PV array DC isolator switch, joalo ka ha lebitso le fana ka maikutlo, ke switch e khethollang DC.E sebelisoa haholo lits'ebetsong tsa liteishene tsa motlakase oa photovoltaic, 'me e sebelisoa lipakeng tsa li-high-voltage DC photovoltaic arrays le li-inverters tse amanang le grid ho khaola li-arcs tse hlahisoang ke matla a DC, ho qoba likotsi tse kotsi, le ho netefatsa ts'ebetso e sireletsehileng.Li fumaneha haufi le inverter 'me li hloka mokhoa oa ho arola sehlopha sohle sa PV nakong ea ho kenya sistimi kapa tlhokomelo efe kapa efe e latelang.
Mesebetsi ea Tšireletso ea PV Array DC Isolator Switch ke efe?
(1) Ha u kenya mochine oa photovoltaic, mochine o atisa ho tima mochine oa DC pele ho arola ho kenya letsoho la motlakase oa letsatsi ho tloha ho inverter.Nakong ena ea wiring le plugging ea li-terminals tsa DC, matla a DC ha a kopane le lehlakoreng la DC la inverter ho thibela ts'oaetso ea motlakase ea motho ka mong le ho senya thepa ea motlakase le ea morao-rao.Ka hona, ha re kenya sistimi, re hloka PV array dc isolator ho arola matla a DC lipakeng tsa inverter le betri.
(2) Setsing sa motlakase sa photovoltaic, inverter ke "setsi sa mantlha".E le ho netefatsa nako e lekaneng ea ho hlahisa matla, inverter ha e na konopo ea ho qala ho emisa.Hafeela ho ntse ho e-na le leseli (esita le ha pula e na), lisebelisoa tsa letsatsi li ka hlahisa motlakase 'me inverter e ka sebetsa ka bo eona.Leha ho le joalo, sena se boetse se hlahisa bothata.Ha o nkela sebaka kapa o lokisa inverter, leha lehlakore la AC le khaotsoe ke sekhechana sa potoloho sa AC se kentsoeng, lehlakore la DC le lula le matlafatsoa.Tabeng ena, haeba inverter e se na sesebelisoa sa solar array dc isolator ho arola matla a DC a liphanele, ho bonolo ho baka ts'oaetso ea motlakase le tšenyo ea lisebelisoa.
(3) Hona joale, boholo ba li-inverters tse marakeng ke tsa letoto la TL, ke hore, ha ho na motlakase o ikemetseng ka hare, 'me ho na le monyetla oa ho phalla ka morao ho tloha lehlakoreng la AC ho ea lehlakoreng la DC.Nakong ea tlhokomelo, haeba switch ea AC le switch ea DC li arohane ka 'mele, li ka sireletsoa ka mokhoa o sireletsehileng haholoanyane.
Mefuta e fapaneng ea ho kenya
Ho na le mefuta e 5 ea ho kenya: Mofuta oa ho kenya lekoti le le leng, Mofuta oa ho kenya Panel, Mofuta oa ho kenya seporo, Mofuta oa ho kenya linotlolo tsa mamati, le mofuta oa ho kenya kantle.
Likarolo tsa Slocable PV Array DC Isolators:
1. Haholo-holo e etselitsoeng kopo ea DC, e lekantsoeng ka mefuta ea hona joale ea 16 ~ 630A, marang-rang: ≤1500V, e loketseng likopo tse sa tšoaneng;
2. Mekhoa e fapaneng ea ho kenya le moralo oa modular o fa sehlahisoa ho fetoha ha maemo;
3. Moralo oa ho itlhoekisa oa motlakase, o fokotsa ho hanyetsa le tšebeliso ea matla, le ho lelefatsa bophelo ba tšebeletso;
4. Palo ea lipalo: 2 ~ 10 maemo a boikhethelo;
5. Nako e phahameng ea ho tima: ka tlase ho 5ms
6. Ho sebelisoa thepa e thibelang lelakabe ea UL94V-0 e tsoang kantle, e ka sebelisoang libakeng tse thata tsa kopo;
7. Ikamahanye le litekanyetso tse fapaneng (tse kang IEC, UL, TUV, CE, CB, SAA, CCC, joalo-joalo)
Slocable e ka hlahisa li-isolators tsa PV tse loketseng mefuta e fapaneng ea li-inverters tsa likhoele ho tloha ho 1KW ho isa ho 320KW.Ke mofani oa li-switch tsa DC isolator ho latela IEC60947-3(ed.3.2):2015 mme o fumane setifikeiti sa UL.
Lihlahisoa tsena tse lumellanang le litekanyetso tsa morao-rao tsa photovoltaic li ka finyella litlhoko tse pharaletseng tsa 'maraka oa photovoltaic oa lefats'e' me li ka rarolla mathata a bareki mabapi le polokeho le tšireletso ea tsamaiso.Slocable e tla tsoelapele ho etsa lipatlisiso tse tebileng ho fa 'maraka likhetho tse fapaneng le tse betere.
