使(shi)用驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時必須注意其額定(ding)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)被檢(jian)(jian)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣設(she)備(bei)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)等級相適應，否則可(ke)(ke)能會危及(ji)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)操作人(ren)員的人(ren)身安全或造成誤(wu)判(pan)斷。驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時操作人(ren)員應戴絕緣手套，手握在(zai)(zai)罩護環以(yi)下(xia)的握手部(bu)位(wei)(wei)，先在(zai)(zai)有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)上進行(xing)檢(jian)(jian)驗(yan)，檢(jian)(jian)驗(yan)時應漸(jian)(jian)漸(jian)(jian)將驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)移(yi)近(jin)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)備(bei)至發(fa)(fa)光或發(fa)(fa)聲(sheng)時止(zhi)，以(yi)確認(ren)(ren)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)性(xing)能完好，有自檢(jian)(jian)系(xi)統的驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)應先撳動自檢(jian)(jian)鈕確認(ren)(ren)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)完好，然(ran)后再在(zai)(zai)需要進行(xing)驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的設(she)備(bei)上檢(jian)(jian)測(ce)，檢(jian)(jian)測(ce)時也應漸(jian)(jian)漸(jian)(jian)將驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)移(yi)近(jin)待測(ce)設(she)備(bei)，直至觸及(ji)設(she)備(bei)導電(dian)(dian)(dian)(dian)(dian)(dian)(dian)部(bu)位(wei)(wei)，此過程(cheng)若一(yi)直無聲(sheng)、光指示，則可(ke)(ke)判(pan)定(ding)該設(she)備(bei)不帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，反(fan)之，如在(zai)(zai)移(yi)近(jin)過程(cheng)中(zhong)突然(ran)發(fa)(fa)光或發(fa)(fa)聲(sheng)，即(ji)認(ren)(ren)為該設(she)備(bei)帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，即(ji)可(ke)(ke)停止(zhi)移(yi)近(jin)，結束驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。另外，風(feng)車型驗(yan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只適用于戶內(nei)或戶外良好天氣下(xia)使(shi)用，凡雨、雪等環境條件下(xia)，禁止(zhi)使(shi)用。

　　(1)用(yong)高壓(ya)驗(yan)電器進行(xing)測試(shi)時，必(bi)須戴上符合要(yao)求的(de)(de)絕緣(yuan)手套;不可(ke)一個人單獨測試(shi)，身旁必(bi)須有人監護;測試(shi)時，要(yao)防(fang)(fang)止發(fa)生相間或(huo)對地短(duan)路事故;人體與帶電體應保持足夠的(de)(de)安(an)全(quan)距離，10kV高壓(ya)的(de)(de)安(an)全(quan)距離為0.7m以上.室外使用(yong)時，天(tian)氣必(bi)須良好，雨、雪、霧及(ji)濕(shi)度較大(da)的(de)(de)天(tian)氣中不宜使用(yong)普通絕緣(yuan)桿的(de)(de)類型，以防(fang)(fang)發(fa)生危險。

　　(2)使用前(qian)，要按(an)所測設備(bei)(線路)的(de)電(dian)(dian)壓等級(ji)將絕緣棒拉伸至規定長度，選用合適(shi)型號的(de)指示(shi)器和絕緣棒，并對指示(shi)器進行檢(jian)查，投人使用的(de)高壓驗電(dian)(dian)器必(bi)須是經電(dian)(dian)氣試驗合格的(de)。

　　(3)對回轉式(shi)高(gao)壓(ya)驗電器，使用(yong)(yong)前應把(ba)檢驗過的指示器旋接(jie)在絕緣棒上固定，并(bing)用(yong)(yong)綢布將(jiang)其表面擦拭干凈，然后(hou)轉動至所(suo)需(xu)角度，以便使用(yong)(yong)時(shi)觀察(cha)方(fang)便。

　　(4)對電(dian)(dian)(dian)容式高壓驗(yan)電(dian)(dian)(dian)器，絕緣棒上標(biao)有紅(hong)線，紅(hong)線以上部分表示內(nei)有電(dian)(dian)(dian)容元件，且屬帶電(dian)(dian)(dian)部分，該(gai)部分要按(an)《電(dian)(dian)(dian)業(ye)安全工作規程》的要求與臨近導體或接地體保(bao)持(chi)必要的安全距離。

　　(5)使用時(shi)，應(ying)特(te)別(bie)注意手握部位不得超過護環(huan)

　　(6)用回(hui)(hui)轉式高壓驗電(dian)(dian)器(qi)時(shi)(shi)，指(zhi)(zhi)示器(qi)的金屬觸頭應(ying)逐漸靠近被(bei)測設(she)(she)(she)備(bei)(或導線)，一旦指(zhi)(zhi)示器(qi)葉片開(kai)始正常回(hui)(hui)轉，則說明該設(she)(she)(she)備(bei)有電(dian)(dian)，應(ying)隨即離開(kai)被(bei)測設(she)(she)(she)備(bei)。葉片不能長(chang)期回(hui)(hui)轉，以(yi)保證驗電(dian)(dian)器(qi)的使用壽命。當電(dian)(dian)纜(lan)或電(dian)(dian)容上存在殘余電(dian)(dian)荷電(dian)(dian)壓時(shi)(shi)，指(zhi)(zhi)示器(qi)葉片會短(duan)時(shi)(shi)緩慢轉幾圈，而后(hou)自行停轉，因(yin)此它(ta)可以(yi)準確(que)鑒別設(she)(she)(she)備(bei)是否停電(dian)(dian)。

　　(7)對線路的驗(yan)(yan)電(dian)應逐(zhu)相進行，對聯(lian)絡用的斷路器或(huo)隔離開關或(huo)其他(ta)檢修設備驗(yan)(yan)電(dian)時，應在其進出線兩側各相分別驗(yan)(yan)電(dian)。對同桿塔(ta)架(jia)設的多層電(dian)力(li)線路進行驗(yan)(yan)電(dian)時，先(xian)驗(yan)(yan)低壓(ya)、后(hou)驗(yan)(yan)高壓(ya)，先(xian)驗(yan)(yan)下(xia)層、后(hou)驗(yan)(yan)上層。

　　(8)在電容器組上驗電應待其放電完畢后再進行。

　　(9)每次使用完畢，在(zai)收縮絕緣棒及取(qu)下回轉指(zhi)示器(qi)放人包裝袋之(zhi)前，應將表面塵埃擦拭干凈，并存放在(zai)干燥(zao)通風(feng)的地(di)方，以免(mian)受潮。回轉指(zhi)示器(qi)應妥善保管，不得強烈振(zhen)動或沖擊，也不準擅(shan)自調整(zheng)拆裝。

　　(10)為保證(zheng)使用安全，驗電器應每(mei)半年(nian)進行一(yi)次預(yu)防(fang)性電氣試驗。
