時間繼電器的知識：繼電器是科技社會不可缺少的零件，同時根據(jù)不同環(huán)境的需求也有很多種類型的繼電器，時間繼電器是比較常見的一種，下面青島明志創(chuàng)新就給大家來簡單介紹一下。時間繼電器屬于一種延時繼電器，因此也被叫做延時時間繼電器，其作用就是繼電器通電后，對應(yīng)的觸電匯延時一定的時間在接通或斷開，淄博整流橋模塊價格，也分為通電延時型和斷電延時型兩類。時間繼電器啟動方式有機(jī)械式和電子式兩種。機(jī)械式的是啟動后電磁鐵受所帶氣囊排氣時間限制而實(shí)現(xiàn)定時工作，淄博整流橋模塊價格，電子式是通過電容從放點(diǎn)過程，控制延時時間。另一種時間繼電器是指定啟動時刻，利用時鐘達(dá)到指定時刻來控制繼電器接通或斷開，他們也分機(jī)械式及電子式。所有的時間繼電器都是提供相應(yīng)的開關(guān)，需要有時間繼電器控制的電器電源，通過時間繼電器提供的開關(guān)，在接到電器上，淄博整流橋模塊價格。時間繼電器有自己的電源，當(dāng)啟動時間繼電器后，所接電器變由時間繼電器來控制它的通斷了。固態(tài)繼電器(SolidStateRelay，縮寫SSR)，是由微電子電路，分立電子器件，電力電子功率器件組成的無觸點(diǎn)開關(guān)。用隔離器件實(shí)現(xiàn)了控制端與負(fù)載端的隔離。固態(tài)繼電器的輸入端用微小的控制信號，達(dá)到直接驅(qū)動大電流負(fù)載。地理位置優(yōu)越，交通十分便利。淄博整流橋模塊價格</p><div

感性負(fù)載還具有較高的反電勢。這是一個不定值，隨L和di/dt的不同而不同。通常為電源電壓的1—2倍，這樣和電源電壓疊加。有高達(dá)三倍的電源電壓。容性負(fù)載具有更大的危險性，因?yàn)槠饎訒r，由于電容器兩端的電壓不能突變，電容器（負(fù)載）相當(dāng)于短路。這種負(fù)載在選型時更要特別注意。需要特別指出的是用戶不要將SSR的浪涌電流值作為選擇負(fù)載起動電流的依據(jù)。SSR的浪涌電流值是以晶閘管浪涌電流為標(biāo)準(zhǔn)的。它的前提條件是半個（或一個）電源周波。即10或20ms。而前述啟動過程，少則幾百毫秒、幾分鐘，多則高達(dá)10分鐘。這點(diǎn)務(wù)必敬請高度注意。選型方法1.在選用小電流規(guī)格印刷電路板使用的固態(tài)繼電器時，因引線端子為高導(dǎo)熱材料制成,焊接時應(yīng)在溫度小于250℃、時間小于10S的條件下進(jìn)行，如考慮周圍溫度的原因，必要時可考慮降額使用，一般將負(fù)載電流控制在額定值的1/2以內(nèi)使用。[2]2.各種負(fù)載浪涌特性對固態(tài)繼電器SSR的選擇被控負(fù)載在接通瞬間會產(chǎn)生很大的浪涌電流，由于熱量來不及散發(fā)，很可能使SSR內(nèi)部可控硅損壞,所以用戶在選用繼電器時應(yīng)對被控負(fù)載的浪涌特性進(jìn)行分析,然后再選擇繼電器。使繼電器在保證穩(wěn)態(tài)工作前提下能夠承受這個浪涌電流。淄博整流橋模塊價格淄博正高電氣銳意進(jìn)取，持續(xù)創(chuàng)新為各行各業(yè)提供專業(yè)化服務(wù)。</p><div

