1.1 Tlhaloso ea Morero

Ka 2025, moreki oa Amerika Leboea o ile a etsa odaro ea 1000/1220 kVA (22% ea base kVA)-pade ea mekhahlelo e meraro-lebokoso la motlakase la transformer le behoang. Transformer ena e etselitsoe marang-rang a mahareng a-ea khoebo, a liindasteri le a bolulo ho pholletsa le Amerika Leboea.

E na le Vector Group Dyn1, e nang le motlakase o phahameng ho 12,470DV, 95 BIL, le motlakase o tlase ho 480Y/277 V, 30 kV BIL. Ka litlhaloso tsena, transformer e fana ka phetoho ea matla e tšepahalang bakeng sa litlhoko tse fapaneng tsa kabo, ebang ke ho fepa meaho ea khoebo, meaho ea indasteri kapa libaka tsa bolulo.

Transformer e kopanya likarolo tse ngata tsa bohlokoa. Moralo oa Dead Front, motheo o ikemetseng, le ts'ireletso ea surge e matlafatsa polokeho bakeng sa ba sebetsang le lisebelisoa; mapheo a koporo a kopantsoeng le oli ea insulating ea FR3 biodegradable e kopana le litekanyetso tsa ts'ebetso ea DOE 2016, e fanang ka tahlehelo e tlase le ts'ebetso e tsitsitseng tlasa ts'ebetso e tsoelang pele. Oli ea FR3, e nang le lebone la eona le holimo, 'me e na le botsoalle ba tikoloho, hammoho le C5M corrosion e felletseng{6}}e thibelang ho bola, e tiisa ho tšoarella ha lisebelisoa tsa kantle.

Tlhokomelo e otlolohile. Thempereichara, boemo ba mokelikeli, le likhatello tsa khatello kaofela li na le mabitso a alamo, 'me ho kenyelletsoa ha Schrader Valve ho nolofatsa tlhokomelo le ts'ebeletso. Likarolo tsena li etsa hore transformer e tšoanelehe bakeng sa ts'ebetso e tšepahalang,{2}}ea nako e telele ho litlhophiso tse kang litsi tsa khoebo, lifeme tsa liindasteri tse bobebe, le meaho e meholoanyane ea bolulo.

2.4 C5M Tanka ea Mafura ea ho Koala

Tanka ea transfoma e entsoe ka tšepe e cheselitsoeng e bonolo (MS) e nang le C5-M corrosion-e thibang, e tiisang hore e tšoarella libakeng tse thata tsa kantle. Kaho ea tanka e tiisitsoeng, e cheselitsoeng e fokotsa ho kenella ha mongobo le tlhokomelo. Setsi se entsoeng se kenyelletsa lipehelo tsa ho hula, ho jara le ho roala, ka lihakisi tsa ho phahamisa bakeng sa ho ts'oaroa ka mokhoa o bolokehileng. Likarolo tse ling li kenyelletsa mokoti oa "20" o nang le senotlolo, ho nolofatsa tlhahlobo le ts'ebeletso ea kamehla, le letlapa la XO le sa nke lehlakore le nang le terapo e ka ntšoang bakeng sa mapheo a LV a hoketsoeng ke wye.

2.5 Lihlahla tsa Motlakase o Phahameng le o Tlaase

HV Side: Dead Front bushing, rated 15 kV, 200 A; e nang le Elbow Arrester ho fana ka tšireletso e tšepahalang ea ho buuoa.
LV Side: 1.2 kV, 3100 A, 6-hole epoxy resin bushing (tin-plated), e etselitsoeng matla a ho thibela kutu.

03 Lisebelisoa tsa Tšireletso

Schrader valve - valve bakeng sa sampole ea khase kapa taolo ea khatello

1 "filter & valve ea ho tlatsa - valve bakeng sa ho tlatsa oli le ho sefa

Khatello ea liphallelo valve 50 ssfm - valve ho lokolla khatello e feteletseng ka tanka

Khatello ea vacuum gauge e nang le likhokahano tsa alamo – VIAT,{0}boleng bo holimo{0}ho hlokomela tanka e nang le alamo.

Tekanyo ea boemo ba mokelikeli e nang le alamo e nang le boemo ba 25 ° c - sesupo sa boemo ba oli se nang le alamo

Daela mofuta oa thermometer o nang le mabitso a alamo - VIAT, tekanyo e nepahetseng ea mocheso e nang le mabitso a alamo bakeng sa ho lekola oli ea transformer.

Motheo o ikemetseng bakeng sa mantlha - khokahano ea motheo e inehetseng bakeng sa mantlha ea transformer
