Kuteteza mkati ndi kunja kwa osintha pafupipafupi kwambiri

Kutetezedwa koyipa sikumakhudza kwenikweni magwiridwe antchito a ma frequency apamwamba, koma kumayambitsa kusokoneza kwakukulu kwa zida zamagetsi zozungulira. Izi ndi zomwe timatcha nthawi zambiri EMI. Ndi kupita patsogolo kosalekeza kwaukadaulo, pakhala kufunikira kwa zosintha zama frequency apamwamba zomwe zimagwira bwino ntchito komanso kuchepetsa kusokoneza kwa electromagnetic (EMI).

Lero, tiyeni tiyambe kukambirana za chitetezo chamkati cha ma transformer apamwamba kwambiri.

Choyamba, pokhomerera mafunde otetezedwa mkati mwa thiransifoma, waya awiriwa sayenera kukhala wandiweyani kwambiri kuti apewe kutayikira kwa inductance komanso kusalumikizana bwino. Chiwerengero chenicheni cha matembenuzidwe ayenera kuikidwa mwaukhondo kuti mudzaze m'lifupi phukusi la waya popanda stacking. Malekezero osweka a mawaya amayenera kukwiriridwa kwathunthu mu phukusi la waya kuti apewe kuwonekera komanso zovuta zomwe zingachitike.

Ena, pogwiritsira ntchito zojambulazo za mkuwa monga zokhotakhota mkati mwa thiransifoma, m'lifupi mwake lonse la zojambula zamkuwa ziyenera kukhala zochepa pang'ono kusiyana ndi m'lifupi mwake. Ngati ndi yayikulu kwambiri, ipangitsa kuti mbali zonse ziwiri za zojambula zamkuwa zizipindika, zomwe zimabweretsa kutulutsa kotulutsa komanso kusagawa bwino. Palinso chiopsezo cholephera kupirira mayesero amagetsi; Choncho, chidwi ayenera kuperekedwa kupanga solder olowa lathyathyathya popanda mfundo lakuthwa.

Ngati mukugwiritsa ntchito njira yokhotakhota masangweji, kuphimba kwathunthu pakati pa mafunde a pulayimale ndi achiwiri sikofunikira pakutchingira kwamkati. Cholinga chachikulu cha chitetezo chamkati ndikuwongolera zizindikiro za data zosokoneza wamba kuchokera kumbali yoyambirira kubwereranso m'malo otetezedwa kuti tipewe mavuto a EMI kumapeto.

Tsopano tiyeni tikambirane za kunja chitetezo kwama transfoma apamwamba kwambiri.

Momwemonso, mutha kugwiritsa ntchito njira yokulunga waya yamkuwa.
Mukaphatikiza maginito pachimake, kulungani 5-10 mozungulira ndi waya wamkuwa womwewo m'mimba mwake motsatira njira ya maginito musanayambe kuyika zikhomo. Izi zimachepetsa bwino ma radiation a electromagnetic opangidwa ndi ma transfoma othamanga kwambiri.

Mukamagwiritsa ntchito zojambulazo za mkuwa ngati chishango m'malo mwake , m'lifupi mwake mumafunikanso kuchepetsedwa pang'ono poyerekeza ndi kukula kwa maginito core. Komabe, ndikofunikira kuti zojambulazo zakunja zokulungidwa zamkuwa zikhale zotsekedwa kwathunthu, ndipo makamaka zimasindikizidwa ndi solder potseka. Ngati chojambula chamkuwa chodzimatirira chikugwiritsidwa ntchito, chidwi chapadera chiyenera kuperekedwanso pakupirira vuto lamagetsi chifukwa nthawi zambiri pomwe mphamvu yamagetsi imalephera chifukwa cha kutchinjiriza koyipa pakati pa maginito pachimake ndi ma windings.

Pakakhala kutayikira kwa maginito amagetsi akuwotchera danga lakunja, malinga ndi mfundo ya kulowetsedwa kwa ma elekitiroma, pamakhala kupangitsidwa kwamakono mkati mwa wosanjikiza wakunja wotchinga, kutulutsa gawo loyang'anana ndi maginito amagetsi omwe amalepheretsa kukhudzidwa komwe kumabwera chifukwa cha kutayikira kwa maginito amagetsi kuchokera pamagetsi othamanga kwambiri, motero kuonetsetsa kuti palibe dziko lakunja .

Mwa kukhathamiritsa kasinthidwe ka mapindikidwe ndi kugwiritsa ntchito zida zapadera zotchingira,opanga ma thiransifomaakhoza kuchepetsa kulumikiza capacitive pakati pa mchenga wokhotakhota kuchepetsa kuopsa kwa kupanga EMI mkati mwa transformer.Izi zimathandizira kugwira ntchito ndi kudalirika kwa osintha pafupipafupi, kuwapanga kukhala oyenera ntchito zosiyanasiyana kuphatikizapo magetsi, zida zoyankhulirana, makina opanga mafakitale, zipangizo zamankhwala, ndi zamagetsi zakuthambo."

Zikomo powerenga mpaka pano ndikukhala ndi tsiku labwino!

Takulandilani kuyitanitsa malonda athu, timathandizira maoda a OEM/ODM, chiyembekezo chokhulupirika chokhala bwenzi lanu.

Zomwe zili m'nkhaniyi ndizomwe zimangogwiritsidwa ntchito.
