Mawonekedwe a 7815

• 7815 volture a Remisator: Wodalirika komanso wosinthasintha

A 7815 Mphamvu ya magetsi imapereka zotulutsa zokhazikika za 15V, ndikupanga kukhala koyenera kuwongolera mabungwe omwe amafunikira chokhazikika komanso magetsi ovomerezeka.Zithunzi zake zimalimbikitsa kudalirika, chitetezo, ndi kusinthasintha kugwiritsa ntchito zosiyanasiyana.

• Magetsi osasinthasintha kwa mabwalo a chidwi

7815 Imatsimikizira kutulutsa kwa 152, koyenera kwa madera ogwiritsira ntchito magetsi kusintha kwa magetsi.Izi zimapangitsa kukhala koyenera kugwiritsa ntchito zida zolondola monga zida, masensa, ndi njira zopangira microcanter.

• Kusintha kwamphamvu kwa magetsi

Ndi magetsi ophatikizika a 17V mpaka 35V, wolembetsa amagwirizana ndi mabungwe osiyanasiyana olamulira monga mabatire, mabodza, kapena mapanelo a dzuwa.Kusintha kumeneku kumapangitsa kuti azigwiritsa ntchito mapulogalamu osiyanasiyana.

• Amathandizira pakufunikira kwamphamvu

Kupereka mpaka 1.5a wa zotulukapo, 7815 ndiyabwino pazida zazing'ono, oyendetsa madalaivala, komanso makina ophatikizika.Kutalika kwake kumakwaniritsa zofuna za zida zambiri zolimbitsa mphamvu.

• Omangidwa mogwirizana ndi kudalirika

Wothandizirayo amaphatikizanso mafuta ochulukirapo komanso zazifupi zazifupi zomwe zimalepheretsa kupewa kutentha komanso kuteteza onse ogulitsa komanso olumikizidwa.Izi zachitetezo izi zimatsimikizira ntchito yodalirika pakapita nthawi.

• Kuleza Kwabwino Kwambiri

Ndi kutentha kwakukulu koyambira kwa 125 ° C, 7815 amachita bwino kwambiri malinga ndi kusinthasintha kapena kutentha kwambiri.Izi zimapangitsa kuti zizikhala m'malo okhazikika mafakitale ndi kunja.

• Zosankha zingapo za phukusi la kapangidwe kake

Imapezeka mu-220, mpaka 3, ndi phukusi la KT, zomwe zimapereka 7815 zimapereka kuti zigwirizane ndi madera osiyanasiyana.Mapaketi ogwiritsira ntchito malo, pomwe zazikulu zimapereka kukonzanso kwabwino, kupereka kusinthasintha kwa milandu yosiyanasiyana.

Wothandizira wa 7815 ndi njira yodalirika komanso yosinthika yopezera mphamvu yokhazikika mu magetsi osiyanasiyana.Kuphatikiza kwake kwa ntchito yokhazikika, zinthu zachitetezo, komanso zosankha zimapangitsa kuti zikhale zosankha zambiri.

7815 Kuti Mukwaniritse Ulamuliro + 15V

Mukamalimbikitsa dera la A + 15V Kugwiritsa ntchito mphamvu ya voliyumu ya 7815 yamagetsi, njira mwatsatanetsatane yosankhidwa ndi kukonzanso komwe kumachitika.Kukhazikika kwa ma capactor a ceramic kumathandiza mwachindunji, katswiri wa 033uf mu kulowetsa ndi cartoctor ya 0.1uf pazomwe zidatulutsa.Makina ophatikizika ndi ofunika kuyang'anira mavuto okhazikika, kulimbikitsa zachilengedwe.Kuwayika pafupi ndi ma terminal a regilator kumachepetsa zinthu zomwe zingapangitse kusokoneza.Izi zamaliro zamaliro zomwe zimawoneka molondola, pomwe kusintha kochepa kumatha kukulitsa dongosolo lodalirika.

Kugwiritsa ntchito kwa carrace kwa carractors kuti awonongeke chifukwa cha ma electolytic.Chinthu chowoneka bwino ndikuyankha kwawo mwachangu - chinthu choyambirira cha kupendekera kwa phokoso ndi kukhazikika kwa dongosolo, makamaka kugwiritsa ntchito pafupipafupi.ESR yawo yotsika komanso njira yochepetsera imathandizira kuti ikhale ikuluikulu yochepa, ndikuwapangitsa kuti azisankha zomwe amakonda.Makhalidwe amenewa amathandizirana ndi madera oderana ndi odalirika, kusiyanitsa mwatsatanetsatane malo amphamvu aukadaulo.

