過電壓會(huì)對(duì)可控硅模塊造成損壞，如果要想保護(hù)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(huì)對(duì)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(duì)過電壓非常敏感，當(dāng)正向電壓超過udrm值時(shí)，可控硅會(huì)誤導(dǎo)并導(dǎo)致電路故障；當(dāng)施加的反向電壓超過urrm值時(shí)，可控硅模塊會(huì)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(chǔ)能的急劇變化，使系統(tǒng)轉(zhuǎn)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(guān)開啟和關(guān)閉引起的沖擊電壓。雷擊或高壓斷路器動(dòng)作產(chǎn)生的過電壓是幾微秒到幾毫秒的電壓尖峰，對(duì)可控硅模塊非常危險(xiǎn)。 </p> <p> <br /> </p> <span style="display:none;"></span><p> 您知道可控硅模塊的導(dǎo)通條件是什么嗎？ </p> <p> 可控硅模塊導(dǎo)通的條件是陽極承受正電壓，只有當(dāng)正向觸發(fā)電壓時(shí)，可控硅才能導(dǎo)通。由門級(jí)施加的正向觸發(fā)脈沖的較小寬度應(yīng)使陽極電流達(dá)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?dǎo)通后的電壓降很小。 </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(fù)載電路中的電阻。 </p> <p> 以上是可控硅模塊的導(dǎo)通狀態(tài)，希望能幫助您淄博正高電氣有限公司以質(zhì)量求生存，以信譽(yù)求發(fā)展！</p><div

雙向可控硅是一個(gè)三端元件，但我們不再稱其兩極為陰陽極，而是稱作T1和T2極，G為控制極，其控制極上所加電壓無論為正向觸發(fā)脈沖或負(fù)向觸發(fā)脈沖均可使控制極導(dǎo)通，但是觸發(fā)靈敏度互不相同，即保證雙向可控硅能進(jìn)入導(dǎo)通狀態(tài)的較小門極電流IGT是有區(qū)別的。 </p> <p> 2.可控硅過載的保護(hù) </p> <p> 可控硅元件優(yōu)點(diǎn)很多，但是它過載能力差，短時(shí)間的過流，過壓都會(huì)造成元件損壞，因此為保證元件正常工作，需有條件： </p> <p> （1）外加電壓下允許超過正向轉(zhuǎn)折電壓，否則控制極將不起作用； </p> <p> （2）可控硅的通態(tài)平均電流從安全角度考慮一般按較大電流的1.5~2倍來?。?</p> <p> （3）為保證控制極可靠觸發(fā)，加到控制極的觸發(fā)電流一般取大于其額值，除此以外，還必須采取保護(hù)措施，一般對(duì)過流的保護(hù)措施是在電路中串入快速熔斷器，其額定電流取可控硅電流平均值的1.5倍左右，其接入的位置可在交流側(cè)或直流側(cè)，當(dāng)在交流側(cè)時(shí)額定電流取大些，一般多采用前者，過電壓保護(hù)常發(fā)生在存在電感的電路上，或交流側(cè)出現(xiàn)干擾的浪涌電壓或交流側(cè)的暫態(tài)過程產(chǎn)生的過壓。由于，過電壓的尖峰高，作用時(shí)間短，常采用電阻和電容吸收電路加以。
