Kuki kubungabunga transformateur ari ngombwa?

1. Intego n'imiterere yatransformateurkubungabunga
a. Intego yo kubungabunga transformateur
Intego y'ibanze yo kubungabunga transformateur ni ukureba neza ko transformateur n'ibindi bikoresho by'imbere n'inyuma ibiceBibikwa neza, "bikwiriye uwo murimo" kandi bishobora gukora mu mutekano igihe icyo ari cyo cyose. Ikindi cy'ingenzi ni ugukomeza kwandika amateka y'imiterere ya transformer.

b. Impapuro zo kubungabunga transformer
Transformateur zikoresha ingufu zikenera imirimo itandukanye yo kubungabunga, harimo gupima no kugerageza ibipimo bitandukanye bya transformateur. Hari ubwoko bubiri bw'ibanze bwo kubungabunga transformateur. Dukora itsinda rimwe rimwe (ryitwa preventive maintenance) n'irya kabiri ku buryo budasanzwe (ni ukuvuga igihe cyose bikenewe).

2. Igenzura rya buri kwezi ry’imicungire y’ibikoresho bihindura imikorere
– Igipimo cy'amavuta mu gipfundikizo cy'amavuta kigomba kugenzurwa buri kwezi kugira ngo kitagwa munsi y'umupaka ugenwe, bityo ibyangirika bitewe na yo bikaba birindwa.

- Komeza ugire imyobo yo guhumeka iri mu muyoboro wa silica gel uhumeka isuku kugira ngo uhumeke neza.

- Nibatransformateur y'amashanyaraziifite ibihuru byuzuye amavuta, menya neza ko amavuta yuzuye neza.

Iyo bibaye ngombwa, amavuta azuzura mu gipangu kugeza ku rwego rukwiye. Kuzuza amavuta bikorwa mu gihe cyo kuzimya.

3. Gutunganya no kugenzura buri munsi
– Soma MOG (Igipimo cy'amavuta ya Magnetic) cy'ikigega kinini n'ikigega cyo kubikamo.

- Ibara rya gel ya silica iri mu mwuka.

- Amavuta asohoka aturutse aho ari ho hose muri transformateur.

Mu gihe habayeho urwego rudashimishije rw'amavuta muri MOG, amavuta agomba kuzuzwa muri transformateur, kandi ikigega cyose cya transformateur kigomba kugenzurwa niba nta mavuta yamenetse. Niba hagaragaye ko hari amavuta yamenetse, fata ingamba zikenewe kugira ngo ufunge ayo mavuta. Niba gel ya silica ihindutse umutuku muto, igomba gusimbuzwa.

4. Gahunda y'ibanze y'ibikorwa byo kubungabunga transformateur buri mwaka
– Imikorere ya sisitemu yo gukonjesha yikora, ikoresha kure, n'ikoresha intoki bivuze ko pompe z'amavuta, abafana b'umwuka, n'ibindi bikoresho bifatanya na sisitemu yo gukonjesha ya transformer n'umuyoboro w'igenzura. Bizasuzumwa mu gihe cy'umwaka umwe. Mu gihe habayeho ikibazo, suzuma umuyoboro w'igenzura n'imiterere y'ipompe n'umufana.

- Ibice byose bya transformer bigomba gusukurwa n'igitambaro cyoroshye cya kotoni buri mwaka. Mu gihe cyo gusukura ibice bigomba kugenzurwa ko nta mivuniko.

- Imiterere y'amavuta ya OLTC izagenzurwa buri mwaka. Kubwibyo, icyitegererezo cy'amavuta kizavanwa mu muyoboro w'amazi wo mu kigega gitandukanya, kandi iki cyitegererezo cy'amavuta yakusanyijwe kizapimwa imbaraga za dielectric (BDV) n'ubushuhe (PPM). Niba BDV ari nke, kandi PPM y'ubushuhe ikaba iri hejuru y'agaciro kagenwe, amavuta ari muri OLTC agomba gusimbuzwa cyangwa kuyungururwa.

- Igenzura rya Buchholz mu buryo bwa mekanikerelaysbikorwa buri mwaka.

- Ibikoresho byose bigomba gusukurwa imbere byibuze rimwe mu mwaka. Amatara yose, ibishyushya byose bigenzurwa kugira ngo harebwe niba bikora neza. Bitabaye ibyo, ugomba gufata ingamba zo kubungabunga. Imiyoboro yose y'amashanyarazi n'insinga zo gutwaramo igenzurwa byibuze rimwe mu mwaka.

- Relays zose, alarm, na control switches hamwe na circuits zazo, muri R&C (Control Panel and Relays) na RTCC (Remote Tap Change Control Panel), zigomba gusukurwa hakoreshejwe isuku ikwiye.

- Imifuka ya OTI, WTI (ikimenyetso cy'ubushyuhe bw'amavuta n'ikimenyetso cy'ubushyuhe bwa coil) ku gipfundikizo cyo hejuru cya transformateur igomba kugenzurwa, kandi niba amavuta akenewe.

- Imikorere ikwiye y'igikoresho cyo kurekura umuvuduko n'uburyo bwo gusimbuza bwa Buchholz bigomba kugenzurwa buri mwaka. Kubwibyo, uburyo bwo gusimbuza n'uburyo bwo gusimbuza bw'ibikoresho byavuzwe haruguru bigabanuka n'agace gato k'insinga kandi bikareba niba uburyo bwo gusimbuza bw'ibikoresho bifitanye isano muri panelo igenzura kure bukora neza.

