DC MCB ke eng?
Sesebediswa sa DC miniature circuit breaker (MCB) ke sesebediswa se sireletsang se kgaolang potoloho ka boiketsetso ha ho fumanwa ho feteletsa kapa potoloho e kgutshwane. Ho fapana le disebediswa tsa AC miniature circuit breaker, tse sebediswang ditsamaisong tsa AC, disebediswa tsa DC miniature circuit breaker di etseditswe ho sebetsana le ditshebediso tsa DC. Phapang ena e bohlokwa hobane boitshwaro ba hona jwale tsamaisong ya DC bo fapane haholo le ba tsamaisong ya AC, haholoholo mabapi le ho thehwa ha arc le ho robeha ha potoloho.
Bohlokoa ba Li-DC Miniature Circuit Breakers
Bohlokoa ba li-DC miniature circuit breaker (MCBs) bo ke ke ba feteletsoa, haholo-holo lits'ebetsong tse kenyeletsang mehloli ea matla a nchafatsoang joalo ka liphanele tsa letsatsi le li-turbine tsa moea. Litsamaiso tsena hangata li hlahisa motlakase o tobileng, kahoo ho sebelisa li-DC miniature circuit breaker ho bohlokoa ho netefatsa polokeho le ts'epo. Li-DC miniature circuit breaker li fana ka tšireletso ea motlakase o feteletseng, e thusang ho thibela likotsi tse ka bang teng joalo ka mollo oa motlakase le tšenyo ea lisebelisoa, ka hona ho ntlafatsa polokeho ka kakaretso ea lits'ebetso tsa motlakase.
DC MCB e sebetsa joang?
Ts'ebetso ea DC miniature circuit breaker (MCB) e bonolo haholo. Ha motlakase o phallang ka har'a potoloho o feta moeli o reriloeng esale pele, mokhoa oa ka hare oa MCB oa qala. Mokhoa ona hangata o na le sekotwana sa bimetallic kapa khoele ea solenoid e arabelang motlakase o feteletseng. Hang ha o qala, MCB e bula potoloho, e khaola motlakase ka katleho le ho sireletsa lisebelisoa tse hokahantsoeng.
E 'ngoe ea likarolo tsa bohlokoa tsa DC miniature circuit breaker (MCB) ke bokhoni ba eona ba ho sitisa motlakase ntle le ho etsa li-arcs tse kotsi. Tsamaisong ea DC, motlakase ha o tšele lefela, e leng se ka fellang ka ho thekesela ha motlakase ka nako e telele haeba o sa laoloe hantle. Li-MCB tsa DC li entsoe ka likhokahano tse khethehileng le mekhoa ea ho fokotsa kotsi ea ho thekesela le ho netefatsa hore ho na le khaoho e sireletsehileng.
Tšebeliso ea Li-breaker tsa DC Miniature Circuit
Li-DC miniature circuit breaker li sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa:
1. Sistimi ea ho Hlahisa Matla a Letsatsi: Litsamaisong tsa photovoltaic, li-DC MCB li sireletsa lithapo le likarolo ho motlakase o feteletseng, e leng se netefatsang bophelo le polokeho ea ho kenya.
2. Likoloi tsa Motlakase: Ha indasteri ea likoloi e fetohela ho likoloi tsa motlakase, li-DC miniature circuit breaker li bapala karolo ea bohlokoa ho sireletseng litsamaiso tsa motlakase tsa likoloi hore li se ke tsa hloleha.
3. Mehala: Mekhoa e mengata ea puisano e sebetsa ka motlakase o tobileng, kahoo li-DC miniature circuit breaker lia hlokahala ho sireletsa lisebelisoa tse bonolo liphosong tsa motlakase.
4. Tšebeliso ea Liindasteri: Libakeng tse fapaneng tsa indasteri, li-DC miniature circuit breaker li sebelisoa ho sireletsa mechini le lisebelisoa tse tsamaisoang ke DC.
Khetha DC MCB e nepahetseng
Ha o kgetha DC miniature circuit breaker, ho lokela ho nahanelwa dintlha tse mmalwa:
- Motlakase o Lekantsoeng: Netefatsa hore motlakase o lekantsoeng oa MCB o lumellana le litlhoko tsa potoloho eo o lokelang ho e sireletsa.
- Voltage e lekantsoeng: Voltage e lekantsoeng ea MCB le eona e lokela ho lumellana le voltage ea sistimi ho netefatsa ts'ebetso e sireletsehileng.
- Bokgoni ba ho roba: E bolela bokgoni ba sethibela-potoloho se senyenyane (MCB) ba ho sitisa mothapo wa phoso. Bakeng sa ditsamaiso moo ho ka bang le maqhubu a mangata a phoso, bokgoni bo phahameng ba ho roba bo a hlokahala.
- Mofuta oa Mojaro: Mejaro e fapaneng (e hanyetsang, e susumetsang, jj.) e ka hloka mefuta e itseng ea li-MCB, kahoo ho utloisisa litšobotsi tsa mojaro ho bohlokoa.
Ka bokhutšoane
Ka bokhutšoanyane, li-DC miniature circuit breaker (MCBs) ke karolo ea bohlokoa ea litsamaiso tsa motlakase tsa sejoale-joale, haholo-holo lits'ebetsong tse kenyelletsang motlakase o tobileng. Bokhoni ba tsona ba ho fana ka tšireletso e tšepahalang ea motlakase o feteletseng bo bohlokoa ho netefatsa polokeho le katleho ea lisebelisoa tsa motlakase. Ha theknoloji e ntse e tsoela pele ho hatela pele, karolo ea li-DC miniature circuit breaker e ka 'na ea tsoela pele ho atoloha, e leng se tiisang bohlokoa ba tsona lefapheng la boenjiniere ba motlakase. Ho utloisisa mesebetsi ea tsona, lits'ebetso le litekanyetso tsa khetho ho bohlokoa ho mang kapa mang ea amehang moralong le tlhokomelong ea litsamaiso tsa motlakase.
