Hauv tsab xov xwm no, peb piav qhia luv luv vim li cas vim li cas qhov kub thiab txias ntawm PTC rhaub thermistor ntawm lub zog tshiab (hluav taws xob) tsheb yog siab. Ua ib lub chaw tsim khoom ntawm PTC cov cua sov thiab cov cua sov lub zog, peb yuav sim peb qhov zoo tshaj plaws los npaj thiab tshaj tawm txhua hom kev paub txog kev paub, peb yuav pab koj tag nrho.
Qhov siab dua qhov kub ntawm PTC thermistor, qhov siab dua qhov hluav taws xob thiab qhov siab dua tam sim no, tab sis qhov qis dua tus nqi kuj, uas yuav sai sai ua rau lub thermal tawg ntawm PTC thermistor. Qhov ua rau ntawm PTCR hluav taws xob rhaub tawg yog feem ntau muab faib ua: grain ciam tawg thiab thermal tawg. Grain boundary breakdown: Vim muaj qhov txawv txav ntawm qee cov nplej los yog tsis sib xws ntawm cov nplej, qhov hluav taws xob ntawm qee thaj tsam ntawm cov nplej loj dhau. Qhov kev puas tsuaj los ntawm lub pob hluav taws xob yog hu ua grain ciam tawg.
Xyoo 1963, G. Goodman tau taw qhia tias ib leeg-crystal BaTiO3 ib qho khoom siv hluav taws xob tsis pom PTC nyhuv, thaum polycrystalline BaTiO3 ceramics muaj PTC nyhuv tom qab doping. Txij thaum ntawd los, PTC feem ntau muab faib ua ib thaj tsam ntawm lub ntiaj teb. Hauv PTC cov khoom, cov khoom siv lead ua yog cov khoom siv semiconductor, thiab cov ciam teb yog ib txheej insulating, uas yog, muaj peev xwm thaiv tau. Sab nraud hluav taws xob teb yog tsuas yog siv rau cov lis ciam txheej.
Lub tshuab hluav taws xob boiler tau muab faib ua ob hom: hom dej cia thiab hom cua sov ceev. Lub ntsiab sib txawv ntawm ob yog: cov dej cia hluav taws xob boiler system siv lub rhaub dej hauv lub tshuab hluav taws xob boiler kom sov dej, thiab tom qab ntawd cov dej kub hauv cov dej kub cia tank yog siv rau cua sov System cua sov; lub tshuab hluav taws xob hluav taws xob ceev ceev tsis muaj lub tank kub cia, thiab cov dej yog cua sov ncaj qha rau cov cua sov. Nws tuaj yeem ntsia tau rau hauv chav ua noj, lub sam thiaj, hauv qab daus lossis qab nthab. Lub pob hluav taws xob hluav taws xob txuas nrog lub tshuab hluav taws xob los ntawm cov kav dej hauv tsev, uas tuaj yeem paub txog cov khoom siv hluav taws xob ntawm cov cua sov thiab cov dej kub hauv tsev tib lub sijhawm. Tom qab txhim kho lub ntsuas kub hauv tsev, koj tuaj yeem kho qhov kub ntawm chav sib txawv ntawm qhov xav tau; Koj tsuas yog yuav tsum tau teeb tsa hauv" tsis tshua muaj kub thiab tiv thaiv tsis khov" xeev thaum tsis muaj leej twg nyob hauv tsev; lub sijhawm pib ua haujlwm tuaj yeem raug preset, thiab koj tuaj yeem hnov qhov sov so hauv tsev tam sim tom qab rov qab los tsev. Cov neeg tsim khoom tuaj yeem txuag lub peev, av, thiab tib neeg cov peev txheej siv rau kev tsim kho, kev npaj, thiab kev saib xyuas chav boiler; txo cov pa phem.
