Cov Khoom Tshwj Xeeb ntawm Resistance Hlau

Cov kab hlau tshwj xeeb ntawm kev tawm tsam feem ntau suav nrog cov ntsuas hluav taws xob xws li cov kab xaim hlau, tiv taus ntev thiab ntev. ‌

Cov lus qhia tshwj xeeb
Hlau txoj kab uas hla: Qhov taub lossis xaim cov taub ntawm cov hlau uas muaj zog yog ib qho tseem ceeb cov kev txwv tseem ceeb. Piv txwv li, cov hlau tawm nrog cov hlau xaim ntawm 1 hli muaj tus nqi tiv thaiv ntawm 1.3ω ib qho ntev ntawm 1. {19}} }.mm² \/ m. Ua tsis taus: resistivity (ρ) qhia cov khoom muaj peev xwm mus tabkaum. Lub calculation cov qauv yog r {{5} ρ} ρ ρ ρ ρ \/ s, qhov twg r sawv cev ntawm tus neeg xyuas pib, thiab sawv cev rau cov ntoo khaub lig-ntu. Ntev: Qhov ntev ntawm cov hlau ua hauj tsis tsis kam tseem cuam tshuam ntxiv nws tus nqi tiv thaiv kev tiv thaiv. Qhov ntev ntev, qhov ntau dua cov nqi tiv taus tus nqi. Cov kev qhia tshwj xeeb thiab cov qauv diam thiab ntev specifications: piv txwv li, ib pob nrog ib lub cheeb ntawm 3.2mm thiab ib qho ntev ntawm 9.5mm yog qhov haum rau kev voj voog. Ib pob nrog txoj kab uas hla ntawm 5 hli thiab ntev ntawm 12.5mm yog qhov haum rau cov voj voog high-fais fab voj voog. Lub Hwj Chim thiab Qhov Loj Specifications: Cov xov dej tsis taus ntawm lub zog sib txawv muaj ntau qhov sib txawv. Piv txwv li, qhov ntev ntawm 1 \/ 8w resistor yog 3.4 ± {23}} Thaum lub qhov ntev ntawm 5W resistor yog 24.5 ± 1mm ​​(l), 8.5 0 2.0mm (h).
