Ubushushu bokujika kweTransformer: Ukuqonda iiNguqu

Intshayelelo

Iitransformer ziyinxalenye ebalulekileyo yeenkqubo zombane, ezinoxanduva lokuhambisa nokusasaza amandla ombane ngokufanelekileyo. Enye into ebalulekileyo yokusebenza kwetransformer bubushushu bee-windings zayo. Ubushushu be-winding buchaphazela kakhulu ukusebenza ngokubanzi kunye nokuthembeka kwexesha elide kwetransformer. Ukuqinisekisa ukusebenza kakuhle, kubalulekile ukuqonda izinto ezitshintshayo ezichaphazela ubushushu be-winding. Eli nqaku liza kujonga izinto eziphambili ezichaphazela ubushushu be-winding kwaye libonelela ngengqiqo malunga namaqhinga okujonga ubushushu kunye nokulawula ukuphucula ukusebenza kwetransformer kunye nobude bayo.

Umthwalo oSebenzayo kunye nobushushu obujikelezayo

1. Ukuveliswa koMthwalo kunye noBushushu

Xa i-transformer isebenza, ifumana umthwalo wombane omisela ubungakanani bombane ohamba kwii-windings zayo. Lo mthwalo, omelwe yi-kilovolt-amperes (kVA), udlala indima ebalulekileyo ekuveliseni ubushushu ngaphakathi kwi-transformer. Lo mbane ohamba ngeengcingo ezijikelezayo ubangela ubushushu obungashukumiyo ngenxa yokumelana kwazo okungokwemvelo, okubangela ngokuthe ngqo ukunyuka kobushushu obujikelezayo. Ukongeza, ilahleko ze-magnetic core zivelisa ubushushu obuphakamisa ngakumbi ubushushu ngokubanzi.

2. Utshintsho lomthwalo kunye nefuthe lobushushu

Ukuguquguquka komthwalo ofunyanwa yitransformer kuchaphazela ngokuthe ngqo ubushushu bokujika. Imithwalo ephezulu ibangela ukunyuka kokuhamba kwamandla ombane kunye nokufudumeza okuphezulu okulandelayo, okukhokelela kubushushu obuphezulu bokujika. Ngokwahlukileyo koko, ngexesha lomthwalo olula, amandla ombane ayancipha, okubangela ukwehla kokuveliswa kobushushu kunye nobushushu obupholileyo bokujika. Utshintsho olunjalo lomthwalo luxinzelela inkqubo yokukhusela yetransformer kwaye luchaphazela ubomi bayo bonke. Ukunciphisa ezi ziphumo, ukuqonda ipateni yomthwalo kunye nokusebenzisa amaqhinga okulawula umthwalo kubalulekile.

Okusingqongileyo kunye nobushushu obujikelezayo

1. Ubushushu obuphakathi

Ubushushu obujikeleze i-transformer buchaphazela kakhulu ubushushu obujikelezayo. Ii-transformer zihlala zinereyithingi yokunyuka kwazo okuvumelekileyo ngaphezu kwe-ambient ejikelezileyo. Ngoko ke, umahluko phakathi kobushushu obujikeleze i-ambient kunye nobushushu obujikelezayo umele umda wobushushu we-transformer. Ubushushu obuphezulu obujikeleze i-ambient buyawunciphisa lo mda wobushushu, nto leyo echaphazela ngokuthe ngqo ubomi be-transformer. Iimeko zobushushu obujikeleze i-ambient ezigqithisileyo zinokubangela ukunyuka kobushushu obujikeleze i-winding kwaye zinokubangela ukuguga ngokukhawuleza kunye nokungaphumeleli.

2. Iinkqubo zokungenisa umoya kunye nokupholisa

Ukuze kuliwe nobushushu obuphezulu bemozulu, ii-transformer zixhotyiswe ngeendlela ezahlukeneyo zokupholisa. Iinkqubo zokupholisa umoya ezinyanzelisiweyo okanye iindlela zokupholisa ezisekelwe kwioyile ezifana nee-radiator okanye ii-heat exchangers zinceda ekususeni ubushushu obugqithisileyo kwaye zigcine ubushushu obujikelezayo ngaphakathi kwemida eyamkelekileyo. Ukusebenzisa iinkqubo ezifanelekileyo zokungenisa umoya kunye nokupholisa kubalulekile ukuphucula ukusebenza kakuhle kokupholisa kwe-transformer kunye nokuqinisekisa ukusebenza kakuhle.

