產品說明:
直流高壓放電棒/伸縮型高壓放電棒又名高壓放電棒是我們公司利用新型絕緣材料加工而成。它具有能拉長,又能收縮的特點。便攜式伸縮型高壓放電棒便于在室外各項高電壓試驗中使用,特別在做直流耐壓試驗后,對試品上積累的電荷,進行對地放電,確保人身安全。伸縮型高壓放電棒便于攜帶,方便、靈活,具有體積小、重量輕、安全。也叫“便攜式高壓放電棒"。 試驗變壓器直流高壓放電棒,直流高壓發生器放電棒

產品使(shi)用:
1、將便攜式(shi)伸(shen)縮型高(gao)壓(ya)放電棒伸(shen)縮部(bu)分全(quan)部(bu)拉出。
2、把配制好(hao)的接(jie)地(di)線(xian)插頭插入放電棒的頭端(duan)部(bu)位的插孔內,將(jiang)地(di)線(xian)的另一端(duan)與大地(di)連接(jie),接(jie)地(di)要可靠。
3、放電(dian)時應在試驗完畢后,即直(zhi)流(liu)發生器(qi)的(de)控制箱(xiang)的(de)升壓(ya)旋鈕回到零位上(shang)(shang),此時可(ke)觀察直(zhi)流(liu)高壓(ya)發生器(qi)控制箱(xiang)上(shang)(shang)的(de)電(dian)壓(ya)表的(de)電(dian)壓(ya)下(xia)降到15kV~20kV左右,方可(ke)放電(dian)。
4、放(fang)電(dian)(dian)時應先(xian)用放(fang)電(dian)(dian)棒的(de)(de)前(qian)端的(de)(de)金屬尖頭,慢慢的(de)(de)去靠近已(yi)斷開試驗電(dian)(dian)源的(de)(de)試品(pin)。此(ci)時放(fang)電(dian)(dian)棒釋放(fang)電(dian)(dian)能是(shi)經(jing)過一(yi)放(fang)電(dian)(dian)電(dian)(dian)阻進(jin)行對(dui)地放(fang)電(dian)(dian)。然后再(zai)用放(fang)電(dian)(dian)棒上(shang)(shang)接地線上(shang)(shang)的(de)(de)鉤子去鉤住試品(pin),進(jin)行第(di)二次直接對(dui)地放(fang)電(dian)(dian)。
注(zhu)意事項(xiang):
1、對大電(dian)(dian)(dian)(dian)容試(shi)(shi)(shi)品(pin)(pin)放(fang)電(dian)(dian)(dian)(dian)時(shi),須在試(shi)(shi)(shi)驗(yan)完(wan)畢(bi)后(hou),斷開(kai)試(shi)(shi)(shi)驗(yan)電(dian)(dian)(dian)(dian)源后(hou),應該等待一段(duan)時(shi)間(jian)后(hou),使試(shi)(shi)(shi)品(pin)(pin)上(shang)(shang)的(de)電(dian)(dian)(dian)(dian)荷通過(guo)倍(bei)壓(ya)(ya)筒及試(shi)(shi)(shi)品(pin)(pin)本身對地(di)自放(fang)電(dian)(dian)(dian)(dian)。此時(shi)可(ke)觀察控(kong)制箱(xiang)上(shang)(shang)的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)表電(dian)(dian)(dian)(dian)壓(ya)(ya)數在逐步(bu)下(xia)降跌落(luo),當(dang)電(dian)(dian)(dian)(dian)壓(ya)(ya)表電(dian)(dian)(dian)(dian)壓(ya)(ya)下(xia)降到較低的(de)電(dian)(dian)(dian)(dian)壓(ya)(ya),一般在5kV~15kV左右,方(fang)可(ke)用放(fang)電(dian)(dian)(dian)(dian)棒去(qu)逐步(bu)移(yi)向試(shi)(shi)(shi)品(pin)(pin)附(fu)近。先通過(guo)間(jian)隙空(kong)氣游離(li)放(fang)電(dian)(dian)(dian)(dian),此時(shi)可(ke)聽到嘶嘶的(de)聲音(yin),當(dang)無聲音(yin)后(hou),用放(fang)電(dian)(dian)(dian)(dian)棒去(qu)碰(peng)試(shi)(shi)(shi)品(pin)(pin),zui后(hou)將試(shi)(shi)(shi)品(pin)(pin)直接接地(di)放(fang)電(dian)(dian)(dian)(dian)。
2、大電容試(shi)品積累電荷的(de)大小與試(shi)品電容的(de)大小和施加(jia)電壓的(de)高低與時間的(de)長短成正比。
3、對幾公里以上的高(gao)壓電(dian)(dian)纜試驗結束后,放(fang)電(dian)(dian)時間一般(ban)都(dou)要(yao)很長,且需(xu)多次反復放(fang)電(dian)(dian)。電(dian)(dian)阻(zu)容量要(yao)很大,需(xu)訂購大容量的放(fang)電(dian)(dian)棒。
4、嚴禁未拉(la)開試(shi)(shi)驗電(dian)源用放電(dian)棒(bang)對試(shi)(shi)品進行放電(dian)。
5、嚴禁(jin)用腳踩及(ji)重物擠(ji)壓(ya)放(fang)電棒,嚴禁(jin)折彎、折斷放(fang)電棒。
6、嚴(yan)禁將放電棒受潮,影響絕緣強度,應放在干(gan)燥(zao)的地方。
