①額定工作電壓:是指繼電器正常工作時(shí)線圈所需要的電壓。根據(jù)繼電器的型號不同可以是交流電壓，也可以是直流電壓。 </p> <p> ②直流電阻:是指繼電器中線圈的直流電阻，可以通過萬用表測量。 </p> <p> ③吸合電流:是指繼電器能夠產(chǎn)生吸合動作的**小電流。在正常使用時(shí)，給定的電流必須略大于吸合電流，這樣繼電器才能穩(wěn)定地工作。而對于線圈所加的工作電壓，一般不要超過額定工作電壓的1.5倍，否則會產(chǎn)生較大的電流而把線圈燒毀。 </p> <p> ④釋放電流:是指繼電器產(chǎn)生釋放動作的比較大電流。當(dāng)繼電器吸合狀態(tài)的電流減小到定程度時(shí)，繼電器就會恢復(fù)到未通電的釋放狀態(tài)，這時(shí)的電流遠(yuǎn)遠(yuǎn)小于吸合電流。 </p> <p> ⑤觸點(diǎn)切換電壓和電流:是指繼電器允許加載的電壓和電流。它決定了繼電器能控制電壓和電流的大小，使用時(shí)不能超過此值，否則很容易損壞繼電器的觸點(diǎn)。 </p> <p> <br /> </p> <p> <br /> 溫州時(shí)間繼電器采購繼電器主要的功能有哪些？</p><div style="width:100%;text-align: center;"><img

/> </p> <p> <strong>繼電器</strong>的符號表示方法（二） </p> <p> 繼電器的觸點(diǎn)有3種基本形式： </p> <p> (1)動合型（常開，H型）線圈不通電時(shí)兩觸點(diǎn)是斷開的，通電后兩個觸點(diǎn)閉合。以“合”字的拼音字頭“H”表示。 </p> <p> (2)動斷型（常閉，D型）線圈不通電時(shí)兩觸點(diǎn)是閉合的，通電后兩個觸點(diǎn)斷開。用“斷”字的拼音字頭“D”表示。 </p> <p> (3)轉(zhuǎn)換型(Z型)是觸點(diǎn)組型。這種觸點(diǎn)組共有3個觸點(diǎn)，即中間是動觸點(diǎn)，上下各一個靜觸點(diǎn)。線圈不通電時(shí)，動觸點(diǎn)和其中一個靜觸點(diǎn)斷開，和另一個閉合；線圈通電后，動觸點(diǎn)就移動，使原來斷開的呈閉合狀態(tài)，原來閉合的呈斷開狀態(tài)，達(dá)到轉(zhuǎn)換的目的。這樣的觸點(diǎn)組稱為轉(zhuǎn)換觸點(diǎn)。用“轉(zhuǎn)”字的拼音字頭“Z”表示。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 在18世紀(jì)的時(shí)候，科學(xué)家們還認(rèn)為電和磁是風(fēng)馬牛不相及的兩種物理現(xiàn)象。1820年丹麥物理學(xué)家奧斯特發(fā)現(xiàn)電流的磁效應(yīng)后，1831年英國物理學(xué)家法拉第又發(fā)現(xiàn)了電磁感應(yīng)現(xiàn)象。這些發(fā)現(xiàn)證實(shí)了電能和磁能可以相互轉(zhuǎn)化，這也為后來的電動機(jī)和發(fā)電機(jī)的誕生奠定了基礎(chǔ)；人類則因這些發(fā)明創(chuàng)造從此邁入電氣時(shí)代。19世紀(jì)30年代，美國物理學(xué)家約瑟夫·亨利在研究電路控制時(shí)利用電磁感應(yīng)現(xiàn)象發(fā)明了<strong>繼電器</strong>。**早的繼電器是電磁繼電器，它利用電磁鐵在通電和斷電下磁力產(chǎn)生和消失的現(xiàn)象，來控制高電壓高電流的另一電路的開合，它的出現(xiàn)使得電路的遠(yuǎn)程控制和保護(hù)等工作得以順利進(jìn)行。繼電器是人類科技史上的一項(xiàng)偉大發(fā)明創(chuàng)造，它不僅是電氣工程的基礎(chǔ)，也是電子技術(shù)、微電子技術(shù)的重要基礎(chǔ)。

螺釘8是常閉觸頭復(fù)位方式調(diào)節(jié)螺釘。當(dāng)螺釘位置靠左時(shí)，電動機(jī)過載后，常閉觸頭斷開，電動機(jī)停車后，熱繼電器雙金屬片冷卻復(fù)位。常閉觸頭的動觸頭在彈簧的作用下會自動復(fù)位。此時(shí)熱繼電器為自動復(fù)位狀態(tài)。將螺釘逆時(shí)針旋轉(zhuǎn)向右調(diào)到一定位置時(shí)，若這時(shí)電動機(jī)過載，熱繼電器的常閉觸頭斷開。其動觸頭將擺到右側(cè)一新的平衡位置。電動機(jī)斷電停車后，動觸頭不能復(fù)位。必須按動復(fù)位按鈕后動觸頭方能復(fù)位。此時(shí)熱繼電器為手動復(fù)位狀態(tài)。若電動機(jī)過載是故障性的，為了避免再次輕易地起動電動機(jī)，熱繼電器宜采用手動復(fù)位方式。若要將熱繼電器由手動復(fù)位方式調(diào)至自動復(fù)位方式，只需將復(fù)位調(diào)節(jié)螺釘順時(shí)針旋進(jìn)至適當(dāng)位置即可。
