1.1 Tlhaloso ea Morero
Transformer ena e romelloa Amerika ka 2024 'me e entsoe ho latela maemo a machaba a IEC 60076-1:2011. Ke 2 MVA e qoelisoang ka metsi e nang le motlakase o phahameng / o tlase oa 11 kV / 0.433 kV le sehlopha sa li-vector Dyn11, se netefatsang kabo e tšepahalang ea matla a indasteri le ho tsamaisana hantle ha mekhahlelo pakeng tsa mahlakore a phahameng le a tlaase.
Transformer ena e etselitsoe setsi sa ho lokisa oli se nchafalitsoeng, se sebetsanang le oli ea litšila. E fana ka phepelo ea motlakase e tsitsitseng le e tšepahalang bakeng sa lisebelisoa tse tsoelang pele tsa indasteri joalo ka lipompo, liheater le li-compressor. Ka matla a 2 MVA le NLTC ± 2 × 2.5% tokiso ea voltage, e netefatsa hore motlakase o tsoa o tsitsitse le tlas'a meroalo e feto-fetohang.
Taba ea pele, sesebelisoa sa ho tsamaisa motlakase se ka fana ka lisebelisoa tsa-mohato o le mong le{1}}mohato o le mong oa boraro. Khokahano ea Dyn11 e fana ka-mohato oa bone-mohato oa boraro o tsoang. Mehato e le 'ngoe-e sebetsa ntle le ho baka ho se leka-lekane ha motlakase. Mechine e meraro{9}}e fumana matla a lekaneng hantle.
Taba ea bobeli, ho hlophisoa ha semela ho hloka matla a holimo a hajoale le likhokahano tsa cable tse tenyetsehang. Moralo oa rona o kenyelletsa-lebokoso la lithapo tsa motlakase tse phahameng tse khonang ho kenya 16×1C 630 mm² XLPE/PVC lithapo tsa koporo le -libaka tsa koporo tse tlase bakeng sa likhokahano tsa makala, tse nolofalletsang ho kengoa ka kotloloho le katoloso e tlang.
Qetellong, ts'ebetso ea indasteri e hloka pholiso e sebetsang hantle le tahlehelo e tlase ea matla. Ho tsidifala ha ONAN ya transformer, copper windings, le mokedikedi wa metsi di netefatsa tshebetso e tshepehang kahara mocheso o itseng wa -25 degrees to 40 degrees . Ka tahlehelo e se nang mojaro ea 1.94 kW, tahlehelo ea mojaro ea 18.3 kW, le impedance ea 5%, transformer e fihlela tekano ea ts'ebetso, polokeho le ts'ebetso ea mocheso e loketseng ts'ebetso e tsoelang pele ea indasteri.
