1. Injongo kunye neefom zeisitshintshiukugcinwa
a.Injongo yogcino lwesiguquli
Eyona njongo iphambili yogcino lwe-transformer kukuqinisekisa ukuba i-transformer kunye nezincedisi zangaphakathi nangaphandle amacandelozigcinwa zikwimeko entle, “ziyilungele injongo” kwaye zinokusebenza ngokukhuselekileyo nangaliphi na ixesha.Okubaluleke ngokulinganayo kukugcina irekhodi yembali yemeko ye-transformer.
b.Iifom zokulungisa i-transformer
Abaguquli bamandla badinga imisebenzi eyahlukeneyo yokugcinwa kwesiqhelo, kubandakanywa ukulinganisa kunye nokuvavanya iiparitha ezahlukeneyo ze-transformer.Kukho iindlela ezimbini eziphambili zokugcinwa kwe-transformer.Senza iqela elinye ngamaxesha athile (elibizwa ngokuba lulondolozo lothintelo) kwaye elesibini ngokwesiseko esikhethekileyo (okt, xa sifunwa).
2. Itshekhi yeNyanga yePeriodic Transformer Maintenance
– Inqanaba leoli kwi-oyile cap kufuneka lihlolwe inyanga nenyanga ukuze lingaweli ngaphantsi komda omiselweyo, kwaye ngaloo ndlela umonakalo obangelwayo ugwenywe.
- Gcina imingxuma yokuphefumla kwityhubhu yokuphefumla yejeli yesilica icocekile ukuqinisekisa ukusebenza ngokufanelekileyo kokuphefumla.
- Ukuba wakhoisiguquli samandlainamahlahla azalise ioli, qiniseka ukuba ioli izaliswe ngokuchanekileyo.
Ukuba kuyimfuneko, ioli iya kuzaliswa kwi-bushing ukuya kwinqanaba elichanekileyo.Ukuzaliswa kweoli kwenziwa kwimeko yokuvala.
3. UkuLondolozwa kweMihla yonke kunye nokuHlola
– Funda i-MOG (i-Magnetic Oil Meter) yetanki enkulu kunye netanki yokugcina.
- Umbala wejeli ye-silica emphefumlweni.
- Ukuvuza kweoli kuyo nayiphi na indawo ye-transformer.
Kwimeko yezinga leoli elinganelisekanga kwi-MOG, ioli kufuneka izaliswe kwi-transformer, kwaye itanki yonke ye-transformer kufuneka ihlolwe ukuvuza kweoli.Ukuba kufunyenwe ukuvuza kweoyile, thatha amanyathelo ayimfuneko ukuvala ukuvuza.Ukuba ijeli ye-silica iba pink kancinci, kufuneka itshintshwe.
4. Ishedyuli esisiseko yokulondolozwa kwenguqu yonyaka
- Umsebenzi ozenzekelayo, okude, kunye nencwadana yendlela yokupholisa ithetha ukuba iimpompo zeoli, abalandeli bomoya, kunye nezinye izixhobo zijoyina inkqubo yokupholisa i-transformer kunye nesiphaluka sokulawula.Ziya kuvavanywa kwithuba lonyaka omnye.Kwimeko yokungasebenzi kakuhle, phanda isiphaluka solawulo kunye nesimo somzimba wempompo kunye nefeni.
- Zonke izihlahla ze-transformer kufuneka zicocwe ngelaphu elithambileyo lomqhaphu ngonyaka.Ngexesha lokucocwa kwe-bushing kufuneka ihlolwe iintanda.
- Ubume be-oyile ye-OLTC iya kujongwa rhoqo ngonyaka.Ngoko ke, isampuli yeoli iya kuthathwa kwi-valve ye-drain ye-diverging tank, kwaye le sampuli yeoli eqokelelweyo iya kuvavanywa amandla e-dielectric (BDV) kunye nomswakama (PPM).Ukuba i-BDV iphantsi, kwaye iPPM yomswakama iphezulu kunexabiso elicetyiswayo, ioli ngaphakathi kwe-OLTC kufuneka ithathelwe indawo okanye ihluzwe.
- Ukuhlolwa koomatshini beBuchholziireyidikufuneka yenziwe minyaka le.
- Zonke izitya kufuneka zicocwe ngaphakathi kanye ngonyaka.Zonke izibane, izifudumezi zasesithubeni ziyajongwa ukuba zisebenza kakuhle na.Ukuba akunjalo, kufuneka uthathe inyathelo lesondlo.Lonke uqhagamshelo lwetheminali yolawulo kunye ne-relay wiring kufuneka zitshekishwe ziqiniswe kanye ngonyaka.
- Zonke ii-relays, i-alamu, kunye nokutshintsha kokulawula kunye neesekethe zabo, kwi-R & C (iPhaneli yoLawulo kunye neeRelays) kunye ne-RTCC (i-Remote Tap Change Control Panel) iipaneli, kufuneka zicocwe ngokucoca ngokufanelekileyo.
- Iipokotho ze-OTI, i-WTI (isalathisi sobushushu be-oyile kunye nesalathisi sobushushu be-coil) kwisigubungelo esiphezulu se-transformer ukuba sihlolwe, kwaye ukuba ioli iyafuneka.
