src="https://tyunfile.71360.com/UploadFile/szmdjd/637393089690316908/4897128.png"></div><p> （一）電源：用萬用表測一下主電路開關(guān)（接觸器）和控制保險絲后面是否有電，這將排除這些元件斷路的可能性。 </p> <p> （二）整流器：整流器采用三相全控橋式整流電路，它包括六個快速熔斷器、六個晶閘管、六個脈沖變壓器和一個續(xù)流二極管。在快速熔斷器上有一個紅色的指示器，正常時指示器縮在外殼里邊，當(dāng)快熔燒斷后它將彈出，有些快熔的指示器較緊，當(dāng)快熔燒斷后，它會卡在里面，所以為可靠起見，可以用萬用表通斷檔測一下快熔，以判斷它是否燒斷。 </p> <p> 測量晶閘管的簡單方法是用萬用表電阻擋（200Ω擋）測一下其陰極—陽極、門極—陰極電阻，測量時晶閘管不用取下來。正常情況下，陽極—陰極間電阻應(yīng)為無窮大，門極—陰極電阻應(yīng)在10—50Ω之間，過大或過小都表明這只晶閘管門極失效，它將不能被觸發(fā)導(dǎo)通。 </p> <p> 脈沖變壓器次邊接在晶閘管上，原邊接在主控板上，用萬用表測量原邊電阻約為50Ω。續(xù)流二極管一般不容易出現(xiàn)故障，檢查時用萬用表二極管擋測其二端，正向時萬用表顯示結(jié)壓降約有500mV，反向不通。 </p> <p> （三）逆變器：逆變器包括四只快速晶閘管和四只脈沖變壓器，可以按上述方法檢查。 </p> <p> <br />

style="text-indent:25px">水冷電纜：水冷電纜的作用是連接中頻電源和感應(yīng)線圈，它是用每根直徑Φ0.6–Ф0.8紫銅線絞合而成。對于500公斤電爐，電纜截面積為480平方毫米，對于250公斤電爐，電纜截面積采用300至400平方毫米。水冷電纜外膠管采用耐壓5公斤的壓力橡膠管，里面通以冷卻水，它是負(fù)載回路的一部分，工作時受到拉力和扭力，與爐體一起傾動而發(fā)生曲折，因此時間長后容易在柔性連接處斷裂開。水冷電纜斷裂過程，一般是先斷掉大部分后，在大功率運行時把未斷小部分很快燒斷，這時中頻電源就會產(chǎn)生很高的過電壓，如果過電壓保護不可靠，就會燒壞晶閘管。水冷電纜斷開后，中頻電源無法啟動工作。如不檢查出原因而反復(fù)啟動，就很可能燒壞中頻電壓互感器。檢查故障時可用示波器，把示波器探頭夾在負(fù)載兩端，觀察按啟動按鈕時有無衰減波形。確定電纜斷芯時先把水冷電纜與電熱電容器輸出銅排脫開，用萬用表電阻擋（200Ω擋）測量電纜的電阻值，正常時電阻值為零，斷開時為無窮大。用萬用表測量時，應(yīng)把爐體翻到傾倒位置，使水冷電纜掉起，這樣使斷處徹底脫離，才能正確判斷是否斷芯。</p><p> 變壓器：每個變壓器的每個繞組都應(yīng)該是通的，一般原邊阻值約有幾十歐姆，次極幾歐姆。應(yīng)該注意：中頻電壓互感器的原邊與負(fù)載并聯(lián)，所以其電阻值為零。 </p> <p> （五）電容器：與負(fù)載并聯(lián)的電熱電容器可能被擊穿，電容器一般分組安裝在電容器架上，檢查時應(yīng)先確定被擊穿電容器所在的組。斷開每組電容器的匯流母排與主匯流排之間的連接點，測量每組電容器兩個匯流排間的電阻，正常時應(yīng)為無窮大。確認(rèn)壞的組后，再斷開每臺電熱電容器引至匯流排的軟銅皮，逐臺檢查即可找到擊穿的電容器。每臺電熱電容器由四個芯子組成，外殼為一極，另一極分別通過四個絕緣子引到端蓋上，一般只會有一個芯子被擊穿，跳開這個絕緣子上的引線，這臺電容器可以繼續(xù)使用，其容量是原來的3/4。電容器的另一個故障是漏油，一般不影響使用，但要注意防火。 </p> <p> 安裝電容器的角鋼與電容器架是絕緣的，如果絕緣擊穿將使主回路接地，測量電容器外殼引線和電容器架之間的電阻，可以判斷這部分的絕緣狀況。可編程實驗室直流電源。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
