可控整流：如同二極管整流一樣，將交流整流為直流，并且在交流電壓不變的情況下，有效地控制直流輸出電壓的大小即可控整流，實現(xiàn)交流→可變直流之轉變; </p> <p> 無觸點功率靜態(tài)開關(固態(tài)開關)：作為功率開關元件，可控硅可以代替接觸器、繼電器用于開關頻率很高的場合。 </p> <p> 因此可控硅元件被廣泛應用于各種電子設備和電子產(chǎn)品的電路中，多作可控整流、逆變、變頻、調(diào)壓、無觸點開關等用途。家用電器中的調(diào)光燈、調(diào)速風扇、冷暖空調(diào)器、熱水器、電視、冰箱、洗衣機、照相機、音響組合、聲控電路、定時控制器、感應燈、圣誕燈控制器、自動門電路、以及玩具裝置、電動工具產(chǎn)品、無線電遙控電路、攝像機等工業(yè)控制領域等都大量使用了可控硅器件。濟南雙向可控硅模塊價格淄博正高電氣有限公司品牌價值不斷提升。</p><div

1 可控硅模塊環(huán)境溫度的測定：在距被測可控硅模塊表面1.5m處放置溫度計，溫度計測點距地面的高度與減速機軸心線等高，溫度計的放置應不受外來輻射熱與氣流的影響，環(huán)境溫度數(shù)值的讀取與工作溫度數(shù)值的讀取應同時進行。 </p> <p> <p> 2 可控硅模塊溫升按下式計算：式中：Δt--可控硅模塊的溫升(℃)。 </p> <p> 3 可控硅模塊工作溫度的測定：被測可控硅模塊溫升的測定，通常與減速機的承載能力及傳動效率測定同時進行，也可單獨進行，被測減速機在符合規(guī)定時，讀取它在額定轉速、額定輸入功率下的工作溫度 </p> </p><p> 過電壓會對可控硅模塊造成損壞，如果要想保護可控硅不受其損壞，就要了解過電壓的產(chǎn)生原因，從而去避免防止受損，下面正高電氣就來講講過電壓會對可控硅模塊造成怎樣的損壞？以及過電壓產(chǎn)生的原因。 </p> <p> 可控硅模塊對過電壓非常敏感，當正向電壓超過udrm值時，可控硅會誤導并導致電路故障；當施加的反向電壓超過urrm值時，可控硅模塊會立即損壞。因此，需要研究過電壓產(chǎn)生的原因和過電壓的方法。 </p> <p> 過電壓主要是由于供電電源或系統(tǒng)儲能的急劇變化，使系統(tǒng)轉換太晚，或是系統(tǒng)中原本積聚的電磁能量消散太晚。主要研究發(fā)現(xiàn)，由于外界沖擊引起的過電壓主要有兩種類型，如雷擊和開關開啟和關閉引起的沖擊電壓。雷擊或高壓斷路器動作產(chǎn)生的過電壓是幾微秒到幾毫秒的電壓尖峰，對可控硅模塊非常危險。 </p> <p> <br />

</p> <p> (3)選擇電流電壓時要留有適當?shù)挠嗔浚?</p> <p> <br /> </p> <p> <p> 可控硅模塊使用注意事項： </p> <p> (1)線路中須有過壓過流保護措施，串并聯(lián)使用時必須有均流措施。 </p> <p> (2)用萬用表簡單判斷器件是否損壞：門陰極間電阻，應有十幾或幾十Ω，否則門極已短路或開路。陰陽極間電阻，應大于1MΩ，（整流管正向除外），電阻小于1MΩ表明器件極間絕緣性能不良，電阻近零時表明器件已擊穿。發(fā)現(xiàn)有短路或斷路現(xiàn)象時，應立即更換。 </p> <p> (3)嚴禁用兆歐表（即搖表）檢查元件的絕緣情況。 </p> <p> (4)電流為5A以上的可控硅模塊要裝散熱器，并且保證所規(guī)定的冷卻條件。為保證散熱器與可控硅模塊管心接觸良好，它們之間應涂上一薄層有機硅油或硅脂，以幫于良好的散熱。 </p> <p> (5)按規(guī)定對主電路中的可控硅模塊采用過壓及過流保護裝置。 </p> <p> (6)要防止可控硅模塊控制極的正向過載和反向擊穿。 </p>

單向晶閘管模塊具有其獨特的特性：當陽極連接到反向電壓時，或陽極連接到正向電壓時，但控制極不增加電壓，則不會導通，當陽極和控制極同時連接到正向電壓時，將變?yōu)榻油顟B(tài)。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)。若要關閉，只能將陽極電壓降到某個臨界值或反向。 </p> <p> 雙向晶閘管模塊的管腳大多按T1、T2和G的順序從左到右排列（當電極管腳朝著帶有字符的一側向下時）。當改變施加到控制極G的觸發(fā)脈沖的大小或時間時，其接通電流的大小可以改變。菏澤雙向可控硅模塊供應商</p><p
