100 KVA Distribution Transformer Rated Tam sim no

Dab tsi yog qhov ntsuas tam sim no ntawm 100 kva faib transformer? Muaj pes tsawg kilowatt loads tau ib 100KVA transformer nqa nyob rau hauv ib txwm ua hauj lwm?

1. Rated tam sim no ntawm 100 kva faib transformer

Ua ntej tshaj plaws, peb yuav tsum paub meej tias lub tshuab hloov pauv tsuas yog kho qhov voltage, thiab tswj tsis tau lub zog. Qhov ntawd yog hais tias, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm transformer yog ua raws li txoj cai ntawm kev txuag hluav taws xob.

Qhov thib ob, lub transformer yog ib qho khoom siv hloov pauv ntawm high voltage thiab low voltage. Yog li ntawd, qhov ntsuas tam sim no ntawm transformer tuaj yeem muab faib ua high-voltage sab tam sim no thiab qis-voltage sab tam sim no.

Qhov thib peb, tom qab nkag siab thawj ob lub ntsiab lus, peb yuav tsum paub cov qauv hloov dua siab tshiab, uas kuj yog cov qauv siv ntau tshaj plaws hauv lub zog:

Lub zog hluav taws xob (KVA)=kab hluav taws xob (KV) * kab tam sim no (A) * 1.732

Cia coj qhov kev hloov pauv voltage ntawm 10/0.4KV ua piv txwv los xam tus nqi tam sim no rau koj

1) High voltage sab tam sim no

Kab tam sim no (A)=100(KVA)/[10(KV)*1.732]=5.773(A)

2) Tsawg-voltage sab tam sim no

Kab tam sim no (A){{0}}(KVA)/[0.4(KV)*1.732]=144.34(A)

2. Muaj pes tsawg kilowatts ua lub 100KVA transformer nqa

Muaj pes tsawg kilowatt loads 100 kva tis transformer nqa? Cov qauv saum toj no yog pom tseeb tsis siv tau lawm. Kev xam kom raug yuav tsum paub txog qhov tsis zoo xws li lub zog hluav taws xob, hluav taws xob noj coefficient, thiab lwm yam. Cov txheej txheem no nyuaj heev. Muaj ib txoj kev kwv yees tus nqi qis:

Lub zog muaj zog (KVA) {{0}} lub zog (KW) / 0.8

Peb muab cov xwm txheej uas peb twb paub lawm rau hauv cov qauv thiab tau txais:

Lub zog muaj zog (KW) {{0}}(KVA) * 0.8=80(KW)

Qhov no yog tus nqi hluav taws xob uas tuaj yeem nqa tawm thaum lub tshuab hloov pauv tau khiav ntawm tag nrho cov load, tab sis cov kev cai cuam tshuam tau taw qhia tias lub sijhawm ua haujlwm puv sijhawm ntawm lub tshuab hloov pauv tsis tuaj yeem siab dua 80 feem pua ​​​​ntawm nominal peev xwm ntawm transformer. .

Raws li txoj cai no, cia ua qhov kev suav dua:

Lub zog ua haujlwm nyob rau hauv ib txwm ua haujlwm (KW) {{0}} (KVA) * 0.8 * 0.8=64 (KW)
