1.在選擇可控硅模塊的額定電流時，應注意的是，除考慮通過元件的平均電流外，還必須注意正常運行過程中傳導角的大小、散熱和通風條件等因素，同時，管殼的溫度不得超過相應電流的允許值。 </p> <p> 2.使用可控硅模塊時，使用萬用表檢查可控硅模塊是否處于良好狀態(tài)，如有短路或斷路，應立即更換。 </p> <p> 3.嚴禁使用兆歐表來檢查部件的絕緣情況。 </p> <p> 4.率大于5A的可控硅模塊，應安裝散熱器，并保證規(guī)定的冷卻條件。同時，為保證散熱器與可控硅模塊管芯接觸良好，應在兩者之間涂一層有機硅油或硅脂，以利于更好的散熱。 </p> <p> 5.根據(jù)規(guī)定，主電路中的可控硅模塊采用過電壓和過電流保護裝置。 </p> <p> 6.防止控制極正向過載和反向擊穿。東營高壓可控硅模塊組件淄博正高電氣有限公司銳意進取，持續(xù)創(chuàng)新為各行各業(yè)提供專業(yè)化服務。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

可控硅模塊導通的條件是陽極承受正電壓，只有當正向觸發(fā)電壓時，可控硅才能導通。由門級施加的正向觸發(fā)脈沖的較小寬度應使陽極電流達到維持直通狀態(tài)所需的較小的陽極電流，即高于電流IL?？煽毓鑼ê蟮碾妷航岛苄?。 </p> <p> 接通可控硅模塊的條件是將流過可控硅模塊的電流減小到較小的值，即保持電流IH。有兩種方法： </p> <p> 1.將正極電壓降低至數(shù)值，或添加反向陽極電壓。 </p> <p> 2.增加負載電路中的電阻。 </p> <p> 以上是可控硅模塊的導通狀態(tài)，希望能幫助您 </p><p> 滿足可控硅模塊工作的必要條件： </p> <p> （1）+12V直流電源：可控硅模塊內部控制電路的工作電源。 </p> <p> ①可控硅模塊輸出電壓要求：+12V電源：12±0.5V ，紋波電壓小于20mv 。 </p> <p> ②可控硅模塊輸出電流要求：標稱電流小于500安培產品：I+12V＞0.5A，標稱電流大于500安培產品：I+12V＞ 1A。 </p> <p> （2）可控硅模塊控制信號：0～10V或4～20mA控制信號，用于對輸出電壓大小進行調整的控制信號，正極接CON10V或CON20mA，負極接GND1。 </p> <p> （3）可控硅模塊供電電源和負載：供電電源一般為電網(wǎng)電源，電壓460V以下的或者供電變壓器，接可控硅模塊的輸入端子；負載為用電器，接可控硅模塊的輸出端子。淄博正高電氣有限公司堅持“顧客至上，合作共贏”。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">可控硅元件控制大電感負載時會有干擾電網(wǎng)和自干擾的現(xiàn)象，其原因是當可控硅元件控制一個連接電感性負載的電路斷開或閉合時，其線圈中的電流通路被切斷，其變化率極大，因此在電感上產生一個高電壓，這個電壓通過電源的內阻加在開關觸點的兩端，然后感應電壓一次次放電直到感應電壓低于放電所必須的電壓為止，在這一過程中將產生極大的脈沖束。這些脈沖束疊加在供電電壓上，并且把干擾傳給供電線或以輻射形式傳向周圍空間，這種脈沖具有很高的幅度，很寬的頻率，因而具有感性負載的開關點是一個很強的噪聲源。我們愿與您共同努力，共擔風雨，合作共贏。東營高壓可控硅模塊組件</p><p

在性能上，可控硅不僅具有單向導電性，而且還具有比硅整流元件(俗稱“死硅”)更為可貴的可控性。它只有導通和關斷兩種狀態(tài)。 </p> <p> 可控硅能以毫安級電流控制大功率的機電設備，如果超過此頻率，因元件開關損耗明顯增加，允許通過的平均電流相降低，此時，標稱電流應降級使用。 </p> <p> 可控硅的優(yōu)點很多，例如：以小功率控制大功率，功率放大倍數(shù)高達幾十萬倍;反應極快，在微秒級內開通、關斷;無觸點運行，無火花、無噪音;效率高，成本低等等。 </p> <p> 可控硅的弱點：靜態(tài)及動態(tài)的過載能力較差;容易受干擾而誤導通。 </p> <p> 可控硅從外形上分類主要有：螺栓形、平板形和平底形。東營高壓可控硅模塊組件</p><p
