /> </p> <p> <br />
