Uxhumano lwenkanyezi ye-Delta

Ku-Delta-Star Connection of Transformers, okuyinhloko kuxhunywe ne-delta wiring kuyilapho okwamanje kwesibili kuxhuma kunkanyezi. Uxhumano lwaqala ukusetshenziswa kabanzi ukuze kunyuswe i-voltage ohlelweni lokudluliswa kwe-tension ephezulu futhi kusukela ngaleso sikhathi beluthola ukuduma okwengeziwe njengendlela yokudlulisa amandla ngendlela efanele emabangeni amade ngoba lungalungiselelwa noma yiluphi uhlobo lomthwalo.

Iyini ukusetshenziswa kwe-Star ne-Delta Connection?

I-Star ne-Delta Connection yiziqalisi ezincishisiwe ezivame kakhulu zamamotho. Ukuxhuma kwenkanyezi/i-Delta kuzama ukunciphisa amandla okuqala ngokusika amandla phakathi, okunciphisa ukuphazamiseka kwezintambo zikagesi kanye nokuphazamiseka okubangwa phakathi nokuqaliswa kwenjini.

Yikuphi okungcono I-Star noma i-Delta Connection?

I-Delta Connections ivame ukusetshenziswa ezinhlelweni ezidinga i-torque ephezulu yokuqala. Ukuxhumana kwezinkanyezi, ngakolunye uhlangothi, kuthatha i-insulation encane futhi kungasetshenziswa amabanga amade amaningi lapho kudingeka khona amandla.

Kwenzekani uma inkanyezi ixhumekile noma i-delta ixhumekile?

Kwenzekani uma uxhume izinjini ze-Star ne-Delta? Uma lezi zigaba ezimbili zabelana nge-voltage, zingabizwa ngokuthi zixhunywe inkanyezi. Uma isigaba ngasinye sinolayini waso ophelele kagesi kuzobizwa ngokuthi ama-delta connections.

Uyini umehluko phakathi kwesistimu exhunyiwe yenkanyezi ne-delta?

Ekuxhumekeni kwe-Delta, ukuphela kwekhoyili ngayinye kuxhunywe lapho kuqalwa khona enye. Amatheminali aphambene nawo axhunywe ndawonye kulolu hlobo lwesistimu–okusho ukuthi umugqa wamanje ulingana nesigaba samanje sesigaba sezimpande esiphindwe kathathu. Ngokuphambene, ne-Star configuration voltage (“umugqa”) imisinga ilingana nezigaba; nokho akunandaba ukuthi uqala kuliphi igatsha ngoba womabili amakhoyili azoba nama-voltage afanayo lapho esenziwe uzibuthe ngokugcwele.

Iyini inzuzo ye-Delta Connection?

I-Delta Connection iyindlela enhle uma ukwethembeka kubalulekile. Uma okukodwa kwezintathu eziyinhloko zehluleka, i-Delta isengakwazi ukusebenza ngezigaba ezimbili ezigcina izinto zihamba kahle. Okuwukuphela kwemfuneko ukuthi ezimbili ezisele ziqine ngokwanele ukuthwala umthwalo wakho futhi ngeke uqaphele noma yimuphi umehluko ku-voltage noma ikhwalithi yamandla!

Kungani kusetshenziswa i-Delta Connection ku-induction motor?

I-Delta Connection isetshenziswa kuma-induction motors ngezizathu ezimbalwa. Okokuqala, inikeza amandla amaningi kanye ne-torque yokuqala kunoxhumano Lwenkanyezi ngenxa yokuthi ukuxhumana kwayo kuhlelwe kanjani ngaphakathi kwenjini ngokwayo: kanti ukumiswa kwenkanyezi kunomoya owodwa oxhunywe kokubili kusuka ezinhlangothini ezishintshanayo (uhlobo luka-"Y"), i-delta-wye. ukuhleleka kusebenzisa amawindi amathathu ngalinye elinamathiselwe ngokuhlukene emaphethelweni ahlukene e-armature shaft ukuze akhe ama-engeli ngokuphathelene nomugqa wawo omaphakathi ongahluka phakathi kuka-120° no-180° kuye ngokuthi uqala nini ukuwakala. Ngaphezu kwalokho, ngenxa yokuqina kwemvelo kwale geometry ngokuphikisana nokungabi khona kwelunga lapho lezi zingalo zihlangana khona njengomklamo ongu-Y - oguqukayo lapho uthintwa amandla amanje.

Ingabe i-Star noma i-Delta idonsa okwakamuva kakhulu?

Uma “unomthwalo ongaguquki” (ngokwetorque) i-Delta izodonsa kancane okwamanje ngesigaba ngasinye lapho isebenza ku-delta, kodwa uma uhlelo lwakho lokusebenza ludinga ukuphuma kwamandla okungaguquki noma imithwalo esindayo, i-Star inenzuzo ngoba inamandla aphindwe kathathu.

Ngingu-Joost Nusselder, umsunguli we-Tools Doctor, umakethi wokuqukethwe, kanye nobaba. Ngiyakuthanda ukuzama okokusebenza okusha, futhi kanye nethimba lami ngidale izindatshana zebhulogi ezijulile kusukela ngo-2016 ukuze ngisize abafundi abathembekile ngamathuluzi namathiphu okwenza.
