Waba uzi igitera kumeneka mumashanyarazi yumuriro?

AmashanyaraziIkirundo cyo kumena ikirundo muri rusange kigabanijwemo ubwoko bune, aribwo: igice cya semiconductor igice gisohora amashanyarazi, amashanyarazi yamenetse, capacitor yamenetse hamwe na filteri yamenetse.

1. Kumeneka kw'ibice bya semiconductor

Umuyoboro muto cyane unyura muri PN ihuza iyo yaciwe.DS ibogamye imbere, GS irabogamye, kandi nyuma yo gufungura umuyoboro uyobora, umuyoboro uzaturuka kuri D ujya kuri S. Ariko mubyukuri, kubera kubaho kwa electroni yubusa, electroni yubusa ifatanye na SIO2 na N +, bikavamo kumeneka ikigezweho cya DS.

2. Umuyoboro w'amashanyarazi

Kugirango ugabanye kwivanga mumashanyarazi atangwa, ukurikije urwego rwigihugu, hagomba gutangwa akayunguruzo ka EMI.Bitewe nubusabane bwumuzunguruko wa EMI, hari akantu gato kamanuka kubutaka nyuma yo guhinduranya amashanyarazi ahujwe numuyoboro, aribwo buryo bwo kumeneka.Niba idafite ishingiro, igikonoshwa cya mudasobwa kizaba gifite voltage ya volt 110 hasi, kandi bizumva bitagenze neza iyo ubikozeho amaboko, kandi bizagira ingaruka no kumurimo wa mudasobwa.

3. Umuyoboro wa capacitori

Ubushobozi bwa capacitor ntibushobora kuba butayobora;mugihe ingufu za DC zashyizwe kuri capacitor, capacitor izaba ifite umuyonga.Niba imiyoboro yamenetse ari nini cyane, capacitor yangizwa nubushyuhe.Usibye ubushobozi bwa electrolytike, imiyoboro yameneka yizindi capacator ni nto cyane, bityo ibipimo byo kurwanya insulasiyo bikoreshwa muguhagararira imikorere yabyo, mugihe capacitori ya electrolytike ifite imiyoboro minini yamenetse, bityo imiyoboro yameneka ikoreshwa kugirango igaragaze imikorere yabyo. ku bushobozi).Iyo igipimo cya DC gikora voltage ikoreshwa kuri capacitor, bizagaragara ko ihinduka ryumuriro wumuriro ritangira kuba rinini, kandi rigabanuka nigihe.Iyo igeze ku giciro cyanyuma, igera kuri leta ihagaze neza.Agaciro kanyuma kanyuma bita leakage current.i = kcu (ua);aho k ni imyanda ihoraho, igice ni μa (v: μf)

4. Shungura akayunguruzo

Amashanyarazi yamenetse yamashanyarazi asobanurwa nku: umuyaga uva muyungurura amazu kugeza kumpera iyo ari yo yose ya AC yinjira munsi ya voltage yagenwe.Niba ibyambu byose byayunguruzo bitandukanijwe rwose mumazu, agaciro k'umuyagankuba uterwa ahanini biterwa n'umuyoboro w'amazi usanzwe wa capacitor CY, ni ukuvuga, ahanini biterwa n'ubushobozi bwa CY.Bitewe nubunini bwimyanda yamenetse ya filteri, irimo umutekano wumuntu ku giti cye, ibihugu byose kwisi bifite amahame akomeye kuri yo.Kumashanyarazi ya 220V / 50Hz, amashanyarazi ava mumashanyarazi asabwa muri rusange kuba munsi ya 1mA.
