Kev tu txhua hnub ntawm PTC rhaub
PTC yog cov ntawv luv ntawm Positive Temperature Coefficient, uas txhais tau hais tias qhov kub thiab txias coefficient, feem ntau zoo kub coefficient yog cov khoom siv semiconductor loj heev lossis cov khoom siv. Feem ntau peb hais PTC yog qhov zoo kub coefficient thermistor, hu ua PTC thermistor.
PTC thermistor yog qhov ntsuas kub-sensitive semiconductor resistor. Thaum qhov kub siab tshaj qhov ntsuas kub (Curie kub), nws tus nqi kuj nce mus nce qib raws li qhov kub nce.
PTC thermistors tau muab faib ua ceramic PTC thermistor thiab organic polymer PTC thermistor raws li lawv cov khoom sib txawv.
PTC thermistors tau muab faib ua PTC thermistor rau tsis siv neeg degaussing, PTC thermistors rau qeeb pib, PTC thermistors rau qhov kub thiab txias, PTC thermistors rau kev tiv thaiv overcurrent, thiab PTC rau kev tiv thaiv overheating. PTC Thermistor rau Thermistor thiab Sensor.
Ua tib zoo saib xyuas qhov nruab nrab cua sov thaum xaiv PTC cov cua sov. Tsis muaj kev cuam tshuam corrosion rau cov khoom siv hluav taws xob cua sov raj thiab lub plhaub. PTC rhaub tau siv rau lub sijhawm ntev. Yog tias muaj cov yeeb nkab tuab thiab roj rau ntawm qhov chaw, lawv yuav tsum tau muab tshem tawm raws sijhawm. Txwv tsis pub, lub tshav kub hloov pauv ntawm cov hluav taws xob cua sov yeeb nkab yuav raug txo kom tsawg thiab cov cua kub ntawm cov yeeb nkab saum npoo yuav dhau qhov ntsuas qhov kev puas tsuaj. PTC rhaub yuav tsum tau muab cia rau hauv ib pawg qhuav. Yog tias qhov chaw ntub dej vim qhov chaw ruaj khov, siv lub megohmmeter los ntsuas cov rwb thaiv tsev. Yog tias nws tsawg dua 1 megohm / 500 volts, lub raj cua sov yuav tsum muab tso rau hauv 200 degree qhuav lub thawv kom qhuav.
Raws li hom tshiab ntawm cov khoom siv thermistor, PTC cov cua sov tuaj yeem muab faib ua ob pawg loj: hloov thiab ua npaws. Kev siv cov khoom siv PTC muaj cov yam ntxwv ntawm kev kub siab, kev txwv tam sim no, ncua sij hawm, thiab lwm yam thiab tsis muaj kev sib cuag, tsis muaj suab nrov thiab ua haujlwm ntev. Nws tuaj yeem siv rau kev pib lub tub yees, kev tiv thaiv lub cev muaj zog, kev tiv thaiv kev sib hloov tshuab, kev tiv thaiv yoov tshaj cum, curling plaub hau Cov khoom siv hauv tsev me xws li cov plaub hau irons thiab hluav taws xob irons. Siv cov yam ntxwv ntawm consolidating kub taub hau hom PTC muaj nuj nqi, cua kub ceev, thiab tsawg cuam tshuam los ntawm lub hwj chim mov voltage fluctuations, ntau yam khoom cua sov ua tau los ua ib tug heev aspirational hloov khoom rau hlau kuj hlau kub cov ntaub ntawv. Tam sim no, nws tau siv dav hauv cov tshuab cua sov, cov tshuab ziab khaub ncaws, cua curtains, cua txias, thiab lwm yam.
