Amene asankha kumanga nyumba amakumana ndi ntchito yovuta.Zimakhala zovuta kukhala ngati makontrakitala wamba kwa anthu ena, koma mukaganiza zomanga nyumba yanu, monga momwe makolo anga adachitira kumayambiriro kwa zaka za m'ma 1970, zimakhala zovuta kwambiri.Zisankho miliyoni imodzi ziyenera kupangidwa m'malo opanda chidziwitso komanso osinthika mwachangu, ndipo sitepe yolakwika ikhoza kukuyikani muvuto losatha.Kuphatikizidwa ndi bajeti yomwe anthu anga akuyenera kugwira ntchito molimbika, ndi chozizwitsa kuti akhoza kukhala opambana monga kale.
Komabe, izi zikadali pafupi m'malo angapo.Ndimakumbukirabe kuti bambo anga ankavutika ndi mawaya a m’nyumba.Waya wa aluminiyamu ndi wotsika mtengo kwambiri, pomwe mtengo wa waya wamkuwa wakwera kwambiri posachedwa.Anakukuta mano ndi kupempha katswiri wa zamagetsi kuti ayike mkuwawo, chomwe chinali chisankho chanzeru, chifukwa nyumba zomwe zidangomva kulira kwa mawaya otsika mtengo zitha kuwotchedwa kudutsa United States.
Chakumapeto kwa zaka za m'ma 1960 ndi kumayambiriro kwa zaka za m'ma 1970, zomwe zinachitika m'mafakitale opangira magetsi okhala ndi nyumba ndi malonda zinali zodula ndipo nthawi zina zinali phunziro lomvetsa chisoni pamapulojekiti olephera.Tiyeni tione mmene zimenezi zinachitikira.
Kuti mumvetse fiasco ya mawaya a aluminiyamu, munthu ayenera kukumbukira osati sayansi yakuthupi ndi zomangamanga zamagetsi, komanso mphamvu za msika zomwe zinapangitsa mawaya a aluminiyumu m'nyumba zogona kukhala zokongola kwambiri panthawiyo.Kumayambiriro kwa zaka za m’ma 1960, kupangidwa kwa mkuwa padziko lonse kunali kokulirapo, koma zoletsa kupanga modzifunira zochepetsera kuchulukitsitsa kwamitengo zidakwera.Pafupifupi nthawi yomweyo, kuchulukirachulukira kwa nkhondo ya Vietnam komanso kutukuka kwamakampani omanga nyumba kudakulitsa kufunikira kwa mkuwa, pomwe kukhazikitsidwa kwamakampani amkuwa ndi opanga kunja komanso kumenyedwa kwa ogwira ntchito m'migodi kuletsa kuperekedwa.Kufinyidwa pa malekezero onse a kaphatikizidwe ndi kufunikira kwa equation, mtengo wamkuwa pafupifupi kuwirikiza katatu pakati pa 1962 ndi 1964.
Waya wamkuwa wakhala nthawi yayitali yopangira ma wiring a nthambi zogona komanso zamalonda, ndipo mtunda wa waya kuchokera pamalo onyamula katundu kupita ku magetsi ndi zitsulo zozungulira nyumbayo wakhala wautali.Opanga magetsi amadziwa bwino zamkuwa ndipo adalemba malamulo amagetsi ozungulira mawonekedwe ake, ndipo opanga zida apanga masiwichi, soketi ndi zolumikizira makamaka mawaya amkuwa.Komabe, chifukwa cha mizu yakuya ya mkuwa, kukwera kwamitengo kunayamba kusintha mawaya amkuwa kukhala antimony, ndipo opanga magetsi adayamba kumva kulimba kwapansi.Zina ziyenera kulipidwa.
Lowetsani aluminiyamu.Aluminiyamu ndi kondakitala wabwino kwambiri wamagetsi-onyalanyaza zitsulo zamtengo wapatali, aluminiyamu amatsata mkuwa pa tchati cha conductivity.Aluminiyamu yakhala ikugwiritsidwa ntchito pa waya wamagetsi kwa nthawi yayitali, koma imagwiritsidwa ntchito makamaka ndi makampani othandizira pakuwongolera ma waya apamwamba pamakina ogawa magetsi.Kulemera kwa aluminiyamu ndi mtengo wotsika ndi phindu lalikulu.Aluminiyamu imagwiritsidwanso ntchito m'nyumba zokhalamo, makamaka pakuthirira kothirira kuchokera kumitengo yogwiritsira ntchito kupita ku mita yamagetsi kukayika malo.Komabe, ngakhale aluminiyumu imapezeka muzowumitsira zovala komanso mawaya apamwamba a nthambi, sagwiritsidwa ntchito m'mabwalo anthambi opepuka omwe amapanga mawaya ambiri anyumba.Zonse zidzasintha.
