Ukujonga Ngaphakathi Iinxalenye zoMbane zeTransformer Box kunye neeSekethe

Iitransformer zizinto ezibalulekileyo kwiinkqubo zombane, zibonelela ngosasazo lwamandla olukhuselekileyo nolusebenzayo. Emva komphandle obonakala ulula webhokisi yetransformer kukho uthungelwano oluntsonkothileyo lwezixhobo zombane kunye neesekethe. Kweli nqaku, siza kujonga nzulu ukusebenza kwangaphakathi kweebhokisi zetransformer, sihlola izixhobo zazo zombane eziphambili kunye neesekethe ezintsonkothileyo ezizivumela ukuba zisebenze ngokufanelekileyo. Makhe sihlolisise ihlabathi elinomdla lezixhobo zombane zebhokisi yetransformer kunye neesekethe.

I-Transformer Core: Apho Konke Kuqala Khona

Intliziyo yetransformer nganye ikwimo yayo engundoqo, into ebalulekileyo enoxanduva lokuguqulwa kwamandla kwisixhobo. Ngokwesiqhelo yenziwe ngeeshiti zesinyithi zesilicon ezifakwe ilaminate, imo engundoqo isebenzela iinjongo ezimbini ezibalulekileyo: ukubonelela ngendlela yokujikeleza kwamandla kunye nokunciphisa ukulahleka kwamandla. Ulwakhiwo olufakwe ilaminate lwemo engundoqo lunceda ukunciphisa imisinga ye-eddy, enokubangela ukuchithwa kwamandla okungeyomfuneko. Olu khetho loyilo luphucula ukusebenza kakuhle kunye nokuthembeka kwetransformer.

Ngaphakathi kwi-magnetic core, kukho ii-windings ezimbini ezahlukeneyo: ii-windings eziphambili nezesibini. I-windings eziphambili zifumana amandla ombane avela kumthombo wamandla, njengesityalo samandla okanye i-substation. Okwangoku, i-winding yesibini inika i-voltage eguquliweyo kumthwalo, iqinisekisa ukusebenza kakuhle kwezixhobo zombane eziqhagamshelwe kwi-transformer.

Ukungena nokuphuma kweBushings

Ii-bushings zizinto ezibalulekileyo kwibhokisi ye-transformer, zisebenza njengonxibelelwano phakathi kwemithombo yamandla yangaphandle kunye neesekethe zangaphakathi. Ezi zakhiwo zokukhusela iityhubhu zidibanisa ii-windings ze-transformer nezixhobo zombane zangaphandle kunye nolawulo. Ii-bushings zibonelela ngendlela egqunyiweyo yamandla ombane, zinciphisa umngcipheko weesekethe ezimfutshane okanye ukutshayiswa kombane. Zikwadlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokukhuselekileyo kwe-transformer ngokuthintela ukufuma okanye ukungcola ukuba kungangeni kwiindawo zangaphakathi.

Ii-bushings zihlala zenziwe ngezinto zokukhusela ezifana ne-porcelain okanye ii-polymers ezidityanisiweyo. Ukukhethwa kwezinto kuxhomekeke kwizinto ezahlukeneyo, kubandakanya i-voltage yokusebenza, iimeko zokusingqongileyo, kunye neemfuno ezithile zokusetyenziswa. Ii-bushings ze-porcelain zinika amandla abalaseleyo oomatshini kunye neempawu zokukhusela umbane, nto leyo ezenza zifaneleke ukusetyenziswa kwe-voltage ephezulu. Kwelinye icala, ii-bushings ze-polymer ezidityanisiweyo zibonelela ngeenzuzo ezifana nobunzima obulula, ukumelana nokugqwala, kunye neempawu zokhuseleko eziphuculweyo.

Ukuqonda Abatshintshi beTap

Izitshintshi zetaphu zizixhobo ezibalulekileyo ezisetyenziswa kwiibhokisi zetransformer ukulawula i-voltage yokuphuma ngokweemeko ezahlukeneyo zomthwalo. Ezi zixhobo zivumela uhlengahlengiso kwi-turns ratio yee-transformer windings, nto leyo evumela ulawulo oluchanekileyo kwi-output voltage. Izitshintshi zetaphu zibaluleke kakhulu kwiimeko apho i-voltage enikezelwa yigridi yamandla itshintshatshintsha kakhulu.

