Ha ho etsoa li-transformer tsa kabo, ke ofe ho molemo ho sebelisa li-winding tsa terata tsa koporo kapa li-wireless wire windings, ‘me melemo le melemo ea e’ ngoe le e ‘ngoe ke efe?
Potoloho e ka hare ea transformer e entsoe haholo-holo ka li-winding (tseo hape li bitsoang li-coils), tse amanang ka ho toba le marang-rang a matla a ka ntle ‘me ke karolo ea mantlha ea transformer. Potoloho e ka hare ea transformer hangata e entsoe ka mapheo a terata. Lithapo tsa koporo le aluminium likhoele li arotsoe ka lithapo tse chitja, lithapo tse bataletseng (hape li arotsoe ka mehala e le ‘ngoe, lithapo tse kopantsoeng le lithapo tse fetisitsoeng), li-conductors tsa foil, joalo-joalo ho ea ka sebopeho sa lithapo tsa lithapo. Lithapo li koahetsoe ka mefuta e fapaneng ea li-insulation. layer, mme qetellong ba thehe khoele ka kakaretso. Ka hona, lisebelisoa tse ka sehloohong tsa mokhanni oa potoloho ea transformer li Koporo le aluminium.

3.2 Papiso ea ts’ebetso ea lithapo tsa koporo le aluminium ho li-winding tsa transformer
Phapang lipakeng tsa li-transformer tsa koporo le aluminium e boetse e khethoa ke phapang ea thepa, e bonts’ang likarolo tse latelang:
1) Ho hanyetsa ha mokhanni oa koporo ke hoo e ka bang 60% feela ea mokhanni oa aluminium. E le ho finyella litlhoko tse tšoanang tsa tahlehelo le ho phahama ha mocheso, sebaka sa sefapano sa aluminium conductor se lokelang ho sebelisoa se feta 60% se seholo ho feta sa mokhanni oa koporo, kahoo matla a tšoanang le litekanyetso tse tšoanang Tlas’a maemo a tloaelehileng, aluminium conductor transformer hangata e kholo ho feta mochine oa motlakase oa koporo, empa ka nako ena sebaka sa ho senya mocheso sa transformer se boetse se eketseha, kahoo mocheso oa eona o nyolohela ho oli o tlaase;
2) Boima ba aluminium ke hoo e ka bang 30% feela ea koporo, kahoo mochine oa aluminium conductor distribution transformer o bobebe ho feta mochine oa ho tsamaisa mochine oa koporo;
3) Sebaka sa ho qhibiliha sa li-conductors tsa aluminium se tlase haholo ho feta sa li-conductor tsa koporo, ka hona moeli oa eona oa ho phahama ha mocheso ka nako e khutšoanyane ke 250 ° C, e leng e ka tlaase ho ea li-conductor tsa koporo ka 350 ° C, ka hona, sebopeho sa eona ke XNUMX ° C. e tlase ho feta ea li-conductor tsa koporo, ‘me sebaka sa marang-rang sa lithapo tsa motlakase se seholoanyane. E kholo, kahoo molumo o boetse o moholo ho feta mochine oa motlakase oa koporo;
4) Boima ba mokhanni oa aluminium bo tlaase, kahoo li-burrs tsa eona li bonolo ho li felisa, kahoo ka mor’a hore transformer e etsoe, monyetla oa hore ho be le li-inter-turn kapa inter-layer short circuit e bakoang ke burrs e fokotsehile;
5) Ka lebaka la matla a tlaase le a ho hatella le matla a fokolang a mochine oa aluminium conductor, matla a nakoana a aluminium conductor transformer ha a tšoane le a koporo ea koporo ea koporo. Ha ho baloa botsitso bo matla, khatello ea mokhanni oa aluminium e lokela ho ba tlase ho 450kg / cm2, ha mochine oa koporo Moeli oa khatello ea mokhanni ke 1600kg / cm2, ‘me matla a ho jara a ntlafatsoa haholo;
6) Ts’ebetso ea ho tjheseletsa pakeng tsa mokhanni oa aluminium le mokhanni oa koporo e futsanehile, ‘me boleng ba ho tjheseletsa ha lenonyeletso ha bo bonolo ho tiisa, bo amang ho tšepahala ha mokhanni oa aluminium ho isa tekanyong e itseng.
7) Mocheso o khethehileng oa mokhanni oa aluminium ke 239% oa mokhanni oa koporo, empa ha ho nahanoa ka phapang pakeng tsa boima ba motlakase le moralo oa motlakase oa bobeli, phapang ea sebele pakeng tsa nako ea mocheso ea nako ea bobeli ha e kholo hakaalo. joalo ka phapang e khethehileng ea mocheso. Bokhoni ba nako e khuts’oane bo fetelletseng ba li-transformer tsa mofuta o omileng ha bo na phello e nyane.
