工頻耐壓經過多次(ci)實(shi)驗發(fa)現經過多次(ci)實(shi)驗發(fa)現運作還要注意問(wen)題

1）檢測成員應開展職責分工，確立(li)充分間技巧。并有正規人撫養(yang)現場(chang)安全可靠(kao)及(ji)分析(xi)試品的狀態。

2）被試(shi)品應當先(xian)環境衛生整(zheng)治乾凈，并太干，盡量損傷被試(shi)品和疲(pi)勞試(shi)驗(yan)分享的測量誤差。

3）來說大中(zhong)型做實驗(yan)的時候，大部分都時先對其進行空升(sheng)做實驗(yan)的時候。即(ji)不接試品時升(sheng)壓(ya)至做實驗(yan)的時候電阻值，校對很多(duo)表計，進行調節球齒隙。

4）升壓進程未(wei)能太快，并有必要預防猛(meng)然(ran)間(jian)施壓。舉(ju)例調壓器(qi)沒有在(zai)(zai)零位時(shi)猛(meng)然(ran)間(jian)送電(dian)。也未(wei)能猛(meng)然(ran)間(jian)切段電(dian)壓，似的應在(zai)(zai)調壓器(qi)下降零位時(shi)拉(la)閘。

5）當的電壓降(jiang)降(jiang)上升測試(shi)(shi)的電壓降(jiang)降(jiang)時，著(zhu)手倒(dao)計時鐘，到1min后(hou)，更快穩(wen)壓到1/3測試(shi)(shi)的電壓降(jiang)降(jiang)下述(shu)時，就能已經拉開電壓。

一(yi)、企業產品簡析

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。
