工頻耐沖擊應力測試運營關注要點(dian)

1）測(ce)試(shi)職(zhi)工應寫好要(yao)明確分工，要(yao)明確完美間技術(shu)。并有正(zheng)規(gui)人監護(hu)人現廠安(an)全的及仔細觀察試(shi)品感覺。

2）被試品前應清掃工清潔，并干澀，免得損毀被試品和應力(li)測試創造的(de)差值。

3）針對于專業(ye)校正(zheng)，基本(ben)都應從(cong)去空升校正(zheng)。即不接試品時(shi)升壓至(zhi)校正(zheng)的(de)電壓，校對所有表計，調(diao)節球(qiu)孔徑(jing)。

4）升壓車速無法太快，并需避免沒(mei)預(yu)兆(zhao)加壓力(li)。列(lie)如 調(diao)壓器(qi)不是在(zai)零位(wei)時(shi)沒(mei)預(yu)兆(zhao)送電。也無法沒(mei)預(yu)兆(zhao)掐(qia)斷(duan)開(kai)關電源，一樣 應在(zai)調(diao)壓器(qi)降低(di)零位(wei)時(shi)拉(la)閘。

5）當電(dian)(dian)(dian)流(liu)(liu)工作(zuo)電(dian)(dian)(dian)壓(ya)降(jiang)(jiang)升(sheng)為實驗電(dian)(dian)(dian)流(liu)(liu)工作(zuo)電(dian)(dian)(dian)壓(ya)降(jiang)(jiang)時，逐漸開始倒計時，到1min后，飛速降(jiang)(jiang)血壓(ya)到1/3實驗電(dian)(dian)(dian)流(liu)(liu)工作(zuo)電(dian)(dian)(dian)壓(ya)降(jiang)(jiang)接下(xia)來(lai)時，就能夠保持(chi)開關電(dian)(dian)(dian)源。

6）在升壓或(huo)耐沖擊(ji)實驗歷程中，如感覺(jue)下(xia)面(mian)不(bu)(bu)對常實際情況時，應會穩壓，關閉(bi)交流電(dian)源。立即停止實驗并查證原因：①的電(dian)壓表指南搖動很多；②感覺(jue)接地燒化或(huo)冒氣；③被試品內(nei)有不(bu)(bu)對常的生音(yin)。

7）耐沖擊試驗報告(gao)前后的應(ying)衡量絕(jue)緣(yuan)性(xing)層內阻，審核(he)絕(jue)緣(yuan)性(xing)層的情況。

一、產品概況

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。

為(wei)分離式式裝備。即(ji)成(cheng)倍(bei)高發期生器和成(cheng)倍(bei)頻(pin)掌(zhang)握(wo)保養控制系統，并(bing)現有濾水(shui)保養，電(dian)流值(zhi)表、成(cheng)倍(bei)頻(pin)輸送、電(dian)壓值(zhi)表，以實施把握(wo)和于適用(yong)，其(qi)掌(zhang)握(wo)保養控制系統后(hou)蓋板上進(jin)行連接(jie)線柱與(yu)主機箱進(jin)行連接(jie)辦法一下圖(tu)右圖(tu)：

（按插頭接(jie)(jie)線(xian)處圖將(jiang)本(ben)安(an)全裝置(zhi)組(zu)網(wang)方式(shi)中，注重機(ji)械跨(kua)接(jie)(jie)）

上班電源模塊進入	3倍頻三相電發送	單相電150HZ	220V150HZ	等電位連接
二相220V	380V	輸出	模擬輸出

按以(yi)下幾點過程對(dui)其進(jin)行使用：

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、假如耐(nai)(nai)壓耐(nai)(nai)壓試(shi)驗(yan)(yan)時候中(zhong)，被試(shi)品現身匝間(jian)、層間(jian)或段間(jian)、兩(liang)色相(xiang)間(jian)接地穿透后(hou)果(guo)，則保(bao)持電路開關中(zhong)耐(nai)(nai)壓耐(nai)(nai)壓試(shi)驗(yan)(yan)交(jiao)流電增(zeng)高，按鈕開關設備可實(shi)時沒電，沒電。

５、疲勞試驗結(jie)束后，將(jiang)調壓器追(zhui)回(hui)零(ling)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％。
