Izixazululo ze-JZP Transformer​

1. Isingeniso​

Ukuguqulwa kokujikeleza okuphezuluAma-Voltage Transformers Kuyinkinga enkulu yokuphepha, evame ukubangelwa ukucindezeleka komshini, ukujikeleza kokushisa, noma imithelela ye-short-circuit. Njengomholi ekukhiqizweni kwe-transformer, i-JZP inamathela ku-DL/T 1093-2018 Standard for Reactance Method in Winding Deformation Detection futhi ihlanganisa ubuchwepheshe obuthuthukisiwe ukuqinisekisa ukuhambisana nokuthembeka. Lo mbhalo uchaza imininingwane yobuchwepheshe ye-JZP yokuthola ukuguqulwa kokushintsha, uhlanganisa izindlela, izidingo zemishini, kanye nezinqubo zokusebenza.

2. Ububanzi​

Le ncazelo isebenza ku:

3. Izindlela Zokuthola Ukhiye​

3.1 Indlela Yokusabela (DL/T 1093-2018 Ukuthobela)​

Isimiso: Ilinganisa izinguquko ekuphenduleni okugoqekayo (impedance) ngaphansi kwe-voltage ye-AC ukuze ithole ukuphazamiseka komshini.

Amapharamitha ayisihluthulelo:

Ibanga lokuvama: 10 Hz - 1 MHz.

Ukunemba: ± 0.5% yamanani e-impedance.

I-voltage yokuhlola: ≤2 kV (AC).

Izinzuzo: Ukuzwela okuphezulu ekuguqukeni okuncane (isb., ukuphambuka kwe-impedance okungu-0.1% kubonisa izinkinga ezingaba khona).

3.2 Ukuhlaziywa Kwempendulo Ephindaphindayo (i-FRA)​

Indlela Yokwenza: Ishanela amaza omsindo asukela ku-10 Hz kuya ku-20 MHz ukuze ibambe izici zomsindo ojikelezayo.

Ukuthuthukiswa kwe-JZP:

Isampula enesinqumo esiphezulu: amaphuzu edatha angu-50,000 okuhlaziywa kwesimo samagagasi okunembile.

Umklamo ovimbela ukuphazamiseka: Ukuhlukanisa okubonakalayo kanye nokuvikela ukunciphisa umsindo we-electromagnetic.

Umphumela: Ukuhlaziywa kokuqhathanisa kwama-spectra emvamisa yomlando vs. yamanje ukuze kutholakale ukushintsha kweziqongo ze-resonance (isb., izexwayiso zokushintshashintsha kwe->3 dB).

4. Izidingo Zobuchwepheshe​
5. Inqubo Yokuhlola​

   5.1 Ukulungiselela Ngaphambi Kokuhlolwa​

    

   Ukuhlolwa kwemishini: Qinisekisa ukulinganiswa kwenzwa (isb., amakhoyili eRogowski ukuze uthole amasignali asebenza ngesivinini esiphezulu).

    

   Isimo se-transformer: Qinisekisa ukuthi i-transformer ayinamandla futhi ayigxilile.

    

   5.2 Ukuhlolwa Kwenziwe​

    

   Ukucushwa kwezintambo:

    

   Ukugoqa okuyinhloko: Sebenzisa isignali yokuhlola (isb., i-voltage transient evela ekuvulekeni kwe-circuit breaker).

    

   Ukujikeleza kwesibili: Xhuma izinzwa ukuze ulinganise izimpawu ezibangelwayo.

    

   Izilungiselelo zepharamitha:

    

   Izinyathelo zokuskena imvamisa: Ukusatshalaliswa kwe-Logarithmic ukuze kuhlanganiswe ngokuphelele.

    

   Izingqimba ze-trigger: Lungisa ngokuzenzakalelayo ngokusekelwe kumthamo we-transformer (isb., ama-transformer angu-110 kV adinga ukuzwela okungu-100×).

    

   Ukutholwa kwedatha:

    

   Thwebula amasampula angaphezu kuka-200 ngephuzu ngalinye lemvamisa.

    

   Ukuboniswa kwesikhathi sangempela kobukhulu be-impedance/i-engeli yesigaba.

    

   5.3 Ukuhlaziywa Kwangemva Kokuhlolwa​

    

   Ukuxilongwa okuzenzakalelayo:

    

   Qhathanisa nesisekelo semboni (isb., ukuphambuka kwe-impedance >2% kubonisa ukuguqulwa).

    

   Imephu ye-3D yokusatshalaliswa kokucindezeleka okugoqekayo.

    

   Ukubika: Khiqiza imibiko yokuthobela imithetho ngamagrafu nezincomo ezingasetshenzwa.

    

   6. Ucwaningo Lwesibonelo: Isiguquli Sepulazi Lomoya​

    

   Isimo: I-transformer yepulazi lomoya engu-33 kV ibonise ukuphambuka kwe-impedance okungu-15% ngemva kwesiphepho.

    

   Isixazululo sikaJZP:

    

   Kwenziwe ukuhlolwa kwe-FRA, kwembulwa ukushintsha kwe-resonance peak okungu-4 kHz.

    

   Kutholwe ukufuduka okuyingxenye kokugoba ngesithombe sokushisa se-3D.

    

   Kunconywa ukuhlehlisa, ukuvimbela ukwehluleka okungaba yinhlekelele.

    

   7. Ukuthobela imithetho kanye nesitifiketi​

    

   Izindinganiso zomhlaba wonke: IEC 60076-18, IEEE C57.152.

    

   Izitifiketi: CE, UL, ISO 9001.

    

   Ukuqinisekiswa komuntu wesithathu: Ukuhlolwa kwaminyaka yonke yi-TÜV Rheinland.

    

   8. Isiphetho​

    

   Uhlelo lokuthola ukuguqulwa kwe-JZP luhlanganisa ukulinganisa okunembile, ukuhlaziya okuqhutshwa yi-AI, kanye nokuhambisana ngokugcwele ne-DL/T 1093-2018. Ngokuhlanganisa ubuchwepheshe obusezingeni eliphezulu njenge-FRA evame kakhulu kanye nokubika okuzenzakalelayo, siqinisekisa ukuthi ama-transformer asebenza ngokuphepha nangokusebenza kahle kuwo wonke amaphrojekthi omhlaba.
