Ungakuhlola kanjani ukushintshwa kwe-transformer?

Umthombo Wokuqala: Ukukhanya Kwamadivayisi

Esihlokweni esikhuluma ngokunciphisa izindleko zama-transformer, sixoxe ngokushintsha izinto, ukwenza ngcono inqubo, kanye nezinye izici ezingaholela ezinguqukweni ekusebenzeni kwe-transformer.
Ngakho-ke, enkambisweni yokunciphisa izindleko, ukuhlolwa okunye kuba okubaluleke kakhulu. Lesi sihloko sizoxoxa ngokuqukethwe okufanele kokuhlolwa kokushintshana kwe-transformer kusuka ezicini ezimbili: abakhiqizi be-transformer kanye nabakhiqizi bamandla.
Ukuze kushintshwe izinto, abakhiqizi be-transformer kudingeka bahlole umthelela wayo ku-transformer uqobo. Uma i-magnetic core ishintshwa, into yokuqala okufanele icatshangelwe izinguquko ngobukhulu bayo ezizothinta i-transformer.

Ngisho nangencazelo efanayo kanye nemodeli, amathuluzi okugaya asetshenziswa umenzi ngamunye we-magnetic core avame ukuhluka, okuholela kobukhulu obuhlukahlukene; Umehluko enqubweni yokusila ungaholela ekubekezeleleni okuhlukile kwe-magnetic core, kokubili okungabangela izinguquko ekufanisweni kwe-magnetic core kanye nohlaka lwamathambo. Uma kunezinguquko ezibalulekile eziholela ekungakwazi ukuhlangana noma ukusebenza kahle okuphansi kokuhlanganiswa, akufanele ukulahlekelwa.
Okwesibili, amapharamitha ayisisekelo ezinto eziyinhloko yamagnetic kufanele asondele. Ukuze uthole amapharamitha athile afana nokuvuleka kokuqala kwamagnetic (μ i), ukugcwala kwamandla okufakwa kwamandla kamagnetic (Bs), ukusetshenziswa kwamandla (Pv), izinga lokushisa leCurie (Tc), ubuningi, ukusebenza kokudonsa, ukusebenza kokudlidliza, njll., sicela ubheke isihloko esithi “Amapharamitha Ezimpawu Zama-Magnetic Cores”. Kukhona ithebula lokuqhathanisa izinto embonini njengereferensi, futhi ungathola nabakhiqizi be-magnetic core ukuze bakunikeze.

Ngentambo, izici ezifana nobukhulu befilimu yopende, ubukhulu besendlalelo sokufaka ugesi, usayizi wobubanzi bangaphandle, ukumelana nogesi, izinga lokumelana nokushisa, kanye nomthamo wokufaka ugesi. Ngezintambo ezifakwe ugesi ezinezingqimba ezintathu, kufanele kucatshangelwe isitifiketi sesistimu yokufaka ugesi. Ngokuvamile, izintambo ezifakwe ugesi ezahlukene zinezinhlelo zokufaka ugesi ezahlukene. Ngaphandle kokuthi ikhasimende alidingi uhlelo lokufaka ugesi, lokho kungenye indaba.

Uma kufakwa esikhundleni samathambo, izinto ezifana nezinto zokwakha, ukujiya kodonga, ukufakwa nokususwa kwe-PIN, kanye namandla amathambo kudingeka kucatshangelwe. Into ebaluleke kakhulu ububanzi nobubanzi besikhala, okufanele kugcinwe kufana, ngaphandle kwalokho kuzobangela izinguquko enanini lezingqimba ezigoqayo kanye nokusatshalaliswa kwamajika, futhi ukusebenza kuzoshintsha ngokufanele.

Ukufakwa esikhundleni kwe-transformer, izinto zokuhlola ezijwayelekile zokuphakelwa kukagesi zifaka phakathi ukukhuphuka kwezinga lokushisa, ukusebenza kahle, inani le-PF, i-THD (ukuhlanekezelwa okuphelele kwe-harmonic), izinga lokulungisa, i-ripple, i-EMC, njll., kanye nokuhlolwa kokucindezeleka kwezingxenye ezibalulekile njenge-MOS eyinhloko kanye ne-Schottky diode yesibili. Izinto zokuhlola ukuthembeka zifaka phakathi ukuqalisa kwezinga lokushisa eliphezulu neliphansi, ukuguga kwezinga lokushisa eliphezulu neliphansi, kanye nokuhlolwa kokuthembeka okuphindwe kabili okungu-85.

Ukuzenzakalela kwenqubo kudinga ukuhlangabezana nezidingo eziyisisekelo zamapharamitha eziguquli. Uma kudingeka, ukuhlukaniswa kwenqubo kufanele kwenziwe ukuqinisekisa ukuvumelana komkhiqizo ngesikhathi sokukhiqizwa okuzenzakalelayo nokususa izingozi zekhwalithi.
Ngokuphathelene nokushintshaniswa kwezinto kanye nokwenza ngcono izinqubo, amafektri e-transformer awadingi nje kuphela ukuhlangabezana nemingcele eyisisekelo, kodwa futhi kudingeka ahlangabezane nezimfuneko zokuthembeka. Ukuze uthole imininingwane, sicela ubheke isihloko esandulele esithi “Kuhlanganisani ukuthembeka kwe-transformer.”
Kubakhiqizi bokuhlinzeka ngogesi, ukushintshaniswa kwezinto, ukwenza ngcono inqubo, kanye nokwethulwa kwabaphakeli abasha konke kuyizinguquko ezibalulekile. Ngaphezu kokuqinisekisa amapharamitha ayisisekelo kanye nokuthembeka kweyunithi ye-transformer, kuyadingeka futhi ukuqinisekisa ukusebenza kwe-transformer ekuhlinzekweni kwamandla. Qinisekisa ukuthi okushintshwayo kuyafaneleka futhi kuthembekile, futhi kungahlangabezana nezidingo zomshini wonke ngobuningi.
