Guhinduranya ingufu nkeya zinganda zinganda

Ibikoresho bitandukanye byo murugo, ingandaGuhindura inshuro, baba bashushanya ubwabo, cyangwa bagasana transformateur yatwitse, bagira uruhare mubice byoroshye kubara, ibitabo kuri formula, nubwo bikomeye, ariko gushyira mubikorwa bigoye, ntabwo byoroshye.Iyi ngingo itangiza impinduka zifatika zifatika zifatika zifatika.

1. Guhitamo icyuma

Ukurikije imbaraga zabo bwite bakeneye guhitamo intangiriro iburyo nintambwe yambere yo guhinduranya transformateur. Niba icyuma (icyuma cya silicon) guhitamo ari kinini cyane, bizatuma habaho kwiyongera mubunini bwa transformateur, igiciro cyo hejuru, ariko icyuma ni gito cyane, bizongera igihombo cya transformateur, mugihe ubushobozi gutwara umutwaro biba ubukene.

Kugirango umenye ingano yibyuma, ikintu cya mbere cyo kubara ingufu nyazo zikoreshwa na transformateur ya kabiri, ihwanye na transformateur ya kabiri ya voltage voltage, igiteranyo cyibicuruzwa biva mumitwaro. Niba ari impinduramatwara yuzuye ikosora, igomba kubarwa nka 1/2 cya transformateur ya kabiri ya voltage. Icyiciro cya kabiri cyingufu zikoreshwa kugirango zifatanye na transformateur ubwayo imbaraga zo gutakaza, ni ukuvuga imbaraga za transformateur imbaraga zigaragara.

Imbaraga rusange zuzunguruka muri 10w munsi ya transformateur, igihombo cyayo cyo gukoresha ingufu za kabiri zirashobora kugera kuri 30 ~ 50% byokoresha ingufu nyazo, imikorere yayo ni 50 ~ 70% gusa. Secondary power power muri 30 w munsi yo gutakaza hafi 20 ~ 30%, 50 w munsi yo gutakaza hafi 15 ~ 20%, 100 w munsi yo gutakaza hafi 10 ~ 15%, 100 w hejuru yo gutakaza hafi 10% hepfo, hejuru igihombo ibipimo byerekeranye nuburyo busanzwe bwo gucomeka. Niba gahunda ya R-yihinduramatwara, c-ihinduranya na toroidal ihindura, ibipimo byigihombo bigabanuka.

Ukurikije imbaraga zose zibanze za transformateur ibarwa hejuru yibanze irashobora gutoranywa. Agace k'icyuma S = axb (cm2). Nkuko bigaragara ku gishushanyo. Guhindura imbaraga zigaragara nubusabane hagati ya s nuburyo bukurikira: s = K √ P1

P. Muri icyo gihe, urebye urupapuro rwicyuma cya silicon hagati y irangi ryerekana, ingaruka zicyuho, umubano K na P1 ni:

Agaciro P1 K.
10VA 2 ～ 2.2
50VA munsi ya 2 ~ 1.5

LOOVA munsi ya 1.5 ~ 1.4

2. Kubara impinduka kuri volt

Nyuma yo guhitamo intangiriro s. Noneho menya umubare wimpinduka kuri volt, kugirango uhindure transformateur ifite umuyaga ushimishije. Bikunze gukoreshwa muburyo bwa empirike: N = (40 ~ 55) / S, N numubare wimpinduka kuri volt.

Ukurikije ubuziranenge butandukanye bwicyuma cyo gutoranya icyuma cya silikoni 40 ~ 55. Ibyuma birebire cyane bya silikoni, hamwe nijisho ryo kureba hejuru yubunzani bwa kristu. Kandi kuvunika cyane, inshuro 1 kugeza kuri 2 gusa zimeneka, zimenetse ku buryo butaringaniye, coefficient ifatwa nka 40. Niba hejuru yicyuma cya silicon icyuma gisukuye, kunama inshuro 4 kugeza kuri 5 ntabwo byoroshye kumeneka, igice cyuburyo bwiza umurongo ugororotse, coefficient ifatwa nkibirenga 50.

