便攜式高壓發生裝置注意事項：

1、試(shi)驗前檢查測試(shi)品(pin)(pin)、直流(liu)高(gao)壓發生(sheng)器、倍壓筒、放(fang)電棒、接地線(xian)(xian)、試(shi)品(pin)(pin)聯接線(xian)(xian)是(shi)否接好，檢查接地線(xian)(xian)是(shi)否連接無誤。

2、高壓(ya)輸出接線必須牢固，試(shi)驗(yan)時防止高壓(ya)引線脫落，對地直接放電損壞儀器。

3、高壓試驗時周圍物體(ti)及人員必須(xu)保持足夠(gou)的(de)安(an)全距(ju)離

3、在工(gong)作電源進入試(shi)驗(yan)器前加裝(zhuang)兩個明顯斷開點，更換被試(shi)品和(he)接線(xian)時應先將工(gong)作電源斷開點明顯斷開；

4、在電纜耐壓(ya)試驗過程中(zhong)，升壓(ya)過程應(ying)勻速緩慢(man)，降壓(ya)過程也(ye)應(ying)勻速緩慢(man)，同時應(ying)在高壓(ya)輸出端(duan)加上(shang)保護水阻。否則(ze)，反(fan)電壓(ya)易損壞(huai)儀(yi)器(qi)。

5、對(dui)大容性(xing)被(bei)試(shi)品(pin)(pin)的放(fang)電(dian)(dian)(dian)(dian)(dian)應(ying)經(jing)100Ω/V放(fang)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)阻棒對(dui)被(bei)試(shi)品(pin)(pin)放(fang)電(dian)(dian)(dian)(dian)(dian)，放(fang)電(dian)(dian)(dian)(dian)(dian)時不能將(jiang)放(fang)電(dian)(dian)(dian)(dian)(dian)棒立即接(jie)(jie)觸試(shi)品(pin)(pin)，應(ying)先將(jiang)放(fang)電(dian)(dian)(dian)(dian)(dian)棒逐漸(jian)接(jie)(jie)近試(shi)品(pin)(pin)，至一定距離空(kong)氣間隙開(kai)始(shi)游離放(fang)電(dian)(dian)(dian)(dian)(dian)有嘶嘶聲(sheng)，當無聲(sheng)音時可用放(fang)電(dian)(dian)(dian)(dian)(dian)棒接(jie)(jie)地(di)端放(fang)電(dian)(dian)(dian)(dian)(dian)，后(hou)直接(jie)(jie)接(jie)(jie)上(shang)地(di)線放(fang)電(dian)(dian)(dian)(dian)(dian)；
