Qhov fuze no ua haujlwm nrog cov nqi tawg lossis nrog lub caij nplooj ntoos hlav cocked thiab tus pas nrig uas tawm thaum qhov txuas tau yaj.
Tus pin thiab lub caij nplooj ntoos hlav yog parallel mus rau fusible txuas. Thaum qhov txuas melts, lub unloading mechanism yog qhib, ua rau tus pin ya tawm.
Hloov fuse
Hloov fuses yog ib hom hluav taws xob fuse uas tuaj yeem tswj tau los ntawm kev siv tus kov hloov.
Hauv kev siv ntau yam hauv qhov chaw muaj hluav taws xob siab, koj tswj xyuas seb lub fuses dhau lub zog lossis tsis yog los ntawm kev hloov pauv mus rau qhov chaw qhib lossis tawm.
Push-out fuse
Push-out fuses siv cov roj boron los txwv cov txheej txheem arcing. Lawv siv nyob rau hauv high voltage ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv 10 kV transformers.
Thaum lub fuse melts, cov roj boron extinguishes lub arc thiab raug tshem tawm los ntawm lub qhov nyob rau hauv lub raj.
Disable lub fuse
Drop-out fuses yog ib hom kev rub tawm fuses qhov twg qhov txuas fuse yog sib cais los ntawm lub cev fuse. Cov fuses no muaj ob qhov tseem ceeb; vaj tsev cutout thiab fuse tuav.
Lub fuse tuav lub tsev muaj qhov txuas fusible, thiab lub cev txiav tawm yog cov porcelain thav duab uas txhawb nqa lub fuse tuav los ntawm kev sib cuag sab saum toj thiab hauv qab.
Lub fuse tuav kuj tseem tuav ntawm lub kaum sab xis rau lub cutout lub cev thiab qhov no yog ua tiav vim li cas.
Thaum lub fuse txuas melts vim overcurrent los yog luv luv Circuit Court, lub fuse tuav yog disconnected los ntawm lub cev ntawm lub cutout nyob rau sab saum toj hu. Qhov no ua rau nws poob rau hauv lub ntiajteb txawj nqus, li no lub npe "poob fuse".
Tus tuav fuse poob kuj yog ib qho kev pom pom tias lub fuse tau tawg thiab yuav tsum tau hloov. Hom fuse no feem ntau yog siv los tiv thaiv qis voltage transformers.
Thermal fuse
Lub thermal fuse siv cov cim kub thiab cov ntsiab lus los tiv thaiv overcurrent lossis luv luv Circuit Court. Hom fuse no, tseem hu ua thermal cutout thiab dav siv nyob rau hauv cov khoom siv kub kub, siv cov rhiab alloy raws li qhov txuas fuse.
Thaum qhov kub nce mus txog qhov txawv txav, qhov txuas fusible melts thiab txiav tawm lub zog mus rau lwm qhov ntawm qhov ntsuas. Qhov no feem ntau yog ua los tiv thaiv hluav taws.
Resettable fuse
Resettable fuses tseem hu ua qhov zoo kub coefficient (PPTC) polymer fuses, los yog "polyfuses" luv luv, thiab muaj cov yam ntxwv uas ua rau lawv rov qab siv tau.
Hom fuse no muaj cov uas tsis yog-conductive crystalline polymer tov nrog conductive carbon hais. Lawv ua haujlwm nrog qhov kub thiab txias rau overcurrent lossis luv Circuit Court tiv thaiv.
Thaum txias, lub fuse tseem nyob rau hauv lub xeev crystalline, uas ua rau cov pa roj carbon nyob ze ua ke thiab tso cai rau lub zog dhau mus.
Nyob rau hauv cov ntaub ntawv ntawm cov khoom tam sim no ntau dhau, lub fuse heats li, hloov los ntawm crystalline daim ntawv mus rau ib tug tsawg compact amorphous xeev.
Cov pa roj carbon monoxide tam sim no sib nrug deb, uas txwv tsis pub muaj hluav taws xob txaus. Lub zog tseem ntws los ntawm qhov fuse thaum ua haujlwm, tab sis feem ntau yog ntsuas hauv milliamp ntau.
Thaum lub Circuit Court cools down, lub compact crystal lub xeev ntawm lub fuse yog rov qab thiab lub hwj chim ntws unhindered.
Los ntawm qhov no koj tuaj yeem pom tias Polyfuses tau rov pib dua, yog li lub npe "resettable fuses".
Lawv feem ntau pom muaj nyob rau hauv cov khoom siv hluav taws xob hauv computer thiab xov tooj, nrog rau hauv cov tshuab hluav taws xob, cov tshuab cua mus ncig, thiab lwm cov tshuab uas hloov cov khoom yuav ua pov thawj nyuaj heev.
semiconductor fuse
Semiconductor fuses yog ultra ceev fuses. Koj siv lawv los tiv thaiv cov khoom siv hluav taws xob hauv ib lub voj voog, xws li diodes thiab thyristors, vim tias lawv nkag siab rau qhov me me tam sim no.
