單向晶閘管模塊具有其獨(dú)特的特性：當(dāng)陽極連接到反向電壓時(shí)，或陽極連接到正向電壓時(shí)，但控制極不增加電壓，則不會(huì)導(dǎo)通，當(dāng)陽極和控制極同時(shí)連接到正向電壓時(shí)，將變?yōu)榻油顟B(tài)，青島雙向可控硅模塊品牌。一旦接通，控制電壓將失去控制作用。無論有無控制電壓，無論控制電壓的極性如何，都將始終處于接通狀態(tài)。若要關(guān)閉，只能將陽極電壓降到某個(gè)臨界值或反向。

一種以硅單晶為基本材料的P1N1P2N2四層三端器件，創(chuàng)制于1957年，由于它特性類似于真空閘流管，所以國際上通稱為硅晶體閘流管，簡(jiǎn)稱晶閘管T。又由于晶閘管開始應(yīng)用于可控整流方面所以又稱為硅可控整流元件，簡(jiǎn)稱為可控硅SCR。 </p> <p> 在性能上，可控硅不僅具有單向?qū)щ娦裕疫€具有比硅整流元件(俗稱“死硅”)更為可貴的可控性。它只有導(dǎo)通和關(guān)斷兩種狀態(tài)。 </p> <p> 可控硅能以毫安級(jí)電流控制大功率的機(jī)電設(shè)備，如果超過此頻率，因元件開關(guān)損耗明顯增加，允許通過的平均電流相降低，此時(shí)，標(biāo)稱電流應(yīng)降級(jí)使用。 </p> <p> 可控硅的優(yōu)點(diǎn)很多，例如：以小功率控制大功率，功率放大倍數(shù)高達(dá)幾十萬倍;反應(yīng)極快，在微秒級(jí)內(nèi)開通、關(guān)斷;無觸點(diǎn)運(yùn)行，無火花、無噪音;效率高，成本低等等。 </p> <p> 可控硅的弱點(diǎn)：靜態(tài)及動(dòng)態(tài)的過載能力較差;容易受干擾而誤導(dǎo)通。 </p> <p> 可控硅從外形上分類主要有：螺栓形、平板形和平底形。 </p><p> 可控硅模塊特點(diǎn)： </p> <p> 1 對(duì)耐壓級(jí)別的選擇：通常把VDRM(斷態(tài)重復(fù)峰值電壓)和VRRM(反向重復(fù)峰值電壓)中較小的值標(biāo)作該器件的額定電壓。 </p> <p> 2 對(duì)電流的確定：由于雙向可控硅模塊通常用在交流電路中，因此不能用平均值而用有效值來表示它的額定電流值。由于可控硅的過載能力比一般電磁器件小，因而一般家電中選用可控硅模塊的電流值為實(shí)際工作電流值的2~3倍。同時(shí)，可控硅承受斷態(tài)重復(fù)峰值電壓VDRM和反向重復(fù)峰值電壓VRRM 時(shí)的峰值電流應(yīng)小于器件規(guī)定的IDRM和IRRM。 </p> <p> 3 對(duì)通態(tài)電壓VTM的選擇：它是可控硅模塊通以規(guī)定倍數(shù)額定電流時(shí)的瞬態(tài)峰值壓降。為了減少可控硅的熱損耗，應(yīng)盡可能選擇VTM小的可控硅。 </p> <p> 4 對(duì)維持電流：IH是維持可控硅模塊保持通態(tài)所必需的極小主電流，它與結(jié)溫有關(guān)，結(jié)溫越高，則IH越小。 </p> <p> 5 對(duì)電壓上升率的：dv/dt指的是在關(guān)斷狀態(tài)下電壓的上升斜率，這是防止誤觸發(fā)的一個(gè)關(guān)鍵參數(shù)。由于雙向可控硅模塊的制造工藝決定了A2與G之間會(huì)存在寄生電容。淄博正高電氣有限公司得到市場(chǎng)的一致認(rèn)可。</p><div style="width:100%;text-align: center;"><img

可控硅模塊散熱條件的好壞直接關(guān)系到商品的運(yùn)用壽數(shù)和短時(shí)過載才華，溫度越低模塊的輸出電流越大，所以在運(yùn)用中有必要裝備散熱器和風(fēng)機(jī)，主張選用帶有過熱維護(hù)功用的商品，有水冷散熱條件的優(yōu)先挑選水冷散熱。咱們經(jīng)過嚴(yán)肅測(cè)算，斷定了不一樣類型的商品所大概裝備的散熱器類型，推薦選用廠家配套的散熱器和風(fēng)機(jī)，用戶自備時(shí)按以下準(zhǔn)則挑選： </p> <p> 1、軸流風(fēng)機(jī)的風(fēng)速應(yīng)大于6m/s ； </p> <p> 2、有必要能確保模塊正常作業(yè)時(shí)散熱底板溫度不大于80℃； </p> <p> 3、模塊負(fù)載較輕時(shí)，可減小散熱器的大小或選用天然冷卻； </p> <p>

style="text-indent:25px">淄博正高電氣有限公司產(chǎn)品**國內(nèi)。青島雙向可控硅模塊品牌</p><p> 雙向可控硅晶閘管使用中，應(yīng)特別注意以下事項(xiàng)： </p> <p> <br /> </p> <p> 1.靈敏度 </p> <p> 雙向可控硅是一個(gè)三端元件，但我們不再稱其兩極為陰陽極，而是稱作T1和T2極，G為控制極，其控制極上所加電壓無論為正向觸發(fā)脈沖或負(fù)向觸發(fā)脈沖均可使控制極導(dǎo)通，但是觸發(fā)靈敏度互不相同，即保證雙向可控硅能進(jìn)入導(dǎo)通狀態(tài)的較小門極電流IGT是有區(qū)別的。 </p> <p> 2.可控硅過載的保護(hù) </p> <p> 可控硅元件優(yōu)點(diǎn)很多，但是它過載能力差，短時(shí)間的過流，過壓都會(huì)造成元件損壞，因此為保證元件正常工作，需有條件： </p> <p> （1）外加電壓下允許超過正向轉(zhuǎn)折電壓，否則控制極將不起作用； </p> <p> （2）可控硅的通態(tài)平均電流從安全角度考慮一般按較大電流的1.5~2倍來取； </p> <p> （3）為保證控制極可靠觸發(fā)，加到控制極的觸發(fā)電流一般取大于其額值，除此以外，還必須采取保護(hù)措施，一般對(duì)過流的保護(hù)措施是在電路中串入快速熔斷器，其額定電流取可控硅電流平均值的1.5倍左右，其接入的位置可在交流側(cè)或直流側(cè)，當(dāng)在交流側(cè)時(shí)額定電流取大些，一般多采用前者，過電壓保護(hù)常發(fā)生在存在電感的電路上，或交流側(cè)出現(xiàn)干擾的浪涌電壓或交流側(cè)的暫態(tài)過程產(chǎn)生的過壓。由于，過電壓的尖峰高，作用時(shí)間短，常采用電阻和電容吸收電路加以。
