Sida saxda ah ee loo doorto qaybaha beddelka ee foornada dhalaalidda induction
Sida saxda ah ee loo doorto qaybaha inverter foornada dhalinta dhalaalaysa
Guud ahaan, xaaladaha shaqada ee ka sarreeya 400HZ, qalabka KK waa in la tixgeliyaa; marka inta jeer ee uu ka sarreeyo 4KHz, qalabka KA waa la tixgelin karaa. Halkan waxaan inta badan ku soo bandhigaynaa xulashada qaybaha wareegga isbarbardhigga (eeg sawirka 1).
(1) Qaybaha hore iyo gadaal u roga danabka ugu sarreeya VDRM, qaybta VRMM ee hore iyo gadaal dambeedka korantada waa in ay ahaadaan 1.5-2 jeer ugu badnaan hore iyo gadaal gadaal. Iyadoo loo maleynayo in korantada wax soo gelinta DC ee beddelaadiyuhu uu yahay Ud iyo qodobka korontadu uu yahay cosψ, ka dib:
VDRM/RRM=(1.5-2)πUd/ (2cosψ)
(2) IT-ga hadda jirta ee gobolka (AV) ee qaybtu waxay ku xisaabtamaysaa in marka qaybtu ku shaqeyso soo noqnoqoshada sare, luminta beddelkeeda ay aad u muhiim tahay. Waqtiga xaadirka ah ee gobolka ee qaybtu waa inay socotaa 2-3 jeer qiimihiisu wax ku ool ah I marka loo eego xaqiiqada dhabta ah Si loo tixgeliyo, oo ah
IT (AV)=(2-3)I/1.57
Iyadoo loo maleynayo in wax-is-beddelka DC-ga hadda uu yahay Id, qalabka la doortay ee IT (AV) waa
IT (AV)=(2-3)×Id/ (1.57)
(3) Wakhtiga daminta tq wareegga isbarbar yaalka, wakhtiga daminta curiyaha KK waa in lagu doortaa iyadoo loo eegayo wakhtiga ka hor-kicinta tf iyo wakhtiga isku xirka tr. Guud ahaan qaado:
tq=(tf-tr)×
(Marka awooda korontadu ay tahay 0.8, tf waa qiyaastii toban meelood meel muddada, tr waxaa lagu go’aamiyaa curiyaha di/dt in ka yar ama la mid ah 100A/μS) Marka soo noqnoqoshada uu sarreeyo, wakhtiga isku xirka tr waa la dhimi karaa si habboon loo sadqeeyay Habka qodobka awoodda kordhinta tf si loo doorto qaybo leh qiimaha tq habboon
