style="text-indent:25px">電磁式中間繼電器一般由鐵芯、線圈、銜鐵、觸點(diǎn)簧片等組成的。只要在線圈兩端加上一定的電壓，線圈中就會流過一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動銜鐵的動觸點(diǎn)與靜觸點(diǎn)（常開觸點(diǎn)）吸合。當(dāng)線圈斷電后，JZY-402中間繼電器，電磁的吸力也隨之消失，銜鐵就會在彈簧的反作用力返回原來的位置，使動觸點(diǎn)與原來的靜觸點(diǎn)（常閉觸點(diǎn)）釋放。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。聚仁電力根據(jù)發(fā)展需求，將電磁式繼電器改為靜態(tài)電路集成，JZY-402中間繼電器，通過模擬量采集，使之動作更準(zhǔn)確，JZY-402中間繼電器、精度更高，是老式電磁式中間繼電器更新?lián)Q代比較好的選擇。中間繼電器外殼與外露帶電端子之間用開路電壓500V的兆歐表測量，絕緣電阻應(yīng)不小于10MΩ。JZY-402中間繼電器</p><div

style="text-indent:25px">聚仁的中間繼電器可用于各種保護(hù)和自動控制裝置中，以實(shí)現(xiàn)防跳作用。其主要優(yōu)勢為電壓線圈和電流線圈均可作為啟動和保持回路，以往的老式防跳型中間繼電器只能選擇電壓線圈或者電流線圈多了一種選擇。電流、電壓啟動回路采用電子光隔啟動具有啟動功耗小、啟動電流0.25~5A通用（選擇范圍大）、輔助電源交直流通用等特點(diǎn)。其內(nèi)部采用多個進(jìn)口小型密封繼電器組成性能更穩(wěn)定，功耗低發(fā)熱小，動作時間快。是電力系統(tǒng)和自動化控制中老型電磁式DZB中間繼電器更新的理想產(chǎn)品。DZB-13CE/312帶保持中間繼電器中間繼電器用于斷路器合位監(jiān)視，跳位監(jiān)視，電源失電監(jiān)視回路中，特別適合新型的進(jìn)口開關(guān)。</p><div

style="text-indent:25px">聚仁電力建有專業(yè)的繼電器老化室，中間繼電器在出廠發(fā)貨時還需要做老化測試，主要測試項(xiàng)目有：1、動作值：繼電器動作時所需電壓值。2、觸點(diǎn)接觸電阻：觸電閉合時，兩觸頭之間的電阻值。3、機(jī)械壽命：機(jī)械部分在不損壞的情況下，繼電器反復(fù)開關(guān)動作次數(shù)。4、觸點(diǎn)接觸電壓：觸電閉合時，觸電回路中施加一定負(fù)載電流，觸點(diǎn)間電壓值。5、電壽命：繼電器驅(qū)動線圈兩端施加額定電壓，觸點(diǎn)回路中施加額定阻性負(fù)載時，每小時循環(huán)小于300次繼電器的可靠動作次數(shù)。6、絕緣耐壓：繼電器外殼與外露帶電端子之間能耐受2KV（有效值）50Hz試驗(yàn)電壓，歷時1分鐘，無擊穿或閃絡(luò)現(xiàn)象。7、絕緣電阻：繼電器外殼與外露帶電端子之間用開路電壓500V的兆歐表測量，絕緣電阻不小于100MΩ。達(dá)到以上相關(guān)老化測試后才能出庫發(fā)貨，出貨率和合格率較高。</p><p style="text-indent:25px">傳統(tǒng)的老式中間繼電器的整體結(jié)構(gòu)是由中間機(jī)構(gòu)、承受機(jī)構(gòu)以及執(zhí)行機(jī)構(gòu)等這三個重要部分組成。其中承受機(jī)構(gòu)的作用就是為了能夠精確的反映出繼電器自身的輸入量，同時并傳遞到中間機(jī)構(gòu)中和提前設(shè)定的量（也就是整定值）讓兩個數(shù)值相互做出對比，在這個過程中要是檢測出達(dá)到了整定值時（過量或者欠量）則中間機(jī)構(gòu)就會促使執(zhí)行機(jī)構(gòu)進(jìn)行動作，將其的觸點(diǎn)閉合以及斷開從而實(shí)現(xiàn)了某一種設(shè)備控制的目的。而電磁式中間繼電器其中間機(jī)構(gòu)采用電磁式設(shè)計，有時候反映的輸入量不準(zhǔn)確，而執(zhí)行機(jī)構(gòu)采用線圈操作，由于線圈的匝數(shù)是采用從工制作，有時數(shù)量會不一樣，從而導(dǎo)致閉合或斷開的時間不準(zhǔn)確。而聚仁電力采用靜態(tài)電路的中間繼電器，其中間機(jī)構(gòu)采用芯片控制，而執(zhí)行機(jī)構(gòu)采用電路模擬判斷，在處理上和判斷上比電磁式更準(zhǔn)確。靜態(tài)集成電路的中間繼電器是通過電路原理，內(nèi)含芯片的邏輯判斷，是替換老式電磁式中間繼電器的理想產(chǎn)品。</p><div

style="text-indent:25px">中間型的繼電器用于各種保護(hù)和自動控制線路中作為輔助繼電器，以增加接點(diǎn)的數(shù)量及接點(diǎn)容量。主要實(shí)現(xiàn)以下作用：1、隔離：控制系統(tǒng)的輸出信號與負(fù)載端電氣隔離。2、轉(zhuǎn)換：比如控制系統(tǒng)輸出信號為DC24V，但負(fù)載使用AC220V供電，對于輸入可逆。3、放大：控制器輸出的信號的帶負(fù)載的能力往往有限，在mA或者數(shù)A的級別，如果有需要更大電流的負(fù)載，只能通過中間型繼電器來轉(zhuǎn)換。4、便于維護(hù)：即使是滿足負(fù)載電流要求的輸出端，但因?yàn)榧稍诳刂破鲀?nèi)部，如果損壞，更換維修比較麻煩，但如果通過中間繼電器，輸出端的負(fù)載只是繼電器的線圈，減輕了控制器輸出級的負(fù)載，從而降低損壞的幾率。而當(dāng)中間繼電器觸點(diǎn)因?yàn)轭l繁的使用損壞時，采用插拔式接線端子的中間繼電器就能很容易通過簡單的插拔完成更換。中間繼電器常用來傳遞信號和同時控制多個電路，也可用來直接控制小容量電動機(jī)或其他電氣執(zhí)行元件。DZ-54中間繼電器</p><p
