Amabwiriza Mpuzamahanga y'Ubwinshi bw ... n'Ubuyobozi bwo Guhitamo Transformer y'Ubwinshi bw'Ubwinshi

1. Ishyirwa mu byiciro rya Voltage n'inshingano za Transformer​

 

Transformateur z'amashanyarazi menshi (HV) zakozwe ku muvuduko wa ≥35 kV (Amerika y'Amajyaruguru) cyangwa ≥36 kV (Uburayi), zikoreshwa cyane cyane mu miyoboro y'amashanyarazi kugira ngo zongere umusaruro wa generator mu gutanga amashanyarazi kure no kugabanya amashanyarazi ku mashanyarazi. Mu buryo bunyuranye, transformateur z'amashanyarazi make (LV) (≤1 kV) zikora ku buryo bwo gukwirakwiza amashanyarazi mu gace ziherereyemo, zigabanya amashanyarazi ku rugero rushoboka mu ngo, mu bucuruzi no mu nganda. Transformateur z'amashanyarazi ziganje mu mikoreshereze ya HV (urugero, 110–765 kV), mu gihe Transformateur yo gukwirakwizakwibanda kuri sisitemu za LV (≤33 kV).

 

2. Amabwiriza y'ingufu z'amashanyarazi mu karere n'ikoreshwa ryazo​

 

Ubushinwa: Bukoresha ikoranabuhanga rinini cyane ku isi rya UHV DC (± 1100 kV) mu kohereza ingufu z'amashanyarazi mu burengerazuba bw'iburasirazuba. Uturere tw'icyaro twishingikiriza kuri transfoma za 10 kV/0.4 kV mu gutanga amashanyarazi.

 

Amerika ya Ruguru: Ikoresha kV 138–765 mu gutwara abantu. Imbuga z'umuyaga zo muri Texas zikenera transformateur nini zifite ubushobozi bwa kV 345. Imiterere y'imashini zigabanyamo ibice (240V zikozwe hagati) ni ibisanzwe ku miyoboro yo guturamo.

 

Uburayi: Ishyira imbere ibishushanyo mbonera birengera ibidukikije, nka ester-Transformateur y'amavutas na smart grids (urugero, umushinga w’Ubudage wa E-Energy). Imbuga z’umuyaga zo mu nyanja y’Amajyaruguru zikoresha sitasiyo za 66–220 kV.

 

Ubuyapani: Ifite transformateur zirwanya imitingito zifite uduce tworoshye tworoshye hamwe na sisitemu zidasanzwe zo guturamo za 100V. Transformateur zifite umurongo ubiri (50/60 Hz) zirakenewe kugira ngo iburasirazuba n'iburengerazuba bihuzwe n'umuyoboro w'amashanyarazi.

 

Ubuhinde: Buteza imbere transfoma zidafite isura ihagije kugira ngo bugabanye igihombo ku kigero cya 70% kandi bugakemura ikibazo cyo gukwirakwiza amashanyarazi mu cyaro hakoreshejwe sisitemu ya 11 kV/230V.

 

3. Ibipimo ngenderwaho byo guhitamo tekiniki

 

Guhuza Voltage: Menya neza ko ± 0.5% nta mutwaro urimo kandi ko ± 1% yihanganira umutwaro wose hakurikijwe IEC 60076. Sisitemu z'ingufu zivugururwa (urugero, imirima y'izuba) zishobora gusaba uburyo bwo kugenzura ± 10%.

 

Ubushobozi n'Umutwaro: Koresha formula S=3×U×Ito kugirango ubare kVA. Gumana umutwaro w'igihe kirekire hagati ya 60–80% kugira ngo ubone umusaruro mwiza. Imitwaro ihoraho (urugero: metallurgy) isaba ubushobozi bwo kurenza 115% mu gihe cy'isaha 1.

