1, Muaj pes tsawg watts tuaj yeem nqa tau lub square xaim?

Ib" empirical formula" Feem ntau siv los ntawm cov kws tshaj lij hluav taws xob: tsuav yog nws yog cov tub ntxhais tooj liab hlau, tus ntoo khaub lig - thaj tsam ib square millimeter tuaj yeem nyab xeeb dhau los ntawm qhov ntsuas tam sim no ntawm 4 - 5a; Nyob rau hauv 220V ib - theem Circuit Court, tam sim no yog hais txog 4.5a rau txhua 1kW zog; Nyob rau hauv 380V peb - theem sib npaug Circuit Court, tam sim no yog hais txog 2a rau txhua 1kW zog. Cov txiaj ntsig saum toj no, uas tuaj yeem suav tau los ntawm cov qauv kev suav lub cev, nyob ze heev, yog li cov neeg siv hluav taws xob tuaj yeem nco qab cov no kom tsis txhob nco cov" cumbersome" xam cov qauv hauv lawv txoj haujlwm. Tom qab ntawd raws li cov txheej txheem no, peb tuaj yeem paub tias yog cov tub ntxhais tooj liab hlau nrog tus ntoo khaub lig - thaj tsam ntawm 1 mm2 yog siv nyob rau hauv 220V ib zaug - theem Circuit Court, nws tuaj yeem muaj kev nyab xeeb nqa tam sim no dhau los ntawm 1kW load; Yog hais tias nws yog siv nyob rau hauv lub Circuit Court ntawm peb - theem balanced load (xws li lub cev muaj zog), nws yuav xyuam xim nqa tam sim no dhau los ntawm 2.5kW load.

2, Muaj pes tsawg watts tuaj yeem nqa 1.5 square xaim?

Yog hais tias lub hwj chim kab yog ib tug tooj liab tub ntxhais hlau, ua ntej, qhov tso cai ua hauj lwm tam sim no yog 20a, piv txwv li 4400 watts thaum lub qhib hlau yog ntsia nyob rau hauv Z; Qhov thib ob yog zais cov yeeb nkab steel, nrog tam sim no ntawm 16a thiab lub zog ntawm 3520 watts; Qhov thib peb yog PVC raj concealed installation. Yog tias qhov tam sim no yog 14a, lub zog yog 3000 watts.

3, Muaj pes tsawg watts tuaj yeem thauj khoom ntawm 2.5 square?

Muaj pes tsawg kilowatts ntawm hluav taws xob 2.5 square meter xaim tau txais, lub teb chaws tus qauv GB4706 Raws li lub load tam sim no tus nqi ntawm cov xov hlau teev nyob rau hauv 1 - 1992 / 1998, tooj liab tub ntxhais hlau yog 2.5mm2, 16a ~ 25A yog hais txog 5500w, txhuas core hlau yog 2.5mm2, 13A ~ 20A yog hais txog 4400w, thiab 220VAC voltage tsis tshaj 10az tus qauv rau lub sij hawm ntev, thiab tsis pub tshaj 15A rau feem ntau ntawm cov sij hawm.

4, Muaj pes tsawg watts tuaj yeem nqa 4 square xaim?

Ib theem fais fab mov 1kW yog hais txog 4.5a, 8kw yog hais txog 36a. Lub peev xwm nqa tam sim no ntawm 4 square xov hlau (ib leeg yas tooj liab hlau) yog li 30a, uas yog me dua. Hloov 6 cov xov hlau square (ib lub zog siv hluav taws xob) Koj lub moos thiab tus nres yuav tsum nthuav dav. Koj tsis' tsis xav tau ntau lub zog. Z yog 4kw me me, uas yog OK. Muaj pes tsawg kilowatts ntawm hluav taws xob tuaj yeem tau txais los ntawm 4 square xaim? Nws nyob ntawm seb koj puas siv 220V hluav taws xob hauv koj tsev neeg lossis 380V hauv koj lub Hoobkas. Yog tias 4 square xaim ntawm 220 tuaj yeem thauj tau 6 mus rau 8 kilowatts.

5, Muaj pes tsawg watts tuaj yeem nqa 6 square xaim?

Muaj pes tsawg kilowatts tuaj yeem nqa tau 6 square xaim? Lub hwj chim kab txoj kab uas hla tsis ncaj qha cuam tshuam nrog lub zog xa mus. Feem ntau hais lus, 6 square xov hlau yog ntau tshaj li txaus rau cov xov hlau cua txias. 10X6 + 1x4 cables feem ntau yog siv rau kev kho fais fab ntawm qhov chaw tsim kho. Raws li qhov kev siv tam sim no, raws li kuv qhov kev tsim kho, hom kab no feem ntau tswj los ntawm 63A cua hloov. 6 square meters ntawm txhuas hlau tuaj yeem thauj khoom 6 kW, thiab 6 square meters ntawm tooj liab hlau tuaj yeem thauj khoom 10 kW.
