siab torque dc tsav tsav Circuit Court
Kev ua tau zoo ntawm DC tsav lub voj voog loj heev cuam tshuam rau tag nrho cov kev ua tau zoo. Muaj ntau yam teeb meem uas yuav tsum tau ua tib zoo tsim, xws li kev ncua sij hawm, kev tuav pov hwm kev tiv thaiv, kev tiv thaiv thiab kev tiv thaiv overcurrent, hloov zaus, thiab xaiv ntawm inductance ntxiv.
Lub voj voog uas tsis tshua muaj peev xwm siv tau H Huab Hwm Circuit Court Circuit raws li muaj hauv daim duab. UA thiab UB yog cov ua tiav kev sib txig sib txig sib luag lossis kev tsav tsheb uas tsis tsim nyog rau TTL ntau ntau. Lub qhov hluav taws xob ntawm qhov hloov qhov transistor yuav tsum siab tshaj 1.5 zaus Peb. Txij li high-power PNP transistors yog kim thiab tsis yooj yim rau siv, qhov no Circuit Court tsuas yog siv rau cov qes qes qes zog. Thaum cov keyboardskis muaj plaub ntu tagnrho NPN transistors, lub txoos theem hloov qhov teebmeem ntawm ob sab caj npab transistors (BG1 thiab BG3) yuav tsum tau daws. H-choj switching Circuit Court ntawm daim duab 2 siv cov qib hloov ntawm tus choj loj hauv transistor siv ob tug transistors. Txawm li cas los xij, qhov poob ntawm tus R resistor R loj, yog li nws tsuas yog siv tau rau hauv qis-tsav lub zog tsav.
Thaum tus tsav tsheb muaj zog, tus voltage ntawm tus npoo caj npab feem ntau kuj yog tus neeg siab, piv txwv li, qhov sib txuas ntawm lub zog muaj zog ncaj qha, ib theem 220V, los yog peb theem 380V. Rau kev nyab xeeb thiab kev cia siab rau, nws yog ntshaw kom insulate lub circuit Circuit Court (lub ntsiab Circuit Court) los ntawm kev tswj tuav. Txij ntawm no mus, lub voj voog loj yuav tsum siv lub ntab pem hauv ntej. Cov ntab ntiv nplhaib nyob sab hauv pom hauv daim duab 3 muaj kev ywj pheej ntawm txhua tus thiab tau txais los ntawm lwm cov khoom siv hluav taws xob. Txij li cov optocoupler siv nyob rau hauv lub voj voog ua ntej, tus tswj cov pa hluav taws xob tau raug hluav taws xob los ntawm txhua tus neeg tsav tsheb khiav ua ntej, yog li ua qhov teeb meem kev tswj fais fab (los yog tsis) rau lub ntsiab hluav taws xob.
