Zogulitsa–Milandu Yomaliza

Mu 2024, tinapereka transformer ya 12 MVA ku Philippines. Transformer iyi ili ndi mphamvu yovomerezeka ya 12,000 KVA ndipo imagwira ntchito ngati transformer yotsika pang'onopang'ono, kusintha voltage yoyamba ya 66 KV kukhala voltage yachiwiri ya 33 KV. Timagwiritsa ntchito mkuwa popanga zinthu zozungulira chifukwa cha mphamvu yake yamagetsi yapamwamba, mphamvu ya kutentha, komanso kukana dzimbiri.
Chopangidwa ndi ukadaulo wamakono komanso zipangizo zapamwamba kwambiri, chosinthira mphamvu chathu cha 12 MVA chimapereka kudalirika komanso kulimba kwapadera.
Ku JZP, tikutsimikiza kuti transformer iliyonse yomwe timapereka imayesedwa bwino. Tikunyadira kuti takhala ndi mbiri yabwino kwambiri yopanda cholakwika kwa zaka zoposa khumi. Zosinthira Mphamvu Zapangidwa kuti zikwaniritse miyezo yokhwima ya IEC, ANSI, ndi zina zotsogola padziko lonse lapansi.
 
Kukula kwa Kupereka
Chogulitsa: Chosinthira Mphamvu Choviikidwa mu Mafuta
Mphamvu Yovomerezeka: Mpaka 500 MVA
Voltage Yoyamba: Mpaka 345 KV

Njira yozizira ya Transformer Yomizidwa ndi Mafuta Nthawi zambiri amagwiritsa ntchito mafuta a transformer ngati njira yoziziritsira. Mafuta awa amagwira ntchito ziwiri zazikulu: amagwira ntchito ngati chotetezera magetsi ndipo amathandiza kuchotsa kutentha komwe kumapangidwa mkati mwa transformer. Nazi njira zina zoziziritsira zomwe zimagwiritsidwa ntchito mu ma transformer omwe amamizidwa ndi mafuta:
1. Mafuta Achilengedwe Amlengalenga Wachilengedwe (ONAN)
● Kufotokozera:
Mu njira iyi, convection yachilengedwe imagwiritsidwa ntchito kufalitsa mafuta mkati mwa thanki ya transformer.
o Kutentha komwe kumapangidwa ndi ma windings a transformer kumatengedwa ndi mafuta, omwe kenako amakwera ndikusamutsa kutentha kupita ku makoma a thanki.
Kutenthako kumatulutsidwa mumlengalenga wozungulira kudzera mu convection yachilengedwe.

● Mapulogalamu:
o Yoyenera ma transformer ang'onoang'ono komwe kutentha komwe kumapangidwa sikupitirira muyeso.

● Kufotokozera:
Njira iyi ndi yofanana ndi ya ONAN, koma imaphatikizapo kuyendetsedwa kwa mpweya mokakamizidwa.
Mafani amagwiritsidwa ntchito kupumira mpweya pamwamba pa radiator ya transformer, zomwe zimapangitsa kuti njira yoziziritsira izigwira ntchito bwino.

● Mapulogalamu:
o Amagwiritsidwa ntchito mu ma transformer apakatikati pomwe kuziziritsa kwina kumafunika kupitirira kutsekeka kwa mpweya wachilengedwe.

● Kufotokozera:
Mu OFAF, mafuta ndi mpweya zimayendetsedwa pogwiritsa ntchito mapampu ndi mafani, motsatana.
o Mapampu amafuta amayendetsa mafuta kudzera mu transformer ndi ma radiator, pomwe mafani amakakamiza mpweya kudutsa ma radiator.

● Mapulogalamu:
o Yoyenera ma transformer akuluakulu komwe convection yachilengedwe sikokwanira kuziziritsa.

● Kufotokozera:
Njira iyi imagwiritsa ntchito madzi ngati njira yowonjezera yoziziritsira.
o Mafuta amayendetsedwa kudzera mu makina osinthira kutentha komwe madzi amaziziritsa mafuta.
Madziwo amaziziritsidwa kudzera mu makina enaake.

● Mapulogalamu:
Amagwiritsidwa ntchito m'ma transformer akuluakulu kapena malo oyikapo pomwe malo oziziritsira mpweya ndi ochepa ndipo pamafunika mphamvu zambiri.

● Kufotokozera:
Mofanana ndi OFAF, koma ndi mafuta oyenda molunjika kwambiri.
o Mafutawo amayendetsedwa kudzera m'njira zinazake kapena m'mitsempha kuti aziziziritsa bwino pamalo enaake otentha mkati mwa transformer.

● Mapulogalamu:
o Amagwiritsidwa ntchito mu ma transformer komwe kuziziritsa kolunjika kumafunika kuti azitha kugawa kutentha kosagwirizana.

● Kufotokozera:
Iyi ndi njira yoziziritsira yapamwamba kwambiri pomwe mafuta amayendetsedwa kuti ayende m'njira zinazake mkati mwa transformer, kuonetsetsa kuti kuziziritsa kolunjika.
o Kutentha kumasamutsidwira m'madzi kudzera mu zosinthira kutentha, ndi kukakamizidwa kuti kutentha kutulutsidwe bwino.

● Mapulogalamu:
o Yabwino kwambiri pa ma transformer akuluakulu kapena amphamvu kwambiri m'mafakitale kapena ntchito zina zomwe zingagwiritsidwe ntchito m'malo omwe kutentha kwabwino ndikofunikira kwambiri.

2. Mafuta Opangidwa ndi Mpweya Wachilengedwe (ONAF)
3. Kayendedwe ka Ndege Koyendetsedwa ndi Mafuta (OFAF)
4. Mafuta Okakamizidwa ndi Madzi (OFWF)
5. Air Forced Yoyendetsedwa ndi Mafuta (ODAF)
6. Madzi Oyendetsedwa ndi Mafuta (ODWF)