Inkqubo yokuvala ubushushu kunye nobushushu obujikelezayo

1. Iklasi yoKhuseleko

Inkqubo yokwambathisa esetyenziswa kwii-transformer windings idlala indima ebalulekileyo ekumiseleni ukunyuka kobushushu okuvumelekileyo kunye nokusebenza ngokubanzi. Izixhobo zokwambathisa ezifana nephepha, ioyile, kunye nezinto ezahlukeneyo zokwenziwa zisetyenziselwa ukubonelela ngokwahlulwa kombane kunye nokukhuselwa kobushushu phakathi kwezinto eziqhubayo. Ezi zixhobo zokwambathisa zinezakhono ezahlukeneyo zobushushu, ezibonakaliswa ziiklasi zokwambathisa. Iiklasi zokwambathisa eziphezulu zibonelela ngokumelana okungcono kobushushu, okuvumela ii-transformer ukuba zisebenze kumaqondo obushushu aphezulu. Ukuqonda udidi lokwambathisa lwe-transformer kubalulekile ukuqinisekisa uluhlu lobushushu olusebenzayo olukhuselekileyo.

2. Ukuguga kwe-Insulation kunye nobushushu obujikelezayo

Ekuhambeni kwexesha, izinto zokwambathisa kwi-transformers ziqala ukonakala ngenxa yezinto ezahlukeneyo ezifana nobushushu, ukufuma, uxinzelelo lombane, kunye nongcoliseko. Le nkqubo yokwambathisa inciphisa ukumelana nobushushu kwe-insulation kwaye inyusa umngcipheko wokungaphumeleli kwe-insulation. Njengoko i-insulation ibuthathaka, ubushushu bokwambathisa buyanyuka, nto leyo ekhawulezisa inkqubo yokwambathisa kwaye inokukhokelela ekusileleni okukhulu. Ukubeka iliso kubushushu bokwambathisa rhoqo kubalulekile ukuze kubonwe naluphi na utshintsho olukhawulezileyo kubushushu obuqhelekileyo bokusebenza, okuvumela ukugcinwa kwangaphambili kunye nokunciphisa umngcipheko wokungaphumeleli kwe-insulation.

Ukubeka iliso kunye noLawulo lobushushu

1. Izinzwa zobushushu

Ukuqinisekisa ukusebenza kakuhle kwe-transformer, kusetyenziswa ii-temperature sensors ukujonga nokulawula ubushushu obujikelezayo. Ii-thermocouples okanye ii-resistance temperature detectors (RTDs) zihlala zisetyenziswa ukulinganisa ubushushu ngokuchanekileyo. Ezi sensors zibekwe ngobuchule kwiindawo ezibalulekileyo ngaphakathi kwe-transformer, njengakwi-windings, cores, kunye neenkqubo zokupholisa, zibonelela ngedatha yobushushu yexesha langempela yokulawula ubushushu ngempumelelo kunye nokugcinwa kokuthintela.

2. Abatshintshi beeTap abakwiLayishayo

Ii-on-load tap changer (ii-OLTC) zizixhobo ezifakwe kwii-transformer ukuze zilungelelanise umlinganiselo wokujika kwe-transformer kunye nokubuyisela utshintsho lomthwalo. Ii-OLTC zikwachaphazela ubushushu bokujika kwe-transformer ngokuchaphazela ukusasazwa komthwalo phakathi kwee-windings ezahlukeneyo. Ulawulo lwe-OLTC olusebenzayo lunokuphucula ukunyuka kobushushu, luqinisekise ukuchithwa kobushushu okufanayo kwii-windings kwaye lwandise ubude bobomi be-transformer.
