fuses siv nyob txhua qhov chaw thiab txhua qhov chaw - lawv nyob hauv kev siv tshuab, hauv ntau yam khoom siv hluav taws xob, tsheb, khoom siv hauv tsev. Muaj ntau hom ntawm cov ntsiab lus no. Dab tsi yog lawv rau thiab dab tsi yog lawv cov nta? Xav txog yam tseem ceeb ntawm fuses.

yam ntxwv

Fuse yog ib lub ntsiab lus uas siv ncaj qha rau hauv hluav taws xob. Qhov no muab kev tiv thaiv rau cov xov hlau, khoom siv thiab hluav taws xob tes hauj lwm.

Lub fuse yog cov khoom siv hloov pauv. Nws lub hom phiaj yog dab tsi? Lub fuse yog tsim los tiv thaiv hluav taws xob network los ntawm cov hluav taws xob siab thiab luv luv. Lub hauv paus ntsiab lus ntawm kev khiav hauj lwm ntawm ib feem yog yooj yim heev - nyob rau hauv cov kev tshwm sim ntawm lub tsim ntawm overcurrents, lub ntsiab tshwj xeeb uas tsim los rau qhov no yog puas. Feem ntau qhov no yog qhov txuas fusible. Nov yog yuav ua li cas txhua hom iav fuses tau npaj.

Cov ntaub ntawv no yog ib qho tseem ceeb ntawm cov khoom, yam tsis muaj hom kev nyab xeeb ua tau. Nyob rau hauv nws kuj muaj ib tug tshwj xeeb arc-extinguishing ntaus ntawv. Ntxig rau hauvfuses yog ua los ntawm cov plooj (porcelain) lossis fiber ntau thiab raug kho rau hauv qhov tshwj xeeb uas ua rau hluav taws xob. Cov ntsiab lus tsim los rau cov dej ntws qis yuav tsis muaj qhov xwm txheej txhua.

Fusible

Cov no yog hom fuses ntau tshaj plaws rau kev siv hauv tsev. Qhov no tej zaum tsuas yog lub ntsiab lus uas yooj yim tshaj rau kev kuaj mob rau kev pabcuam. Txhawm rau ua qhov no, koj tsuas yog yuav tsum tau saib ntawm qhov chaw nyob hauv lub teeb - nws yuav pom tseeb tias qhov melting ntawm qhov ntxig yog puas lawm.

Cov khoom no yog ua rau hauv lub khob iav.

Fusible Tubular Ceramic

Cov khoom no yog xyaum tsis txawv ntawm cov khoom iav. Qhov txawv tsuas yog nyob rau hauv cov ntaub ntawv uas yog ua los ntawm. Tab sis hauv kev ua haujlwm, cov khoom no tsis xis nyob - nws yuav tsis tuaj yeem kuaj xyuas "ntawm lub teeb". Txhawm rau kuaj xyuas, koj yuav tsum siv cov ntsuas ntsuas lossis ntsuas ntsuas.

PVD fusible link

Cov hom fuses no ua haujlwm ntawm tib lub hauv paus ntsiab lus.

Tab sis ntawm no tus qauv tsim tau hloov kho raws li pom lub xeev ntawm ntu. Yog li, yog tias cov khoom raug hlawv tawm, ces tus chij tshwj xeeb yuav tshwm sim tom qab ntawm cov khoom.

Quartz Sand Elements

Cov fuses no muaj cov yam ntxwv siab arc-extinguishing. Lawv yog tsim nyob rau hauv ob versions: nyob rau hauv ib rooj plaub ua los ntawm ceramics los yog iav rooj. Feem ntau cov khoom tsim los ua haujlwm nrog cov dej ntws siab. Muaj ntautxhim kho cov qauv. Cov khoom siv fuse muab rau ib qho kev nthuav dav ntxiv, zoo ib yam hauv kev tsim rau LDPE. Nws yog ib qho tsim nyog kom koj thiaj li paub tias lub fuse tau tawg.

fast acting fuses

Cov khoom no tsis muaj dab tsi tshwj xeeb los ntawm tus so. Qhov txawv tsuas yog thaum lub caij luv luv tshwm sim, qhov fusible burns tawm sai heev.

SMD

Cov khoom no tuaj yeem pom hauv cov khoom siv hluav taws xob. Lawv me me heev. Lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab lub hom phiaj ntawm fuses yog los tiv thaiv cov cuab yeej los ntawm cov dej ntws siab, uas lawv ua tau zoo heev.

Kev kho tus kheej

Cov no yog cov kev daws teeb meem zoo heev. Ib tug self-reetting fuse yog ib feem nrog ib tug tshwj xeeb yas nyob rau hauv. Tsuav cov yas ntxig yog txias, nws tuaj yeem ua hluav taws xob. Sai li qhov ntxig ntxig rau qhov kub thiab txias, nws cov khoom siv hluav taws xob poob vim qhov nce hauv qhov tsis kam.

