使用方(fang)法及注(zhu)意事項
使用驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)時(shi)必須注(zhu)意其(qi)額定電(dian)(dian)(dian)(dian)壓和(he)被檢(jian)驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)氣(qi)設(she)(she)(she)備(bei)的電(dian)(dian)(dian)(dian)壓等級相適應(ying)(ying),否則可能(neng)(neng)會危及驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)操作人員的人身(shen)安全或造成誤判斷。驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)時(shi)操作人員應(ying)(ying)戴絕緣手套(tao),手握(wo)在罩護環以下(xia)的握(wo)手部(bu)位,先在有(you)電(dian)(dian)(dian)(dian)設(she)(she)(she)備(bei)上(shang)進行檢(jian)驗(yan)(yan)(yan),檢(jian)驗(yan)(yan)(yan)時(shi)應(ying)(ying)漸漸將驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)移(yi)(yi)近(jin)(jin)帶電(dian)(dian)(dian)(dian)設(she)(she)(she)備(bei)至發(fa)光或發(fa)聲時(shi)止,以確認(ren)驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)性能(neng)(neng)完好,有(you)自檢(jian)系統的驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)應(ying)(ying)先撳動(dong)自檢(jian)鈕確認(ren)驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)完好,然后再在需(xu)要進行驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)的設(she)(she)(she)備(bei)上(shang)檢(jian)測(ce),檢(jian)測(ce)時(shi)也應(ying)(ying)漸漸將驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)移(yi)(yi)近(jin)(jin)待測(ce)設(she)(she)(she)備(bei),直至觸及設(she)(she)(she)備(bei)導電(dian)(dian)(dian)(dian)部(bu)位,此過(guo)(guo)程若一(yi)直無聲、光指示(shi),則可判定該設(she)(she)(she)備(bei)不帶電(dian)(dian)(dian)(dian),反之,如(ru)在移(yi)(yi)近(jin)(jin)過(guo)(guo)程中突(tu)然發(fa)光或發(fa)聲,即認(ren)為該設(she)(she)(she)備(bei)帶電(dian)(dian)(dian)(dian),即可停止移(yi)(yi)近(jin)(jin),結(jie)束驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)。 另外,風(feng)車型驗(yan)(yan)(yan)電(dian)(dian)(dian)(dian)器(qi)只適用于(yu)戶內(nei)或戶外良好天氣(qi)下(xia)使用,凡雨、雪等環境條(tiao)件下(xia),禁止使用。
(1)用高壓驗電器進行測試時,必須(xu)戴上符合要求的絕(jue)緣手套;不可一個人(ren)單(dan)獨(du)測試,身旁必(bi)須(xu)有人(ren)監護;測試時,要防(fang)止發生(sheng)相間(jian)或對地短路事故;人體與帶電體應保持足夠的安全距離,10kV高壓的安全距離為0. 7 m以上.室外使用(yong)時,天氣必(bi)須良好,雨、雪、霧及濕(shi)度較(jiao)大(da)的天氣中不宜使用(yong)普(pu)通絕(jue)緣桿的類型,以(yi)防發生危險。
(2)使(shi)用前,要按所測設備(線路)的電壓等級(ji)將絕(jue)緣棒拉伸至規(gui)定長度,選用(yong)合適型號的指示器(qi)(qi)和絕(jue)緣棒,并對指示器(qi)(qi)進(jin)行檢(jian)查,投人(ren)使用(yong)的高壓驗電器(qi)(qi)必須是經電氣(qi)試(shi)驗合格的。
(3)對(dui)回轉(zhuan)式高壓驗電器(qi),使用(yong)前(qian)應把檢驗過的指示(shi)器(qi)旋接在(zai)絕緣棒上(shang)固定,并用(yong)綢布(bu)將其(qi)表面擦拭干凈,然(ran)后轉(zhuan)動至所(suo)需角度(du),以便使用(yong)時觀(guan)察方便。
(4)對電(dian)容式高(gao)壓(ya)驗電(dian)器,絕(jue)緣棒上標有紅(hong)線,紅(hong)線以上部(bu)分表示內(nei)有電(dian)容元(yuan)件,且屬帶電(dian)部(bu)分,該部(bu)分要(yao)(yao)按《電(dian)業安(an)全(quan)(quan)工作規程》的(de)要(yao)(yao)求與臨近導體或(huo)接地體保持必要(yao)(yao)的(de)安(an)全(quan)(quan)距(ju)離。
(5)使用時,應特別注意(yi)手握(wo)部位不得超過護(hu)環
(6)用回(hui)轉式高壓驗電器時,指示器的(de)金屬觸頭應逐(zhu)漸靠近被測設備(或導(dao)線(xian)),一旦指示器葉片(pian)開(kai)始正常回(hui)轉(zhuan)(zhuan),則說明該(gai)設(she)(she)備有電(dian),應隨(sui)即離開(kai)被測(ce)設(she)(she)備。葉片(pian)不(bu)能長期回(hui)轉(zhuan)(zhuan),以(yi)保(bao)證(zheng)驗(yan)電(dian)器的使用壽命。當電(dian)纜(lan)或電(dian)容上存在殘余電(dian)荷(he)電(dian)壓(ya)時(shi),指示器葉片(pian)會(hui)短(duan)時(shi)緩慢轉(zhuan)(zhuan)幾圈,而(er)后自行(xing)停轉(zhuan)(zhuan),因此(ci)它(ta)可以(yi)準確鑒別設(she)(she)備是否停電(dian)。
(7)對(dui)線路(lu)的(de)驗(yan)電(dian)應(ying)逐(zhu)相進(jin)行(xing),對(dui)聯絡用的(de)斷路(lu)器(qi)或(huo)隔離(li)開關或(huo)其(qi)他檢修設(she)備驗(yan)電(dian)時,應(ying)在其(qi)進(jin)出線兩(liang)側各相分別驗(yan)電(dian)。對(dui)同桿塔架設(she)的(de)多層(ceng)電(dian)力(li)線路(lu)進(jin)行(xing)驗(yan)電(dian)時,先驗(yan)低壓、后驗(yan)高壓,先驗(yan)下層(ceng)、后驗(yan)上(shang)層(ceng)。
(8)在電(dian)容器組上驗(yan)電(dian)應(ying)待其放電(dian)完畢后再進行。
(9)每(mei)次使用完畢,在收縮絕緣(yuan)棒及(ji)取下回轉(zhuan)指示(shi)器放(fang)人包裝袋(dai)之前,應將表面(mian)塵埃擦拭干(gan)凈,并(bing)存(cun)放(fang)在干(gan)燥通風的地方,以免(mian)受潮(chao)。回轉(zhuan)指示(shi)器應妥善保管,不(bu)得強烈振動或沖擊,也不(bu)準(zhun)擅自調整拆裝。
(10)為保證使用安全,驗電器應每半年進行(xing)一次(ci)預防性電氣試驗。