- Ubudahangarwa bw'ubushyuhe bwa transformer n'ubunini bwa polarity bigomba kugenzurwa hakoreshejwe icyuma gikoresha bateri ya 5 kV.

- Agaciro k'ubudahangarwa bw'ubutaka hamwe na rizer bigomba gupimwa buri mwaka hakoreshejwe icyuma gipima ubudahangarwa bw'ubutaka.

- Isesengura rya DGA cyangwa gazi yashongeshejwe rya peteroli rigomba gukorwa buri mwaka kuri transformateur za 132 kV, rimwe mu myaka 2 kuri transformateur ziri munsi ya 132 kV, mu gihe cy'imyaka ibiri kuri transformateur ziri kuri transformateur ya 132 kV.

Ingamba zigomba gufatwa rimwe mu myaka ibiri:

Gupima OTI na WTI bigomba gukorwa rimwe mu myaka ibiri.
Gupima imirasire ya transformer bigomba gukorwa rimwe mu myaka ibiri
5. Gusana transformer mu gihe cy'amezi atandatu
Transformateur yawe igomba kugeragezwa buri mezi atandatu kugira ngo irebe niba ifite IFT, DDA, flash point, ingano y'ibitaka, aside, ingano y'amazi, imbaraga za dielectric, ndetse n'ubudahangarwa bw'amavuta ya transformateur.

6. KubungabungaTransformateur y'ubu
Transformateur zikoreshwa ubu ni igice cy'ingenzi cy'ibikoresho byose byashyizwe muri sitasiyo y'amashanyarazi kugira ngo birinde kandi bipime amashanyarazi.
Ingufu zo gukingira ubushyuhe bw'icyuma CT bigomba kugenzurwa buri mwaka. Mu gihe cyo gupima ubukana bw'ubushyuhe, ni ngombwa kwibuka ko hari urwego rubiri rw'ubushyuhe mu byuma bihindura amashanyarazi. Urwego rw'ubushyuhe rwa CT y'ibanze ruri hejuru cyane, kuko rugomba kwihanganira voltage ya sisitemu. Ariko CT y'inyongera ifite urwego rwo hasi rw'ubushyuhe muri rusange rwa 1.1 kV. Kubwibyo, transformers z'inyongera kuva ku ntangiriro kugeza ku za kabiri n'iz'inyongera kuva ku butaka zipimirwa muri 2.5 cyangwa 5 kV. Ariko iyi volteji nini ntishobora gukoreshwa mu bipimo bya kabiri kuko urwego rw'ubushyuhe ruri hasi ukurikije imiterere y'ubukungu bw'igishushanyo. Kubwibyo, ubushyuhe bwa kabiri bupimirwa muri 500 V megger. Bityo, terminal y'ibanze ku butaka, terminal y'ibanze kugeza ku gice cyo gupima cya kabiri, n'igice cyo hejuru kugeza ku gice cyo gukingira cya kabiri bipimirwa muri 2.5 cyangwa 5 kV meggers.
Gusuzuma ikirere hifashishijwe ikoranabuhanga rya "Thermo vision" ku bice by'ibanze n'inyuma bya CT ikora bigomba gukorwa nibura rimwe mu mwaka. Ubu buryo bushobora gukorwa hifashishijwe Kamera yo Gusuzuma Ubushyuhe ya Infrared.
Imiyoboro yose ya CT secondary mu gasanduku ka CT secondary n'agasanduku ka CT junction igomba kugenzurwa, gusukurwa, no gukomezwa buri mwaka kugira ngo hamenyekane inzira yoroshye yo kurwanya CT secondary. Nanone, menya neza ko agasanduku ka CT junction gasukuwe neza.

Ibicuruzwa bya MBT Transformer

7. Gutunganya buri mwakatransformateur y'amashanyarazitransfoma za voltage za s cyangwa capacitor
Igipfukisho cya porcelain kigomba gusukurwa n'imyenda ya pamba.
Iteraniro ry'icyuho cy'urumuri rizajya rigenzurwa buri mwaka. Kuraho igice cyimukanwa cy'icyuho cy'urumuri mu gihe cyo guteranya, sukura electrode ya braes ukoresheje sandpaper, hanyuma uyisubize mu mwanya wayo.
Ahantu ho guhagarara hakoreshejwe amashanyarazi menshi hagomba gusuzumwa buri mwaka mu gihe ikibazo kitakoreshejwe kuri PLCC.
Kamera zikoresha uburyo bwo kureba ubushyuhe mu kugenzura ahantu hose hashyushye mu miyoboro ya capacitor kugira ngo harebwe ko ibikorwa byo gukosora ari abahanga.
Agasanduku k’aho PT ihurira kagizwe n’aho PT ihurira hapimwe ku butaka rimwe mu mwaka kugira ngo harebwe ko gafashe neza. Byongeye kandi, agasanduku k’aho PT ihurira kagomba kandi gusukurwa neza rimwe mu mwaka.
Imiterere y'ingingo zose za gasket nayo igomba gusuzumwa neza no gusimburwa niba habonetse udupfundikizo twangiritse.
