    PTC thermistor alloy xaim pom cov ntawv thov hauv ntau daim teb vim nws cov yam ntxwv tshwj xeeb. Nov yog qee qhov kev siv ntawm PTC cov cua nab:

    Kev Tiv Thaiv Kev Tiv Thaiv Ntau Tshaj: PTC tus mob kub tau siv dav hauv hluav taws xob cov hluav taws xob rau overcurent tiv thaiv. Thaum ib tug siab tam sim no ntws los ntawm PTC thermistor, nws kub nce ntxiv, ua rau muaj kev tiv taus kom sai. Qhov kev nce no nce rau kev tiv thaiv qhov khiav tawm tam sim no, tiv thaiv cov Circuit Court ntawm kev puas tsuaj vim muaj kev puas tsuaj ntau.

    Qhov kub thiab txias thiab tswj: PTC cov cua nab yog siv cov ntsuas kub hauv kev siv xws li cov ntsuas cua sov, hvac system, thiab ntsuas kub. Qhov tsis kam ntawm PTC thermistor hloov nrog qhov kub, cia nws kom nws kom raug thiab ntsuas kub hloov.

    Kev tswj hwm tus kheej tswj kev kub taub hau: PTC cov cua nab yog ua haujlwm hauv kev tswj hwm tus kheej kev tswj hwm cua sov. Thaum siv nyob rau hauv cov cua sov, PTC thermistor qhov kev tawm tsam nce nrog qhov kub. Raws li qhov kub nce, qhov tsis kam ntawm PTC tus cua kub kuj nce, ua rau kom txo qis hauv lub zog tawm thiab tiv thaiv kev siv zog.

    Kev Tsav Tsheb Pib thiab Kev Tiv Thaiv: PTC Tus Phooj Ywg Raug Siv Hauv Lub Cev Muaj Zog Tsheb pib los txwv qhov siab inrush tam sim no thaum lub cev muaj zog. Lub PTC tus cua nab ua ua raws li lub neej tam sim no, maj mam nce nws qhov kev tawm tsam tam sim no, yog qhov kev tiv thaiv lub cev muaj zog thiab tiv thaiv kev puas tsuaj.

    Roj teeb pob tiv thaiv: PTC tus mob ua haujlwm tau ua haujlwm hauv cov roj teeb pob los tiv thaiv tawm tsam kev tshaj tawm thiab cov xwm txheej overcurring. Lawv ua raws li kev tiv thaiv kev tiv thaiv los ntawm kev txwv qhov khiav tawm tam sim no thiab tiv thaiv kom ntau dhau lub tshav kub hlwb, uas tuaj yeem ua rau cov roj teeb hlwb.

    Inrush txwv tam sim no: PTC tus mob kub ua haujlwm pab raws li Inrush tam sim no txwv cov khoom siv hluav taws xob thiab khoom siv hluav taws xob. Lawv pab txo qhov pib tawm ntawm qhov tam sim no uas tshwm sim thaum muab hluav taws xob tig rau, tiv thaiv cov cheebtsam thiab txhim kho kev ntseeg tau.

    Cov no tsuas yog qee qhov piv txwv ntawm cov ntawv thov uas PTC cov cua nab kuab siv tau siv. Daim ntawv thov tshwj xeeb thiab kev txiav txim siab tsim qauv yuav txiav txim siab kom paub meej tag nrho cov pes tsawg leeg, daim ntawv ua haujlwm ntawm PTC thermistor.