Shakisha umubare wimpinduka kuri volt wikubye na 220V niyo mpinduka yambere, igwijwe numubare wa voltage ya kabiri isabwa aribwo buryo bwa kabiri bwo guhinduranya. Kuberako insinga ifite kwihanganira, gutembera kunyuze mumashanyarazi ya voltage, impinduka ya kabiri igomba kwiyongera kuri 5 ~ lO% (ukurikije imizigo ihitamo imitwaro, ikigezweho gishobora kwiyongera nigice kinini).

3. Guhitamo diameter

Ukurikije ubunini bwimitwaro ihindagurika, hitamo diameter zitandukanye zinsinga. Inzira ikurikira irashobora gukoreshwa kugirango umenye:
d = O.8√I.
Igice: l - A. d (diameter ya wire) - mm.

4. Uburyo bwo guhinduranya uburyo bwo kwirinda

Muri iki gihe rero, imbaraga zo gukumira insinga zometseho zateye imbere rwose. Kuriimbaraga ntoyahafi 50W, mubisanzwe tujya hamwe na skeleton ya plastike ya flame-retardant hanyuma tugashyiraho imirongo. Gusa menya neza gukoresha insinga zifite imbaraga nyinshi zometseho insinga, kandi mugihe urimo uzunguruka, komeza ibintu byose bitondekanye kumurongo - nta ntera nini ya diagonal yemerewe! Ibi bifasha kwirinda kongera itandukaniro rya voltage hagati yinsinga. Kuri transformateur zirenga 50W, kubera ko hari impinduka nke kuri volt, itandukaniro rya voltage hagati yinsinga riba hejuru. Nibyiza gushyira hasi impapuro zikingira (nka 0,05mm yububiko bwimpapuro cyangwa impapuro za kraft) kuri buri cyiciro nkuko ubihindura.

Urashaka rwose kubuza ibice byose byo hejuru kunyerera murwego rwo hasi! Kwikingira hagati yumuyaga bigomba guterwa nubunini wa voltage urimo. Hagati yinzego zibanze, gerageza byibuze ibice bine byimpapuro 0.1mm ya kabili-simbuka ukoresheje kaseti yifata hano! Niba transformateur yawe ntoya ifite amatsinda arenze abiri ya kabiri yiziritse hamwe, menya neza ko wongeramo ibice bibiri byimpapuro zikoreshwa hagati ya buri tsinda. Niba kandi iyi transformateur igiye mubikoresho byamajwi cyangwa amajwi? Ntiwibagirwe gushyiramo amashanyarazi ya electrostatike yo gukingira muri ibyo bice byinshi. Umaze gukora ibyo bintu byose bihindagurika, witondere mugihe winjizamo amabati ya silikoni - bigomba guhuza neza kugirango utabona urusaku rwa electromagnetiki rwangiza ibintu.

Yaba impapuro ebyiri za E cyangwa EI zifite impapuro, zigomba kuba zipakiye hamwe nta cyuho; kubambuka birashobora gufasha! Mugihe ushyizemo ibice bike byanyuma (hafi bine cyangwa bitanu), kora uhereye hagati kugirango utangiza imigozi yose yinsinga. Noneho reka tuyumishe hanyuma tuyibike irangi nyuma! Kuri transformateur munsi ya 50W, urashobora gukoresha uburyo bwo kumisha endothermic yumuti: umuzunguruko mugufi byose byambere byuzuza hanyuma hanyuma ugahuza itara (60 ~ 100W / 220V) mukurikirane hamwe nimbaraga nyamukuru kugirango yishushe mu buryo bwikora. Nini nini, hejuru ubushyuhe, ariko muburyo bufunze, kuburyo ubushyuhe buri munsi ya dogere 80 ni umutekano.
