Xa uhlaziywa, abanye abantu baya kukhetha iingcingo ezinobukhulu obahlukeneyo ngokosetyenziso lwamandla.Nangona kunjalo, emva kokuba ukulungiswa kugqityiwe, ukugqithiswa kwesekethe kunye nezinye iingxaki zihlala zisenzeka.Iphi ke ingxaki?Isizathu esiphambili kukuba basebenzisa ucingo lwe-aluminiyam okanye i-copper-clad aluminiyam ucingo.Yintoni umahluko phakathi kocingo lobhedu kunye nocingo lwe-aluminiyam, kwaye zeziphi izinto ezingalunganga zokusebenzisa ucingo lwe-aluminium?Namhlanje ndiza kukuxelela ngayo.
I-aluminium yocingo yokuhlobisa ikhaya yayiqhelekile kwiindawo zasemaphandleni.Nangona kunjalo, ngokukhula kwamaxesha, ukuthandwa kwezixhobo zekhaya ezahlukeneyo kuye kwaba phezulu nangaphezulu kwiindawo ezisemaphandleni.I-aluminium yocingo yokuhlobisa ikhaya ayinakuthwala ukusetyenziswa kombane ngakumbi kwaye sele iphelile.Izixeko ezikhulu ezinosetyenziso oluphezulu lombane azifane zicinge ngeengcingo ze-aluminiyam.
Ke, kutheni kufuneka sisebenzise ucingo lobhedu ukuhombisa endaweni yocingo lwe-aluminiyam olungabizi kakhulu?
Isizathu 1: Ukuthwala okuphantsi
Njengoko sele kukhankanyiwe ngasentla, esinye sezizathu zokuba iingcingo ze-aluminiyam zipheliswe ngumthamo ophantsi wokuthwala: umlinganiselo wokukhetha iingcingo kukuthwala umthamo wocingo – ngomthamo wokuthwala, singakwazi ukubala ukuba ubungakanani bocingo olufunekayo ukuthwala njalo. yangoku kakhulu.
Umthamo wokuthwala wocingo lwe-aluminiyam yi-1/3~2/3 yocingo lobhedu.Ngokomzekelo, kwi-4 ye-square wire, ukuba ingundoqo yobhedu, umthamo wokuthwala umalunga ne-32A;ukuba ingundoqo ye-aluminium, umthamo wokuthwala umalunga ne-20A kuphela.
Ngoko ke, xa sithetha ukuba isiphaluka esithile sidinga i-4 square metres yeengcingo, sithetha ukuba zonke ziyi-copper cores, ezinokuthwala i-32A yangoku.Ngeli xesha, akwanele ukubeka i-4 square metres yocingo lwe-aluminium kunye nomthamo wokuthwala we-20A kuphela.Ukongeza, ukuba kufuneka usebenzise iingcingo ezinkulu ze-aluminiyam endaweni yeengcingo zobhedu, iityhubhu zocingo ezifunekayo ekufakeni imisonto nazo ziya kuba nkulu kwaye indawo efunekayo iya kuba nkulu, ngoko iindleko zokubeka aziyi kuba ngaphantsi kunokusebenzisa iingcingo zobhedu.Ezininzi.
Isizathu 2: Ukudibanisa i-Copper-aluminiyam yonakaliswa lula
Ngethuba nje kukho iingcingo ze-aluminium ekhaya, ngokuqinisekileyo kuya kubakho iindawo apho ubhedu kunye ne-aluminium zidibaniswe.Ubhedu kunye ne-aluminium zidibene ngokuthe ngqo.Emva kokusetyenziswa kombane, ukusabela kweekhemikhali njengebhetri ephambili kuya kwenzeka: i-aluminium esebenzayo ngakumbi iya kukhawulezisa i-oxidation, ibangela ukuba ama-joints ukuba Umthamo wangoku wokuthwala uphantsi de ugqithise ubuninzi, nto leyo enye yezizathu ezithe ngqo zokuba kutheni iingozi zihlala zenzeka usebenzisa iingcingo ze-aluminiyam.
Esona sizathu sokuba abantu abaninzi basasebenzisa iingcingo ze-aluminiyam kungenxa yexabiso eliphantsi.Nangona kunjalo, ukonyuka kweendleko zokwakha xa ubeka iingcingo ze-aluminiyam okanye iindleko zokulondolozwa kamva kunye nokusetyenziswa kwamandla aphezulu kulula ukubonwa xa kuthelekiswa nokusebenzisa iingcingo zobhedu.Inzuzo idlula ilahleko, singasathethi ke ngemiba yokhuseleko kunye neengozi ezifihlakeleyo ezibangelwa kukusebenzisa ucingo lwe-aluminium.
