智能高壓驗電器工作(zuo)原理(li)：

帶電(dian)導體(ti)上的電(dian)子會轉(zhuan)移到驗(yan)電(dian)器上，移走帶電(dian)導體(ti)，驗(yan)電(dian)器金屬箔繼續張開。

智能高壓驗電器注意事項：

1、使用前(qian)根據(ju)被(bei)驗電設備的額定(ding)電壓等(deng)級，選擇(ze)對應的驗電器；

2、驗(yan)電(dian)(dian)(dian)前對(dui)驗(yan)電(dian)(dian)(dian)器進行(xing)自檢試驗(yan)。須同時按住(zhu)自檢開關和觸(chu)(chu)電(dian)(dian)(dian)探針，驗(yan)電(dian)(dian)(dian)指示器發(fa)(fa)出間(jian)歇(xie)振蕩聲(sheng)(sheng)光訊號(hao)，則驗(yan)電(dian)(dian)(dian)器性(xing)能完(wan)好，可進行(xing)驗(yan)電(dian)(dian)(dian)，此時可將絕緣桿連續(xu)伸開，進行(xing)驗(yan)電(dian)(dian)(dian)操(cao)作，手(shou)不能過黑色把(ba)套，驗(yan)電(dian)(dian)(dian)器接觸(chu)(chu)頭(tou)與等級的(de)帶電(dian)(dian)(dian)體接觸(chu)(chu)，可發(fa)(fa)出間(jian)歇(xie)聲(sheng)(sheng)光訊號(hao)表示有電(dian)(dian)(dian)，否則表示無電(dian)(dian)(dian)；

3、更換(huan)電(dian)池(chi)。在(zai)驗電(dian)器(qi)頭與桿連(lian)接(jie)處擰開，把驗電(dian)器(qi)下面與桿連(lian)接(jie)處的螺絲(si)擰開，可更換(huan)電(dian)池(chi)。本產品在(zai)工作后(hou)自動關(guan)(guan)閉，有信號輸(shu)入則開啟，無信號便(bian)自動關(guan)(guan)閉，功耗小，不(bu)需要(yao)常換(huan)電(dian)池(chi)。采(cai)用Ag13號氧化銀電(dian)池(chi)4粒，電(dian)壓6V。自檢不(bu)能發出聲光(guang)訊號時(shi)再考慮(lv)更換(huan)電(dian)池(chi)；

4、定期做(zuo)試驗(yan)(yan)。驗(yan)(yan)電(dian)(dian)器在電(dian)(dian)器設備(bei)上(shang)驗(yan)(yan)電(dian)(dian)時要遵照工(gong)作規程(cheng)。試驗(yan)(yan)前(qian)，應進行(xing)外(wai)觀檢查。當發現驗(yan)(yan)電(dian)(dian)指示器的外(wai)殼有缺(que)損(sun)，絕緣桿有裂紋等不(bu)進行(xing)試驗(yan)(yan)，及(ji)時更換。

5、驗電器各部(bu)分的連接牢(lao)靠；指示器密封完好(hao)，表面光滑、平(ping)整，指示器上的標志完整；絕緣桿內外表面清潔、光滑，無(wu)劃痕等。

6、驗電(dian)(dian)時，應(ying)(ying)(ying)使用(yong)相(xiang)應(ying)(ying)(ying)等級的驗電(dian)(dian)器，在(zai)裝置接(jie)地(di)線(xian)或接(jie)地(di)刀閘(zha)處對各相(xiang)分別驗電(dian)(dian)。驗電(dian)(dian)前(qian)應(ying)(ying)(ying)先在(zai)有電(dian)(dian)設備上進行試驗，確證驗電(dian)(dian)器良好(hao)。

7、高壓(ya)驗(yan)電應戴(dai)絕緣(yuan)(yuan)手(shou)(shou)套(tao)。驗(yan)電器的絕緣(yuan)(yuan)桿要伸展(zhan)開，驗(yan)電時手(shou)(shou)應握在手(shou)(shou)柄處不得過黑色(se)把套(tao)。
