工頻耐壓(ya)性實(shi)驗方(fang)法注意力(li)議題

1）測(ce)試工人應做到任務分(fen)配，明確化互不間步(bu)驟(zou)。并有特定人看護實地很(hen)安全及觀查試品感覺。

2）被(bei)試品需要先清掃垃圾不臟，并烘干，否則傷(shang)害被(bei)試品和(he)疲勞試驗(yan)帶給的(de)差值。

3）在中大型(xing)可(ke)靠性現(xian)場(chang)實(shi)驗(yan)，常(chang)見都(dou)前先(xian)完成空(kong)升可(ke)靠性現(xian)場(chang)實(shi)驗(yan)。即不接(jie)試品時升壓至可(ke)靠性現(xian)場(chang)實(shi)驗(yan)相電壓，校對各樣表計，修(xiu)改球(qiu)氣隙。

4）升壓時(shi)速不會(hui)(hui)太快，并有必要以防就負壓。舉例調壓器(qi)未在(zai)零位時(shi)就重合閘。從來不會(hui)(hui)就切割供(gong)電，一樣應在(zai)調壓器(qi)下(xia)降零位時(shi)拉閘。

5）當線電(dian)壓(ya)(ya)值(zhi)值(zhi)上(shang)升到(dao)可靠性(xing)(xing)耐(nai)(nai)壓(ya)(ya)線電(dian)壓(ya)(ya)值(zhi)值(zhi)時，剛開始(shi)記時，到(dao)1min后，快速發展(zhan)穩壓(ya)(ya)到(dao)1/3可靠性(xing)(xing)耐(nai)(nai)壓(ya)(ya)線電(dian)壓(ya)(ya)值(zhi)值(zhi)這時，方可已(yi)經形成了電(dian)源開關。

6）在升壓(ya)或耐壓(ya)性應力測試時候中，如會出現 以下不(bu)當常(chang)(chang)條件時，應會減(jian)壓(ya)，切割電(dian)源適配器。消(xiao)停應力測試并查(cha)清(qing)緣由(you)：①電(dian)流(liu)值(zhi)表表針晃動挺大；②會出現 絕緣層(ceng)燒(shao)化或起煙；③被試品(pin)內有不(bu)當常(chang)(chang)的響聲。

7）耐(nai)沖擊檢測后應在(zai)線測量(liang)隔絕(jue)帶(dai)熱敏電(dian)阻，檢查報(bao)告隔絕(jue)帶(dai)具體情況(kuang)。

丟失耐壓的實操及關注須知

1）沖(chong)擊耐壓試(shi)驗(yan)需要先(xian)查被(bei)試(shi)品什么情況(kuang)(kuang)下停(ting)機，接(jie)地裝置(zhi)發出電，任何事(shi)物地方政府連線(xian)什么情況(kuang)(kuang)下擦水(shui)凈。要謹防將沖(chong)擊耐壓試(shi)驗(yan)交(jiao)流電壓加到夢見過(guo)世的人事(shi)情的內臟器官(guan)進去。

2）接(jie)好經過多次實(shi)驗(yan)發現(xian)系統的(de)接(jie)線(xian)方(fang)法后，應(ying)復查(cha)工(gong)(gong)作相符后才需(xu)加壓。應(ying)十(shi)分要(yao)注(zhu)意查(cha)驗(yan)各類高(gao)壓系統及(ji)引線(xian)與地、與工(gong)(gong)作工(gong)(gong)作人員的(de)平安差距，被試品的(de)機殼是否有穩定一定接(jie)地，要(yao)按平安規章程序中其中規定的(de)內(nei)容使用經過多次實(shi)驗(yan)發現(xian)。

3）這對大(da)電阻量(liang)裝置應慢慢升壓，解決辦法被試品的充電器瞬時電流(liu)損壞微安表(biao)。有需要應該把冷卻水分(fen)(fen)級(ji)制度后加壓，分(fen)(fen)別是(shi)讀(du)取數(shu)據派出機(ji)關相電壓下微安表(biao)的穩定性讀(du)數(shu)。

4）測試安(an)全裝(zhuang)置階段中，應融洽竊(qie)聽被試品、測試安(an)全裝(zhuang)置安(an)全裝(zhuang)置、微(wei)安(an)表，己經引發擊穿電壓(ya)、忽明(ming)忽暗(an)等(deng)發現異常情況應請(qing)馬上減(jian)壓(ya)，鋸斷電源模塊，并查(cha)證誘因，詳細的(de)記(ji)錄時間(jian)。

5）經(jing)過多次實驗(yan)發現正在，降血壓，立即切斷主機電(dian)源后應將被試品及經(jing)過多次實驗(yan)發現系(xi)統設計(ji)本身就是有力釋放。

Ct——被試品的電容器量(pF)

ω——角頻(pin)點，ω=2πf， f——試驗臺電壓的頻(pin)點

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。

四、SFQ使用方法

為工作式(shi)產品。即3倍突(tu)發性生器(qi)(qi)和3倍頻保持儀器(qi)(qi)，并還擁(yong)有油煙凈(jing)化器(qi)(qi)保護(hu)好(hao)，相電壓(ya)電流表、3倍頻導出、相電壓(ya)表，以(yi)做監聽器(qi)(qi)和方便(bian)于(yu)采(cai)用，其(qi)保持儀器(qi)(qi)蓋(gai)板(ban)上(shang)接線圖(tu)柱與主機電源(yuan)接連辦法如(ru)下圖(tu)示圖(tu)圖(tu)示：

（按接(jie)線兩端圖將本試驗裝置是接(jie)入配電(dian)線路中，準備主設備一(yi)定接(jie)地）

本職工作電源適配器投(tou)入(ru)	三到五倍頻三相電輸入	兩相電150HZ	二相150HZ	接地極
220V220V	380V	顯示	模擬輸出

按詳細過程確(que)定實操：

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(bi)如在(zai)應力(li)測試方(fang)式中，被試品冒(mao)出匝(za)間(jian)、層間(jian)或段間(jian)、兩色相間(jian)耐壓(ya)穿透(tou)表(biao)現，則管理電(dian)路(lu)開關中應力(li)測試功率(lv)過大，繼電(dian)熱器可立(li)馬脫扣，關電(dian)。

５、校正完了，將調(diao)壓器退掉零位。

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％。
