transformateur ya voltage ntoya hamwe na voltage ya 0.4 / 0.23 kV nigikoresho cyihariye cyamashanyarazi
yagenewe gutanga ubwigunge bwa galvanic hagati yimirongo ibiri. Bikunze gukoreshwa mu nganda, mu bucuruzi,
nibisabwa gutura kugirango umutekano ubungabunge, kugabanya urusaku rwamashanyarazi, no kurinda ibikoresho byoroshye
ihindagurika rya voltage cyangwa hejuru.
Igikorwa cyibanze cyiyi transformateur ni ukumanura voltage kuva 0.4 kV (400 V) ikagera kuri 0.23 kV (230
V) mugihe ukomeje kwigunga amashanyarazi yuzuye hagati yinjiza (primaire) nibisohoka (secondaire)
Kuzunguruka. Uku kwigunga kubuza guhuza amashanyarazi mu buryo butaziguye, kugabanya ibyago byo guhitanwa n amashanyarazi no gutera imbere
umutekano rusange muri sisitemu. Byongeye kandi, ifasha gukuraho ibibanza byubutaka, bishobora gutera kwivanga muburyo bworoshye
ibikoresho bya elegitoroniki.
Yubatswe hamwe nibikoresho byujuje ubuziranenge, transformateur iranga intangiriro ikomeye ikozwe muri silicon yanduye
ibyuma kugirango ugabanye ingufu zitakaza ingufu kandi ukore neza. Guhinduranya byitondewe neza
ihangane n'ubushyuhe bwo hejuru kandi utange igihe kirekire. Igishushanyo kirimo kandi kurinda ubushyuhe
uburyo bwo kwirinda ubushyuhe munsi yumutwaro uremereye.

Imashini ihinduranya imashini (OLTC) ihinduranya amavuta ni impinduka ikomeye mugusaranganya ingufu
sisitemu, yagenewe kugenzura urwego rwa voltage mugihe gikomeza gutanga amashanyarazi. Ubu bwoko bwa
transformateur ifite ibikoresho byahinduwe bihindura igipimo cyo guhinduranya munsi yumutwaro, byemeza ko bihamye
ibisohoka voltage nubwo ihindagurika ryinjiza voltage cyangwa imiterere yimitwaro. Igipimo cya 35 / 0.4 kV kirabigaragaza
kumanuka kumashanyarazi menshi kuva kuri 35 kV kugeza kuri voltage 0.4 kV, bigatuma bikwiranye ninganda na
gusaba ubucuruzi.
Impinduka ya transformateur ikozwe mubyuma byo mu rwego rwo hejuru bya silicon, bigabanya igihombo cyicyuma, mugihe kizunguruka
zubatswe kuva umuringa cyangwa aluminium kugirango ugabanye igihombo cyumuringa. Uburyo bwa OLTC butanga igihe-nyacyo
Guhindura voltage, mubisanzwe murwego rwa ± 10% kugeza ± 15%, byemeza imikorere myiza no guhuza
hamwe n'ibisabwa bitandukanye. Iyi mikorere ni ingirakamaro cyane mubice bifite imiterere idahwitse ya gride.
Gukwirakwiza ni ikintu cy'ingenzi mu gishushanyo mbonera cyacyo, hamwe n'umuyaga winjijwe mu mavuta y'amabuye y'agaciro kugira ngo ukonje kandi
Indangabintu. Amavuta nayo akora nka dielectric medium, irinda arcing imbere no kwagura
ubuzima bwa transformateur. Byongeye kandi, transformateur ifite ibikoresho byo kurinda nka Buchholz
relay hamwe nigitutu cyo kugabanya igitutu kugirango ikore neza.

