Transformer yog dab tsi?
Lub transformer yog ib qho khoom siv hluav taws xob passive uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction kom hloov hluav taws xob hluav taws xob los ntawm thawj lub voj voog mus rau theem nrab. Nws lub peev xwm los kho cov qib voltage ntawm cov circuits yog qhov tseem ceeb, ua kom muaj txiaj ntsig zoo thiab xa hluav taws xob hluav taws xob.
75 kVA Transformer Dimensions
| Dimension | Metric (mm) | Imperial (nti) |
|---|---|---|
| Qhov siab (H) | 1 092mm | 43″ |
| Dav (W) | 6 10mm | 24″ |
| Qhov tob (D) | 5 08mm | 20″ |
🔧 Installation Note:Qhov no 75 kVA transformer hnyav 500 lbs thiab yuav tsum tau forklift lossis crane rau kev teeb tsa. Ua ntej- npaj kev nkag mus thiab txheeb xyuas cov peev txheej hauv pem teb (tsawg kawg 750 lbs pom zoo). Cia 24-48 teev rau kev kho pob zeb yog tias cov ntaub qhwv tshiab tau nchuav.

Puv Load Amps ntawm Ntau Qhov Voltages
Cov lus hauv qab no qhia tau hais tias suav tag nrho load amperage rau 75 kVA peb-theem transformer:
| Qhov hluav taws xob | Puv Load Amps | Pom zoo Hlau Loj |
|---|---|---|
| 120V | 360.9 A | 500 MCM |
| 208V | 208.2 A | 250 MCM |
| 240V | 180.4 A | 4/0 AWG |
| 277V | 156.3 A | 3/0 AWG |
| 480V | 90.2 A | #2 AWG |
| 600V | 72.2 A | #3 AWG |
Formula siv:
Peb-Phase: Amps=(kVA × 1000) ÷ (Voltage × 1.732)
Piv txwv ntawm 480V: 90.2 A=(75 × 1000) ÷ (480 × 1.732)
Hluav taws xob Specifications

|---|---|---|
| Rated kVA | 75 kVA ua | Ntawm qhov ntsuas voltage thiab zaus |
| Ntau zaus | 60 Hz | 50 Hz muaj nyob ntawm kev thov |
| Tsis muaj -Load Poob | 180 W | Core/hlau poob (tseem) |
| Load Loss | 700 W | Copper poob ntawm 100% load |
| Tag nrho Losses | 880 W | Thaum 100% load |
| Impedance | 4.5% | ± 7.5% kam rau ua rau IEEE |
| Kev ua tau zoo | 98.7% | Thaum 100% load |
| Suab Level | ~ 41 dB | Rau NEMA ST-20 (kwv yees) |
⚠️ Kev txiav txim siab tseem ceeb rau 75 kVA Transformers:
Ntawm 75 kVA, xyuas kom muaj qhov cua kom txaus (tsawg kawg 3 "sab, 6" sab saum toj) kom txias kom zoo.
Kev sib piv impedance yog qhov tseem ceeb thaum sib piv cov transformers. Tham nrog tus kws tshaj lij tshuab hluav taws xob.
Thaum twg yog 75 kVA Peb -Theem Transformer Txoj Cai Xaiv?
A 75 kVA peb-theem transformeryog zoo tagnrho rau:
- Cov chaw tsim khoom me me nrog cov khoom siv 3-theem
