使用方(fang)法及注意事項

使(shi)用(yong)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器時(shi)(shi)必須注意其額(e)定(ding)電(dian)(dian)(dian)(dian)壓(ya)和被檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)氣設(she)(she)備(bei)的電(dian)(dian)(dian)(dian)壓(ya)等級相(xiang)適應(ying)，否則(ze)可能(neng)會(hui)危(wei)及驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)操(cao)作人員的人身安全或(huo)(huo)造成誤判斷。驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)時(shi)(shi)操(cao)作人員應(ying)戴絕緣(yuan)手套，手握(wo)在(zai)罩護環以(yi)下的握(wo)手部位(wei)，先在(zai)有(you)電(dian)(dian)(dian)(dian)設(she)(she)備(bei)上(shang)進(jin)行(xing)檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)，檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)時(shi)(shi)應(ying)漸(jian)漸(jian)將驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器移(yi)近帶(dai)電(dian)(dian)(dian)(dian)設(she)(she)備(bei)至發(fa)(fa)光或(huo)(huo)發(fa)(fa)聲(sheng)時(shi)(shi)止(zhi)，以(yi)確認驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器性(xing)能(neng)完(wan)好，有(you)自檢(jian)(jian)(jian)系統的驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器應(ying)先撳動自檢(jian)(jian)(jian)鈕確認驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器完(wan)好，然后再在(zai)需要進(jin)行(xing)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)的設(she)(she)備(bei)上(shang)檢(jian)(jian)(jian)測(ce)，檢(jian)(jian)(jian)測(ce)時(shi)(shi)也應(ying)漸(jian)漸(jian)將驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器移(yi)近待測(ce)設(she)(she)備(bei)，直(zhi)(zhi)至觸及設(she)(she)備(bei)導電(dian)(dian)(dian)(dian)部位(wei)，此過程(cheng)若一(yi)直(zhi)(zhi)無聲(sheng)、光指示(shi)，則(ze)可判定(ding)該設(she)(she)備(bei)不(bu)帶(dai)電(dian)(dian)(dian)(dian)，反之，如在(zai)移(yi)近過程(cheng)中突然發(fa)(fa)光或(huo)(huo)發(fa)(fa)聲(sheng)，即(ji)認為該設(she)(she)備(bei)帶(dai)電(dian)(dian)(dian)(dian)，即(ji)可停止(zhi)移(yi)近，結(jie)束(shu)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)。 另外(wai)(wai)，風車(che)型(xing)驗(yan)(yan)(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器只適用(yong)于戶內或(huo)(huo)戶外(wai)(wai)良好天(tian)氣下使(shi)用(yong)，凡雨、雪等環境條件下，禁止(zhi)使(shi)用(yong)。 　
(1)用高壓驗電器進行(xing)測試時，必須(xu)戴上符合要求的絕(jue)緣手套;不可(ke)一個人單獨(du)測試，身旁必(bi)須有人監護;測試(shi)時，要(yao)防止發生相(xiang)間或對地短路(lu)事故;人體與帶(dai)電體應保持足夠(gou)的安全距離，10kV高壓的安全距離為0. 7 m以(yi)上.室外使用時，天(tian)氣(qi)必須良好(hao)，雨(yu)、雪、霧及濕度較(jiao)大的天(tian)氣(qi)中不宜使用普(pu)通絕(jue)緣桿的類型，以(yi)防發生危險。 　　

(2)使用前，要按所測設備(線路)的電(dian)壓(ya)等級(ji)將絕緣棒拉伸至(zhi)規(gui)定長度(du)，選用合(he)適型號的指(zhi)示器和(he)絕緣棒，并對指(zhi)示器進行檢查，投人使(shi)用的高(gao)壓(ya)驗電(dian)器必須是經電(dian)氣試驗合(he)格的。 　　

(3)對回轉式(shi)高(gao)壓(ya)驗(yan)電(dian)器(qi)，使用前應(ying)把(ba)檢驗(yan)過的(de)指示器(qi)旋接在絕緣棒上(shang)固定，并用綢布將其(qi)表(biao)面擦拭干凈，然后轉動至所需(xu)角度(du)，以(yi)便使用時觀察方便。 　　

(4)對電(dian)(dian)容(rong)式高壓驗電(dian)(dian)器(qi)，絕(jue)緣棒上標有(you)紅線，紅線以上部分表示內有(you)電(dian)(dian)容(rong)元件，且屬帶電(dian)(dian)部分，該(gai)部分要按《電(dian)(dian)業(ye)安(an)全工作規程》的(de)(de)要求與臨(lin)近(jin)導體或接地(di)體保持必要的(de)(de)安(an)全距離。 

(5)使用時(shi)，應特別注意手握部位不得超過護環

(6)用回轉式高壓驗電器時，指示(shi)器的金屬觸頭應逐漸靠近被測設備(或(huo)導(dao)線)，一(yi)旦指示器(qi)葉(xie)片(pian)開始正常(chang)回(hui)轉(zhuan)，則說明(ming)該設(she)(she)備有電(dian)，應隨即離開被測設(she)(she)備。葉(xie)片(pian)不能長期回(hui)轉(zhuan)，以保(bao)證(zheng)驗(yan)電(dian)器(qi)的(de)使用壽命。當(dang)電(dian)纜(lan)或電(dian)容上存在殘余電(dian)荷(he)電(dian)壓時，指示器(qi)葉(xie)片(pian)會短時緩(huan)慢轉(zhuan)幾圈，而后自行停轉(zhuan)，因此(ci)它可以準確鑒別設(she)(she)備是否停電(dian)。 　　

(7)對線路的(de)(de)驗(yan)電應(ying)逐相進行(xing)，對聯絡用的(de)(de)斷路器或隔離(li)開關或其他檢修(xiu)設備驗(yan)電時(shi)，應(ying)在(zai)其進出線兩(liang)側各相分別驗(yan)電。對同桿塔架設的(de)(de)多層(ceng)電力線路進行(xing)驗(yan)電時(shi)，先(xian)驗(yan)低壓(ya)、后(hou)驗(yan)高壓(ya)，先(xian)驗(yan)下層(ceng)、后(hou)驗(yan)上(shang)層(ceng)。 　　

(8)在電(dian)(dian)容器(qi)組上驗(yan)電(dian)(dian)應待其放電(dian)(dian)完畢后(hou)再(zai)進行。 　　

(9)每次使(shi)用完畢，在收縮絕緣棒及取下(xia)回轉指示器放人包裝袋之前，應(ying)將表面塵埃擦拭干凈(jing)，并(bing)存放在干燥通風的(de)地方，以免受潮。回轉指示器應(ying)妥善保管，不得強烈振動(dong)或(huo)沖擊，也(ye)不準(zhun)擅自(zi)調整拆裝。 　　

(10)為保證使用安全，驗電器應每半年(nian)進(jin)行一次預防性電氣試驗。
