FDB高壓放電棒

FDB高(gao)壓放電(dian)(dian)(dian)棒(bang)是利用新型絕(jue)緣材料(liao)加(jia)工而成。它具有能拉(la)長，又(you)能收縮的特(te)點。便(bian)(bian)攜式伸縮型高(gao)壓放電(dian)(dian)(dian)棒(bang)便(bian)(bian)于(yu)在(zai)室外各項高(gao)電(dian)(dian)(dian)壓試驗中使用，特(te)別在(zai)做直流(liu)耐壓試驗后(hou)，對試品上積累的電(dian)(dian)(dian)荷，進行對地放電(dian)(dian)(dian)，確保(bao)人身(shen)安全。伸縮型高(gao)壓放電(dian)(dian)(dian)棒(bang)便(bian)(bian)于(yu)攜帶(dai)，方(fang)便(bian)(bian)、靈(ling)活，具有體積小、重(zhong)量輕、安全。

產品(pin)參數

注(zhu)意事項

　　1.對(dui)大電(dian)(dian)(dian)容試(shi)品(pin)放(fang)(fang)電(dian)(dian)(dian)時(shi),須在(zai)試(shi)驗(yan)完畢后,斷開試(shi)驗(yan)電(dian)(dian)(dian)源后,應該等(deng)待一(yi)段時(shi)間(jian)后,使試(shi)品(pin)上的(de)電(dian)(dian)(dian)荷通過(guo)倍(bei)壓筒及試(shi)品(pin)本身對(dui)地(di)自放(fang)(fang)電(dian)(dian)(dian).此時(shi)可(ke)觀察控制箱上的(de)電(dian)(dian)(dian)壓表(biao)(biao)電(dian)(dian)(dian)壓數在(zai)逐步下降跌落(luo),當電(dian)(dian)(dian)壓表(biao)(biao)下降到較低的(de)電(dian)(dian)(dian)壓,一(yi)般在(zai)5Kv～15Kv左右,方可(ke)用放(fang)(fang)電(dian)(dian)(dian)棒去(qu)(qu)逐步移向試(shi)品(pin)附近.先通過(guo)間(jian)隙空氣(qi)游離(li)放(fang)(fang)電(dian)(dian)(dian),此時(shi)可(ke)聽到嘶嘶的(de)聲音(yin),當無聲音(yin)后,用放(fang)(fang)電(dian)(dian)(dian)棒**去(qu)(qu)碰試(shi)品(pin),**將試(shi)品(pin)直接接地(di)放(fang)(fang)電(dian)(dian)(dian).

  2.大(da)電容試品積累電荷的(de)(de)大(da)小與試品電容的(de)(de)大(da)小和施(shi)加電壓的(de)(de)高低與時間的(de)(de)長短成(cheng)正比.

  3.對(dui)幾公(gong)里(li)以上的高(gao)壓電(dian)纜試(shi)驗結(jie)束后,放(fang)電(dian)時間(jian)一般都很長,且需多次反(fan)復放(fang)電(dian).電(dian)阻容(rong)量要很大(da),需訂購大(da)容(rong)量的放(fang)電(dian)棒.

  4.嚴禁未拉開試(shi)(shi)驗電源用放(fang)電棒對試(shi)(shi)品進(jin)行放(fang)電.

  5.嚴禁(jin)用腳踩(cai)及重物擠壓放電(dian)棒,嚴禁(jin)折彎(wan),折斷放電(dian)棒.

  6.嚴(yan)禁將放(fang)(fang)電(dian)棒(bang)受(shou)潮,影響絕緣強度,應放(fang)(fang)在干燥的(de)地方.
