1.1 Tlhaloso ea Morero

2000 kVA tse tharo phase pad mounted transformer e ile ea isoa USA ka 2025. Matla a lekantsoeng a transformer ke 2000 kVA le KNAN cooling. Matla a phahameng ke 12.47GrdY/7.2 kV e nang le ± 2 * 2.5% tapping range (NLTC), motlakase o tlaase ke 0.48Y / 0.277 kV, ba thehile sehlopha sa vector sa YNyn0.

Joalo ka karolo ea bohlokoa marang-rang a sejoale-joale a kabo ea motlakase, pad mounted transformer e etselitsoe ho fana ka phetoho e tšepahalang ea motlakase le phepelo ea motlakase bakeng sa lits'ebetso tsa bolulo, tsa khoebo le tsa indasteri. Transformer ena e hlahelletse ka boqapi ba eona e baballang tikoloho le e bolokehileng, e nang le oli ea FR3 ea tlhaho ea ester insulation-e leng tharollo e ka nchafatsoang habonolo, e felisang likotsi tsa tikoloho tse amanang le oli ea setso ea liminerale. Oli ea FR3 ha e ithorise feela ka polokeho ea mollo e ikhethang (e nang le flash le lintlha tsa mollo habeli tsa oli ea minerale) empa hape e eketsa nako ea bophelo ba pampiri e kenang ka makhetlo a robeli, e netefatsa hore ts'ebetso ea nako e telele-e tsitsisa. E tsamaellana le litekanyetso tse tiileng tsa matla a matla a DOE, e fokotsa tahlehelo ea matla le ho fokotsa litšenyehelo tsa ts'ebetso haholo. E na le-mohatlalatsi o hahelletsoeng, e sireletsa hantle khahlano le ho phahama ha motlakase le ho fetella ha nakoana, ha static shield e kopaneng e ntlafatsa ts'ebetso ea ho koala le ho fokotsa likotsi tse itseng tsa ho tsoa. The side{10}lebokose la gauge e phahamisitsoeng le fana ka tlhahlobo e bonolo ea nako{11}}ea maemo a bohlokoa a ts'ebetso, ho netefatsa tlhokomelo ka nako le ho lemoha liphoso. E qetiloe ka{13}}pente e soeufalitsoeng (RAL 9003) e phofshoana, transformer e fana ka tšireletso e ntle ea boemo ba leholimo le ts'ireletso ea kutu, e etsa hore e tšoanelehe libakeng tse fapaneng tsa kantle. Transformer ena ea pad mounted ke khetho e nepahetseng bakeng sa basebelisi ba etelletsang pele ho boloka tikoloho, polokeho ea ts'ebetso, le ho ts'epahala ha nako e telele{16}.

02 Tlhahiso

2.1 HV Neutral (H0)

Sebaka se phahameng{{0}tlase sa "voltage neutral point" sa transfoma ena e phahamisitsoeng se hlahisoa e le H0 bushing e arohaneng, moralo o entsoeng ka boomo o nolofatsang{2}}ts'ebetso le tlhokomelo ea sebaka sa marang-rang, le ho ntlafatsa ts'ireletseho ea ts'ebetso. Tokisetso ena e lumella hore ho be le taolo e nepahetseng holim'a monyetla oa ho se nke lehlakore, ka katleho e hatella likotsi tse feteletseng, 'me e lumellana ka mokhoa o sa tsitsang litlhoko tse fapaneng tsa marang-rang a matla (joalo ka mekhoa ea TN, TT), e leng se etsang hore transformer e ikamahanye le mefuta e mengata ea kabo ea litoropo, serapa sa boikhathollo sa indasteri le lits'ebetso tsa meaho ea khoebo.

2.2 LV Neutral Bushing (X0)

Karolo e tlase{{0}ea "voltage neutral" ea "pad mounted" e entsoe ka lihlahla tse peli tse ikhethileng bakeng sa ts'ebetso e ikhethileng: sehlahla se le seng se holisa thebe e tsitsitseng ka ntle ho tanka, 'me e theiloe ka mokhoa o sireletsehileng ka har'a komporo ea LV, e fokotsang kotsi ea ho tsoa le ho ntlafatsa ts'ebetso ea mochini oa transfoma; bushing e 'ngoe e sebelisoa feela bakeng sa ho etella pele sebaka sa ho se nke lehlakore sa LV, se nolofalletsang tlhophiso ea khokahano ea ntlha e sa nke lehlakore ho fihlela litlhoko tsa motheo tsa litsamaiso tse fapaneng tsa kabo.
