1. Ujeedada iyo qaababkatransformerdayactirid
a.Ujeedada dayactirka transformerka
Ujeedada ugu muhiimsan ee dayactirka beddelka waa in la hubiyo in transformer-ka iyo agabka 'gudaha iyo dibaddaba' qaybahalagu hayo xaalad wanaagsan, "ku habboon ujeeddada" waxayna u shaqayn karaan si badbaado leh wakhti kasta.Si la mid ah muhiim waa in la ilaaliyo diiwaanka taariikhiga ah ee xaaladda transformerka.
b.Foomamka dayactirka beddelka
Transformers korontadu waxay u baahan yihiin hawlo kala duwan oo dayactir joogto ah, oo ay ku jiraan cabbiraadda iyo tijaabinta cabbirrada beddelka ee kala duwan.Waxaa jira laba nooc oo aasaasiga ah ee dayactirka transformerka.Waxaan sameynaa hal koox si xilliyo ah (loo yaqaan dayactirka kahortagga) iyo tan labaad si aan caadi ahayn (sida, dalab).
2. Hubinta Dayactirka Transformer-ka ee bilaha ah
– Heerka saliidda ee daboolka saliidda waa in bishiiba mar la eego si aanay uga hoos dhicin xad go’an, sidaas darteedna laga fogaado waxyeelada ay keento.
- Ku hay nadiifinta daloolada neefsiga ee tuubada neefsiga ee silica jel si aad u hubiso hawlgallada neefsashada ee habboon.
- Haddii aadkoronto-dhaliyewaxay leedahay duurka saliida buuxiya, hubi in saliidda si sax ah loo buuxiyay.
Haddii loo baahdo, saliidda waxaa lagu buuxin doonaa duurka ilaa heerka saxda ah.Buuxinta saliidda waxaa lagu sameeyaa xaalada xiritaanka.
3. Dayactirka iyo hubinta Aasaaska Maalinlaha ah
– Akhri MOG (Magnetic Oil Meter) ee haanta weyn iyo haanta kaydinta.
- Midabka jelka silica ee neefta.
- Saliiddu waxay ka soo daadataa meel kasta oo ka mid ah transformerka.
Haddii ay dhacdo in heerka saliidda MOG ku qanci waayo, waa in saliidda lagu shubaa transformer-ka, taangiga transformer-ka oo dhan waa in la hubiyaa in uu shidaalku soo daatay.Haddii la helo dalool saliid, qaado tallaabada lagama maarmaanka ah si aad u xirto daadinta.Haddii jelka silica uu noqdo wax yar casaan, waa in la beddelaa.
4. Jadwalka dayactirka beddelka sannadlaha aasaasiga ah
- Shaqada tooska ah, fogaanta, iyo gacanta ee nidaamka qaboojinta waxay ka dhigan tahay in bambooyinka saliidda, taageerayaasha hawada, iyo qalabyada kale ay ku biiraan nidaamka qaboojinta beddelka iyo wareegga xakamaynta.Waxaa la baari doonaa muddo hal sano ah.Haddii ay dhacdo cilad, baar wareegga xakamaynta iyo xaaladda jireed ee bamka iyo marawaxada.
- Dhammaan kaymaha transformer-yada waa in lagu nadiifiyaa maro jilicsan sannadkii.Inta lagu jiro nadiifinta baadiyaha waa in laga fiiriyaa dildilaaca.
- Heerka saliidda OLTC waa la eegi doonaa sanad walba.Sidaa darteed, saamiga saliidda waxaa laga soo qaadi doonaa tuubada biyaha ee haanta kala weecida, waxaana saamigan saliidda ah ee la soo ururiyay lagu tijaabin doonaa xoogga dielectric (BDV) iyo qoyaan (PPM).Haddii BDV yar yahay, oo PPM ee qoyaanku ka sarreeyo qiimaha lagu taliyey, saliidda gudaha OLTC waxay u baahan tahay in la beddelo ama la sifeeyo.
- Kormeerka makaanikada ee Buchholzrelaysin la fuliyo sanad walba.
- Dhammaan weelasha waa in laga nadiifiyaa gudaha ugu yaraan hal mar sannadkii.Dhammaan nalalka, kuleyliyeyaasha hawada waa la hubiyaa si loo arko inay si sax ah u shaqeynayaan.Haddii kale, waa inaad qaaddaa tallaabo dayactir ah.Dhammaan xidhidhka kontoroolka iyo fiilooyinka gudbinta si loo hubiyo in la adkeeyo ugu yaraan hal mar sannadkii.
-Dhammaan relays, alaarmiga, iyo furayaasha kontoroolka oo ay weheliyaan wareegyadooda, ee ku jira R&C (Guddiga Koontaroolada iyo Relays) iyo RTCC (Guddiga Koontaroolada Isbeddelka Tap Fog), waa in lagu nadiifiyaa walaxda nadiifinta saxda ah.
- Jeebabka OTI, WTI (tusaha heerkulka saliidda & tusaha heerkulka gariiradda) ee daboolka sare ee beddelka si loo hubiyo, iyo haddii saliidda loo baahan yahay.
