Igishushanyo mbonera cya EMI muyunguruzi yo gutanga amashanyarazi
Akayunguruzo ka EMI karasabwa kurinda ibikoresho by'amashanyarazi kutabangamira amashanyarazi (EMI).Gushungura gushushanya no guhitamo biterwa namabwiriza ya EMI, kode yamashanyarazi, nibindi bisabwa.Mu bihe byinshi, ibisanzwe hanze-ya-muyunguruzi muyunguruzi bizaba bihagije kuri porogaramu, ariko mubihe byinshi, igisubizo cya EMI cyungurura igisubizo kiba nkenerwa kugirango uhuze ibipimo byihariye.
Impamvu ushobora gukenera igishushanyo mboneraEMI AkayunguruzoIgisubizo
Ingaruka zo kwivanga kwa electromagnetic ziratandukanye cyane.Rimwe na rimwe, EMI birababaje gusa bitera guhagarika.Ariko, mubikorwa bikomeye nkubuvuzi nigisirikare, ibibazo nkibi birashobora kwica.
Hariho uburyo bubiri bwingenzi bwo gukwirakwiza EMI - imiyoboro n'imirasire.EMI ikorwa ikwirakwiza binyuze mumigozi nkumurongo wamashanyarazi, insinga, numurongo wibimenyetso.Imivurungano ikabije igenda mu kirere ituruka ahantu nk'ibikoresho by'amashanyarazi, moteri, ibikoresho by'amashanyarazi, terefone ngendanwa n'ibikoresho byohereza radiyo.
EMI ibaho mugihe ibimenyetso byurusaku rwinshi rwatewe namashanyarazi cyangwa ibyuma bya elegitoronike bihagarika imikorere yibikoresho bya elegitoroniki.Kubikoresho bitanga amajwi nkabavuga, ibi birashobora kubyara static cyangwa guturika.Ibindi bicuruzwa bya elegitoronike birashobora guhura nibibazo, imikorere mibi cyangwa amakosa.
Nubwo imirasire ya electromagnetique ishobora kubangamira imikorere yumuzunguruko wa elegitoroniki, irashobora kandi gutuma ibikoresho binanirwa kubahiriza amabwiriza ya EMI.Niba igikoresho kibabajwe na radiyo yumurongo cyangwa ikananirwa kwipimisha EMI, hasabwa akayunguruzo kugirango hagabanuke intambamyi no kuzana igikoresho.
Guhuza amashanyarazi (EMC) injeniyeri bagerageza kugabanya guhagarika no kunanirwa biterwa n’imivurungano yakozwe kandi ikwirakwizwa.
Mubihe byinshi, gukumira kwivanga ni ngombwa-kureba umurimo.Kurugero, niba ibicuruzwa bigurishijwe mumuryango w’ubumwe bw’ibihugu by’Uburayi, bigomba kubahiriza Amabwiriza ya EMC 89/336 / EEC, bisaba ko ibikoresho bigabanywa mu byuka kandi bikarindwa kwivanga hanze.Muri Amerika, hariho ubucuruzi (FCC Igice cya 15 na 18) nibipimo bya gisirikare bisaba kubahiriza EMI bisa.
Mubihe byinshi, nubwo Amerika, EU, namategeko mpuzamahanga ya EMC bidakurikizwa, ibikoresho birashobora gusaba filtri ya EMI kugirango ibarinde urusaku.Nigute wahitamo EMI muyunguruzi biterwa nuburyo butandukanye bwo gutekereza nkibiriho, voltage, inshuro, umwanya, guhuza hamwe nibisabwa cyane gutakaza igihombo.
Kubisabwa byinshi, ibicuruzwa bisanzwe birashobora kuba byujuje ibyashushanyo, ariko niba ibicuruzwa bisanzwe bidashobora kuzuza ibisabwa bikenewe, igishushanyo cyihariye kirasabwa
Muri rusange, urusaku ruke rwurusaku rugaragazwa no kwivanga kwakozwe (guhungabana), kandi akayunguruzo k'urusaku ahanini gashingira ku reaction ya inductive ya coil cole kugirango itange urusaku.Mugihe cyo hejuru cyurusaku rwinshi, imbaraga zurusaku zikorwa zinjizwa nuburinganire bungana na coil coke hanyuma ikarengerwa nubushobozi bwagabanijwe.Muri iki gihe, guhagarika imirase bihinduka uburyo nyamukuru bwo kwivanga.
Ihungabana ry'imirasire itera urusaku rw'ibice byegeranye kandi bikayobora, ibyo bikaba bishobora gutera umuzunguruko kwizunguruka mu bihe bikomeye, ibyo bikaba bigaragara cyane mugihe cyo guteranya ibice bito kandi binini cyane.Ibikoresho byinshi birwanya EMI byinjizwa mumuzunguruko nka pass-pass yo kuyungurura kugirango ihagarike cyangwa ikurura urusaku.Akayunguruzo gacibwa inshuro fcn irashobora gushushanywa cyangwa guhitamo ukurikije urusaku kugirango uhagarike.
Turabizi ko urusaku rwurusaku rwinjijwe mumuzunguruko nkudahuza urusaku, kandi imikorere yarwo ni uguhuza cyane urusaku hejuru yumurongo wikimenyetso.Ukoresheje igitekerezo cyurusaku rudahuye, uruhare rwiyungurura rushobora kumvikana gutya: binyuze muyungurura urusaku, urusaku rushobora kugabanya urusaku rw’urusaku bitewe n’igabanywa rya voltage (attenuation), cyangwa gukuramo imbaraga z’urusaku bitewe n’ibitekerezo byinshi, cyangwa gusenya parasitike kubera impinduka zicyiciro.imiterere yinyeganyeza, bityo bitezimbere urusaku rwumuzunguruko.
Tugomba kandi kwitondera ibibazo bikurikira mugihe dushushanya no gukoresha ibikoresho birwanya EMI:
1. Mbere ya byose, tugomba gusobanukirwa n'ibidukikije bya electroniki kandi tugahitamo intera yumvikana;
2. Urebye niba hari DC cyangwa AC ikomeye mumuzunguruko aho akayunguruzo k'urusaku gaherereye, kugirango wirinde intandaro yigikoresho kutuzura no kunanirwa;
3. Sobanukirwa neza ubunini na kamere ya impedance mbere na nyuma yo kwinjizwa mumuzunguruko kugirango ugere ku rusaku rudahuye.Inzitizi ya coke coil muri rusange ni 30-500Ω, ikaba ikwiriye gukoreshwa munsi yimbaraga nkeya hamwe no kwikorera imitwaro;
4. Witondere kandi inzira yambukiranya hagati yubushobozi bwagabanijwe hamwe nibice byegeranye hamwe ninsinga;
5. Byongeye kandi, witondere kugenzura izamuka ryubushyuhe bwibikoresho, muri rusange bitarenze 60 ° C.
Ibyavuzwe haruguru nuburyo bwo gushushanya imbaraga za EMI filteri DOREXS yasangiye nawe uyumunsi, nizere ko izagufasha!
DOREXSUmuyobozi w'inganda EMI
Niba ukeneye kurinda EMI neza, DOREXS itanga EMI iramba kandi yizewe kuri buri porogaramu.Akayunguruzo kacu gakenewe mubikorwa byumwuga mubisirikare nubuvuzi, kimwe no gutura no mu nganda.Kubisabwa bisaba igisubizo cyihariye, itsinda ryacu ryumwuga rirashobora gushushanya EMI muyunguruzi kugirango wuzuze ibisabwa byihariye.