Pofuna kuthana ndi vuto la mkuwa, opanga waya anayamba kupanga mawaya a aluminiyamu a 15 A ndi 20 A mabwalo a nthambi.Derali nthawi zambiri limakhala ndi mawaya a 14 AWG ndi 12 AWG amkuwa, motsatana.Komabe, monga aluminiyamu, madutsidwe ake akadali pafupifupi 60% yamkuwa.Choncho, waya wa aluminiyumu wa dera la nthambi uyenera kukwezedwa mpaka kukula kwa AWG.Dera la 15 A ndi 12 AWG, ndipo dera la 20 A ndi 10 AWG.Opanga amayenera kugwiritsa ntchito zitsulo zambiri, koma aluminiyamu ndi yotsika mtengo kwambiri kotero kuti imakhala ndi nzeru zachuma.Chotsatira chake chinali chakuti mawaya a aluminiyamu anayamba kulowa m’dera la nthambi yogonamo, n’kufika m’nyumba 2 miliyoni pakati pa 1965 ndi 1972.
Chisankhochi chidzakhala chopanda phindu pazifukwa ziwiri.Yoyamba ndi aloyi ya aluminiyamu yosankhidwa ndi wopanga waya.Waya wothandizira amagwiritsa ntchito aloyi yotchedwa AA-1350.Ngakhale AA-1350 ndiyoyenera kugwiritsidwa ntchito pamakina ogawa magetsi apamwamba komanso apansi panthaka, ndiyofunika kwambiri aluminiyamu yoyera yokhala ndi zitsulo zotsatizana, ndipo mawonekedwe ake ndi osiyana kwambiri ndi mkuwa.Chifukwa cha kuchuluka kwake kwamafuta owonjezera, aluminiyamu ya AA-1350 imawonetsa kugwa kwakukulu, kupindika pomwe waya wachitsulo ukukula ndikulumikizana chifukwa cha kutentha.
Kuthamanga kwa kugwirizana kwa magetsi kungakhale koopsa.Pamene mayendedwe amakono akuyenda, kondakitala aliyense amawotcha, koma chifukwa cha kuchuluka kwake kowonjezera, aluminiyumu amakula kuposa mkuwa.Mawaya okulitsa ndi kuchepa amatha kumasula ma terminals, omwe amamasula mawaya ndikupangitsa kuti mawaya azizungulira, zomwe zingayambitse kutentha kwambiri komanso kukwapula, mpaka potsirizira pake gwero lamoto limapangidwa m'makoma a nyumbayo.
Kuyika kolakwika kumatha kukulitsanso kukwapula, zomwe zimachitika nthawi zambiri akatswiri amagetsi amasintha kuchokera mkuwa kupita ku aluminiyamu.Aluminiyamu ndi yofewa kwambiri kuposa mkuwa, chifukwa chake ndizovuta kupeza torque yoyenera ya screw terminal.Aluminiyamu imatulutsanso okosijeni mwachangu ikakumana ndi mpweya, ndikupanga wosanjikiza wocheperako womwe ukhoza kuwonjezera kukana kwa kulumikizana.Waya wa aluminiyamu uyenera kuthandizidwa ndi zotetezera musanathe, koma kawirikawiri.Kuphatikiza apo, opanga masiketi ndi ma switch amachedwetsa kusintha zinthu zawo kuti zigwirizane ndi kufunikira kwa aluminiyamu, zomwe zimapangitsa kuti maulumikizidwe osadalirika azikhala osavuta kukwawa.
Pomaliza, chemistry yoyambira ikuwoneka kuti yanyalanyazidwa.Kumbukirani kuti malinga ngati zitsulo zosiyana zimagwirana, mphamvu yamagetsi idzachitika.Chomwe chimafunika kuchititsa dzimbiri ndi kachulukidwe kakang'ono ka electrolyte, monga kukanda mpweya wamadzi mumpweya wotentha ndikulowa m'makoma ozizira akunja ndi mawaya.Malumikizidwe owonongeka ndi osagwirizana kwambiri ndi zotsatira zodziwikiratu.
