简述直流高压发生器操作步骤及故障技巧排查方法

直(zhi)流高压发生器操作说(shuo)明故障技巧(qiao)排查:
  (1)控制(zhi)箱(xiang)上的显示灯(deng)、开关、旋钮等(deng)已(yi)标清楚 ，看此(ci)操作说(shuo)明(ming)时请参照控制(zhi)箱(xiang)的面板上元器件名称使用
  (2)高压塔底盘侧面(mian)之七芯(xin)插座为联(lian)接控制箱(xiang)电缆之插座，底盘侧面(mian)有铜接线柱为接地端子作连接地线用。
  (3)随附有高(gao)压屏蔽电(dian)(dian)流表为数显微安表，表顶(ding)端上的(de)插孔为连(lian)接(jie)被试品(pin)线的(de)插孔，同时(shi)也作为电(dian)(dian)源(yuan)开(kai)关，不用(yong)(yong)时(shi)请拔(ba)掉插头，就(jiu)自(zi)动并闭电(dian)(dian)源(yuan)。。换电(dian)(dian)池时(shi)请用(yong)(yong)镙丝(si)刀打开(kai)上盖，换好后请扣好盖用(yong)(yong)镙丝(si)拧紧。扁圆表换电(dian)(dian)池时(shi)打开(kai)后盖。
1、将控制箱面板上(shang)的(de)接地(di)(di)(di)端子与(yu)高压塔的(de)接地(di)(di)(di)接线(xian)柱(zhu)用接地(di)(di)(di)线(xian)连接在一起并与(yu)现场或试验室(shi)的(de)地(di)(di)(di)线(xian)接牢。为(wei)保(bao)证(zheng)您与(yu)设备的(de)安全，请(qing)务必(bi)反复检查地(di)(di)(di)线(xian)，确保(bao)各部接地(di)(di)(di)良好。
用(yong)(yong)提供的七芯电缆连(lian)接控制箱与高(gao)压塔，电缆两端(duan)为(wei)同样的快速航空插头，注(zhu)意(yi)用(yong)(yong)插头侧(ce)面豁口对准插座(zuo)内侧(ce)粗(cu)凸部(bu)分插入并(bing)顺(shun)时针拧紧。（可用(yong)(yong)电缆任一端(duan)连(lian)接控制箱或(huo)高(gao)压塔）接好(hao)电源(yuan)(yuan)线，电源(yuan)(yuan)为(wei)单项工(gong)频交流220V。
2、打(da)开(kai)(kai)电(dian)(dian)源(yuan)开(kai)(kai)关(guan)，此时电(dian)(dian)源(yuan)开(kai)(kai)关(guan)灯（绿）和面板表(biao)亮。打(da)开(kai)(kai)高(gao)压(ya)(ya)(ya)开(kai)(kai)关(guan)，则(ze)高(gao)压(ya)(ya)(ya)指示(shi)(shi)灯（绿）亮，如高(gao)压(ya)(ya)(ya)提示(shi)(shi)蜂鸣(ming)器(qi)处(chu)在(zai)(zai)开(kai)(kai)的位置，则(ze)鸣(ming)叫以提示(shi)(shi)操作者在(zai)(zai)加高(gao)压(ya)(ya)(ya)，此时，顺(shun)时针旋转高(gao)压(ya)(ya)(ya)输出调节钮(niu)，则(ze)升高(gao)压(ya)(ya)(ya)，电(dian)(dian)压(ya)(ya)(ya)表(biao)显示(shi)(shi)为负载试(shi)品上(shang)(shang)的电(dian)(dian)压(ya)(ya)(ya)KV值，电(dian)(dian)流(liu)表(biao)则(ze)显示(shi)(shi)试(shi)品上(shang)(shang)流(liu)过的电(dian)(dian)流(liu)与所有(you)泄(xie)漏电(dian)(dian)流(liu)之和但不包括(kuo)内(nei)置高(gao)压(ya)(ya)(ya)分压(ya)(ya)(ya)器(qi)的电(dian)(dian)流(liu)。电(dian)(dian)流(liu)是微(wei)安值。
    如(ru)果打开(kai)电源开(kai)关(guan)(guan)，并打开(kai)高(gao)压开(kai)关(guan)(guan)时，高(gao)压显示灯(deng)（绿）不(bu)亮，且故障显示中"回零(ling)(ling)"灯(deng)（红）亮时则表示高(gao)压输出调节钮未(wei)在零(ling)(ling)位，请逆(ni)时针旋钮至"回零(ling)(ling)"灯(deng)灭，再顺时针调节即可(ke)升压。
