Li-capacitor tsa YMIN li na le litšobotsi tse latelang tšimong ea converter
01. Matla a Phahameng
DC-Link capacitor e boloka matla a motlakase, e e nolofalletsang ho fana ka matla a tsoelang pele ho sistimi ea converter nakong ea liphetoho tse kholo tsa motlakase oa grid kapa ho tima ha motlakase, ho netefatsa ts'ebetso e tloaelehileng ea sistimi. Ntle le moo, ha sesebelisoa sa converter se hloka matla a mangata, DC-Link capacitor e ka lokolla matla a bolokiloeng ka potlako ho fihlela litlhoko tsa nakoana. Mejaro e nang le inductive joalo ka li-motors, capacitor e boetse e fana ka matšeliso a matla a sebetsang, e tsitsisa voltage, le ho ntlafatsa ts'ebetso ea makoloi. Sena se bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le botsitso ba sistimi.
02. Ultra-High Voltage Resistance
Li-capacitor tsa YMIN, tse nang le khanyetso ea matla a phahameng haholo, li ka sebetsa e le likarolo tse sireletsang. Nakong ea ts'ebetso ea converter, ba sireletsa lisebelisoa tsa elektroniki tse bobebe ts'enyong e bakiloeng ke li-voltage spikes. Sena se nolofalletsa li-converter tsa polokelo ea matla ho fana ka ts'ehetso e tsitsitseng ea voltage le frequency ho grid ea matla, ho netefatsa ts'ebetso e tšepahalang ea sistimi.
03. High Current Surge Resistance
Li-capacitor tsa YMIN ka katleho li monya maqhubu a phahameng a pulse a hlahisoang ke converter qetellong ea DC-Link, e nolofalletsang taolo e nepahetseng ea matla a hlahisoang ka taolo ea hajoale. Sena se tiisa hore converter e fihlela litlhoko tsa maemo a fapaneng mme e fana ka tlhahiso ea boleng bo holimo ea AC. Nakong ea ts'ebetso e bonolo ea ho qala li-converter, li-capacitor tsa YMIN li etsa karolo ea potoloho ea ho tjhaja, ho thusa ho thibela tšusumetso e feteletseng ho phepelo ea matla a ho kenya le mojaro.
04. Bophelo bo bolelele
Li-capacitor tsa YMIN, tse entsoeng ka lits'ebetso tse emeng 'me li behiloe litekong tse matla tsa pele ho tlhahiso, li na le letsoalo le phahameng le ho hanyetsa ha hona joale ho matla. Litšobotsi tsena li thusa li-converter lits'ebetsong tsa polokelo ea matla ho sebetsa ka mokhoa o tsitsitseng ka nako e telele, ho fokotsa ho hloleha le litšenyehelo tsa tlhokomelo.
