Fuse, peb hu rau fuse hauv lub neej txhua hnub, nws yog siv los tiv thaiv Circuit Court los ntawm ntau dhau thiab luv Circuit Court. Thaum qhov tam sim no los ntawm kev fuse yog ntau dua li tus nqi teev tseg, cov yaj yuav yaj los ntawm nws cov cua sov kom tawg lub voj voog. Fuse tau muab faib rau cov hom phiaj dav dav thiab cov khoom siv hluav taws xob tiv thaiv kab hluav taws xob tiv thaiv fuse raws li nws lub hom phiaj.
(1) Qhov kev xaiv ntawm cov laj thawj dav tau muab faib ua:
1. Cov hlau hlau (kab) tiv thaiv
Tshaj dhau ntawm qhov hluav taws xob thiab luv luv tam sim no hauv Circuit Court yuav ua rau lub xaim thiab cable kub dhau mus, uas ua rau kev puas tsuaj rau lub rwb thaiv tsev ntawm xaim thiab cable, lossis txawm tawg. Tus neeg xyuas pib thiab cable dhau kev tiv thaiv tuaj yeem ua raws li tus neeg tam sim no muaj peev xwm ntawm tus neeg xyuas pib, cable, txheej txheej txheej, hom, rwb thaiv tsev cov khoom qib, thiab lwm yam. teem rau ntawm tus neeg xyuas pib, cable txuas rau hauv lossis qhov hluav taws xob, Lub fuse rau kev tiv thaiv luv luv Circuit Court yuav tsum tau muab nruab rau ntawm cov khoom kawg ntawm cov hlau.
2. Lub cev muaj zog tiv thaiv
Circuit Court hluav taws xob yooj yim feem ntau yog ua los ntawm fuse-contactor-thermal relay-motor. Raws li kev paub dhau los, hauv Circuit Court, qhov ntsuas tam sim no ntawm lub fuse yog li ntawm 1.2 ~ 1.5 npaug ntawm qhov ntsuas tam sim no ntawm lub cev muaj zog.
3. Mining kab luv luv Circuit Court thiab tshaj kev tiv thaiv
Lub fuse ua raws li cov kev cai rau cov cuab yeej hluav taws xob tsuas thiab tuaj yeem siv rau kev ua haujlwm thiab cov thaiv kev ua txhaum.
4. Capacitor hloov khoom siv tiv thaiv
Hauv cov khoom siv hloov pauv ntawm lub ntsuas hluav taws xob, lub fuse raug pom zoo rau kev tiv thaiv luv luv, thiab qhov tam sim no ntawm qhov xaiv fuse yuav tsum tsis pub tsawg dua 1.6 npaug ntawm qhov ntsuas tam sim no ntawm lub capacitor.
(2) Kev xaiv ntawm fuse rau semiconductor cov cuab yeej tiv thaiv
Thaum lub tshuab hluav taws xob ua haujlwm, qhov txhaum tam sim no tshwm sim los ntawm qhov kev ua txhaum sab hauv lossis sab nraud ntawm cov khoom siv semiconductor. Vim li no, lub fuse yuav tsum tau siv kom nrawm txiav qhov txhaum tam sim no. Qhov kev xaiv kom raug ntawm cov fuses tuaj yeem tiv thaiv cov khoom siv semiconductor thiab hloov. Cov ntsiab cai dav dav ntawm kev xaiv fuse yog raws li hauv qab no:
1. Rated voltage
Cov ntsuas hluav taws xob ntawm lub fuse yog txiav txim siab los ntawm kev ua hauj lwm voltage ntawm lub teeb tsa, thiab nws yuav tsum muaj ntau dua los yog sib npaug nrog qhov ua hauj lwm voltage.
Yog hais tias qhov ua hauj lwm voltage ntawm Circuit Court tshaj qhov ntsuas hluav taws xob ntawm lub fuse, ob lub fuses tuaj yeem siv hauv cov ntawv. Lub sijhawm no, nws yuav tsum ua kom ntseeg tau tias lub luv-Circuit Court tam sim no ntawm qhov chaw nruab teeb tsa tsawg kawg 10 zaug ntawm qhov ntsuas rau tam sim no.
2. Rated tam sim no
Cov ntsuas tam sim no ntawm lub fuse yog txiav txim siab los ntawm cov txiaj ntsig zoo ntawm tus nqi tam sim no ntawm qhov chaw teeb tsa. Cov txiaj ntsig zoo ntawm qhov tam sim no ntawm kev teeb tsa teeb tsa nyob ntawm cov kab sib txawv ntawm cov hloov khoom siv. Yog tias qib tam sim no ntawm lub fuse tsis tuaj yeem ua tau raws li txoj kab, ob fuses ntawm tib qho kev qhia tshwj xeeb tuaj yeem siv ua ke, thiab kev faib tawm tsis sib xws ntawm fuse tam sim no thaum siv nyob rau hauv parallel yog li parallel 5%.
3. Txuas nruab nrab overvoltage
Thaum lub sijhawm arc txo cov txheej txheem ntawm qhov fuse, ib qho overvoltage tsim nyob rau hauv Circuit Court. Ntau dhau overvoltage yuav ua rau thim rov qab ntawm cov khoom siv semiconductor. Vim li no, lub fuse qhib overvoltage tuaj yeem pom raws li daim qauv piv txwv. Lub disconection overvoltage yuav tsum muaj tsawg dua los yog sib luag mus rau sab nraud qhov ntsuas hluav taws xob tso cai los ntawm cov khoom siv thev taws xob.
4. Rated rhuav lub peev xwm
Qhov ntsuas kub txaus ua tiav ntawm qhov fuse yuav tsum loj tshaj qhov luv luv-luv luv tam sim no uas yuav tshwm sim hauv kab.
5. Cov qauv tiv thaiv
Lub sijhawm tam sim no tus yam ntxwv ntawm fuse tuaj yeem pom los ntawm tus qauv piv txwv lub sijhawm tam sim no tus yam ntxwv nkhaus. Tshaj cov cuab yeej tiv thaiv ntawm lub twj tso tawm hluav taws xob tuaj yeem tiv thaiv los ntawm lwm cov khoom siv hloov mus, xws li DC hloov ceev.
Txawm li cas los xij, hauv kev ua haujlwm tiag tiag, peb feem ntau ntsib ntau yam kev rho tawm fuse pawg (raug xa mus ua riam-fuse keyboards), uas yuav tsum tau teeb tsa nrog cov fuses. Cov fuses no feem ntau muab faib ua hom, suav nrog cov riam-puab, cylindrical, thiab muab kauv. Cov duab ntawm rab riam tau muab faib ua cov ntsiab lus tshwj xeeb xws li 00C (000), 00, 0, 1, 2, 3, thiab 4 los ntawm qhov pom ntawm qhov loj me. Ntawm cov fuses no, feem ntau ntawm cov fuses tau teeb tsa nrog kev cais tawm fuse pab pawg yog cov hniav fuses. Hauv cov txheej txheem kev teeb tsa, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov loj me thiab cov ntsiab lus teeb tsa ntawm cov pab pawg sib cais fuse pawg, xws li ABB' s kev rho tawm fuse pab pawg OS-160, rab riam zoo li tus fuse tau teeb tsa yog. 00 fuse tub ntxhais. Tam sim no, cov fuse nquag siv hauv kev muag khoom suav nrog ob hom Dissmann thiab Bussmann.