Pamene nyumba ya aluminiyamu yawaya inayamba kuyaka, ozimitsa moto ndi osintha inshuwalansi sakanatha kuzindikira vutoli, ndipo masiku ogwiritsira ntchito waya wa AA-1350 anatha.Pofika m'chaka cha 1972, makampani opanga magetsi adasintha mwachindunji mawaya a aluminiyamu kuchokera kumagetsi osinthidwa, omwe adalongosola njira zatsopano zopangira mawaya a aluminiyamu, kenako adatembenukira kwa opanga zida, omwe adasintha malonda awo kuti azigwirizana ndi mawaya a aluminiyamu.Opanga mawaya adasinthanso zinthu zawo, ndikupanga ma alloys atsopano pamndandanda wa AA-8000, kusakaniza chitsulo mu osakaniza kuti achepetse zomwe zikuyenda.
Komabe, palibe chilichonse mwa izi chomwe chingasunge aluminiyumu mudera lanthambi.Pofika m’katikati mwa zaka za m’ma 1970, madera ambiri anthambi m’nyumba yatsopanoyi sankagwiritsanso ntchito aluminiyamu, koma anali asanawonongeke.Maziko oyika mawaya a aluminiyamu ndiakuluakulu, ndipo nyumba za nthawi imeneyo zinkayang'aniridwa mosamalitsa ndi oyang'anira nyumba akasintha eni ake.Chiwopsezo cha mawaya a aluminiyamu chatulutsa zinthu zosiyanasiyana kuti zichepetse chiwopsezo, kuyambira zolumikizira zokwera mtengo kwambiri kupita ku ma crimp apadera omwe mawaya ozizira amawotcherera a aluminiyamu kupita ku zingwe zamkuwa.Ndilinso mwayi wochotseratu waya wozungulira nthambi ya aluminiyamu ndikuyiyika mkuwa, ngakhale izi ndizokwera mtengo komanso zowononga.
Pamene mphamvu za msika zikutsutsana ndi machitidwe abwino a uinjiniya, zoyesayesa zamakampani pa aluminiyamu zidakhala phunziro lokwera mtengo.
Vuto apa sikuti mawaya ndi otsika mtengo.Kungoti anthu sadziwa kugwiritsa ntchito bwino.Mwachiwonekere, uku sikutsika kwa njira zina zopangira waya zamkuwa.
Pali vuto lina ndi waya wa AL.Kutentha ndi chinyezi zinapangitsa kuti iwonongeke.Ndataya waya wapansi waukulu ndikugwera ku zingwe ziwiri, ndipo zotsalazo zinali fumbi.Izi zipangitsa kuti mawaya otentha awoloke, ndikupangitsa kuti voteji idumphire ku 200V, zomwe zikuwonetsa kuti babu yanga yotsogola ikuchepera / kuwala.
Ndinayika gulu laling'ono la 100A kunyumba, ndipo katswiri wamagetsi yemwe ndinamufunsa anandiuza kuti ndigwiritse ntchito Al chifukwa imawononga pafupifupi 1/10.Mwa kuyankhula kwina, ngati atayikidwa molondola, palibe choopsa.Mulimonsemo, mawaya omwe amalowa m'nyumba kuchokera mumsewu onse ndi 95% Al, ndipo siinatenthe moto!Chinyengo ndi torque yoyenera, zolumikizira zovotera ndipo palibe mpweya.
Pambuyo pa zaka 6, ndidzayang'ana kugwirizana kwanga chaka chilichonse, ndipo ndayang'ana ESA popanda vuto lililonse.Ngati atachita bwino, palibe chowopsa.Vuto m'mbuyomu linali zosintha zamkuwa zolumikizidwa ndi mawaya a aluminiyamu, etc.
Inde, ngati ntchitoyo ndi yolondola, waya wa aluminiyamu ndi wotetezeka.Chimodzi mwazovuta ndi dera la nthambi ya Al ndikuti eni nyumba nthawi zambiri amasintha masiwichi ndi zitsulo popanda kudziwa ukadaulo wolondola, kapena kulumikiza zida zowunikira ku mtedza wa waya.
