Munyaya yeinjiniya yemagetsi nekugoverwa kwesimba, kusarudzwa kwezvinhu zvepakati zvematransformer nema inductors kunoita basa guru mukuona kushanda zvakanaka uye mashandiro emidziyo. Sarudzo mbiri dzakakurumbira dzezvinhu zvepakati i amorphous core ne nanocrystalline core, imwe neimwe ichipa hunhu hwakasiyana uye zvakanakira. Muchinyorwa chino, tichaongorora hunhu hwe amorphous core ne nanocrystalline core, uye tichaongorora musiyano uripo pakati pezviviri izvi.
Chii chinonzi Amorphous Core?
An musimboti usina chimiroimhando yezvinhu zvemagineti zvine maatomu asingaonekwe sekristaro. Kurongeka uku kwakasiyana kunoita kuti maatomu asina chimiro (amorphous cores) ave nehunhu hwawo hwakasiyana, kusanganisira kurasikirwa kwakaderera kwepakati, kupenya kwakanyanya, uye hunhu hwakanaka hwemagineti. Chinhu chinoshandiswa zvakanyanya kumaamorphous cores isimbi, inowanzo kuve nezvinhu zvakaita sesimbi, boron, silicon, uye phosphorus.
Kusaita makristaro kwemakori asina chimiro chekristaro kunoita kuti maatomu arongeke zvisina kurongeka, izvo zvinodzivirira kuumbwa kwemadomeni emagineti uye zvinoderedza kurasikirwa kwemagetsi e-eddy. Izvi zvinoita kuti makori asina chimiro chekristaro ashande zvakanaka pakushandiswa uko kurasikirwa nesimba shoma uye kubvumidzwa kwakanyanya kwemagineti kwakakosha, senge mumatransformer emagetsi uye mainductors ane frequency yakakwira.
Makori eAmorphous anogadzirwa achishandisa nzira yekukurumidza kusimbisa, uko alloy yakanyungudutswa inodzimwa nekukurumidza kudzivirira kuumbwa kwezvimiro zvekristaro. Maitiro aya anoguma nechimiro chemaatomu chisina kurongeka kwenguva refu, zvichiita kuti chinhu chacho chive nehunhu hwacho hwakasiyana.
Chii chinonzi Nanocrystalline Core?
Kune rumwe rutivi, nanocrystalline core rudzi rwemagnetic core material ine nanometer-size crystalline grains iri mu amorphous matrix. Iyi dual-phase structure inobatanidza mabhenefiti e crystalline ne amorphous materials, zvichikonzera magnetic properties yakanaka uye high saturation flux density.
Nanocrystalline coreszvinowanzogadzirwa nemusanganiswa wesimbi, nickel, uye cobalt, pamwe chete nezvimwe zvinhu zvidiki zvakaita semhangura nemolybdenum. Maumbirwo e nanocrystalline anopa simba remagineti rakakwira, simba rakaderera, uye kugadzikana kwekupisa kwakanyanya, zvichiita kuti ive yakakodzera kushandiswa nesimba guru uye ma transformer ane frequency yakakwira.
Musiyano uripo pakati peAmorphous Core neNanocrystalline Core
Musiyano mukuru uripo pakati pemakori asina chimiro uye makori ane makristaro ari mumaumbirwo awo eatomu uye hunhu hwemagineti hunobuda. Kunyange zvazvo makori asina chimiro aine maumbirwo asina chimiro, makori ane makristaro anoratidza maumbirwo ane zvikamu zviviri ane makristaro akakura se nanometer mukati me matrix asina chimiro.
Panyaya yehunhu hwemagineti,mativi asina chimiroAnozivikanwa nekurasikirwa kwawo nepakati uye kupenya kwakanyanya, zvichiita kuti akwanise kushandiswa uko kushandiswa kwesimba kwakanyanya. Kune rumwe rutivi, nanocrystalline cores inopa huwandu hwakawanda hwe saturation flux density uye kugadzikana kwakanyanya kwekupisa, zvichiita kuti akwanise kushandiswa ne high-power uye high-frequency applications.
Mumwe musiyano mukuru imaitiro ekugadzira. Makori eAmorphous anogadzirwa kuburikidza nekusimba nekukurumidza, izvo zvinosanganisira kudzima alloy yakanyungudutswa nekukurumidza kudzivirira kuumbwa kwekristalline. Kusiyana neizvi, makori eNanocrystalline anowanzo kugadzirwa kuburikidza nekudzvanya uye kudzora makristaro eAmorphous ribbons, zvichikonzera kuumbwa kwezviyo zvekristalline zvakakura se nanometer mukati mechinhu chacho.
Zvaunofanira Kufunga Nezvekushandisa
Pakusarudza pakati pema cores asina chimiro uye ma nanocrystalline cores ekushandisa kwakati, zvinhu zvakawanda zvinofanirwa kutariswa. Kune ma application anonyanya kukosha pakurasikirwa nesimba shoma uye kushanda zvakanaka, senge muma power distribution transformers uye high-frequency inductors, ma cores asina chimiro anowanzo sarudzwa. Kurasikirwa kwavo nepakati pasi uye kupindira kwakanyanya kunoita kuti akwanise kushandiswa aya, zvichibatsira mukuchengetedza simba rese uye kuvandudza mashandiro.
Kune rumwe rutivi, kune zvishandiso zvinoda huwandu hwakawanda hwemvura inoyerera, kugadzikana kwakanyanya kwekupisa, uye kugona kubata simba guru, nanocrystalline cores dzakakodzera zvakanyanya. Hunhu uhwu hunoita kuti nanocrystalline cores ive yakakodzera kune ma transformer ane simba guru, ma inverter application, uye magetsi ane frequency yakawanda, uko kugona kubata magnetic flux densities uye kuchengetedza kugadzikana pasi pemamiriro akasiyana ekushanda kwakakosha.
Mukupedzisa, ese ari maviri macore asina chimiro uye macore e-nanocrystalline ane zvakanakira zvakasiyana uye akagadzirirwa zvinodiwa zvekushandisa. Kunzwisisa musiyano uripo muchimiro chawo chemaatomu, hunhu hwemagineti, uye maitiro ekugadzira kwakakosha pakuita sarudzo dzakarongeka pakusarudza zvinhu zvepakati zvematransformer ne-inductors. Nekushandisa hunhu hwakasiyana hwechinhu chimwe nechimwe, mainjiniya nevagadziri vanogona kugadzirisa mashandiro uye kushanda zvakanaka kwemasisitimu avo ekugovera nekushandura simba, zvichizopedzisira zvabatsira mukufambira mberi mukushanda zvakanaka kwesimba uye matekinoroji esimba anogarika.
