Video: Yuav ua li cas koj xam cov hlau AWG?
2024 Tus sau: Taylor Roberts | [email protected]. Kawg hloov kho: 2023-12-16 00:29
AWG : Hauv Asmeskas Hlau Gauge ( AWG ) qhov system, hlau qhov loj me me tuaj yeem suav tau los ntawm kev siv cov mis D ( AWG )=. 005·92((36- AWG )/39) nti. Rau 00, 000, 0000 thiab lwm yam.
Ntawm no, AWG hauv kab ntawv yog dab tsi?
Yooj yim hais, AWG lossis Asmeskas tus xov tooj cua ntsuas cua yog tus txheej txheem txheej txheem uas txiav txim siab hla ntu ntawm cov hlau siv ntsuas ntsuas rau cov khoom sib hloov, cov xov hluav taws xob. Qhov siab dua AWG tus lej, cov xaim me me lossis xaim me dua. Siv txij li xyoo 1857, AWG tau pab cov neeg siv txiav txim siab xaim tam sim no-nqa kev ntsuas.
muaj pes tsawg amps tuaj yeem 2 AWG hlau tuav? Hlau Loj & Kev Ntsuas Amp
| Tooj liab | Aluminium | |
|---|---|---|
| Hlau Ntsuas Loj | 60 ° C (140 ° F) NM-B, UF-B | 90 ° C (194 ° F) XHHW-2, THHN, THWN-2 |
| 14 | 15 | --- |
| 12 | 20 | 25 |
| 10 | 30 | 35 |
Tom qab ntawd, lo lus nug yog, koj xam cov kab loj li cas?
Thauj Khoom Tam Sim No = (KVA · 1000) / (1.732 · Voltage): Tam Sim No Thauj Khoom = (100 · 1000) / (1.732 · 415) = 139 Amp.
Cia peb xaiv 3.5 tus tub ntxhais 70 Sq.mm cable rau ib leeg khiav.
- Tam sim no muaj peev xwm ntawm 70 Sq.mm cable yog: 170 Amp,
- Tag nrho derating tam sim no ntawm 70 Sq.mm cable = 170 · 0.93 = 159 Amp.
Kuv yuav siv xov tooj cua dab tsi?
Yam tsawg kawg nkaus hlau loj rau 30-amp, 240-volt Circuit yog 10- ntsuas , tab sis txhawm rau tiv thaiv kev ua haujlwm tsis zoo vim qhov poob qis, koj yuav tsum xav txog kev hloov kho rau 8- ntsuas yog tias lub qhov hluav taws xob nyob deb ntawm lub vaj huam sib luag. Rau 50-amp Circuit, koj xav tau 6- gauge xov yam tsawg kawg nkaus.

Koj xam xam lux thiab lumens li cas?
1 lx = 1 lm/mm2. 1 Lumen ib Square Meter: Lumen ib square meter sib npaug rau Lux (SI unit). Kev ntsuas tus naj npawb ntawm Lumens poob ntawm thaj tsam ntawm ib square meter, lub ntsiab lus ntawm Lux
Yuav ua li cas koj xam cov nqi ntawm cov nyiaj ntsuab?
Tus nqi nyiaj tiag tau suav los ntawm kev rho tawm tus nqi qis los ntawm kev hloov tus nqi thaum tus nqi qis yog xam los ntawm kev teeb tsa lub neej kev cia siab ntawm ib yam khoom thiab txiav txim siab qhov feem pua ntawm lub neej ntawd. Qhov feem pua ntawm no, sib npaug los ntawm tus nqi hloov pauv, muab tus nqi tiag tiag
Koj xam xam qhov nruab nrab qhov pom kev li cas?
Qhov nruab nrab qhov ci ntsa iab a = ntev ntawm chav nyob hauv meters; b = dav ntawm cheeb tsam hauv meters; h = nrug deb ntawm qhov nruab nrab ntawm cov teeb pom kev zoo thiab lub dav hlau uas koj yuav tsum ntsuas lub teeb pom kev zoo (piv txwv li qhov siab ntawm cov teeb pom kev zoo 2.80 m, qhov chaw ua haujlwm ntawm qhov siab 0.8 m, h = 2.80 txog 0.8 = 2)
Koj xam xam qhov chaw txav chaw nyob li cas?
Txhawm rau txiav txim siab qhov hloov chaw ntawm qhov chaw nres nkoj, peb tsuas yog muab thaj tsam hla ntu los ntawm qhov ntev ntawm qhov chaw nres nkoj (uas peb tau txiav txim siab ua 12 "hauv qhov piv txwv no.) Displaced Volume = 9.61625 X 12 = 115.395 cu.in
Koj xam xam pib lub zog ntawm lub cav li cas?
Raws li koj pom qhov sib npaug torque yog cov khoom ntawm lub zog thiab qhov kev ncua deb ntawm lub zog thiab qhov chaw ntawm kev sib hloov. Piv txwv li, yog tias koj xav tuav lub zog ua haujlwm ntawm qhov kawg ntawm rub, T = F x r
