一、 高頻300KV直流高壓發生器/分體設計主要技術性能：
對試(shi)品進行泄漏及直流耐壓試(shi)驗
⑴ 在做負載試(shi)驗前，將高壓屏蔽微安(an)(an)(an)表(biao)安(an)(an)(an)裝到倍壓筒上的高壓輸出端上，并將配(pei)套的專用高壓線分別接到微安(an)(an)(an)表(biao)上和(he)被試(shi)品上。
⑵ 檢查儀器、放(fang)**、倍壓(ya)(ya)筒、試(shi)品聯接(jie)線、接(jie)地線是否正(zheng)確(que)，接(jie)地線聯接(jie)是否可靠(kao)，檢查高壓(ya)(ya)安(an)全距(ju)離是否符合要求(qiu)，方可開(kai)始進行試(shi)品的高壓(ya)(ya)試(shi)驗。
⑶ 檢查確認(ren)儀器等無(wu)異常(chang)情(qing)況后，接(jie)通(tong)單相交流220V電源開關，此時綠燈(deng)亮，表示電源接(jie)通(tong)。可開始進(jin)行試品的直流泄漏和(he)直流耐壓試驗。
⑷ 按(an)紅色按(an)鈕，則紅燈(deng)亮，表示高(gao)壓接通，待升高(gao)壓。
⑸ 順(shun)時(shi)針方(fang)向平緩調節(jie)調壓(ya)電(dian)(dian)(dian)(dian)位器,輸(shu)出端即從零開始升(sheng)壓(ya)。升(sheng)壓(ya)速度以每秒3-5kV上升(sheng)試驗電(dian)(dian)(dian)(dian)壓(ya)為宜(yi)。對于大(da)電(dian)(dian)(dian)(dian)容試品(pin)升(sheng)壓(ya)時(shi)則(ze)需要緩慢升(sheng)壓(ya)，否則(ze)可能(neng)導致電(dian)(dian)(dian)(dian)壓(ya)過沖,還需監視電(dian)(dian)(dian)(dian)流(liu)表(biao)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)不(bu)超過直流(liu)發(fa)生(sheng)器的*大(da)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)。當升(sheng)到所需的電(dian)(dian)(dian)(dian)壓(ya)或電(dian)(dian)(dian)(dian)流(liu)后，按(an)規定時(shi)間記錄電(dian)(dian)(dian)(dian)流(liu)表(biao)及電(dian)(dian)(dian)(dian)壓(ya)表(biao)的讀數(shu)。
⑹ 試驗完畢(bi)后(hou)(hou)，降壓，將調壓電位器(qi)回零后(hou)(hou)，隨后(hou)(hou)按綠色按鈕，切斷高壓并(bing)關閉電源開關。
⑺ 試(shi)驗完(wan)畢后(hou)(hou)，應用(yong)(yong)放(fang)**對(dui)試(shi)品(pin)進(jin)行多次放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)(hou)方(fang)可(ke)(ke)靠近試(shi)品(pin)和拆線工作(zuo) (放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)請詳細見放(fang)**使用(yong)(yong)說(shuo)明書)。對(dui)小(xiao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)試(shi)品(pin)如(ru)氧(yang)化鋅避(bi)雷器(qi)、磁(ci)吹避(bi)雷器(qi)等緩緩調(diao)節調(diao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)升(sheng)壓(ya)(ya)到(dao)(dao)(dao)所需(xu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu))值(zhi)，然(ran)后(hou)(hou)從數顯表上(shang)讀出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu))數值(zhi)。如(ru)需(xu)對(dui)氧(yang)化鋅避(bi)雷器(qi)進(jin)行75%VDC-1mA的(de)(de)測量時(shi)(shi)(shi)，應先升(sheng)到(dao)(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)到(dao)(dao)(dao)1000uA時(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)停止(這時(shi)(shi)(shi)可(ke)(ke)記(ji)錄(lu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值(zhi))，然(ran)后(hou)(hou)按(an)(an)(an)(an)(an)下黃色(se)按(an)(an)(an)(an)(an)鈕(niu)(niu),電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)即降到(dao)(dao)(dao)原來的(de)(de)75%,并保持此(ci)狀態(tai)。此(ci)時(shi)(shi)(shi)可(ke)(ke)讀取微安表數值(zhi)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)。測量完(wan)畢后(hou)(hou),調(diao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)逆(ni)時(shi)(shi)(shi)針回到(dao)(dao)(dao)零(ling)位(wei),按(an)(an)(an)(an)(an)下綠(lv)色(se)按(an)(an)(an)(an)(an)鈕(niu)(niu),需(xu)再(zai)次升(sheng)壓(ya)(ya)時(shi)(shi)(shi)按(an)(an)(an)(an)(an)紅色(se)按(an)(an)(an)(an)(an)鈕(niu)(niu)即可(ke)(ke)。對(dui)大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)試(shi)品(pin)時(shi)(shi)(shi)，升(sheng)壓(ya)(ya)應更要緩慢(man)，并需(xu)要監(jian)視電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不超過發(fa)生器(qi)的(de)(de)*大充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，一(yi)定要放(fang)慢(man)升(sheng)壓(ya)(ya)速度,避(bi)免充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過大。試(shi)驗完(wan)畢后(hou)(hou)，將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)調(diao)節電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)逆(ni)時(shi)(shi)(shi)針回到(dao)(dao)(dao)零(ling)位(wei)上(shang)，隨(sui)后(hou)(hou)按(an)(an)(an)(an)(an)綠(lv)色(se)按(an)(an)(an)(an)(an)鈕(niu)(niu)，切(qie)斷高(gao)壓(ya)(ya)。此(ci)時(shi)(shi)(shi)注意電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)表上(shang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)降到(dao)(dao)(dao)20kV左右,方(fang)可(ke)(ke)用(yong)(yong)放(fang)**進(jin)行多次放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，確保安全。
4、在使用過(guo)程中發現紅燈滅，綠燈亮，直流高(gao)壓下(xia)降，即為有關保護動(dong)作。此時(shi)應按下(xia)列步驟操作:
