IiModeli eziGuquliweyo: Ukulinganisela ukusebenza kakuhle kunye neendleko

Intshayelelo:

Iitransformer zibaluleke kakhulu kwihlabathi lethu lanamhlanje, zidlala indima ebalulekileyo ekusasazweni kwamandla nakwiinkqubo zombane. Ukusebenza kakuhle kunye nokusebenza kakuhle kweendleko zezona zinto zibalulekileyo ekuyilweni kweetransformer, kwaye enye yezinto eziphambili ezichaphazela kakhulu ezi zinto yimilo engundoqo. Iifom zetransformer core zidlala indima ebalulekileyo ekwenzeni ngcono i-magnetic flux kunye nokunciphisa ukulahleka kwamandla. Kweli nqaku, siza kuphonononga ifom zetransformer core ezahlukeneyo kunye nendlela ezifikelela ngayo kumlinganiselo obuthathaka phakathi kokusebenza kakuhle kunye neendleko.

1. Ukubaluleka kweeMilo zeTransformer Core

Ingundoqo yetransformer kulapho kwenzeka khona umlingo. Inoxanduva lokudluliselwa kwamandla ombane ngokufanelekileyo ukusuka kwi-primary ukuya kwi-secondary winding. Imilo ye-core ichaphazela ngokuthe ngqo i-magnetic circuit, echaphazela iiparameter ezininzi ezibalulekileyo ezifana nokusebenza kakuhle, ilahleko, kunye neendleko zizonke.

Imilo engundoqo imisela indlela yokujikeleza kwemagnethi ngaphakathi kwi-transformer. Kufuneka yenziwe ngendlela enciphisa imisinga ye-eddy, ukulahleka kwe-hysteresis, kunye nokujikeleza kokuvuza, ngelixa kwandiswa ukudibana kwemagnethi phakathi kwee-windings. Ukufezekisa olu lungelelwaniso lubuthathaka kufuna ukuqwalaselwa ngononophelo kwemilo engundoqo.

2. Ii-E, I, U, kunye nee-L Core Shapes

Kukho iimilo ezininzi eziqhelekileyo ezisetyenziswa kuyilo lwe-transformer, nganye ineenzuzo zayo kunye notshintsho. Ezine zezona zimilo zisetyenziswa kakhulu yi-E, I, U, kunye ne-L cores.

Imilo ye-core E ifana nonobumba u-"E" kwaye inamanqina amathathu kunye neejoko ezimbini. Uyilo lwayo luvumela indlela emfutshane yemagnethi, kunciphisa umthamo iyonke ye-core. Oku kukhokelela ekongeni iindleko kwizinto nakwimveliso. Nangona kunjalo, imilo ye-core E ichaphazeleka lula kukwanda kwe-magnetic saturation xa ixinana kakhulu, nto leyo ekhokelela ekwandeni kwelahleko ye-core.

Imilo ye-I core ifana ne-E core, kodwa ine-yook enye kuphela, nto leyo ebangela ukuba i-closed magnetic circuit ivalwe. Le milo ibonelela ngokudibanisa okungcono kwe-magnetic kunye nokunciphisa ukuvuza kwamanzi, nto leyo ebangela ukusebenza kakuhle. Nangona kunjalo, i-I core ifuna izinto ezingakumbi ze-core kwaye inomthamo omkhulu, nto leyo ebangela ukunyuka kweendleko.

Imilo ye-U core ifana nonobumba "U" kwaye inelungu elinye elijikelezayo kunye neejoko ezimbini ezilinganayo. Inika ukuvuza okunciphileyo kunye nokulahleka okuphantsi kwe-core xa kuthelekiswa nemilo ye-E core. Imilo ye-U core idla ngokusetyenziswa kwiindawo apho ukulahleka okunciphileyo kubalulekile, njengombane osebenza kakuhle. Nangona kunjalo, uyilo lwe-U core lufuna ukuqwalaselwa ngononophelo ukuze kuncitshiswe ukuvuza kwe-magnetic flux.

Imo ye-L core inamalungu amabini ajikelezayo adityaniswe yi-joke ethe tye. Le milo inika ukuvuza okuncinci kwe-magnetic flux kunye nokulahleka okuphantsi kwe-core. Uyilo lwe-L core luhlala lusetyenziswa kwizicelo eziphantsi apho imida yokuphakama ibaluleke kakhulu. Nangona kunjalo, inokuba neengxaki zokumelana nokujika ngenxa yobude obude be-wind.

