Kodi makina amagetsi a DC amagwira ntchito bwanji?

Mphamvu ya DC ili ndi ma electrode awiri, abwino ndi oipa. Mphamvu ya electrode yabwino ndi yayikulu ndipo mphamvu ya electrode yoipa ndi yochepa. Pamene ma electrode awiriwa alumikizidwa ku dera, kusiyana kosalekeza kwa mphamvu kumatha kusungidwa pakati pa malekezero awiri a dera, kotero kuti mu dera lakunja A current imayenda kuchokera ku zabwino kupita ku zoipa. Kusiyana pakati pa mulingo wamadzi kokha sikungasunge kuyenda kwa madzi kokhazikika, koma mothandizidwa ndi pampu kuti madzi atumize nthawi zonse kuchokera pamalo otsika kupita pamalo okwera, kusiyana kwina kwa mulingo wamadzi kumatha kusungidwa kuti pakhale kuyenda kwa madzi kokhazikika.

Dongosolo la DC limagwiritsidwa ntchito m'malo opangira magetsi a hydraulic ndi thermal komanso m'malo osiyanasiyana osinthira magetsi. Dongosolo la DC limapangidwa makamaka ndi mabatire, zida zochapira, mapanelo odyetsa a DC, makabati ogawa a DC, zida zowunikira mphamvu za DC, ndi ma feeder a nthambi ya DC. Netiweki yayikulu komanso yogawa magetsi ya DC imapereka mphamvu yogwira ntchito yotetezeka komanso yodalirika pazida zotetezera ma relay, kutsekeka ndi kutseka kwa circuit breaker, machitidwe a chizindikiro, ma charger a DC, kulumikizana kwa UPSc ndi njira zina zazing'ono.

Pali mfundo ziwiri zogwirira ntchito, imodzi ndi kugwiritsa ntchito mphamvu yamagetsi posintha AC kukhala DC; inayo imagwiritsa ntchito DC

AC kupita ku DC

Pamene magetsi akuluakulu asinthidwa kukhala magetsi opangidwa kudzera mu switch yolowera ndipo transformer ikayatsidwa, imalowa mu dera lokhazikika. Dongosolo lokhazikika limayamba kugwira ntchito yolamulira magetsi oyamba pa magetsi otuluka omwe mukufuna, ndipo cholinga chake ndikuchepetsa kusintha kwa mphamvu yayikulu. Kutsika kwa magetsi pakati pa magetsi olowera ndi otuluka a chubu kumatha kuchepetsa kugwiritsa ntchito mphamvu kwa chubu chowongolera mphamvu yayikulu ndikuwonjezera magwiridwe antchito a magetsi a DC. Kukhazikitsa mphamvu yamagetsi. Pambuyo podutsa magetsi olamulidwa kale ndi kusefa, magetsi omwe apezeka amakhala okhazikika ndipo magetsi a DC okhala ndi ripple yaying'ono amadutsa mu chubu chowongolera mphamvu yayikulu chomwe chimayendetsedwa ndi dera lowongolera kuti afunse molondola komanso mwachangu kuthamanga kwamagetsi apamwamba, ndipo kulondola ndi magwiridwe antchito a magetsi kudzakwaniritsa muyezo. Magetsi a DC atasefedwa ndi fyuluta 2, mphamvu ya DC yotuluka yomwe ndikufunika imapezedwa. Kuti tipeze mtengo wamagetsi otuluka kapena mtengo wamagetsi wokhazikika womwe ndikufunika, tiyeneranso kuyesa ndikupeza mtengo wamagetsi otuluka ndi mtengo wamagetsi. Ndipo ikaitumiza ku dera lowongolera/kuteteza, dera lowongolera/kuteteza limayerekeza ndikusanthula mtengo wamagetsi otulutsa omwe apezeka ndi mtengo wamagetsi ndi mtengo wamagetsi womwe wakhazikitsidwa ndi dera lowongolera magetsi/magetsi, ndikuyendetsa dera lowongolera magetsi loyambirira ndi chubu chosinthira champhamvu kwambiri. Mphamvu yokhazikika ya DC imatha kutulutsa mphamvu ndi mtengo wamagetsi womwe timayika. Ndipo nthawi yomweyo, dera lowongolera/kuteteza likazindikira mphamvu yamagetsi yosadziwika bwino kapena mtengo wamagetsi, dera loteteza lidzayatsidwa kuti magetsi a DC alowe mu mkhalidwe woteteza.

Mphamvu yamagetsi ya DC

Mizere iwiri yolowera ya AC imatulutsa AC imodzi (kapena mzere umodzi wolowera wa AC) kudzera mu chipangizo chosinthira kuti ipereke mphamvu ku gawo lililonse lochaja. Gawo lochaja limasintha mphamvu ya AC ya magawo atatu kukhala mphamvu ya DC, limachaja batri, ndikupereka mphamvu ku katundu wotseka basi nthawi imodzi. Galasi lotseka basi limapereka mphamvu ku bala lowongolera basi kudzera mu chipangizo chotsika (mapangidwe ena safuna chipangizo chotsika)

Mphamvu yamagetsi ya DC

Gawo lililonse lowunikira mu dongosololi limayang'aniridwa ndi kuyendetsedwa ndi gawo lalikulu lowunikira, ndipo chidziwitso chomwe chimasonkhanitsidwa ndi gawo lililonse lowunikira chimatumizidwa ku gawo lalikulu lowunikira kuti liyang'anire mogwirizana kudzera mu mzere wolumikizirana wa RS485. Chowunikira chachikulu chimatha kuwonetsa zambiri zosiyanasiyana mu dongosololi, ndipo wogwiritsa ntchito amathanso kufunsa zambiri za dongosololi ndikuzindikira "ntchito zinayi zakutali pazenera lalikulu lowunikira kudzera pakugwira kapena kugwira ntchito kwa kiyi. Zambiri za dongosololi zitha kupezekanso kudzera pa mawonekedwe olumikizirana a kompyuta omwe ali pa chowunikira chachikulu. Dongosolo lowunikira kutali. Kuphatikiza pa gawo loyambira loyezera lonse, dongosololi likhozanso kukhala ndi mayunitsi ogwira ntchito monga kuyang'anira insulation, kuyang'anira batri, ndi kuyang'anira mtengo wosinthira, zomwe zimagwiritsidwa ntchito kuyang'anira bwino dongosolo la DC.
