Kugwiritsa ntchito ndi mawonekedwe a DC kudzipatula switch

Chosinthira chodzipatula cha DC ndi chida choletsa kuzungulira kwakanthawi pakati pa AC ndi DC ya DC kudzipatula switch. Imalumikizidwa ndi thiransifoma yodzipatula pakati pa cholumikizira magetsi cha AC motor power supply switch kabati ndi chingwe chamagetsi cha magawo atatu a AC, komanso kuyika kwamagetsi agawo atatu a AC. Mzerewu umalumikizidwa ndi mapindikidwe oyambira a chosinthira chodzipatula, ndipo kupendekera kwachiwiri kwa chosinthira chodzipatula kumalumikizidwa ndi malekezero amagetsi amagetsi amagetsi a AC.

Kusintha kwa DC kudzipatula kumathetsa dongosolo lowongolera la DC kudzipatula losintha muzojambula zam'mbuyomu. Chifukwa cha kuwonongeka kwa insulator pakati pa chipolopolo cha galimoto ya AC ndi njira yochepetsera mphamvu ndi mphamvu ya DC ndi zifukwa zina, mphamvu ya insulator imachepetsedwa, kapena pamene galimoto ya AC ikutha, ngozi zachifupi za AC ndi DC . Imateteza bwino ntchito yotetezeka ya zida zowongolera magetsi ndikuletsa kuwonongeka kwakukulu kwachuma komanso kuvulala kwamunthu.

Kuchuluka kwa ntchito

Chosinthira chodzipatula cha DC ndichoyenera kutetezedwa kudzipatula mumizere yokhala ndi ma voltages opitilira 1000VDC ndikuvotera mafunde mpaka 100A, ndikuzindikira kugawa katundu.

kusagwirizana ndi kudzipatula kothandiza. Amagwiritsidwa ntchito makamaka m'munda wa photovoltaic.

The DC kudzipatula lophimba makamaka oyenera makhazikitsidwe m'nyumba ndi AC 50/60Hz, oveteredwa voteji 1500V, pazipita voteji 1000V, ndi oveteredwa panopa 200A ndi 400A. Kuphatikiza pa kugwiritsidwa ntchito posinthira magetsi, ma switch opatula a DC amathanso kugwiritsidwa ntchito kupanga ndi kuswa mabwalo pafupipafupi.

Chofunika kwambiri ndi chakuti kugwiritsa ntchito bwino lusoli kumapangitsa kuti dziko lathu likhale ndi teknoloji yoziziritsa yamagetsi akuluakulu a hydro-generator opanda ufulu waumwini. Kumayambiriro kwa zaka za zana la 21 m'dziko langa, padzakhala majenereta ambiri akulu komanso akulu kwambiri omwe akudikirira kupangidwa ndi kupangidwa, ndipo kuziziritsa ndi imodzi mwamakina ofunikira kwambiri. Ubwino wopambana wa kusintha kotheratu, kotero kuti phindu lachuma ndi chikhalidwe cha anthu lidzakhala lalikulu.

Chosinthira cholumikizira cha DC chimachokera ku kaphatikizidwe ka makina amagetsi, kapangidwe ka mota, engineering thermophysics ndi dielectric electrochemistry, ndipo ili ndi zambiri. Komabe, kapangidwe kofunikira kuti muzindikire pagalimoto sizovuta, chifukwa chake kugwiritsa ntchito ukadaulo uwu ndikokulirapo. Nthawi zambiri, hydro-jenereta ndi mphamvu zoposa 200 megawatts akhoza kupeza zabwino zachuma ntchito luso. Kwa mayunitsi omwe amayamba pafupipafupi (monga makina opangira magetsi opopera) kapena amafunikira mphamvu zopanga kwambiri (kuphatikiza kukulitsa mphamvu), padzakhala zotsatira zabwino.
