PTC thermistor alloy xov hlau rau Temperature Sensitive Resistance
PTC thermistor alloy xov hlau rau Temperature Sensitive Resistance
PTC Alloy hlau muaj qhov nruab nrab resistivity thiab siab zoo kub coefficient ntawm kuj. Nws yog dav siv nyob rau hauv ntau yam cua sov. Nws tuaj yeem tswj tau qhov kub thiab txias thiab kho lub zog los ntawm kev ua kom tsis tu ncua thiab txwv tam sim no.

PTC thermistor alloy hlau pom daim ntawv thov hauv ntau qhov chaw vim nws cov yam ntxwv tshwj xeeb. Nov yog qee qhov kev siv ntawm PTC thermistor:
- Kev tiv thaiv overcurrent: PTC thermistor yog dav siv hauv hluav taws xob circuits rau kev tiv thaiv overcurrent. Thaum lub siab tam sim no ntws los ntawm PTC thermistor, nws qhov kub thiab txias nce, ua rau qhov tsis kam nce sai. Qhov kev nce hauv qhov kev tiv thaiv no txwv tsis pub cov dej ntws tam sim no, tiv thaiv Circuit Court los ntawm kev puas tsuaj vim yog qhov tam sim no ntau dhau.
- Kev ntsuas kub thiab tswj: PTC thermistor yog siv los ua qhov ntsuas kub hauv cov ntawv thov xws li ntsuas kub, HVAC systems, thiab ntsuas ntsuas kub. Qhov tsis kam ntawm PTC thermistor hloov nrog qhov kub thiab txias, tso cai rau nws kom paub meej thiab ntsuas qhov ntsuas kub hloov pauv.
- Kev tswj tus kheej cov cua sov: PTC thermistor yog ua hauj lwm hauv tus kheej tswj cov cua sov. Thaum siv hauv cov cua sov, PTC thermistor qhov tsis kam nce nrog qhov kub thiab txias. Raws li qhov kub thiab txias, qhov tsis kam ntawm PTC thermistor kuj nce, ua rau txo qis hauv cov zis hluav taws xob thiab tiv thaiv kev kub dhau.
- Lub cev muaj zog pib thiab kev tiv thaiv: PTC thermistor yog siv nyob rau hauv lub cev muaj zog pib circuits kom txwv tsis pub muaj kev kub siab tam sim no thaum pib lub cev muaj zog. PTC thermistor ua raws li qhov txwv tam sim no, maj mam nce nws qhov kev tiv thaiv raws li qhov tam sim no ntws, yog li tiv thaiv lub cev muaj zog los ntawm qhov tam sim no ntau dhau thiab tiv thaiv kev puas tsuaj.
- Kev tiv thaiv pob roj teeb: PTC thermistor yog ua haujlwm nyob rau hauv cov roj teeb pob los tiv thaiv kev them nyiaj ntau dhau thiab overcurrent. Lawv ua raws li kev tiv thaiv los ntawm kev txwv cov dej ntws tam sim no thiab tiv thaiv kev tsim hluav taws xob ntau dhau, uas tuaj yeem ua rau cov roj teeb puas.
- Inrush tam sim no txwv: PTC thermistor ua hauj lwm raws li inrush tam sim no limiters hauv cov khoom siv fais fab thiab cov khoom siv hluav taws xob. Lawv pab txo qis qhov pib nce ntawm qhov tam sim no uas tshwm sim thaum lub tshuab hluav taws xob qhib, tiv thaiv cov khoom thiab txhim kho kev ntseeg tau.
Cov no tsuas yog qee qhov piv txwv ntawm cov ntawv thov uas siv PTC thermistor alloy hlau. Daim ntawv thov tshwj xeeb thiab kev txiav txim siab tsim qauv yuav txiav txim siab qhov tseeb alloy muaj pes tsawg leeg, daim ntawv zoo, thiab kev ua haujlwm tsis zoo ntawm PTC thermistor.
