Iitransformer zizinto ezibalulekileyo kwiinkqubo zamandla ombane, ezinoxanduva lokuguqula amanqanaba e-voltage ukuze kudluliselwe amandla ngokufanelekileyo. Ukwakhiwa kweetransformer kufuna ukuqwalaselwa ngononophelo kwezinto kunye neenkqubo ukuqinisekisa ukusebenza okusemgangathweni nokuthembekileyo. Eli nqaku liza kujonga iinkalo ezahlukeneyo ezibandakanyekayo ekuqondeni ukwakhiwa kweetransformer, ukusuka ekukhetheni izinto ezifanelekileyo ukuya ekuphunyezweni kweenkqubo zemveliso ezisebenzayo.

1. Ukubaluleka kwezinto zokwakha kwiTransformer Construction

Izixhobo ezisemgangathweni ophezulu zidlala indima ebalulekileyo ekusebenzeni nasekuhlaleni ixesha elide kwee-transformers. Izinto eziphambili ze-transformer ziquka i-core, i-windings, i-insulation, kunye nenkqubo yokupholisa. Ngayinye kwezi zinto ifuna izinto ezithile.

a) Izinto ezingundoqo: Iitransformer zihlala zisebenzisa ii-cores ezifakwe i-laminated ezenziwe ngeeshiti zentsimbi zombane ezibhityileyo nezikumgangatho ophezulu. La shiti anciphisa ukulahleka kwamandla okubangelwa yimisinga ye-eddy kunye ne-hysteresis, okuqinisekisa ukuhanjiswa kwamandla ngokufanelekileyo. Ukongeza, intsimbi yombane ejolise kwiinkozo inciphisa ukulahleka kwe-core ngakumbi, nto leyo enceda ukusebenza kakuhle kwetransformer.

b) Iiwindings: I-Copper kunye ne-aluminium zezona zikhethwa kakhulu kwiiwindings ze-transformer. I-Copper ibonakalisa ukuhanjiswa kombane okuphezulu, nto leyo eyenza ukuba ibe yeyona nto ikhethwayo kwii-transformers ezinamandla aphezulu. Nangona kunjalo, i-aluminium inexabiso eliphantsi kwaye ifanelekile kwii-applications zamandla aphantsi ukuya kwaphakathi.

c) Izinto Zokugquma: Ugquma lubalulekile ekuthinteleni ukuqhekeka kombane. Izinto zokugquma ezisetyenziswa rhoqo ziquka i-pressboard, i-Nomex, kunye ne-varnish. I-Pressboard isetyenziswa kakhulu ngenxa yeempawu zayo zombane nezoomatshini ezibalaseleyo. I-Nomex, iphepha le-aramid, inika uzinzo kubushushu obuphezulu kunye nokumelana nomlilo. I-varnish isetyenziselwa ukufunxa ii-windings, ukuzikhusela kumswakama kunye nokuphucula iimpawu zokugquma.

d) Izixhobo Zokupholisa: Ukupholisa ngokufanelekileyo kuyimfuneko ukugcina amaqondo obushushu afanelekileyo okusebenza kwiitransformer. Izixhobo zokupholisa, ezifana neoyile yetransformer okanye ii-esters zokwenziwa, zisusa ubushushu obuveliswa ngexesha lokusebenza. Ioyile yetransformer ineempawu ezintle zokuthintela ubushushu kunye nokuqhuba okuphezulu kobushushu. Nangona kunjalo, ii-esters zokwenziwa ziyathandwa ngenxa yokuba zinobuhlobo nokusingqongileyo kunye nokhuseleko oluphuculweyo lomlilo.

2. Iinkqubo zoMveliso zoKwakha iiTransformer

Ubuchule bokwakha i-transformer abubandakanyi nje ukukhetha izixhobo ezifanelekileyo kodwa kukwabandakanya nokusebenzisa iinkqubo zokuvelisa ezisebenzayo. Iinkqubo ezininzi ezibalulekileyo ziqinisekisa imveliso esemgangathweni ophezulu:

a) Ukwenziwa kweCore: I-core yintliziyo ye-transformer, enoxanduva lokungenisa i-electromagnetic. Ihlala yakhiwa ngokuhlanganisa amaphepha entsimbi afakwe i-laminated kunye. Amaphepha anqunyulwa nge-laser okanye abethelwe ngoomatshini ngokwemilinganiselo efunekayo. I-core emva koko ihlanganiswa kusetyenziswa iindlela zokucinezela, ukuwelda, okanye ukuncamathisela. Emva kokuhlanganiswa, i-core iyaxutywa ukuze kuncitshiswe uxinzelelo kwaye kuphuculwe iimpawu zemagnethi.

