 學習下耐電弧試驗機的操作步驟

操作步驟:

1. 拉開有機(ji)玻璃門(men),放置(zhi)好(hao)(hao)電(dian)極(ji)與(yu)試樣(yang),用測量塊測量好(hao)(hao)兩個電(dian)極(ji)之(zhi)間的距離并固定住兩個電(dian)極(ji);連(lian)接上(shang)高(gao)壓端(duan)(duan)的高(gao)壓線(xian)(xian)與(yu)低(di)壓端(duan)(duan)的地線(xian)(xian),連(lian)接好(hao)(hao)試驗(yan)主機(ji)與(yu)實驗(yan)室(shi)的接地線(xian)(xian),關(guan)(guan)上(shang)有機(ji)玻璃門(men)(注意:如果(guo)門(men)沒有關(guan)(guan)好(hao)(hao),按下(xia)試驗(yan)按鈕(niu)不會響(xiang)應(ying));

2. 打開(kai)試(shi)驗(yan)(yan)主(zhu)機電(dian)源并預熱(re)10—15分鐘(注意:試(shi)驗(yan)(yan)主(zhu)機與(yu)電(dian)腦(nao)(nao)的電(dian)源不能公用一(yi)個電(dian)源),初始狀(zhuang)態為(wei)停止按(an)(an)鈕上(shang)的紅色指示(shi)(shi)燈(deng)亮,試(shi)驗(yan)(yan)按(an)(an)鈕上(shang)的綠(lv)色指示(shi)(shi)燈(deng)滅;打開(kai)電(dian)腦(nao)(nao),準備試(shi)驗(yan)(yan);

3. 打開耐(nai)電弧實驗(yan)軟件,設置試驗(yan)參數;

4. 按(an)(an)下“試(shi)驗(yan)按(an)(an)鈕(niu)(niu)"(綠(lv)(lv)色(se)指示(shi)(shi)(shi)燈(deng)(deng)亮(liang),紅色(se)指示(shi)(shi)(shi)燈(deng)(deng)滅),點(dian)擊(ji)“10mA 1/8通(tong)(tong)7/8段(duan)(duan)(duan)(duan)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)1),當(dang)60s后(hou)自(zi)動停(ting)(ting)止高壓(ya)(注(zhu)意:綠(lv)(lv)色(se)指示(shi)(shi)(shi)燈(deng)(deng)是亮(liang)的,試(shi)驗(yan)時間(jian)不(bu)可更改不(bu)要拉開有(you)機玻(bo)璃門),再點(dian)擊(ji)“10mA 1/4通(tong)(tong)3/4段(duan)(duan)(duan)(duan)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)2),當(dang)60s后(hou)自(zi)動停(ting)(ting)止高壓(ya),再點(dian)擊(ji)“10mA 1/4通(tong)(tong)1/4段(duan)(duan)(duan)(duan)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)3),當(dang)60s后(hou)自(zi)動停(ting)(ting)止高壓(ya),再點(dian)擊(ji)“10mA 連(lian)續(xu)(xu)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)4),當(dang)60s后(hou)自(zi)動停(ting)(ting)止高壓(ya);再點(dian)擊(ji)“20mA 連(lian)續(xu)(xu)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)5),每(mei)個(ge)實驗(yan)階(jie)(jie)段(duan)(duan)(duan)(duan)的試(shi)驗(yan)時間(jian)為(wei)60s,60s后(hou)如果(guo)試(shi)樣沒有(you)擊(ji)穿,接在點(dian)擊(ji)“30 mA 連(lian)續(xu)(xu)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)6)如果(guo)60s后(hou)沒有(you)擊(ji)穿,再點(dian)擊(ji)“40 mA 連(lian)續(xu)(xu)"(即(ji)階(jie)(jie)段(duan)(duan)(duan)(duan)7)60s后(hou)停(ting)(ting)止,按(an)(an)下“停(ting)(ting)止按(an)(an)鈕(niu)(niu)"(綠(lv)(lv)色(se)指示(shi)(shi)(shi)燈(deng)(deng)滅,紅色(se)指示(shi)(shi)(shi)燈(deng)(deng)亮(liang));

   如果試(shi)樣(yang)在某個階段被(bei)擊穿,這時實驗人員需要點擊“結束試(shi)驗",并按下“停止按鈕"(綠色指(zhi)(zhi)示燈滅,紅色指(zhi)(zhi)示燈亮)來停止試(shi)驗,拉開有機玻璃門更換試(shi)樣(yang),重復(fu)上述步驟試(shi)驗;

4. 嚴(yan)禁熱插撥串口(kou)通訊線(正(zheng)確(que)操作為,關掉試驗主(zhu)機(ji)電源再拔下通     ;    訊線);

5. 如果(guo)試(shi)驗(yan)(yan)中有事需要(yao)離(li)開(kai),請點擊“結束試(shi)驗(yan)(yan)"并(bing)按下紅色“停止按鈕",關掉(diao)試(shi)驗(yan)(yan)主機(ji)電源后再離(li)開(kai);
