Yuav ua li cas xaiv txoj cai fuse rau cov neeg siv khoom?
Lub fuse yog hluav taws xob tiv thaiv kev tiv thaiv cov khoom siv hluav taws xob. Nws feem ntau txuas nrog rau hauv cov kab hauv Circuit Court. Thaum lub txhaum tam sim no nce mus rau ib qho nqi, nws fuses thiab txiav tawm hauv Circuit Court kom tiv thaiv lwm cov khoom siv hauv Circuit Court. Qhov feem ntau siv hauv Circuit Court overcurrent tiv thaiv Cheebtsam yog lub fuse.
Txoj Kev / Kauj Ruam
Lub hauv paus ntsiab lus ntawm qhov fuse:
Thaum lub fuse yog energized, vim nws qhov kev tawm tsam, lub zog hluav taws xob tau hloov mus rau hauv tshav kub kom ua rau cov yaj ua kom sov. Nyob rau tib lub sijhawm, cov kub uas tsim los ntawm cov hluav taws xob tam sim no mus rau qhov chaw ib puag ncig los ntawm kev yaj thiab lub plhaub, thiab dissipates cua sov los ntawm convection thiab conduction. Thaum lub fuse dhau qhov tso cai ua haujlwm tam sim no, lub tshav kub dissipated thiab lub tshav kub tsim kom ncav cuag qhov sib npaug. Cov cua sov yuav tsis zeem rau hauv yaj thiab nce qhov kub ntawm cov yaj, yog li cov fuse yuav tsis ncav cuag nws cov taw tes thiab yaj. Thaum qhov tam sim no dhau ntawm lub fuse mus txog ib qho nqi, lub tshav kub hloov los ntawm lub zog hluav taws xob nce, thiab lub tshav kub dissipation ceev tsis tuaj yeem ceev ceev nrog cov cua kub ceev. Cov cua sov no yuav maj mam nthuav tawm hauv cov yaj thiab nce qhov kub ntawm cov yaj. Thaum kub txog qhov chaw npau taws ntawm lub fuse Thaum lub fuse pib yaj thiab txuas ntxiv nqus cov cua kub kom yaj ntxiv thiab ua kua, ces qhov kub ntawm lub fuse ntxiv nce mus rau qhov chaw vaporization los tsim arc. Lub arc yog cov pa roj tsis muaj paug. Lub zog ntawm cov arc muaj feem xyuam nrog qhov hluav taws xob ntawm qhov Circuit Court. Qhov siab dua arc yog, qhov sib txawv tseem ceeb nyob rau hauv qhov ntsuas hluav taws xob ntawm lub fuse yog qhov hluav taws xob Circuit Court uas lub fuse tuaj yeem tiv taus thaum lub fuse yog tshuab. Lub fuse tsis tuaj yeem siv nyob rau hauv Circuit Court siab dua nws cov ntsuas hluav taws xob, vim tias arc tsis yooj yim rau kev tua thaum lub Circuit Court hluav taws xob ntau dua qhov ntsuas hluav taws xob ntawm fuse. Tsis tas li ntawd, lub zog ntawm arc tseem muaj feem xyuam rau tam sim no hauv Circuit Court. Qhov ntau dua tam sim no, qhov muaj zog dua arc. Yog hais tias lub arc tsis tuaj yeem tua tawm nyob rau hauv lub sijhawm, tsis tsuas yog lub tshuab hluav taws xob tsis tuaj yeem txiav tawm, tab sis lwm cov khoom siv hauv Circuit Court kuj yuav raug hlawv, uas yuav ua rau muaj hluav taws thiab ua rau muaj kev sib tsoo. Kev kub siab-pov thawj fuse yog siv los nruab cov ntawv pov thawj tawg ntawm cov xuab zeb kom tua cov arc. Lub fuse yuav tsuas txiav tawm qhov tam sim no tom qab lub arc raug tua, thiaj li tiv thaiv lwm cov khoom siv.
