Phapang ena e bohlokwa hobane boitshwaro ba hajwale ditsamaisong tsa DC bo fapane haholo le ba ditsamaisong tsa AC, haholoholo mabapi le ho fela ha arc le dibopeho tsa hona jwale tsa phoso.
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, e leng se etsang hore karolo ea li-DC miniature circuit breaker e be ea bohlokoa.
1. Tšireletso ea ho Feta Moroalo: Li-DC miniature circuit breaker (MCB) li sebelisoa ho sireletsa lipotoloho ho overloads. Ha motlakase o feta bokhoni ba potoloho bo lekantsoeng, MCB ea thella, e thibela tšenyo ea lithapo le lisebelisoa tse hokahaneng.
2. Tšireletso ea potoloho e khuts'oane: Ha potoloho e khuts'oane e hlaha, li-DC miniature circuit breakers (MCBs) li khaola potoloho kapele, li fokotsa kotsi ea mollo le tšenyo ea lisebelisoa. Karabelo ena e potlakileng e bohlokoa ho boloka polokeho ea sistimi ea motlakase.
3. Moralo o loketseng ho sebelisoa: Bongata ba li-DC miniature circuit breaker li etselitsoe ho ba bonolo ho li kenya le ho li sebelisa. Hangata li na le switch e bonolo ea ho fetola li-toggle bakeng sa ho li seta bocha ka letsoho kamora ho khoptjoa, e leng se etsang hore li be bonolo bakeng sa litsebi le barati ba DIY ho li sebelisa.
Likarolo tsa mantlha tsa li-DC miniature circuit breakers
Ha o kgetha DC miniature circuit breaker, ho lokela ho nahanelwa ka dikarolo tse mmalwa tsa bohlokwa:
Lekanyeditswe Motlakase: Di-DC miniature circuit breaker (MCB) di fumaneha ka mefuta e fapaneng ya maqhubu a lekanyeditsweng, e leng se dumellang basebedisi ho kgetha sesebediswa se loketseng ho latela ditlhoko tsa bona tse ikgethang tsa tshebediso. Ho kgetha se-miniature circuit breaker se loketseng sa motlakase wa ...
- Voltage e Lekantsoeng: Voltage e lekantsoeng ea DC MCB e bontša voltage e phahameng ka ho fetisisa eo e ka e mamellang. Ho bohlokoa ho khetha MCB e lumellanang le voltage ea sistimi ho qoba ho se sebetse hantle.
- Litšobotsi tsa Leeto: Li-miniature breaker tse fapaneng li na le litšobotsi tse fapaneng tsa leeto, tse khethollang hore na li arabela kapele hakae ho overload le lipotoloho tse khutšoane. Ho utloisisa litšobotsi tsena ho bohlokoa ho netefatsa polokeho le botšepehi ba litsamaiso tsa motlakase.
- Tlhophiso ea Lipalo: Li-MCB tsa DC li fumaneha ka litlhophiso tsa palo e le 'ngoe, palo e habeli, le palo e ngata, ho latela palo ea lipotoloho tseo li hlokang ho li sireletsa. Khetho ea tlhophiso e itšetlehile ka ts'ebeliso e itseng le moralo oa sistimi.
Tšebeliso ea Li-breaker tsa DC Miniature Circuit
Li-DC miniature circuit breaker li na le mefuta e mengata ea ts'ebeliso, ho kenyeletsoa:
- Sistimi ea Tlhahiso ea Matla a Letsatsi: Lits'ebetsong tsa photovoltaic tsa letsatsi, li-DC MCB li sireletsa lithapo le likarolo ho overload le lipotoloho tse khutšoane, ho netefatsa polokeho le katleho ea sistimi.
- Mekhoa ea ho Boloka Libetri: Ha malapa le likhoebo tse ngata li ntse li amohela litharollo tsa ho boloka libetri, li-DC MCB li bapala karolo ea bohlokoa ho sireletseng litsamaiso tsena liphosong tsa motlakase.
- Likoloi tsa Motlakase: Likoloing tsa motlakase, li-DC MCB li bohlokoa bakeng sa ho sireletsa libeteri le litsamaiso tsa motlakase, li thusa ho netefatsa polokeho ka kakaretso ea koloi.
Ka bokhutšoane
Ha re bua ka bokhutšoanyane, li-DC miniature circuit breaker (MCB) ke likarolo tsa bohlokoa lits'ebetsong tsa motlakase tsa DC tsa sejoale-joale. Bokhoni ba tsona ba ho sireletsa motlakase o feteletseng le oa potoloho e khuts'oane bo etsa hore li be bohlokoa haholo lits'ebetsong ho tloha ho matla a nchafatsoang ho isa likoloing tsa motlakase. Ha theknoloji e ntse e tsoela pele ho hatela pele, ho utloisisa le ho sebelisa li-DC miniature circuit breaker ho tla ba bohlokoa haholo ho netefatsa polokeho le ts'epo ea litsamaiso tsa motlakase lefatšeng le ntseng le eketseha ka motlakase.
