Lub hom phiaj tseem ceeb
Lub fuse yog tsim rau kab overload thiab luv-circuit tiv thaiv nyob rau hauv cov khoom faib khoom ntawm cov khoom siv hluav taws xob nrog AC ntsuas zaus ntawm 50Hz, ntsuas qhov hluav taws xob ntawm AC rau 690V, DC 250V txog 440V thiab ntsuas cunent rau 1250A.
1.2 Hom thiab specification
Hom thiab specification
Fuse muab faib ua rau qhov ntau thiab tsawg raws li qhov loj ntawm fuse raj.Txhua qhov loj muaj conesponding rated tam sim no ntau yam.Xa mus rau lub ntsiab technical parameters rau rated cun ent theem ntawm fuse ntawm ntau qhov ntau thiab tsawg.Lub fuse tuaj yeem nruab nrog tus impactor raws li tus neeg siv yuav tsum tau ua, thiab cov impactor feem ntau nyob ncaj qha saum lub fuse tiv tauj.
Nomenclature ntawm fuses
Ib txwm ua haujlwm
◆ Ambient huab cua kub
Qhov kub ntawm huab cua puag ncig yuav tsum tsis pub tshaj 40 ° C, qhov nruab nrab tus nqi ntsuas hauv 24 teev yuav tsum tsis pub tshaj 35 ° C, thiab qhov nruab nrab tus nqi ntsuas hauv ib xyoos yuav tsum qis dua tus nqi no.
Qhov tsawg kawg nkaus ambient kub yog - 5 C.
◆ Qhov siab
Qhov siab ntawm qhov chaw teeb tsa yuav tsum tsis pub tshaj 2000m.
◆ Huab cua tej yam kev mob
Nws tus txheeb ze av noo yuav tsum tsis pub tshaj 50% ntawm qhov kub siab tshaj ntawm 40 ° C
Cov av noo siab dua tuaj yeem tau txais ntawm qhov kub qis dua, piv txwv li, txog li 90% ntawm 20C.
Nyob rau hauv cov xwm txheej no, qhov nruab nrab condensation tuaj yeem tshwm sim los ntawm lub sijhawm vim qhov kub thiab txias hloov.Yog tias tsis muaj kev sib tham nrog cov chaw tsim khoom, lub fuse tsis tuaj yeem ntsia tau rau hauv qhov chaw nrog ntsev pos huab lossis txawv txav kev lag luam tso nyiaj.
◆ Voltage
Qhov siab tshaj qhov system voltage yuav tsum tsis pub tshaj 1 10% ntawm qhov ntsuas fuse voltage.
Rau fuse nrog cov ntsuas hluav taws xob ntawm 690V AC thiab 250V 1440V DC, qhov siab tshaj plaws qhov hluav taws xob yuav tsum tsis pub tshaj 105% ntawm cov ntsuas hluav taws xob ntawm fuse.
Tej yam kev mob ntawm installation
◆ Kev teeb tsa qeb
Pawg installation ntawm fuse yog chav kawm I.
◆ Cov pa phem
Kev tiv thaiv kev ua qias tuaj ntawm fuse yuav tsum tsis txhob qis dua qib 3.
◆ Kev teeb tsa hom
Lub fuse tuaj yeem ntsia tau ntsug, kab rov tav lossis obliquely hauv qhov chaw ua haujlwm yam tsis muaj kev co tseem ceeb thiab cuam tshuam kev co.
Breaking ntau thiab siv qeb
Lub fuse txuas rau fuse yog fuse txuas nrog lub hom phiaj dav dav thiab muaj peev xwm tawg tag nrho, piv txwv li "gG" fuse txuas.
Cov yam ntxwv ntawm cov qauv thiab cov qauv kev ua haujlwm
Lub fuse muaj fuse puag thiab fuse txuas.Lub hauv paus fuse yog tsim los ntawm lub hauv paus kev sib cuag, lub hauv paus phaj, thiab lwm yam. Lub fuse txuas yog tsim los ntawm fuse raj, yaj, quartz xuab zeb, riam hom kev sib cuag, thiab lwm yam.
Thaum lub fuse raug ntsia rau hauv Circuit Court, thaum tam sim no dhau los ntawm lub fuse dhau ib qho nqi rau lub sijhawm txaus, cov yaj hauv lub cev fuse yuav raug fused, thiab cov arc generated thaum lub fuse yog fused los ntawm quartz xuab zeb nyob rau hauv lub fuse. raj yuav raug extinguished, thiaj li mus cuag lub hom phiaj ntawm breaking Circuit Court.
