Ukucacisa iiMilo ezahlukeneyo zeTransformer Core

Intshayelelo:

Iitransformer zidlala indima ebalulekileyo kwiinkqubo zombane, zidlulisela ngokufanelekileyo amandla ombane ukusuka kwisekethe enye ukuya kwenye. Embindini wetransformer nganye kukho umbindi, onoxanduva lokuguqulwa kwamandla. Iimo zetransformer core zahlukile kakhulu, nganye ineempawu kunye nokusetyenziswa kwayo okwahlukileyo. Kweli nqaku, siza kujonga kwiimo zetransformer core ezahlukeneyo, sihlolisise iimpawu zazo, iingenelo kunye nokusetyenziswa kwazo, sichaze indima yazo kwiinkqubo zombane zanamhlanje.

Imilo yeCore ethi "E"

Imilo yentloko ethi "E" yenye yezona zinto zisetyenziswa kakhulu kwi-transformer core. Igama layo livela kwimbonakalo efana ne-E xa ijongwa kwindawo enqamlezileyo. Intloko ethi "E" inemilenze emibini yangaphandle kunye nomlenze ophakathi oqhagamshelwe yi-joke. Ii-windings zihlala zijikelezwe kumlenze ophakathi. Le milo yentloko ineenzuzo ezininzi, nto leyo eyenza ukuba ithandwe kwiindlela ezahlukeneyo zokusebenza.

Imo ye-"E" core ine-magnetic coupling egqwesileyo, eqinisekisa ukudluliselwa kwamandla ngokufanelekileyo. Uyilo lwayo lunciphisa ubude bendlela ye-magnetic flux, nto leyo ebangela ukulahleka okuphantsi kwe-core. Ukongeza, ii-windings ezimfutshane kumlenze ophakathi zinciphisa ukumelana nokujika, nto leyo ephucula ngakumbi ukusebenza kakuhle. Ezi mpawu zenza imo ye-"E" core ifaneleke kakuhle kwii-transformers zamandla ezisetyenziswa kwizicelo zamandla aphezulu kunye ne-voltage.

Ngaphezu koko, imo ye-"E" core ivumela uyilo oluncinci, oluvumela iingenelo zokonga indawo. Ihlala isetyenziswa kwizixhobo zamandla, kwiitransformer zeaudio, nakwiitransformer ze-switch-mode. Ukuguquguquka kwayo kudlulela kwizicelo apho indawo inqongophele khona, njengakwizixhobo ze-elektroniki, ngenxa yobukhulu bayo obuncinci.

Imo yeCore ethi "U"

Okulandelayo, sihlola imo engundoqo ethi "U", equka imilenze emibini efanayo, enejoko eliyidibanisayo, lenza imo efana nonobumba "U." Olu lwakhiwo lubonelela ngeempawu ezahlukeneyo ezichaphazela ukusetyenziswa kwayo kumashishini ahlukeneyo.

Enye yeenzuzo eziphawulekayo zesimo se-"U" core kukuba ikwazi ukufikelela kwinqanaba eliphezulu le-magnetic flux, nokuba inendawo encinci enqamlezileyo. Olu phawu luzivumela kakuhle ii-transformers ezisetyenziswa kwizicelo ze-high-frequency, apho ukunciphisa ilahleko ze-core kubalulekile. Amandla e-"U" core okusingatha imisinga ye-high-frequency, kunye nobukhulu obuncinci, okwenza kube lukhetho olufanelekileyo kwii-transformers ze-inverter, ii-transformers ze-flyback, kunye nokunye.

Imo yentloko ethi "U" ixhaphake kakhulu kwizixhobo zonxibelelwano, izixhobo zamandla ezingenakunqandeka (ii-UPS), kunye nezinye ii-transformers ezine-frequency ephezulu.

Imo yeCore "yeToroidal"

Sisebenzisa indlela eyahlukileyo, ngoku sijika ingqalelo yethu kwimilo engundoqo ye "toroidal" eyahlukileyo. Ngokungafaniyo nemilo engundoqo yangaphambili, imilo ye-toroidal yenza isakhiwo esifana ne-donut, esinee-windings ezijikeleza umjikelo wonke. Olu yilo lubonelela ngeenzuzo ezahlukeneyo kwaye lusetyenziswa rhoqo kwizicelo ezahlukeneyo.

Enye yezona nzuzo ziphambili zesimo se-toroidal core kukulingana kwayo okumangalisayo kwemagnethi. Imigca ye-magnetic flux ivalelwe ngaphakathi kwe-core, nto leyo ekhokelela ekunciphiseni ukuvuza kunye nokusasazeka. Olu phawu lunciphisa ukulahleka kwe-core, nto leyo ekhokelela ekusebenzeni ngcono. Ukongeza, ukulingana kwe-toroidal core kunciphisa intsimi ye-magnetic yangaphandle kunye nokuphazamiseka kwe-electromagnetic (EMI). Ke ngoko, lukhetho oluhle kakhulu kwizicelo ezinobuthathaka kwi-EMI, ezifana nezixhobo zesandi kunye nezixhobo zonyango.

