Avo vanosarudza kuvaka imba vanotarisana nebasa rakaoma.Zvakaoma kuita se general kondirakiti kune vamwe vanhu, asi kana wafunga kuvaka imba yako, sezvakaita vabereki vangu mukutanga 1970s, zvinotonyanya kuoma.Sarudzo miriyoni dzinofanirwa kuitwa munzvimbo isina ruzivo uye inokurumidza kuchinja, uye nhanho isiriyo inogona kukuisa iwe munyonganiso isingaperi.Kubatanidzwa nebhajeti iro vanhu vangu vanofanira kushanda nesimba pariri, chishamiso chekuti vanogona kubudirira sepakutanga.
Zvisinei, izvi zvichiri pedyo munzvimbo dzakawanda.Ndichiri kuyeuka kuti baba vangu vainetseka newaya dzemba.Aluminium waya yakachipa zvakanyanya, ukuwo mutengo wewaya yemhangura wakakwira zvakanyanya nguva pfupi yadarika.Akageda-geda mazino ake ndokukumbira nyanzvi yemagetsi kuti iise mhangura, iyo yakanga iri sarudzo yakachenjera pakupedzisira, nokuti dzimba dzakanga dzakundwa nemasairini ewaya dzakachipa dzaizokurumidza kutsva muUnited States yose.
Mukupera kwema1960 nekutanga kwema1970, zvakaitika muindasitiri yemagetsi ekugara nekutengesa zvaidhura uye mune dzimwe nguva chaive chidzidzo chinosiririsa mumapurojekiti akakundikana.Ngationei kuti izvi zvakaitika sei.
Kuti unzwisise fiasco yealuminium wiring, munhu haafanire kuyeuka kwete chete zvinhu zvesainzi uye nyaya dzeinjiniya yemagetsi, asiwo masimba emusika akaita aluminium wiring muzvivakwa zvekugara zvinoyevedza panguva iyoyo.Pakasvika ma1960 apakuvamba, kugadzirwa kwemhangura munyika yose kwakanga kwakakwirira, asi ganhuriro dzokuzvidira dzokugadzira kuderedza kuwandisa kwakawedzera mitengo.Panenge panguva imwe chete, kuwedzera kweHondo yeVietnam uye kubudirira kweindasitiri yekuvaka dzimba kwakawedzera kudiwa kwemhangura, ukuwo kugadzirwa kweindasitiri yemhangura nevagadziri vekunze uye kurohwa kwevacheri kwakarambidza kupa.Yakadzvanywa pamativi ese ekugovera uye kudiwa equation, mutengo wemhangura wakapetwa katatu pakati pa1962 na1964.
Taya yemhangura yakagara iri chiyero chekugara uye chekutengesa bazi redunhu wiring, uye kureba kwewaya kubva panzvimbo yekuremerwa kusvika kune mwenje uye zvigadziko zvakatenderedza chimiro chave chakareba.Vagadziri vemagetsi vanoziva mhangura zvakanyanya uye vakanyora mitemo yemagetsi yakatenderedza maitiro ayo, uye vagadziri vemidziyo vakagadzira ma switch, sockets uye zvinobatanidza zvakananga waya dzemhangura.Nekudaro, nekuda kwemidzi yakadzika yemhangura, kuwedzera kwemitengo kwakatanga kushandura waya dzemhangura kuita antimony, uye makondirakiti emagetsi akatanga kunzwa kusimba kwepasi.Vamwe vanofanira kubhadharwa.
Pinda aluminium.Aluminium yakanakisa conductor yemagetsi-inoregeredza simbi dzakakosha, aluminium renji mushure memhangura pane conductivity chati.Aluminium yave ichishandiswa pakugadzira tambo dzemagetsi kwenguva yakareba, asi inonyanya kushandiswa nemakambani ekushandisa kune pamusoro pepamusoro wiring mumagetsi ekugovera masisitimu.Aluminium huremu huremu uye mutengo wakaderera mabhenefiti makuru.Aluminium yakashandiswa zvakare muzvivakwa zvekugara, kunyanya yekudiridza yedrip kubva pamapango emagetsi kuenda kumamita emagetsi kurodha nzvimbo.Nekudaro, nepo aruminiyamu ichijairika mune zvipfeko zvekuomesera uye yakakwirira amperage bazi redunhu wiring, haishandiswe mumaseketi ebazi akareruka anoumba kuwanda kweimba wiring.Zvose zvichashanduka.
Mukupindura dambudziko remhangura, vagadziri vewaya vakatanga kugadzira waya dzealuminium 15 A uye 20 A matunhu ebazi.Dunhu iri rinowanzo batwa newaya gumi nemana AWG uye gumi nemaviri AWG waya dzemhangura, zvichiteerana.Zvisinei, yakanaka sealuminium, conductivity yayo ichiri chete inenge 60% yemhangura.Naizvozvo, waya yealuminium yedunhu rebazi inoda kukwidziridzwa kune inotevera AWG saizi.Iyo 15 A yedunhu i12 AWG, uye iyo 20 A dunhu igumi AWG.Vagadziri vanofanirwa kushandisa simbi yakawanda, asi aruminiyamu yakachipa zvakanyanya zvekuti inoita kuti hupfumi huve nepfungwa.Somugumisiro, waya dzearuminiyamu dzakatanga kupinda mudunhu rebazi rekugara, richisvika mamiriyoni maviri edzimba pakati pa1965 na1972.
