可控硅元件在電氣設(shè)備中發(fā)揮重大作用，但可控硅使用中必須要注意運(yùn)行環(huán)境和相關(guān)指標(biāo)，防止可控硅損壞而影響到設(shè)備的正常使用。對此，在選用可控硅的額定電壓時(shí)，應(yīng)參考實(shí)際工作條件下的峰值電壓的大小，并留出一定的余量。 </p> <p> <p> 1、選用可控硅的額定電流時(shí)，除了考慮通過元件的平均電流外，還應(yīng)注意正常工作時(shí)導(dǎo)通角的大小、散熱通風(fēng)條件等因素。在工作中還應(yīng)注意管殼溫度不超過相應(yīng)電流下的允許值。 </p> <p> 2、使用可控硅之前，應(yīng)該用萬用表檢查可控硅是否良好。發(fā)現(xiàn)有短路或斷路現(xiàn)象時(shí)，應(yīng)立即更換。 </p> <p> 3、嚴(yán)禁用兆歐表(即搖表)檢查元件的絕緣情況。 </p> <p> 4、電流為5A以上的可控硅要裝散熱器，并且保證所規(guī)定的冷卻條件。為保證散熱器與可控硅管心接觸良好，它們之間應(yīng)涂上一薄層有機(jī)硅油或硅脂，以幫于良好的散熱。 </p> <p> 5、按規(guī)定對主電路中的可控硅采用過壓及過流保護(hù)裝置。 </p> <p> 6、要防止可控硅控制極的正向過載和反向擊穿。 </p>

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>
