一、 全新直流高壓測試儀/靜電發生器主要技術性能：
對試(shi)品進(jin)行(xing)泄(xie)漏及直流耐壓試(shi)驗
⑴ 在做負載試(shi)驗前(qian)，將高(gao)壓(ya)屏(ping)蔽微安表安裝到倍壓(ya)筒上的高(gao)壓(ya)輸出端(duan)上，并將配(pei)套的專用(yong)高(gao)壓(ya)線分別接到微安表上和被試(shi)品上。
⑵ 檢查(cha)儀器、放(fang)**、倍(bei)壓筒、試品(pin)聯(lian)接線(xian)、接地(di)線(xian)是(shi)否正確，接地(di)線(xian)聯(lian)接是(shi)否可靠，檢查(cha)高(gao)(gao)壓安全距離是(shi)否符合要求(qiu)，方(fang)可開(kai)始(shi)進行試品(pin)的高(gao)(gao)壓試驗。
⑶ 檢查確認(ren)儀(yi)器(qi)等(deng)無異常(chang)情況后，接(jie)通單相交流220V電源開(kai)關，此時綠(lv)燈(deng)亮，表(biao)示(shi)電源接(jie)通。可開(kai)始進行試品(pin)的直(zhi)流泄漏和直(zhi)流耐壓試驗(yan)。
⑷ 按(an)紅色按(an)鈕，則紅燈亮(liang)，表示高壓接(jie)通，待升高壓。
⑸ 順(shun)時針方向平緩調節調壓(ya)電(dian)(dian)位器(qi),輸(shu)出(chu)端即從零開(kai)始(shi)升(sheng)壓(ya)。升(sheng)壓(ya)速度以每秒3-5kV上升(sheng)試(shi)驗電(dian)(dian)壓(ya)為宜。對(dui)于大電(dian)(dian)容試(shi)品升(sheng)壓(ya)時則需(xu)要(yao)緩慢(man)升(sheng)壓(ya)，否則可(ke)能導致電(dian)(dian)壓(ya)過(guo)沖,還需(xu)監視電(dian)(dian)流表充(chong)電(dian)(dian)電(dian)(dian)流不超過(guo)直流發生器(qi)的*大充(chong)電(dian)(dian)電(dian)(dian)流。當(dang)升(sheng)到所(suo)需(xu)的電(dian)(dian)壓(ya)或電(dian)(dian)流后(hou)，按(an)規(gui)定時間記錄電(dian)(dian)流表及電(dian)(dian)壓(ya)表的讀(du)數。
⑹ 全新直流高壓測試儀/靜電發生器試驗完畢后，降壓，將調壓電位器回零后，隨后按綠色按鈕，切斷高壓并關閉電源開關。
⑺ 試(shi)(shi)驗完(wan)畢后(hou)，應(ying)用(yong)放**對(dui)試(shi)(shi)品(pin)進行多次(ci)(ci)放電(dian)(dian)(dian)(dian)，放電(dian)(dian)(dian)(dian)后(hou)方可(ke)靠(kao)近試(shi)(shi)品(pin)和拆線工作 (放電(dian)(dian)(dian)(dian)請詳細見(jian)放**使用(yong)說(shuo)明書)。對(dui)小(xiao)電(dian)(dian)(dian)(dian)容(rong)(rong)試(shi)(shi)品(pin)如(ru)氧化(hua)鋅(xin)避(bi)雷器(qi)、磁吹(chui)避(bi)雷器(qi)等緩(huan)(huan)(huan)緩(huan)(huan)(huan)調節(jie)調壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)位器(qi)升(sheng)壓(ya)(ya)(ya)到(dao)所需(xu)的電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(電(dian)(dian)(dian)(dian)流(liu))值(zhi)，然后(hou)從(cong)數顯(xian)表上讀出電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(電(dian)(dian)(dian)(dian)流(liu))數值(zhi)。如(ru)需(xu)對(dui)氧化(hua)鋅(xin)避(bi)雷器(qi)進行75%VDC-1mA的測(ce)量(liang)時(shi)(shi)，應(ying)先升(sheng)到(dao)電(dian)(dian)(dian)(dian)流(liu)到(dao)1000uA時(shi)(shi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)停(ting)止(zhi)(這(zhe)時(shi)(shi)可(ke)記錄電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)、電(dian)(dian)(dian)(dian)流(liu)值(zhi))，然后(hou)按(an)下黃色(se)按(an)鈕,電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)即降到(dao)原(yuan)來的75%,并(bing)保持(chi)此狀態。此時(shi)(shi)可(ke)讀取微安表數值(zhi)及電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)值(zhi)。測(ce)量(liang)完(wan)畢后(hou),調壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)位器(qi)逆時(shi)(shi)針(zhen)回到(dao)零(ling)位,按(an)下綠色(se)按(an)鈕,需(xu)再次(ci)(ci)升(sheng)壓(ya)(ya)(ya)時(shi)(shi)按(an)紅(hong)色(se)按(an)鈕即可(ke)。對(dui)大(da)電(dian)(dian)(dian)(dian)容(rong)(rong)試(shi)(shi)品(pin)時(shi)(shi)，升(sheng)壓(ya)(ya)(ya)應(ying)更要緩(huan)(huan)(huan)慢，并(bing)需(xu)要監視電(dian)(dian)(dian)(dian)流(liu)表充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)不超過發(fa)生器(qi)的*大(da)充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)，一定要放慢升(sheng)壓(ya)(ya)(ya)速度,避(bi)免充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)過大(da)。4、在使用過程中發(fa)現紅燈(deng)(deng)滅，綠燈(deng)(deng)亮，直流(liu)高壓下(xia)降，即為有關保護動作。此(ci)時應(ying)按下(xia)列步(bu)驟(zou)操作:
⑴ 將調壓電(dian)位器退回零位。
⑵ 關(guan)閉電源開關(guan),面(mian)板指(zhi)示燈均不亮。
⑶ 一分鐘后(hou),待機內低壓電(dian)容器充分放電(dian)后(hou)，才允(yun)許再次打開電(dian)源開關。
