Kesyon ki poze souvan

Ki jan se vòltaj pèt calculé?

Pou yon sèl faz, Vdrop = 2 × ρ × L × I / A. Faktori 2 kont pou koule a vwayaje deyò ak tounen; twa faz itilize √3 an plas de 2.

Ki kalite vòltaj tonbe se akseptab?

Yon règleman komen se pou kenbe total depase anba 3% pou branch circuits ak 5% an jeneral. pi gwo konduktè (pi gwo zòn) diminye depase.

Kouvwi oswa aliminyòm - li enpòtan?

Aluminim gen yon rezistans ki pi wo pase kouch kwiv, kidonk yon aliminyòm ki gen menm gwosè a pral pèdi plis vòltaj proportionnellement.

Poukisa fòmil la itilize de fwa longè a?

Konekte aktyèl la nan yon sèl faz nan yon lòt faz, yon sèl faz konvètisè a wè yon ti kras nan tou de konduktè yo - se konsa, faktè a 2 × longè. twa faz konvètisè a itilize √3 (sou 1.732) nan plas la, reflete jeometri a nan pouvwa a balans twa faz.

Ki jan mwen ka diminye yon gout vòltaj ki twò gwo?

Ou ka itilize yon kondui pi gwo (doubleman seksyon transverse a apwòch mwatye nan gout la), koutje sou kouri, divize chaj la sou kab paralèl, oswa ogmante vòltaj la. Pi gwo koube se fixation an komen paske gout la se invèrsement proportionnelle a zòn nan.

Ki kantite pouvwa a se pèdi nan kab la?

Enèji gaspiye se fwa yo tonbe nan koule a, Ploss = Vdrop × I. A 3.5 V tonbe nan 20 A gaspiye 70 W kòm chalè nan fil la - enèji ou peye pou men pa janm itilize, ki se poukisa long-wo-konpanse kouri justifier pi gwo, pi ba-pèt kab.

Èske mwen ka itilize AWG gauges an plas yon zòn mm²?

Wi. Chwazi yon mèt nan lis avanse AWG ak li retounen nan jaden zòn ak pati transverse a nan mèt sa a nan mm² (e.g. 10 AWG ≈ 5.26 mm²), se konsa ou ka travay nan sistèm mèt la itilize pa installateurs Amerik di Nò.
