PTC thermistor alloy wire pom kev siv rau ntau qhov chaw vim nws cov yam ntxwv tshwj xeeb. Nov yog qee qhov kev siv PTC thermistors:

Kev tiv thaiv overcurrent: PTC thermistors siv dav hauv cov hluav taws xob circuits rau kev tiv thaiv overcurrent. Thaum muaj hluav taws xob ntau ntws los ntawm PTC thermistor, nws qhov kub nce ntxiv, ua rau qhov kev tiv thaiv nce sai. Qhov kev nce ntxiv ntawm qhov kev tiv thaiv no txwv qhov ntws tam sim no, tiv thaiv lub circuit ntawm kev puas tsuaj vim muaj hluav taws xob ntau dhau.

Kev ntsuas kub thiab kev tswj: PTC thermistors yog siv los ua cov ntsuas kub hauv cov ntawv thov xws li thermostats, HVAC systems, thiab cov khoom siv saib xyuas kub. Qhov tsis kam ntawm PTC thermistor hloov pauv nrog qhov kub, ua rau nws tuaj yeem ntsuas thiab ntsuas qhov kub sib txawv.

Cov cua sov uas tswj tus kheej: Cov thermistors PTC siv rau hauv cov khoom cua sov uas tswj tus kheej. Thaum siv rau hauv cov cua sov, qhov tsis kam ntawm PTC thermistor nce nrog rau qhov kub thiab txias. Thaum qhov kub nce, qhov tsis kam ntawm PTC thermistor kuj nce ntxiv, ua rau lub zog tso zis txo qis thiab tiv thaiv kom tsis txhob kub dhau.

Kev pib thiab kev tiv thaiv ntawm lub cev muaj zog: Cov thermistors PTC siv rau hauv cov voj voog pib ntawm lub cev muaj zog los txwv cov hluav taws xob siab thaum lub sijhawm pib ntawm lub cev muaj zog. Lub thermistor PTC ua haujlwm ua tus txwv tam sim no, maj mam ua rau nws qhov kev tiv thaiv nce ntxiv thaum cov hluav taws xob ntws, yog li tiv thaiv lub cev muaj zog ntawm cov hluav taws xob ntau dhau thiab tiv thaiv kev puas tsuaj.

Kev tiv thaiv lub roj teeb: Cov thermistors PTC siv rau hauv cov roj teeb los tiv thaiv kev them ntau dhau thiab cov xwm txheej overcurrent. Lawv ua haujlwm ua kev tiv thaiv los ntawm kev txwv cov dej ntws tam sim no thiab tiv thaiv kev tsim cua sov ntau dhau, uas tuaj yeem ua rau lub roj teeb puas tsuaj.

Kev txwv tam sim no nkag: PTC thermistors ua haujlwm ua cov kev txwv tam sim no nkag hauv cov khoom siv fais fab thiab cov khoom siv hluav taws xob. Lawv pab txo qhov pib nce ntawm tam sim no uas tshwm sim thaum lub zog fais fab qhib, tiv thaiv cov khoom thiab txhim kho kev ntseeg siab ntawm lub kaw lus.

Cov no tsuas yog ob peb yam piv txwv ntawm cov ntawv thov uas siv PTC thermistor alloy wire. Cov kev xav txog daim ntawv thov thiab kev tsim qauv tshwj xeeb yuav txiav txim siab qhov sib xyaw ua ke, cov qauv, thiab cov kev ua haujlwm ntawm PTC thermistor.