b) Ukwenziwa kweMigodi: Ii-transformer windings ziqulunqwe nge-coil yokuqala neyesibini. Ukwenziwa kweMigodi kubandakanya ukugoba ngononophelo ucingo lobhedu olugqunyiweyo okanye ucingo lwe-aluminium olujikeleze umbindi. Oomatshini abasebenzisa ikhompyutha baqinisekisa ukugoba okuchanekileyo, benciphisa ilahleko zombane. Ii-windings zifakwe i-varnish okanye i-resin ukuze kuphuculwe iimpawu zokugquma.

c) Ukuhlanganiswa kwe-Insulation: Izinto zokukhusela ziyakhethwa, zinqunyulwe, kwaye zidityaniswe ukuze zibonelele ngokhuseleko lombane phakathi kwee-windings kunye ne-core. Ukuhlanganiswa kwe-insulation ngokuchanekileyo kuthintela ukuqhekeka kombane kwaye kuqinisekisa ukusebenza okuthembekileyo. Iileya ze-pressboard, i-Nomex, kunye nezinto zokukhusela eziphathwe nge-varnish ziyabekwa kwaye zifakwe phakathi kwee-windings, zenze i-insulation.

d) Ukwakhiwa kweTanki: Iitanki zetransformer zigcina umbindi, iiwindings, kunye nenkqubo yokupholisa. Iitanki zihlala zakhiwa kusetyenziswa iipleyiti zentsimbi ezidityanisiweyo kunye. Izinto ezibalulekileyo, ezifana neebushings, ziyafakelwa, kwaye amanyathelo okuvala afanelekileyo ayasetyenziswa ukuthintela ukuvuza. Itanki ivavanywa amandla kunye nokuvuza, ukuqinisekisa ukuba iyahlangabezana nemigangatho yoshishino.

e) Uvavanyo kunye noQinisekiso loMgangatho: Ngaphambi kokuba iitransformer ziphume kwindawo yokuvelisa, zivavanyelwa ngokuqatha kwaye zihlolwe umgangatho. Ezi vavanyo ziquka ukulinganiswa kokumelana nobushushu, umlinganiselo wokujika, umlinganiselo wevolthi, kunye nokulahleka komthwalo. Izixhobo zovavanyo ezikhethekileyo zisetyenziselwa ukuqinisekisa ukuba iitransformer ziyahlangabezana neemfuno ezifunekayo kunye nemigangatho yomgangatho.

a) Umongo weMetal ongama-Amorphous: Ii-core zemetal ezingama-Amorphous, ezidla ngokwenziwa ngee-alloys ezifana ne-amorphous metal esekwe kwi-iron, ziye zathandwa ngenxa yeempawu zazo ezintle zemagnethi. Ezi-cores zinciphisa kakhulu ukulahleka kwamandla, nto leyo ebangela ukuba kubekho ii-transformers ezisebenzayo kakhulu.

b) IiTransformers zohlobo olomileyo: Iitransformers zemveli ezizaliswe lulwelo zitshintshwa kancinci kancinci ziitransformers zohlobo olomileyo. Ezi transformers zisusa iingozi ezinxulumene neetransformers ezizaliswe yioyile, ezifana nokuvuza kunye neengozi zomlilo. Iitransformers zohlobo olomileyo zisebenzisa izinto zokukhusela ubushushu eziqinileyo, nto leyo ezenza zibe nobuhlobo ngakumbi nokusingqongileyo.

c) Iinkqubo Zokupholisa Ezinobuhlobo Nokusingqongileyo: Ii-ester ezenziweyo, ezifana nee-ester ezisekelwe kwimifuno, zisetyenziswa njengezinye iindlela endaweni yeoyile yeminerali kwiitransformer zokupholisa. Ezi ester ziyabola, azinatyhefu, kwaye azitshisi kakhulu, zibonelela ngokhuseleko olongezelelekileyo kunye neenzuzo zokusingqongileyo.

d) Uyilo oluNcinci: Abavelisi beTransformer baqhubeka nokusebenza kwiindlela zoyilo oluNcinci ukunciphisa iimfuno zendawo. Iitransformer eziNcinci, ezifana nezo zinelahleko encinci kunye neewindings ezilungisiweyo, zivumela ukusetyenziswa ngokufanelekileyo kwendawo encinci kwizikhululo.
