VLF CR-28便攜(xie)式智能型電(dian)纜交流耐壓試驗(yan)

VLF CR-40便攜式(shi)智能(neng)型電纜(lan)交流耐壓試驗

VLF CR-60便攜式智能型電纜交流耐壓試驗

·  ;       同一臺儀器，可(ke)進(jin)行三類耐(nai)壓試(shi)驗：超低頻0.1 Hz交流(liu)；直流(liu)DC；外護套耐(nai)壓

·           超(chao)輕便(bian)，兩節式zhuanli設計

·           0.1 Hz試驗頻率下超大試驗容量

·      ;     內置(zhi)自動放(fang)電單元，更(geng)安全

·    ;       計算機導(dao)出試驗報告

根據(ju)電(dian)(dian)(dian)(dian)工(gong)委(wei)員會IEC60060標準、電(dian)(dian)(dian)(dian)氣(qi)電(dian)(dian)(dian)(dian)子工(gong)程師協會IEEE400-2001標準，余弦方(fang)波超低頻0.1Hz電(dian)(dian)(dian)(dian)纜耐(nai)(nai)(nai)壓試(shi)(shi)(shi)驗(yan)方(fang)法具有(you)便攜式、高試(shi)(shi)(shi)驗(yan)容(rong)量、低功耗等技術(shu)優勢，可以(yi)用來(lai)對電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜做耐(nai)(nai)(nai)壓試(shi)(shi)(shi)驗(yan)。根據(ju)上述規程和中國(guo)GB50150-2006國(guo)家標準規定，電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜輸配(pei)電(dian)(dian)(dian)(dian)線路在新設竣工(gong)或(huo)檢修完畢后必須進行耐(nai)(nai)(nai)壓試(shi)(shi)(shi)驗(yan)，檢查絕緣層耐(nai)(nai)(nai)壓和擊穿電(dian)(dian)(dian)(dian)場強度。

由于采用了(le)余(yu)弦方波和能(neng)量(liang)循環(huan)zhuanli技術，0.1 Hz電纜交(jiao)流耐(nai)(nai)壓試(shi)驗(yan)(yan)(yan)產品(pin)兼有高試(shi)驗(yan)(yan)(yan)容量(liang)和緊湊(cou)型的雙(shuang)重優(you)點(dian)(dian)(dian)。 除了(le)能(neng)做電纜絕緣(yuan)層和外護套(tao)耐(nai)(nai)壓試(shi)驗(yan)(yan)(yan)以外，0.1 Hz耐(nai)(nai)壓試(shi)驗(yan)(yan)(yan)產品(pin)還(huan)能(neng)對外護套(tao)缺陷點(dian)(dian)(dian)進行智(zhi)能(neng)跨(kua)步(bu)法精(jing)確定點(dian)(dian)(dian) （脈動發生器內(nei)置(zhi)在(zai)0.1 Hz試(shi)驗(yan)(yan)(yan)產品(pin)機箱(xiang)內(nei)，需要另(ling)配(pei)ESG NT智(zhi)能(neng)跨(kua)步(bu)法定點(dian)(dian)(dian)儀(yi)）。

便攜式(shi)智能型電纜0.1 Hz交流耐壓試驗產品包括以下三個型號，大輸(shu)出電壓(有效值)分(fen)別是28 kV, 40 kV, 60 kVrms,:

- VLF CR-28 適合額定電壓10 kV及以下電力電纜
- VLF CR-40 適合額定電壓20 kV及以下電力電纜
- VLF CR-60 適合額定電壓35 kV及以下電力電纜