3. Izinto ekufuneka ziqwalaselwe ngokusebenza kakuhle

Ukusebenza kakuhle yiparameter ebalulekileyo xa kufikwa ekuyileni ii-transformers. Iimilo ezahlukeneyo ze-core zinokuchaphazela kakhulu ukusebenza kakuhle ngenxa yokwahluka kwelahleko, ngakumbi i-hysteresis kunye nelahleko zamandla e-eddy.

Ukulahleka kwe-Hysteresis kwenzeka kwizinto zemagnethi ngenxa yokuguqulwa kwemagnetization ngexesha lomjikelo ngamnye. Ukukhethwa kwemilo engundoqo kunefuthe lokulahleka kwe-hysteresis, apho iimilo ezithile zibangela ukulahleka okuphantsi kunezinye. Ukulawula ukulahleka kwe-hysteresis kuvumela ukusebenza kakuhle okuphuculweyo kunye nokunciphisa ukuchithwa kwamandla.

Ukulahleka komsinga we-Eddy kuvela kwimisinga ejikelezayo ebangelwa zizinto eziphambili ngenxa yokutshintsha kwentsimi yemagnethi. Ezi lahleko zinokuncitshiswa ngokusebenzisa izinto eziphambili ezifakwe i-laminated okanye ukuphucula imilo ephambili ukuze kuncitshiswe indawo yeluphu. Ukuba nemilo ephambili enciphisa ukulahleka komsinga we-eddy kunceda ekuphuculeni ukusebenza kakuhle kwe-transformer.

4. Iingqwalasela zeendleko

Nangona ukusebenza kakuhle kuyinto ephambili ekufuneka iqwalaselwe, ukuphuculwa kweendleko kubalulekile kubavelisi be-transformer. Ukukhetha imo yesiseko kunokuchaphazela kakhulu iindleko zizonke ze-transformer ngenxa yokusetyenziswa kwezinto kunye nobunzima bokwenziwa kwayo.

Iimilo ze-E kunye ne-U core zihlala zikhethwa xa ukunciphisa iindleko kuyinto ephambili. Ezi milo zinendlela emfutshane yemagnethi, ezifuna izinto ezincinci ze-core. Ukongeza, iinkqubo zokwenza ezi milo zilula kakhulu, nto leyo ebangela ukonga iindleko. Nangona kunjalo, ezi milo zinokukhokelela ekulahlekelweni okukhulu kunye nokusebenza okunciphileyo, ekufuneka kulinganiswe ngononophelo.

Kwelinye icala, iimilo ze-I kunye ne-L core zidla ngokufuna izinto ezingundoqo ngakumbi kwaye zibandakanya iinkqubo zokuvelisa ezintsonkothileyo. Ngenxa yoko, zinokubiza kakhulu xa kuthelekiswa neimilo ze-E kunye ne-U. Ixabiso elonyukileyo lidla ngokuthethelelwa kukuphucula ukusebenza kakuhle kunye nokuncipha kwelahleko ezinikezelwa zezi zakhiwo ze-core.

5. Ukufumana ibhalansi efanelekileyo

Ukuyila i-transformer efikelela kumlinganiselo ofanelekileyo phakathi kokusebenza kakuhle kunye neendleko kufuna ukuqwalaselwa ngononophelo kwezinto ezahlukeneyo. Iimo eziphambili zidlala indima ebalulekileyo ekufezekiseni olu lungelelwaniso. Kubalulekile ukuhlalutya iimfuno ezithile zesicelo se-transformer kunye nokuqwalasela izinto ezifana nokusebenza kakuhle okufunekayo, imida yobukhulu, kunye nemida yohlahlo-lwabiwo mali.

Ukulinganisa iikhompyutha kunye neendlela eziphambili zokubonisa imodeli ziye zaguqula uyilo kunye nokwenza ngcono i-transformer. Ngokusebenzisa ezi zixhobo, iinjineli zinokuvavanya iimilo ezahlukeneyo ze-core kwaye ziqikelele impembelelo yazo ekusebenzeni, zivumela inkqubo yokwenza izigqibo ezinolwazi. Ukukhetha iimilo ze-core efanelekileyo kunokubangela ukusebenza ngcono, ukunciphisa ilahleko, kwaye ekugqibeleni, ukonga iindleko kubavelisi be-transformer kunye nabasebenzisi bokugqibela.

Isiphelo:

Iimilo ze-transformer core zinempembelelo enkulu ekusebenzeni kakuhle nakwixabiso lee-transformer. Ukufikelela kwibhalansi efanelekileyo phakathi kwezi parameter zimbini kubalulekile ekuyileni ii-transformer kwizicelo ezahlukeneyo. Iimilo ze-E, I, U, kunye ne-L core nganye inika iingenelo kunye norhwebo, okuvumela iinjineli ukuba zilungelelanise uyilo ngokweemfuno ezithile.
