產品簡(jian)介

ZGF系列直流高壓試驗器是揚州豪泰公司充分吸取用戶的寶貴意見，潛心研究而推出的新一代產品。在保留了ZGFⅡ一些特點的基礎上，作了如下重大改進：①采用了電壓大反饋，因此輸出電壓穩定度得到大幅度提高，電壓漂移量極小；②大幅度提高了頻率，使紋波系數更小；③增設了高精度0.75UDC-1mA 功能按鈕，給氧化鋅避雷器測量帶來了極大的方便；

④高(gao)壓過壓整(zheng)定(ding)(ding)(ding)采(cai)用(yong)數(shu)字(zi)撥盤開關，能將(jiang)整(zheng)定(ding)(ding)(ding)電壓值直(zhi)觀顯示，并(bing)具有較高(gao)的整(zheng)定(ding)(ding)(ding)精度；⑤輸(shu)出電壓調節采(cai)用(yong)單個多圈(quan)電位(wei)器，升壓過程平穩，調節精度高(gao)，操作簡(jian)單；⑥與(yu)此同時，根據電磁(ci)兼容(rong)性(xing)理論，采(cai)用(yong)特殊屏蔽(bi)、隔(ge)離和接地等措施從而保證試驗器能承受(shou)額定(ding)(ding)(ding)電壓放電不損壞。

ZGF 系列采用了*的一體化機(ji)箱(xiang)結構。使(shi)用時倍壓與控(kong)制箱(xiang)可分(fen)離(li)，既方便攜帶(dai)，又安全可靠。體積重量大(da)為減少。

本試驗器(qi)廣泛適用于對氧(yang)化鋅避雷器(qi)、磁吹避雷器(qi)、電(dian)(dian)力電(dian)(dian)纜、發(fa)電(dian)(dian)機、變壓器(qi)、開關等(deng)設備進(jin)行直流高壓試驗。

五(wu)、使用(yong)前準備

⑴ 直流發生器(qi)在使(shi)用前應檢查其完好性,聯接電(dian)纜(lan)線不(bu)應有斷路和短路，設備無破裂等損壞。

⑵將機箱、倍壓筒放置到(dao)合適的安全的位(wei)(wei)置，分別聯(lian)接(jie)(jie)好電源(yuan)線(xian)(xian)(xian)、電纜線(xian)(xian)(xian)和接(jie)(jie)地(di)(di)(di)線(xian)(xian)(xian)。保(bao)護接(jie)(jie)地(di)(di)(di)線(xian)(xian)(xian)與工(gong)作接(jie)(jie)地(di)(di)(di)線(xian)(xian)(xian)以及放**的接(jie)(jie)地(di)(di)(di)線(xian)(xian)(xian)均應單獨接(jie)(jie)到(dao)試(shi)品(pin)的地(di)(di)(di)線(xian)(xian)(xian)上(shang)(即一(yi)點接(jie)(jie)地(di)(di)(di))并確保(bao)接(jie)(jie)地(di)(di)(di)良好。嚴禁各接(jie)(jie)地(di)(di)(di)線(xian)(xian)(xian)相互(hu)串聯(lian)使用，以免(mian)擊(ji)穿時地(di)(di)(di)電位(wei)(wei)抬(tai)高(gao)形成反(fan)擊(ji)，損壞儀(yi)器。

⑶ 檢查(cha)電(dian)源開(kai)關(guan)(guan)是否在(zai)關(guan)(guan)斷的位(wei)置(zhi)上(shang)，并檢查(cha)調(diao)壓(ya)電(dian)位(wei)器應在(zai)零位(wei)上(shang),過電(dian)壓(ya)保(bao)護(hu)整定撥(bo)盤開(kai)關(guan)(guan)設置(zhi)在(zai)適(shi)當的位(wei)置(zhi)上(shang)，一般為(wei)1.10～1.20倍測試(shi)電(dian)壓(ya)值。

2、空載升壓驗證過電壓保護整定(ding)值

⑴ 請認準電(dian)源是單相交流220V，50Hz.接(jie)通電(dian)源開關(guan),此時綠燈亮(liang),表(biao)示(shi)電(dian)源接(jie)通。

⑵ 按(an)紅(hong)色按(an)鈕，則紅(hong)燈(deng)亮(liang)，表示高(gao)壓(ya)接通。

⑶ 順時(shi)針(zhen)方向(xiang)平緩調(diao)節調(diao)壓電位器(qi)，輸出端即從(cong)零開始(shi)升(sheng)壓。電壓表顯示(shi)為負載試(shi)品上(shang)的(de)電壓（KV）值，電流(liu)表則(ze)顯示(shi)試(shi)品上(shang)流(liu)過(guo)的(de)電流(liu)與(yu)所有(you)泄漏(lou)電流(liu)之和，電流(liu)以微安(an)（uA）為單位。升(sheng)到所需的(de)電壓后，按規定時(shi)間記錄電流(liu)表讀數(shu)，并檢(jian)查控制箱(xiang)及(ji)輸出電纜有(you)無異常現(xian)象及(ji)聲響。

⑵ 檢查儀器、放(fang)**、倍壓(ya)(ya)(ya)筒、試品聯接(jie)(jie)線(xian)(xian)、接(jie)(jie)地(di)(di)線(xian)(xian)是(shi)(shi)(shi)否正確，接(jie)(jie)地(di)(di)線(xian)(xian)聯接(jie)(jie)是(shi)(shi)(shi)否可靠(kao)，檢查高壓(ya)(ya)(ya)安全距離是(shi)(shi)(shi)否符合要求，方可開始進行試品的高壓(ya)(ya)(ya)試驗(yan)。

