Ntxiv nrog rau kev ua kom ntseeg tau tias qhov ntsuas hluav taws xob yuav tsum siab dua qhov kev khiav hauj lwm qhov hluav taws xob thiab ua tib zoo saib xyuas qhov tsim nyog, qhov teeb meem tseem ceeb hauv kev xaiv EV fuses nyob hauv kev suav thiab xaiv cov ntsuas tam sim no.
Kal xal rated tam In of fuse: Ib=In x Kt x Ke x Kv x Kf x Ka;
Practical application can be converted to: In Greater than or equal to Ib/(Kt x Ke x Kv x Kf x Ka )
Hauv: Rated tam sim no ntawm lub fuse
Ib: Qhov siab tshaj plaws tso cai txuas ntxiv tam sim no ntawm lub voj voog uas lub fuse nyob
Kt: kub kho qhov tseem ceeb
Ke: Thaum tshav kub kub conduction yam ntawm cov khoom sib txuas
Kv: cua txias kho qhov tseem ceeb
Kf: zaus kho qhov tseem ceeb
Ka: altitude kho coefficient
Hauv kev siv cov tswv yim, qhov tseeb tam sim no nqa lub peev xwm ntawm fuses txawv raws li kev ua haujlwm sib txawv, thiab lub sijhawm sib txawv; Nws yog ib qho nyuaj rau siv tus qauv raug los txhais cov peev xwm nqa tam sim no ntawm fuses; cov neeg siv yuav tsum tau ua raws li lawv cov kev xaiv ntawm cov kev xaiv yooj yim thiab lawv tus kheej cov tswv yim tswj hwm sab hauv. Thaum kho qhov kev xaiv ntawm fuses, tsawg kawg yog cov hauv qab no yuav tsum tau xav txog:
Ø Txawm hais tias nws tuaj yeem tiv thaiv tau zoo, uas yog, seb lub fuse tuaj yeem ua haujlwm tau zoo thaum ntsib qhov luv luv hauv Circuit Court, thiab yuav tsis ua rau lub roj teeb pob hluav taws, hluav taws xob cable, thiab lwm yam.;
Ø Hauv kev siv cov tswv yim, seb qhov kub nce siab puas tuaj yeem ua tau, tswj tau, thiab seb nws puas cuam tshuam rau cov khoom siv peripheral;
Ø Kev ntsuas kev ua haujlwm tiag tiag yog qhov ntsuas tsuas yog los xyuas seb qhov kev xaiv puas haum.
