Cov chaw tsim khoom thiab cov chaw kho cov cav muaj ib qho kev txhawj xeeb zoo sib xws: cov cav siv sab nraum zoov, tshwj xeeb tshaj yog ib ntus, feem ntau muaj feem ntau dua ntawm cov teeb meem zoo. Qhov laj thawj yog tias cov xwm txheej ua haujlwm sab nraum zoov tsis zoo, nrog rau hmoov av, nag, thiab lwm yam pa phem cuam tshuam rau cov cav. Qhov teeb meem no hnyav zuj zus thaum qib kev tiv thaiv tsis raug xaiv kom raug.
Lwm qhov teeb meem tseem ceeb yog qhov kev puas tsuaj los ntawm kev ua haujlwm qis-voltage rau cov windings ntawm lub cev muaj zog. Txhua tus qauv lossis series ntawm lub cev muaj cov kev cai tshwj xeeb rau kev nyab xeeb voltage thiab zaus fais fab. Thaum tshaj qhov ntau tshaj, lub cev muaj zog yuav muaj teeb meem ntau dua. Ntau lub tuam txhab tsim khoom siv siv cov kev tiv thaiv, tab sis cov no feem ntau raug overridden, tawm hauv lub cev muaj zog ua haujlwm nyob rau hauv cov xwm txheej tsis zoo nrog qis-voltage thiab tsis muaj kev tiv thaiv.
Ib tug neeg sab hauv tau qhia tias rau kev ua haujlwm sab nraum zoov ib ntus, xav txog tus nqi, cov kab xa hluav taws xob qee zaum ntev, thiab cov xov hlau txhuas feem ntau siv hloov tooj liab los tiv thaiv kev tub sab. Ua ke nrog cov xwm txheej ua haujlwm, kev xa hluav taws xob, thiab tsis muaj kev ntsuas tiv thaiv,Cov cav tsis muaj zogua haujlwm nyob rau hauv ib puag ncig hnyav nrog lub zog qis thiab tsis muaj kev tiv thaiv, ua rau muaj qhov tsis paub meej txog qhov zoo.
Lub Cev Muaj Zog Tsis Muaj CoreKev Txuas Ntxiv Kev Paub:
- Kev Sib Piv ntawm Cov Hlau Aluminium thiab Tooj Liab
- Tooj liab tsis tshua muaj zog tab sis txhuas yaj sai dua. Tooj liab muaj kev coj hluav taws xob zoo dua thiab muaj zog dua.
- Aluminium pheej yig dua thiab sib dua tab sis nws muaj zog tsawg dua thiab yooj yim oxidation ntawm kev sib txuas, ua rau kub dua thiab tsis sib cuag zoo.
- Cov xov tooj liab muaj cov ductility zoo dua, lub zog, kev qaug zog, kev ruaj khov, thiab kev tiv thaiv corrosion.
- Kev tiv thaiv ntawm cov neeg coj ua
- Cov hlau yog cov uas feem ntau siv los ua hluav taws xob, nrog rau nyiaj muaj cov hluav taws xob zoo tshaj plaws. Lwm cov khoom uas muaj kev tiv taus siab hu ua cov insulators. Cov ntaub ntawv ntawm cov conductors thiab insulators yog semiconductors.
- Cov Khoom Siv Conductor
- Nyiaj, tooj liab, thiab txhuas yog cov khoom siv hluav taws xob zoo tshaj plaws hauv lawv lub xeev ntuj. Nyiaj kim heev, yog li tooj liab feem ntau siv. Aluminium siv dav hauv kev xa hluav taws xob vim nws qhov hnyav sib dua thiab tus nqi qis. Cov xov hlau txhuas uas muaj hlau cored siv los txhim kho lub zog. Nyiaj tsis tshua siv vim tus nqi, tsuas yog siv rau hauv cov ntawv thov uas xav tau ntau xws li cov cuab yeej precision thiab aerospace. Kub siv rau kev sib cuag hauv qee cov cuab yeej vim nws cov tshuaj ruaj khov, tsis yog nws qhov resistivity.
