電纜直流耐壓測試儀幾種升壓模式：

1、手動升壓模式

開機后(hou)，進入主菜(cai)單，旋(xuan)動(dong)(dong)(dong)(dong)設(she)置(zhi)控(kong)制桿使光標指向“手(shou)動(dong)(dong)(dong)(dong)升(sheng)壓(ya)(ya)"選項，點(dian)擊控(kong)制桿，進入手(shou)動(dong)(dong)(dong)(dong)模式參(can)(can)數設(she)置(zhi)界面(mian)，根(gen)據具(ju)體的(de)試(shi)(shi)驗(yan)(yan)要求設(she)置(zhi)各項參(can)(can)數后(hou)，即可進入升(sheng)壓(ya)(ya)界面(mian)。先按(an)高壓(ya)(ya)通按(an)鈕，紅燈(deng)亮起后(hou)，再旋(xuan)動(dong)(dong)(dong)(dong)旋(xuan)鈕，當電(dian)(dian)壓(ya)(ya)升(sheng)至試(shi)(shi)驗(yan)(yan)電(dian)(dian)壓(ya)(ya)設(she)定值，計(ji)時(shi)器開始計(ji)時(shi)，計(ji)時(shi)完(wan)畢后(hou)系統將自(zi)(zi)動(dong)(dong)(dong)(dong)降壓(ya)(ya)回零(ling)，然后(hou)彈(dan)出(chu)試(shi)(shi)驗(yan)(yan)記(ji)錄(lu)保存對話框，做(zuo)(zuo)出(chu)選擇(ze)后(hou)，該次試(shi)(shi)驗(yan)(yan)完(wan)畢；如果電(dian)(dian)壓(ya)(ya)未(wei)達到設(she)定的(de)試(shi)(shi)驗(yan)(yan)電(dian)(dian)壓(ya)(ya)值時(shi)，按(an)下0.75UDC-1mA按(an)鈕，則系統會(hui)自(zi)(zi)動(dong)(dong)(dong)(dong)降壓(ya)(ya)到當前電(dian)(dian)壓(ya)(ya)值的(de)0.75倍，然后(hou)以(yi)設(she)定的(de)加(jia)壓(ya)(ya)時(shi)間倒(dao)計(ji)時(shi)，計(ji)時(shi)完(wan)畢后(hou)，系統自(zi)(zi)動(dong)(dong)(dong)(dong)降壓(ya)(ya)回零(ling)，然后(hou)彈(dan)出(chu)試(shi)(shi)驗(yan)(yan)記(ji)錄(lu)保存對話框，做(zuo)(zuo)出(chu)選擇(ze)后(hou)，該次試(shi)(shi)驗(yan)(yan)完(wan)畢。

2、自動升壓模式

開機(ji)后(hou)，進入主(zhu)菜單，旋動(dong)(dong)設置控制桿使光(guang)標指向“自(zi)動(dong)(dong)升(sheng)壓"選項，點(dian)擊(ji)控制桿，進入自(zi)動(dong)(dong)模式參(can)數(shu)設置界面(mian)，根據具體的試驗(yan)要求設置各(ge)項參(can)數(shu)后(hou)，即(ji)可(ke)進入升(sheng)壓界面(mian)。此時，按(an)下高壓通按(an)鈕后(hou)，系統將開始自(zi)動(dong)(dong)升(sheng)壓，升(sheng)至試驗(yan)電壓設定(ding)值(zhi)后(hou)，穩壓并開始計時，計時完畢(bi)后(hou)系統將會自(zi)動(dong)(dong)降壓回零，然后(hou)彈出試驗(yan)記錄(lu)保存對(dui)話框，做出選擇(ze)后(hou)，該次試驗(yan)完畢(bi)。

3、MOA升壓測試模式

開(kai)機后，進入(ru)主菜(cai)單，旋動設(she)(she)置控(kong)制桿(gan)(gan)使光(guang)標指向“MOA升壓(ya)(ya)"選(xuan)項(xiang)，點擊控(kong)制桿(gan)(gan)，進入(ru)自(zi)動模(mo)式參數(shu)設(she)(she)置界(jie)(jie)面，根據具體的(de)試(shi)驗(yan)要(yao)求(qiu)設(she)(she)置各項(xiang)參數(shu)后，即可進入(ru)升壓(ya)(ya)界(jie)(jie)面。此時(shi)(shi)，按(an)下高壓(ya)(ya)通按(an)鈕后，系(xi)統(tong)將(jiang)開(kai)始自(zi)動升壓(ya)(ya)，升至(zhi)試(shi)驗(yan)電流設(she)(she)定值后，穩流并開(kai)始計(ji)時(shi)(shi)，計(ji)時(shi)(shi)完畢后系(xi)統(tong)自(zi)動降壓(ya)(ya)至(zhi)原來(lai)電壓(ya)(ya)值的(de)0.75倍，穩壓(ya)(ya)并重新(xin)開(kai)始計(ji)時(shi)(shi)，計(ji)時(shi)(shi)完畢后系(xi)統(tong)將(jiang)會自(zi)動降壓(ya)(ya)回(hui)零，彈出(chu)試(shi)驗(yan)記錄保存對話框(kuang)，做出(chu)選(xuan)擇(ze)后，該次試(shi)驗(yan)完畢。試(shi)驗(yan)結(jie)束后，界(jie)(jie)面返(fan)回(hui)到主菜(cai)單界(jie)(jie)面，先用(yong)放電棒充分放電后，再關閉電源。

4、試驗(yan)完(wan)畢，關閉電源開關。

5、對(dui)于氧化鋅(xin)避(bi)雷器(qi)等(deng)小(xiao)電(dian)容試(shi)品(pin)一(yi)般(ban)通(tong)過倍壓(ya)筒內部測(ce)壓(ya)電(dian)阻放(fang)電(dian)即可。而對(dui)電(dian)纜等(deng)大電(dian)容試(shi)品(pin)須安(an)裝配(pei)套限流電(dian)阻，一(yi)般(ban)要待(dai)試(shi)品(pin)電(dian)壓(ya)自放(fang)電(dian)至試(shi)驗電(dian)壓(ya)的(de)20%以下，再(zai)通(tong)過配(pei)套的(de)放(fang)電(dian)棒進行(xing)放(fang)電(dian)。待(dai)試(shi)品(pin)充分放(fang)電(dian)后并掛好接(jie)地線(xian)，才(cai)允許(xu)進行(xing)高壓(ya)引線(xian)的(de)拆除和更(geng)換接(jie)線(xian)工(gong)作。
