Dab tsi yog cable loj rau 50kW lub cev muaj zog?

Lub Cable loj yuav tsum muaj rau lub cev muaj zog 50kW yog nyob ntawm ntau yam, suav nrog cov hluav taws xob theem, thauj khoom ntev, thiab cov lus tso cai tam sim no. Feem ntau, xaiv cov cables ua raws cov kauj ruam hauv qab no:

1. Xam cov tam sim no: Ua ntej, laij cov tam sim no raws li lub zog thiab hluav taws xob ntawm lub cev muaj zog. Noj 380V peb-lub cev muaj zog ua ib qho piv txwv, cov cai txheej txheej tam sim no muaj raws li hauv qab no:

Taking a 380V three-phase motor as an example, the current calculation formula is

Qhov twg:

P yog fais fab (50kw),
Koj yog voltage (380v),
Cosφ yog lub hwj chim ua kom zoo (xav tias yog 0. 8).

Cov kev suav ua yog kwv yees li:

Motor operating current

Yog li ntawd, kev ua haujlwm tam sim no ntawm lub cev muaj zog yog txog 95.5A.

2. Xaiv cov cable loj: Xaiv cov cable tsim nyog raws li qhov tam sim no. Feem ntau hais lus, txoj hlua cable sib raug rau tam sim no ntawm 95.5A feem ntau yog muaj ib qho kev xaiv nyob rau ntawm cov kab ntsig, ntsuas kub thiab lwm yam). Rau cov thawj coj coining, loj dua cov lus qhia loj xws li 120mm² lossis 150 hli feem ntau raug xaiv.

3. Xav txog kab poob thiab voltage poob: Cov xwm txheej ntev ntev, cov voltage poob ntawm lub cable tej zaum yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, thiab cov kev tso tawm feem ntau yuav tsum tau ua ntau tshaj 3%. Yog li ntawd, thaum kis dhau mus deb, nws yuav tsim nyog los xaiv ib qho loj dua cable.

Hauv ntej, rau lub cev muaj zog 50kW lub cev muaj zog, cov hom cable loj yog 70mm² rau 95mm² Tooj Liab Cable, thiab cov lus qhia tshwj xeeb yog hloov kho raws li cov xwm txheej thiab cov kev xav tau ntawm kev siv. Yog tias koj xav paub ntxiv cov kab cab, nws raug nquahu kom xa mus rau cov khoom siv cable yog cov ntaub ntawv tsim hluav taws xob tshwj xeeb.
