Kwi-Delta-Star Connection of Transformers, eyona nto iphambili idityaniswe ne-delta wiring ngelixa i-second current idibanisa kwenkwenkwezi. Uqhagamshelo lwaqala ukusetyenziswa ngokubanzi ukunyusa amandla ombane kwinkqubo yothumelo loxinzelelo oluphezulu kwaye ukusukela ngoko luye lwafumana ukuthandwa ngakumbi njengendlela yokuhambisa amandla ngokufanelekileyo kwimigama emide kuba inokumiselwa kulo naluphi na uhlobo lomthwalo.
Kule posi siza kugubungela:
- Yintoni ukusetyenziswa kweNkwenkwezi kunye neDelta Connection?

Yintoni ukusetyenziswa kweNkwenkwezi kunye neDelta Connection?
Inkwenkwezi kunye noQhagamshelo lweDelta zezona zixhaphakileyo zokuqalisa amandla ombane ezincitshisiweyo kwiinjini. Uqhagamshelo lweNkwenkwezi/Delta luzama ukunciphisa isiqalo sangoku ngokusika amandla kwisiqingatha, okunciphisa ukuphazamiseka kwiintambo zamandla kunye nokuphazamiseka okubangelwa ngexesha lokuqalisa i-motor.
Yeyiphi engcono iNkwenkwezi okanye iDilta Connection?
UQhagamshelwano lweDelta luhlala lusetyenziswa kwizicelo ezifuna itorque ephezulu. Udibaniso lweenkwenkwezi, kwelinye icala, luthatha ukugquma okuncinci kwaye lunokusetyenziswa kwimigama emide apho amandla afuneka khona.
Kwenzeka ntoni xa inkwenkwezi iqhagamshelwe okanye i-delta iqhagamshelwe?
Kwenzeka ntoni xa uneNkwenkwezi kunye neDelta eqhagamshelene neemotor? Xa izigaba ezibini zisabelana nge-voltage, zinokuthiwa ziqhagamshelwe inkwenkwezi. Ukuba isigaba ngasinye sinomgca waso opheleleyo wombane ngoko kuya kuthiwa yi-delta connections.
Uthini umahluko phakathi kwenkwenkwezi kunye ne-delta edibeneyo yenkqubo?
Kuqhagamshelo lweDelta, isiphelo sekhoyili nganye siqhagamshelwe kwindawo yokuqala kwenye. Iitheminali ezichaseneyo nazo ziqhagamshelwe kunye kolu hlobo lwenkqubo-nto leyo ethetha ukuba umgca wangoku ulingana nengcambu yesigaba sangoku ngokuphindwe kathathu. Ngokwahlukileyo, kunye ne-Star configuration voltage ("umgca") imisinga elinganayo ngezigaba; Nangona kunjalo, akunamsebenzi ukuba uqala kweliphi isebe kuba zombini iikhoyili ziya kuba nombane ofanayo xa zisebenza ngemagnethi ngokupheleleyo.
Yintoni inzuzo yoQhagamshelwano lweDelta?
Uqhagamshelo lweDelta lukhetho olukhulu xa ukuthembeka kubalulekile. Ukuba enye yee-winding ezintathu eziphambili iyasilela, iDelta isenokusebenza ngezigaba ezibini zokugcina izinto zihamba kakuhle. Ekuphela kwemfuneko kukuba ezi zimbini ziseleyo zomelele ngokwaneleyo ukuba zikwazi ukuthwala umthwalo wakho kwaye awuyi kuphawula nawuphi na umahluko kumbane okanye umgangatho wamandla!
Kutheni i-Delta Connection isetyenziswa kwi-motor induction?
UQhagamshelwano lweDelta lusetyenziswa kwiimotor induction ngenxa yezizathu ezininzi. Okokuqala, ibonelela ngamandla amaninzi kunye netorque yokuqala kunodibaniso lweNkwenkwezi ngenxa yendlela uqhagamshelo lwayo olucwangciswe ngayo ngaphakathi kwemoto ngokwayo: ngelixa uqwalaselo lwenkwenkwezi lunomoya omnye oqhagamshelwe kumacala amabini atshintshanayo (uhlobo “Y”), idelta-wye. Ukucwangciswa kusebenzisa amajiko-jiko amathathu enye nenye edityaniswe ngokwahlukeneyo kwincam ezichaseneyo zeshafti ye-armature ukuze zenze iiengile ngokubhekiselele kumgca wabo osembindini onokuhluka phakathi kwe-120 ° kunye ne-180 ° kuxhomekeke kwinqanaba lokuqala lokuzilinganisa. Ngaphaya koko, ngenxa yokuqina kobu bunzima bejiyometri ngokuchaseneyo kungabikho hlanganiso apho ezi ngalo zidibana khona njengoyilo lwe-Y - oluguqukayo xa luchaphazeleka ngoku.
Ngaba iNkwenkwezi okanye iDelta izoba yangoku ngakumbi?
Ukuba "unomthwalo oqhubekayo" (ngokwemiqathango ye-torque) ngoko i-Delta iya kutsala ngaphantsi kwangoku kwisigaba ngasinye xa isebenza kwi-delta, kodwa ukuba isicelo sakho sifuna ukukhutshwa kwamandla rhoqo okanye imithwalo enzima, iNkwenkwezi inenzuzo ngenxa yokuba inamandla aphindwe kathathu.