Ngaphezu koko, imilo ye-toroidal core inika isisombululo esincinci nesikhaphukhaphu ukuhlangabezana neemfuno zoyilo lwanamhlanje. Ngenxa yendlela yayo yemagnethi evaliweyo, ii-transformers ze-toroidal zibonisa amasimi emagnethi angaphandle aphantsi. Olu phawu lubenza bafaneleke kwiindawo ezinqongopheleyo, apho ezinye iimilo ze-core zinokubangela ukuphazamiseka okungafunekiyo. Izicelo ezixhamlayo kwimilo ye-toroidal ziquka izixhobo zamandla, ii-amplifiers zesandi, kunye nee-amplifiers zegitare.

Imo "yePot Core"

Ukuqhubela phambili, makhe sihlolisise imo yentloko eyahlukileyo "yembiza" okanye "yendebe". Le milo ineziqingatha ezibini ezisilinda ezidityanisiweyo, kunye neengcingo ezikwindawo ephakathi. Uyilo lwentloko yembiza luneempawu ezikhethekileyo ezenza ukuba ifaneleke kakuhle kwizicelo ezithile.

Enye yeenzuzo eziphambili zesimo se-pot core kukukwazi kwayo ukusingatha uxinano oluphezulu lwe-magnetic flux. Ukujikajika kwi-central cavity kuvumela indlela emfutshane ye-magnetic, nto leyo ebangela ukulahleka okuphantsi kwe-core kunye nokusebenza ngcono. Olu phawu lwenza isimo se-pot core sithandwe kakhulu kwii-power transformers kunye nee-inductors ezisetyenziswa kwiindawo apho kufuneka uxinano oluphezulu lwamandla.

Ngaphezu koko, imilo yentloko yembiza ineempawu ezintle zokukhusela. Isekethe yemagnethi evaliweyo eyilwayo inciphisa imitha ye-electromagnetic, nto leyo eyenza ukuba ifaneleke ukusetyenziswa apho i-EMI kufuneka incitshiswe. Ukongeza, isakhiwo se-cylindrical sivumela ukupholisa okusebenzayo, okuqinisekisa ulawulo olufanelekileyo lobushushu kwii-transformers ezinamandla aphezulu.

Imo ye-pot core ifumana usetyenziso kwizixhobo zombane ezitshintshiweyo, kwii-power converters, nakwii-industrial transformers. Ubuchule bayo bokuphatha i-magnetic flux ephezulu kunye neempawu zokukhusela buyenza ibe lolona khetho luphezulu kumashishini e-electronics.

Imilo yeCore "EI"

Okokugqibela kodwa okungabalulekanga, sijonga kwimo ye-"EI" core, edibanisa izinto ezivela kwimo ye-"E" kunye ne-"I". Olu lwakhiwo luqulathe imilenze emibini yangaphandle efana ne-"E" kunye nomlenze ophakathi ofana ne-"I" onedyokhwe edibanisa zona. Imo ye-"EI" core inikezela ngeenzuzo ezininzi ezifanelekileyo kwiintlobo ngeentlobo zezicelo.

Imo ye-"EI" core idibanisa iingenelo ze-"E" core, ezinje ngokuncipha kokulahleka kwe-core kunye nokusebenza kakuhle ngokubanzi, kunye nendawo ekhulayo yefestile yokujika ye-"I" core. Olu dibaniso luphumela kwimo ye-core ekwaziyo ukuphatha amanqanaba aphezulu e-magnetic flux kunye neendlela eziphuculweyo zokujika. Ngenxa yoko, imo ye-"EI" core isetyenziswa kakhulu kwii-transformers zokusasaza, ii-transformers ze-medium-frequency kunye ne-high-frequency, kunye nezixhobo ezahlukeneyo zombane.

Ngaphezu koko, imo yentloko ye-"EI" inika uzinzo oluhle loomatshini kwaye inciphisa amanqanaba engxolo evakalayo. Ulwakhiwo olune-laminated lunciphisa ukungcangcazela kunye nokunciphisa amandla ombane, luqinisekisa ukusebenza okuzolileyo. Olu phawu, kunye neempawu zalo ezibalaseleyo zemagnethi, lwenza imo yentloko ye-"EI" ifaneleke kwizicelo ezifana nezixhobo zesandi, ii-amplifier zamandla, kunye nee-transformers zezixhobo.

Ngamafutshane, ukuqonda iimilo ezahlukeneyo ze-transformer core kubalulekile ekukhetheni uqwalaselo olufanelekileyo lwezicelo ezahlukeneyo zombane. Iimilo nganye inika iingenelo ezikhethekileyo ezichaphazela ukusebenza kakuhle, ukusetyenziswa kwendawo, iimpawu zemagnethi, kunye nokuqwalaselwa kwe-EMI. Ukususela kwiimilo ze-"E" kunye ne-"U" core ezisetyenziswa kakhulu ukuya kwiimilo ezikhethekileyo ze-"toroidal," "pot," kunye ne-"EI", ukuguquguquka kwee-transformer cores kuvumela izisombululo ezenzelwe wena ukuhlangabezana neemfuno ezahlukeneyo zoshishino.

Isiphelo:
