BYM3DC Series 1500V Photovoltaic Molded Case Circuit Breaker

Sena Molded Case Circuit Breaker e kopanya mekhoa ea ts'ireletso e tsoetseng pele ea bohlokoa bakeng sa lisebelisoa tsa motlakase tse nchafalitsoeng. E na le ts'ireletso ea nako e telele e lekantsoeng ka mokhoa o nepahetseng e thibelang ho senyeha ha conductor ho tsoa ho overcurrents e tsitsitseng, hammoho le ts'ireletso ea hang-hang ea potoloho e khuts'oane e tsamaeang ka har'a milliseconds nakong ea liketsahalo tsa phoso. Thermal-magnetic tripping machine e sebetsa e ikemetse mehloling ea matla a kantle, e netefatsa ts'ebetso e sa sireletsehang nakong ea tšitiso ea grid. Ka mesebetsi e 'meli ea feme e behiloeng ho litekanyetso tsa IEC, sekhechana se fana ka tšireletso e hokahantsoeng bakeng sa mabokose a kopanyang a PV, li-inverter le lits'ebetso tsa polokelo ea betri.

E fumaneha ka bobeli 2-pole (2P) le 3-pole (3P) tlhophiso, BYM3DC e ikamahanya le meaho e fapaneng ea sistimi. Moralo o kopaneng o ntlafatsa sebaka sa phanele ha o ntse o boloka tumello e felletseng ea 1500V. Thermoset ea eona e matlafalitsoeng ka fiberglass e fana ka matla a ikhethang a dielectric le ho hanyetsa ho senyeha ha UV, mocheso o feteletseng (-25 ° C ho ea + 70 ° C), le libaka tse senyang. Sistimi e potolohang ea khefutso e habeli e fihlella ho tima arc ka potlako ka ho kheloha matla a khoheli, e ka har'a li-arc chute tse tiisitsoeng tse thibelang ho phonyoha ha plasma.

Ho lumellana le litekanyetso tsa machaba tsa photovoltaic (IEC 60947-2, UL 489B) e tiisa boenjiniere ba tšireletso ea sehahi. The Molded Case Circuit Breaker e kenyelletsa mekhoa ea bopaki ba liteko e lumellang netefatso e bolokehileng ea ts'ebetso tlas'a mojaro. Lebokose la eona la ho qetela le tiisitsoeng ka makhetlo a mararo le thibela ho kenella ha lerole / mongobo (IP40), ha li-terminals tse fokolang tsa torque li thibela tšenyo ea conductor nakong ea ho kenya. Mamello ea mochini oa breaker e feta ts'ebetso ea 10,000 ka nako e felletseng, e netefatsang mashome a lilemo a ts'ebeletso e sa hlokeng tlhokomelo libakeng tse boima.

BYM3DC photovoltaic DC breaker ke ea bohlokoa bakeng sa lisebelisoa tsa sejoale-joale tsa letsatsi. E boloka likhoele tsa bohlokoa lipakeng tsa likhoele tsa PV le li-inverters, e sireletsa libanka tsa betri lits'ebetsong tsa polokelo, 'me e arola liphoso ho liphanele tsa kabo ea DC. Baenjiniere ba hlakisa tharollo ena bakeng sa motsoako oa eona o ke keng oa bapisoa oa mamello e phahameng ea motlakase (1500VDC), matla a hajoale a 800A, le theknoloji e inehetseng ea DC e fanang ka tšireletso e matla, e lumellanang le khoutu e hlokahalang bakeng sa mapolasi a letsatsi, marulelo a liindasteri le merero ea microgrid lefatšeng ka bophara.