固態(tài)繼電器使用壽命長，可靠性強(qiáng)。固態(tài)繼電器對應(yīng)的是cdg1系列美味。這種固態(tài)繼電器沒有機(jī)械部件和固態(tài)器件來完成接觸功能。由于零件不運(yùn)動，所以可以在高沖擊和振動環(huán)境下工作。由于構(gòu)成固態(tài)繼電器元件的固有特性，決定了固態(tài)繼電器的性能。使用壽命長，可靠性高。交流接觸器通過線棒控制磁鐵的吸力，使觸頭接觸或斷開，使觸頭長期燒壞。固態(tài)繼電器具有靈敏度高、控制功率低、電磁兼容性好等優(yōu)點(diǎn)。固態(tài)繼電器輸入電壓范圍寬，驅(qū)動功率低。它可以兼容大多數(shù)邏輯集成電路，無需緩沖器或驅(qū)動器。固態(tài)繼電器的快速轉(zhuǎn)換。固態(tài)繼電器可以從毫秒切換到微妙的，因?yàn)楣虘B(tài)。切換的速度非常快。交流接觸器的開關(guān)速度由線圈控制，因此開關(guān)速度在零位時為幾秒，比固態(tài)繼電器慢。固態(tài)繼電器電磁干擾小。因?yàn)楣虘B(tài)繼電器沒有輸入線圈，沒有接觸電弧和回彈，從而減少了電磁干擾。大多數(shù)交流輸出固態(tài)繼電器都是零電壓開關(guān)，在零電壓時接通，在零電流時斷開，從而減少電流波形的突然中斷，從而降低開關(guān)的暫態(tài)效應(yīng)。相應(yīng)接觸器的電磁干擾較大。固態(tài)繼電器體積小，接觸器大。在一些空間相對狹窄的地方，安裝接觸器可能不方便，因此需要固態(tài)繼電器；但是。</p><p> 380V選用MYH12-750V壓敏電阻；較大容量的電機(jī)變壓器應(yīng)選用MYH20或MYH2024通流容量大的壓敏電阻。選用原則是220V選用500V-600V壓敏電阻，380V時可選用800V-900V壓敏電阻。調(diào)壓應(yīng)用SSR，TSR調(diào)壓型模塊，可采用外配模擬量信號來觸發(fā)模塊就可實(shí)現(xiàn)線性可調(diào)輸出電壓。例如，PLC或控溫儀輸出模擬量信號：1-5V，4-20mA的觸發(fā)系統(tǒng)。國產(chǎn)單相三相可控硅觸發(fā)板，配合可控硅，也可以外配模擬量信號來調(diào)節(jié)觸發(fā)板，觸發(fā)板再觸發(fā)模塊就可實(shí)現(xiàn)線性可調(diào)輸出電壓，控制可控硅導(dǎo)通角，以達(dá)到調(diào)壓之目的。交流調(diào)功“交流調(diào)功”是一種Z型SSR普遍采用的方法，也能實(shí)現(xiàn)PID調(diào)節(jié)。即在固定周期內(nèi)，控制交流正弦電流半波個數(shù)，達(dá)到調(diào)功目的。模擬電路常采用電壓比較器，將一個固定周期的鋸齒電壓和來自前級誤差電壓作比較，輸出方波實(shí)現(xiàn)調(diào)節(jié)，如圖3所示。在計(jì)算機(jī)上采用計(jì)時算法，產(chǎn)生占空比可調(diào)的方波脈沖擊來實(shí)現(xiàn)。例如日本的SHIMADEW和OMRON公司的SR22、FD20、E5系列智能化控溫產(chǎn)品，配合Z型SSR，實(shí)現(xiàn)自適應(yīng)“自動翻轉(zhuǎn)”控制，即通過計(jì)算機(jī)產(chǎn)生擾動，算出佳PID控制參數(shù)。三相電流HS系列SSR產(chǎn)品，可直接用于三相電機(jī)的控制。簡單的方法，是采用2只SSR作電機(jī)通斷控制，4只SSR作電機(jī)換相控制。淄博正高電氣為客戶提供更科學(xué)、更經(jīng)濟(jì)、更多面的售后服務(wù)。</p><div

