在實(shí)際應(yīng)用中，除合理選擇智能可控硅調(diào)壓模塊的額定電壓及電流外，還必須采取有效的保護(hù)措施來保證晶閘管智能模塊能可靠工作。 </p> <p> 過熱保護(hù)：晶閘管智能模塊與其他功率器件一樣，在實(shí)際工作中由于自身功耗，都會(huì)引起芯片溫度上升，溫度過高后，會(huì)使漏電流增加，芯片特性變軟，直至過熱擊穿，在實(shí)際應(yīng)用中，通常采用強(qiáng)迫風(fēng)冷的方法來及時(shí)散除晶閘管工作時(shí)產(chǎn)生的熱量，控制散熱器比較高溫度不超過75°，使晶閘管智能模塊在安全溫度下工作。聊城晶閘管智能模塊正高電氣具備雄厚的實(shí)力和豐富的實(shí)踐經(jīng)驗(yàn)。</p><div

在緩慢放大面板上“給定”電位器的操作中，應(yīng)密切注意電流表的反應(yīng)，若電流表的指示迅速增大，則應(yīng)迅速把“給定”電位器逆時(shí)針旋下來，此時(shí)表明電流取樣電路有問題，系統(tǒng)處于電流開環(huán)狀態(tài)，應(yīng)檢查電流互感器是否接對(duì)，特別是5A：、付邊是否接反，Ω電阻是否接上，正常的表現(xiàn)是隨著“給定”電位器的緩慢加大，電流表的指示也跟著增大，當(dāng)停止旋轉(zhuǎn)“給定”電位器時(shí)，電流表的指示能穩(wěn)定的停在某一刻度上。當(dāng)出現(xiàn)直通現(xiàn)象時(shí)，把面板上的“給定”電位器順時(shí)針旋大，使電流表的指示接近額定值的50%左右。用交流電壓表測(cè)量CON2-3、CON2-4、CON2-5三個(gè)接線端子間的電壓，三個(gè)電壓應(yīng)該是大致相等的，若相差太大，說明電流互感器的同名端接錯(cuò)，必須改對(duì)，否則會(huì)影響電流調(diào)節(jié)器的正常工作。繼續(xù)把面板上的“給定”電位器順時(shí)針旋到頭，電流表的指示應(yīng)接近額定值，逆時(shí)針調(diào)節(jié)主控制板上的W1電流反饋微調(diào)電位器，使直流電流表指示到額定輸出電流，完成了額定電流的整定。這樣整流橋的測(cè)試就基本完成，可以進(jìn)行逆變橋的調(diào)試。需要指出的是，當(dāng)平波電抗器的直流電阻較小時(shí)，在直通狀態(tài)下作額定電流的整定，會(huì)出現(xiàn)直流電流振蕩的現(xiàn)象，可在直流回路里串一點(diǎn)電阻加以解決。另外。</p><p> 通過W1微調(diào)電位器可整定過流電平。當(dāng)三相交流輸入缺相時(shí)，本控制板均能對(duì)電源實(shí)現(xiàn)保護(hù)和指示。其原理是：由4#、6#、2#晶閘管的陰極（K）分別取A、B、C三相電壓信號(hào)（通過門極引線），經(jīng)過光電耦合器的隔離送到IC6進(jìn)行檢測(cè)和判別，一旦出現(xiàn)“缺相”故障時(shí)，除了整流觸發(fā)脈沖外，還驅(qū)動(dòng)“”LED指示燈以及報(bào)警繼電器。為了使控制電路能夠更可靠準(zhǔn)確的運(yùn)行，控制電路上還設(shè)置了啟動(dòng)定時(shí)器和控制電源欠壓檢測(cè)保護(hù)。在開機(jī)的瞬間，控制電路的工作是不穩(wěn)定的，設(shè)置一個(gè)3秒鐘左右的定時(shí)器，待定時(shí)過后，才容許輸出觸發(fā)脈沖。