Isiphaluka sangaphakathi se-transformer ikakhulu siqulunqwe ngama-windings (ekwabizwa ngokuba yi-coils), edibaniswe ngokuthe ngqo kwigridi yamandla yangaphandle kwaye iyona nxalenye ephambili ye-transformer. Isiphaluka sangaphakathi se-transformer ngokuqhelekileyo senziwe nge-wire windings. Iingcingo zobhedu kunye ialuminiyam iingcingo zahlulwe zibe iingcingo ezingqukuva, iingcingo ezisicaba (kwaye zahlulwe zibe iingcingo enye, iingcingo ezidityanisiweyo kunye iingcingo transposed), iiconductor foil, njl ngokobume cross-icandelo iingcingo. Iingcingo zigqunywe ngeentlobo ezahlukeneyo zokugquma. umaleko, kwaye ekugqibeleni wenze ikhoyili iyonke. Ngoko ke, izinto eziphambili zomqhubi wesiphaluka se-transformer zi zobhedu kunye ne-aluminiyam.

3.1 Uthelekiso lweepropati ze zobhedu kunye nealuminium

Zomibini ithusi kunye ne-aluminium zizinto zetsimbi ezine-conductivity efanelekileyo yombane, kwaye zisetyenziswa ngokuqhelekileyo ii-conductors ukwenza iikhoyili ze-transformer. Umahluko kwiimpawu zomzimba uboniswa kolu luhlu lulandelayo:

3.2 Ukuthelekisa ukusebenza kweengcingo zobhedu kunye ne-aluminium kwi-windings ye-transformer

Umahluko phakathi kobhedu kunye ne-aluminiyam i-transformers nayo inqunywe ngumahluko wezinto eziphathekayo, ezibonakaliswa kule miba ilandelayo:

I-1) Ukuxhatshazwa komqhubi wobhedu kuphela malunga ne-60% yaloo mqhubi we-aluminium. Ukuze ufezekise ilahleko efanayo kunye neemfuno zokunyuka kweqondo lokushisa, indawo enqamlezileyo yomqhubi we-aluminium oza kusetyenziswa ingaphezulu kwe-60% enkulu kunomqhubi wobhedu, ngoko ke umthamo ofanayo kunye neeparitha ezifanayo phantsi kweemeko eziqhelekileyo, i-aluminium conductor transformer idla ngokuba nkulu kune-copper conductor transformer, kodwa ngeli xesha indawo yokutshatyalaliswa kobushushu ye-transformer iyanda, ngoko ukunyuka kwayo kwioli kuphantsi;

2) Ubuninzi be-aluminium bumalunga ne-30% kuphela yobhedu, ngoko ke i-aluminium conductor distribution transformer ilula kune-copper conductor distribution transformer;

3) Indawo yokunyibilika yabaqhubi be-aluminium iphantsi kakhulu kuneekhonduthi zobhedu, ngoko ke umda wokunyuka kweqondo lokushisa kwi-short-circuit current yi-250 ° C, ephantsi kunaleyo yabaqhubi be-copper kwi-350 ° C, ngoko ubuninzi bayo boyilo. ephantsi kunaleyo yabaqhubi bezobhedu, kunye nommandla we-cross-sectional of transformer wires mkhulu. Enkulu, ngoko ke umthamo ubuye mkhulu kune-copper conductor transformer;

4) Ubunzima bomqhubi we-aluminium buphantsi, ngoko ke i-surface burrs yayo ilula ukuphelisa, ngoko emva kokuba i-transformer yenziwe, amathuba okuba i-inter-turn okanye i-inter-layer short circuit ebangelwa yi-burrs iyancitshiswa;

I-5) Ngenxa yobunzima obuphantsi kunye namandla acinezelayo kunye namandla angalunganga omatshini we-aluminium conductor, umthamo we-short-circuit ye-aluminium conductor transformer ayilungile njengaleyo ye-copper conductor transformer. Xa ubala ukuzinza okuguquguqukayo, uxinzelelo lomqhubi we-aluminium kufuneka lube ngaphantsi kwe-450kg / cm2, ngelixa umqhubi wobhedu Umda woxinzelelo we-conductor ngu-1600kg / cm2, kwaye umthamo wokuthwala uphuculwe kakhulu;

6) Inkqubo ye-welding phakathi komqhubi we-aluminium kunye nomqhubi wobhedu ihlwempu, kwaye umgangatho we-welding we-joint akulula ukuqinisekiswa, ochaphazela ukuthembeka komqhubi we-aluminium ukuya kwinqanaba elithile.

I-7) Ubushushu obuthile bomqhubi we-aluminium yi-239% yomqhubi wobhedu, kodwa ngokuqwalasela umahluko phakathi koxinano kunye noyilo lombane wombane wesibini, umahluko wangempela phakathi kwexesha le-thermal le-thermal yezo zibini azikho mkhulu. njengomahluko othile wobushushu. Umthamo ogqithisiweyo wexesha elifutshane we-transformer-type-type unempembelelo encinci.