并考慮涂適量導(dǎo)熱硅脂以達(dá)到佳散熱效果。如繼電器長期工作在高溫狀態(tài)下（40℃~80℃）時，用戶可根據(jù)廠家提供的大輸出電流與環(huán)境溫度曲線數(shù)據(jù)，考慮降額使用來保證正常工作。固態(tài)繼電器發(fā)熱原因：固態(tài)繼電器即在正常工作的時候，在其內(nèi)部芯片上存在一定的功率損耗，這個損耗功率主要由固態(tài)繼電器輸出電壓降與負(fù)載電流乘積決定，以發(fā)熱的形式消耗掉。因此散熱的好壞直接影響到固態(tài)繼電器工作的可靠性，優(yōu)良的熱學(xué)設(shè)計(jì)可避免由于散熱不良造成的失敗和損壞。過流過壓在繼電器使用時，因過流和負(fù)載短路會造成SSR固態(tài)繼電器內(nèi)部輸出可控硅長久損壞，可考慮在控制回路中增加快速熔斷器和空氣開關(guān)予以保護(hù)型（選擇繼電器應(yīng)選擇產(chǎn)品輸出保護(hù)，內(nèi)置壓敏電阻吸收回路和RC緩沖器，可吸收浪涌電壓和提高dv/dt耐量）；快速熔斷器和空氣開關(guān)，是通用的過電流保護(hù)方法?？焖偃蹟嗥骺砂搭~定工作電流的，一般小容量可選用保險絲。特別注意負(fù)載短路，是造成SSR產(chǎn)品損壞的主要原因。感性及容性負(fù)載，除內(nèi)部RC電路保護(hù)外，建議采用壓敏電阻并聯(lián)在輸出端，作為組合保護(hù)。金屬氧化鋅壓敏電阻（MOV）面積大小決定吸收功率，厚度決定保護(hù)電壓值。交流220V的SSR，選用MYH12-430V的壓敏電阻。淄博正高電氣降低客戶風(fēng)險才是能夠良好合作的開始。淄博整流橋模塊價格</p><p

控制大電流、大功率場合不如后者，控制動作瀕繁的電路時，壽命不如后者長?？傊?，傳統(tǒng)繼電器與固態(tài)繼電器的對比各有千秋，后者因其工作可靠，無觸點(diǎn)、無火花、壽命長、無噪聲，無電磁干擾，開關(guān)速度快，越來越受到歡迎。固態(tài)繼電器（SSR）是一種新型繼電器，它全部采用電子器件構(gòu)成，實(shí)際上是一種無觸點(diǎn)電子開關(guān)。固態(tài)繼電器自問世以來發(fā)展很快，各類也較多。產(chǎn)品介紹：用途：普遍用于溫控，光控，復(fù)合開關(guān)及各種非絕緣交流開關(guān)等場合特點(diǎn)：（1）過零觸發(fā)：控制電源電壓范圍寬（5—32VDC）（2）采用進(jìn)口方形芯片，高級芯片支撐板，經(jīng)特殊焊接工藝，保證焊接層無空洞，使用更可靠（3）采用DCB板及其他高級導(dǎo)熱絕緣材料，導(dǎo)熱性能好，導(dǎo)熱底板不帶電，保證使用安全（4）采用高級封裝材料，防暴，防潮性能更佳，外觀更漂亮（5）熱循環(huán)負(fù)載次數(shù)高于國家標(biāo)準(zhǔn)近10倍，使用壽命長固態(tài)繼電器安裝要求：根據(jù)散熱器結(jié)構(gòu)把風(fēng)機(jī)固定在散熱器上在固態(tài)繼電器的導(dǎo)熱底板表面和散熱器表面都均勻涂覆一層導(dǎo)熱硅脂，再用4個螺釘把固態(tài)繼電器固定于散熱器上。注意4個螺釘用力要均等，以免拉裂塑料外殼用接線端頭環(huán)帶將電纜銅線扎緊，好再浸錫，以免接觸不良而附加發(fā)熱，然后套上絕緣熱縮管。淄博整流橋模塊價格</p><p
