高壓(ya)(ya)放電(dian)(dian)(dian)棒是利(li)用新型(xing)絕緣材(cai)料加工而(er)成。它(ta)具有能拉長(chang)，又(you)能收縮(suo)的特點。便(bian)(bian)攜式伸(shen)(shen)縮(suo)型(xing)高壓(ya)(ya)放電(dian)(dian)(dian)棒便(bian)(bian)于(yu)(yu)在室外各(ge)項高電(dian)(dian)(dian)壓(ya)(ya)試(shi)驗中使用，特別在做直(zhi)流耐壓(ya)(ya)試(shi)驗后，對(dui)試(shi)品上(shang)積(ji)累的電(dian)(dian)(dian)荷，進行對(dui)地放電(dian)(dian)(dian)，確保人身安(an)全。伸(shen)(shen)縮(suo)型(xing)高壓(ya)(ya)放電(dian)(dian)(dian)棒便(bian)(bian)于(yu)(yu)攜帶，方便(bian)(bian)、靈(ling)活，具有體積(ji)小、重量輕(qing)、安(an)全。

   放電棒使用方法

1、將便攜式伸縮型高壓放電(dian)棒伸縮部(bu)分全部(bu)拉出。 　　

2、把配制好的接地(di)(di)線插頭(tou)插入放電棒的頭(tou)端(duan)部位的插孔內，將地(di)(di)線的另一(yi)端(duan)與大地(di)(di)連(lian)接，接地(di)(di)要可靠。 　　

3、放(fang)電(dian)時應在試(shi)驗完畢后(hou)，即直流發生(sheng)器的(de)控制箱的(de)升壓(ya)旋鈕回到零(ling)位上(shang)，此時可(ke)觀察直流高(gao)壓(ya)發生(sheng)器控制箱上(shang)的(de)電(dian)壓(ya)表(biao)的(de)電(dian)壓(ya)下降到15kV～20kV左右，方可(ke)放(fang)電(dian)。 　　

4、放(fang)(fang)電(dian)時(shi)應先用(yong)放(fang)(fang)電(dian)棒(bang)的前(qian)端的金屬尖(jian)頭(tou)，慢(man)慢(man)的去靠近已斷開試(shi)(shi)驗電(dian)源的試(shi)(shi)品。此時(shi)放(fang)(fang)電(dian)棒(bang)釋放(fang)(fang)電(dian)能是(shi)經過一放(fang)(fang)電(dian)電(dian)阻進行對地放(fang)(fang)電(dian)。然(ran)后再用(yong)放(fang)(fang)電(dian)棒(bang)上接(jie)地線上的鉤子去鉤住(zhu)試(shi)(shi)品，進行第二(er)次(ci)直接(jie)對地放(fang)(fang)電(dian)。

放電棒注意(yi)事項

1、對大電(dian)(dian)容試(shi)品放(fang)(fang)電(dian)(dian)時，須在試(shi)驗完畢后(hou)，斷開試(shi)驗電(dian)(dian)源(yuan)后(hou)，應該(gai)等待一段時間(jian)后(hou)，使試(shi)品上的(de)電(dian)(dian)荷通(tong)過倍壓(ya)(ya)(ya)筒及試(shi)品本身對地自放(fang)(fang)電(dian)(dian)。此(ci)時可(ke)觀(guan)察控制箱(xiang)上的(de)電(dian)(dian)壓(ya)(ya)(ya)表(biao)電(dian)(dian)壓(ya)(ya)(ya)數在逐(zhu)步下降跌落，當電(dian)(dian)壓(ya)(ya)(ya)表(biao)電(dian)(dian)壓(ya)(ya)(ya)下降到較(jiao)低的(de)電(dian)(dian)壓(ya)(ya)(ya)，一般在5kV～15kV左右(you)，方可(ke)用放(fang)(fang)電(dian)(dian)棒去逐(zhu)步移向試(shi)品附近(jin)。先通(tong)過間(jian)隙空氣(qi)游(you)離放(fang)(fang)電(dian)(dian)，此(ci)時可(ke)聽到嘶嘶的(de)聲(sheng)音(yin)，當無聲(sheng)音(yin)后(hou)，用放(fang)(fang)電(dian)(dian)棒*去碰(peng)試(shi)品，zui后(hou)將試(shi)品直接接地放(fang)(fang)電(dian)(dian)。 　　

2、大電(dian)容(rong)試(shi)品積(ji)累電(dian)荷(he)的(de)大小與試(shi)品電(dian)容(rong)的(de)大小和施(shi)加電(dian)壓的(de)高低與時間的(de)長短(duan)成正比。 　　

3、對幾(ji)公里以上(shang)的高(gao)壓電(dian)纜試驗結束后，放(fang)電(dian)時間(jian)一般都要很(hen)長，且需多次(ci)反(fan)復放(fang)電(dian)。電(dian)阻(zu)容量(liang)要很(hen)大，需訂購大容量(liang)的放(fang)電(dian)棒。 　　

4、嚴禁未拉開試驗電源用(yong)放(fang)電棒對試品進(jin)行放(fang)電。 　　

5、嚴(yan)禁用腳(jiao)踩及重(zhong)物(wu)擠壓放(fang)電棒(bang)，嚴(yan)禁折彎、折斷放(fang)電棒(bang)。 　　

6、嚴禁將放電棒受(shou)潮，影響絕緣強度，應放在(zai)干燥的地方。
