磁保持繼電器是一種雙穩(wěn)態(tài)繼電器，分單線圈結(jié)構(gòu)和雙線圈結(jié)構(gòu)，線圈激勵(lì)為電脈沖方式。對單線圈結(jié)構(gòu)繼電器，當(dāng)線圈在規(guī)定的電壓激勵(lì)量作用下其觸點(diǎn)輸出狀態(tài)改變，線圈激勵(lì)撤銷后，觸點(diǎn)能保持已有狀態(tài)，要改變觸點(diǎn)輸出狀態(tài)，需對線圈加一規(guī)定的反向電壓激勵(lì)量。對雙線圈結(jié)構(gòu)繼電器，當(dāng)***線圈在規(guī)定的電壓激勵(lì)量作用下其觸點(diǎn)輸出狀態(tài)改變，線圈激勵(lì)撤銷后，觸點(diǎn)能保持已有狀態(tài)，要改變觸點(diǎn)輸出狀態(tài)，需對第二線圈加規(guī)定的電壓激勵(lì)量。 </p> <p> 由于新型繼電器具有的特殊性能，它的檢測方法和檢測要求也不同于常規(guī)繼電器的檢測。主要檢測的內(nèi)容有電氣參數(shù)檢測、電氣性能指標(biāo)檢測、機(jī)械性能指標(biāo)檢測和物理性能指標(biāo)檢測等。 </p> <p> <br /> </p> <p> <br />

使用熱繼電器對電動(dòng)機(jī)進(jìn)行過載保護(hù)時(shí)，將熱元件與電動(dòng)機(jī)的定子繞組串聯(lián)，將熱繼電器的常閉觸頭串聯(lián)在交流接觸器的電磁線圈的控制電路中，并調(diào)節(jié)整定電流調(diào)節(jié)旋鈕，使人字形撥桿與推桿相距一適當(dāng)距離。當(dāng)電動(dòng)機(jī)正常工作時(shí)，通過熱元件的電流即為電動(dòng)機(jī)的額定電流，熱元件發(fā)熱，雙金屬片受熱后彎曲，使推桿剛好與人字形撥桿接觸，而又不能推動(dòng)人字形撥桿。常閉觸頭處于閉合狀態(tài)，交流接觸器保持吸合，電動(dòng)機(jī)正常運(yùn)行。 </p> <p> <br /> </p> <p> <br /> </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。

<strong>繼電器</strong>的測試（二） </p> <p> 近兩年來，國家電網(wǎng)逐步規(guī)范了電表技術(shù)要求，制定相關(guān)行業(yè)標(biāo)準(zhǔn)以及技術(shù)規(guī)范，這為繼電器參數(shù)檢測提出了一些技術(shù)難題，如繼電器的負(fù)載通斷能力、開關(guān)特性測試等。因此，迫切需要研究一種設(shè)備，實(shí)現(xiàn)繼電器性能參數(shù)的綜合檢測。 </p> <p> 根據(jù)繼電器性能參數(shù)測試要求，測試項(xiàng)目可以分為兩大類，一是不帶負(fù)載電流的測試項(xiàng)目，如動(dòng)作值、觸點(diǎn)接觸電阻、機(jī)械壽命；二是帶負(fù)載電流的測試項(xiàng)目，如觸點(diǎn)接觸電壓、電壽命、過負(fù)荷能力。 </p> <p> <br /> </p> <p> <br />
