使用方法及(ji)注(zhu)意事項
使(shi)用(yong)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器時(shi)(shi)必須注意其額(e)定電(dian)(dian)(dian)(dian)壓和(he)被檢(jian)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)氣設(she)(she)(she)(she)備(bei)(bei)(bei)的(de)電(dian)(dian)(dian)(dian)壓等(deng)級相適應(ying)(ying),否則可(ke)能會危及驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)操作(zuo)(zuo)人員(yuan)(yuan)的(de)人身安(an)全或(huo)造(zao)成誤判(pan)斷。驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)時(shi)(shi)操作(zuo)(zuo)人員(yuan)(yuan)應(ying)(ying)戴絕(jue)緣手(shou)套,手(shou)握在(zai)(zai)罩護環以下(xia)的(de)握手(shou)部位(wei),先(xian)在(zai)(zai)有(you)(you)電(dian)(dian)(dian)(dian)設(she)(she)(she)(she)備(bei)(bei)(bei)上進(jin)行(xing)檢(jian)驗(yan)(yan)(yan)(yan),檢(jian)驗(yan)(yan)(yan)(yan)時(shi)(shi)應(ying)(ying)漸漸將驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器移(yi)近(jin)帶電(dian)(dian)(dian)(dian)設(she)(she)(she)(she)備(bei)(bei)(bei)至發光或(huo)發聲時(shi)(shi)止,以確認(ren)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器性(xing)能完好,有(you)(you)自檢(jian)系統(tong)的(de)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器應(ying)(ying)先(xian)撳(qin)動(dong)自檢(jian)鈕確認(ren)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器完好,然后再在(zai)(zai)需要進(jin)行(xing)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)的(de)設(she)(she)(she)(she)備(bei)(bei)(bei)上檢(jian)測(ce),檢(jian)測(ce)時(shi)(shi)也應(ying)(ying)漸漸將驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器移(yi)近(jin)待(dai)測(ce)設(she)(she)(she)(she)備(bei)(bei)(bei),直至觸及設(she)(she)(she)(she)備(bei)(bei)(bei)導電(dian)(dian)(dian)(dian)部位(wei),此過程若(ruo)一直無(wu)聲、光指示,則可(ke)判(pan)定該(gai)設(she)(she)(she)(she)備(bei)(bei)(bei)不帶電(dian)(dian)(dian)(dian),反之,如(ru)在(zai)(zai)移(yi)近(jin)過程中突然發光或(huo)發聲,即認(ren)為該(gai)設(she)(she)(she)(she)備(bei)(bei)(bei)帶電(dian)(dian)(dian)(dian),即可(ke)停(ting)止移(yi)近(jin),結束驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)。 另外(wai),風車(che)型驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器只適用(yong)于戶(hu)內或(huo)戶(hu)外(wai)良好天氣下(xia)使(shi)用(yong),凡雨、雪(xue)等(deng)環境(jing)條件(jian)下(xia),禁止使(shi)用(yong)。
(1)用(yong)高壓驗電器進行測試(shi)時,必須戴(dai)上符(fu)合要求(qiu)的絕緣手(shou)套;不(bu)可一(yi)個人(ren)單獨測試,身(shen)旁必須有人(ren)監護;測試時(shi),要防止(zhi)發生(sheng)相間或對地短路事(shi)故(gu);人體(ti)與帶電體(ti)應保持足夠的(de)安全距離,10kV高壓的(de)安全距離為0. 7 m以上(shang).室(shi)外使用(yong)(yong)時,天氣(qi)必須良(liang)好,雨(yu)、雪(xue)、霧及濕度較大的(de)天氣(qi)中不宜使用(yong)(yong)普通絕(jue)緣桿(gan)的(de)類(lei)型,以防發生危險。
(2)使用前,要按所測設備(線路)的電壓等(deng)級將絕(jue)緣棒(bang)拉伸至規定長度,選用(yong)合(he)適型號的指(zhi)示器(qi)和絕(jue)緣棒(bang),并對(dui)指(zhi)示器(qi)進(jin)行檢查(cha),投人使用(yong)的高(gao)壓驗電器(qi)必須是經電氣試驗合(he)格的。
(3)對回轉式高壓驗(yan)電(dian)器,使(shi)用(yong)前應(ying)把檢驗(yan)過的指示器旋(xuan)接在絕(jue)緣(yuan)棒上(shang)固定,并(bing)用(yong)綢布將其表面擦(ca)拭干凈,然后轉動至所需角度,以便(bian)使(shi)用(yong)時觀察方便(bian)。
(4)對電(dian)容式高(gao)壓驗電(dian)器,絕緣棒上(shang)標有紅線,紅線以(yi)上(shang)部(bu)分(fen)(fen)表示內有電(dian)容元件,且屬帶電(dian)部(bu)分(fen)(fen),該部(bu)分(fen)(fen)要(yao)按《電(dian)業安(an)全工作規程》的要(yao)求(qiu)與臨近導體或接地體保持必(bi)要(yao)的安(an)全距離(li)。
(5)使(shi)用時,應特別注意(yi)手(shou)握(wo)部位(wei)不得(de)超過護環
(6)用回轉(zhuan)式高壓驗(yan)電器時,指示器的金屬觸頭應逐漸靠(kao)近被測(ce)設(she)備(bei)(或導(dao)線),一旦指(zhi)示(shi)器葉(xie)片(pian)開始(shi)正常回轉(zhuan),則說(shuo)明該設備(bei)有電(dian),應隨即離開被(bei)測(ce)設備(bei)。葉(xie)片(pian)不能長期回轉(zhuan),以(yi)保證驗電(dian)器的(de)使用壽命。當(dang)電(dian)纜或電(dian)容上存在殘余電(dian)荷(he)電(dian)壓時(shi),指(zhi)示(shi)器葉(xie)片(pian)會短時(shi)緩慢轉(zhuan)幾(ji)圈(quan),而后自行停轉(zhuan),因(yin)此它可以(yi)準(zhun)確鑒(jian)別設備(bei)是否停電(dian)。
