Momwe mungatetezere magetsi a LED ku mphezi

Kugunda kwa mphezi ndi chinthu chofala kwambiri m'chilengedwe, makamaka nthawi yamvula. Kuwonongeka ndi kutayika komwe kumabweretsa kukuyerekezeredwa kukhala madola mabiliyoni ambiri chifukwa chaMagetsi a LED mumsewuchaka chilichonse padziko lonse lapansi. Kugunda kwa mphezi kumagawidwa m'magulu awiri: mwachindunji ndi mwachindunji. Mphezi yosalunjika makamaka imaphatikizapo mphezi yoyendetsedwa ndi yoyambitsidwa. Chifukwa mphezi yolunjika imapereka mphamvu yayikulu komanso mphamvu yowononga, magetsi wamba sangapirire. Nkhaniyi ikambirana za mphezi yosalunjika, yomwe imaphatikizapo mphezi yoyendetsedwa ndi yoyambitsidwa.

Kukwera kwa mphamvu komwe kumachitika chifukwa cha kugunda kwa mphezi ndi mafunde osakhalitsa, kusokoneza kwa mphamvu kosakhalitsa, ndipo kungakhale magetsi othamanga kapena magetsi othamanga. Amatumizidwa ku chingwe chamagetsi m'njira zina (mphezi yoyendetsedwa) kapena kudzera m'magawo amagetsi (mphezi yoyendetsedwa). Mafunde ake amadziwika ndi kukwera mofulumira komwe kumatsatiridwa ndi kugwa pang'onopang'ono. Chochitikachi chikhoza kukhala ndi zotsatira zoyipa kwambiri pamagetsi, chifukwa kuthamanga kwa mphamvu kosakhalitsa kumaposa mphamvu zamagetsi zamagetsi wamba, kuziwononga mwachindunji.

Kufunika Koteteza Mphezi pa Magetsi a Msewu a LED

Pa magetsi a m'misewu a LED, mphezi imayambitsa kukwera kwa magetsi m'mizere yamagetsi. Mphamvu ya kukwera kwa magetsi iyi imapanga mafunde mwadzidzidzi pamizere yamagetsi, yotchedwa mafunde a kukwera kwa magetsi. Kukwera kwa magetsi kumafalikira kudzera mu njira iyi yopangira mphamvu. Mafunde akunja a kukwera kwa magetsi amapanga kukwera kwa mafunde a sine a mzere wotumizira wa 220V. Kukwera kumeneku kumalowa mu nyali ya mumsewu ndikuwononga dera la magetsi a mumsewu a LED.

Pamagetsi anzeru, ngakhale kugwedezeka kwadzidzidzi kwa mphamvu sikuwononga zigawo zake, kungasokoneze magwiridwe antchito abwinobwino, zomwe zingachititse malangizo olakwika ndikuletsa magetsi kuti asagwire ntchito momwe amayembekezera.

Pakadali pano, chifukwa chakuti zida zowunikira za LED zili ndi zofunikira komanso zoletsa pa kukula kwa magetsi onse, kupanga magetsi omwe amakwaniritsa zofunikira zoteteza mphezi mkati mwa malo ochepa sikophweka. Kawirikawiri, muyezo wa GB/T17626.5 womwe ulipo umalimbikitsa kuti zinthu zikwaniritse miyezo ya 2kV differential mode ndi 4kV common mode. M'malo mwake, izi sizikugwirizana ndi zofunikira zenizeni, makamaka pakugwiritsa ntchito m'malo apadera monga madoko ndi malo ofikira, mafakitale okhala ndi zida zazikulu zamagetsi pafupi, kapena madera omwe mphezi zimagunda. Pofuna kuthetsa mkanganowu, makampani ambiri amagetsi am'misewu nthawi zambiri amawonjezera choletsa kugwedezeka kwa magetsi chokha. Mwa kuwonjezera chipangizo chodziyimira pawokha choteteza mphezi pakati pa cholowera ndi choyendetsa cha LED chakunja, chiopsezo cha mphezi kwa dalaivala wa LED wakunja chimachepetsedwa, zomwe zimawonetsetsa kuti magetsi akudalirika.

Kuphatikiza apo, pali zinthu zingapo zofunika kuziganizira pokhazikitsa ndi kugwiritsa ntchito dalaivala moyenera. Mwachitsanzo, magetsi ayenera kukhazikika bwino kuti atsimikizire njira yokhazikika kuti mphamvu ya mafunde itha. Zingwe zamagetsi zapadera ziyenera kugwiritsidwa ntchito pa dalaivala wakunja, kupewa zida zazikulu zamagetsi zomwe zili pafupi kuti zipewe mafunde panthawi yoyambira. Katundu wonse wa nyali (kapena magetsi) pa mzere uliwonse wa nthambi uyenera kuyendetsedwa bwino kuti apewe mafunde omwe amayambitsidwa ndi katundu wochuluka panthawi yoyambira. Maswichi ayenera kukonzedwa moyenera, kuonetsetsa kuti swichi iliyonse yatsegulidwa kapena kutsekedwa pang'onopang'ono. Njira izi zitha kuletsa mafunde ogwirira ntchito, kuonetsetsa kuti dalaivala wa LED akugwira ntchito modalirika.

TIANXIANG yawona kusintha kwaKuwala kwa msewu wa LEDKampaniyo yakhala ndi luso lalikulu pothana ndi zosowa zosiyanasiyana. Kampaniyo ili ndi malo otetezera mphezi ndipo yapambana satifiketi yoyesera mphezi. Imatha kupirira kukhudzidwa ndi nyengo yamphamvu ya mphezi pamagetsi, kuteteza kuwonongeka kwa zida ndikuwonetsetsa kuti kuwala kwa mumsewu kukugwira ntchito bwino ngakhale m'malo omwe mvula imagwa nthawi zambiri. Imatha kupirira mayeso a malo ovuta akunja kwa nthawi yayitali. Kuchuluka kwa kuwonongeka kwa kuwala ndi kochepa kwambiri kuposa avareji ya makampani, ndipo nthawi yogwirira ntchito ndi yayitali.
