1000V DC Molded Case Circuit Breaker

E etselitsoe litlhoko tse boima tsa lisebelisoa tsa motlakase tse tsosolositsoeng, CDADA DAM3PV Series 1000V DC Molded Case Circuit Breaker e fana ka tšireletso e matla le e khuts'oane ho li-grids tsa motlakase tsa DC le photovoltaic (PV) ho fihla ho DC 1500V le 800A. Shanghai DADA Electric CO., LTD., joalo ka moetsi, DC MCCB ea rona ea ts'ebetso e phahameng e ntlafalitsoe ka ho khetheha bakeng sa mapolasi a letsatsi, limela tsa polokelo ea betri, lisebelisoa tsa ho tjhaja EV, le li-microgrid tsa DC tsa indasteri.

Ho fapana le li-breaker tsa AC, letoto la DAM3PV le na le sistimi e ikhethileng ea ho tima li-arc e thibelang ka mokhoa o sireletsehileng li-arcs tsa DC tse nang le matla a mangata-a bohlokoa lits'ebetsong moo motlakase o lulang o le teng mme li-arcs li sa itime. Ka litekanyo tse lekantsoeng tsa ho sebetsa tsa 1000V kapa 1500V DC, e ts'ehetsa meralo ea letsatsi ea bolulo / ea khoebo (1000V) le ea lisebelisoa tsa letsatsi (1500V).

E fumaneha ho 2P, 3P, le 4P, DAM3PV e fana ka maqhubu a foreimi ho tloha 250A ho ea 800A le maqhubu a lekantsoeng a feto-fetohang (mohlala, 100A-250A bakeng sa 250-frame). E fana ka matla a ho qetela a ho roba ho fihla ho 40kA (ka li-voltage tse tlase) le 20kA ho 1000V/1500V DC, e netefatsa ho tlosoa ha liphoso ho tšepahalang esita le ka lihlopha tse kholo. The breaker e kenyelletsa ts'ebetso ea ho itšehla thajana, ts'ireletso ea IP20, 'me e ts'ehetsa ts'ebetso ea matsoho kapa ea motlakase, hammoho le maeto a thusang, a shunt, le mabitso a alamo bakeng sa ho lekola le ho laola hole.

E netefalitsoe ho ea ka litekanyetso tsa machaba 'me e hahiloe bakeng sa maemo a thata (Pollution Degree 3, -5°C to +40°C), CDADA DAM3PV ke khetho e bolokehileng, e scalable, le e loketseng bokamoso bakeng sa ts'ireletso ea matla a DC.