- Umsebenzi ofanelekileyo weDivaysi yoKhupho loxinzelelo kunye ne-Buchholz relay kufuneka ihlolwe ngonyaka.Ke ngoko, izixhobo ezingasentla 'abafowunelwa bohambo kunye nabafowunelwa be-alam bafinyezwa ngeqhekeza elincinci locingo kwaye bajonge ukuba iireyiyidi ezinxulumeneyo kwiphaneli yolawulo olukude zisebenza ngokuchanekileyo.
- I-insulation resistance resistance and polarity index iya kujongwa nge-megger esebenza ngebhetri ye-5 kV.
- Ixabiso loxhathiso loqhagamshelo lomhlaba kunye nerizer kufuneka zilinganiswe ngonyaka nge-clamp kwimitha yokumelana nomhlaba.
- I-DGA okanye uhlalutyo lwerhasi enyibilikileyo ye-oyile ye-transformer kufuneka lwenziwe ngonyaka kwi-132 kV transformer, kanye kwiminyaka emi-2 kwiziguquli ezingaphantsi kwe-132 kV, iminyaka emibini kwiziguquli kwi-132 kV transformer.
Inyathelo eliza kwenziwa kanye kwiminyaka emibini:
Ulungelelwaniso lwe-OTI kunye ne-WTI kufuneka lwenziwe kube kanye kwiminyaka emibini.
Tan & delta;Umlinganiselo we-transformer bushings uya kwenziwa kube kanye kwiminyaka emibini
5. Ulondolozo lwe-transformer kwisiqingatha sonyaka
I-transformer yakho yamandla idinga ukuvavanywa rhoqo kwiinyanga ezintandathu kwi-IFT, i-DDA, i-flash point, umxholo we-sludge, i-acidity, umxholo wamanzi, amandla e-dielectric, kunye nokumelana ne-oyile ye-transformer.
6. Ukugcinwa kweIsiguquli sangoku
Iziguquli zangoku ziyinxalenye ebalulekileyo yaso nasiphi na isixhobo esifakelwe kwisikhululo sogutyulo lwamandla ukukhusela nokulinganisa umbane.
Amandla e-insulation of the CT kufuneka ijongwe ngonyaka.Kwinkqubo yokulinganisa ukuchasana kwe-insulation, kufuneka kukhunjulwe ukuba kukho amanqanaba amabini e-insulation kwi-transformers yangoku.Inqanaba lokufakelwa kwe-CT ephambili liphezulu, njengoko kufuneka limelane nombane wenkqubo.Kodwa i-CT's yesibini inezinga elisezantsi lokugqunyelelwa ngokubanzi kwe-1.1 kV.Ngoko ke, iprayimari ukuya kweyesibini kunye neprayimari emhlabeni wabaguquli bangoku balinganiswa kwi-2.5 okanye i-5 kV meggers.Kodwa le megger yombane iphezulu ayinakusetyenziselwa imilinganiselo yesibini kuba inqanaba lokugquma lisezantsi ngokwembono yezoqoqosho kuyilo.Ngoko ke, i-insulation yesibini ilinganiswa kwi-500 V megger.Ngaloo ndlela, i-terminal ephambili emhlabeni, i-terminal ephambili ukuya kwinqanaba lesibini lokulinganisa, kunye ne-terminal ephambili kwi-terminal yesibini yokukhusela ilinganiswa kwi-2.5 okanye i-5 kV meggers.
Ukukhangela umbono weThermo kwiitheminali eziphambili kunye nedome ephezulu yeCT ephilayo kufuneka yenziwe kanye ngonyaka.Esi skena sinokwenziwa ngoncedo lwe-Infrared Thermal Surveillance Camera.
Zonke ii-CT ze-secondary connections kwi-CT ye-secondary box kunye ne-CT junction box kufuneka zihlolwe, zicocwe, kwaye ziqiniswe minyaka le ukuze kuqinisekiswe indlela ephantsi yokumelana ne-CT yesibini.Kwakhona, qiniseka ukuba ibhokisi ye-CT junction icocwe ngokuchanekileyo.
Iimveliso ze-MBT Transformer
7. Ulondolozo lonyaka lwei-voltage transformers okanye i-capacitor voltage transformers
Isigqubuthelo se-porcelain kufuneka sicocwe ngempahla yekotoni.
Indibano ye-spark gap iya kujongwa rhoqo ngonyaka.Susa indawo ehambayo ye-spark gap xa udibanisa, coca i-electrode ye-braes nge-sandpaper, kwaye uyilungise kwakhona endaweni.
Indawo esekelwe kuyo i-high-frequency grounding kufuneka ijongwe ngokubonakalayo ngonyaka ukuba umcimbi awusetyenziswanga kwi-PLCC.
Iikhamera zombono we-Thermal zisetyenziselwa ukukhangela naziphi na iindawo ezishushu kwii-stacks ze-capacitor ukuqinisekisa isenzo sokulungiswa kweengcali.
Uqhagamshelo lwetheminali Ibhokisi yokuhlangana ye-PT iqulathe uqhagamshelo lomhlaba oluvavanyelwe ukuqina kanye ngonyaka.Ngaphandle koko, ibhokisi ye-PT yokuhlangana kufuneka kwakhona icocwe kakuhle kanye ngonyaka.
Imeko yazo zonke ii-gasket joints kufuneka kwakhona zihlolwe ngokubonakalayo kwaye zitshintshwe ukuba izitywina ezonakalisiweyo zifunyenwe.
