而且VBO和VRB值隨電壓的重復(fù)施加而變小。在感性負(fù)載的情況下，如磁選設(shè)備的整流裝置。在關(guān)斷的時(shí)候會(huì)產(chǎn)生很高的電壓（∈=-Ldi/dt），假如電路上未有良好的吸收回路，此電壓將會(huì)損壞晶閘管模塊。因此，晶閘管模塊也必須有足夠的反向耐壓VRRM。晶閘管模塊在變流器（如電機(jī)車）中工作時(shí)，必須能夠以電源頻率重復(fù)地經(jīng)受一定的過電壓而不影響其工作，所以正反向峰值電壓參數(shù)VDRM、VRRM應(yīng)保證在正常使用電壓峰值的2-3倍以上，考慮到一些可能會(huì)出現(xiàn)的浪涌電壓因素，在選擇代用參數(shù)的時(shí)候,只能向高一檔的參數(shù)選取。2.選擇額定工作電流參數(shù)可控硅的額定電流是在一定條件的通態(tài)均勻電流IT，即在環(huán)境溫度為+40℃和規(guī)定冷卻條件，器件在阻性負(fù)載的單相工頻正弦半波，導(dǎo)通角不少于l70℃的電路中，當(dāng)穩(wěn)定的額定結(jié)溫時(shí)所答應(yīng)的通態(tài)均勻電流。而一般變流器工作時(shí)，各臂的可控硅有不均流因素?？煽毓柙诙鄶?shù)的情況也不可能在170℃導(dǎo)通角上工作，通常是少于這一角度。這樣就必須選用可控硅的額定電流稍大一些，一般應(yīng)為其正常電流均勻值的。3.選擇關(guān)斷時(shí)間晶閘管模塊在陽極電流減少為0以后，假如馬上就加上正朝陽極電壓，即使無門極信號，它也會(huì)再次導(dǎo)通。淄博晶閘管驅(qū)動(dòng)模塊哪家好淄博正高電氣注重于產(chǎn)品的環(huán)保性能，將應(yīng)用美學(xué)與環(huán)保健康結(jié)合起來。</p><div

晶閘管也是在電器元器件中普遍存在的一種產(chǎn)品。軟啟動(dòng)器中可控硅模塊是比較重要的一環(huán)，所以保護(hù)好可控硅模塊能夠的延長軟啟動(dòng)器的使用壽命。可控硅模塊與其它功率器件一樣，工作時(shí)由于自身功耗而發(fā)熱。如果不采取適當(dāng)措施將這種熱量散發(fā)出去，就會(huì)引起模塊管芯PN結(jié)溫度急劇上升。致使器件特性惡化，直至完全損壞。晶閘管的功耗主要由導(dǎo)通損耗、開關(guān)損耗、門極損耗三部分組成。在工頻或400Hz以下頻率的應(yīng)用中主要的是導(dǎo)通損耗。散熱器的常用散熱方式有：自然風(fēng)冷、強(qiáng)迫風(fēng)冷、熱管冷卻、水冷、油冷等。正常工作情況的軟啟動(dòng)器設(shè)備有，主要以熱量的形式散失在環(huán)境當(dāng)中，所以我們要先解決軟啟動(dòng)器工作環(huán)境的溫度問題，若工作環(huán)境的溫度過高則將危害到軟啟動(dòng)器的工作，導(dǎo)致軟啟動(dòng)器過熱保護(hù)跳閘。保證軟起動(dòng)器具有良好的運(yùn)行環(huán)境，須對變頻器及運(yùn)行環(huán)境的溫度控制采取相應(yīng)的措施。給軟啟動(dòng)器預(yù)留一定的空間，定期給軟啟動(dòng)器進(jìn)行清灰處理，都是能夠有效降低可控硅溫度的方式。以上就是正高可控硅模塊廠家為您介紹的軟啟動(dòng)器可控硅降溫的重要性，希望對您有所幫助。晶閘管模塊的專業(yè)術(shù)語，您知道幾個(gè)？相信大家對于晶閘管模塊并不陌生了。</p><p>

中頻電源啟動(dòng)用晶閘管擊穿故障的維修方法正高客戶反映，車間內(nèi)感應(yīng)容量用晶閘管發(fā)生擊穿故障，影響到設(shè)備的正常使用。通過對客戶電路圖的分析，以及設(shè)備故障的排查發(fā)現(xiàn)故障原因如下：當(dāng)設(shè)備按下啟動(dòng)按鈕之后，中頻電源逆變成功。但是，如果交流器線圈不失電，電路與諧振曹路間的觸點(diǎn)閉合的情況下，設(shè)備內(nèi)部電路回路相同。此時(shí)，如果回路直流電壓升高，則容易發(fā)生設(shè)備擊穿問題。此類故障主要發(fā)生于運(yùn)行時(shí)間比較長的設(shè)備，由于設(shè)備年限較長，設(shè)備內(nèi)部電路的元件容易出現(xiàn)老化的現(xiàn)象。在設(shè)備電路接通時(shí)，啟動(dòng)電容電容量較小，電壓的急劇升高，就造成電壓疊加和迅速升高，繼而導(dǎo)致晶閘管擊穿問題的發(fā)生。中頻電源啟動(dòng)用晶閘管擊穿問題的排除，可以增加電路中電容器電容量，并對擊穿晶閘管進(jìn)行更換，即可解除這一故障。談?wù)呔чl管的強(qiáng)觸發(fā)問題正高晶閘管以其良好的通斷性能，廣泛應(yīng)用于各類儀器設(shè)備當(dāng)中。作為一種電流控制型的雙極型半導(dǎo)體器件，晶閘管能夠向門極提供一個(gè)特別陡直的尖峰電流脈沖，以保證在任何時(shí)刻均能可靠觸發(fā)晶閘管。晶閘管的門極觸發(fā)脈沖特性對晶閘管的額定值和特性參數(shù)有非常強(qiáng)烈的影響。淄博正高電氣熱誠歡迎各界朋友前來參觀、考察、洽談業(yè)務(wù)。淄博晶閘管模塊</p><p
