Saamaynta awooda ee ku taal madax-bannaan

Qeexitaanka awooda waa xudunta muhiimka ah ee laambada laambada, dhib malahandib u soo celin kara laambadahaama laambada qallalan. Marka aynu fahanno waxa awooda awooda ahi yahay.

1, Awoodda
Arrinta awooda ayaa lagu gartaa awoodaMadaxa hogaamiyahasi loo soo bandhigo awoodda firfircoon. Awooddu waa cabirka heerka gudbinta tamarta, iyo wareegga DC waa wax soo saarka korantada iyo hadda nidaamka aC, kaas oo ka dhigaya awooda hadda jira (Volt Volds), Volt Volt by Amps hadda jira). Farqiga u dhexeeya awoodda muuqaalka ah iyo awoodda dhabta ah waxay horseedaa qodobka awoodda, iyo qodobka awoodda ayaa la mid ah saamiga awooda dhabta ah ee awoodda muuqata. Markaa awoodda dhabta ah ee nidaamka AC waxay la mid tahay wakhtiyada korantada ee ku tiirsan qodobka awoodda.
Taasi waa: Qeybta Awoodda = Awoodda dhabta ah / Awoodda muuqata. Kaliya qodobka awooda ee xayiraada toosan sida kuleylka korantada iyo nalka nalka waa 1.

2, awood muuqata
Awoodda firfircoon: wax soo saarka AC-ga iyo AC hadda. Qaaciddada sida: s = ui. Meesha loo yaqaan 'the s' lagu qiimeeyo awoodda wax soo saarka ee Va (volt-ampere); U waa la qiimeeyay korantada ee V, sida 220V, 380V, iwm .; Waxaa layga soo saaray wax soo saarka ee hadda jira ee A. Awoodda muuqata waxay ka kooban tahay laba qaybood: awood firfircoon (P) iyo awoodda firfircoon (Q). Awoodda firfircoon waxay tixraacaysaa qaybta shaqada si toos ah loo qabtay. Tusaale ahaan, iftiinka kor u qaadida, wareegga gawaarida, shaqada wareegga elektiroonigga ah. Sababta oo ah awooddani waxay noqotay kuleyl, waxaa si toos ah loogu dareemi karaa dadka, sidaa darteed dadka qaarkiis waxay leeyihiin khayaali, taasi waa awooda firfircoon ee awoodda muuqata, kaasoo yaqaan awooda firfircoon waa qeyb ka mid ah
Awoodda muuqata, oo leh qaaciddada: P = Scos θ = ucosθ = uif. Halkaas oo P ay tahay awooda firfircoon ee w (watts); F = COS θ waxaa loo yaqaanaa awoodda awoodda, iyo θ waa farqiga wejiga ee korantada vetal ee kala duwan ee korantada aan tooska ahayn. Awoodda falcelinta ayaa ah qaybta awoodda lagu keydiyo wareegga laakiin si toos ah uma shaqeynin, oo lagu muujiyey qaaciddada: q = SSIN θ = uininθ. Halkee q waa awooda falcelinta ee Var (la'aan).

Loogu tala-galayMadax-xirtaiyo dhammaan wareegyada kale ee elektiroonigga ah ee ka shaqeeya korantada DC, ma ahan wax aan macquul aheyn in la shaqeeyo iyada oo aan lahayn awood la'aan.
