技術參數：

1．輸入(ru)電(dian)阻100M

2．測試電壓：DC0-30KV

3．電壓精(jing)度：1.0%

4． 試驗(yan)(yan)方法： 1 試驗(yan)(yan)標(biao)準(zhun)發(fa)電(dian)機定子線圈端部絕緣判斷標(biao)準(zhun)，是(shi)加(jia)2 倍(bei)的(de)額定電(dian)壓，漏泄(xie)電(dian)流不大于1微安

5． 試驗儀器直流高壓發生裝置(zhi)

6． 測(ce)試原理將(jiang)直流電(dian)壓(ya)加(jia)在定(ding)子線棒正(zheng)常時由于線棒絕(jue)緣(yuan)的體積(ji)電(dian)阻Ρρ 遠遠大于表面電(dian)阻ρσ , 對(dui)地(di)(di)電(dian)壓(ya)很低(di)， 若某一線棒絕(jue)緣(yuan)存在缺(que)陷,它的電(dian)壓(ya)分布將(jiang)發生明顯的變(bian)化,絕(jue)緣(yuan)存在缺(que)陷時, Ρρ 減小,絕(jue)緣(yuan)壓(ya)降也降低(di),致使缺(que)陷部(bu)位對(dui)地(di)(di)電(dian)壓(ya)增高。

7． 測試方法將繞(rao)組(zu)三相引出線用導線短路連接，直流高壓(ya)發生(sheng)器加2倍(bei)電(dian)(dian)壓(ya)，用發電(dian)(dian)機(ji)電(dian)(dian)位外(wai)移(yi)試驗儀測試電(dian)(dian)壓(ya)和電(dian)(dian)流 5．發電(dian)(dian)機(ji)電(dian)(dian)位外(wai)移(yi)試驗儀接線圖

8．尾(wei)棒的地線一定與高壓發生裝置(zhi)的地線接在一起。

注意事項：

1、錫箔紙纏包端部時，一定(ding)要包裹緊(jin)密，否則錫箔紙和絕緣表(biao)面會構成電容，

測(ce)量(liang)桿接(jie)觸時會有(you)較大的放電電流,造成(cheng)誤判斷。

2、端部(bu)包(bao)裹(guo)時好分為線棒側(ce)和引水(shui)管(guan)側(ce)，間隔(ge)大(da)于3厘米(mi)，電位高時便于檢查是(shi)一(yi)側(ce)的問題，其實*主要的點是(shi)根(gen)部(bu)和錐部(bu)，中間部(bu)位測量(liang)意(yi)義不大(da)。

3、測量(liang)桿串接的微安表(biao)好用數字式微安表(biao)，即便于讀(du)數又(you)可(ke)電流大時保護

表記。

4、端部接頭因(yin)為在在機殼下部，不易測量，提前用引(yin)線引(yin)出。

5、重要(yao)的是(shi)記(ji)正確異常槽(cao)號，避免張(zhang)冠(guan)李戴，切記(ji)切記(ji)！

6、發電機不(bu)通(tong)水(shui)(shui)的(de)情(qing)況下進行試驗(yan)，要求先將定子冷卻水(shui)(shui)吹凈。
