使用方法及注意(yi)事項

使用驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)時(shi)必須注意其(qi)額定電(dian)(dian)(dian)(dian)(dian)(dian)壓和(he)被(bei)檢(jian)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)氣設(she)(she)備(bei)的電(dian)(dian)(dian)(dian)(dian)(dian)壓等級相適應(ying)(ying)，否則可能(neng)會(hui)危及驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)操作人(ren)(ren)員的人(ren)(ren)身安全或(huo)造成誤(wu)判斷。驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)時(shi)操作人(ren)(ren)員應(ying)(ying)戴絕緣手(shou)套，手(shou)握在(zai)(zai)(zai)罩護環以(yi)下(xia)的握手(shou)部(bu)位，先在(zai)(zai)(zai)有(you)電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)上進行(xing)檢(jian)驗(yan)(yan)(yan)(yan)，檢(jian)驗(yan)(yan)(yan)(yan)時(shi)應(ying)(ying)漸(jian)漸(jian)將驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)移(yi)近(jin)帶電(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)至發(fa)(fa)光或(huo)發(fa)(fa)聲(sheng)時(shi)止，以(yi)確認(ren)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)性能(neng)完(wan)好，有(you)自檢(jian)系統(tong)的驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)應(ying)(ying)先撳(qin)動自檢(jian)鈕確認(ren)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)完(wan)好，然后再在(zai)(zai)(zai)需(xu)要(yao)進行(xing)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)的設(she)(she)備(bei)上檢(jian)測(ce)，檢(jian)測(ce)時(shi)也應(ying)(ying)漸(jian)漸(jian)將驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)移(yi)近(jin)待測(ce)設(she)(she)備(bei)，直至觸及設(she)(she)備(bei)導電(dian)(dian)(dian)(dian)(dian)(dian)部(bu)位，此過程(cheng)若一直無(wu)聲(sheng)、光指示，則可判定該設(she)(she)備(bei)不(bu)帶電(dian)(dian)(dian)(dian)(dian)(dian)，反之，如在(zai)(zai)(zai)移(yi)近(jin)過程(cheng)中突(tu)然發(fa)(fa)光或(huo)發(fa)(fa)聲(sheng)，即認(ren)為該設(she)(she)備(bei)帶電(dian)(dian)(dian)(dian)(dian)(dian)，即可停止移(yi)近(jin)，結束(shu)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)。 另外(wai)，風(feng)車型(xing)驗(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只適用于戶(hu)內或(huo)戶(hu)外(wai)良好天(tian)氣下(xia)使用，凡雨、雪等環境(jing)條件下(xia)，禁(jin)止使用。 　
(1)用高(gao)壓驗(yan)電(dian)器進行測試(shi)時(shi)，必須戴(dai)上符合要求的絕(jue)緣手套(tao);不可一個人單獨測試，身旁必須有(you)人監護(hu);測試(shi)時，要防止發生相間或對地短路事(shi)故;人體與(yu)帶電體應保持(chi)足夠的安(an)全距離，10kV高(gao)壓的(de)安全距離為0. 7 m以上.室外使(shi)用(yong)時，天氣(qi)(qi)必須(xu)良好，雨(yu)、雪、霧及濕度較(jiao)大的天氣(qi)(qi)中不(bu)宜(yi)使(shi)用(yong)普通絕緣桿的類型(xing)，以防發生危險。 　　

(2)使用前，要(yao)按所測設(she)備(線路)的(de)電壓等級將絕緣棒(bang)拉伸至規(gui)定長度，選用(yong)合(he)適型號的(de)指示器(qi)和絕緣棒(bang)，并(bing)對指示器(qi)進行(xing)檢查，投人使用(yong)的(de)高(gao)壓驗電器(qi)必須是經電氣試驗合(he)格的(de)。 　　

(3)對回轉式高(gao)壓驗(yan)電(dian)器，使用前(qian)應把檢(jian)驗(yan)過的指示器旋(xuan)接在絕緣(yuan)棒上(shang)固定(ding)，并用綢布將其表面擦拭干凈，然(ran)后轉動至所需角(jiao)度，以便(bian)使用時觀察方便(bian)。 　　

(4)對電(dian)容(rong)式(shi)高壓(ya)驗電(dian)器(qi)，絕緣棒(bang)上標有(you)(you)紅(hong)(hong)線，紅(hong)(hong)線以(yi)上部(bu)分表示內有(you)(you)電(dian)容(rong)元件，且(qie)屬帶電(dian)部(bu)分，該部(bu)分要(yao)按《電(dian)業安全(quan)工作規程》的要(yao)求與臨近導體(ti)或接地體(ti)保持必要(yao)的安全(quan)距離(li)。 

(5)使用(yong)時，應特別注意手握部位(wei)不得超過護環

(6)用(yong)回轉式高壓驗(yan)電器時，指示(shi)器的金(jin)屬觸頭應逐漸靠近被測設(she)備(或導線)，一旦(dan)指(zhi)示(shi)(shi)器(qi)葉(xie)片(pian)開始正(zheng)常(chang)回轉(zhuan)，則(ze)說明(ming)該設備(bei)有電(dian)，應隨即離開被(bei)測設備(bei)。葉(xie)片(pian)不能長期回轉(zhuan)，以保證驗電(dian)器(qi)的(de)使用(yong)壽命。當電(dian)纜或電(dian)容上存在殘余(yu)電(dian)荷電(dian)壓時，指(zhi)示(shi)(shi)器(qi)葉(xie)片(pian)會短時緩慢轉(zhuan)幾圈(quan)，而后自行停轉(zhuan)，因此它可以準確(que)鑒別設備(bei)是否(fou)停電(dian)。 　　

(7)對(dui)線路的驗(yan)(yan)電應逐相進行，對(dui)聯絡用的斷路器或(huo)隔(ge)離(li)開(kai)關或(huo)其他(ta)檢修設備(bei)驗(yan)(yan)電時，應在(zai)其進出(chu)線兩(liang)側各相分別驗(yan)(yan)電。對(dui)同桿塔架設的多層電力線路進行驗(yan)(yan)電時，先驗(yan)(yan)低(di)壓(ya)、后驗(yan)(yan)高壓(ya)，先驗(yan)(yan)下層、后驗(yan)(yan)上層。 　　

(8)在電容器組上驗電應待(dai)其放(fang)電完畢后再進行。 　　

(9)每次使(shi)用完(wan)畢，在收縮絕緣棒及取下(xia)回(hui)轉指示(shi)(shi)器放人包裝(zhuang)袋之前(qian)，應將表面塵埃擦拭干凈，并(bing)存放在干燥(zao)通風的地(di)方，以免受潮。回(hui)轉指示(shi)(shi)器應妥善保管(guan)，不得強(qiang)烈振動或沖擊，也不準擅(shan)自調整拆裝(zhuang)。 　　

(10)為保證(zheng)使(shi)用安全，驗電器(qi)應每半年進行一次預(yu)防性電氣試驗。
