Indlela ukukhetha icandelo intambo xa iintambo?

Ophezulu ezikumgangatho kunye nokufakelwa kakuhle baya kusoloko kunceda kukhuselwe naliphi na igumbi of "izimanga 'erhabaxa enxulumene kunye nemisinga elifutshane-wesiphaluka, yokugquma nokwaphuka, Ukudinwa iintambo zombane, izixhobo zombane umlilo kunye nezinye izinto. Ziphephe iimeko ezinjalo ezingemnandi kunye nezehlo kangangoko kunokwenzeka. Ukuze wenze oku, kufuneka ekuqaleni sinikele ingqalelo kuyo eli candelo le ntambo.

Abantu abaninzi abaye bagqiba ukwenza kweentambo zabo ngaphandle koncedo iingcali musa ukuqonda ngokupheleleyo ukubaluleka kwale nkqubo, apho aya icandelo cable umnqamlezo ekhethiweyo. Kwanokuba ngokusebenzisa ubuchwepheshe ezintsha mihla kungonga ukusuka iingxaki zingasentla, ukuba ekhethiweyo ngokungachanekanga icandelo lwangoku oqhuba intambo.

Xa inkqubo yokukhetha icandelo kuyimfuneko ukuba ithathele ingqalelo yonke imiba: ubukhulu kunye nexesha wolayisho, umsinga rated, nto leyo iya kubanjwa intambo, ubuninzi kunye ombane ubuncinane, amandla umthwalo. Kuyimfuneko ukukhangela uxhathiso kumqhubi amaqondo obushushu aphezulu (afana okusingqongileyo kunye nobushushu ngenxa short circuit), amandla ngoomatshini kunye nokumelana kumonakalo kunokwenzeka lwangaphandle. Alithandabuzeki elokuba, icandelo cable ixhomekeke nje kuphela ezi mpawu zingasentla kunye parameters. Kuyimfuneko ukuba ukuthatha ingqalelo umehluko ngabanye kunye nokufakelwa, kunye nempembelelo yemeko ezisingqongileyo kwaye imiba yayo nombhexeshi.

Eyona nto ibalulekileyo kwicandelo yokhetho le ntambo ethembakeleyo, umgangatho. Apha ukhetho best ukuze kuchazwe zezobhedu. Kuyinto kakhulu ukumelana neziphumo ezibi ezidweliswe ngasentla, kunokuba iintambo aluminium ngakumbi. umqhubi sobhedu iya kuba nempumelelo ngakumbi, yaye kuyinto efanele kakhulu kwiinkqubo deformation kunye namachibi. Ngenxa yoko, indawo yecandelo of cable sobhedu kuya kuba ngaphantsi kunolo-aluminiyam, ukuba ungubani nezinye iimpawu. Nakuba kuphela abangaboniyo umqhubi sobhedu siya kukhangela ngcono.

Ukukhetha Intambo cross-icandelo amandla, kufuneka ithathele ingqalelo amandla lilonke zonke izixhobo kunokwenzeka. Oku kubaluleke kakhulu. Kakade ke, kulula ngakumbi ukuba ukhethe intambo cross-icandelo esima. Kwakhona uthathe ingqalelo ubude bayo kunye namathuba zokulahleka ombane.

Igama elithi "icandelo cable" ubizwa ngokuba kwicandelo layo umnqamlezo. Electrical Engineering kokuba ugqibe parameters uyilo ezininzi: iimeko zokufudumeza lomntu, iimeko amandla ngoomatshini kwiZiko kwezoqoqosho obuqikelelwayo ingxinano ekhoyo ngoku.

Xa sithetha nje ngokubanzi, eli ubalo oluchanekileyo kufuneka kuthetha ubukho zezibalo. Kodwa ke, ungakwazi ukuthatha ithuba ukubala ezizodwa angundoqo parameters ukuba ukhethe i candelo intambo: amandla, ngoku, ngamanye amaxesha ombane unikezelo. Ezi theyibhile zingafunyanwa abalawuli nezixhobo yokufaka electrotechnical. Kukho banikwa iinkcukacha sele kubalwa ngenxa ezahlukeneyo intambo cross-icandelo ezenziwe ngezinto ezahlukeneyo, kuthathelwa ingqalelo zonke izinto kunokwenzeka. Kwakhona wabonisa zentsulungeko imiba nokulungiswa, ezifana kwesidingo sokusebenzisa intambo kumaqondo obushushu aphantsi.