Monga mwini nyumba, ndikhoza kutsimikizira.Nyumba yanga ili ndi zotchingira zitsulo kupita ku bokosi lachitsulo.Pali zotsekera zakuda ndi zoyera mkati mwa MC, komanso ma conductor a aluminium owonekera.Ngati kuthetsedwa molondola, ili si vuto.MC ndiye kwenikweni.Musanalowetse aluminiyumu mu chowonjezera, aluminiyumu iyenera kudulidwa kapena kupindika kumbuyo kunja kwa MC.Komabe, m'mabokosi ochepa, eni nyumba am'mbuyomu adalumikiza zitsulo zotayidwa pansi pa socket, komanso mtedza wa waya wamkuwa m'bokosi lokhala ndi zitsulo zingapo.Khalidweli silimandidetsa nkhawa (Ndathetsa mavuto onse tsopano), koma limatsimikizira mfundo yakuti ndidzachita chilichonse ndikakumana ndi alendo.
Ndinachita izi moumiriza wa inspector.Izi sizowona, koma nthawi zambiri sizikhala vuto, chifukwa zikamagwira ntchito mosasamala, nthawi zambiri sizisuntha mokwanira kuti zikhudze chilichonse chosuntha.Ndimakonda kugwiritsa ntchito zitsulo ndi ndege yapansi (waya wobiriwira wotsekedwa ku US).Zida zimafunikabe kumamatira, koma zida za aluminiyamu, kugwiritsa ntchito mawaya apadera amkuwa nthawi zambiri kumapangitsa kuti nthaka ikhale yodalirika (inde, mawu awa akhoza kulungamitsidwa: zopinga zamkuwa nthawi zambiri zimasungidwa pamtengo woyikidwa, pomwe zida za aluminiyamu zokhala ndi zida. Chalk, Al classification ndi Chalk m'mabokosi aluminiyamu nthawi zambiri kuchuluka kwa nthawi, ngakhale popanda madzi amadzimadzi Zida zimayenera kukhala pansi pa malekezero onse awiri asanayambe kukhazikitsa makina atsopano kulephera kumadutsa malire?
Sikuyenda ndi kukhudza kanthu.Yatsala pang'ono kumasuka mu cholumikizira, oxidize ndikukhala cholumikizira champhamvu, chomwe chimatenthetsa ndipo pamapeto pake chimasungunula pachimake cha aluminiyamu.Aluminiyamu yokhala ndi okosijeni ndi aluminium oxide yokhala ndi kutentha kwambiri kosungunuka, koma aluminiyamu yosasunthika mkati imakhala ndi malo otsika kwambiri osungunuka.Izi zipangitsa kuti kulumikizana kwanu kugwe kuchokera mkati ndikupangitsa kuti kulumikizana kukhale komasuka.
Kwa kugwirizana kwa nthaka, ilibe panopa kwa nthawi yaitali (mwachiyembekezo), kotero kutentha sikulinso vuto.Kuti cholumikizira chapansi chikhale cholumikizidwa, kukana kwapansi kumangofunika kukhala kotsika kuposa kwanu ndikupereka kulumikizana kwabwino kokwanira kuti muyendetse pakali pano kuti muyendetse woyendetsa dera.
Chophimba chachitsulo si nthaka.aluminiyamu.Waya wapansi ndi waya pansi ndikupindika mmbuyo momwe mukufotokozera kuti mutsike zida za MC.The spiral aluminiyamu chubu adzakhala oxidized monga aluminiyamu ena, ndipo zikavuta kwambiri kungachititse kuti nthaka madzi kuyenda mu utali wonse wa ozungulira.Izi zitha kukhala zokwanira kuteteza wophwanya dera kuti asagwe, pomwe nthawi yomweyo akugwira ntchito ngati chinthu chotenthetsera, amatha kukwiriridwa m'malo otsekereza a moyo wosadziwika komanso kuyaka.aluminiyamu.Pali waya wapansi kuti apereke njira yotsika yotsutsa pansi kuti izi zisachitike.
Ngati kugwirizana kwanu kwa nthaka kuli ndi mavuto owonjezera kutentha, chinachake chiri cholakwika-pokhapokha ngati pali vuto, nthaka sidzawonapo panopa.Sindikudziwa zofunikira za NEC pa Al grounding.Zifukwa, koma ndikhala ndikusowa, ndikuganiza kuti ziyenera kulembedwa mwachindunji kwa Al.Njira ya UL.