Thaum cov yaj tau tawg, qhov taw qhia ntawm qhov txuas fuse yuav tshwm sim, qhia tias qhov txuas fuse tau tawg.
Rau lub fuse nruab nrog ib tug impactor, thaum lub yaj yog fused, lub impactor yuav pop tawm tuaj.Tus neeg siv tsuas yog yuav tsum tau nruab ib lub micro-switch lossis lub teeb liab tsim nyog xa khoom (xaiv thiab yuav los ntawm tus neeg siv) nyob rau hauv pem hauv ntej ntawm lub impactor, thiab tom qab ntawd cov teeb liab yuav tsum tau muab tom qab lub fuse yog fused.

Thaum lub fuse txuas tau tawg, lub fuse txuas tshiab nrog tib tus qauv, qhov loj me thiab ntsuas tam sim no raws li tus thawj fuse txuas yuav tsum tau hloov pauv tsis siv tooj liab.
Kev hloov cov fuse txuas yuav tsum tau ua los ntawm cov kws tshaj lij uas siv cov fuse tshwj xeeb.
Thaum hloov qhov txuas fuse, nws yuav tsum tau nqa tawm nyob rau hauv qhov xwm txheej tsis muaj kev thauj khoom, zoo dua thaum lub zog hluav taws xob raug txiav tawm.Nws yog kiag li tsis tso cai rau siv lub fuse txiav tawm los yog txuas lub load thaum hloov mus siv.Tom qab hloov lub fuse txuas, xyuas kom meej tias kev sib cuag ntawm lub fuse txuas thiab lub hauv paus kev sib cuag yog nyob rau hauv kev sib cuag zoo.
Thaum hloov cov khoom siv hluav taws xob thiab hloov qhov txuas fuse, thov tshem tawm cov plua plav thiab lwm yam av ntawm lub hauv paus fuse, tshwj xeeb tshaj yog kev sib cuag ntawm lub hauv paus, kom lub fuse ua haujlwm zoo.
Thaum lub sijhawm ua haujlwm, qhov taw qhia ntawm fuse txuas yuav tsum tau tshuaj xyuas ntau zaus txhawm rau txhawm rau tshawb pom cov haujlwm ib-theem lossis ploj lawm hauv lub sijhawm.
Kev thauj mus los thiab khaws cia ntawm fuse
Lub fuse yuav tsum tau tiv thaiv los ntawm nag thiab daus thaum thauj thiab khaws cia.Qhov siab poob siab ntawm tag nrho lub thawv fuse yuav tsum tsis txhob siab tshaj 250mm.
Fuses yuav tsum tau muab cia rau hauv qhov chaw uas muaj huab cua ncig thiab ib puag ncig qhuav, thiab qhov siab stacking yuav tsum tsis pub tshaj rau txheej.
Unpacking thiab tshuaj xyuas ntawm fuse
Tom qab unpacking, ua ntej xyuas seb daim ntawv teev npe ntawm lub fuse puas zoo ib yam nrog cov ntawv ntim thiab cov cim ntawm lub thawv ntim khoom, tom qab ntawd xyuas seb lub fastener ntawm lub hauv paus fuse los yog fuse txuas yog xoob los yog poob o 比 kos seb lub porcelain raj ntawm lub fuse yog li cas. fuse txuas yog tawg lossis tawg, xyuas seb cov xuab zeb quartz hauv lub fuse thaiv puas tawm, thiab xyuas seb lub fuse puas tau ntub los yog tawm tsam los ntawm dej.Yog tias pom cov xwm txheej saum toj no, lub fuse tsis tuaj yeem siv tau, thiab cov chaw tsim khoom yuav tsum hu rau lub sijhawm.
Lub thawv fuse yuav tsum muaj daim ntawv pov thawj khoom, cov npe ntim khoom thiab cov lus qhia ua haujlwm.
Ordering cov lus qhia
Thaum xaj fuses, tus qauv, specification, kom muaj nuj nqis thiab qib tam sim no ntawm cov fuse txuas yuav tsum tau qhia.Lub hauv paus fuse thiab fuse txuas tuaj yeem txiav txim cais.
Rau fuses ntawm tshwj xeeb specifications thiab theem tam sim no, cov chaw tsim tshuaj paus yuav tsum tau sab laj thaum txiav txim.
