Vim li cas cov fuses feem ntau tsis haum rau kev tiv thaiv kev tiv thaiv ntau dhau, tab sis feem ntau rau kev tiv thaiv luv luv? Lub sijhawm ua ke-cov yam ntxwv tam sim no piav qhia qhov laj thawj?
Ua ke ua ke ntawm lub sijhawm-tus cwj pwm tam sim no los piav qhia qhov laj thawj, peb yuav siv lub sijhawm-tam sim no tus yam ntxwv ntawm cov xov hluav taws xob qis uas yog qhov khoom siv ntawm kev sib tham thiab teb cov kauj ruam. Thawj saib ntawm ob peb lub tswv yim: 1. Dab tsi yog lub sijhawm-lub sijhawm tam sim no ntawm cov fuse hauv qab fusing cov kev mob, uas yog kev ua haujlwm ntawm lub sijhawm tam sim no xav tau (xws li lub sijhawm ua ntej arc lossis sijhawm fusing) 2. Lub sijhawm-pawg tam sim no nyob rau hauv cov kev cai, qhov ntau ntawm qhov tsawg kawg ua ntej-arc lub sijhawm-tus yam ntxwv tam sim no thiab qhov siab tshaj plaws fusing lub sijhawm-tam sim no tus yam ntxwv. Saum toj no ob lub ntsiab lus tuaj yeem hloov mus rau lub sijhawm-tam sim no tus xeeb ceem qhia hauv daim duab hauv qab no. Ua tib zoo mloog cov lus hauv lub thawv liab. Ob lub fuses F2 thiab F4 tau kos rau hauv daim duab. Peb tsuas yog saib ntawm F4 fuse, peb pom tias muaj ob lub loj thiab qis dua nkhaus, qhov twg 1 sawv cev qhov siab tshaj plaws ntawm lub sijhawm faus (nkhaus), 2 sawv cev rau qhov tsawg kawg nkaus pre-arc lub sijhawm (nkhaus), qhia tias lub sijhawm-tam sim no tus yam ntxwv nkhaus. ntawm F4 fuse muaj ob lub sijhawm Lub sijhawm tam sim no nyob ib puag ncig los ntawm lub sijhawm nkhaus, qee zaum peb pom tias lub sijhawm tam sim no tus yam ntxwv ntawm lub fuse muaj tsuas yog ib kab, tab sis qhov yuam kev tsis raug txiav txim siab.
Tom ntej no, cia wb mus saib qhov tseeb fuse lub sijhawm-tam sim no tus xeeb ceem nkhaus. Siv gG100 fuse ua piv txwv. Nws ntsuas tam sim no yog 100A. Thaum qhov tam sim no yog 200A, lub sijhawm siv sijhawm ntau ntawm 100 thiab 1000 vib nas this. Qhov no qhia tau hais tias gG100 fuse tuaj yeem siv Rau kev tiv thaiv kev tiv thaiv kev tiv thaiv.
Qhov tseeb, raws li tus qauv hluav taws xob tsawg fuse, lub fuse tau muab faib rau cov hom hauv qab no, gG hom fuse tsuas yog ib ntawm lawv, thawj tsab ntawv g sawv cev rau txhua qhov ntawm kev tawg, uas yog, tam sim no los ntawm kev pom zoo fusing. hluav taws xob tam sim no rau luv-Circuit Court tawg tam sim no Muaj peev xwm raug txiav tawm, ib qho sawv cev ib feem ntau tsis ua haujlwm; tsab ntawv thib ob sawv cev rau kev siv qeb, piv txwv li, G sawv cev rau lub hom phiaj fuse, uas yog siv los tiv thaiv cov xov hluav taws xob kis kab, M sawv cev tiv thaiv kev tiv thaiv lub cev muaj zog (M-motor), lwm hom muaj raws li cov npe hauv lub rooj, kuv yuav tsis txhob ua lawv.
Hauv qhov txheej txheem GB 13539.1-2015 Tsawg-Voltage Fuse Tshooj 1: Qhov Yuav Tsum Tau Ua, rau gG thiab gM hom fuses nrog kev tiv thaiv ntau yam, nws yog qhov yuav tsum tau los xyuas qhov kev xeem raws li kev pom zoo tsis fuse tam sim no thiab pom zoo fuse tam sim no, uas yog tiag kom paub tseeb tias cov fuse yog nyob rau hauv Fuse cov yam ntxwv hauv qab overload tam sim no. Rau lub fuse, hauv qhov tam sim no, nws tsis tuaj yeem tshuab hauv 1 teev, thiab nyob rau tam sim no, nws yuav tsum tshuab hauv 1 teev.
Cov fuses uas tsis haum rau kev tiv thaiv ntau dhau yeej yog aM fuses lossis lwm yam fuses uas lawv thawj tsab ntawv yog a. Piv txwv, qhov tsawg kawg nkaus fusing tam sim no ntawm aM fuse yog [qauv], yog li aM fuse thiab thermal relay yuav tsum tiv thaiv lub cev muaj zog ua ke, Lub thermal relay yog lub luag haujlwm rau kev tiv thaiv ntau dhau, thiab aM fuse yog siv rau kev tiv thaiv luv luv.
