Kuki abakoresha inductors nabo bafite ibisabwa ku ntera y'umutekano?

Umwimerere: Umucyo w'ibikoresho

Akamaro k'ibanze k'uburyo bwo gukwirakwiza amashanyarazi mu miyoboro y'amashanyarazi ni ugushungura, cyane cyane mu gutunganya ibimenyetso. Kuki hari ibisabwa mu ntera y'umutekano mu gihe cyo gutanga icyemezo? Iyi nkuru izatanga ibisubizo by'ingenzi kuri iki kibazo.

Mu by’ukuri, ku bijyanye n’imiyoboro rusange, nta tegeko risobanutse neza rigenga intera y’umutekano ya inductors. Zigomba gusa kuzuza ibisabwa by’ibanze byo gukingira amashanyarazi, kandi ibicuruzwa ntibizahagarika uruziga nyuma y’igihe kirekire.
Iyo tugerageza inductors, akenshi tugerageza imbaraga z'amashanyarazi zirwanya windings cyangwa windings ku mpande za rukuruzi, akenshi hafi 500VAC.

Ariko, iyo inductors zikoreshejwe mu miterere y’amashanyarazi afite ingufu nyinshi, bizaba bitandukanye. Mu miterere y’amashanyarazi afite ingufu nyinshi, intera iri hagati y’ingufu zikoresha ingufu akenshi igomba kubahiriza amahame agenga aho amashanyarazi anyura n’intera yo gucikamo ibice kugira ngo hirindwe ko amashanyarazi asohoka cyangwa ngo acike.
Dukurikije ibipimo bya IEC60950, urwego rw'amashanyarazi atandukanye ruhura n'intera ntoya zitandukanye. Iyo umurongo wa voltage wa 400V udashyizwemo, icyuho cy'amashanyarazi hagati y'udupira twa inductor kigomba kuba ≥ 6.4mm.

Ku bijyanye n'intera yo gukurura, kuri za circuits za 220V, intera yo gukurura ya substrate ya FR4 igomba kuba ≥ 4.0mm. Ku bikoresho bifite voltage nyinshi, nk'ibiri iruhande rwa transformer nyamukuru y'amashanyarazi ahinduranya, intera yo gukurura ingufu irakenewe ≥ 8.0mm.
Iyo ubushyuhe bw'imikorere ya inductor buri hejuru ugereranyije, intera y'umutekano ishobora kongerwa neza kugira ngo ihuze no gusaza kw'ibikoresho byo gukingira biterwa no gukoreshwa igihe kirekire kwa inductor.

Mu gihe cyo gushushanya urujya n'uruza rw'amashanyarazi, niba intera yo gukurura idahagije, gupfundikanya bishobora no gukoreshwa kugira ngo huzuzwe ibisabwa. Mu guhitamo ibikoresho bya inductor, ni ngombwa gukoresha skeleton idashya kandi idacana umuriro, insinga ifite enamel idashyuha cyane, na kaseti yemewe n'umutekano kugira ngo harebwe ko hubahirizwa amahame n'ibisabwa by'umutekano.
Muri rusange, intera y'umutekano ku ba inductors ni ukwirinda ingaruka mbi z'umutekano ziterwa no kwangirika kw'amashanyarazi, kuva amazi mu kirere no kunanirwa k'ubushyuhe. Ibi bishobora kwerekeza ku mahame nka IEC 60950 na UL 60950, kandi bigakorwa ku buryo bwuzuye hashingiwe ku rugero rw'amashanyarazi, aho akazi gakorerwa, n'imiterere y'ibikoresho kugira ngo habeho isuzuma n'icyemezo cy'uko ibintu byakozwe.
