CHOSINTHA CHOMIZIDWA NDI MAFUTA

Mafotokozedwe Akatundu

Kwa ma transformer oviikidwa mu mafuta a 1000kVA ndi kupitirira apo, zizindikiro zakunja za thermometer ziyenera kuyikidwa, kenako zizindikiro zakutali. Ma transformer oviikidwa mu mafuta a 800kVA ndi kupitirira apo ayenera kukhala ndi zotumizira mpweya ndi zipangizo zoteteza kupanikizika. Ma transformer oviikidwa mu mafuta a 800kVA akhozanso kukhala ndi zotumizira mpweya malinga ndi zofunikira izi komanso pokambirana ndi wopanga. Ma transformer ouma ayenera kuyikidwa ndi wopanga, zipangizo zoyezera kutentha, makamaka pa zoyika ma transformer a 630kVA.

Zogulitsa zimagawidwa malinga ndi kuchuluka kwa magawo, ndipo ma transformer a gawo limodzi amatha kugawidwa m'magulu atatu a ma transformer ndi ma transformer a gawo limodzi. Mu dongosolo lamagetsi la magawo atatu, kugwiritsa ntchito kwa ma transformer a magawo atatu kungapangidwenso ndi magulu atatu a ma transformer a gawo limodzi pamene mikhalidwe yoyendera ndi yayikulu kwambiri ndipo imakhudzidwa ndi dongosolo lamagetsi la magawo atatu.

Gulu la Zamalonda

Malinga ndi kuchuluka kwa ma windings, imatha kugawidwa m'ma transformer awiri ndi ma transformer atatu. Transformer nthawi zambiri imakhala transformer iwiri, mwachitsanzo pali ma windings awiri pakati, imodzi ya primary ndi ina ya secondary. Transformer itatu Ma transformer akuluakulu (oposa 5600 kVA) amalumikiza mizere itatu yamagetsi yamagetsi osiyanasiyana. Muzochitika zapadera, ma windings ambiri amagwiritsidwanso ntchito.

Malinga ndi kapangidwe ka mawonekedwe a gulu, imatha kugawidwa m'magulu awiri: transformer yapakati pa chitsulo ndi chitsulo chosinthira. Poyerekeza ndi kuzungulira kwa ma transformer apakati pa chitsulo kuzungulira pakati; popeza mphepete mwa pakatikati pake pamakhala chitsulo chosinthira chozungulira. Koma awiriwa ndi osiyana pang'ono mu kapangidwe kake, ndipo palibe kusiyana kwakukulu mu mfundo. Ma transformer amphamvu ndi mitundu yonse yapakati.

Malinga ndi momwe zimakhalira zotenthetsera ndi kuziziritsa, zitha kugawidwa m'magulu awiri: ma transformer oviikidwa mu mafuta ndi ma transformer ouma. Kuti zinthu ziwonjezeke bwino komanso zoziziritsa, pakati pa transformer ndi ma windings amaviikidwa mu thanki yokhala ndi mafuta osinthira. Nthawi zina, monga nyali za pamsewu, nyali za migodi, ndi ma transformer ouma.

Kuphatikiza apo, pali ma transformer apadera osiyanasiyana. Mwachitsanzo, kuyesa ma transformer amagetsi amphamvu kwambiri, ma transformer a ng'anjo, ma transformer oweda ndi ma circuits a thyristor pogwiritsa ntchito ma transformer, poyesa ma transformer amagetsi amphamvu ndi ma transformer amagetsi amphamvu.
