Tam sim no, qhov tsis txaus fais fab thoob ntiaj teb tab tom loj hlob zuj zus. Ntau lub tuam txhab thiab cov tib neeg xaiv yuav cov khoom siv hluav taws xob los pab txo cov kev txwv ntawm kev tsim khoom thiab lub neej vim tsis muaj fais fab. AC alternator yog ib qho tseem ceeb rau tag nrho cov khoom siv hluav taws xob. Yuav ua li cas xaiv cov alternators txhim khu kev qha, cov lus qhia hauv qab no yuav tsum tau sau tseg:
I. Cov yam ntxwv hluav taws xob:
1. Lub kaw lus txhawb zog: Nyob rau theem no, lub kaw lus txhawb zog ntawm lub tshuab hluav taws xob zoo tshaj plaws AC alternator yog tus kheej txhawb zog, uas feem ntau nruab nrog lub tshuab tswj hluav taws xob tsis siv neeg (AVR). Lub zog tso zis ntawm lub rotor exciter raug xa mus rau tus tswv tsev rotor los ntawm lub rectifier. Lub zog hloov kho hluav taws xob ruaj khov ntawm AVR feem ntau yog ≤1%. Ntawm lawv, AVR zoo kuj muaj ntau yam haujlwm xws li kev ua haujlwm sib luag, kev tiv thaiv zaus tsawg, thiab kev hloov kho hluav taws xob sab nraud.
2. Kev rwb thaiv tsev thiab kev pleev xim: Qib rwb thaiv tsev ntawm cov alternators zoo feem ntau yog chav kawm "H", thiab tag nrho nws cov khoom siv winding yog ua los ntawm cov ntaub ntawv tsim tshwj xeeb thiab impregnated nrog cov txheej txheem tshwj xeeb. Lub alternator khiav hauv qhov chaw nyuaj kom muab kev tiv thaiv.
3. Kev ua haujlwm winding thiab hluav taws xob: Lub stator ntawm lub alternator zoo yuav raug laminated nrog cov hlau txias-rolled phaj nrog siab magnetic permeability, ob-stacked windings, muaj zog qauv thiab zoo rwb thaiv tsev.
4. Kev cuam tshuam ntawm xov tooj: THF (raws li txhais los ntawm BS EN 600 34-1) yog tsawg dua 2%. TIF (raws li txhais los ntawm NEMA MG1-22) yog tsawg dua 50
5. Kev cuam tshuam xov tooj cua: Cov khoom siv brushless zoo thiab AVR yuav ua kom muaj kev cuam tshuam me ntsis thaum lub sijhawm xa xov tooj cua. Yog tias tsim nyog, tuaj yeem ntsia tau lwm yam khoom siv RFI suppression.
II. Cov yam ntxwv ntawm lub tshuab:
Qib kev tiv thaiv: Cov hom txheem ntawm txhua lub tshuab hluav taws xob AC hauv av yog IP21, IP22 thiab IP23 (NEMA1). Yog tias muaj qhov yuav tsum tau tiv thaiv siab dua, koj tuaj yeem xaiv txhim kho qib kev tiv thaiv ntawm IP23. Hom txheem ntawm lub tshuab hluav taws xob AC hauv dej hiav txwv yog IP23, IP44, IP54. Yog tias koj xav tau txhim kho qib kev tiv thaiv, xws li ib puag ncig yog ntug hiav txwv, koj tuaj yeem nruab lub tshuab hluav taws xob AC nrog lwm yam khoom siv, xws li cov cua sov hauv chaw, cov lim cua, thiab lwm yam.
Qhov tsis txaus fais fab thoob ntiaj teb ua rau kev muag khoom ntawm AC alternator / generators nce ntxiv heev. Cov nqi ntawm cov khoom siv AC generator xws li disc couplings thiab rotors tau nce siab thoob plaws lub rooj tsavxwm. Kev muab khoom tsawg heev. Yog tias koj xav tau hluav taws xob, koj tuaj yeem yuav AC generators sai li sai tau. Tus nqi ntawm AC generators kuj nce ntxiv tas li!
