FDB型220KV放電棒
(一)FDB型放電(dian)棒概(gai)述:
在高(gao)壓(ya)(ya)試(shi)驗(yan)領域內,為(wei)了(le)保證高(gao)壓(ya)(ya)試(shi)驗(yan)人員人身安全和設備正常運行(xing),安全措施非常重要(yao)。我廠生產(chan)的(de)FDB型高(gao)壓(ya)(ya)直流放電(dian)(dian)棒,就(jiu)是(shi)為(wei)了(le)配(pei)電(dian)(dian)系統(tong)及電(dian)(dian)力用戶在現(xian)場檢測各(ge)種高(gao)壓(ya)(ya)電(dian)(dian)器(qi)設備的(de)絕緣(yuan)性(xing)能時,確(que)保人身安全的(de)一種產(chan)品。
(二)FDB型220KV放電棒配置:
銅(tong)線規格(ge):35mm2
銅線長度:6m
接地端(duan):接地夾
接(jie)地(di)端材(cai)質:鋁
(三)FDB型220KV放電棒的工作原理
在進行(xing)沖擊(ji)和直流高壓(ya)設備(bei)以及較大電(dian)(dian)容的(de)試(shi)品試(shi)驗(yan)時(shi),由于試(shi)品在試(shi)驗(yan)線(xian)路中(zhong)為容性負(fu)載,當斷開試(shi)驗(yan)線(xian)路時(shi),試(shi)品上將(jiang)(jiang)有殘余電(dian)(dian)荷(he)存在,形成一個高電(dian)(dian)位。將(jiang)(jiang)會發(fa)生(sheng)(sheng)暫態電(dian)(dian)流電(dian)(dian)擊(ji)而(er)造成人身事故,為了防(fang)止這種現象發(fa)生(sheng)(sheng),試(shi)驗(yan)人員在改(gai)核(he)核(he)線(xian)時(shi),可(ke)用我廠生(sheng)(sheng)產的(de)FDB型高壓(ya)直流放電(dian)(dian)棒在試(shi)品,使(shi)其殘余電(dian)(dian)荷(he)接地在接觸(chu)試(shi)品,為使(shi)放電(dian)(dian)更安全(quan),放電(dian)(dian)棒內還加(jia)裝了限流電(dian)(dian)阻。
(四)的使用方法
將便攜式伸縮新型放電棒伸縮部分全部拉出。然后再將配置好的接地線插頭插入放電棒的頭端部位的插孔內,將地線的另一端與大地連接,放電完畢后,既直流發生器的(de)控(kong)制箱的(de)升壓(ya)璇鈕回(hui)到(dao)零位上,此時(shi)可觀(guan)察控(kong)制箱上的(de)電(dian)(dian)(dian)(dian)壓(ya)表的(de)電(dian)(dian)(dian)(dian)壓(ya)降到(dao)15KV~20KV左(zuo)右,方可放(fang)(fang)電(dian)(dian)(dian)(dian)。放(fang)(fang)電(dian)(dian)(dian)(dian)過程中應先用(yong)放(fang)(fang)電(dian)(dian)(dian)(dian)棒的(de)前端(duan)的(de)金屬尖頭,慢(man)慢(man)的(de)去靠(kao)近(jin)已斷開試驗電(dian)(dian)(dian)(dian)源的(de)試品(pin)。此時(shi)放(fang)(fang)電(dian)(dian)(dian)(dian)棒釋放(fang)(fang)電(dian)(dian)(dian)(dian)能是(shi)經過放(fang)(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)阻進行對地放(fang)(fang)電(dian)(dian)(dian)(dian)。然后再用(yong)放(fang)(fang)電(dian)(dian)(dian)(dian)棒上的(de)鉤子去鉤住試品(pin),進行第二次防電(dian)(dian)(dian)(dian)。
(五(wu))放電(dian)棒的(de)使(shi)用注意事(shi)項
1、放(fang)電前(qian)應先檢查放(fang)電棒接地端后與(yu)接地線連接是否(fou)牢靠(kao)。
2.對(dui)幾(ji)公里以上的(de)高壓電(dian)(dian)纜試驗(yan)結束后(hou),放電(dian)(dian)時間一般(ban)很(hen)長,且(qie)需(xu)多次反復放電(dian)(dian)。電(dian)(dian)阻容量要很(hen)大,需(xu)訂購(gou)大容量的(de)放電(dian)(dian)棒。
3.嚴禁未拉開(kai)試(shi)驗電源用放電棒對試(shi)品進行(xing)放電。
4.嚴禁用(yong)腳(jiao)踩及重(zhong)物擠(ji)壓放電棒,嚴禁折彎,折斷放電棒。
5.嚴禁將放電棒(bang)受潮(chao),影響絕緣強度,應放在干燥的地方。
6.放電(dian)時工作人員(yuan)不可接觸地線