Zochitika zamanja zimavumbula kuti luso la dera la 7815 la Regilait limapitilira zinthu zake zoyambirira, zopangidwa ndi zovuta zakunja monga kutentha ndi kusintha.Kukhazikika kwa magetsi kwambiri posinthana ndi katundu waposachedwa ndi vuto lodziwika, nthawi zambiri limathetsedwa ndikuwonetsetsa kuti asungunuke.Kugwiritsa ntchito kutentha kapena kukulitsa Airfulow kungakhale kopindulitsa pakukhazikika kwa dera.Kuyeserera kwakukulu ndi kusinthasintha kuwonetsa kuti kusindikizidwa kocheperako kumawonjezera magwiridwe antchito, kutsindika kufunika kosanthula kothandiza m'mayendedwe apadziko lonse lapansi.

Kugwiritsa ntchito LM7815

Wolamulira wa voliyumu wa LM7815 amalimbitsa mphamvu kwambiri pa mitundu yambiri yogwiritsa ntchito, kuonetsetsa zotulukapo zokhazikika + 15V.Khalidwe ili limathandizira mbali yake pothandizira microcorler komanso njira zingapo za sensor, pomwe malamulo a magetsi amafunikira kuti azigwiritsa ntchito bwino komanso kupewa kulephera.Kusintha kwake kumaonekera ngati othandizira osinthika osinthika, omwe amagwirizana ndi zosowa zakunja monga zophatikizira monga zotsutsana ndi zolimbitsa thupi, zomwe zimapangitsa kuti zisungunuke komanso kuzimitsa.

Kuthandizira kwamphamvu kwa microcorser komanso masensa

Kwa ntchito za Microcontroller, ma LM7815 osakhazikika osakhazikika, othandiza pamapulogalamu ambiri bwino ndikuchepetsa zolakwika, motero kudaliridwa kwa dongosolo.M'mapulogalamu a sensor, makamaka omwe amafunsidwa kwambiri ndi magetsi kwambiri, amapulumutsa mphamvu yosalekeza yofunikira kuti awerenge.Kumvetsetsa kumavumbula kuti kukhazikitsa magetsi okhazikika kumalepheretsa zolondola ndi kukhazikika kwa chipangizo chokhalitsa.

Malamulo Osinthika

Kulephera kwa LM7815 Monga wowongolera wosinthika amafafanizidwa kudzera pakuphatikizidwa kwa zinthu zakunja.Mwa kukana kapena kukhazikitsa chofunda, pali mwayi wosinthana kuti ukwaniritse zida zapadera, zomwe zimapereka kusinthasintha.Njirayi imathandizira kuti makonda owononga mtengo mu bolodi ya madera oyenda, potchula zofuna zosiyanasiyana zamagetsi zamagetsi popanda kufunikira kwa zinthu zatsopano.

Kugwira ntchito ngati chida chamakono

Pochita ngati malire apano, LM7815 amateteza zida mwa kuwongolera maulendo apamwamba kwambiri, potero muchepetse chiopsezo cha kuwonongeka kwa chinthu.M'mikhalidwe yomwe ikusintha milingo yamakono ikusokoneza zida zolumikizidwa, makamaka muukadaulo wotchinga, gawo ili limafunikira.Kuphatikiza pa LM7815 mkati mwa mphamvu yamagetsi kumapangitsa kutetezedwa ndi kuchuluka kwa nthawi, potero ndikugwiritsa ntchito kulimba kwa chida.

Kutumiza Malamulo pawiri

M'malo omwe amafunikira njanji zabwino komanso zoyipa, LM7815 imapereka yankho lodalirika.Poteteza chitetezero chobwezeretsa, chimatsimikizira umphumphu koyenera popereka magetsi otetezeka komanso oyenerera.Izi ndizopindulitsa kwambiri mu makonda omwe amakakamiza magawo enieni ogwiritsira ntchito ntchito moyenera, monga madiresi omvera, ndikusunga kudalirika kwakukulu.
