Peb-theem hluav taws xob Load txuas
Muab faib ua daim duab peb sab txuas thiab Y txuas.
Kev thauj khoom ntawm txoj kev sib txuas ntawm delta yog peb txoj hlua nyob thiab ib lub hauv av xaim, qhov hluav taws xob nruab nrab ntawm peb cov xov hlau nyob yog 380V, thiab qhov hluav taws xob ntawm cov hlau nyob hauv av yog 220V.
Cov hlau lead ntawm Y-zoo li txoj kev sib txuas yog peb nyob ntawm cov xov hlau, ib qho nruab nrab hlau thiab ib qho av xaim. Qhov hluav taws xob nruab nrab ntawm peb txoj kab hluav taws xob nyob yog 380V, thiab qhov hluav taws xob ntawm cov xaim nyob rau hauv nruab nrab xaim lossis rau hauv av xaim yog 220V.
Tag nrho lub zog ntawm peb-theem hluav taws xob cov khoom siv hluav taws xob sib npaug yog sib npaug ntawm qhov hluav taws xob ntawm txhua theem muab faib los ntawm qhov tam sim no ntawm txhua theem thiab muab faib ua 3, uas yog, tag nrho lub zog=tam sim no × voltage (220V) × 3 ( W=U × I × 3)
Muaj peb hom hluav taws xob peb-theem: mechanical meter, zoo tib yam hluav taws xob meter thiab magnetic card electronic meter. Cov lus qhia dav dav yog: 1.5 (6), 5 (20), 10 (40), 15 (60), 20 (80), 30 (100) (voltage 3 × 380 / 220V ~).
Lus Cim: Lub nra ntawm lub ntsuas hluav taws xob tuaj yeem sib phim nrog cov kauj vab inductive ntawm qhov sib txawv hloov pauv kom tau raws li qhov yuav tsum tau siv. Piv txwv li, yog hais tias ib lub 'meter' nrog ib tug specification ntawm 3x1 (2) A yog siv rau tis inductance coils, thiab qhov inductance coil transformation piv yog xaiv li 1:50, qhov siab tshaj plaws ntsuas tam sim no uas yuav nqa tau los ntawm txhua theem yog 100A.