Impinduramatwara-yashizwemo amavuta nubwoko bwa transformateur ikoresha ingufu zikoresha amavuta nka coolant na an
iringaniza. Amavuta afasha gukwirakwiza ubushyuhe butangwa mugihe cyo gukora kandi butanga amashanyarazi
hagati yizunguruka hamwe na transformateur yibanze. Igishushanyo gikoreshwa cyane mugukwirakwiza ingufu kandi
sisitemu yo kohereza kubera kwizerwa no gukora neza.
Transformator ifite igipimo cya voltage ya 35 / 0.4 kV ikoreshwa muburyo bwo gukwirakwiza. Umuvuduko mwinshi
uruhande (35 kV) rwahujwe na gride y'amashanyarazi, mugihe uruhande ruke rwa voltage (0.4 kV) rutanga amashanyarazi kubarangije,
nk'ibikoresho byo guturamo, ubucuruzi, cyangwa inganda. Iboneza rya voltage nibyiza gutera intambwe
munsi ya voltage yo hagati kugeza kuri voltage nkeya kugirango ukoreshwe hafi.
Impinduramatwara yibitseho amavuta izwiho kubaka imbaraga nubushobozi bwo gutwara imitwaro myinshi. Bo
Byashizweho hamwe nibyuma bikozwe mubyuma bya silicon byacishijwe bugufi kugirango bigabanye igihombo hamwe nizunguruka bikozwe mu muringa
cyangwa aluminium yohereza ingufu neza. Amavuta akingira kandi yongerera igihe ubuzima bwa transformateur
kurinda ibice byimbere mubushuhe na okiside.

Imashini yumye yumye ni transformateur yamashanyarazi ikoresha umwuka nkuburyo bukonjesha aho gukoresha amazi
(nk'amavuta). Ikoreshwa cyane mubikorwa byo murugo kubera umutekano wacyo, kubungabunga ibidukikije, no hasi
ibisabwa byo kubungabunga. Transformator ya 35 / 0.4 kV yumye yashizweho kugirango igabanye ingufu za voltage nyinshi (35
kV) kugeza kuri voltage nkeya (0.4 kV), bigatuma ikwirakwizwa ryinganda, ubucuruzi, n’imiturire
Sisitemu.
Transformator ikora idafite amazi yaka, ikuraho ingaruka zumuriro n ibidukikije
kwanduza. Ibi bituma biba byiza mububiko, ibitaro, amashuri, nahandi hantu hahurira abantu benshi
aho umutekano ariwo wambere. Ubwubatsi bwayo bukomeye butanga imikorere yizewe no mubidukikije bikaze,
hamwe no guhangana cyane nubushuhe, ivumbi, nihindagurika ryubushyuhe.

S11 / S13 - M.RL ikurikirana ya 10kV urwego rukomeye rwimikorere ni igicuruzwa gishya cyateye imbere, kimeneka
binyuze mumiterere gakondo ya planari kandi ifata ibyiciro bitatu byuburinganire bukomeye.
Kandi kubera ko nta cyuho cyumuyaga kiri mumuzunguruko, guhinduranya ni byinshi, magnetique
icyerekezo cyicyerekezo cyicyuma cya silicon irahuye rwose, inkingi eshatu zingenzi zitunganijwe
inyabutatu iringaniye ikomeye, imirongo itatu ya magnetique ifite uburebure bumwe, kandi byose ni bigufi, na
gutunganya no guteramo nta bikoresho;
Kubwibyo, ni transformateur ikora neza kandi ikiza ingufu ikoresha ibikoresho gakondo, ariko ifite hasi
urusaku rukora nuburyo bworoshye.

S13 yamavuta yinjizwamo imbaraga ni transformateur ihuza transformateur hamwe nayo
ibikoresho byingirakamaro, byashyizwe munsi yububiko bwo hanze budafite aho buhurira nabantu,
kandi irashobora kwibizwa mumazi mugihe runaka. Transformator yo munsi y'ubutaka ifite imikorere
yo gukwirakwiza amashanyarazi kandi irashobora gusimbuza insimburangingo gakondo kandi ikoreshwa cyane muri parike yinganda kandi
ahantu ho gutura.
Ubushobozi Bwinshi Bwimbaraga: Iyi 110kv ibyiciro bitatu byimpinduka zingufu zifite ubushobozi buke bwa 2, 6, 8, na
10 MVA, kuyigira ihitamo ryiza kubisaba imbaraga nyinshi, nkuko byasabwe nabakiriya bashaka kwizerwa kandi
igisubizo cyiza.
Amahitamo atandukanye ya voltage: Hamwe nurwego rwibanze rwambere na kabiri rwamahitamo, harimo 110kv, 115kv,
138kv, na 69kv, iyi transformateur irashobora kwinjizwa byoroshye mumashanyarazi atandukanye, igaburira ibintu bitandukanye
ibyo umukiriya akeneye nibyo akunda.