Tom qab txias, tam sim no rov tuaj yeem dhau los ntawm cov khoom. Qhov zoo ntawm cov khoom no yog tias tom qab burnout tsis tas yuav hloov lub caij. Kev lag luam tsim cov khoom no hauv ntau hom. Lawv tsim nyog rau nto mount lossis nto mount soldering. Yeej, cov fuses no yog siv nyob rau hauv cov hluav taws xob qis.

Explosive

Yog tias txhua tus paub txhua yam ntawm cov khoom saum toj no, ces cov fuse tawg yog ib pawg tsawg. Cov txheej txheem ntawm burnout ntawm ib feem yog muab los ntawm ib tug zoo duasuab. Ib qho khoom tawg tshwj xeeb, uas txuas nrog rau cov khoom siv hluav taws xob, tawg. Cov sensors tshwj xeeb yog lub luag haujlwm rau qhov no. Lub tom kawg saib xyuas qhov tam sim no hauv hluav taws xob Circuit Court. Cov no yog cov fuses raug heev, vim tias lawv tsis muaj kev ywj pheej ntawm cov yam ntxwv ntawm cov hlau ntawm cov khoom siv hluav taws xob. Cov khoom no nyob ntawm qhov raug ntawm qhov ntsuas tam sim no.

Lwm hom fuses

Ua haujlwm hauv cov hluav taws xob hluav taws xob siab, tshwj xeeb autogas, cov khoom siv roj, nrog rau cov khoom siv ua kua. Tseem muaj firing fuses. Koj tsis tuaj yeem pom lawv hauv lub neej niaj hnub - qhov no yog cov cuab yeej muaj zog tshaj lij.

Txhua qhov chaw tsim khoom tsim cov fuses raws li tus lej tshwj xeeb lossis tus lej. Tus lej fuse tso cai rau koj los nrhiav thiab qhia meej cov kev qhia tshwj xeeb hauv cov ntawv teev npe. Feem ntau cov lej no tuaj yeem pom ntawm rooj plaub ntawm cov khoom. Tsis tas li ntawd, cov cai tuaj yeem siv rau ntawm cov hlau. Ntxiv rau cov lej, cov ntaub ntawv yooj yim kuj tuaj yeem qhia rau ntawm rooj plaub - qhov no yog qhov ntsuas tam sim no hauv A, ntsuas qhov ntsuas hluav taws xob hauv V, cov yam ntxwv tsis zoo lossis cov qauv tsim. Los ntawm cov ntaub ntawv no, lub hom phiaj ntawm fuses tuaj yeem txiav txim siab.

Yog li, tus nqi ntawm qhov ntsuas tam sim no yog qhov siab tshaj plaws tso cai tus nqi ntawm qhov chaw tuaj yeem ua haujlwm ib txwm siv sijhawm ntev.

Rated voltages yog qhov siab tshaj plaws qhov hluav taws xob tso cai ntawm qhov chaw yuav ua rau muaj kev nyab xeeb ntawm lub voj voog thaum muaj kev sib tw luv luv lossis lub network overload.

Lub peev xwm tawg yog hu ua qhov siab tshaj plaws tam sim no. Nrog lawv, lub fuse yuav ua haujlwm, tab sis nws cov ntaub ntawv yuav tsis raug puas tsuaj.

yam ntxwv yog qhov kev vam khom ntawm lub sijhawm uas lub ntsiab lus fusible vau rau ntawm qhov tam sim no uas ntws los ntawm ib feem. Ntau hom fuses raws li lawv cov yam ntxwv tau muab tso ua ke rau hauv pawg raws li cov yam ntxwv ntawm daim ntawv thov thiab cov lus teb ceev.

Feem ntau cov yam ntxwv no tau qhia rau ntawm lub zog. Cov tsiaj ntawv ntawm cov tsiaj ntawv Latin yog siv rau kev xaiv. Thawj yog lub peev xwm tawg. Yog li, G yog tag nrho ntau yam, ib feem muaj peev xwm tiv thaiv Circuit Court ntawm ob qho tib si overload thiab luv luv Circuit Court. A - qhov ntau yog ib feem, thiab cov fuses no tsuas yog tiv thaiv luv luv xwb.

Tsab ntawv thib ob qhia txog cov saw hlau:

  • G is a general purpose circuit.
  • L - tiv thaiv cov cables nrog rau kev faib khoom.
  • M - tiv thaiv circuits hauv hluav taws xob motors.
  • Tr yog lub fuse uas tuaj yeem tiv thaiv lub network transformer.

Cov ntsiab lus nrog tsab ntawv R yog siv ua ke nrog cov khoom siv hluav taws xob semiconductor. Thiab PV yuav tuaj yeem tiv thaiv hnub ci vaj huam sib luag.

Yog li, peb tau saib seb hom fuses yog dab tsi thiab cov cim lawv muaj dab tsi.
