使用方(fang)法及注(zhu)意事項

使用驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器時(shi)必須注(zhu)意其額定(ding)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和被檢(jian)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)氣設(she)(she)備(bei)(bei)的電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)等級相適應，否則可能會危及(ji)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)操作人員的人身安全或(huo)造(zao)成誤判斷。驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)時(shi)操作人員應戴絕緣手套(tao)，手握(wo)在罩護(hu)環以(yi)下的握(wo)手部位，先在有電(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)上進行(xing)檢(jian)驗(yan)(yan)，檢(jian)驗(yan)(yan)時(shi)應漸(jian)漸(jian)將驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器移近帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)至發光或(huo)發聲(sheng)時(shi)止(zhi)(zhi)，以(yi)確(que)認(ren)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器性(xing)能完(wan)好(hao)，有自檢(jian)系(xi)統的驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器應先撳動自檢(jian)鈕確(que)認(ren)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器完(wan)好(hao)，然后再(zai)在需要進行(xing)驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)的設(she)(she)備(bei)(bei)上檢(jian)測(ce)，檢(jian)測(ce)時(shi)也應漸(jian)漸(jian)將驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器移近待測(ce)設(she)(she)備(bei)(bei)，直至觸及(ji)設(she)(she)備(bei)(bei)導(dao)電(dian)(dian)(dian)(dian)(dian)部位，此過程若一直無聲(sheng)、光指示，則可判定(ding)該(gai)設(she)(she)備(bei)(bei)不帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)，反之，如(ru)在移近過程中突然發光或(huo)發聲(sheng)，即認(ren)為該(gai)設(she)(she)備(bei)(bei)帶(dai)(dai)電(dian)(dian)(dian)(dian)(dian)，即可停止(zhi)(zhi)移近，結束驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)。 另外，風(feng)車型驗(yan)(yan)電(dian)(dian)(dian)(dian)(dian)器只(zhi)適用于戶(hu)內(nei)或(huo)戶(hu)外良好(hao)天氣下使用，凡雨(yu)、雪(xue)等環境(jing)條(tiao)件下，禁止(zhi)(zhi)使用。 　
(1)用高(gao)壓驗電器進(jin)行(xing)測試(shi)時，必須戴上符(fu)合要求的(de)絕緣手套;不(bu)可一個人(ren)(ren)單獨測試(shi)，身旁必須有(you)人(ren)(ren)監(jian)護(hu);測試時(shi)，要防(fang)止發生相間或對地短路事故;人體與帶電(dian)體應保持足夠的安(an)全距離，10kV高(gao)壓(ya)的安(an)全距離(li)為0. 7 m以(yi)上.室(shi)外使用時(shi)，天氣(qi)必須(xu)良好，雨(yu)、雪、霧及濕度較大的天氣(qi)中不(bu)宜使用普通絕緣桿的類型，以防發生危險。 　　

(2)使(shi)用前，要(yao)按所測設(she)備(線路)的(de)電(dian)壓(ya)等級將絕緣(yuan)棒拉伸至(zhi)規定長度，選用(yong)合適型號的(de)指(zhi)示(shi)器(qi)和絕緣(yuan)棒，并對指(zhi)示(shi)器(qi)進(jin)行(xing)檢(jian)查，投人使用(yong)的(de)高壓(ya)驗電(dian)器(qi)必須是經電(dian)氣試(shi)驗合格的(de)。 　　

(3)對(dui)回(hui)轉(zhuan)式高壓驗電器(qi)，使(shi)用(yong)(yong)前應把檢驗過的(de)指示器(qi)旋接在絕緣棒上(shang)固定，并用(yong)(yong)綢(chou)布將其表面擦拭干凈(jing)，然后轉(zhuan)動至所需(xu)角度，以便使(shi)用(yong)(yong)時觀察(cha)方便。 　　

(4)對電(dian)(dian)容式高(gao)壓驗電(dian)(dian)器，絕緣棒上標有紅線，紅線以上部分表示內有電(dian)(dian)容元件，且(qie)屬(shu)帶電(dian)(dian)部分，該部分要按《電(dian)(dian)業(ye)安(an)全工作規程》的(de)(de)要求與臨近導體(ti)或接地(di)體(ti)保持必要的(de)(de)安(an)全距(ju)離(li)。 

(5)使用時，應特別注意手握部位不得超過護環

(6)用回轉式高(gao)壓驗電器時，指(zhi)示器的金屬(shu)觸頭應逐漸靠近被測設備(或(huo)導線(xian))，一旦(dan)指(zhi)示器(qi)(qi)葉片(pian)開(kai)(kai)始正常回轉，則說明該(gai)設備(bei)有(you)電(dian)，應隨即離開(kai)(kai)被(bei)測設備(bei)。葉片(pian)不能長期回轉，以保證驗電(dian)器(qi)(qi)的使用(yong)壽命。當(dang)電(dian)纜或(huo)電(dian)容上存在(zai)殘余電(dian)荷電(dian)壓時，指(zhi)示器(qi)(qi)葉片(pian)會短時緩慢轉幾(ji)圈，而后自行(xing)停(ting)轉，因此它可以準確鑒別(bie)設備(bei)是否(fou)停(ting)電(dian)。 　　

(7)對線(xian)路的(de)(de)驗(yan)(yan)(yan)(yan)電(dian)應逐相進行，對聯絡用的(de)(de)斷(duan)路器(qi)或(huo)隔離開(kai)關或(huo)其(qi)他檢修(xiu)設(she)(she)備(bei)驗(yan)(yan)(yan)(yan)電(dian)時(shi)，應在其(qi)進出(chu)線(xian)兩側(ce)各相分別驗(yan)(yan)(yan)(yan)電(dian)。對同(tong)桿塔(ta)架設(she)(she)的(de)(de)多層(ceng)電(dian)力線(xian)路進行驗(yan)(yan)(yan)(yan)電(dian)時(shi)，先驗(yan)(yan)(yan)(yan)低壓(ya)、后驗(yan)(yan)(yan)(yan)高(gao)壓(ya)，先驗(yan)(yan)(yan)(yan)下層(ceng)、后驗(yan)(yan)(yan)(yan)上層(ceng)。 　　

(8)在電容器(qi)組上驗(yan)電應待其放(fang)電完畢后再(zai)進行(xing)。 　　

(9)每次使(shi)用(yong)完畢，在收縮(suo)絕緣棒及取下回轉指示(shi)器(qi)放人(ren)包裝(zhuang)(zhuang)袋之前，應(ying)(ying)將(jiang)表面塵埃(ai)擦(ca)拭(shi)干凈，并存放在干燥通風的地(di)方，以免受潮。回轉指示(shi)器(qi)應(ying)(ying)妥善保管(guan)，不得(de)強烈振動(dong)或(huo)沖擊(ji)，也不準擅自調整拆裝(zhuang)(zhuang)。 　　

(10)為保證使用安(an)全(quan)，驗(yan)電(dian)器應每(mei)半年進行一次預防性電(dian)氣試驗(yan)。
