Nyob rau hauv kev lag luam kub tswj, hluav taws xob cua sov, thiab lub cev muaj zog ceev tswj kev siv, lub hwj chim regulators (xws li SCR (Silicon Controlled Rectifier) modules) ua hauj lwm raws li ib tug tseem ceeb lub hwj chim tswj units, thiab lawv cov hauj lwm ruaj khov ncaj qha cuam tshuam qhov kev ntseeg ntawm tag nrho cov system. Txawm li cas los xij, nquag fuse blowouts nyob rau hauv cov khoom siv feem ntau qhia tias txawv txav overcurrent lossis muaj peev xwm ua txhaum hauv Circuit Court. Kev nkag siab zoo txog cov laj thawj thiab kev siv cov kev daws teeb meem hauv lub cev yog qhov tseem ceeb rau kev ua kom lub sijhawm ntev -kev nyab xeeb ntawm cov khoom siv.
Ua ntej, kev thauj khoom txawv txav yog qhov tshwm sim ntau tshaj plaws. Thaum ib qho luv luv Circuit Court tshwm sim nyob rau hauv lub cua sov, induction kauj, los yog lub cev muaj zog winding, tam sim no muaj peev xwm surge instantaneously mus rau ob peb lub sij hawm nws rated nqi, deb tshaj lub fuse lub peev xwm thiab ua rau nws tshuab sai heev. Tsis tas li ntawd, yog tias qhov tseeb ntawm lub zog thauj khoom tsis tu ncua dhau ntawm qhov ntsuas hluav taws xob tsim qauv txwv, nws tuaj yeem ua rau lub sijhawm ntev overcurrent, ua rau lub fuse hlawv tawm vim muaj cua sov. Nyob rau hauv cov xwm txheej zoo li no, cov khoom siv tooj liab kawg feem ntau siv ntawm ob qhov kawg ntawm lub fuse kom paub meej kev sib cuag zoo; Txawm li cas los xij, yog tias lub load nws tus kheej tsis zoo, txawm tias lub kaus mom kawg zoo tshaj plaws tsis tuaj yeem tiv thaiv melting.
Thib ob, cov khoom siv sab hauv tsis ua haujlwm hauv lub zog tswj hwm yog lwm qhov laj thawj tseem ceeb. Kev tawg thiab luv Circuit Court nyob rau hauv silicon tswj rectifier (SCR los yog TRIAC) yog tshwj xeeb tshaj yog ib yam -ib zaug puas lawm, nws yog sib npaug rau ncaj qha mus txuas rau lub input thiab tso zis, poob nws voltage regulation muaj nuj nqi, thiab tsim ib tug nyob ze - luv Circuit Court. Nyob rau tib lub sijhawm, kev laus thiab tsis ua haujlwm ntawm lub voj voog tsav, synchronous transformer, lossis lim capacitor kuj tuaj yeem ua rau tsis zoo conduction lossis oscillation, tsim ntau dhau tam sim no. Nws yog ib qho tsim nyog sau cia tias ntau qhov kev lag luam - qib fuses siv lub Copper Cap rau European Cylindrical Fuse Link tsim. Lawv lub kaus mom tooj liab tsis tsuas yog muaj kev ua tau zoo heev tab sis kuj tseem muaj kev ruaj ntseg ntawm qhov kub thiab txias, thaum tseem muab kev tiv thaiv sai tiv thaiv cov kab hluav taws xob sab hauv.
Thib peb, kev xaiv fuse tsis raug feem ntau raug saib xyuas. Qee cov neeg siv xaiv nrawm- tshuab fuses nkaus xwb raws li qhov ntsuas tam sim no, tsis xav txog qhov cuam tshuam tam sim no thaum lub sijhawm pib thauj khoom (piv txwv li, qhov tsis txias txias-lub xeev tsis kam ntawm cov cua sov tso cai rau qhov pib tam sim no mus txog 3-5 npaug ntawm qhov ruaj khov- xeev tam sim no). Hauv cov xwm txheej zoo li no, yuav tsum siv lub tshuab fuse qeeb qeeb, feem ntau muaj lub fuse tooj liab thiab cov khoom siv tshwj xeeb alloy fusible, muaj peev xwm tiv taus luv luv surges yam tsis muaj tripping. Kev siv lub tshuab hluav taws xob nrawm tuaj yeem ua rau nws tshuab txhua zaus, txawm tias lub kaw lus ua haujlwm li qub.
