紅表筆接K極時，電阻呈低阻值，對其它情況電阻值均為無窮大。由此可迅速判定G、K極，剩下的就是A極。2．檢查觸發(fā)能力如圖2(a)所示，首先將表Ⅰ的黑表筆接A極，紅表筆接K極，電阻為無窮大；然后用黑表筆尖也同時接觸G極，加上正向觸發(fā)信號，表針向右偏轉(zhuǎn)到低阻值即表明GTO已經(jīng)導(dǎo)通；脫開G極，只要GTO維持通態(tài)，就說明被測管具有觸發(fā)能力，鋼鐵廠可控硅集成調(diào)壓模塊供應(yīng)商。3．檢查關(guān)斷能力現(xiàn)采用雙表法檢查GTO的關(guān)斷能力，如圖2(b)所示，表Ⅰ的檔位及接法保持不變。將表Ⅱ撥于R×10檔，紅表筆接G極，黑表筆接K極，施以負(fù)向觸發(fā)信號，如果表Ⅰ的指針向左擺到無窮大位置，證明GTO具有關(guān)斷能力。4．估測關(guān)斷增益βoff進(jìn)行到第3步時，先不接入表Ⅱ，記下在GTO導(dǎo)通時表Ⅰ的正向偏轉(zhuǎn)格數(shù)n1；再接上表Ⅱ強迫GTO關(guān)斷，記下表Ⅱ的正向偏轉(zhuǎn)格數(shù)n2。根據(jù)讀取電流法按下式估算關(guān)斷增益：βoff=IATM/IGM≈IAT/IG=K1n1/K2n2式中K1—表Ⅰ在R×1檔的電流比例系數(shù)；K2—表Ⅱ在R×10檔的電流比例系數(shù)。βoff≈10×n1/n2此式的優(yōu)點是。不需要具體計算IAT、IG之值，只要讀出二者所對應(yīng)的表針正向偏轉(zhuǎn)格數(shù)，即可迅速估測關(guān)斷增益值。晶體閘流管注意事項編輯（1）在檢查大功率GTO器件時，鋼鐵廠可控硅集成調(diào)壓模塊供應(yīng)商，建議在R×1檔外邊串聯(lián)一節(jié)′，鋼鐵廠可控硅集成調(diào)壓模塊供應(yīng)商。正高電氣以顧客為本，誠信服務(wù)為經(jīng)營理念。鋼鐵廠可控硅集成調(diào)壓模塊供應(yīng)商</p><div

1、過流保護(hù)如果想得到較安全的過流保護(hù)，建議用戶優(yōu)先使用內(nèi)部帶過流保護(hù)作用的模塊。另外還可采用外接快速熔斷器、快速過電流繼電器、傳感器的方法?？焖偃蹟嗥魇?*簡單常用的方法，介紹如下：（1）快速熔斷器的選擇：①、熔斷器的額定電壓應(yīng)大于模塊輸入端電壓；②、熔斷器的額定電流應(yīng)為模塊標(biāo)稱輸入電流的，按照計算值選擇相同電流或稍大一點的熔斷器。模塊輸入、輸出電流的換算關(guān)系參考本本博客有關(guān)文章。用戶也可根據(jù)經(jīng)驗和試驗自行確定熔斷器的額定電流。（2）接線方法：快速熔斷器接在模塊的輸入端，負(fù)載接輸出端。2、過壓保護(hù)晶閘管承受過電壓的能力較差，當(dāng)元件承受的反向電壓超過其反向擊穿電壓時，即使時間很短，也會造成元件反向擊穿損壞。如果正向電壓超過晶閘管的正向轉(zhuǎn)折電壓，會引起晶閘管硬開通，它不僅使電路工作失常，且多次硬開通后元件正向轉(zhuǎn)折電壓要降低，甚至失去正向阻斷能力而損壞。因此必須采用過電壓保護(hù)措施用以晶閘管上可能出現(xiàn)的過電壓。模塊的過壓保護(hù)，推薦采用阻容吸收和壓敏電阻兩種方式并用的保護(hù)措施。（1）阻容吸收回路晶閘管從導(dǎo)通到阻斷時，和開關(guān)電路一樣，因線路電感（主要是變壓器漏感LB）釋放能量會產(chǎn)生過電壓。正高電氣永遠(yuǎn)是您身邊的行業(yè)**！</p><div