- Shaqada saxda ah ee Qalabka Siideynta Cadaadiska iyo gudbinta Buchholz waa in la hubiyaa sanad walba.Sidaa darteed, aaladaha kor ku xusan ee xiriirada safarka iyo xiriirada alaarmiga waxaa lagu soo gaabiyay silig yar oo fiiri haddii relaysyada la xiriira guddiga kantaroolka fog ay si sax ah u shaqeynayaan.
-Transformer-ka caabbinta dahaarka iyo tusaha polarity waa in lagu hubiyo megger ku shaqeeya baytari 5kV ah.
- Qiimaha iska caabinta xiriirka dhulka iyo rizer waa in lagu cabbiraa sanad walba iyadoo lagu dhejiyo mitirka caabbinta dhulka.
-DGA ama falanqaynta gaaska kala diri ee saliidda transformer waa in lagu sameeyaa sanad walba 132kV Transformers, hal mar 2 sano ee Transformers ka hooseeya 132 kV, muddo laba sano ah Transformers on 132 kV Transformer.
Tallaabo la qaado labadii sanaba hal mar:
Qiyaasta OTI iyo WTI waa in la sameeyaa hal mar labadii sanaba mar.
Tan & delta;Cabbiraadda kaynta transformer-ka waa in sidoo kale la sameeyaa labadii sanaba hal mar
5. Dayactirka Transformer ee ku salaysan nuska sano
Korontadu waxay u baahan tahay in lixdii biloodba mar lagu tijaabiyo IFT, DDA, dhibic flash, waxa ku jira sludge, acidity, content water, power dielectric, and transformer oil caabbinta.
6. DayactirkaTransformer hadda
Transformer-yada hadda jira waa qayb muhiim ah oo ka mid ah qalab kasta oo lagu rakibay xarun koronto si loo ilaaliyo loona cabbiro korontada.
Xoogga dahaarka ee CT waa in la hubiyaa sanad walba.Habka lagu cabbirayo caabbinta dahaadhka, waa in la xasuusto in ay jiraan laba heer oo dahaadh ah oo ku jira transformers-yada hadda jira.Heerka dahaarka ee CT-ga aasaasiga ah waa mid aad u sarreeya, maadaama ay tahay inay u adkeyso tamarta nidaamka.Laakiin CT-ga sare waxa uu leeyahay heerka dahaarka hoose ee guud ahaan 1.1kV.Sidaa darteed, hoose ilaa sare iyo hoose ee dhulka ee transformers hadda waxaa lagu qiyaasaa 2.5 ama 5 kV meggers.Laakiin megger-gangan sare looma isticmaali karo cabbirada labaad maadaama heerka dahaarka uu aad uga hooseeyo aragtida dhaqaalaha naqshadeynta.Sidaa darteed, dahaarka sare waxaa lagu qiyaasaa 500 V megger.Haddaba, terminaalka hoose ee dhulka, kan ugu horreeya ee u dhexeeya xudunta cabbirka sare, iyo terminaalka hoose ee xudunta sare ee ilaalinta ayaa lagu qiyaasaa 2.5 ama 5 kV meggers.
Baadhitaanka aragga Thermo ee terminaalka aasaasiga ah iyo qubbad sare ee CT nool waa in la sameeyaa ugu yaraan hal mar sannadkii.Sawirkan waxa lagu samayn karaa iyadoo la kaashanayo kamarada ilaalinta kulaylka infrared.
Dhammaan xidhiidhada sare ee CT-ga ee ku jira sanduuqa labaad ee CT iyo sanduuqa isgoysyada CT waa in la hubiyaa, la nadiifiyaa, lana adkeeyaa sanad walba si loo hubiyo jidka ugu hooseeya ee suurtogalka ah ee iska caabinta CT-ga labaad.Sidoo kale, iska hubi in sanduuqa isgoyska CT si sax ah loo nadiifiyay.
Alaabta Transformer-ka MBT
7. dayactirka sanadlaha ah eetransformer danabs ama Transformers danab capacitor
Daboolka weelka waa in lagu nadiifiyaa dharka suufka ah.
Isku-xidhka farqiga dhimbiiluhu waa la eegi doonaa sannad kasta.Ka saar qaybta dhaqaaqi karta ee farqiga dhimbilaha marka la isku keeno, ku nadiifi korantada korantada warqad ciid, oo ku hagaaji meeshiisii.
Barta soo noqnoqda ee soo noqnoqota waa in muuqaal ahaan loo eego sanadkiiba mar haddii arintu aan loo isticmaalin PLCC.
Kaamirooyinka aragga kulaylka waxaa loo isticmaalaa in lagu hubiyo meel kasta oo kulul ee xirmooyinka capacitor-ka si loo xaqiijiyo ficil saxid xirfad leh.
Xidhiidhada terminal sanduuqa isgoyska PT wuxuu ka kooban yahay isku xirka dhulka ee lagu tijaabiyo cidhiidhiga sannadkii hal mar.Ka sokow, sanduuqa isgoysyada PT waa in sidoo kale si habboon loo nadiifiyaa sannadkii hal mar.
Xaaladda dhammaan kala-goysyada gaasaska waa in sidoo kale muuqaal ahaan loo fiiriyaa oo la beddelaa haddii la helo shaabadihii burburay.
