Kev tiv thaiv tus kheej ntawm kev hloov cov khoom siv hluav taws xob
Hloov fais fab mov kom ntev li lub hwj chim tsis ua hauj lwm, txawm lub teb chaws tsis tau mus kawm ntawv tus poj niam laus paub pom tias lub fuse yog cua tshuab, hais txog lub fuse ntawm qhov teeb meem no zoo li cuaj xyoo ntawm kev kawm yuam. Qhov no ntawm ib sab qhia tau hais tias lub luag hauj lwm tiv thaiv fuse muaj zog heev, lwm lub ntsiab lus tseem qhia tau hais tias lub zog hloov hluav taws xob fuse muaj ntau heev, hnub no peb yuav tham txog kev qhib lub zog hloov hluav taws xob. Hloov fais fab mov rau hauv kab ua ntej hauv koob nrog lub fuse, uas tsis tas yuav hais ntau peb txhua tus paub, tsom mus rau ib qho tseem ceeb hauv qab nws, txuas nrog hauv series hauv fuse. Tom qab lub inlet kab ntawm ob kab ntawm varistor, thawj kev sib cuag yuav muaj ib tug illusion, ib tug fuse yuav overcurrent tiv thaiv, tab sis kuj kom tau ib tug redundant varistor, qhov no tiv thaiv mechanism ntawm lub hwj chim mov, hais ob peb lo lus hais txog tej yam. zais tom qab lub fuse.
Ntawm lub varistor, kuv luv luv tham txog ob peb yam ntxwv: Ua ntej, cov yam ntxwv ntawm qhov voltage ntau nws tso cai rau tiv taus, nws yog infinite kuj, ib zaug nws tshaj qhov ntau ntawm qhov voltage nws withstands, nws yuav luag tsis muaj kev tiv thaiv, sib npaug. luv luv-circuit, siv cov yam ntxwv no tsuas yog los txiav txim nws zoo los yog phem, nyob rau hauv ib txwm muaj xwm txheej, nws yog ib tug loj heev tus nqi ntawm cov kuj, nyob ze rau infinity, yog hais tias qhov ntsuas rau tus nqi ntawm cov kuj yog heev me me, qhia tias varistor puas lawm. Qhov thib ob, qhov varistor teb ceev ceev heev, los ntawm infinity mus rau conduction lub sij hawm luv luv, yog li koj tuaj yeem tiv thaiv Circuit Court sai sai. Thib peb, nws cov kev xaiv, vim hais tias lub ncov AC voltage thiab qhov tseeb qhov zoo voltage tus nqi ntawm kev sib raug zoo ntawm tus nqi yog tsis zoo li qub, yog li kev xaiv ntawm qhov ntsuas voltage ntawm varistor rau qhov xav tau los tiv thaiv qhov voltage 2.4 npaug los yog li ntawd, siv qhov taw tes no, koj tuaj yeem kwv yees qhov tam sim no ntawm Circuit Court nws ua haujlwm nyob rau hauv lub overhaul.
Thaum kawg, nws tsis yog ib tug neeg dig muag looj tsom iav dub, rov qab los tham txog qhov teeb meem no?
Ua ke nrog ob peb lub ntsiab lus ntawm varistor, nws yog ib qho yooj yim to taub yog vim li cas lub fuse yuav tsum tau siv ua ke nrog lub varistor, lub fuse yog kev cob cog rua nyob rau hauv series nyob rau hauv lub Circuit Court, varistor lub fuse yog kev cob cog rua nyob rau hauv series nyob rau hauv lub Circuit Court, lub varistor txuas nrog. nyob rau hauv parallel nyob rau hauv lub Circuit Court, lawv muaj sib txawv kev faib ua hauj lwm, ib tug tiv thaiv lub overcurrent, ib tug tiv thaiv lub overvoltage, thaum lub overvoltage, lub varistor instantly luv tawm, ua rau ib tug siab tam sim no, hlawv lub fuse, lub hwj chim tsis ua hauj lwm tiv thaiv. Thaum overvoltage, lub varistor tam sim luv-circuit, uas ua rau lub siab tam sim no, hlawv tawm lub fuse, lub hwj chim tsis ua hauj lwm los tiv thaiv Circuit Court, ob leeg yog ywj siab ntawm ib leeg, tab sis kuj ua hauj lwm ua ke.
Hais txog ntawm no yuav tsum tau hais txog qhov tshwm sim, qee qhov hloov hluav taws xob fuse tshuab, hloov lub fuse thiab siv ib txwm, pom tseeb tsis muaj qhov txhaum tab sis lub fuse tau tshuab. Cia tus neeg xav tias tsis muaj laj thawj thiab tsis paub meej, qhov tseeb, nws yuav yog qhov tsis txaus ntseeg tam sim no, varistors ua lub luag haujlwm tiv thaiv hauv lub fuse, thiab nws tus kheej hluav taws xob Circuit Court tsis muaj teeb meem, qhov no yog lub Circuit Court ntawm kev tiv thaiv tus kheej.
