Kodi magetsi a DC amagwira ntchito bwanji?

Mphamvu ya DC ili ndi maelekitirodi awiri, abwino ndi oipa. Kuthekera kwa electrode yabwino ndipamwamba ndipo kuthekera kwa electrode yolakwika kumakhala kochepa. Pamene ma electrode awiriwa akugwirizanitsidwa ndi dera, kusiyana kosalekeza kumatha kusungidwa pakati pa malekezero awiri a dera, kotero kuti mu dera lakunja A panopa akuyenda kuchokera ku zabwino kupita ku zoipa. Kusiyanitsa pakati pa mlingo wa madzi pawokha sikungathe kusunga madzi okhazikika, koma mothandizidwa ndi mpope kuti atumize madzi mosalekeza kuchokera kumalo otsika kupita kumalo okwera, kusiyana kwina kwa madzi kungathe kusungidwa kuti apange madzi okhazikika.

Dongosolo la DC limagwiritsidwa ntchito m'mafakitale a hydraulic ndi matenthedwe amagetsi ndi malo osiyanasiyana. Dongosolo la DC limapangidwa makamaka ndi mapaketi a mabatire, zida zolipiritsa, mapanelo a DC feeder, makabati ogawa a DC, zida zowunikira magetsi a DC, ndi zodyetsa nthambi za DC. Network yayikulu komanso yogawidwa yamagetsi ya DC imapereka mphamvu zogwira ntchito zotetezeka komanso zodalirika pazida zodzitchinjiriza, kuyenda ndi kutseka kwa ma circuit breaker, makina amasigino, ma charger a DC, mauthenga a UPSc ndi ma subsystems ena.

Pali mfundo ziwiri zogwirira ntchito, imodzi ndiyo kugwiritsa ntchito mphamvu zamagetsi kutembenuza AC kukhala DC; ena amagwiritsa ntchito DC

AC mpaka DC

Mphamvu ya mains ikasinthidwa kukhala voteji yopangidwa kudzera pa chosinthira cholowetsa ndikuyatsa thiransifoma, imalowa mudera lokhazikika. Dongosolo lokhazikika la pre-stabilizing ndikukhazikitsa malamulo oyambira pamagetsi omwe amafunidwa, ndipo cholinga chake ndikuchepetsa kusintha kwamphamvu kwambiri. Kutsika kwamagetsi a chubu pakati pa kulowetsa ndi kutulutsa chubu kumatha kuchepetsa kugwiritsa ntchito mphamvu kwa chubu chowongolera mphamvu zambiri ndikuwongolera magwiridwe antchito amagetsi a DC. khazikitsani mphamvu yamagetsi. Pambuyo podutsa magetsi oyendetsedwa kale ndikusefa voteji yomwe imapezeka imakhala yokhazikika ndipo magetsi a DC omwe ali ndi phokoso laling'ono amadutsa mu chubu chowongolera mphamvu zomwe zimayendetsedwa ndi dera lolamulira kuti zifunse molondola komanso mwamsanga kuthamanga kwapamwamba, ndi kulondola kwa kayendetsedwe ka magetsi ndi magwiridwe antchito zidzakwaniritsa muyezo. Mphamvu ya DC ikasefedwa ndi fyuluta 2, mphamvu ya DC yomwe ndimafunikira imapezeka. Kuti tipeze mtengo wamagetsi otulutsa kapena mtengo wokhazikika womwe ndimafunikira, tifunikanso kuyesa ndikuzindikira kuchuluka kwa voltag ndi mtengo wapano. Ndi kuzitumiza ku control/protect circuit, control/protection circuit ikufanizira ndikusanthula mtengo wa voliyumu womwe wapezeka ndi mtengo wapano ndi mtengo womwe umakhazikitsidwa ndi voteji / pano, ndikuyendetsa dera loyang'anira komanso mphamvu yayikulu. chubu chosinthira. Mphamvu yamagetsi yokhazikika ya DC imatha kutulutsa ma voliyumu ndi zomwe timayika pano.ndipo nthawi yomweyo, gawo lowongolera / chitetezo likazindikira ma voliyumu achilendo kapena mayendedwe apano, gawo lodzitchinjiriza lidzayatsidwa kuti magetsi a DC alowe m'malo otetezedwa. .

Mizere iwiri ya AC yomwe ikubwera imatulutsa AC imodzi (kapena mzere umodzi wokha wa AC) kupyolera mu chipangizo chosinthira kuti chipereke mphamvu ku gawo lililonse lopangira. Gawo lolipiritsa limasintha mphamvu ya magawo atatu a AC kukhala mphamvu ya DC, kulipiritsa batire, ndikupatsa mphamvu pamabasi otseka nthawi yomweyo. Malo otsekera mabasi amapereka mphamvu kumalo owongolera mabasi kudzera pa chipangizo chotsikira pansi (mapangidwe ena safuna chipangizo chotsitsa)

Gawo lililonse loyang'anira dongosololi limayendetsedwa ndikuyendetsedwa ndi gulu lalikulu lowunika, ndipo zomwe zimatengedwa ndi gulu lililonse lowunika zimatumizidwa kugawo lalikulu loyang'anira kasamalidwe kogwirizana kudzera munjira yolumikizirana ya RS485. Chowunikira chachikulu chimatha kuwonetsa zambiri m'dongosolo, ndipo wogwiritsa ntchito amathanso kufunsa zambiri zamakina ndikuzindikira "ntchito zinayi zakutali pachiwonetsero chachikulu chowonera kudzera pakukhudza kapena makiyi. Zambiri zamakina zitha kupezekanso kudzera mu mawonekedwe olumikizirana apakompyuta omwe ali pagulu lalikulu lowunikira. Kuphatikiza pa kuyeza kokwanira koyambira, makinawo amathanso kukhala ndi magawo ogwirira ntchito monga kuwunika kwa insulation, kuyang'anira mabatire.