Kukho iintlobo ezimbini eziphambili zezitshintshi zetaphu: izitshintshi zetaphu ezikwi-load (OLTC) kunye nezitshintshi zetaphu ezikwi-off-circuit (OCTC). Ii-OLTC zibonelela ngenzuzo yokulungisa indawo yetaphu ngelixa i-transformer ihlala inamandla, okuvumela ukusebenza okuqhubekayo ngaphandle kokuphazamisa umbane. Nangona kunjalo, ii-OCTC zifuna ukukhupha i-transformer kumthombo wamandla ngexesha lokutshintsha kwetaphu. Ukukhetha phakathi kwezi ntlobo zimbini kuxhomekeke kwizinto ezahlukeneyo, kubandakanya iimfuno zesicelo, ukuqwalaselwa kweendleko, kunye nokufumaneka kokuphazamiseka kwamandla.

Ukutyhila Indima Yeenkqubo Zokupholisa

Iitransformer, ingakumbi ezo zisebenza phantsi kwemithwalo ephezulu, zifuna iinkqubo zokupholisa ezisebenzayo ukuze zikhuphe ubushushu obugqithisileyo obuveliswa ngexesha lokusebenza kwazo. Ngaphandle kweendlela ezifanelekileyo zokupholisa, ubushushu obugqithisileyo bunokonakalisa izinto zangaphakathi kwaye bubeke emngciphekweni ukusebenza kunye nobomi betransformer iyonke.

Kukho iindlela ezahlukeneyo zokupholisa ezisetyenziswa kwiibhokisi ze-transformer, nganye ineengenelo kunye nemida yayo. Enye indlela yokupholisa esetyenziswa kakhulu kukupholisa nge-oyile, apho i-transformer ifakwa emanzini kwi-tank egcwele i-oyile yokukhusela. I-oyile isebenza njengesibandisi, ikhupha ubushushu kumbindi kunye nee-windings kwaye ibuchitha ngokusebenzisa i-convection yendalo okanye iinkqubo zokujikeleza ezinyanzelekileyo. Ukupholisa nge-oyile kunika iimpawu ezintle zokukhusela kunye nokutshabalalisa ubushushu ngokufanelekileyo, okwenza ukuba ifaneleke kwii-transformer ezinamandla aphezulu.

Enye indlela yokupholisa kukupholisa umoya, apho iifeni okanye i-convection yendalo inceda ukudluliselwa kobushushu ukusuka embindini kunye nee-windings ukuya emoyeni ojikelezileyo. Ii-transformers ezipholileyo emoyeni zihlala zisetyenziswa kwiindawo apho imida yendawo okanye izinto ezingqongileyo zithintela ukusetyenziswa kweenkqubo ezifakwe kwi-oyile. Nangona ukupholisa umoya kubonelela ngezisombululo ezingabizi kakhulu nezinobuhlobo nokugcinwa, ukusebenza kwayo kusenokuba ngaphantsi xa kuthelekiswa nokupholisa okufakwe kwi-oyile, ingakumbi kwii-transformers ezinamandla aphezulu.

Ukuqonda i-Complex Circuitry

Ngaphakathi kwibhokisi yetransformer, iisekethe ezintsonkothileyo ziqinisekisa ukuhamba kakuhle kwamandla ombane kwaye zithintela naluphi na ukuphazamiseka okanye ukusilela. Le sekethe iquka izinto ezininzi, ezinje ngeefusi, iirelayini, iiswitshi, kunye neendlela zokulawula, zisebenza kunye ngaphandle kokuphazamiseka ukukhusela itransformer kunye nokugcina usasazo lwamandla oluthembekileyo.

Iifusi zisebenza njengezixhobo zokhuseleko, zikhusela i-transformer kwimijelo yamandla egqithisileyo enokonakalisa ii-windings okanye ezinye izinto ezibalulekileyo. Zenzelwe ukunyibilikisa nokuphula isekethe yombane xa kufunyenwe amanqanaba angaqhelekanga amandla. Kwelinye icala, ii-relays ziiswitshi ze-electromagnetic ezibona iingxaki ngaphakathi kwi-transformer kwaye ziqalise izenzo zokukhusela. Zidlala indima ebalulekileyo ekuthinteleni iingozi ezinokubakho ezifana nombane ogqithisileyo, umbane ogqithisileyo, okanye ubushushu obugqithisileyo.

Iiswitshi ngaphakathi kwisekethe zivumela ulawulo lwesandla phezu kwetransformer, zivumela abaqhubi ukuba bahlukanise okanye baqhagamshele izinto ezithile okanye iisekethe njengoko kufuneka. Ezi switshi zihlala zixhotyiswe ngeempawu zokhuseleko ukukhusela kwimisebenzi yengozi okanye ukufikelela okungagunyaziswanga. Ukongeza, iindlela zokulawula, ezifana nezilawuli zevolthi okanye iirelay zokukhusela, zijonga kwaye zilungelelanise iiparameter ezahlukeneyo zombane ukuqinisekisa ukusebenza kakuhle kunye nokukhusela itransformer ekonakaleni.

Isiphelo
