Ib qho kev tiv thaiv overheat (tseem hu ua qhov hloov pauv kub lossis thermal protector) yog cov cuab yeej siv kev nyab xeeb siv los tiv thaiv cov cuab yeej los ntawm kev puas tsuaj vim overheating. Nws yog siv dav hauv kev lag luam xws li lub cev muaj zog, cov khoom siv hauv tsev, thiab cov khoom siv hauv tsev. Cov hauv qab no yog cov ncauj lus kom ntxaws txog nws cov ntawv thov tseem ceeb thiab cov haujlwm:
1. Lub luag haujlwm tseem ceeb
Kev ntsuas kub thiab kev tiv thaiv: Thaum cov khoom siv kub siab tshaj qhov chaw pib, lub Circuit Court raug txiav tawm kom tsis txhob overheating thiab puas.
Kev tiv thaiv overcurrent: Qee cov qauv (xws li KI6A, 2AM series) kuj muaj kev tiv thaiv kev tiv thaiv tam sim no, uas tuaj yeem cuam tshuam lub voj voog sai sai thaum lub cev muaj zog kaw lossis qhov tam sim no txawv txav.
Automatic/Manual reset
Tsis siv neeg rov pib hom: Lub zog yuav rov qab los tom qab qhov kub thiab txias (xws li ST22, 17AM series).
Phau ntawv rov pib hom: Yuav tsum tau phau ntawv kev cuam tshuam rov pib dua (xws li 6AP1 + PTC tus tiv thaiv), haum rau cov xwm txheej uas yuav tsum muaj kev nyab xeeb dua.
Dual tiv thaiv mechanism: Qee qhov tiv thaiv (xws li KLIXON 8CM) teb rau ob qho tib si kub thiab tam sim no hloov ib txhij, muab kev tiv thaiv ntau dua.
2. Cov ntawv thov tseem ceeb
(1) Lub cev muaj zog thiab cov khoom siv ua haujlwm
Txhua hom motors (AC / DC motors, dej twj tso kua mis, cua compressors, thiab lwm yam): Tiv thaiv winding overheating los yog blockage puas tsuaj (xws li BWA1D, KI6A series).
Cov cuab yeej hluav taws xob (xws li hluav taws xob laum thiab cutters): Tsis txhob siv lub cev muaj zog los ntawm kev ua haujlwm siab.
Kev lag luam tshuab (punch presses, tshuab cuab yeej, thiab lwm yam): Peb-theem lub cev muaj zog tiv thaiv, txhawb theem poob thiab kev tiv thaiv overload.
(2) Cov khoom siv hauv tsev
Cov khoom siv hluav taws xob cua sov (lub tshuab hluav taws xob hauv dej, qhov cub, hluav taws xob hluav taws xob): Tiv thaiv kom qhuav kub lossis kub tsis muaj kev tswj hwm (xws li KSD309U high-temperature protector).
Cov khoom siv hauv tsev me (cov tshuab kas fes, cov kiv cua hluav taws xob): Tsis siv neeg hluav taws xob tiv thaiv hluav taws xob (xws li bimetallic strip kub keyboards).
Cua txias thiab tub yees: Compressor overheat tiv thaiv.
(3) Cov khoom siv hluav taws xob thiab teeb pom kev zoo
Transformers thiab ballasts: Los tiv thaiv overload los yog tsis zoo cua sov dissipation (xws li 17AM series).
LED teeb: Tiv thaiv hluav taws los ntawm overheating ntawm lub tsav tsheb.
Roj teeb thiab charger: Saib xyuas qhov kub thiab txias kom tiv thaiv lub roj teeb thermal runaway.
(4) Automotive electronics
Lub qhov rais lub cev muaj zog, wiper lub cev muaj zog: Txhawm rau tiv thaiv cov rotor kaw lossis cua sov thaum lub sijhawm ua haujlwm ntev (xws li 6AP1 tus tiv thaiv).
Hluav taws xob lub tsheb them qhov system: xyuas kom muaj kev nyab xeeb kub thaum lub sijhawm them nyiaj.
3. Kev xaiv qhov tseem ceeb
Kev khiav hauj lwm kub: Qhov ntau yam yog 50 ° C mus rau 180 ° C. Kev xaiv yuav tsum yog raws li cov khoom yuav tsum tau (piv txwv li, hluav taws xob dej rhaub feem ntau siv 100 ° C mus rau 150 ° C).
Tam sim no / Voltage specification: xws li 5A / 250V los yog 30A / 125V, nws yuav tsum tau ua kom haum cov load.
Rov pib dua txoj kev: Tsis siv neeg rov pib dua yog tsim rau cov cuab yeej ua haujlwm tsis tu ncua, thaum phau ntawv rov pib dua yog siv nyob rau hauv cov xwm txheej muaj kev ruaj ntseg.
Kev xaiv cov khoom tiv thaiv overheat yuav tsum ua tib zoo xav txog qhov kub thiab txias, qhov ntsuas hluav taws xob, cov txheej txheem kev teeb tsa thiab ib puag ncig yuav tsum tau ua kom muaj kev nyab xeeb thiab txhim khu kev qha ntawm cov khoom siv.
