Njira yopangira EMI fyuluta yamagetsi

Zosefera za EMI zimafunikira kuteteza zida zamagetsi ku kusokonezedwa ndi electromagnetic (EMI).Kapangidwe kazosefera ndi kusankha kumadalira malamulo a EMI, ma code amagetsi, ndi zina zofunika pakupanga.Nthawi zambiri, zosefera zokhazikika pa alumali zimakwanira kugwiritsa ntchito, koma nthawi zambiri, njira yosinthira ya EMI imakhala yofunikira kuti ikwaniritse magawo enaake.

Chifukwa Chake Mungafunikire Kupanga MwamakondaEMI FyulutaYankho

Zotsatira za kusokoneza kwa electromagnetic zimasiyana mosiyanasiyana.Nthawi zina, EMI imangokhala zokhumudwitsa zomwe zimayambitsa zosokoneza.Komabe, m'machitidwe ovuta monga azachipatala ndi ankhondo, mavuto oterowo amatha kupha.

Pali njira ziwiri zazikulu zofalitsira EMI - conduction ndi radiation.EMI yoyendetsedwa imafalikira kudzera mu zingwe monga zingwe zamagetsi, mawaya, ndi ma siginecha.Zosokoneza zowulutsa zimadutsa mumlengalenga kuchokera kuzinthu zamagetsi, ma mota, magetsi, mafoni am'manja ndi zida zotumizira mawayilesi.

EMI imachitika pamene ma siwichi amphamvu kwambiri opangidwa ndi ma switch amagetsi kapena zamagetsi amasokoneza magwiridwe antchito a zida zamagetsi.Pazida zopangira mawu monga okamba, izi zimatha kutulutsa mawu osasunthika kapena osweka.Zinthu zina zamagetsi zimatha kukumana ndi zosokoneza, zolakwika kapena zolakwika.

Ngakhale ma radiation a electromagnetic amatha kusokoneza magwiridwe antchito amagetsi, angayambitsenso zida kulephera kutsatira malamulo a EMI.Ngati chipangizo chikuvutitsidwa ndi kusokonezedwa kwa ma radio pafupipafupi kapena chikulephera kuyezetsa kwa EMI, fyuluta imafunika kuchepetsa kusokoneza ndikupangitsa chipangizocho kuti chizitsatira.

Kugwirizana kwa Electromagnetic (Mtengo wa EMC) Akatswiri amayesa kuchepetsa zosokoneza ndi zolephera zomwe zimachitika chifukwa cha kusokoneza komwe kumachitika komanso kutulutsa ndi mpweya.

Nthawi zambiri, kuletsa kusokoneza ndi ntchito yofunika kuwona.Mwachitsanzo, ngati chinthu chikugulitsidwa ku European Union, chiyenera kutsatira EMC Directive 89/336/EEC, yomwe imafuna kuti zipangizo zichepetse mpweya ndi kutetezedwa ku zosokoneza zakunja.Ku US, pali zamalonda (FCC Part 15 ndi 18) ndi miyezo yankhondo yomwe imafuna kutsata kwa EMI kofanana.

Nthawi zambiri, ngakhale malamulo a US, EU, ndi mayiko a EMC sagwira ntchito, zida zitha kufunikilabe zosefera za EMI kuti zitetezedwe kumadera aphokoso.Momwe mungasankhire fyuluta ya EMI zimadalira malingaliro angapo apangidwe monga apano, magetsi, ma frequency, malo, kulumikizana komanso kutayika kofunikira kofunikira kwambiri.

Pazinthu zambiri, zinthu zomwe zimagwiritsidwa ntchito nthawi zonse zimatha kukwaniritsa zofunikira, koma ngati zinthu zomwe zili zokhazikika sizingakwaniritse zomwe zimafunikira, mapangidwe amafunikira.

Nthawi zambiri, kutsika kwaphokoso kumawonetsedwa ngati kusokoneza komwe kumachitika (kusokoneza), ndipo zosefera zaphokoso zimadalira momwe ma coil amachitira kuti athetsere phokoso.Pamapeto apamwamba a mafupipafupi a phokoso, mphamvu ya phokoso imatengedwa ndi kukana kofanana kwa koyilo yachitsulo ndikudutsa mphamvu yogawidwa.Panthawi imeneyi, kusokonezeka kwa ma radiation kumakhala mtundu waukulu wa kusokoneza.

Kusokonezeka kwa ma radiation kumayambitsa phokoso la phokoso pazigawo zapafupi ndi kutsogolera, zomwe zingayambitse kudzikonda kwa dera pazifukwa zazikulu, zomwe zimakhala zodziwika kwambiri pamagulu ang'onoang'ono ndi apamwamba kwambiri.Zida zambiri zotsutsana ndi EMI zimayikidwa m'mabwalo ngati zosefera zotsika pang'ono kuti zithetse kapena kusokoneza phokoso.Zosefera zodulira pafupipafupi fcn zitha kupangidwa kapena kusankhidwa molingana ndi ma frequency aphokoso omwe amayenera kuponderezedwa.

Tikudziwa kuti fyuluta yaphokoso imayikidwa mu dera ngati phokoso losokoneza, ndipo ntchito yake ndikusokoneza kwambiri phokoso pamwamba pa mafupipafupi a chizindikiro.Pogwiritsa ntchito lingaliro la kusokonekera kwa phokoso, gawo la fyuluta limatha kumveka motere: kudzera pa fyuluta yaphokoso, phokoso limatha kuchepetsa kuchuluka kwa phokoso chifukwa cha kugawikana kwamagetsi (kuchepetsa), kapena kuyamwa mphamvu yaphokoso chifukwa chowunikira kangapo, kapena kuwononga. parasitic chifukwa cha kusintha kwa gawo la njira.oscillation zinthu, potero kusintha phokoso malire a dera.

Tiyeneranso kulabadira zotsatirazi popanga ndi kugwiritsa ntchito zida zotsutsana ndi EMI:

1. Choyamba, tiyenera kumvetsetsa chilengedwe cha electromagnetic ndikusankha ma frequency oyenerera;

2. Poyang'ana ngati pali DC kapena AC yamphamvu m'dera limene fyuluta yaphokoso ili, kuteteza pakati pa chipangizocho kuti zisakhutitsidwe ndi kulephera;

3. Kumvetsetsa bwino kukula ndi chikhalidwe cha impedance isanayambe kapena itatha kuyika mu dera kuti mukwaniritse kusagwirizana kwa phokoso.The impedance wa koyilo tsamwitsa zambiri 30-500Ω, amene ali oyenera ntchito pansi otsika gwero impedance ndi katundu impedance;

4. Komanso tcherani khutu ku crosstalk inductive pakati pa capacitance yogawidwa ndi zigawo zoyandikana ndi mawaya;

5. Kuphatikiza apo, tcherani khutu pakuwongolera kutentha kwa chipangizocho, nthawi zambiri osapitilira 60 ° C.

Zomwe zili pamwambazi ndi njira yopangira mphamvu ya EMI fyuluta yomwe DOREXS adagawana nanu lero, ndikuyembekeza kuti idzakuthandizani!

DOREXSMtsogoleri wamakampani a EMI

Ngati mukufuna chitetezo chokwanira cha EMI, DOREXS imapereka zosefera zolimba komanso zodalirika za EMI pakugwiritsa ntchito kulikonse.Zosefera zathu ndizoyenera kugwiritsa ntchito akatswiri pantchito zankhondo ndi zamankhwala, komanso zogwiritsidwa ntchito kunyumba ndi mafakitale.Pamapulogalamu omwe amafunikira yankho lokhazikika, gulu lathu la akatswiri litha kupanga fyuluta ya EMI kuti ikwaniritse zomwe mukufuna.

Pokhala ndi zaka 15 zothana ndi vuto lamagetsi, DOREXS ndiwopanga zosefera zapamwamba za EMI zachipatala, zankhondo, komanso zamalonda.Zosefera zathu zonse za EMI zidapangidwa kuti zikwaniritse miyezo yamakampani ndikutsatira malamulo a EMC.Onani zosefera zathu za EMI kapena tumizani zosefera kuti mupeze zosefera zabwino za EMI pazosowa zanu.Kuti mudziwe zambiri za makonda a DOREXS ndi zosefera za EMI, chonde titumizireni.
