01 Kakaretso

1.1 Semelo sa Morero

Likarolo tse peli tsa 80/50MVATransformer ea matlali rometsoe Afrika Boroa ka Phupu, 2024. Matla a lekantsoeng ke 50 MVA ka mokhoa oa ho pholisa oa ONAN. Matla a fihla ho 80MVA ha e le ONAF. Matla ke 132 ho 33 kV, 132 kV primary, 33 kV secondary. Li-transformer tse peli li sebelisoa liteisheneng tsa motlakase tsa photovoltaic Afrika Boroa.

Thempereichara ea sebaka seo ho kengoang motlakase ho sona ke -5 degrees C ho isa ho +45℃C, tekanyo ea tšilafalo ea tikoloho e matla, 'me mongobo o phahameng ke 85%. Sena se hloka hore lebokose la transformer le khone ho ikamahanya le maemo a fapaneng a thata. Tse pelili-transformer tsa matla a maharengre na le lebokoso le phahameng-le nang le matla, bokaholimo ba lebokose le amohela-moralo o thibelang kutu le kalafo e khethehileng ea pente ea spray, botenya ba pente bo kaholimo ho 125mm, bo ka thibelang khoholeho ea lehlabathe le lintho tse ling tse kotsi. Radiator ea chip ea transformer ena e nka mokhoa o khethehileng oa ho futhumatsa dip galvanizing. Ho feta moo, mokotla o phahameng le o tlase oa khatello e nang le borakete ea sebono sa galvanized. Lipotoloho tsohle tsa taolo ea transformer li hloka ho sireletsoa, ​​'me sebaka se phahameng sa motlakase se sa nke lehlakore se hloka ho theoa. Mosamo o mong le o mong oa oli o tla le mosamo oa oli ea capsule le mokelli o lutlang.

2.1 Ntlha ea bohlokoa

Karolo e 'ngoe le e 'ngoe ea mantlha e tšehetsa li-winding tsa transfoma ea matla, ka boholo le sebopeho sa maoto le matsoho a entsoeng ho ipapisitse le matla a lekantsoeng (80MVA) le boemo ba voltage. Likarolo tse tšekaletseng tsa mokokotlo, tse bitsoang joko, li hokahanya maoto le matsoho a mararo holimo le tlase, li etsa potoloho e koetsoeng ea makenete. Bohareng bo entsoe ka -ho khona ho kenella ha metsi, ho fokola-tahlehelo e batang-lithollo tse kolokisitsoeng-ka lishiti tsa tšepe tsa silicon ho fokotsa tahlehelo ea mantlha (ho kenyeletsoa hysteresis le tahlehelo ea hona joale ea eddy). Maoto a mantlha le joko li etsa potoloho e koetsoeng ea makenete. Magnetic flux e phatlalla le maoto le matsoho a mararo, 'me phallo ea mohato ka mong e feta jokong ebe e hokahana le mekhahlelo e meng e 'meli, ho netefatsa hore{9}}mokhahlelo o leka-lekaneng oa mekhahlelo e meraro.

2.2 Ho tsubella

Palo ea ho tjeka, ho feta-karolo ea sekontiri, le sebaka sa sebaka ka seng li ntlafatsoa ho ipapisitsoe le boemo ba motlakase oa transformer, matla a motlakase, le litlhoko tsa hajoale. Kaha matsoelintsoeke a ntse a tsoela pele, matla a khoheli a ajoa ka mokhoa o ts'oanang ho pholletsa le mapheo, ho fokotsa litlamorao tsa leakage flux. Ho chencha ka mokhoa o lekanang ho netefatsa hore motlakase o tsamaea hantle, o fokotsa-khatello ea motlakase le khatello ea motlakase. Tlhophiso e tiileng ea likarolo tse matsoelintsoeke e etsa hore potoloho ea makenete e koalehe haholoanyane, e fokotse ts'ebetso ea ho lutla le ho ntlafatsa ts'ebetso ea transformer.

2.3 Tanka

1. Ha botenya ba letlapa la tšepe le haufi le lebokose le le ka tlaase ho 12mm, ho sebelisoa thepa ea tšepe e sephara ea Q235, 'me mochine oa ho phunya o sebelisetsoa ho khaola hlobo. Ha botenya ba poleiti ea tšepe haufi le lebokose ke> 12mm, ho sebelisoa poleiti ea tšepe ea thepa ea Q235, 'me thepa e khaoloa ke mochine oa ho itšeha oa CNC oa mollo / plasma.

2. Botlaaseng ba tanka ea transformer e entsoe ka tšepe ea tšepe ea Q235. Ha botenya ba poleiti ea tšepe bo le tlase ho 14mm, mochine oa ho itšeha o sebelisoa. Ha botenya ba poleiti ea tšepe ke> 16mm, sebelisa mochine oa ho itšeha oa CNC ho khaola thepa.

Ka mor'a hore lebota la lebokose le bokelloe, phekolo ea lik'hemik'hale e etsoa ho latela mokhoa oa OFL.140.5060 pickling phosphating.

3. Sekoahelo sa tanka ea transformer se entsoe ka tšepe ea tšepe ea Q235. Ha botenya ba poleiti ea tšepe bo le tlase ho 14mm, mochine oa ho itšeha o sebelisoa. Ha botenya ba poleiti ea tšepe ke> 16mm, sebelisa mochine oa ho itšeha oa CNC ho khaola thepa.

Melemo ea ho futhumatsa dip galvanizing

Bakeng sa li-radiator tsa chip bakeng sa 80 MVA ea ho theola motlakase oa motlakase, mokhoa oa ho futhumatsa oa dip dip o fana ka melemo e mengata ea bohlokoa:

• Ho hanyetsa ha kutu: Lera le chesang la dip galvanizing le ka thibela ka katleho khoholeho ea moea le metsi holim'a tšepe le ho ntlafatsa bophelo ba tšebeletso ea radiator, haholo-holo libakeng tse mongobo kapa tse senyang.

• Ho hanyetsa ho apara: Lera le nang le galvanized le ka boela la eketsa ho hanyetsa ha mocheso oa mocheso, ho etsa hore ho se ke ha e-ba bonolo ho senyeha ha ho ferekana 'meleng kapa ho thulana.

• Tlhokomelo e bonolo: Li-radiator tsa galvanized tsa dip dip di hloka hoo e ka bang ha ho na tlhokomelo e eketsehileng, ho fokotsa tlhokahalo le litšenyehelo tsa tlhokomelo hamorao.

• Ntlafatsa bokgoni ba ho qhala mocheso: Le hoja sekontiri se chesang haholo se le molemong oa ho thibela kutu, ka tsela e sa tobang se ka ntlafatsa bokhoni ba ho felisa mocheso ka ho boloka bokaholimo ba radiator bo le boreleli 'me bo se na mafome{0}.
