Hauv thaj teb ntawm me me thiab nruab nrab-qhov loj me peb-theem asynchronous lub cev muaj zogs, xyuas kom muaj kev nyab xeeb thiab kev ua haujlwm yog qhov tseem ceeb. Ib txoj hauv kev zoo tshaj plaws kom ua tiav lub hom phiaj no yog siv kev tiv thaiv overheat thiab ntsuas kub. Ntawm lawv, PTC (zoo kub coefficient) thermistor tau dhau los ua kev xaiv nrov vim lawv cov yam ntxwv tshwj xeeb thiab qhov zoo.
PTC thermistor yog me me thiab zoo haum rau kev koom ua ke rau hauv lub cev muaj zog qhov twg qhov chaw txwv. Lawv lub peev xwm thermal tsawg tso cai rau cov lus teb ceev ceev, tso cai rau yuav luag tam sim nrhiav pom ntawm overheating. Lub sijhawm tiv thaiv sai no yog qhov tseem ceeb hauv kev tiv thaiv kev puas tsuaj rau lub cev muaj zog los ntawm kev tso cai rau kev cuam tshuam raws sijhawm ua ntej muaj kev ua tsis tiav loj.
Tsis tsuas yog cov thermistors zoo hauv kev saib xyuas qhov kub thiab txias, lawv kuj ua lub luag haujlwm tseem ceeb hauv ntau yam kev tiv thaiv kev ua haujlwm. Lawv feem ntau siv rau undervoltage, overvoltage, thiab overload tiv thaiv ntawm motors. Los ntawm kev soj ntsuam cov hluav taws xob tsis tu ncua, PTC thermistor tuaj yeem ua rau muaj kev tiv thaiv kev tiv thaiv thaum lawv pom cov xwm txheej uas tuaj yeem ua rau lub cev tsis ua haujlwm. Qhov kev tiv thaiv kev tiv thaiv no pab txuas ntxiv lub neej ntawm lub cev muaj zog thiab ua kom nws khiav tau zoo.
Tsis tas li ntawd, PTC thermistors ua lub luag haujlwm tseem ceeb hauv theem poob pib tiv thaiv. Hauv peb-theem asynchronous inductionac cevsystem, qhov poob ntawm ib theem tuaj yeem ua rau muaj teeb meem loj hauv kev ua haujlwm, nrog rau kev kub dhau thiab kev ntxhov siab ntawm cov neeg kho tshuab. Los ntawm kev siv PTC thermistors, lub cev muaj zog tuaj yeem tiv thaiv los ntawm cov xwm txheej zoo li no, kom ntseeg tau tias lawv ua haujlwm tsis zoo.
Nws yog ib qho kev coj ua zoo tshaj plaws los koom ua ke PTC thermistor rau kev tiv thaiv overheat thiab ntsuas kub hauv me me thiab nruab nrab-qhov loj me peb-theem asynchronous motors. Lawv yog cov me me, teb ceev ceev, thiab ntau yam, thiab yog cov khoom tseem ceeb rau kev ua kom ntseeg tauhluav taws xob lub cev muaj zogkev ua haujlwm thiab lub neej. Kev nkag siab txog cov khoom no yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev tsim lub cev muaj zog, kev saib xyuas, lossis kev ua haujlwm.
