Yuav ua li cas rau nruab thiab xaiv fuses kom raug? Ib Daim Ntawv Qhia Txog Kev Txhim Kho Cov Txheej Txheem, Cov Cai Xaiv, thiab Daim Ntawv Thov

Fuses yog ib qho tseem ceeb tshaj plaws tiv thaiv hluav taws xob tiv thaiv nyob rau hauv qis -voltage fais fab faib tshuab; lawv lub luag haujlwm tseem ceeb yog cuam tshuam qhov cuam tshuam sai sai thaum lub sijhawm luv luv -circuit lossis overload txheej xwm, yog li tiv thaiv cov khoom siv hluav taws xob thiab hluav taws xob. Txawm hais tias nyob rau hauv kev lag luam fais fab, lub zog tshiab, lossis cov khoom siv automation, kev xaiv kom zoo ntawm fuses thiab lawv cov fuse tuav ncaj qha cuam tshuam rau lub cev kev nyab xeeb, kev ruaj ntseg, thiab kev saib xyuas zoo. Yog li ntawd, mastering installation cov qauv thiab xaiv cov hauv paus ntsiab lus rau fuses yog qhov tseem ceeb rau hluav taws xob engineering tsim thiab kho cov cuab yeej siv.

Kev xaiv ntawm lub fuse yuav tsum muaj kev ntsuam xyuas dav dav ntawm qhov chaw ua haujlwm tiag tiag, ua haujlwm voltage, ntsuas tam sim no, thiab cov yam ntxwv thauj khoom, tsis yog tsuas yog tso siab rau tus nqi tam sim no. Rau cov ntawv thov xws li DC fais fab kev faib tawm, kev siv hluav taws xob tauj dua tshiab, thiab cov tsheb hluav taws xob, tshwj xeeb yuav tsum tau them nyiaj rau kev rhuav tshem lub peev xwm thiab kev ua haujlwm rwb thaiv tsev; siv lub DC fuse yas dhos tsim nyog yog qhov tseem ceeb los xyuas kom ntseeg tau tias muaj kev tiv thaiv hluav taws xob hauv high -voltage DC ib puag ncig.

Thaum xaiv ib lub fuse, qhov ntsuas tam sim no ntawm lub fuse caij yuav tsum tau txiav txim siab ua ntej, ua raws li kev xaiv ntawm lub cev fuse sib haum raws li lub ntsiab lus tshwj xeeb. Lub fuse txoj kev tiv thaiv nkhaus yuav tsum ua raws li cov yam ntxwv dhau ntawm cov khoom tiv thaiv, ua kom muaj kev ua haujlwm sai thaum muaj kev ua txhaum thaum tiv thaiv kev cuam tshuam tsis zoo los ntawm kev pib tam sim no. Rau cov khoom siv hluav taws xob muaj hluav taws xob, siab - cov cuab yeej muaj peev xwm, thiab lub zog hloov pauv / faib tshuab, cov khoom siv NH feem ntau yog xaiv; cov no muaj peev xwm tawg tau zoo thiab muaj zog txhua yam muaj zog, ua tau raws li kev tiv thaiv kev tiv thaiv hauv kev xav tau kev ua haujlwm.

Hauv ntau-theem hluav taws xob faib hluav taws xob, kev sib raug zoo xaiv kev tiv thaiv yuav tsum raug tsim los ntawm fuses ntawm ntau qib. Feem ntau, qhov ntsuas tam sim no ntawm cov khoom siv hluav taws xob sab saud yuav tsum yog ob mus rau peb npaug ntawm cov khoom hauv qab; qhov no ua kom ntseeg tau tias tsuas yog lub faulty ceg raug txiav thaum lub sijhawm ua txhaum, tsis muaj kev cuam tshuam kev ua haujlwm ntawm tag nrho cov kab ke. Tsis tas li ntawd, kev teeb tsa yuav tsum siv NH low-voltage switch-disconnector fuse base uas phim cov fuse specifications, kom ruaj ntseg mounting, txhim khu kev qha kev sib cuag, thiab yooj yim rau yav tom ntej hloov thiab txij nkawm.

Ua ntej txhim kho lub fuse, xyuas kom meej tias cov khoom ntsuas qhov ntsuas hluav taws xob, ntsuas qhov muaj peev xwm tawg, thiab lub hauv paus mounting raws li qhov yuav tsum tau ua. Lub fuse qhov ntsuas hluav taws xob yuav tsum sib npaug lossis tshaj qhov hluav taws xob ua haujlwm ntawm qhov hluav taws xob, thiab nws cov peev txheej tawg yuav tsum tshaj qhov siab tshaj qhov luv luv - Circuit Court tam sim no ntawm lub kaw lus. Tsis tas li ntawd, xyuas kom lub fuse txuas qhov ntsuas tam sim no tsis pub dhau lub mounting bracket txwv thiab siv NH raws- hom fuse puag los txhim kho kev sib txuas ruaj khov.

fuses feem ntau ntsia tau ntsug kom ntseeg tau tias muaj kev sib cuag zoo ntawm qhov txuas fuse thiab cov hniav sib txuas, thaum txo qhov cuam tshuam ntawm arcing ntawm ib puag ncig. Tsis txhob muaj kev puas tsuaj rau cov khoom siv-xws li khoov lossis cuam tshuam- rau lub fuse txuas thaum lub sijhawm teeb tsa, vim qhov no tuaj yeem hloov kho nws tus ntoo khaub lig- ntu ntu, ua rau ua haujlwm tsis zoo lossis lub tshuab ua ntej. Rau cov khoom siv uas yuav tsum tau saib xyuas tsis tu ncua, siv tus qauv NH- hom fuse puag txhim kho kev txhim kho thiab txo lub sijhawm tu.

Ambient kub yog lwm qhov tseem ceeb cuam tshuam rau lub fuse cov yam ntxwv tiv thaiv. Qhov zoo tshaj plaws, qhov kub thiab txias nyob ib ncig ntawm lub fuse yuav tsum phim cov khoom siv tiv thaiv kom tsis txhob muaj qhov sib txawv ntawm lub sijhawm tshuab los ntawm qhov sib txawv ntawm qhov kub thiab txias. Kev sib txuas ntawm theem txhim khu kev qha yog qhov tseem ceeb thaum lub sijhawm teeb tsa los tiv thaiv cov teeb meem xws li kev kub ntxhov hauv cheeb tsam lossis ib zaug -phasing vim kev sib cuag tsis zoo. Rau cov tshuab uas muaj luv luv - lub peev xwm ntawm lub voj voog, siv lub fuse nrog lub peev xwm tawg siab yog pom zoo los txhim kho kev ruaj ntseg ntxiv.

Kev xaiv cov hauv paus ntsiab lus rau qhov txuas fuse qhov ntsuas tam sim no txawv nyob ntawm seb hom thauj khoom. Rau cov loads resistive-xws li teeb pom kev zoo lossis hluav taws xob cua sov- ua haujlwm tam sim no ruaj khov, yog li qhov ntsuas fuse tuaj yeem raug xaiv kom siab dua me ntsis siab dua qhov ntsuas tam sim no. Hloov pauv, vim tias lub tshuab hluav taws xob muaj qhov pib siab, lub fuse feem ntau tsuas yog luv luv - tiv thaiv Circuit Court, thaum tiv thaiv overload yog tswj los ntawm thermal relay. Hauv kev tswj hwm kev lag luam, siv NH qis-voltage fuse puag txhawb kev teeb tsa tus qauv thiab ua kom ntev- lub sijhawm ua haujlwm kev ntseeg siab.
