絕緣材料的漏電起痕試驗儀的工作原理：

由各個調(diao)(diao)節(jie)(jie)裝置分別調(diao)(diao)節(jie)(jie)各器(qi)(qi)件(jian)(jian)的(de)(de)(de)功能。 由自偶調(diao)(diao)壓(ya)(ya)(ya)器(qi)(qi)連接升壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器(qi)(qi)，實現電(dian)(dian)(dian)壓(ya)(ya)(ya)調(diao)(diao)節(jie)(jie)，使(shi)次級輸出為0- 600V連續可(ke)調(diao)(diao)的(de)(de)(de)交流(liu)正弦波電(dian)(dian)(dian)壓(ya)(ya)(ya)，以滿足試驗所需的(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)值；通(tong)過調(diao)(diao)節(jie)(jie)電(dian)(dian)(dian)壓(ya)(ya)(ya)粗調(diao)(diao)開關和電(dian)(dian)(dian)壓(ya)(ya)(ya)細調(diao)(diao)、電(dian)(dian)(dian)流(liu)調(diao)(diao)節(jie)(jie)電(dian)(dian)(dian)位器(qi)(qi)使(shi)輸出電(dian)(dian)(dian)流(liu)改變(bian)，使(shi)不同的(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)下短路電(dian)(dian)(dian)流(liu)均整(zheng)定為1.0±0.1A；松(song)開電(dian)(dian)(dian)極桿的(de)(de)(de)緊(jin)固螺(luo)釘，可(ke)調(diao)(diao)節(jie)(jie)兩(liang)電(dian)(dian)(dian)極桿的(de)(de)(de)伸(shen)縮,改變(bian)兩(liang)電(dian)(dian)(dian)極的(de)(de)(de)間距；調(diao)(diao)節(jie)(jie)電(dian)(dian)(dian)極桿的(de)(de)(de)配重件(jian)(jian)的(de)(de)(de)位置，可(ke)調(diao)(diao)節(jie)(jie)兩(liang)個電(dian)(dian)(dian)極對被測件(jian)(jian)的(de)(de)(de)壓(ya)(ya)(ya)力；調(diao)(diao)節(jie)(jie)滴液(ye)器(qi)(qi)的(de)(de)(de)調(diao)(diao)節(jie)(jie)閥(fa)(fa)并配合電(dian)(dian)(dian)磁閥(fa)(fa)的(de)(de)(de)時間繼(ji)電(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)時間(0.01～1S)，既可(ke)調(diao)(diao)節(jie)(jie)液(ye)滴大小
