產品概述
產品概述:
60KV/120KV/200KV直流高壓發生器,是根(gen)據新的中(zhong)國電(dian)(dian)力待業標準(zhun)DL/T848.1-2004《直(zhi)流(liu)耐(nai)(nai)壓(ya)(ya)試驗(yan)裝(zhuang)置(zhi)通用(yong)技術條件》設計制造的新一代便攜式(shi)直(zhi)流(liu)耐(nai)(nai)壓(ya)(ya)試驗(yan)裝(zhuang)置(zhi)。主(zhu)要適(shi)用(yong)于電(dian)(dian)力部門、工礦、冶金、鋼(gang)鐵(tie)等(deng)企業動力部門對氧化(hua)鋅避雷器、電(dian)(dian)力電(dian)(dian)纜、變(bian)壓(ya)(ya)器、發電(dian)(dian)機(ji)等(deng)高壓(ya)(ya)電(dian)(dian)氣設備進(jin)行直(zhi)流(liu)耐(nai)(nai)壓(ya)(ya)試驗(yan)。
產(chan)品別稱:直(zhi)高(gao)發(fa)、高(gao)壓發(fa)生器、中頻直(zhi)流高(gao)壓發(fa)生器。
功能說明:
1、控(kong)制(zhi)(zhi)箱(xiang)接地端子(zi):控(kong)制(zhi)(zhi)箱(xiang)接地端子(zi)與(yu)倍壓筒接地端子(zi)及試品接地聯接為一點后再與(yu)接地網相連。
2、高頻及(ji)測量電纜快速(su)聯接(jie)插座:用于機箱與(yu)倍(bei)壓部(bu)分(fen)的聯接(jie)。聯接(jie)時(shi)只(zhi)需將電纜插頭順(shun)時(shi)針方向轉動到位。拆(chai)線時(shi)只(zhi)需逆時(shi)針轉動電纜插頭。
3、電源輸入插(cha)座(zuo)(zuo):將隨機配置的(de)電源線與電源輸入插(cha)座(zuo)(zuo)相(xiang)關。(交(jiao)流220V±10%,插(cha)座(zuo)(zuo)內自來保(bao)險管(guan)。)
4、過壓(ya)整定(ding)撥盤開關:用于設立(li)過電壓(ya)保護值(zhi)。撥盤開關所(suo)顯(xian)示單位為KV,設定(ding)值(zhi)為試(shi)驗電壓(ya)1.1倍(bei)。
5、數(shu)顯電(dian)壓表(biao):數(shu)字顯示(shi)直流高壓輸出電(dian)壓。
6、數顯(xian)電流(liu)表(biao):數字顯(xian)示直流(liu)高(gao)壓輸出電流(liu)。
7、電源開關:向(xiang)前按(an)下,電源接通,綠燈亮。反(fan)之(zhi)為關斷。
8、黃燈(deng)(deng)按鈕(niu)(niu):此(ci)功能(neng)是專門為(wei)氧化鋅避雷器快速測(ce)量0.75UDc1mA用。紅燈(deng)(deng)亮(liang)(liang)時(shi)有效(xiao)。當(dang)按下(xia)黃色按鈕(niu)(niu)后黃燈(deng)(deng)亮(liang)(liang),輸出高(gao)(gao)壓降至(zhi)原來0.75%,并保持此(ci)狀態。按下(xia)綠色按鈕(niu)(niu),紅燈(deng)(deng)、黃燈(deng)(deng)均(jun)滅,高(gao)(gao)壓切斷并退出0.75倍狀態。
9、紅(hong)燈(deng)(deng)按(an)(an)鈕(niu):高(gao)壓(ya)(ya)接通按(an)(an)鈕(niu)、高(gao)壓(ya)(ya)指示燈(deng)(deng)。在綠燈(deng)(deng)亮(liang)的狀態(tai)下(xia),按(an)(an)下(xia)紅(hong)色(se)(se)按(an)(an)鈕(niu)后,紅(hong)燈(deng)(deng)亮(liang)綠燈(deng)(deng)滅,表示高(gao)壓(ya)(ya)回(hui)路接通,此(ci)時可(ke)升壓(ya)(ya)。此(ci)按(an)(an)鈕(niu)須在電壓(ya)(ya)調節電位器回(hui)零狀態(tai)下(xia)才有效。如按(an)(an)下(xia)紅(hong)色(se)(se)按(an)(an)鈕(niu),紅(hong)燈(deng)(deng)亮(liang)綠燈(deng)(deng)仍(reng)亮(liang),但(dan)松開(kai)按(an)(an)鈕(niu)紅(hong)燈(deng)(deng)滅綠燈(deng)(deng)亮(liang),表示機內保護電路已工作。
10、綠色帶燈按(an)鈕:綠燈亮(liang),表示電源已(yi)接通(tong)及高(gao)壓(ya)斷(duan)開。在紅燈亮(liang)狀(zhuang)態下按(an)下綠色按(an)鈕,紅燈滅綠燈亮(liang),高(gao)壓(ya)回路切(qie)斷(duan)。
操作步驟:
1、直(zhi)流耐壓試驗(yan)裝置在(zai)使(shi)用前應檢查其完好性,連(lian)接電(dian)纜(lan)不應有斷路(lu)和短路(lu),設備無破(po)裂(lie)等(deng)損(sun)壞。
2、將機箱(xiang)、倍壓筒放置(zhi)到合適位置(zhi)分別連接(jie)(jie)好(hao)電纜線(xian)(xian)、接(jie)(jie)地(di)線(xian)(xian)和電源線(xian)(xian),保護接(jie)(jie)地(di)線(xian)(xian)與工作接(jie)(jie)地(di)線(xian)(xian)以及放電棒(bang)的(de)接(jie)(jie)地(di)線(xian)(xian)均應(ying)單獨接(jie)(jie)到試品的(de)地(di)線(xian)(xian)上(shang)(即一點接(jie)(jie)地(di))。嚴禁各(ge)接(jie)(jie)地(di)線(xian)(xian)相互串(chuan)聯,為(wei)此,應(ying)使用(yong)ZGF接(jie)(jie)地(di)線(xian)(xian)。
