Bohlokoa ba Li-DC Miniature Circuit Breakers
Bohlokoa ba li-DC miniature circuit breaker bo ke ke ba feteletsoa, haholo-holo lits'ebetsong moo matla a DC a atileng haholo. Lits'ebetso tsena li kenyelletsa litsamaiso tsa matla a nchafatsoang joalo ka ho kenngoa ha letsatsi la photovoltaic (PV), litsamaiso tsa polokelo ea matla a betri, le likoloi tsa motlakase. Maemong ana, ts'epo le polokeho ea sistimi ea motlakase ke tsa bohlokoa haholo, kahoo karolo ea li-DC miniature circuit breaker e bohlokoa haholo.
1. Tšireletso ea ho jara lintho tse ngata: Li-DC Miniature Circuit Breakers (MCBs) li sebelisoa ho sireletsa lipotoloho ho overloads. Ha motlakase o feta bokhoni bo lekantsoeng ba potoloho, MCB e tla khoptjoa, e kgaole mojaro le ho thibela tšenyo e ka bang teng mohala le lisebelisoa tse hokahaneng.
2. Tšireletso ea potoloho e khuts'oane: Ha potoloho e khuts'oane e hlaha, DC miniature circuit breaker (MCB) e ka lemoha phoso kapele 'me ea khaola motlakase. Karabelo ena e potlakileng e bohlokoa ho thibela tšenyo ea mollo le lisebelisoa.
3. Polokeho ea litsamaiso tsa eneji e nchafatsoang: Ka ho tuma ho ntseng ho eketseha ha litsamaiso tsa polokelo ea matla a letsatsi le a betri, li-DC miniature circuit breaker li bapala karolo ea bohlokoa ho netefatseng polokeho le katleho ea lits'ebetso tsena. Li thusa ho laola likotsi tse bakoang ke maqhubu a phahameng le li-voltage tse tloaelehileng litsamaisong tse joalo.
Molao-motheo oa ho Sebetsa oa DC Miniature Circuit Breaker
Molao-motheo oa ts'ebetso oa DC Miniature Circuit Breaker (MCB) ke motlakase le mocheso. Ha ho hlaha potoloho e feteletseng kapa e khutšoane, mokhoa oa ka hare oa MCB o lemoha hona joale ho feteletseng. Karolo ea mocheso e ikarabella bakeng sa ho feta tekano ha nako e telele, ha karolo ea motlakase e ikarabella bakeng sa potoloho e khuts'oane ea nakoana. Hang ha phoso e fumanoe, MCB e tla khoptjoa, e bule potoloho ebe e khaola hona joale.
Khetha DC MCB e nepahetseng
Ho khetha DC MCB e nepahetseng bakeng sa kopo e itseng ho hloka ho nahaneloa ka lintlha tse latelang:
- Motlakase o Lekantsoeng: Tekanyo ea hona joale ea Miniature Circuit Breaker (MCB) e tlameha ho khona ho sebetsana le motlakase o phahameng ka ho fetisisa o lebelletsoeng potolohong. Ho bohlokoa ho khetha sesebelisoa se ka sebetsanang le mojaro tlas'a maemo a tloaelehileng a ts'ebetso ntle le ho khoptjoa.
- Voltage e lekantsoeng: Etsa bonnete ba hore voltage e lekantsoeng ea MCB e tsamaellana le voltage e lekantsoeng ea sistimi ea DC. Ho sebelisa MCB e nang le voltage e lekantsoeng e tlase ho ka baka mathata le likotsi tsa polokeho.
- Bokgoni ba ho roba: Sena se bolela phokotso e phahameng ka ho fetisisa eo serobetsi sa potoloho e nyane se ka e sitisang ntle le ho senyeha. Ho bohlokwa haholo ho kgetha serobetsi sa potoloho e nyane se nang le bokgoni bo lekaneng ba ho roba.
- Mofuta oa Mojaro: Mejaro e fapaneng (e hanyetsang, e susumetsang kapa e nang le bokhoni) e ka hloka mefuta e fapaneng ea li-MCB. Ho utloisisa mofuta oa mojaro ho bohlokoa ho fihlela ts'ebetso e ntle ka ho fetisisa.
Ka bokhutšoane
Ka bokhutšoanyane, li-DC miniature circuit breaker (MCBs) ke karolo ea bohlokoa haholo litsamaisong tsa motlakase tsa sejoale-joale, haholo-holo lits'ebetsong tse kenyelletsang motlakase o tobileng. Li sireletsa khahlanong le ho jara ka bongata le lipotoloho tse khutšoane, li netefatsa polokeho le botšepehi ba lisebelisoa tsa motlakase. Ha theknoloji e ntse e tsoela pele ho fetoha, karolo ea li-DC miniature circuit breaker e tla ba ea bohlokoa haholo, kahoo litsebi lefapheng lena li tlameha ho utloisisa litšobotsi tsa tsona, melemo le litekanyetso tse loketseng tsa khetho. Ebang ke lefapheng la litsamaiso tsa matla a nchafatsoang kapa likoloi tsa motlakase, ho utloisisa li-DC miniature circuit breaker ho bohlokoa ho mang kapa mang ea amehang boenjiniere ba motlakase le kabo ea matla.
