2、晶閘管智能調(diào)壓模塊各功能端的控制特性均為正極性，即控制電壓越高，模塊強(qiáng)電主回路輸出電壓越高。 </p> <p> 3、晶閘管智能調(diào)壓模塊在某一時刻宜使用一種輸入控制方式，若2種以上方式同時輸入使用，則輸入信號較強(qiáng)的一種起主要作用。 </p> <p> 4、晶閘管智能調(diào)壓模塊電源為上進(jìn)下出，三相交流電路的進(jìn)線R、S、T無相序要求，導(dǎo)線粗細(xì)按實際使用電流選擇。 </p> <p> 5、晶閘管智能調(diào)壓模塊N線*為模塊內(nèi)部開關(guān)電源用，用1平方細(xì)導(dǎo)線即可，聊城MTDC150晶閘管智能模塊，N線與各輸入控制端之間為全隔離絕緣設(shè)計。 </p> <p> 6、晶閘管智能調(diào)壓模塊在使用過程中若發(fā)生過流現(xiàn)象，應(yīng)首先檢查負(fù)載有無短路等故障。可在模塊的進(jìn)線R、S、T端之前安裝快速熔斷器進(jìn)行過流保護(hù)，聊城MTDC150晶閘管智能模塊，規(guī)格可按實際負(fù)載電流的1.5倍選配。 </p> <p> 7、智能晶閘管智能調(diào)壓模塊應(yīng)與散熱器配合使用，聊城MTDC150晶閘管智能模塊，在機(jī)柜中與其他器件之間有足夠的散熱空間。必要時可安裝風(fēng)扇強(qiáng)制散熱。正高電氣為客戶服務(wù)，要做到更好。聊城MTDC150晶閘管智能模塊</p><div style="width:100%;text-align: center;"><img

以具有自關(guān)斷能力，使用方便，是理想的高壓、大電流開關(guān)器件。GTO的容量及使用壽命均超過巨型晶體管（GTR），只是工作頻紡比GTR低。目前，GTO已達(dá)到3000A、4500V的容量。大功率可關(guān)斷晶閘管已用于斬波調(diào)速、變頻調(diào)速、逆變電源等領(lǐng)域，顯示出強(qiáng)大的生命力?？申P(guān)斷晶閘管也屬于PNPN四層三端器件，其結(jié)構(gòu)及等效電路和普通晶閘管相同，因此圖1*繪出GTO典型產(chǎn)品的外形及符號。大功率GTO大都制成模塊形式。盡管GTO與SCR的觸發(fā)導(dǎo)通原理相同，但二者的關(guān)斷原理及關(guān)斷方式截然不同。這是由于普通晶閘管在導(dǎo)通之后即外于深度飽和狀態(tài)，而GTO在導(dǎo)通后只能達(dá)到臨界飽和，所以GTO門極上加負(fù)向觸發(fā)信號即可關(guān)斷。GTO的一個重要參數(shù)就是關(guān)斷增益，βoff，它等于陽極比較大可關(guān)斷電流IATM與門極比較大負(fù)向電流IGM之比，有公式βoff=IATM/IGMβoff一般為幾倍至幾十倍。βoff值愈大，說明門極電流對陽極電流的控制能力愈強(qiáng)。很顯然，βoff與昌盛的hFE參數(shù)頗有相似之處。下面分別介紹利用萬用表判定GTO電極、檢查GTO的觸發(fā)能力和關(guān)斷能力、估測關(guān)斷增益βoff的方法。1．判定GTO的電極將萬用表撥至R×1檔，測量任意兩腳間的電阻，*當(dāng)黑表筆接G極，紅表筆接K極時，電阻呈低阻值。聊城MTDC150晶閘管智能模塊公司實力雄厚，產(chǎn)品質(zhì)量可靠。</p><div

這兩部分電路，R5、RP和C5構(gòu)成阻容移相電路。合上電源開關(guān)S，交流電源電壓通過R5、RP向電容器C5充電，當(dāng)電容器C5兩端的電壓上升到略高于雙向觸發(fā)二極管ST的轉(zhuǎn)折電壓時，ST和雙向晶閘管VS相繼導(dǎo)通，負(fù)載RL得電工作。當(dāng)交流電源電壓過零瞬間，雙向晶閘管自行關(guān)斷，接著C5又被電源反向充電，重復(fù)上述過程。分析電路時，觸發(fā)電路是工作在交流電路中的，交流電壓的正、負(fù)半周分別會發(fā)出正、負(fù)觸發(fā)脈沖送到雙向晶閘管的控制極，使管子在正、負(fù)半周內(nèi)對稱地導(dǎo)通一次。改變RP的阻值，就改變了C5的充電速度，也就改變了雙向晶閘管的導(dǎo)通角，相應(yīng)地改變了負(fù)載RL上的交流電壓，實現(xiàn)了交流調(diào)壓。同是不是可以直接作交流調(diào)壓器使用呢？一個簡易型調(diào)壓器，在要求不高的場合（如燈具調(diào)光）完全可以使用。這種調(diào)壓器的缺點有兩個：一是負(fù)載RL上的電壓不能從零伏起調(diào)，比較低只能調(diào)到20V。當(dāng)RP調(diào)到比較大值時，C5充電速度變得很慢，以致在交流電壓的半個周期時間內(nèi)，C5上的電壓還來不及上升到雙向觸發(fā)二極管的轉(zhuǎn)折電壓，雙向晶閘管就不能導(dǎo)通。為了克服這一缺點，增加了由R4、C4和R6組成的另一條阻容移相電路。當(dāng)RP調(diào)到極限值以上時。C4上的電壓可經(jīng)R6向C5充電。正高電氣不斷從事技術(shù)革新，改進(jìn)生產(chǎn)工藝，提高技術(shù)水平。</p><div