Cov qauv ntawm cov fuse:
Feem ntau, ib qho fuse raug tsim ua peb ntu: ib qho yog melt feem, uas yog qhov tseem ceeb ntawm cov fuse, uas txiav tawm ntawm Circuit Court thaum nws tshuab. Tus nqi kuj yuav tsum yog me me li thiab ua tau zoo ib yam. Qhov tseem ceeb tshaj plaws yog tias cov fusing yam ntxwv yuav tsum zoo sib xws;
Qhov thib ob yog cov electrode feem, feem ntau yog ob tug. Nws yog ib qho tseem ceeb ntawm kev sib txuas ntawm cov yaj thiab cov Circuit Court. Nws yuav tsum muaj cov hluav taws xob zoo hluav taws xob zoo thiab yuav tsum tsis tsim cov cuab yeej sib txuam tiv taus;
Qhov peb yog qhov ntu nkhaus. Qhov yaj ntawm cov fuse yog feem ntau nqaim thiab muag muag. Kev ua haujlwm ntawm txoj kab nrig yog kho cov yaj thiab ua rau peb ntu txhav thiab yooj yim rau nruab thiab siv. Nws yuav tsum muaj lub zog zoo txhua yam, rwb thaiv tsev, thiab tiv taus tshav kub. Nws yog tshuaj tiv thaiv thiab nplaim taws, thiab yuav tsum tsis txhob tawg, deformed, hlawv lossis luv luv hauv lub sijhawm siv.
Kev xaiv fuse:
1. Daim ntawv pov thawj kev nyab xeeb: Tshawb xyuas cov ntawv pov thawj kev nyab xeeb ntawm cov fuse raws li daim ntawv pov thawj kev nyab xeeb xav tau los ntawm lub tshuab tag nrho, xws li UL cov lus lossis IEC tshwj xeeb. 2. Cov qauv tsim: txiav txim siab qhov loj me me raws qhov chaw hauv kev tsim qauv hauv Circuit Court, xws li ntev, taub, thiab seb puas muaj cov coj, thiab lwm yam. 3. Rated voltage: yuav tsum muaj ntau dua los yog sib npaug ntawm daim ntawv thov tseeb , feem ntau 24V, 32V, 63V, 125V, 250V, thiab lwm yam 4. Txhaum lub peev xwm: yuav tsum muaj ntau tshaj qhov siab tshaj qhov txhaum tam sim no hauv Circuit Court. 5. Rated tam sim no: Xa mus rau cov khoom hauv qab no: (1) Ua haujlwm tam sim no, qhov ntsuas tam sim no ntawm UL kev qhia tshwj xeeb fuse khiav ntawm 25 ℃ yog ≥ qub ua haujlwm tam sim no / 0.75; Qhov ntsuas tam sim no ntawm IEC qhov tshwj xeeb fuse ≥ ua haujlwm tam sim no / 0.9. (2) Qhov kub thiab txias: Qhov ntsuas kev nqa khoom tam sim no ntawm qhov fuse yog ua tiav ntawm qhov chaw siab ntawm 25 ℃. Qhov siab dua qhov kub nyob ib puag ncig, lub neej luv luv ntawm lub fuse, thiab qis dua nqa lub peev xwm. Yog li no, qhov kub thiab txias thiab qhov chaw ib puag ncig yuav tsum txiav txim siab thaum xaiv qhov fuse. Cawv ntawm qhov kub ntawm lub peev xwm nqa khoom tam sim no yog raws li hauv qab no:
(3) mem tes: Cov mem tes yuav tsim cov hluav taws xob ua kom sov thiab ua kom lub cev muaj zog uas yuav cuam tshuam rau lub neej ntawm fuse. Lub plawv rau I2T yuav tsum tsim kom tsawg dua li cov nominal melting heat I2T ntawm lub fuse xav txog qhov muaj feem rau mem tes. Fuse rated I2T> tiag tiag pulse I2T / Pf Pf: cov ntsiab ntawm mem tes, uas sib txawv raws li tus lej ntawm cov mem tes uas tuaj yeem tiv taus, cov nqi tshwj xeeb muaj nyob hauv daim duab hauv qab no:
6. Kev Ntsuas Cov qauv ntsuas raug xaiv los ntawm cov txheej txheem saum toj no yuav tsum tau ntsuas hauv lub sijhawm tiag tiag los xyuas seb qhov kev xaiv fuse puas haum. Cov ntaub ntawv pov thawj no yuav tsum suav nrog kev sim nyob rau hauv ib txwm mob thiab kev txhaum kev ua kom paub tseeb tias cov fuse uas xaiv tau ua txoj haujlwm tiv thaiv hauv kev tiv thaiv Circuit Court.