Nthawi zina, zida zamawayilesi amagetsi zingafunikire kulemba mayeso a UL mu pepala loyera lomwe limakwaniritsa zofunikira zamawaya a NEC.Malo ambiri amakono ndi ma switch terminals ndi UL certified ndipo amatha kugwiritsidwa ntchito polumikizira waya wamkuwa.Waya wa aluminiyamu uyenera kupindika waya wamkuwa kuti ulumikizane ndi malo ogulitsira kapena malo okhalamo ndi switchgear.Pokhapokha ngati bungwe lovomerezeka la AHJ livomereza masinthidwe apadera, wopanga amati nthawi zambiri amakwaniritsa zofunikira zomwe zalembedwa ndi UL.R.

Ndidagwiritsa ntchito mitundu ingapo ya mawaya akumbuyo okhala ndi zomangira zokhazikika (lowetsani mawayawo kudzera pamabowo owongolera ndikumangitsa zomangira m'malo mokokera malekezero a waya)
Ndimakonda zowononga zatsopano, zomwe ndi mtundu wakale wa "push and hope" womwe ndidakumana nawo.
Ndasinthanso mulu wa soketi zokankhira zomwe zikutentha kwambiri.Sindisamala zomwe wina anena, sindimazigwiritsa ntchito.Izi sizili choncho pamene ma soketi apamwamba amawononga ndalama zoposa madola awiri.
Mtundu wokhala ndi fixing screw + clamp ukhoza kukhala wodalirika kuposa waya pansi pa screw type.Chokonzekeracho ndi kasupe wolimba wa copper alloy, kotero sichingayende ndi kutentha kwa njinga.Kuyambira zaka za m'ma 1960, uku kwakhala kusinthidwa kokhazikika kwa ma screw terminals.
Ndikukumbukira pamene adatuluka koyamba.Ndikukayika, koma ndimagwiritsabe ntchito backstab.Hei, ichi ndi chida cha UL.Mwamwayi, ndinakonzanso khitchini ya mnzanga yemwe anagula nyumba yomwe ndinamangapo mawaya zaka 20 zapitazo.Iyi ndiye nyumba yomwe ndidagwiritsa ntchito njira yakumbuyo.Ndikatulutsa socket kapena kusinthana kuti ndikonzenso madera ena, socket/switch imatha kugwa.Kukana kwakukulu, kuwonongeka koonekera kwa kutentha.Chomwe chidandidabwitsa ndichakuti zolumikizira zomwe zimagwiritsidwa ntchito masiku ano zidalowa m'malo mwa mtedza.
Chowumitsira zovala changa chimasiya kugwira ntchito pafupipafupi.Chifukwa chake, ndinayang'ana zolumikizira zonse mu chowumitsira.Palibe mwayi.Nthawi zina, nyumba yanga (yatsopano) inali ndi vuto ndi waya wowumitsira socket, kotero ndidatsegula.
Backstab?Zosakwanira.Wiring munthu amaganiza kuti ichi ndi backstab, ngakhale kwenikweni ndi backstab yomwe imafuna zomangira kuti zizimitsidwa.Nyumba yanga yatsopano inatenthedwa.

Kukweza kwina kwa magetsi kunapangidwa pazitsulo za kontrakitala wa nyumba ya tauniyo.Waya wandiweyani wa AL wandiweyani wa aluminiyamu wosakanizidwa siwoyenera kuyika pakhoma.Palibe mwayi wopindika.Mangani mkuwa ndi mfundo yolondola ndi anti-c bandi.Chimodzi mwazinthu zoyipa zomwe ndidachitapo.M'malingaliro, kusintha chidebe mu SoSF Ca kumafuna chilolezo ndikuwunika.Amagwiritsa ntchito owunika amakampani omwe sadziwa chilichonse pano, kuphatikiza magawo osavuta a madipatimenti kapena 1000/160."Oh ... ndipatseni mawindo anayi apadenga."Alibe kalikonse.Ndagwiritsa ntchito mpweya wabwino m'mphepete.Ndinawonanso chitoliro changa choyamba mu nthawi ya SF Victorian (pambuyo pa Clue).Wangwiro P-msampha mu mawonekedwe abwino.M'malo mwake.Roto Router yomwe ndinagwiritsa ntchito pano inati: “Uyenera kumeta tsitsi lako lalifupi.Apo ayi simungathe kuchita.Ndizovuta kwambiri.Ndinamulipira 300 mpaka 150. Komabe sindingathe kuzithetsa.Palibe kubweza.Ndimadana ndi zitsiru.Mukufuna chilichonse chopindulitsa.
