漏電起痕試驗儀采用矩形鉑電(dian)(dian)(dian)(dian)極(ji)(ji)，兩(liang)極(ji)(ji)對試(shi)(shi)樣的作(zuo)用力分別為1.0N±0.05N。施加電(dian)(dian)(dian)(dian)壓(ya)在100～600V(48～60Hz)之間(jian)(jian)可(ke)調，短(duan)(duan)路電(dian)(dian)(dian)(dian)流(liu)在1.0±0.1A時(shi)(shi)，電(dian)(dian)(dian)(dian)壓(ya)下降應不超過10%，當(dang)試(shi)(shi)驗(yan)回路中，短(duan)(duan)路漏電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)等于或大于0. 時(shi)(shi)，時(shi)(shi)間(jian)(jian)維(wei)持2秒(miao)鐘，繼電(dian)(dian)(dian)(dian)器動作(zuo)，切斷電(dian)(dian)(dian)(dian)流(liu)，指示(shi)試(shi)(shi)件(jian)不合(he)格(ge)。滴(di)液裝置時(shi)(shi)間(jian)(jian)常數可(ke)調，控制(zhi)滴(di)液量大小(xiao)44～50滴(di)/cm3和(he)滴(di)液時(shi)(shi)間(jian)(jian)間(jian)(jian)隔(ge)30±5秒(miao)。符合(he)GB/T4207-2012固體絕緣(yuan)材料耐(nai)電(dian)(dian)(dian)(dian)痕化指數和(he)相比電(dian)(dian)(dian)(dian)痕化指數的測(ce)定方(fang)法、GB/T3048.7-2007電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)性能(neng)試(shi)(shi)驗(yan)方(fang)法第(di)7部分：耐(nai)電(dian)(dian)(dian)(dian)痕試(shi)(shi)驗(yan)等試(shi)(shi)驗(yan)標準

漏電起痕試驗儀在操作過程中要注意的事項：

1、漏電(dian)起(qi)痕試驗儀(yi)在操作過程中，人員應該注意個人防護，避免漏電(dian)受傷或被溶液沾染到口、眼部位造(zao)成傷害

2、輸(shu)入電源AC220±2%。

3、排(pai)氣管應通出(chu)窗外(wai)。

4、在對(dui)樣品進行(xing)時,請勿(wu)打(da)開(kai)倉門,待試驗(yan)(yan)完(wan)之后(hou)(hou)或當(dang)實(shi)驗(yan)(yan)失效(xiao)產(chan)生火(huo)煙時，先打(da)開(kai)風扇排除煙霧后(hou)(hou)，再打(da)開(kai)倉門進行(xing)作(zuo)業。

5、實驗前(qian)須確認設備是(shi)否在計量有效(xiao)期內，如超期則(ze)不能進行實驗

6、電源應(ying)用有(you)地線的(de)三極插座，保證接地可(ke)靠
