Kuchinja uye Kushandura
Inductance nematransformer ipfungwa mbiri huru munyika yemagetsi, zvichitonga zvese zvinoitwa pakugadzirwa, kufambiswa, uye kushandiswa kwesimba remagetsi. Kunzwisisa kwakakwana pfungwa idzi mbiri kwakakosha kune chero munhu anofarira engineering yemagetsi uye mashandisirwo ayo muhupenyu hwezuva nezuva.
Kufambiswa kwesimba
Kupinza simba (inductance) kugona kwechinhu chemagetsi, senge waya kana solenoid, kuchengetedza simba mumunda wemagineti kana magetsi achipfuura nepakati pawo. Chikamu cheSI chekuyera inductance ndiHenry (H). Kupinza simba (inductance) kunowanzo ratidzwa nechiratidzo 'L' uye kunogona kuverengerwa uchishandisa equation:
\[ L = \frac{N\Phi}{I} \]
Apo \(N\) iri nhamba yekutenderera, \(\Phi\) ndiyo magnetic flux, uye \(I\) ndiyo current.
Chaizvoizvo, inductor inoumbwa ne coil yewaya, inowanzogadzirwa nemhangura, yakakomberedzwa kuita chimiro chakati, senge solenoid kana toroid. Kana magetsi emagetsi apfuura nepa coil iyi, simba remagineti rinogadzirwa rakatenderedza waya. Kuchinja kwemagetsi emagetsi kunokonzera shanduko mumunda uyu wemagineti, zvichienderana neMutemo waFaraday weElectromagnetic Induction. Izvi zvinokonzera electromagnetic induction, iyo inoburitsa simba remagineti (EMF) rinopesana nekuchinja kwemagetsi.
Pfungwa iyi inonyanya kuoneka mukushandiswa kwema inductors muma electronic circuits. Ma inductors anogona kushandiswa kusefa mamwe ma frequency, kudzora oscillations muma LC circuits, kana sezvinhu zvekuchengetedza simba muma power converters. Imwe nzira inoshanda ndeye choke, iyo inoshandiswa kuvharira AC uku ichibvumira DC kupfuura nepakati.
Zvisinei, kana ma inductor akawanda akaiswa pedyo, nyaya imwe inokosha yekufunga nezvayo ndeyekubatana kwemagineti pakati pawo, izvo zvinogona kukonzera kupindirana. Apa ndipo panonyanya kukosha ma transformer.
transformer
Transformer mudziyo unoshandura magetsi kubva padanho rimwe kuenda kune rimwe uchishandisa musimboti we electromagnetic induction. Transformer ine ma coil maviri kana anopfuura akatenderedzwa pa core yesimbi kana chimwe chinhu che ferromagnetic. Coil yekutanga yakabatana ne power source, uye coil yechipiri yakabatana nemutoro. Ma transformer anogona kuwedzera (kukwira) kana kuderedza (kudzikisa) voltage sezvinodiwa.
Pfungwa yekushanda kwetransformer inobva paMutemo waFaraday weElectromagnetic Induction neMutemo waLenz. Kana AC current ichipfuura nepakati pe primary coil, simba remagineti rinoshanduka rinogadzirwa rakaipoteredza. Simba remagineti iri rinoshanduka rinobva rapfuura nepakati pe ferromagnetic kuenda ku secondary coil. Sekureva kweMutemo waFaraday, simba remagineti rinoshanduka richakonzera EMF mu secondary coil. Hukuru hwe voltage iyi induced hunoenderana nehuwandu hwekutenderera mu secondary coil zvichienzaniswa ne primary coil, zvichienderana ne equation inotevera:
\[ V_s = \frac{N_s}{N_p} \times V_p \]
di mana:
– \(V_s\) ndiyo voltage iri pamusoro pe coil yechipiri.
– \(V_p\) ndiyo voltage iri pamusoro pe primary coil.
– \(N_s\) ndiyo nhamba yekutenderera mu coil yechipiri.
– \(N_p\) ndiyo nhamba yekutenderera mu coil yekutanga.
Basa reVashanduri muMasisitimu eMagetsi
Matransformer anoita basa rakakosha mumagetsi epasi rose. Chimwe chezvakanakira zvikuru zvekushandisa AC ndechekuti magetsi anogona kuchinjwa zviri nyore uchishandisa transformer. Semuenzaniso, magetsi anowanikwa kubva kumafekitori emagetsi anowanzova padanho remagetsi rakaderera, asi anoshandurwa kuita magetsi akakwira kwazvo ekutumira kure. Maitiro aya anoderedza kurasikirwa kwemagetsi kunokonzerwa nekusasimba kwetambo.
Sisitimu iyi yekugovera magetsi inoshanda uye isingadhuri yaisazokwanisika pasina matransformer, ayo akachinja pfungwa yekutapurirana kwemagetsi. Pazviteshi zvekugovera magetsi, matransformer anodiwa zvakare kuti aderedze voltage kusvika padanho rakakodzera kushandiswa mudzimba nemumaindasitiri.
Dhizaini yeTransformer
Dhizaini yetransformer haingoonekwi chete nehuwandu hwematenderedzwa asiwo nechinhu chiri pakati uye nzvimbo yekumonera. Chinhu chiri pakati chinofanira kunge chine mukana wakakwira kuti chifambise simba remagineti zvinobudirira, kazhinji uchishandisa silicon steel kana ferrite. Izvi zvinoderedza hysteresis uye kurasikirwa kwe eddy current mutransformer.
Pamusoro pezvo, magadzirirwo epakati anogona kusiyana, akadai seC, E, kana toroidal cores. Sarudzo iyi yakavakirwa pakushanda zvakanaka uye mashandisirwo. Semuenzaniso, ma transformer etoroidal anopa kushanda kwakanyanya uye kudonha kwemvura kwakaderera asi kazhinji anodhura kugadzira.
Mashandisirwo eTransformer muhupenyu hwezuva nezuva
Matransformer haasi emagetsi chete. Nhamba iri kuramba ichikwira yekushandiswa kwezuva nezuva inoenderana nehunyanzvi hwema inductor nema transformer. Mafoni, materevhizheni, nema adaptor ekuchaja ese anoshandisa ma mini transformer.
Mumunda wekutaurirana, ma transformer anoshandiswa muRF circuits uye impedance coupling.
Chimwe chinhu chinonakidza chiri mukushandiswa kwemishonga, semuenzaniso, michina yeMRI inoshandisa ma transformer akakosha kugadzira simba remagineti rakasimba rinodiwa pakufungidzira muviri wemunhu.
Mhedziso
Kupinza magetsi nematransformer ipfungwa mbiri huru dzakakosha muinjiniya yemagetsi. Kupinza magetsi kunoita basa rakakosha mukuchengetedza simba uye kudzora magetsi, nepo matransformer achibvumira kugadziriswa uye kutarisirwa kwemagetsi nemagetsi emagetsi kune akasiyana mashandisirwo. Nekunzwisisa kwakakodzera uye kushandiswa, pfungwa idzi mbiri dzinobatsira mukushanda zvakanaka kwemagetsi, kugoverwa kwesimba zvinobudirira, uye kuvandudzwa kwezvinhu zvitsva muminda yakasiyana-siyana yetekinoroji. Pasina ivo, kufambira mberi kwemazuva ano mutekinoroji yemagetsi kungave kusiri padanho razvino.
