紅表筆接K極時(shí)，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(shí)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。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(shí)，先不接入表Ⅱ，記下在GTO導(dǎo)通時(shí)表Ⅰ的正向偏轉(zhuǎn)格數(shù)n1；再接上表Ⅱ強(qiáng)迫GTO關(guān)斷，記下表Ⅱ的正向偏轉(zhuǎn)格數(shù)n2，甘肅小功率晶閘管模塊。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(diǎn)是。不需要具體計(jì)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)，甘肅小功率晶閘管模塊，即可迅速估測關(guān)斷增益值。晶體閘流管注意事項(xiàng)編輯（1）在檢查大功率GTO器件時(shí)，建議在R×1檔外邊串聯(lián)一節(jié)′，甘肅小功率晶閘管模塊。正高電氣以發(fā)展求壯大，就一定會(huì)贏得更好的明天。甘肅小功率晶閘管模塊</p><div

額定電壓V1mA的下限是線路工作電壓峰值，考慮到電網(wǎng)電壓的波動(dòng)以及多次承受沖擊電流以后V1mA值可能下降，因此，額定電壓的取值應(yīng)適當(dāng)提高。目前通常采用30[%]的余量計(jì)算。V1mA≥√2?U式中U――壓敏電阻兩端正常工作電壓的有效值。壓敏電阻的數(shù)量：三相整流模塊和三相交流模塊均為三只、單相整流模塊和單相交流模塊均為一只。全部接在交流輸入端。3、過熱保護(hù)晶閘管在電流通過時(shí)，會(huì)產(chǎn)生一定的壓降，而壓降的存在則會(huì)產(chǎn)生一定的功耗，電流越大則功耗越大，產(chǎn)生的熱量也就越大。如果不把這些熱量快速散掉，會(huì)造成燒壞晶閘管芯片的問題。因此要求使用晶閘管模塊時(shí)，一定要安裝散熱器。散熱條件的好壞，是影響模塊能否安全工作的重要因素。良好的散熱條件不但能夠保證模塊可靠工作、防止模塊過熱燒毀，而且能夠提高模塊的電流輸出能力。建議用戶在使用大電流規(guī)格模塊的時(shí)候盡量選擇帶過熱保護(hù)作用的模塊。當(dāng)然，即便模塊帶過熱保護(hù)作用，而散熱器和風(fēng)機(jī)也是不可缺少的。在使用中，當(dāng)散熱條件不符合規(guī)定要求時(shí)，如室溫超過40℃、強(qiáng)迫風(fēng)冷的出口風(fēng)速不足6m/s等，則模塊的額定電流應(yīng)立即降低使用，否則模塊會(huì)由于芯片結(jié)溫超過允許值而損壞。譬如。正高電氣以更積極的態(tài)度，更新、更好的產(chǎn)品，更質(zhì)量的服務(wù)，迎接挑戰(zhàn)。</p><div
