工(gong)頻耐壓實驗設(she)計實驗設(she)計運作需要注(zhu)意(yi)項目

1）試驗報告(gao)工人(ren)應準備(bei)好安(an)排，清楚相互間間的(de)方(fang)法。并有專門針(zhen)對人(ren)撫養實地健康及(ji)觀測試品的(de)狀(zhuang)態(tai)。

2）被試品前(qian)應傳統(tong)清(qing)掃整潔，并低溫干燥，一旦受損(sun)被試品和經(jing)過多(duo)次(ci)實驗發現引來的測(ce)量誤差。

3）對(dui)於玄幻測試(shi)，尋常都應(ying)從開始空(kong)升測試(shi)。即不接試(shi)品時升壓(ya)至測試(shi)端(duan)電壓(ya)，校對(dui)不同(tong)的表計，調準球空(kong)隙。

4）升壓運(yun)行速度不(bu)能夠太快，并應該杜絕忽然(ran)施壓。舉個例子(zi)調(diao)壓器(qi)不(bu)是(shi)零位(wei)時(shi)(shi)忽然(ran)分閘(zha)。并不(bu)能夠忽然(ran)打斷外接電源，一(yi)半應在調(diao)壓器(qi)減至零位(wei)時(shi)(shi)拉閘(zha)。

5）當電(dian)阻(zu)(zu)降為可靠性試(shi)(shi)驗裝置(zhi)電(dian)阻(zu)(zu)時，著手手表，到1min后，較快降血(xue)壓到1/3可靠性試(shi)(shi)驗裝置(zhi)電(dian)阻(zu)(zu)有以(yi)下時，就(jiu)能夠拉到外接電(dian)源。

6）在(zai)升壓或耐壓做實驗(yan)(yan)的時(shi)候(hou)(hou)做實驗(yan)(yan)的時(shi)候(hou)(hou)階段中，如看到(dao)以下(xia)不(bu)穩(wen)常事(shi)情時(shi)，應會減壓，斷(duan)掉電(dian)阻(zu)。暫停做實驗(yan)(yan)的時(shi)候(hou)(hou)并(bing)查實主要原因：①電(dian)阻(zu)表指南(nan)扭動好(hao)大；②看到(dao)隔絕燒化或冒火；③被試品(pin)內(nei)有不(bu)穩(wen)常的聲。

一、軟(ruan)件(jian)綜述

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。
