工(gong)頻抗壓試驗報告運(yun)行(xing)需(xu)要注意法定程序

1）實(shi)驗設計(ji)者應完成明確(que)責(ze)任(ren)分工，明確(que)責(ze)任(ren)彼此間做法。并有有能人(ren)重(zhong)癥監護現象(xiang)安(an)全性高及關察試(shi)品(pin)的狀態。

2）被試(shi)品前先掃除(chu)整潔，并干澡，為了避免破損被試(shi)品和沖擊試(shi)驗引來的測量(liang)誤(wu)差。

3）來說中小型經(jing)過(guo)(guo)多(duo)次實驗發現(xian)，一樣 都前應去空升經(jing)過(guo)(guo)多(duo)次實驗發現(xian)。即不接試品(pin)時升壓至經(jing)過(guo)(guo)多(duo)次實驗發現(xian)電流(liu)值，校(xiao)對(dui)各式表計，調控(kong)球油隙。

4）升(sheng)壓(ya)轉速不太快(kuai)，并須要放到沒(mei)(mei)預兆(zhao)充壓(ya)。隨后(hou)調壓(ya)器沒(mei)(mei)在零(ling)位時沒(mei)(mei)預兆(zhao)重(zhong)合(he)閘。也是(shi)沒(mei)(mei)預兆(zhao)割(ge)斷電源適配(pei)器，一般的應在調壓(ya)器降(jiang)為零(ling)位時拉閘。

5）當相輸(shu)出(chu)功(gong)率(lv)升為檢測相輸(shu)出(chu)功(gong)率(lv)時，逐(zhu)漸開(kai)始倒計時，到(dao)1min后(hou)，快減壓到(dao)1/3檢測相輸(shu)出(chu)功(gong)率(lv)下例時，才保(bao)持電源模塊。

6）在升壓(ya)或擊穿(chuan)直(zhi)流電(dian)壓(ya)耐壓(ya)裝(zhuang)置流程中，如察覺(jue)到列舉一(yi)高(gao)一(yi)低(di)常實際(ji)情況時，應及時減壓(ya)，打斷電(dian)源適(shi)配器。進行(xing)耐壓(ya)裝(zhuang)置并追查主(zhu)觀原因：①直(zhi)流電(dian)壓(ya)表游標搖(yao)晃相當大；②察覺(jue)到隔(ge)絕糊味或冒(mao)火(huo)；③被試品內有一(yi)高(gao)一(yi)低(di)常的(de)聲(sheng)響。

7）耐壓性試(shi)驗報告先后應測定接地(di)電阻器，檢查報告接地(di)原(yuan)因(yin)。

做(zuo)(zuo)實(shi)驗的時候電(dian)抗器在做(zuo)(zuo)被試品的直(zhi)流電(dian)源抗壓(ya)或暴露做(zuo)(zuo)實(shi)驗的時候時連接線操作過程圖所示(shi)6。

注：此檢測時要多抽出(chu)出(chu)現(xian)短(duan)路桿(gan)“D”，圖6里(li)面示。

一、食(shi)品簡(jian)析

變壓器和互感器的感應耐壓試驗是保證變壓器質量符合國家標準的一項重要試驗。變壓器繞組的匝間、層間、段間及相間絕緣的縱絕緣感應耐壓試驗，則是變壓器絕緣試驗中的重要項目。基于縱絕緣試驗中的特殊性，需要通過施加倍頻電源裝置，以提高繞組間絕緣的試驗電壓，從而達到耐壓試驗的目的。
是為滿足上述要求而設計制造，經過廣大用戶使用證明：其操作簡單、性能可靠、能較好地滿足變壓器、互感器感應耐壓試驗的需要。

按下面(mian)具體步驟做出操作方法：

１、接通電源，合上空氣開關，則控制裝置綠色指示燈亮。
２、將調壓器回零，啟動紅色按鈕，則三倍頻發生器通電運行，調壓器等待升壓。
３、將調壓器調壓至試驗所需電壓值且嚴密監視控制裝置中的電流和電壓值，并作好詳細記錄。

４、比如(ru)在實驗檢(jian)測時中，被試品出現了匝間(jian)、層間(jian)或段間(jian)、兩色相間(jian)隔熱(re)熱(re)擊穿跡象，則把握雙回路中實驗檢(jian)測功率(lv)大(da)，繼電囂可盡快跳閘推不上去，跳電。

５、試驗(yan)檢測完，將調壓器退還零位。

五、外接補償問題：
對容性負載如高壓試驗變壓器、電容式電壓互感器可不外接補償，或外接感性補償。對感性負載，一般外接容性補償，其補償值為感性負載容量的50％。
