③測(cè)量吸合電壓和吸合電流：用可調(diào)穩(wěn)壓電源和電流表，給繼電器輸入一組電壓，且在供電回路中串入電流表進(jìn)行監(jiān)測(cè)。慢慢調(diào)高電源電壓，聽到繼電器吸合的聲音時(shí)，記錄吸合電壓和吸合電流。為求準(zhǔn)確，可以嘗試多次求平均值。 </p> <p> ④測(cè)量釋放電壓和釋放電流:也是像上述那樣連接測(cè)試，當(dāng)繼電器發(fā)生吸合后，再逐漸降低供電電壓，當(dāng)聽到繼電器再次發(fā)生釋放聲音時(shí)，記下此時(shí)的電壓和電流，亦可嘗試多次而取得平均的釋放電壓和釋放電流。一般情況下，繼電器的釋放電壓為吸合電壓的10%~50%如果釋放電壓大小(小于1/10的吸合電壓)，則不能正常使用，這樣會(huì)對(duì)電路的穩(wěn)定性造成威脅，使工作不可靠。

繼電器線圈在電路中用一個(gè)長(zhǎng)方框符號(hào)表示，如果繼電器有兩個(gè)線圈，就畫兩個(gè)并列的長(zhǎng)方框。同時(shí)在長(zhǎng)方框內(nèi)或長(zhǎng)方框旁標(biāo)上繼電器的文字符號(hào)“J”。繼電器的觸點(diǎn)有兩種表示方法：一種是把它們直接畫在長(zhǎng)方框一側(cè)，這種表示法較為直觀。另一種是按照電路連接的需要，把各個(gè)觸點(diǎn)分別畫到各自的控制電路中，通常在同一繼電器的觸點(diǎn)與線圈旁分別標(biāo)注上相同的文字符號(hào)，并將觸點(diǎn)組編上號(hào)碼，以示區(qū)別。繼電器的觸點(diǎn)一共有有3種基本形式。

4.轉(zhuǎn)換接點(diǎn)類型，在工業(yè)控制線路中，常常會(huì)出現(xiàn)這樣的情況，控制要求需要使用接觸器的常閉接點(diǎn)才能達(dá)到控制目的，但是接觸器本身所帶的常閉接點(diǎn)已經(jīng)用完，無法完成控制任務(wù)。這時(shí)可以將一個(gè)中間繼電器與原來的接觸器線圈并聯(lián)，用中間繼電器的常閉接點(diǎn)去控制相應(yīng)的元件，轉(zhuǎn)換一下接點(diǎn)類型，達(dá)到所需要的控制目的。 </p> <p> 5.用作開關(guān)，在一些控制線路中，一些電器元件的通斷常常使用中間繼電器，用其接點(diǎn)的開閉來控制，例如如彩電或顯示器中常見的自動(dòng)消磁電路，三極管控制中間繼電器的通斷，從而達(dá)到控制消磁線圈通斷的作用。 </p> <p> <br /> </p> <p> <br /> 按繼電器的負(fù)載的分類。嘉興品牌繼電器經(jīng)銷商</p><p style="text-indent:25px">時(shí)間繼電器的作用是什么？嘉興品牌繼電器經(jīng)銷商</p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <strong>中間繼電器</strong>的作用（一） </p> <p> 1.代替小型接觸器，中間繼電器的觸點(diǎn)具有一定的帶負(fù)荷能力，當(dāng)負(fù)載容量比較小時(shí)，可以用來替代小型接觸器使用，比如電動(dòng)卷閘門和一些小家電的控制。這樣的優(yōu)點(diǎn)是不僅可以起到控制的目的，而且可以節(jié)省空間，使電器的控制部分做得比較精致。 </p> <p> 2.增加接點(diǎn)數(shù)量，這是中間繼電器**常見的用法，例如，在電路控制系統(tǒng)中一個(gè)接觸器的接點(diǎn)需要控制多個(gè)接觸器或其他元件時(shí)而是在線路中增加一個(gè)中間繼電器。 </p> <p> 3.增加接點(diǎn)容量，我們知道，中間繼電器的接點(diǎn)容量雖然不是很大，但也具有一定的帶負(fù)載能力，同時(shí)其驅(qū)動(dòng)所需要的電流又很小，因此可以用中間繼電器來擴(kuò)大接點(diǎn)容量。比如一般不能直接用感應(yīng)開關(guān)、三極管的輸出去控制負(fù)載比較大的電器元件。而是在控制線路中使用中間繼電器，通過中間繼電器來控制其他負(fù)載，達(dá)到擴(kuò)大控制容量的目的。
