在選用晶閘管模塊的額定電流時(shí)，就要注意，除了要考慮通過元件的平均電流之外，還要注意正常工作時(shí)導(dǎo)通角的大小、散熱通風(fēng)條件等諸多因素，淄博晶閘管驅(qū)動(dòng)模塊生產(chǎn)廠家，與此同時(shí)，管殼溫度不得超過相應(yīng)電流下的允許值。使用晶閘管模塊，要用萬(wàn)用表檢查晶閘管模塊是否良好，發(fā)現(xiàn)有短路或者斷路現(xiàn)象時(shí)，就要立即更換。嚴(yán)禁使用兆歐表來(lái)檢查元件的絕緣情況。電力為5A以上的晶閘管模塊要裝散熱器，并且保證所規(guī)定的冷卻條件，同時(shí)，為了保證散熱器與晶閘管模塊的管心接觸良好，它們之間也要涂上一層有機(jī)硅油或者是硅脂，以幫助能夠更加良好的散熱。按照規(guī)定來(lái)對(duì)主電路中的晶閘管模塊采用過壓及過流保護(hù)裝置。防止控制極的正向過載和反向擊穿。使用晶閘管模塊以上常識(shí)一定要了解，淄博晶閘管驅(qū)動(dòng)模塊生產(chǎn)廠家，只有這樣才能保證晶閘管模塊更安全的運(yùn)行。傳統(tǒng)的電加熱行業(yè)使用的功率器件一般采用分離的單只晶閘管和晶閘管觸發(fā)板的方式來(lái)完成對(duì)變壓器初級(jí)或次級(jí)的調(diào)壓;加熱行業(yè)往往工作環(huán)境很惡劣，淄博晶閘管驅(qū)動(dòng)模塊生產(chǎn)廠家，粉塵飛揚(yáng)，溫度變化較大，濕度較高，長(zhǎng)時(shí)間工作后會(huì)出現(xiàn)觸發(fā)板工作失常，造成晶閘管擊穿，導(dǎo)致設(shè)備停產(chǎn)，產(chǎn)品報(bào)廢等，給生產(chǎn)造成眼中損失。并且普通電工無(wú)法完成維修工作，必須專業(yè)人員進(jìn)行操作。為了避免出現(xiàn)上述問題。淄博正高電氣得到市場(chǎng)的一致認(rèn)可。淄博晶閘管驅(qū)動(dòng)模塊生產(chǎn)廠家</p><div

發(fā)出個(gè)觸發(fā)脈沖的時(shí)刻都相同，也就是控制角和導(dǎo)通角都相等，那么，單結(jié)晶體管張弛振蕩器怎樣才能與交流電源準(zhǔn)確地配合以實(shí)現(xiàn)有效的控制呢?為了實(shí)現(xiàn)整流電路輸出電壓“可控”，必須使晶閘管模塊承受正向電壓的每半個(gè)周期內(nèi)，觸發(fā)電路發(fā)出個(gè)觸發(fā)脈沖的時(shí)刻都相同，這種相互配合的工作方式，稱為觸發(fā)脈沖與電源同步。十、怎樣才能做到同步呢?大家再看調(diào)壓器的電路圖(圖1)。請(qǐng)注意，在這里單結(jié)晶體管張弛振蕩器的電源是取自橋式整流電路輸出的全波脈沖直流電壓。在晶閘管模塊沒有導(dǎo)通時(shí)，張弛振蕩器的電容器C被電源充電，UC按指數(shù)規(guī)律上升到峰點(diǎn)電壓UP時(shí)，單結(jié)晶體管VT導(dǎo)通，在VS導(dǎo)通期間，負(fù)載RL上有交流電壓和電流，與此同時(shí)，導(dǎo)通的VS兩端電壓降很小，迫使張弛振蕩器停止工作。當(dāng)交流電壓過零瞬間，晶閘管VS被迫關(guān)斷，張弛振蕩器得電，又開始給電容器C充電，重復(fù)以上過程。這樣，每次交流電壓過零后，張弛振蕩器發(fā)出個(gè)觸發(fā)脈沖的時(shí)刻都相同，這個(gè)時(shí)刻取決于RP的阻值和C的電容量。調(diào)節(jié)RP的阻值，就可以改變電容器C的充電時(shí)間，也就改變了個(gè)Ug發(fā)出的時(shí)刻，相應(yīng)地改變了晶閘管的控制角，使負(fù)載RL上輸出電壓的平均值發(fā)生變化，達(dá)到調(diào)壓的目的。雙向晶閘管模塊的T1和T2不能互換。</p><p>