Ichi chisarudzo chichava chinopesana nezvikonzero zviviri.Yokutanga ndiyo aluminium alloy yakasarudzwa nemugadziri wewaya.Waya yekushandisa inoshandisa alloy inonzi AA-1350.Kunyangwe zvazvo AA-1350 yakanyatsokodzera kushandiswa pamusoro uye pasi pevhu simba rekugovera masisitimu, yakakosha aruminiyamu yakachena ine mamwe masimbi akawedzerwa, uye maitiro ayo emuviri akasiyana zvakanyanya nemhangura.Nekuda kwekukwira kwayo kwekuwedzera kwemafuta ekuwedzera, AA-1350 aruminiyamu inoratidza kunyura kwakakosha, kukanganisa kana waya yesimbi yawedzera uye zvibvumirano nekuda kwekudziya.
Iyo inokambaira yekubatanidza magetsi inogona kuve yakaoma.Sezvo huwandu hwazvino huchiyerera, chero conductor inopisa, asi nekuda kweiyo yakakwirira yekuwedzera coefficient, aruminiyamu inowedzera kupfuura mhangura.Kuwedzera uye kuderera kwewaya kunogona kusunungura zviteshi, izvo zvinosunungura waya uye zvinokonzeresa arcing, izvo zvinogona kutungamirira kune kupisa kwakawanda uye kuwedzera kukambaira, kusvikira pakupedzisira moto unogadzirwa mumadziro eimba.
Kuisa kusina kunaka kunogonawo kuwedzera kukwira, izvo zvinowanzoitika sezvo magetsi anochinja kubva kumhangura kuenda kualuminium.Aluminium yakapfava kupfuura mhangura, saka zvakaoma kuwana yakakodzera screw terminal torque.Aluminium zvakare inokurumidza oxidize kana yaiswa kumhepo, ichigadzira yakatetepa insulating layer iyo inogona kuwedzera kuramba kwekubatana.Aluminium waya inofanira kurapwa nekuchengetedza kusati kwapera, asi kashoma.Uyezve, vagadziri vezvigadziko uye maswichi vanga vachinonoka kugadzirisa zvigadzirwa zvavo kuti zvisangane nezvinodiwa zvealuminium, zvichikonzera kubatana kusingavimbike kunowedzera kukambaira.
Pakupedzisira, kemisitiri yekutanga inoratidzika kunge isina kufuratirwa.Rangarira kuti chero masimbi akasiyana achibata mumwe nemumwe, mhedzisiro yemagetsi ichaitika.Chinodiwa kuita ngura ishoma ye electrolyte, sekuita condensing mhute yemvura mumhepo inopisa uye kupinda mumadziro ekunze anotonhora uye waya.Corroded connections i-high-resistance connections nemigumisiro inofanotaurwa.
Sezvo imba yewaya yealuminium yakatanga kutsva, vadzimi vemoto uye vagadziri veinishuwarenzi havana kugona kuita kunze kwekuona dambudziko, uye mazuva ekushandisa AA-1350 imba wiring yakapera.Pakazosvika 1972, indasitiri yemagetsi yakange yagadzirisa zvakananga aluminium wiring kubva kune yakadzokororwa magadzirirwo emagetsi, ayo airatidza mafomula matsva ealuminum wiring dimensions, ndokuzotendeukira kune vanogadzira michina, avo vakashandura zvigadzirwa zvavo kuti zvienderane newaya dzealuminium.Vagadziri vewaya vakachinjawo zvigadzirwa zvavo, vachigadzira alloys matsva muAA-8000 akatevedzana, vachisanganisa simbi mumusanganiswa kuti vaderedze mafambiro ezvinokambaira.
Nekudaro, hapana chimwe cheizvi chinogona kuchengetedza aluminium mudunhu rebazi.Pakazosvika pakati pema1970, mazhinji emaseketi ebazi muchivako chitsva akanga asisashandisi aruminiyamu, asi yakanga isati yambokuvadzwa.Nzvimbo yekuisa aluminium wiring yakakura, uye dzimba dzenguva iyoyo dzaiongororwa zvakasimba nevaongorori vedzimba pavakachinja varidzi.Iyo fiasco yewaya dzealuminium yakaburitsa zvigadzirwa zvakasiyana-siyana kuderedza njodzi, kubva kune zvinodhura zvakanyanya zvinongedzo kusvika kune dzakakosha crimp dzinotonhora weld aluminium waya kune copper pigtails.Izvo zvakare sarudzo yekubvisa zvachose aluminium branch circuit wiring uye kuitsiva nemhangura, kunyange izvi zvinodhura uye zvinoparadza.
Kana masimba emusika achipokana neakanakisa maitiro einjiniya, kuedza kweindasitiri paaluminium kwakaratidza kuva chidzidzo chinodhura.
