Kuzindikira Kusinthika kwa Mphamvu ya Voltage Transformer Yopindika Kwambiri

Mayankho a JZP Transformer

1. Chiyambi​

Kusintha kwa ma winding mu high-Ma Transformers a Voltage ndi vuto lalikulu la chitetezo, lomwe nthawi zambiri limayamba chifukwa cha kupsinjika kwa makina, kutentha kwa mpweya, kapena kukhudzidwa ndi ma transformer afupikitsa. Monga mtsogoleri pakupanga ma transformer, JZP imatsatira DL/T 1093-2018 Standard for Reactance Method mu Winding Deformation Detection ndipo imagwirizanitsa ukadaulo wapamwamba kuti zitsimikizire kuti zikutsatira malamulo ndi kudalirika. Chikalatachi chikufotokoza zaukadaulo wa JZP wozindikira kusintha kwa ma winding, kuphatikiza njira, zofunikira pazida, ndi njira zogwirira ntchito.

2. Chigawo​

Mfundo imeneyi ikugwira ntchito pa:

Mphamvu yamagetsi: 35 kV ndi kupitirira apo.

Mitundu ya Transformer: Gawo lachitatu ndi gawo limodzi Zosinthira Mphamvu yokhala ndi mawonekedwe ozungulira ozungulira.

Zochitika zozindikira: Kuvomerezedwa ndi fakitale, kuwunika pambuyo pa mayendedwe, ndi kuwunika zochitika pambuyo pa mayendedwe afupiafupi.

3. Njira Zodziwira Makiyi​

3.1 Njira Yochitira Zinthu (DL/T 1093-2018 Compliance)​

Mfundo: Imayesa kusintha kwa kayendedwe ka kuzungulira (impedance) pansi pa mphamvu ya AC kuti izindikire kusokonekera kwa makina.

Magawo ofunikira:

Mafupipafupi: 10 Hz - 1 MHz.

Kulondola: ± 0.5% ya mtengo wa impedance.

Voliyumu yoyesera: ≤2 kV (AC).

Ubwino: Kuzindikira kwambiri kusintha pang'ono kwa magetsi (monga, kupotoka kwa impedance kwa 0.1% kumasonyeza mavuto omwe angakhalepo).

3.2 Kusanthula Mayankho Obwerezabwereza (FRA)​

Njira: Imasefa ma frequency kuyambira 10 Hz mpaka 20 MHz kuti ijambule mawonekedwe a winding resonance.

Zowonjezera za JZP:

Kusankha zitsanzo zapamwamba kwambiri: mfundo 50,000 za data kuti muwunike bwino mawonekedwe a mafunde.

Kapangidwe koletsa kusokoneza: Kudzipatula ndi kuteteza kuwala kuti muchepetse phokoso lamagetsi.

Zotsatira: Kusanthula koyerekeza kwa ma spectra afupipafupi a mbiri yakale motsutsana ndi amakono kuti tizindikire kusintha kwa ma resonance peaks (monga, >3 dB variation imayambitsa machenjezo).

4. Zofunikira zaukadaulo​
5. Njira Yoyesera​

   5.1 Kukonzekera Mayeso Asanayambe​

    

   Kuyang'ana zida: Tsimikizirani kuwerengera kwa sensa (monga Rogowski coils kuti muwone ngati pali zizindikiro zama frequency apamwamba).

    

   Mkhalidwe wa transformer: Onetsetsani kuti transformer yachotsedwa mphamvu ndipo yakhazikika pansi.

    

   5.2 Kuyesa Kuyesedwa​

    

   Kapangidwe ka mawaya:

    

   Kuzungulira koyambirira: Ikani chizindikiro choyesera (monga, mphamvu yamagetsi yochokera ku kutsegula kwa chotseka ma circuit).

    

   Kuzungulira kwachiwiri: Lumikizani masensa kuti muyese zizindikiro zoyambitsidwa.

    

   Zokonda za magawo:

    

   Masitepe ojambulira pafupipafupi: Kugawa kwa Logarithmic kuti mudziwe zambiri.

    

   Zolepheretsa: Sinthani zokha kutengera mphamvu ya transformer (monga, ma transformer a 110 kV amafunika mphamvu ya 100 ×).

    

   Kupeza deta:

    

   Jambulani zitsanzo zoposa 200 pa nthawi iliyonse.

    

   Kuwonetsera kwa nthawi yeniyeni kwa mphamvu ya impedance/gawo.

    

   5.3 Kusanthula Pambuyo pa Mayeso​

    

   Kuzindikira matenda mwaokha:

    

   Yerekezerani ndi maziko a fakitale (mwachitsanzo, kupotoka kwa impedance >2% kumasonyeza kusintha).

    

   Mapu a 3D a kugawa kwa kupsinjika kozungulira.

    

   Kupereka Malipoti: Kupanga malipoti otsatira malamulo okhala ndi ma graph ndi malangizo oti agwire ntchito.

    

   6. Phunziro la Nkhani: Chosinthira cha Famu ya Mphepo​

    

   Chitsanzo: Chosinthira cha mphepo cha 33 kV chinawonetsa kupotoka kwa impedance kwa 15% pambuyo pa chimphepo chamkuntho.

    

   Yankho la JZP:

    

   Ndinayesa FRA, ndipo ndinapeza kusintha kwa 4 kHz resonance peak.

    

   Kuzindikira kusamuka pang'ono kwa mlengalenga pogwiritsa ntchito zithunzi za kutentha za 3D.

    

   Kulimbikitsa kubwereranso, kupewa kulephera kwakukulu komwe kungachitike.

    

   7. Kutsatira Malamulo ndi Chitsimikizo​

    

   Miyezo yapadziko lonse: IEC 60076-18, IEEE C57.152.

    

   Ziphaso: CE, UL, ISO 9001.

    

   Kutsimikizira kwa chipani chachitatu: Kuwunika kwa pachaka kwa TÜV Rheinland.

    

   8. Mapeto​

    

   Dongosolo lozindikira kusintha kwa maginito la JZP limaphatikiza muyeso wolondola, kusanthula koyendetsedwa ndi AI, komanso kutsatira kwathunthu DL/T 1093-2018. Mwa kuphatikiza ukadaulo wapamwamba monga FRA yapamwamba komanso malipoti odziyimira pawokha, timaonetsetsa kuti ma transformer amagwira ntchito mosamala komanso moyenera pamapulojekiti apadziko lonse lapansi.