3、電源(yuan)開關放在關斷位(wei)置并檢(jian)查調壓電位(wei)器(qi)應在零位(wei)。過電壓保護整定(ding)值一般為試驗(yan)電壓的1.1倍。
4、空(kong)載升壓(ya)檢測過電(dian)壓(ya)保護整(zheng)定是否靈敏。
5、接(jie)通電源開(kai)關,此時綠燈亮,表(biao)示電源接(jie)通。
6、60KV/120KV/200KV直流高壓發生器按紅色按鈕,則紅燈亮,表示高壓接通。
7、順時(shi)(shi)針方向平緩(huan)調節調壓(ya)電位(wei)器,輸出端(duan)即從零開始升壓(ya),升至所(suo)需電壓(ya)后,按規定時(shi)(shi)間(jian)記(ji)錄電流(liu)表(biao)讀數,并檢查控制箱及(ji)高壓(ya)輸出線(xian)有(you)無異(yi)常現(xian)象(xiang)及(ji)聲響。
8、降壓(ya),將(jiang)調壓(ya)電位器回(hui)零(ling)后(hou),隨(sui)即按綠(lv)色按鈕(niu),切斷高(gao)壓(ya)并關閉電源(yuan)開關。
9、對試(shi)(shi)(shi)品進(jin)行泄漏(lou)及直流耐(nai)壓(ya)試(shi)(shi)(shi)驗(yan)。在進(jin)行檢查試(shi)(shi)(shi)驗(yan)確認試(shi)(shi)(shi)驗(yan)器無(wu)異常情(qing)況后,即可開(kai)始進(jin)行試(shi)(shi)(shi)品的泄漏(lou)及直流耐(nai)壓(ya)試(shi)(shi)(shi)驗(yan)。將試(shi)(shi)(shi)品、地(di)線等聯接(jie)好,檢查無(wu)誤后即打開(kai)電源。
10、升(sheng)(sheng)(sheng)壓(ya)(ya)(ya)(ya)至(zhi)所(suo)需(xu)(xu)(xu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)或電(dian)(dian)(dian)(dian)流(liu)。升(sheng)(sheng)(sheng)壓(ya)(ya)(ya)(ya)速度以(yi)每(mei)秒35KV試(shi)(shi)驗電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)為宜(yi)。對(dui)于(yu)大電(dian)(dian)(dian)(dian)容試(shi)(shi)品升(sheng)(sheng)(sheng)壓(ya)(ya)(ya)(ya)時(shi)(shi)還需(xu)(xu)(xu)監視電(dian)(dian)(dian)(dian)流(liu)表充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)不超(chao)過試(shi)(shi)驗器(qi)(qi)的大充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)。對(dui)小電(dian)(dian)(dian)(dian)容試(shi)(shi)品如氧化鋅(xin)避雷器(qi)(qi)、磁吹避雷器(qi)(qi)等先升(sheng)(sheng)(sheng)至(zhi)所(suo)需(xu)(xu)(xu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(電(dian)(dian)(dian)(dian)源)的95%,再緩慢仔細升(sheng)(sheng)(sheng)至(zhi)所(suo)需(xu)(xu)(xu)的電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(電(dian)(dian)(dian)(dian)流(liu)),然后從數(shu)顯表上(shang)讀(du)出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(電(dian)(dian)(dian)(dian)流(liu))值.如需(xu)(xu)(xu)對(dui)氧化鋅(xin)避雷器(qi)(qi)進行0.75UDC1mA測量時(shi)(shi),先升(sheng)(sheng)(sheng)至(zhi)UDC~1mA電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)值,然后按(an)下(xia)黃色按(an)鈕(niu),此(ci)時(shi)(shi)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)即降至(zhi)原(yuan)來的75%,并保持此(ci)狀態。此(ci)時(shi)(shi)可讀(du)取微(wei)安數(shu)。測量完畢后,調壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)位器(qi)(qi)逆時(shi)(shi)針回(hui)到(dao)零按(an)下(xia)綠色按(an)鈕(niu)。需(xu)(xu)(xu)再次升(sheng)(sheng)(sheng)壓(ya)(ya)(ya)(ya)時(shi)(shi)按(an)紅色按(an)鈕(niu)即可。
必(bi)要時用外接(jie)高壓分壓器(qi)比對控制(zhi)箱上(shang)的直流高壓指示。
