Cov Khoom Siv Tiv Thaiv Xob laim: Ib Lub Khoom Siv Tiv Thaiv Hluav Taws Xob Tseem Ceeb

Ib lub cuab yeej tiv thaiv xob laim, tseem hu ua lub cuab yeej tiv thaiv hluav taws xob, yog ib qho khoom siv tiv thaiv tseem ceeb hauv cov tshuab hluav taws xob thiab cov voj voog hluav taws xob. Nws lub luag haujlwm tseem ceeb yog hloov cov hluav taws xob siab tsis zoo - xws li cov uas tshwm sim los ntawm xob laim lossis cov khoom siv ua haujlwm tsis zoo - kom deb ntawm cov khoom siv rhiab heev thiab kom muaj kev nyab xeeb rau hauv av, tiv thaiv kev puas tsuaj lossis kev tawg.

Ua los ntawm cov khoom siv tseem ceeb, cov khoom siv tiv thaiv xob laim feem ntau muaj cov resistor tsis-linear (feem ntau ua los ntawm hlau oxide, zoo li zinc oxide), ob lub electrodes, thiab lub tsev rwb thaiv tsev. Lub resistor tsis-linear yog lub plawv ntawm lub cuab yeej: nws muaj kev tiv thaiv siab heev nyob rau hauv qhov hluav taws xob ua haujlwm ib txwm muaj, ua kom tsis muaj kev ntws tam sim no tsis tsim nyog thiab ua kom lub zog hluav taws xob ruaj khov. Txawm li cas los xij, thaum muaj hluav taws xob txaus ntshai tshwm sim, nws qhov kev tiv thaiv poob qis, tsim txoj hauv kev tsis kam rau hluav taws xob kom hla dhau cov khoom siv txuas nrog thiab tso tawm mus rau hauv av.

Cov cuab yeej ntes xob laim siv dav dav hauv ntau qhov xwm txheej. Hauv cov phiaj xwm fais fab, lawv tiv thaiv cov transformers, cov kab xa hluav taws xob, thiab cov chaw hloov pauv los ntawm kev nce siab los ntawm xob laim. Hauv cov tsev nyob thiab cov tsev lag luam, cov cuab yeej ntes me me tiv thaiv cov khoom siv hauv tsev, HVAC systems, thiab cov khoom siv sib txuas lus. Txawm tias nyob rau hauv cov chaw ua haujlwm, lawv tiv thaiv cov tshuab precision thiab cov kab ke tswj hwm los ntawm kev nce siab ntawm hluav taws xob uas tuaj yeem cuam tshuam kev tsim khoom.

Cov cuab yeej ntes xob laim niaj hnub no, tshwj xeeb tshaj yog cov hlau oxide variants, muaj cov txiaj ntsig zoo li me me, tsis tas yuav tsum tau saib xyuas tas li, thiab muaj peev xwm sib xws nrog hluav taws xob dav. Tsis zoo li cov cuab yeej ntes hluav taws xob qub, lawv teb sai dua rau cov hluav taws xob surges, muab kev tiv thaiv zoo dua. Kev teeb tsa kom zoo - suav nrog kev sib txuas hauv av ruaj ntseg thiab kev sib phim voltage - yog qhov tseem ceeb kom ntseeg tau tias cov cuab yeej ntes hluav taws xob ua haujlwm tau zoo, ua rau nws yog qhov kev tiv thaiv tseem ceeb rau kev tswj hwm kev ntseeg siab thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob.