 

Gushyiramo ubushyuhe n'ubukonje:

 

Irimo amavuta: Ihendutse ku miyoboro yo hanze ariko ikenera uburyo bwo kuzimya inkongi.

 

Ubwoko bwumutse (Resin): Irinda umuriro kandi ntiyitaho cyane, ni nziza ku nyubako ariko ihenze cyane 30%.

 

Gazi ya SF₆: Irinda umwanda ku masitasiyo manini yo mu mijyi ariko iragenzurwa n'ibidukikije.

 

Amabwiriza agenga imikorere myiza:

 

Igipimo cya mbere cya GB 20052 cyo mu Bushinwa cyagabanyije igihombo ku kigero cya 40% ugereranije n'icya 3.

 

Amabwiriza yo ku rwego rwa 3 rw'Umuryango w'Ubumwe bw'u Burayi azakuraho uburyo budakora neza bitarenze umwaka wa 2025.

 

4. Ibibazo Bisanzwe n'Ibisubizo​

 

Gushyira mu byiciro bitari byo: Gukoresha transfoma za LV mu miyoboro ya HV bitera ubushyuhe bwinshi no kunanirwa gushyushya insulation. Shyira ku rugero rwa 66 kV.

 

Iyubahirizwa ry’amategeko mu Karere: Amategeko agenga imikorere myiza ya Amerika y’Amajyaruguru agenga imikorere myiza atandukanye n’ay’icyiciro cya 2 cy’Ubumwe bw’u Burayi mu bijyanye no gushushanya ibidukikije. Isuzuma ry’abantu ba gatatu (urugero, raporo za CTI/STL) rituma hubahirijwe iyubahirizwa ry’amategeko.

 

Guhuza ibidukikije:

 

Ubutumburuke Burebure: Gutakaza ubushobozi bwabyo ho 5%/500m (urugero: imishinga ya Andean).

 

Kwangirika: Udusanduku tw'icyuma kidashonga n'udupira tw'icyiciro cya gatatu bigabanya kwangirika kw'umunyu.

 

5. Ingendo zigenda zizamuka​

 

Udukoresho tw’ikoranabuhanga: Sisitemu zo kugenzura mu buryo bwihuse i Burayi hamwe no kubungabunga amakuru ashingiye ku buhanga bwa AI binoza imikorere ya transformer.

 

Guhuza Ibishobora Gusubiramo: Ibigo by'umuyaga byo mu mazi n'inganda zikoresha imirasire y'izuba bituma hakenerwa transfoma za 35–132 kV zifite ubushobozi bwo guhangana n'imihindagurikire y'ikirere (K≥13).

 

Kuramba: Ingufu zidafite isura nziza, amavuta ya ester ashobora kubora, n'ibikoresho bishobora kongera gukoreshwa bihindura imiterere y'ibikenewe mu igenamigambi.

 

Ibintu by'ingenzi byafashwe

 

Icyibandwaho mu gishushanyo: Transformateur za HV zishyira imbere imbaraga zo gukingira no gucunga ubushyuhe, mu gihe transformateur za LV zishimangira ubucucike n'umutekano.

 

Iyubahirizwa ry’amategeko mpuzamahanga: Amabwiriza nka IEC 60076 (HV) na UL/CE (akarere) ategeka isuzuma rikomeye ry’ubudahangarwa bw’amashanyarazi n’ubudahangarwa bw’ibidukikije.

 

Ikiguzi cy'ubuzima: Uburyo bukoresha ikoranabuhanga rigezweho (urugero, amorphous-core) butanga umusaruro mu myaka 3 binyuze mu kuzigama ingufu, nubwo ibiciro bya mbere byari byinshi.

 

Ku bijyanye n'ibisubizo byihariye, gisha inama abatanga serivisi nka Energy Transformer, batanga serivisi zo guhindura ibintu mu buryo butaziguye mu ruganda no kwemeza ko amategeko yubahirizwa ku rwego mpuzamahanga.
