Ukuguquguquka kanye nama-Transformers
I-inductance kanye nama-transformer kuyimibono emibili eyisisekelo emhlabeni kagesi, ebusa yonke into mayelana nendlela amandla kagesi akhiqizwa ngayo, adluliselwa ngayo, futhi asetshenziswa ngayo. Ukuqonda kahle le mibono emibili kubalulekile kunoma ubani onentshisekelo kubunjiniyela kagesi kanye nokusetshenziswa kwawo ekuphileni kwansuku zonke.
Ukunyakaza
I-inductance yikhono lengxenye kagesi, njengekhoyili yocingo noma i-solenoid, lokugcina amandla ensimini yamagnetic lapho ugesi ugeleza kuyo. Iyunithi ye-SI yokulinganisa i-inductance yi-Henry (H). I-inductance ivame ukukhonjiswa ngophawu 'L' futhi ingabalwa kusetshenziswa i-equation:
\[ L = \frac{N\Phi}{I} \]
Lapho i-\(N\) iyinombolo yokujika, i-\(\Phi\) iyi-magnetic flux, kanti i-\(I\) iyi-current.
Empeleni, i-inductor yakhiwa yi-coil yocingo, evame ukwenziwa ngethusi, ehlanganiswe ngesimo esithile, njenge-solenoid noma i-toroid. Lapho ugesi udlula kule coil, kudalwa insimu yamagnetic ezungeze ugesi. Izinguquko kugesi zibangela izinguquko kule nsimu yamagnetic, ngokusho koMthetho kaFaraday wokungeniswa kwe-Electromagnetic. Lokhu kubangela ukungeniswa kwe-electromagnetic, okukhiqiza amandla e-electromotive (EMF) aphikisana noshintsho kugesi.
Lesi simiso sibonakala kakhulu ekusetshenzisweni kwama-inductor kumasekethe kagesi. Ama-inductor angasetshenziswa ukuhlunga amaza athile, ukulawula ukushukuma kwamasekethe e-LC, noma njengezinto zokugcina amandla kuma-power converters. Esinye sezicelo eziqondile yi-choke, esetshenziselwa ukuvimba i-AC ngenkathi ivumela i-DC ukuthi idlule.
Kodwa-ke, lapho ama-inductor amaningi ebekwa eduze, udaba olulodwa olubalulekile okufanele lucatshangelwe ukuhlanganiswa kwamagnetic phakathi kwawo, okungabangela ithonya elihlanganisayo. Yilapho ama-transformer eba khona afaneleka kakhulu.
Isiguquli
I-transformer iyithuluzi elishintsha i-voltage kagesi kusuka kwelinye izinga iye kwelinye kusetshenziswa isimiso sokungeniswa kwe-electromagnetic. I-transformer yakhiwe ngama-coil amabili noma ngaphezulu aboshwe eduze kwe-iron core noma enye into ye-ferromagnetic. I-coil eyinhloko ixhunywe emthonjeni wamandla, kanti i-coil yesibili ixhunywe emthwalweni. Ama-transformer angakhuphula (anyuse) noma anciphise (awehlise) i-voltage njengoba kudingeka.
Isimiso sokusebenza se-transformer sisekelwe kuMthetho kaFaraday wokungeniswa kwe-Electromagnetic kanye noMthetho kaLenz. Lapho amandla kagesi e-AC egeleza nge-coil eyinhloko, kukhiqizwa insimu yamagnetic eshintshayo ezungeze yona. Le nsimu yamagnetic eshintshayo bese idlula enkabeni ye-ferromagnetic iye kwi-coil yesibili. Ngokusho koMthetho kaFaraday, insimu yamagnetic eshintshayo izobangela i-EMF kwi-coil yesibili. Ubukhulu balo mbane obangelwayo buxhomeke enanini lokujika kwi-coil yesibili uma kuqhathaniswa ne-coil eyinhloko, ngokusho kwesibalo esilandelayo:
\[ V_s = \frac{N_s}{N_p} \times V_p \]
Kuphi:
– \(V_s\) yi-voltage kuyo yonke ikhoyili yesibili.
