Li-capacitor tsa DC ho li-Inverter tsa Photovoltaic

Tlhahiso ea matla a letsatsi a photovoltaic e tla bapala karolo ea bohlokoa tšebelisong ea matla lefatšeng nakong e tlang e haufi, eseng feela ho nkela mehloli e meng ea matla a tloaelehileng sebaka, empa hape le ho ba mohloli o moholo oa phepelo ea matla lefatšeng.

Li-inverter tsa photovoltaic ke li-inverter tse fetolang motlakase o feto-fetohang oa DC o hlahisoang ke liphanele tsa letsatsi tsa photovoltaic (PV) hore e be motlakase o fetohang oa motlakase (AC), o ka fepuoang hape tsamaisong ea phetiso ea khoebo kapa oa sebelisoa tsamaisong ea kantle ho gridi. Kaha li-inverter hangata li sebelisoa maemong a kantle 'me li hloka ts'ebetso e tšepahalang ea nako e telele le tlhokomelo e fokolang, basebelisi ba ho qetela le baqapi ba na le litlhoko tse thata haholo tsa boleng le ts'epo bakeng sa likarolo tse sebelisoang lisebelisoa tsena. Jwalo ka mojari le tšehetso ts'ebetsong ea phetoho ea matla, li-capacitor tsa lifilimi li bapala karolo ea bohlokoa likarolong tsohle tsa li-inverter tsa photovoltaic. Haeba li sa khethoe hantle, li tla ba le tšusumetso e bolaeang botsitsong le bophelong ba lisebelisoa.

Bakeng sa tšebeliso potolohong ea inverter, ka kopo sheba mohlala oa ts'ebeliso setšoantšong se ka tlase:

Karolo ea capacitor ea DC-link:

1) Potolohong ea inverter, motlakase o hlahisoang oa rectifier o lokisoa le ho sefshoa haholo-holo;

2) Monya motlakase o nang le matla a phahameng a ho hema o kopiloeng ke inverter ho tsoa ho "DC-Link", o o thibele ho hlahisa motlakase o nang le matla a phahameng a ho hema holim'a impedance ea "DC-Link", 'me o boloke phetoho ea motlakase beseng ea DC ka har'a sebaka se lumelletsoeng;

3) Thibela ho phahama ha motlakase le ho phahama ha motlakase ka nakoana ha "DC-Link" ho ama IGBT.

Ka hona, litlhoko tsa li-capacitor:

1) Netefatsa hore motlakase o lekana ho mamella

2) Bokgoni bo lekaneng

3) Bokhoni bo lekaneng ba ho fetisa motlakase, ESR e tlase kamoo ho ka khonehang

4) Hloka litšobotsi tse ntle tsa maqhubu, ESL e tlase kamoo ho ka khonehang

5) Khotsofatsa boemo ba mocheso o matla o phahameng oa kantle le mongobo o phahameng oa kopo

Wuxi CRE New Energy Technology Co., Ltd. e ntse e shebane le ts'ebeliso ea li-capacitor tsa lifilimi ka har'a lisebelisoa tsa motlakase ka nako e telele. Ka sepheo sa ho sebetsana le boemo bo boima ba ts'ebeliso ho li-inverter tsa photovoltaic, e ipapisitse le theknoloji ea lifilimi e hanelang ho sebelisoa ke CRE e tšehetsoang ke DC, e sebelisa Polypropylene Dielectric e sa lahleheng haholo, e hanelang mocheso o phahameng, e entse moralo le nts'etsopele ea letoto la li-capacitor tsa lifilimi tse nang le mocheso o phahameng le khanyetso e phahameng ea mongobo, ESR e tlase (tlhahiso e tlase ea mocheso), ts'epo e phahameng le bophelo bo bolelele.
