多功能高壓安全試驗設備工作(zuo)原理：

帶(dai)電(dian)導(dao)體上的電(dian)子會轉移到驗(yan)(yan)電(dian)器上，移走帶(dai)電(dian)導(dao)體，驗(yan)(yan)電(dian)器金屬箔繼續張開。

多功能高壓安全試驗設備注意事項：

1、使(shi)用前根據被驗電設備的額定電壓等級，選擇(ze)對應(ying)的驗電器；

2、驗(yan)電(dian)(dian)(dian)(dian)前對驗(yan)電(dian)(dian)(dian)(dian)器進(jin)行(xing)自檢(jian)試驗(yan)。須同時按住(zhu)自檢(jian)開關和觸(chu)電(dian)(dian)(dian)(dian)探針，驗(yan)電(dian)(dian)(dian)(dian)指示器發(fa)出(chu)間歇振(zhen)蕩聲光(guang)訊(xun)號(hao)，則(ze)(ze)驗(yan)電(dian)(dian)(dian)(dian)器性能完好(hao)，可(ke)進(jin)行(xing)驗(yan)電(dian)(dian)(dian)(dian)，此時可(ke)將(jiang)絕(jue)緣桿連續伸開，進(jin)行(xing)驗(yan)電(dian)(dian)(dian)(dian)操作，手(shou)不(bu)能過(guo)黑色把(ba)套，驗(yan)電(dian)(dian)(dian)(dian)器接觸(chu)頭與(yu)等級(ji)的帶(dai)電(dian)(dian)(dian)(dian)體接觸(chu)，可(ke)發(fa)出(chu)間歇聲光(guang)訊(xun)號(hao)表(biao)示有電(dian)(dian)(dian)(dian)，否則(ze)(ze)表(biao)示無電(dian)(dian)(dian)(dian)；

3、更(geng)換(huan)(huan)電(dian)(dian)池。在驗(yan)電(dian)(dian)器(qi)(qi)頭與(yu)(yu)桿連接(jie)處(chu)擰(ning)開(kai)(kai)，把驗(yan)電(dian)(dian)器(qi)(qi)下面與(yu)(yu)桿連接(jie)處(chu)的螺絲(si)擰(ning)開(kai)(kai)，可更(geng)換(huan)(huan)電(dian)(dian)池。本產品在工作(zuo)后自動關(guan)(guan)閉(bi)，有信(xin)號輸入則開(kai)(kai)啟，無信(xin)號便自動關(guan)(guan)閉(bi)，功耗(hao)小，不需要常換(huan)(huan)電(dian)(dian)池。采用Ag13號氧化(hua)銀電(dian)(dian)池4粒，電(dian)(dian)壓6V。自檢不能發出(chu)聲光訊號時再考慮(lv)更(geng)換(huan)(huan)電(dian)(dian)池；

4、定(ding)期做試驗(yan)(yan)。驗(yan)(yan)電(dian)器(qi)(qi)在電(dian)器(qi)(qi)設備上驗(yan)(yan)電(dian)時(shi)要遵照工作(zuo)規(gui)程(cheng)。試驗(yan)(yan)前，應進行外觀檢查。當發現驗(yan)(yan)電(dian)指示器(qi)(qi)的外殼有缺損，絕緣桿(gan)有裂紋等不進行試驗(yan)(yan)，及時(shi)更換(huan)。

5、驗電器(qi)各(ge)部分的連(lian)接牢靠；指示器(qi)密封(feng)完好，表(biao)面(mian)(mian)光滑、平整，指示器(qi)上的標志完整；絕緣(yuan)桿(gan)內(nei)外表(biao)面(mian)(mian)清潔、光滑，無劃痕等(deng)。

6、驗(yan)電(dian)時，應(ying)(ying)使用相應(ying)(ying)等級的(de)驗(yan)電(dian)器(qi)，在裝置接地線(xian)或接地刀(dao)閘(zha)處對各相分別驗(yan)電(dian)。驗(yan)電(dian)前應(ying)(ying)先在有電(dian)設備上進行試驗(yan)，確證(zheng)驗(yan)電(dian)器(qi)良好(hao)。

7、高(gao)壓驗電應戴絕緣(yuan)手(shou)套(tao)(tao)。驗電器的絕緣(yuan)桿要伸展開，驗電時手(shou)應握在手(shou)柄處不(bu)得過黑(hei)色(se)把套(tao)(tao)。