⑶ 檢查確認儀器等無異常情況后(hou)，接通單相交流220V電源開(kai)關，此時綠燈(deng)亮，表示(shi)電源接通。可開(kai)始進行試品的直流泄漏和直流耐壓試驗。

⑷ 按紅色按鈕(niu)，則紅燈亮，表示高(gao)壓(ya)接通，待升高(gao)壓(ya)。

⑸ 順時針(zhen)方(fang)向平緩調(diao)節調(diao)壓(ya)電(dian)(dian)(dian)(dian)位器,輸出端即從零開始升壓(ya)。升壓(ya)速度以每秒3-5kV上升試(shi)(shi)驗電(dian)(dian)(dian)(dian)壓(ya)為宜。對于(yu)大電(dian)(dian)(dian)(dian)容試(shi)(shi)品升壓(ya)時則(ze)需要緩慢升壓(ya)，否(fou)則(ze)可能導致(zhi)電(dian)(dian)(dian)(dian)壓(ya)過(guo)沖,還需監視電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不超過(guo)直流(liu)(liu)(liu)發(fa)生器的(de)*大充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。當(dang)升到(dao)所需的(de)電(dian)(dian)(dian)(dian)壓(ya)或電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)后(hou)，按規定時間記錄(lu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)及電(dian)(dian)(dian)(dian)壓(ya)表(biao)的(de)讀數。

⑹ 試驗(yan)完畢后，降壓(ya)(ya)，將調壓(ya)(ya)電(dian)位(wei)器回零后，隨后按綠色按鈕(niu)，切斷(duan)高(gao)壓(ya)(ya)并關閉電(dian)源開關。

⑺ 試驗(yan)完畢(bi)(bi)后(hou)，應(ying)用放**對試品(pin)進行(xing)多次放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)后(hou)方可(ke)靠近試品(pin)和拆(chai)線工(gong)作(zuo) (放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)請詳細見放**使用說明書(shu))。對小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容試品(pin)如(ru)氧化鋅(xin)避雷(lei)器(qi)、磁吹(chui)避雷(lei)器(qi)等緩緩調(diao)節(jie)調(diao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)升(sheng)(sheng)(sheng)壓(ya)(ya)到(dao)(dao)所(suo)需的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu))值(zhi)(zhi)，然(ran)后(hou)從數(shu)顯表(biao)上讀(du)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu))數(shu)值(zhi)(zhi)。如(ru)需對氧化鋅(xin)避雷(lei)器(qi)進行(xing)75%VDC-1mA的測量時(shi)(shi)，應(ying)先升(sheng)(sheng)(sheng)到(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)到(dao)(dao)1000uA時(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)(zhi)停止(這時(shi)(shi)可(ke)記錄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)值(zhi)(zhi))，然(ran)后(hou)按(an)下黃色(se)按(an)鈕,電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)即(ji)降(jiang)到(dao)(dao)原來的75%,并(bing)保(bao)持此(ci)(ci)狀態。此(ci)(ci)時(shi)(shi)可(ke)讀(du)取微安表(biao)數(shu)值(zhi)(zhi)及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)值(zhi)(zhi)。測量完畢(bi)(bi)后(hou),調(diao)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)逆時(shi)(shi)針回(hui)到(dao)(dao)零(ling)位(wei),按(an)下綠(lv)色(se)按(an)鈕,需再次升(sheng)(sheng)(sheng)壓(ya)(ya)時(shi)(shi)按(an)紅色(se)按(an)鈕即(ji)可(ke)。對大(da)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容試品(pin)時(shi)(shi)，升(sheng)(sheng)(sheng)壓(ya)(ya)應(ying)更要(yao)緩慢，并(bing)需要(yao)監視電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不超過發生器(qi)的*大(da)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)，一定要(yao)放慢升(sheng)(sheng)(sheng)壓(ya)(ya)速度,避免充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)過大(da)。試驗(yan)完畢(bi)(bi)后(hou)，將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)調(diao)節(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)位(wei)器(qi)逆時(shi)(shi)針回(hui)到(dao)(dao)零(ling)位(wei)上，隨后(hou)按(an)綠(lv)色(se)按(an)鈕，切斷高壓(ya)(ya)。此(ci)(ci)時(shi)(shi)注意(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)表(biao)上的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)降(jiang)到(dao)(dao)20kV左(zuo)右,方可(ke)用放**進行(xing)多次放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，確保(bao)安全。

六、注意事項

1、為確保人身安全，在此反(fan)復提醒(xing)用戶注意控制箱及(ji)倍(bei)壓(ya)筒的良好接地以及(ji)停機(ji)后的試品(pin)及(ji)倍(bei)壓(ya)筒放電問題。

2、防止(zhi)異物進入控制箱，如(ru)控制箱有風(feng)扇時，應經常檢查風(feng)扇是否正(zheng)常運轉。

3、當倍(bei)壓筒絕緣(yuan)筒臟污時請用干布擦(ca)凈，不可(ke)用酒精，汽油等有(you)機(ji)類(lei)溶劑(ji)擦(ca)洗。可(ke)用洗滌劑(ji)清洗絕緣(yuan)筒表面，等風(feng)干后方(fang)可(ke)使用，運輸或不使用時請放(fang)。
