使用方(fang)法及注意(yi)事項

使用驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)時(shi)必(bi)須注意其(qi)額定電(dian)(dian)(dian)(dian)(dian)(dian)壓和被檢(jian)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)氣設(she)備(bei)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓等(deng)級相適應，否則(ze)(ze)可(ke)能會危及驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)操作人(ren)(ren)員的(de)人(ren)(ren)身安全或(huo)造成誤判(pan)斷。驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)操作人(ren)(ren)員應戴絕緣手套，手握在(zai)罩(zhao)護環(huan)以(yi)下(xia)的(de)握手部(bu)(bu)位(wei)，先在(zai)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)上(shang)進(jin)行(xing)檢(jian)驗(yan)(yan)(yan)(yan)(yan)，檢(jian)驗(yan)(yan)(yan)(yan)(yan)時(shi)應漸(jian)(jian)漸(jian)(jian)將驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)移(yi)近(jin)帶電(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)至發光或(huo)發聲(sheng)時(shi)止，以(yi)確認驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)性能完好(hao)，有(you)自(zi)(zi)檢(jian)系統的(de)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)應先撳(qin)動(dong)自(zi)(zi)檢(jian)鈕(niu)確認驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)完好(hao)，然(ran)后再在(zai)需(xu)要進(jin)行(xing)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)的(de)設(she)備(bei)上(shang)檢(jian)測，檢(jian)測時(shi)也應漸(jian)(jian)漸(jian)(jian)將驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)移(yi)近(jin)待測設(she)備(bei)，直至觸(chu)及設(she)備(bei)導電(dian)(dian)(dian)(dian)(dian)(dian)部(bu)(bu)位(wei)，此過程(cheng)(cheng)若一直無聲(sheng)、光指示，則(ze)(ze)可(ke)判(pan)定該設(she)備(bei)不(bu)帶電(dian)(dian)(dian)(dian)(dian)(dian)，反之，如(ru)在(zai)移(yi)近(jin)過程(cheng)(cheng)中突然(ran)發光或(huo)發聲(sheng)，即認為該設(she)備(bei)帶電(dian)(dian)(dian)(dian)(dian)(dian)，即可(ke)停止移(yi)近(jin)，結束驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)。 另(ling)外(wai)(wai)，風車型驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只適用于戶內或(huo)戶外(wai)(wai)良好(hao)天(tian)氣下(xia)使用，凡雨、雪等(deng)環(huan)境(jing)條件下(xia)，禁(jin)止使用。 　
(1)用高壓驗電器進(jin)行測(ce)試時(shi)，必須戴(dai)上符合要求的絕緣手(shou)套;不(bu)可一個人(ren)(ren)單獨測試(shi)，身旁必須有(you)人(ren)(ren)監護;測試(shi)時，要(yao)防(fang)止發生(sheng)相間或對地短(duan)路事故;人體(ti)與帶(dai)電體(ti)應(ying)保持足夠的安全距(ju)離，10kV高壓的安全距(ju)離(li)為0. 7 m以(yi)上.室(shi)外(wai)使(shi)用時，天(tian)氣(qi)必須(xu)良好，雨、雪、霧及濕度較大(da)的(de)天(tian)氣(qi)中不宜使(shi)用普通絕緣桿的(de)類型，以防發生危險。 　　

(2)使用前，要按所(suo)測設備(線路)的(de)電壓等級將絕緣棒拉(la)伸(shen)至規定(ding)長度，選(xuan)用合適型號的(de)指示器和絕緣棒，并(bing)對(dui)指示器進行檢查，投人使用的(de)高壓驗(yan)電器必須是(shi)經電氣試驗(yan)合格的(de)。 　　

(3)對回(hui)轉式高壓驗電器，使(shi)用(yong)前應把檢驗過的指示器旋接(jie)在絕(jue)緣棒上固(gu)定，并用(yong)綢布將其表面擦拭(shi)干凈，然后(hou)轉動至所需角度(du)，以便使(shi)用(yong)時觀察方便。 　　

(4)對(dui)電容(rong)式(shi)高壓驗(yan)電器，絕緣棒上標有紅線(xian)，紅線(xian)以上部分表(biao)示內有電容(rong)元(yuan)件，且屬帶電部分，該(gai)部分要按《電業安全工作規程》的要求(qiu)與臨近導體或接地體保持必(bi)要的安全距離。 

(5)使用時，應特別注意手握部位不(bu)得超過(guo)護(hu)環

(6)用回(hui)轉式高(gao)壓驗(yan)電器(qi)時，指示(shi)器(qi)的金(jin)屬觸頭(tou)應逐漸靠(kao)近(jin)被測設(she)備(或導線)，一旦指示器(qi)葉片(pian)(pian)(pian)開始正常回轉(zhuan)，則說明該(gai)設(she)備有電(dian)(dian)，應隨即離(li)開被測設(she)備。葉片(pian)(pian)(pian)不能長期回轉(zhuan)，以保證(zheng)驗電(dian)(dian)器(qi)的使用壽命。當電(dian)(dian)纜或電(dian)(dian)容上存在殘余電(dian)(dian)荷(he)電(dian)(dian)壓時，指示器(qi)葉片(pian)(pian)(pian)會短(duan)時緩(huan)慢(man)轉(zhuan)幾圈，而后自(zi)行停轉(zhuan)，因此它(ta)可以準(zhun)確鑒別設(she)備是(shi)否停電(dian)(dian)。 　　

(7)對線路的(de)驗(yan)電(dian)(dian)應(ying)逐(zhu)相(xiang)進行(xing)，對聯絡(luo)用的(de)斷(duan)路器或隔離開關或其(qi)他檢修設(she)備驗(yan)電(dian)(dian)時(shi)，應(ying)在其(qi)進出線兩側(ce)各相(xiang)分(fen)別驗(yan)電(dian)(dian)。對同桿塔架設(she)的(de)多層電(dian)(dian)力線路進行(xing)驗(yan)電(dian)(dian)時(shi)，先驗(yan)低壓、后驗(yan)高壓，先驗(yan)下層、后驗(yan)上(shang)層。 　　

(8)在電容器組上驗電應待其放電完畢后再進行(xing)。 　　

(9)每次使用完畢(bi)，在收(shou)縮絕緣棒及取下回轉指(zhi)示器(qi)放人包裝袋之前，應將表面塵埃擦拭(shi)干凈，并存放在干燥(zao)通(tong)風的地方，以免受潮。回轉指(zhi)示器(qi)應妥(tuo)善保管，不得強烈(lie)振(zhen)動或沖擊，也不準擅自調整拆裝。 　　

(10)為保證(zheng)使用安全，驗電器應每(mei)半年進(jin)行一次(ci)預防性(xing)電氣試驗。