Ndimagwira ntchito pakampani yamagetsi.Timagwiritsa ntchito zitsulo zovala zonse zamkuwa ndi zojambulazo za aluminiyamu zotchinga katatu (zojambulazo za aluminiyamu zoluka za aluminiyamu), pomwe kampani ya satana imagwiritsa ntchito ma kondakitala amkuwa omwe akugwira ntchito.Chifukwa cha zotsatira za khungu, timangofunika kuvala mkuwa.Sindinawone woyendetsa aluminium pakati, zingwe zambiri zopanda pake, koma palibe aluminiyamu.
Mukamagwiritsa ntchito AL, kuwonjezera mphamvu yamagetsi si njira yothetsera vuto la dzimbiri.Osatchulanso kuyanjana ndi zida zonse zomwe zikugwiritsidwa ntchito pano kapena zomwe zikuperekedwa.Kusintha kwanyengo padziko lonse lapansi kudzachititsa kuti anthu asamayende bwino ku gehena, pambuyo pake United States idzagwiritsa ntchito magetsi okwera kwambiri kuunikira mabwalo a zida zazing'ono zapakhomo.Chonde zimitsani POTUS yathu yapano isanakulolezeni kulipira zosinthazo.
Ndi kuyatsa kwa LED, sitifunikiranso mabwalo owunikira a 15A.Titha kugwiritsa ntchito mawonekedwe a 18v 120v 5A pakuwunikira ntchito.Dera limodzi limatha kuyatsabe nyumba yonse.
Timangofunika mapulagi a 15A kapena 20A kuti azigwiritsidwa ntchito potenthetsera zida, monga zotenthetsera mumlengalenga, toaster, ma ketulo, ndi zina zotero… komanso mafiriji, mafiriji, mafiriji ndi zoziziritsira mpweya.
Pokhapokha ngati mkuwa ukhale wokwera mtengo kwambiri, kusintha sikudzachitika.Kenako ndimatha kuwona njira zina, monga mphamvu zanzeru.Chipangizo cholumikizidwa chimalankhula ndi inverter, ndipo inverter imapereka mphamvu ndi voteji yofunikira mpaka 600v.Chifukwa chake, chowotcha chanu cha 1000W chidzafuna 600V motero amangodya 1.6A yapano, yomwe imatha kupitilira mzere wa 20 geji.Chotsani chowotcha ndi kuyika zala zanu, chikhoza kukhala 30V chokha.Malingana ngati zipangizo zikufunikira, magetsi amangowonjezeka.Dera lililonse liyenera kukhala loyendetsa kunyumba, zomwe zitha kuchotsera mtengo uliwonse wamawaya ang'onoang'ono.
Pepani!Ngati anthu ayamba kuchita masamu ngati awa, malo okhawo omwe titha kugwiritsa ntchito zida zamagetsi mnyumba yatsopano ndi kukhitchini!Kodi ndi zomwe mukufuna?!?Izo zikhoza kukhala imfa ya amateur.Anthu okhawo omwe amamanga chilichonse kwa mibadwomibadwo kuyambira pano ndi anthu omwe amagwira ntchito.
Sitidzawona 600V mnyumba.Zofunikira za insulation ndi mipata yogwirira ntchito zakhala zovuta kwambiri kuti zitheke kukhazikitsidwa mosamala komanso mwachuma.Monga momwe mudapangira, mabwalo anzeru adzakhalanso okwera mtengo kwambiri pamakina azipangizo.Dera lililonse liyenera kudyetsa chipangizo chimodzi ndendende.Ngati sizili choncho, chipangizocho chidzafunika kuyimira voteji wamba, ndiyeno dera lililonse lidzakhala locheperako ndi malire a voteji ya chipangizocho ndi voteji yofooka kwambiri, ndipo mphamvu yonyamula mawayayo iyenera kukhazikitsidwa. gwirani zida zonse zomwe zili pamagetsi otsika kwambiri ndi waya wamkulu wa geji.
