Yam ntxwv Ntawm Lub Tsheb Hluav Taws Xob Fuses

Feem ntau hais lus, hluav taws xob tsheb fuses yuav tsum muaj cov yam ntxwv hauv qab no:

1) DC tiv thaiv;

2) tuaj yeem tawg me me tam sim no;

3) tuaj yeem tiv taus cov kev poob siab tam sim no:

4) tuaj yeem tiv taus cov khoom thauj tam sim no thiab kub thiab txias;

5) Kev siv hluav taws xob tsawg, qhov kub tsis tshua muaj siab;

6) Raws li automotive-qib mechanical zog, kev co thiab kev poob siab; lwm.

Nyob rau hauv cov ntaub ntawv ntawm ib txwm siv hluav taws xob tsheb (EV) system, irregular surge tam sim no (los yog loj tam sim no) yuav tshwm sim nyob rau hauv ob lub ntsiab Circuit Court thiab txhua ceg Circuit Court. 8 mus rau 10 xyoo warranty. Qhov no xav kom EV fuses yuav tsum muaj zog tiv thaiv tam sim no, thiab kev pabcuam lub neej yuav tsum muaj tshaj 10 xyoo.

Nyob rau hauv cov kev tshwm sim ntawm ib tug luv luv Circuit Court nyob rau hauv lub EV system, txij li thaum lub luv luv-circuit tam sim no uas yuav tsum tau tso tawm los ntawm lub hwj chim roj teeb nws tus kheej tsis loj (raws li kev paub, qhov siab tshaj plaws luv luv tam sim no nyob rau hauv lub EV kev lag luam yog tsawg dua los yog sib npaug ntawm 12kA), yog tias lub hwj chim ntawm lub hwj chim roj teeb tsis tau them tag nrho, nws tuaj yeem tso tawm Thaum lub hwj chim ntawm lub roj teeb luv luv tsis puv, qhov luv-circuit tam sim no tuaj yeem tso tawm me dua - raws li kev paub dhau los, Qhov tsawg kawg nkaus tam sim no luv luv yog feem ntau 2kA ~ 4kA.

Raws li cov yam ntxwv ntawm EV daim ntawv thov, nws yog ib qho nyuaj rau kev lag luam kev tiv thaiv fuses lossis semiconductor tiv thaiv fuses kom tau raws li kev tiv thaiv kev xav tau ntawm EVs. Cov laj thawj tseem ceeb yog raws li hauv qab no:

1. aR (semiconductor short-circuit tiv thaiv) fuse: Raws li fuse IEC thiab UL cov qauv, tsuas yog thaum lub caij luv luv tam sim no siab tshaj 10In tuaj yeem aR fuse tawg qhov txhaum thiab sai. Tam sim no, qhov zoo dua aR fuses hauv kev lag luam fuse feem ntau tuaj yeem cuam tshuam qhov tam sim no ntawm 5 ~ 7In. Thaum qhov txhaum tam sim no tsawg dua 5In, lub fuse tsis tuaj yeem lav kev nyab xeeb tawg. Yog tias aR fuse raug siv ncaj qha rau kev tiv thaiv EV, tej zaum yuav muaj teeb meem xws li arcing ntawm lub fuse davhlau ya nyob twg, ua rau lub raj lub cev kub hnyiab, los yog hlawv;

2.gR fuse (fuse rau semiconductor overload thiab luv Circuit Court tiv thaiv): Raws li IEC thiab UL cov kev cai, cov pa fuse tam sim no ntawm gR fuse yog 1.6In, lub sij hawm fuse qub yog 1 teev, thiab lub sij hawm overload fusing yog qeeb dua. EV tiv thaiv cov cai. Yog tias gR fuse raug siv ncaj qha rau kev tiv thaiv EV, vim lub sijhawm tawg qeeb, qhov kub ntawm cov kab txuas nrog lub fuse yuav siab dhau, uas tuaj yeem ua rau hluav taws lossis puas tsuaj rau cov khoom siv peripheral.