3、直流高(gao)压(ya)(ya)(ya)发生器若不(bu)需(xu)要额(e)定(ding)(ding)输出(chu)电(dian)(dian)压(ya)(ya)(ya)范围内的(de)调压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)时，要把过(guo)(guo)(guo)压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)整定(ding)(ding)钮顺时针旋至zui大值。此时，当输出(chu)电(dian)(dian)压(ya)(ya)(ya)超过(guo)(guo)(guo)额(e)定(ding)(ding)输出(chu)电(dian)(dian)压(ya)(ya)(ya)时即(ji)自(zi)动保(bao)(bao)(bao)护(hu)，切断(duan)高(gao)压(ya)(ya)(ya)。若要求在额(e)定(ding)(ding)输出(chu)电(dian)(dian)压(ya)(ya)(ya)范围内进(jin)行(xing)调压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)时，请空载升压(ya)(ya)(ya)按以上(shang)步(bu)骤升压(ya)(ya)(ya)到预定(ding)(ding)的(de)保(bao)(bao)(bao)护(hu)电(dian)(dian)压(ya)(ya)(ya)上(shang)，再将过(guo)(guo)(guo)压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)整定(ding)(ding)旋钮慢慢逆时针旋转到所需(xu)要的(de)电(dian)(dian)压(ya)(ya)(ya)上(shang)，作(zuo)过(guo)(guo)(guo)压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)动作(zuo)，"过(guo)(guo)(guo)压(ya)(ya)(ya)"指示灯亮(liang)，保(bao)(bao)(bao)持过(guo)(guo)(guo)压(ya)(ya)(ya)保(bao)(bao)(bao)护(hu)整定(ding)(ding)旋钮定(ding)(ding)于此位(wei)置，将升压(ya)(ya)(ya)旋钮回到零(ling)位(wei)上(shang)，关闭电(dian)(dian)源。接上(shang)试品，则以后升压(ya)(ya)(ya)超过(guo)(guo)(guo)预定(ding)(ding)电(dian)(dian)压(ya)(ya)(ya)时即(ji)切断(duan)高(gao)压(ya)(ya)(ya)。
4、当(dang)发(fa)生过(guo)压、过(guo)流等故障(zhang)时，高(gao)(gao)(gao)压自动切(qie)断，高(gao)(gao)(gao)压显(xian)示灯(deng)（绿）灭，蜂呜器停止鸣叫，相应(ying)故障(zhang)指(zhi)示灯(deng)亮(liang)，说明是(shi)品已短路，若要重(zhong)(zhong)新启动时，应(ying)将高(gao)(gao)(gao)压输出调(diao)(diao)整(zheng)钮(niu)回零(ling)位，微调(diao)(diao)旋钮(niu)同(tong)样(yang)在零(ling)位上(shang)，，再(zai)关(guan)电(dian)源(yuan)开(kai)关(guan)，然后再(zai)打开(kai)电(dian)源(yuan)开(kai)关(guan)才能切(qie)除保(bao)护重(zhong)(zhong)新升(sheng)压。
    (1).正(zheng)常工(gong)作关机时，应(ying)先将高压调整旋钮逆时回到零位上，再将微调旋钮回到零位上，zui后关闭电源开关。
    (2).电源(yuan)开关(guan)兼用于保(bao)护重(zhong)置开关(guan)，当故障显示(shi)灯（回(hui)零显示(shi)灯除外）亮后应关(guan)闭电源(yuan)开关(guan)再打(da)开才能(neng)解除保(bao)护，重(zhong)新升压(ya)。
5、直流(liu)高(gao)(gao)压(ya)发生器负(fu)载(zai)(zai)为大容(rong)性负(fu)载(zai)(zai)时(shi)，为避免充(chong)电电流(liu)过大而(er)触发过流(liu)保护，请(qing)适(shi)当放(fang)慢升压(ya)速度。试验(yan)完毕后，将输出(chu)电压(ya)调(diao)整钮逆时(shi)针旋至零位，关闭高(gao)(gao)压(ya)开(kai)关，此时(shi)电压(ya)表仍显(xian)示(shi)试品(pin)上的电压(ya)值，请(qing)等试品(pin)通过高(gao)(gao)压(ya)塔(ta)放(fang)电至20KV以下时(shi)再用接地(di)棒放(fang)电，以确(que)保安全。
