Ibisobanuro bya tekiniki byo Gutahura Guhinduka kw'Ingufu za Transformer Ifite Voltage nyinshi

Ibisubizo bya JZP Transformer​

1. Intangiriro​

Guhindura imiterere y'imizunguruko mu buryo bwo hejuruTransformateur z'amashanyarazi ni ikibazo gikomeye ku mutekano, akenshi giterwa n’imbaraga za mekanike, imikorere y’ubushyuhe, cyangwa ingaruka za "short-circuit". Nk’umuyobozi mu gukora transformer, JZP ikurikiza amahame ya DL/T 1093-2018 yerekeye uburyo bwo gukora "Reactance Method" mu gushakisha "Winding Deformation" kandi ihuza ikoranabuhanga rigezweho kugira ngo igenzure ko iyubahirizwa kandi ko yizewe. Iyi nyandiko igaragaza ibisobanuro bya tekiniki bya JZP mu gushakisha "winding deformation", ikubiyemo uburyo, ibisabwa mu bikoresho, n’imikorere.

2. Ubuso​

Ibi bisobanuro bireba:

Ingano y'amashanyarazi: 35 kV no hejuru yayo.

Ubwoko bwa transformateur: Ibyiciro bitatu n'icyiciro kimwe Transformateur z'ingufu hamwe n'imiterere y'izunguruka ry'impande.

Uburyo bwo kumenya: Kwemerwa kw'uruganda, igenzura nyuma yo gutwara abantu, n'isuzuma ry'ibikorwa nyuma yo gusohora amashanyarazi.

3. Uburyo bwo Gutahura Ibyingenzi

3.1 Uburyo bwo Gusubiza (DL/T 1093-2018 Iyubahirizwa ry’amategeko)​

Ihame: Ipima impinduka mu mikorere y'ingufu (impedance) munsi ya voltage ya AC kugira ngo imenye ihindagurika rya mekanike.

Ibipimo by'ingenzi:

Ingano y'inshuro: 10 Hz - 1 MHz.

Uburinganire: ± 0.5% ku gaciro ka impedance.

Voltage y'igerageza: ≤2 kV (AC).

Ibyiza: Kuba umuntu ashobora kwiyumva cyane ku mpinduka nto (urugero, kugabanuka kwa impedance ya 0.1% bigaragaza ibibazo bishobora kubaho).

3.2 Isesengura ry'inshuro zisubirwamo (FRA)​

Uburyo: Guhindura umurongo kuva kuri 10 Hz kugeza kuri 20 MHz kugira ngo hagaragazwe imiterere y'impinduka.

Inyongera za JZP:

Ingero z'ingero zifite ubushobozi bwo gupima: amanota 50.000 y'amakuru yo gusesengura neza imiterere y'umuraba.

Igishushanyo mbonera cyo kurwanya ingaruka: Gukingira no gukingira kugira ngo bigabanye urusaku rw'amashanyarazi.

Umusaruro: Isesengura rigereranya imiterere y'amakuru y'igihe cya kera ugereranije n'iy'ubu kugira ngo hamenyekane impinduka mu misozo y'amajwi (urugero, >3 dB ihinduranya rituma habaho imenyesha).

4. Ibisabwa mu bya tekiniki​
5. Uburyo bwo gupima​

   5.1 Kwitegura mbere y'ikizamini​

    

   Igenzura ry'ibikoresho: Genzura uburyo sensor ipima (urugero, Rogowski coils kugira ngo ibone ibimenyetso bifite frequency yo hejuru).

    

   Imiterere ya transfoma: Menya neza ko transfoma yagabanutse ingufu kandi ko idafite aho ihuriye n'ubutaka.

    

   5.2 Ishyirwa mu bikorwa ry'ikizamini

    

   Imiterere y'insinga:

    

   Gufunga by'ibanze: Shyira ikimenyetso cy'igerageza (urugero, voltage ihoraho iva mu mwanya ufungura icyuma gihagarika uruziga).

    

   Ingufu zo mu rwego rwa kabiri: Huza sensor kugira ngo upime ibimenyetso byatewe.

    

   Igenamiterere rya parametero:

    

   Intambwe zo gupima inshuro: Gukwirakwiza Logarithmike kugira ngo habeho inkuru yuzuye.

    

   Imipaka y'ibitera imbaraga: Hindura byikora hashingiwe ku bushobozi bwa transformateur (urugero, transformateur za 110 kV zikenera ubushobozi bwa 100 ×).

    

   Kubona amakuru:

    

   Fata ingero zirenga 200 kuri buri gahunda.

    

   Igaragaza ry'ubunini bwa impedance/inguni y'icyiciro mu gihe nyacyo.

    

   5.3 Isesengura rya nyuma y'ikizamini​

    

   Gusuzuma indwara hifashishijwe ikoranabuhanga:

    

   Gereranya ukoresheje umwimerere w’uruganda (urugero, kunyuranya kw’impedansi >2% bigaragaza guhinduka).

    

   Ishusho ya 3D yerekana ikwirakwizwa ry'imitsi izunguruka.

    

   Gutanga raporo: Gukora raporo z'iyubahirizwa ry'amategeko hamwe n'imbonerahamwe n'inama zishobora gukurikizwa.

    

   6. Inyigo y'Urugero: Transformer yo mu murima w'umuyaga​

    

   Ishusho: Transformateur y'umuyaga ya 33 kV yagaragaje ihindagurika rya impedance rya 15% nyuma y'imvura.

    

   Igisubizo cya JZP:

    

   Hakozwe ikizamini cya FRA, hagaragazwa impinduka y’umuvuduko wa resonance ya 4 kHz.

    

   Hagaragajwe uburyo igice cy'izunguruka cyagaragaye binyuze mu ifoto y'ubushyuhe ya 3D.

    

   Turasaba gusubira inyuma, hirindwa ko habaho gutsindwa gukomeye.

    

   7. Iyubahirizwa ry'amategeko n'iyubahirizwa ry'amategeko​

    

   Amabwiriza mpuzamahanga: IEC 60076-18, IEEE C57.152.

    

   Impamyabushobozi: CE, UL, ISO 9001.

    

   Kwemeza kw'umuntu wa gatatu: Igenzura rya buri mwaka ryakozwe na TÜV Rheinland.

    

   8. Umwanzuro​

    

   Sisitemu ya JZP yo gupima imiterere y’impinduka ihuza gupima neza, gusesengura bishingiye ku buhanga bwa AI, no kubahiriza byimazeyo DL/T 1093-2018. Dukoresheje ikoranabuhanga rigezweho nka FRA ikoresha inshuro nyinshi na raporo zikora, twemeza ko transformers zikora neza kandi mu mutekano mu mishinga yose ku isi.
