Nrog kev nce qib txuas ntxiv ntawm thev naus laus zis, qhov kev thov rau cov khoom siv hluav taws xob yog hnub loj zuj zus. Thiab ib qho ntawm cov khoom tseem ceeb, xaim hlau, ua lub luag haujlwm tseem ceeb. Cov xov hlau tseem ceeb yog siv los tswj hwm tam sim no thiab voltage, feem ntau pom nyob rau hauv ntau yam khoom siv hluav taws xob. Kab lus no yuav qhia txog cov xov xwm tshwj xeeb ntawm cov xov hlau tiv thaiv.

Hlau hlau yog ib tug hlau nyias ua los ntawm cov ntaub ntawv tshwj xeeb uas tuaj yeem tsim cov yam ntxwv tshwj xeeb. Nws ib txwm yog ua los ntawm cov hlau lossis alloys, xws li Nickel Chromium alloy, hlau siv tau cov kab sib txawv, ntev, thiab kev tawm tsam ntau.

Firstly, cia saib txoj kab uas hla ntawm cov hlau uas muaj zog. Lub taub yog qhov ntev ntawm kev sib tw kab hla ntu ntawm cov xaim hluav taws xob, feem ntau ntsuas hauv millimeters (hli). Qhov loj ntawm lub cheeb tsam cuam tshuam rau kev ua haujlwm ntawm cov kav hlau tawm tsam. Feem ntau, lub thinner txoj kab uas hla, qhov ntau dua cov tsis kam lees ntawm cov hlau tawm tsam; Lub thicker txoj kab uas hla, qhov me me ntawm cov nqi tiv thaiv ntawm cov hlau tawm. Yog li thaum xaiv hlau tsis kam, nws yog qhov yuav tsum tau txiav txim siab qhov taub loj raws li kev xav tau.

Thib ob, qhov ntev ntawm cov hlau uas tsis kam kuj tseem yog qhov tseem ceeb siv tau. Qhov ntev tau txiav txim siab qhov loj tag nrho ntawm cov hlau uas tsis kam, feem ntau ntsuas hauv meters (m). Qhov loj me ntawm qhov ntev yog feem ntau txiav txim los ntawm Circuit Tsim, thiab xaiv qhov ntev tsim nyog raws li qhov yuav tsum tau ua haujlwm ntawm cov lag luam tam sim no ntawm cov hlau tawm.

Thaum kawg, cov nqi tiv thaiv tsis kam ntawm cov xaim hluav taws xob yog ib qho kev ntsuas tub ntxhais. Tus nqi resistance sawv cev rau kev kawm ntawv ntawm kev tawm tsam ntawm cov hlau ua hauj hlau rau tam sim no, feem ntau ntsuas hauv OHMS (ω). Tus nqi tsis kam muaj peev xwm ua tiav los ntawm kev kho cov khoom, txoj kab uas hla, thiab ntev ntawm cov hlau tawm. Hauv cov ntawv thov siv, peb tuaj yeem ua tau raws li kev sib txawv ntawm cov xaim hluav taws xob los ntawm kev sib txuas cov xov hlau nrog kev sib txawv.

Ntxiv nrog rau peb qhov kev qhia tseem ceeb tau hais los saum toj no, tseem muaj lwm yam uas cuam tshuam rau kev ua tau zoo ntawm cov hlau tawm. Piv txwv li, cov ntaub ntawv xaiv muaj qhov cuam tshuam tseem ceeb ntawm kev ruaj khov thiab conductivity ntawm cov xov hlau; Kev kho deg tuaj yeem txhim kho lub corrosion tsis kam ntawm cov xov hlau; Qhov kub tshaj plaws kub kuj tseem muaj kev cuam tshuam rau kev ua haujlwm kev ua haujlwm ntawm cov xov hlau, thiab lwm yam.

Hauv cov ntsiab lus, kev xaiv ntawm cov hlau uas yuav tsum muaj kev txiav txim siab ntau yam ntawm ntau yam. Raws li cov kev yuav tsum tau sib txuas ua ke, txiav txim siab qhov tsim nyog txoj kab uas tsim nyog, thaum them nyiaj rau cov khoom siv ntawm cov khoom siv tawm ntawm cov khoom siv hluav taws xob.

Nrog kev nce qib txuas ntxiv ntawm thev naus laus zis, qhov kev thov rau cov xov hluav taws xob tiv thaiv hluav taws xob hauv cov khoom siv hluav taws xob tseem yog kev hloov zuj zus. Yav tom ntej, peb tuaj yeem ua rau cov xov dej tsis kam ua cov xov hlau yuav ua me, ruaj khov, thiab ua tau zoo dua. Seb nws cov smartphones, khoos phis tawj, tsheb, lossis lwm yam xov hlau, kev yooj yim dua thiab kev zoo siab rau tib neeg.

Qhov saum toj no yog kev taw qhia rau cov kev qhia tshwj xeeb thiab tsis ua raws li cov xov hlau. Kuv vam tias tsab xov xwm no tuaj yeem muab cov nyeem ntawv nkag siab tob txog kev tiv thaiv cov xov hlau thiab muab kev taw qhia hauv cov ntawv thov. Txawm hais tias cov xov hlau tiv thaiv me me, lawv ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, txhawb kev txhim kho thev naus laus zis thiab kev nce qib ntawm tib neeg. Cia peb tos ntsoov yuav tsim ntau qhov kev txhim kho ntawm kev txhim kho cov xov hluav taws xob hauv yav tom ntej!
