Kodi waya wa bulauni ndi wabwino kapena woipa?

Mawaya anthambi ogawa magetsi a AC ndi DC amalembedwa mitundu kuti azitha kuzindikira mawaya osiyanasiyana. Mu 2006, zizindikiro za mtundu wa ma wiring ku UK zidagwirizanitsidwa ndi zizindikiro zamtundu wa mawaya m'mayiko ena onse a ku Ulaya kuti zigwirizane ndi IEC 60446 yapadziko lonse lapansi. pansi. , ndipo waya wabulauni womwe takambirana m'nkhaniyi tsopano ndi waya wamoyo. Tsopano mwina mukufunsa, kodi waya wa bulauni ndi wabwino kapena woipa?

Pitirizani kuwerenga kuti mumvetse bwino kagwiritsidwe ntchito ka waya wa bulauni (wokhala).

Brown waya: zabwino zoipa?

Mu International Electrotechnical Commission (IEC) DC magetsi ozungulira mawaya amtundu wamitundu, waya wabulauni, womwe umatchedwanso waya wamoyo, ndi waya wabwino, wotchedwa "L+". Ntchito ya waya wa bulauni ndikutumiza magetsi ku chipangizocho. Ngati waya wa bulauni uli wamoyo ndipo sunalumikizidwe pansi kapena chingwe chosalowerera, pali mwayi woti mutha kugwidwa ndi magetsi. Chifukwa chake, musanayambe waya aliyense, onetsetsani kuti palibe gwero lamagetsi lolumikizidwa ndi waya wamoyo.

Kumvetsetsa Ma Wiring Color Codes

Chifukwa cha kusintha kwa ma code amtundu wa mawaya, ma network okhazikika ndi zingwe zamagetsi, komanso zingwe zilizonse zosinthika, tsopano zili ndi mawaya amtundu womwewo. Ku UK pali kusiyana pakati pa mitundu yawo yakale ndi yatsopano yamawaya.

Mawaya amtundu wa buluu amalowa m'malo mwa waya wam'mbuyo wakuda. Komanso, mawaya akale ofiira ofiira tsopano ndi ofiirira. Zingwe ziyenera kulembedwa bwino ndi ma code amtundu wawaya ngati pali kusakaniza kulikonse kwamitundu yakale ndi yatsopano kuti muteteze gawo lolakwika ndi kulumikizana kosalowererapo. Waya wa buluu (wosalowerera ndale) umachotsa mphamvu yamagetsi kuchoka pa choyikapo, ndipo waya wa bulauni (wokhala) umapereka mphamvu yamagetsi pachokhacho. Kuphatikizana kwa mawaya kumadziwika kuti dera.

Waya wobiriwira/wachikasu (pansi) umagwira ntchito yofunika kwambiri yotetezera. Kutumiza kwamagetsi kwa katundu aliyense kumatsatira njira yopita pansi yomwe ikuwonetsa kukana pang'ono. Tsopano, popeza magetsi amatha kudutsa m'thupi la munthu pamsewu wapansi pamene zingwe zamoyo kapena zopanda ndale zawonongeka, izi zikhoza kuonjezera chiopsezo cha kugwedezeka kwa magetsi. Pachifukwa ichi, chingwe chobiriwira / chachikasu chapansi chimayendetsa bwino chipangizocho, kuti izi zisachitike.

Chidziwitso: Mawaya okhazikika ndi zingwe zamitundu yosiyanasiyana, komanso zoyikapo ndi mabwalo, ziyenera kulembedwa ndi zizindikiro zochenjeza. Chenjezoli liyenera kulembedwa pa bolodi la fuse, chodulira dera, gulu logawa kapena gawo la ogula.

IEC DC Power Circuit Wiring Color Codes 

Kujambula kwamitundu kumagwiritsidwa ntchito mumagetsi a DC omwe amatsatira miyezo ya AC, monga mphamvu yadzuwa ndi malo opangira data pakompyuta.

Zopempha zitsanzo

Ngati mwagula choyatsira chowunikira posachedwa ndipo mukuyesera kuyiyika ku US, monga nyali yapayimidwe ya LED kapena kuyatsa kosungira katundu. Luminaire imagwiritsa ntchito miyezo ya waya padziko lonse lapansi, ndipo ndi njira iyi, kulumikizana ndikosavuta:

• Waya wabulauni wakuchokela kwanu ku waya wakuda wa nyumba yanu.
• Waya wabuluu wakuchokela kwanu ku waya woyera wa nyumba yanu.
• Wobiriwira wokhala ndi mzere wachikasu wa choyikapo nyali chanu ku waya wobiriwira wa nyumba yanu.

Mudzakhala ndi mawaya angapo omwe amalumikizidwa ndi zingwe zofiirira ndi zabuluu za unit yanu ngati mukuyenda pa 220 volts kapena kupitilira apo. Komabe, ma voltages okwera ayenera kugwiritsidwa ntchito pazovuta kwambiri. Magetsi ambiri amakono a LED amangofuna 110V, yomwe ndi yochuluka. Chifukwa chokha chovomerezeka cha izi ndi kukhalapo kwa mizere yayitali, monga kuthamanga mamita 200 kapena kuposerapo kwa mawaya ounikira mabwalo amasewera, kapena pamene malowa alumikizidwa kale ndi 480 volts.

Onani zina mwazolemba zathu pansipa.

• waya woyera zabwino kapena zoipa
• Momwe mungapangire mawaya amagetsi mchipinda chapansi chosamalizidwa
• Kodi kukula kwa waya kwa nyali ndi chiyani?