這部分電路由IC2B等元件構(gòu)成。若由于某種原因造成控制板上直流供電電壓過低，穩(wěn)壓器不能穩(wěn)壓，亦會(huì)使控制出錯(cuò)。設(shè)置一個(gè)欠壓檢測(cè)電路（由IC2A等組成），當(dāng)電壓低于整流觸發(fā)脈沖，防止不正確的觸發(fā)，同時(shí)點(diǎn)亮“”LED批示燈和驅(qū)動(dòng)報(bào)警繼電器。自動(dòng)重復(fù)起動(dòng)電路在IC8內(nèi)部。微動(dòng)開關(guān)DIP-1用于關(guān)閉自動(dòng)重復(fù)起動(dòng)電路。Q2組成中頻過電壓檢測(cè)，輸入到IC6的29P，整流觸發(fā)脈沖；驅(qū)動(dòng)“”LED指示燈亮和驅(qū)動(dòng)報(bào)警繼電器；同時(shí)使過壓保護(hù)振蕩器起振。過電壓保護(hù)動(dòng)作后，也像過流保護(hù)一樣，只有通過復(fù)位信號(hào)或通過關(guān)機(jī)后再開機(jī)進(jìn)行“上電復(fù)位”，方可再次運(yùn)行。我公司將以優(yōu)良的產(chǎn)品，周到的服務(wù)與尊敬的用戶攜手并進(jìn)！</p><div

但是在設(shè)定電流限值時(shí)必須要根據(jù)電動(dòng)機(jī)的初始轉(zhuǎn)矩來設(shè)定，否則設(shè)置過小會(huì)起動(dòng)失敗或燒壞電機(jī)。此種起動(dòng)方式起動(dòng)時(shí)間相對(duì)較長(zhǎng)。圖3限流起動(dòng)4、突跳起動(dòng)這種起動(dòng)方式主要應(yīng)用在負(fù)載相對(duì)較重的工作環(huán)境下。在轉(zhuǎn)矩控制的基礎(chǔ)下，在起動(dòng)的瞬間采用一個(gè)突跳轉(zhuǎn)矩用來克服負(fù)載的靜轉(zhuǎn)矩，然后轉(zhuǎn)矩在逐漸上升，直至電動(dòng)機(jī)到達(dá)正常工作狀態(tài)。這種起動(dòng)方式的優(yōu)點(diǎn)是可以縮短起動(dòng)時(shí)間，起動(dòng)較重的負(fù)載，但在起動(dòng)的時(shí)候會(huì)對(duì)電網(wǎng)產(chǎn)生一定的沖擊，影響同一電網(wǎng)下其他負(fù)荷的工作。圖4突跳起動(dòng)5、軟停車軟停車的實(shí)際上就相當(dāng)于相反軟起動(dòng)過程，主要作用是消除了系統(tǒng)的反慣性沖擊，對(duì)于泵類負(fù)載來講就是克服了“水錘”效應(yīng)。其主要過程是在電動(dòng)機(jī)實(shí)行軟停車時(shí)軟起動(dòng)裝置的旁路接觸器斷開，同時(shí)晶閘管開始工作，使電機(jī)電壓逐漸下降，轉(zhuǎn)速降低，達(dá)到軟停車的效果。（如圖5）圖5軟起動(dòng)和軟停車全過程6、泵控起動(dòng)及停車由于水泵類負(fù)載其相對(duì)特殊的機(jī)械特性，部分軟起動(dòng)廠家針對(duì)泵類負(fù)載的特性曲線專門設(shè)計(jì)了泵控型起動(dòng)和停車方式，該種起動(dòng)方式可以通過電機(jī)平滑的加速和減速，使離心泵在起動(dòng)和停機(jī)期間降低水錘沖擊。主控電路通過采集信號(hào)分析電機(jī)的各個(gè)運(yùn)行參數(shù)。聊城晶閘管智能模塊</p><p
