水內冷發電機組試驗裝置特點

根據“低壓(ya)屏蔽(bi)法”原理研制的，實(shi)現(xian)了(le)在(zai)通水情況下對(dui)水內冷發電機進行直(zhi)流(liu)耐壓(ya)和直(zhi)流(liu)泄漏電流(liu)的試(shi)驗。*克(ke)服(fu)了(le)吹水時間長，底部(bu)積水難吹干，易引起線圈內拉弧等(deng)難題。

整套裝置接線簡單，極化補(bu)償電壓由(you)機箱直接輸出。采用電子 控制與調諧(xie)，操作(zuo)方(fang)便(bian)；電(dian)壓(ya)、電(dian)流(liu)均在面(mian)板計上一次讀(du)數無需換算。一分鐘定時及提示功(gong)能，按試驗規程要求設定。機內過壓(ya)過流(liu)保護功(gong)能完善，外(wai)附(fu)氧化鋅過壓(ya)保護裝置更確保發電(dian)機安全，*。便(bian)攜(xie)式(shi)結(jie)構，特別適合(he)現(xian)場試驗。