– \(V_p\) yi-voltage kuyo yonke ikhoyili eyinhloko.
– \(N_s\) inani lokujika kukhoyili yesibili.
– \(N_p\) inani lokujika kukhoyili eyinhloko.
Indima Yama-Transformers Ezinhlelweni Zamandla Kagesi
Ama-transformer adlala indima ebalulekile ohlelweni lwamandla kagesi emhlabeni jikelele. Enye yezinzuzo eziyinhloko zokusebenzisa i-AC ukuthi i-voltage ingashintshwa kalula kusetshenziswa i-transformer. Isibonelo, ugesi okhiqizwa yizitshalo zamandla ngokuvamile usezingeni eliphansi kakhulu le-voltage, kodwa uguqulwa ube yi-voltage ephezulu kakhulu yokudlulisela ibanga elide. Le nqubo inciphisa ukulahleka kwamandla okubangelwa ukumelana nezintambo.
Lolu hlelo lokusabalalisa amandla olusebenza kahle nolungabizi belungeke lube khona ngaphandle kwama-transformer, aguqule umqondo wokudluliselwa kukagesi. Eziteshini zokusabalalisa, ama-transformer ayadingeka futhi ukuze ehlise i-voltage iye ezingeni elifanele ukusetshenziswa kwasekhaya nasezimbonini.
Umklamo we-Transformer
Umklamo we-transformer awunqunywa nje kuphela ngenani lamajika kodwa futhi nangezinto eziyinhloko kanye nokubekwa kokugoba. Izinto eziyinhloko kumele zibe nokuvuleka okuphezulu ukuze ziqhube kahle insimu yamagnetic, ngokuvamile zisebenzisa insimbi ye-silicon noma i-ferrite. Lokhu kunciphisa i-hysteresis kanye nokulahlekelwa kwamanje kwe-eddy ku-transformer.
Ngaphezu kwalokho, ukucushwa kwe-core kungahluka, njenge-C, E, noma i-toroidal cores. Lokhu kukhetha kusekelwe ekusebenzeni kahle kanye nokusetshenziswa. Isibonelo, ama-transformer e-toroidal anikeza ukusebenza kahle okuphezulu kanye nokuvuza okuphansi kodwa ngokuvamile kubiza kakhulu ukuwakhiqiza.
Izicelo Zokuguqula Empilweni Yansuku Zonke
Ama-transformer awagcini nje ngokusebenza ezinhlelweni zamandla. Inani elikhulayo lezinhlelo zokusebenza zansuku zonke lincike emandleni ama-inductor nama-transformer. Amaselula ashajayo, amathelevishini, kanye nama-adapter konke kusebenzisa ama-mini transformer.
Emkhakheni wezokuxhumana, ama-transformer asetshenziswa kumasekethe e-RF kanye nokuxhumanisa kwe-impedance.
Esinye isithakazelo sisezinhlelweni zezokwelapha, isibonelo, imishini ye-MRI isebenzisa ama-transformer akhethekile ukudala amasimu anamandla kazibuthe adingekayo ekuthwebuleni umzimba womuntu.
Isiphetho
I-inductance kanye nama-transformer kuyimiqondo emibili ebalulekile eyisisekelo sobunjiniyela kagesi. I-inductance idlala indima ebalulekile ekugcinweni kwamandla kanye nokulawulwa kwamanje, kuyilapho ama-transformer evumela ukulungiswa nokuphathwa kwe-voltage kanye ne-current yezinhlelo zokusebenza ezahlukahlukene. Ngokuqonda nokusetshenziswa okufanele, le miqondo emibili inegalelo ezinhlelweni zamandla ezisebenzayo, ukusatshalaliswa kwamandla okuphumelelayo, kanye nokusungula izinto ezintsha emikhakheni eyahlukene yezobuchwepheshe. Ngaphandle kwabo, intuthuko yesimanje kwezobuchwepheshe kagesi ingase ingabi sezingeni layo lamanje.