Ngati dera lililonse lili ndi chosinthira cha AC cha makilowatt ambiri anzeru, timapindula chiyani pambali pa kuwonjezera mtengo wowonjezera?Kodi n'zotheka kusuntha uvuni kuchokera ku khoma kupita ku lina?Chowumitsa chanu chimachoka kuchipinda chochapira kupita kuchipinda chogona?Compressor yanu imachoka ku garaja kupita kuchipinda chosangalalira?Inde, zitsanzozi ndizopanda pake pamapangidwe, zokwanira kusonyeza kuti zambiri zosinthika zomwe zimapezedwa pamtengo waukulu ndizopanda ntchito kwa eni nyumba.Kupatulapo zochepa (monga zowumitsira tsitsi, ma ketulo amagetsi, uvuni wa microwave, toasters, turkey frying pan, zida zamagetsi), malo a sockets kwa ogwiritsa ntchito mphamvu zapamwamba amatha kuneneratu molondola pomanga kapena kumanganso, ndipo dera limapangidwa. kukhala otsikitsitsa Perekani mphamvu mosamala pa mtengo.Kuphatikiza pa kukwera mtengo kwa otembenuza anzeru a AC amphamvu kwambiri, ngati tinene kuti ogwiritsa ntchito olemera amawerengera 85% yamagetsi amagetsi ndipo mphamvu ya otembenuza anzeruwa ndi 97%, tidzawonjezeranso ndalama zamagetsi ndi 2.63%.Osati obiriwira kwambiri.
Ndikuwona kusintha kwanzeru m'tsogolo lathu.Low-voltage smart circuits adzakhala njira yachitetezo.Gulu la mababu a 1-n LED amatha kuyankhulana ndi kumtunda kwa smart circuit breaker-ngati wowononga dera sangathe kufotokozera ma mA omwe akudutsamo, akhoza kulengeza vuto, kuyambitsa kudziyesa kwa babu kuti adzilekanitse chipangizo cholakwika, ngati zimatsimikiziridwa kuti zida zonse zili Ngati zili zachilendo ndipo mawaya ndi olakwika, amatha kuyenda kapena kuyenda.Titha kuchitanso chimodzimodzi pazida zotsika magetsi komanso zotsika mphamvu monga ma charger amafoni, zoseweretsa, ndi zida zina zapakhoma.
Ndikufuna kuwona Smart Power Report* Panel GFCI ophwanya ma circuit okhala ndi mitengo yabwino.Nditha kugula socket ya 20A 120V GFCI pafupifupi US$15, pomwe 20A 120V GFCI panel breaker imawononga US$40.Mtundu wa bipolar 240V uli pafupi kuwirikiza kawiri.50A 240V gulu GFCI amakankhira mtengo wa 100 madola.Chitetezo chiyenera kukhala chotsika mtengo.Ndikufuna kuwona dera logwiritsa ntchito mphamvu mozungulira kuti ndipange zisankho zanzeru zogwiritsa ntchito mphamvu.
Kodi pali zowawa ku UK zofunitsitsa kuthandizira ma waya a aluminiyamu?Ndasuntha zida zambiri kumalo osungirako mafakitale a 3-phase ku UK, ndipo sindinagwirepo mawaya a aluminiyamu.Kodi simunawonepo kalikonse pano panyumba?
Womanga nyumbayo adagwiritsanso ntchito mapaipi apulasitiki kuti alumikizane ndi njira yoperekera madzi akunja kwa anthu kunyumba, zomwe zidalephera kumayambiriro kwa zaka za m'ma 1990 (onani pulani yayikulu), ndipo mapaipi a polybutene mkati mwa nyumbayo adagwiritsidwanso ntchito kugawa.Kulephera kupirira nyundo yamadzi, izi zinawononganso khoma lamkati chifukwa cha kuphulika kwa chitoliro.
Phunziro: Muyenera kulipira chilichonse chomwe msika ungakhale nacho, osati mtengo wotengera mtundu wa nyumbayo.Ngati womangayo atha kupanga zosankha zomwe zimasunga ndalama, phindu lake lidzawonjezeka.Simukusunga mtengo.Choncho, malamulo okhwima omangira ndi kuyendera amafunika.
Zaka makumi angapo pambuyo pake, clarinet kuchokera ku mita kupita kunyumba ikadali yolimba.PEX idapulumuka bwino m'nyengo yozizira posachedwa.
Ndimakonda chitoliro changa chamadzi ozizira chamkuwa, chitha kugwiritsidwa ntchito ngati cholumikizira pansi.Sindinalepherepo ndi mapaipi amkuwa… ndi mapaipi otsekera thukuta…chidutswa cha keke!
