FDB型放電棒

FDB高壓放(fang)電棒

高(gao)壓放(fang)電(dian)棒(bang)是(shi)利用(yong)新(xin)型絕(jue)緣材料(liao)加工而成(cheng)。它具有能拉長(chang)，又能收縮的特(te)點。便(bian)(bian)攜式伸(shen)縮型高(gao)壓放(fang)電(dian)棒(bang)便(bian)(bian)于在室外各項高(gao)電(dian)壓試驗(yan)中(zhong)使用(yong)，特(te)別在做(zuo)直流耐壓試驗(yan)后，對試品上積累的電(dian)荷，進行對地(di)放(fang)電(dian)，確保(bao)人身(shen)安(an)(an)全。伸(shen)縮型高(gao)壓放(fang)電(dian)棒(bang)便(bian)(bian)于攜帶，方(fang)便(bian)(bian)、靈活，具有體積小、重量輕(qing)、安(an)(an)全。

   放電棒使用方法

1、將便攜式伸縮(suo)型高壓放電棒伸縮(suo)部(bu)分全部(bu)拉(la)出。 　　

2、把(ba)配制好的接地線插(cha)(cha)頭(tou)插(cha)(cha)入放電棒的頭(tou)端(duan)部位的插(cha)(cha)孔內(nei)，將地線的另一端(duan)與大(da)地連接，接地要可靠(kao)。 　　

3、放電時(shi)應在試驗完畢后，即直流發生器的控制箱的升壓(ya)旋鈕回到零位上，此(ci)時(shi)可(ke)觀察直流高壓(ya)發生器控制箱上的電壓(ya)表的電壓(ya)下降到15kV～20kV左右，方可(ke)放電。 　　

4、放(fang)(fang)(fang)電(dian)(dian)時應先用放(fang)(fang)(fang)電(dian)(dian)棒(bang)的(de)(de)前端(duan)的(de)(de)金屬尖頭(tou)，慢慢的(de)(de)去靠近已斷開試驗電(dian)(dian)源的(de)(de)試品。此時放(fang)(fang)(fang)電(dian)(dian)棒(bang)釋放(fang)(fang)(fang)電(dian)(dian)能是經(jing)過一放(fang)(fang)(fang)電(dian)(dian)電(dian)(dian)阻進行(xing)對(dui)(dui)地放(fang)(fang)(fang)電(dian)(dian)。然(ran)后(hou)再用放(fang)(fang)(fang)電(dian)(dian)棒(bang)上接(jie)地線上的(de)(de)鉤(gou)子(zi)去鉤(gou)住試品，進行(xing)第二次直接(jie)對(dui)(dui)地放(fang)(fang)(fang)電(dian)(dian)。

放電棒注意事項

1、對(dui)大電(dian)(dian)(dian)(dian)(dian)(dian)容試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)放電(dian)(dian)(dian)(dian)(dian)(dian)時，須在(zai)試(shi)(shi)(shi)(shi)(shi)驗完畢后(hou)，斷(duan)開試(shi)(shi)(shi)(shi)(shi)驗電(dian)(dian)(dian)(dian)(dian)(dian)源后(hou)，應(ying)該等待一(yi)段時間后(hou)，使試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)荷通過倍壓(ya)筒及(ji)試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)本身(shen)對(dui)地(di)自放電(dian)(dian)(dian)(dian)(dian)(dian)。此時可觀察(cha)控制箱上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)數在(zai)逐步下(xia)降跌落，當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)表(biao)(biao)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下(xia)降到(dao)較低的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，一(yi)般在(zai)5kV～15kV左(zuo)右，方可用放電(dian)(dian)(dian)(dian)(dian)(dian)棒去逐步移向試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)附近。先通過間隙空氣游(you)離(li)放電(dian)(dian)(dian)(dian)(dian)(dian)，此時可聽到(dao)嘶(si)嘶(si)的(de)聲(sheng)音，當(dang)無聲(sheng)音后(hou)，用放電(dian)(dian)(dian)(dian)(dian)(dian)棒*去碰試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)，zui后(hou)將試(shi)(shi)(shi)(shi)(shi)品(pin)(pin)直接接地(di)放電(dian)(dian)(dian)(dian)(dian)(dian)。 　　

2、大(da)電(dian)容(rong)試(shi)品(pin)積(ji)累(lei)電(dian)荷的(de)大(da)小與試(shi)品(pin)電(dian)容(rong)的(de)大(da)小和(he)施加(jia)電(dian)壓的(de)高(gao)低與時間的(de)長短成正比。 　　

3、對幾公里以上(shang)的(de)高(gao)壓電(dian)纜試驗結束后，放(fang)電(dian)時間一般(ban)都要(yao)很長，且需(xu)多次(ci)反(fan)復放(fang)電(dian)。電(dian)阻容(rong)量要(yao)很大(da)，需(xu)訂購大(da)容(rong)量的(de)放(fang)電(dian)棒。 　　

4、嚴禁未(wei)拉開試驗電(dian)源(yuan)用放電(dian)棒對試品進行放電(dian)。 　　

5、嚴禁用腳踩(cai)及重物擠壓放(fang)電棒，嚴禁折(zhe)彎(wan)、折(zhe)斷放(fang)電棒。 　　

6、嚴禁將放電棒受潮，影響絕(jue)緣強度，應放在干燥的(de)地(di)方。