Tsis tas li ntawd, qhov chaw nyob sab nraud ntawm daim phiaj hluav taws xob thiab cov teeb meem thaiv tsis tuaj yeem raug ignored. Sudden voltage spikes (xws li los ntawm xob laim ntaus lossis pib / nres ntawm siab- cov khoom siv hluav taws xob) tuaj yeem ua rau lub sijhawm dhau ntawm qhov kev tawm tswv yim, ua rau muaj kev kub ntxhov tam sim no. Nyob rau tib lub sijhawm, thim rov qab lub zog thiab thauj khoom sib txuas, tsis zoo hauv av, lossis kev laus thiab cov rwb thaiv tsev puas tuaj yeem ua rau xau lossis txawm tias theem - mus rau -theem luv circuits. Nyob rau hauv siab -voltage DC lossis AC systems, tooj liab hlau kawg caps feem ntau yog siv ntawm lub fuse terminals los txhim kho kev sib txuas kev ntseeg tau. Txawm li cas los xij, yog tias lub installation yog xoob lossis oxidized, nws tuaj yeem ua rau cov cua sov hauv zos thiab ua rau muaj kev sib tsoo.
Txhawm rau daws cov teeb meem saum toj no, cov txheej txheem daws teeb meem raug pom zoo.
Ua ntej, ntsuas qhov load tom qab fais fab tuag: Siv lub megohmmeter los ntsuas cov rwb thaiv tsev tiv thaiv hauv av thiab multimeter los ntsuas qhov txias -lub xeev tsis kam los txiav txim siab seb puas muaj hluav taws xob luv luv lossis tsis zoo sib xws.
Thib ob, sim SCR: Siv lub tshuab hluav taws xob digital hauv hom diode los ntsuas A-K thiab G-K inter- cov yam ntxwv ntawm electrode. Yog tias nws ua nyob rau hauv ob qho tib si rau pem hauv ntej thiab rov qab cov lus qhia (ze rau 0Ω), nws luv luv -circuited.
Thib peb, pom lub ntsej muag tshuaj xyuas lub rooj tsav xwm hauv Circuit Court: kuaj xyuas qhov kub hnyiab, bulging capacitors, tawg pob qij txha, lossis lwm yam kev puas tsuaj.
Plaub, ntsuas cov cua kub dissipation tej yam kev mob: ntxuav cov plua plav tawm ntawm lub heatsink thiab xyuas kom cov kiv cua ua hauj lwm ib txwm los tiv thaiv cov khoom parameter drift vim kub ntau dhau.
Thib tsib, txheeb xyuas cov fuse specifications: Paub meej tias nws qhov ntsuas hluav taws xob, tam sim no, tawg muaj peev xwm, thiab lub sijhawm- cov yam ntxwv tam sim no phim cov kev ua haujlwm tiag tiag.
Thaum kawg, xyuas kom meej cov xaim: xyuas kom tag nrho cov terminals muaj kev ruaj ntseg, cov theem sib lawv liag yog lawm, thiab tsis muaj cov conductors raug.
Nyob rau hauv siab - zoo fuse manufacturing, precision tooj liab caps xws li Custom Copper Caps thiab Copper Pipe End Caps yog dav siv los txhim kho hluav taws xob thiab kev ua haujlwm zoo. Cov khoom no yog tsim los ntawm high-purity tooj liab los ntawm stamping, ua rau ib tug du nto thiab siab conductivity, zoo txo kev tiv thaiv thiab txo qhov kev pheej hmoo ntawm overheating. Txawm li cas los xij, txawm tias muaj cov khoom zoo siab - zoo li Copper End Caps, yog tias lub hauv paus tsis ua haujlwm tshwm sim, lub fuse tseem yuav ua tiav nws lub luag haujlwm raws li "kab kawg ntawm kev tiv thaiv."
Hauv kev xaus, nquag fuse tshuab tsis yog ib qho tshwm sim cais, tab sis yog ib qho kev tshwm sim sab nraud ntawm qhov system malfunction. Tsuas yog los ntawm kev hais txog qhov teeb meem los ntawm ntau qhov ntev, suav nrog kev thauj khoom, cov khoom siv, kev xaiv, thiab ib puag ncig, tuaj yeem ua lub hauv paus ua kom raug thiab nyob ntev - lub sijhawm ua haujlwm ruaj khov.
Yog tias koj ntsib teeb meem daws teeb meem hauv lub tshuab hluav taws xob hauv koj lub tshuab hluav taws xob, lossis xav tau cov lus qhia sib haum rau cov khoom xws liCopper Caps, thov hu rau peb. Peb pab neeg tshaj lij yuav muab kev txhawb nqa thiab kev daws teeb meem rau koj.
