FAQs

Kodi zosefera ndi zotani?

(1) fyuluta yotsika

Kuchokera pa 0 mpaka F2, mawonekedwe a amplitude-frequency ndi athyathyathya, omwe amatha kupangitsa kuti magawo omwe ali pansi pa F2 adutse mosavutikira, pomwe apamwamba kuposa F2 amachepetsedwa kwambiri.

(2) fyuluta yapamwamba

Mosiyana ndi kusefa kwapansi, mawonekedwe ake amplitude-frequency amakhala athyathyathya kuchokera pafupipafupi F1 mpaka infinity.Zimalola kuti ma frequency a siginecha pamwamba pa F1 adutse mosavutikira, pomwe omwe ali pansi pa F1 adzachepetsedwa kwambiri.

(3) gulu pass fyuluta

Chiphaso chake chili pakati pa F1 ndi F2.Zimalola kuti zigawo zafupipafupi za sigino zikhale zapamwamba kuposa F1 komanso zotsika kuposa F2 kuti zidutse mosavutikira, pomwe zida zina zimachepetsedwa.

(4) gulu loyimitsa fyuluta

Mosiyana ndi kusefa kwa bandpass, gulu loyimitsa lili pakati pa ma frequency F1 ndi F2.Imachepetsera ma frequency a siginecha apamwamba kuposa F1 komanso otsika kuposa F2, ndipo magawo ena onse amadutsa pafupifupi mosayembekezereka.

Kodi fyuluta yamagetsi ya EMI ndi chiyani?

Electromagnetic interference (EMI) fyuluta yamagetsi ndi chipangizo chosagwira ntchito chopangidwa ndi inductance ndi capacitance.Imakhala ngati zosefera ziwiri zotsika, imodzi imalepheretsa kusokoneza wamba ndipo inayo imachepetsa kusokoneza kwamitundu yosiyanasiyana.Imachepetsera mphamvu ya rf mu bandi yoyimitsa (nthawi zambiri imakhala yopitilira 10KHz) ndikulola kuti ma frequency amphamvu adutse ndikutsitsa pang'ono kapena osatsitsa.Zosefera zamagetsi za EMI ndiye kusankha koyamba kwa mainjiniya opanga zamagetsi kuti aziwongolera zomwe zimayendetsedwa ndikuwotchedwa EMI.

Kodi mfundo yogwirira ntchito ya EMI mphamvu fyuluta ndi chiyani?

(A) Pogwiritsa ntchito mawonekedwe a capacitor omwe amadutsa ma frequency apamwamba komanso kudzipatula kwafupipafupi, kusokoneza kwanthawi yayitali kwa waya wamoyo ndi waya wosalowerera kumalowetsedwa mu waya wapansi (njira wamba), kapena kusokoneza kwanthawi yayitali kwa waya wamoyo kumayambitsidwa. mu waya wosalowerera (njira yosiyana);

(B) Onetsani kusokoneza kwapafupipafupi komwe kumabwereranso ku gwero losokoneza pogwiritsa ntchito mawonekedwe a impedance ya coil inductor;

Kodi ziyenera kutsatiridwa ndi chiyani pakuyika fyuluta?

Kuti muchepetse kukana kwapansi, fyulutayo iyenera kuyikidwa pazitsulo zoyendetsera zitsulo kapena kulumikizidwa ndi malo ozungulira pafupi ndi malo otchinga pansi kuti mupewe kutsekeka kwakukulu komwe kumachitika chifukwa cha mawaya ocheperako.

Kodi kusankha mphamvu fyuluta?

Zolozera zingapo ziyenera kuganiziridwa posankha fyuluta ya mzere wamagetsi.Yoyamba idavotera ma voliyumu / ovotera pakali pano, kutsatiridwa ndi kutayika kwa kuyika, kutayikira kwapano (dc mphamvu fyuluta samaganizira kukula kwa kutayikira kwapano), kukula kwake, ndipo pamapeto pake ndiye kuyesa kwamagetsi.Popeza kuti mkati mwa fyuluta nthawi zambiri kumakhala poto, mawonekedwe a chilengedwe sizovuta kwambiri.Komabe, mawonekedwe a kutentha kwa zinthu zophika ndi fyuluta capacitor amakhala ndi chikoka pazachilengedwe za fyuluta yamagetsi.

Kuchuluka kwa fyuluta kumatsimikiziridwa makamaka ndi inductance mu dera la fyuluta.Kuchuluka kwa voliyumu ya inductance koyilo, kumapangitsanso kuchuluka kwa fyuluta.
