Ikhoyili ye-air core
Isakhiwo kanye nokwakheka
Izinto zocingo:ngokuvamile ithusi noma ucingo lwe-aluminium (ukumelana okuphansi, ukuqhutshwa okuphezulu), indawo engaphezulu ingase ibe nesiliva-plated noma ihlanganiswe ngopende wokuvikela.
Indlela yokuphefumula:i-spiral winding (i-single noma i-multi-layer), umumo ungaba yi-cylindrical, flat (ikhoyili ye-PCB) noma indandatho.
Idizayini engenasisekelo:ikhoyili igcwaliswa ngomoya noma izinto ezingezona uzibuthe (ezifana nohlaka lwepulasitiki) ukugwema ukulahleka kwe-hysteresis kanye nomphumela wokugcwala okubangelwa ingqikithi yensimbi.
Amapharamitha angukhiye nokusebenza
I-Inductance:ngaphansi (uma kuqhathaniswa namakhoyili ensimbi), kodwa ingandiswa ngokukhuphula inani lokuphenduka noma indawo yekhoyili.
Isici sekhwalithi (inani le-Q):Inani le-Q liphezulu kumafrikhwensi aphezulu (akukho ukulahleka kwamanje kwe-iron core eddy), ifanele izinhlelo zokusebenza zefrikhwensi yomsakazo (RF).
Amandla asabalalisiwe:Umthamo wokuphenduka kwekhoyili ungase uthinte ukusebenza kwemvamisa ephezulu, futhi isikhala sokujika sidinga ukuthuthukiswa.
Ukumelana:Inqunywa ngezinto zocingo nobude, ukumelana ne-DC (DCR) kuthinta ukusetshenziswa kwamandla.
Izinzuzo kanye nokubi
Izinzuzo:
Ukusebenza okuhle kakhulu kwe-high-frequency: akukho ukulahleka kwe-iron core, kulungele i-RF nesekhethi ye-microwave.
Akukho ukugcwaliswa kazibuthe: inductance ezinzile ngaphansi kwamanje ephezulu, ilungele ukushaya kwenhliziyo nezimo eziguquguqukayo eziphezulu.
I-Lightweight: isakhiwo esilula, isisindo esincane, izindleko eziphansi.
Ububi:
I-inductance ephansi: inani le-inductance lincane kakhulu kunalelo lamakhoyili angumgogodla wensimbi ngevolumu efanayo.
Amandla kazibuthe abuthakathaka: kudinga ukujika okukhulu kwamanje noma ngaphezulu ukuze kukhiqizwe inkambu kazibuthe efanayo.
Izimo zohlelo lokusebenza ezijwayelekile
Amasekhethi aphezulu:
I-RF choke, i-LC resonant circuit, inethiwekhi ehambisana ne-antenna.
Izinzwa nokutholwa:
Izithungatha zensimbi, izinzwa zamanje ezingathinteki (amakhoyili e-Rogowski).
Imishini yezokwelapha:
Amakhoyili wegradient wezinhlelo ze-MRI (ukugwema ukuphazamiseka kazibuthe).
Amandla kagesi:
Ama-transformer amafrikhwensi aphezulu, amakhoyili wokushaja angenantambo (ukugwema ukushisisa kwe-ferrite).
Izinkambu zocwaningo:
Amakhoyili e-Helmholtz (ukukhiqiza amasimu kazibuthe afanayo).
FAQ
A: Siyimboni.
A: Sineminyaka engu-20 yesipiliyoni sokukhiqiza intwasahlobo futhi singakhiqiza izinhlobo eziningi zeziphethu. Ithengiswa ngentengo eshibhile kakhulu.
A: Ngokuvamile izinsuku ezingu-5-10 uma izimpahla zisesitokweni. Izinsuku ezingu-7-15 uma izimpahla zingekho esitokweni, ngobuningi.
