Voltage Drop Calculator
Kufungidzira voltage yarasikirwa pamwe chete waya kutamba kubva urefu, zvino uye conductor saizi.
Zvinyorwa zvinogadziridzwa paunenge uchinyora.

Zvimwe zvinobvunzwa zvakanyanya
Sei voltage kudonha inofungidzirwa?
Kune imwe-phase, Vdrop = 2 × ρ × L × I / A. The factor 2 accounts for the current traveling out and back; three-phase uses √3 instead of 2.
Chii voltage kudonha kunogona kubvumirwa?
A common rule of thumb ndechokuti ugare ne total drop pasi pe 3% ye branch circuits uye 5% overall.Larger conductors (bigger area) reduce the drop.
Copper kana aluminium - chii chinokosha?
Aluminium ine pamusoro 60% yepamusoro resistivity kupfuura kodhi, saka aluminium run of iyo imwechete saizi inotadza proportionally zvakawanda voltage.
Nei formula inoshandisa kaviri kureba?
Current anofanira kubuda kutakura uye kudzoka, saka imwe-phase circuit anoona kudonha kwevaviri conductors - saka chikonzero 2 × urefu. Three-phase circuits kushandisa √3 (anenge 1.732) panzvimbo, kuratidzwa geometry of balanced three-phase simba.
Ndiani anofanira kubvisa voltage?
Usashandisa mukuru conductor (kudzokorora cross-section zvakapetwa kaviri pamusoro kupera kudonha), kuderedza kutamba, kuparadza kutakura pamusoro parallel cables, kana kukwira voltage. Bigger copper ndeimwe yezvikonzero zvakajairika kubvisa sezvo kudonha iri inversely proportional kune nzvimbo.
Ndezvipi simba rakawanda rakarasikirwa mu cable?
The simba rakanga rarwadziwa ndechimwe nguva kudonha kwezvino, Ploss = Vdrop × I. A 3.5 V kudonha pa 20 A mvura 70 W semhepo mu waya - simba unobhadhara asi kamwe chete kushandisa, izvo ndezvipi zvachose nguva refu high-zvinofamba zvinopa chokwadi chikuru, pasi-kuora waya.
Ndinogona kushandisa AWG gauges sezvandinoda, asi ndisingafanirwe kushandisa mm²?
Yeah. Pick a gauge mu advanced AWG bhokisi uye inoshandura nzvimbo field ne cross-section yeiyo gauge mu mm² (eg 10 AWG ≈ 5.26 mm²), saka unogona kushanda mu gauge system North American vagadziri kushandisa.
API — kushandisa iyi kalkulator kubva code
Chiva iyi calculator semahara JSON endpoint - hapana chikuru zvinodiwa. Kutumira nzvimbo zviwanikwa pasi separameter query kana JSON. Chii zvachose chaunoisa kunze chinoshandisa default iyo peji iri rakasviba nayo; parameter isiri yechokwadi inonzi 400, uye haisi zero. Tora yakazara API docs →
