Magawo a core a kutsogoleredwa pazithunzi zikuluzikulu amapangidwa ndi mikanda ya LED ndi madalaivala i ic. Chifukwa cha kumverera kwa madambo kupita ku magetsi okhazikika, magetsi oopsa kwambiri amatha kuyambitsa kuwonongeka kwa malo okhala owunikira. Chifukwa chake, miyeso yokhazikika iyenera kumwedwa pakukhazikitsa kwatsogozedwa kutsogoza zojambula zazikulu kuti mupewe magetsi akufa.

Magetsi ogwiritsira ntchito zojambula zikuluzikulu amakhala pafupifupi 5V, ndipo ntchito yayikulu yomwe ili pansipa 20A, machitidwe a ma LED amadziwitsani zoopsa komanso magetsi osagawanika. Izi zimafuna kuti tizindikire izi popanga ndikugwiritsa ntchito njira yokwanira, ndikuwonetsetsa zokwanira, ndikuchita njira zothandizira kuteteza chinsalu chachikulu. Ndipo kukhazikika kwamphamvu ndi njira yogwiritsidwa ntchito poteteza kutsogozedwa.
Kodi nchifukwa ninji magetsi amafunikira kukhala pansi? Izi zikugwirizana ndi njira yosinthira magetsi osintha. Maulamuliro athu akulu osinthika ndi chipangizo chomwe chimasinthira mphamvu a AC 50V DC Maper Mphamvu yokhazikika pa njira zingapo monga kusefukira kwa kukonzanso. Kuti muwonetsetse kutembenuka kwa ma ac / DC kwa magetsi, wopanga magetsi alumikizane ndi waya wa emi pansi pa kapangidwe ka ma AC220V National 3C. Kuonetsetsa kukhazikika kwa Ac220V, zopereka zonse zamphamvu zikhala ndi zotayira pakugwiritsa ntchito, ndikutha kwa madongosolo a 3.5Magetsi amodzi. Magetsi otayidwa ndi pafupifupi 110V.
Chithunzi cha LED sichitha, kutayikira komwe kumachitika sikungangoyambitsa kuwonongeka kwa chip kapena moto woyaka. Ngati magwero oposa 20 amagwiritsidwa ntchito, kutayikira komwe kumafika pamakono 70Ma kapena kupitirira. Ndikokwanira kuchititsa kuti muchepetse kuchita ndikudula magetsi. Ichi ndiye chifukwa chake zojambula zathu za Add sizingagwiritse ntchito zoteteza. Ngati chitetezo chatha sichilumikizidwa ndipo chophimba cha LED sichinakhazikitsidwe, omwe alipo kale pa magetsi amapitilira chitetezo cha thupi la munthu. Mphamvu ya 110V ndiyokwanira kuphedwa! Pambuyo kuwonongeka, magetsi a mphamvu zomwe zimapezeka pafupi ndi 0 kwa thupi la munthu. Zikuwonetsa kuti palibe kusiyana pakati pa magetsi ndi thupi la munthu, ndipo kutayikira komwe kumayendetsedwa pansi. Chifukwa chake, chophimba cha LED iyenera kukhala chilito.
02 Njira Yolondola ndi Maganizo Olakwika a Proving Slaven
Ogwiritsa ntchito nthawi zambiri amagwiritsa ntchito njira zolakwika mpaka pamakina oyendetsa ndege, kuphatikiza:
1. Amakhulupirira kuti kutha kotsika kwa mawonekedwe a kunja kuli kulumikizidwa pansi, kotero palibe chifukwa chokhazikitsa zenera lalikulu;
2. Amakhulupirira kuti magetsi amatsekeredwa pabokosi, ndipo mabokosi amalumikizidwa wina ndi mnzake kudzera m'magulu otsekerapo ndi zomangira, chifukwa chake pamakhala zingwe zoyimira magetsi.
Pali kusamvana mu njira ziwirizi. Ming'alu yathu imalumikizidwa ndi anchiro a nangula, omwe amaphatikizidwa ndi konkriti. Kukana kwa konkriti kuli mkati mwa 100-500 ω. Ngati kukana kwamphamvu kuli kwakukulu kwambiri, kumabweretsa kutaya kosasinthika kapena kotsalira. Bokosi lathu limathiridwa ndi utoto, ndipo utoto ndi wosauka wamagetsi, womwe udzapangitsa kuti kulumikizana ndi magetsi, ndipo kungayambitse kukana kwamanja, ndipo kungayambitse zingwe zamagetsi kuti zisokoneze chizindikiritso chachikulu cha LED. Popita nthawi, mawonekedwe a bokosi lalikulu la chiwonetsero cha LED Izi zidzapangitsa kuti kufooketse kapena kufooketsa kokwanira kwa zinthu zomwe zidapangidwa. Pangani zoopsa. Kupezeka kwa ngozi zachitetezo monga kutaya kwamakono, kugwedezeka kwamagetsi, kusokonezedwa ndi kuwonongeka kwa tchipisi.
Ndiye, chiyenera kukhala chiyani moyenera?
Mphamvu yamagetsi yamagetsi ili ndi ma terming atatu owonda, ndiye kuti ndi waya wamoyo, osalowerera waya, ndi phokoso. Njira yolondola ndikugwiritsa ntchito waya wokhazikika wa chisoti wophatikizidwa kuti mulumikizane ndi kutseka ma aya onse amphamvu mu mndandanda, kenako ndikuwatsogolera kuti alumikizane ndi mapidwe. Ngati kulibe malire pamalopo, imatha kulumikizidwa ndi mapaipi amphongo ngati chitsulo chachitsulo kapena zitsulo zonyansa zomwe zikugwirizana bwino ndi nthaka. Kuonetsetsa kuti mumalumikizana bwinobwino matupi achilengedwe omwe amayenera kuchitika, kenako waya wapansi uyenera kukhala wotsekeka kwambiri pamtunda wopanda kulumikizana. Komabe, mapaipi ophulika ndi ophulika ngati gasi sadzagwiritsidwa ntchito. Kapena kuyika ma elekitirodi oyambira pamalo. Thupi lamantha limatha kupangidwa ndi zitsulo zosalala kapena zitsulo zachitsulo, zopingasa molunjika kapena molunjika pansi ngati malo osavuta. Mfundo yofunika iyenera kusankhidwa m'malo akutali kuti muchepetse anthu kapena magalimoto kuti asawononge thupi. Tikakhala pansi, kukana kwa nthaka kuyenera kukhala kochepera 4 omms kuti muwonetsetse nthawi yayitali. Tiyenera kudziwa kuti chidengeni champhamvu chopumira chimafunikira nthawi yochepa yopanga pansi panthaka panthawi yomwe imatha kutentha kwa nthawi yochepa. Ngati chophimba cha LED chimakhazikitsidwa ndi chitetezero chotetezera, chomwe chitha kukhala chapamwamba kuposa cha chinsalu cha LED, ndipo mphezi yomwe ilipo imaperekedwa pazenera lino kupita pazenera. Chifukwa chake kutchinjiriza kwa zojambula zamagetsi sikungalumikizidwe ndi chitetezero chotetezera chotchinga, ndipo madicofu oteteza kuyenera kukhala osachepera 20 mita kutali ndi chitetezero chotetezera. Pewani mgwirizano womwe sungathe.
