Kodi magetsi a DC amagwira ntchito bwanji?

DC mphamvuali ndi ma elekitirodi awiri, zabwino ndi zoipa.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.

TheDC systemamagwiritsidwa ntchito m'mafakitale amagetsi a hydraulic ndi matenthedwe 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, UPS, kulumikizana ndi ma subsystem ena.

Pali mfundo ziwiri zogwirira ntchito, imodzi ndiyo kugwiritsa ntchito mphamvu zamagetsi kutembenuza AC kukhala DC;ena amagwiritsa ntchito 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 ndi fyuluta ①, voteji yomwe imapezeka imakhala yokhazikika ndipo magetsi a DC omwe ali ndi phokoso laling'ono amadutsa mu chubu lamphamvu kwambiri lomwe limayendetsedwa ndi dera lowongolera kuti lifunse molondola komanso mwamsanga kuthamanga kwapamwamba, ndi kulondola kwa kayendetsedwe ka magetsi ndi ntchito zidzakwaniritsa muyeso.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 mtengo wamagetsi 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.Magetsi okhazikika a DC amatha kutulutsa ma voliyumu ndi zomwe timayika pano, ndipo nthawi yomweyo, dera lowongolera / chitetezo likazindikira ma voliyumu achilendo kapena mayendedwe apano, gawo lodzitchinjiriza lidzayatsidwa kuti magetsi a DC alowe mu chitetezo boma.

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.Busbar yotseka imapereka mphamvu ku basbar yolamulira kudzera pa chipangizo chotsika (zojambula zina sizifuna chipangizo chotsika).
