KutloisisoLi-breaker tsa DC Miniature CircuitTataiso e Felletseng

Lefapheng la boenjiniere ba motlakase le polokeho, li-DC miniature circuit breaker (MCBs) li bapala karolo ea bohlokoa ho sireletseng lipotoloho tsa motlakase ho tsoa ho overload le lipotoloho tse khutšoane. Ha tlhoko ea litsamaiso tsa motlakase tse tšepahalang le tse sebetsang hantle e ntse e tsoela pele ho hola, ho utloisisa mesebetsi le ts'ebeliso ea li-DC miniature circuit breaker ho ba bohlokoa le ho feta.

Sehatsetsi sa potoloho se senyenyane sa DC ke eng?

Sesebediswa sa DC miniature circuit breaker (MCB) ke sesebediswa se sireletsang se kgaolang potoloho ka boiketsetso haeba ho na le ho jara boima ba motlakase kapa potoloho e kgutshwane. Ho fapana le disebediswa tsa AC circuit breaker, disebediswa tsa DC miniature circuit breaker di etseditswe ka ho kgetheha ho sebetsana le ditshebediso tsa direct current (DC). Phapang ena e bohlokwa hobane direct current e na le dibopeho tse fapaneng haholo le alternating current (AC), haholoholo mabapi le ho thehwa ha arc le ho robeha ha potoloho.

Likarolo tsa mantlha tsa li-DC miniature circuit breakers

1. Motlakase o Lekantsoeng: Li-DC miniature circuit breaker li na le mefuta e mengata ea maqhubu a lekantsoeng, hangata ho tloha ho li-ampere tse 'maloa ho isa ho li-ampere tse makholo. Sena se etsa hore ts'ebeliso ea tsona e tenyetsehe haholo 'me e khone ho ikamahanya le meroalo e fapaneng ea motlakase.

2. Tekanyetso ea Voltage: Li-circuit breaker tsena li etselitsoe ho sebetsa maemong a itseng a voltage, hangata ho fihlela ho 1000V DC. Ho bohlokoa ho khetha circuit breaker e lumellanang le litlhoko tsa voltage tsa circuit ea hau ho netefatsa ts'ebetso le polokeho e ntle ka ho fetisisa.

3. Mokhoa oa ho Tsamaea: Li-DC MCB li sebelisa mekhoa ea ho tsamaea ka mocheso le makenete ho lemoha ho jara ka bongata le lipotoloho tse khutšoane. Mokhoa oa ho tsamaea ka mocheso o sebetsana le ho jara ka bongata nako e telele, ha mokhoa oa ho tsamaea ka makenete o sebetsana le ho phahama ha motlakase ka tšohanyetso.

4. Moralo o mokgutshwane: E 'ngoe ea melemo ea bohlokoa ea li-DC miniature circuit breaker ke boholo ba tsona bo mokgutshwane, bo loketseng haholo bakeng sa ho kenya ka sebaka se fokolang. Moralo oa eona o e nolofalletsa ho kopanngoa habonolo le li-switchboard le litsamaiso tse fapaneng.

5. Maemo a polokeho: Li-DC miniature circuit breaker li etsoa ho latela maemo a machaba a polokeho ho netefatsa ts'epo le tšireletso ea lisebelisoa tsa motlakase. Hangata lisebelisoa tsena li latela mangolo a tumello a kang IEC 60947-2.

Tšebeliso ea li-breaker tsa potoloho tse nyane tsa DC

Li-DC miniature circuit breaker li sebelisoa lits'ebetsong tse fapaneng, ho kenyeletsoa:

- Mekhoa ea Matla a Nchafatsoang: Ka ho phahama ha lits'ebetso tsa letsatsi, li-DC miniature circuit breaker (MCB) li fetohile senotlolo sa ho sireletsa liphanele tsa letsatsi le li-inverter liphosong tse ka bang teng. Ha ho hlaha ntho e sa tloaelehang, li khaola potoloho ho netefatsa ts'ebetso e sireletsehileng ea sistimi ea photovoltaic.

- Likoloi tsa Motlakase (EV): Ha indasteri ea likoloi e ntse e fetohela likoloing tsa motlakase, li-DC miniature circuit breaker (MCB) li ntse li sebelisoa haholoanyane liteisheneng tsa ho tjhaja tsa EV. Li sireletsa potoloho ea ho tjhaja ho boima bo feteletseng, li netefatsa ts'ebetso ea ho tjhaja e bolokehileng le e sebetsang hantle.

- Mehala ea puisano: Meralong ea meralo ea puisano, li-DC MCB li sireletsa lisebelisoa tse bonolo ho tsoa ho matla a motlakase le liphoso, li boloka botšepehi ba litsamaiso tsa puisano.

- Ditshebediso tsa Diindasteri: Ditshebetso tse ngata tsa diindasteri di itshetlehile ka dienjene le disebediswa tsa DC, kahoo di-MCB tsa DC di bohlokwa ho sireletsa mechine le ho netefatsa tshebetso e bolokehileng.

Ka kakaretso

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 lipotoloho ho overload le lipotoloho tse khutšoane, ka hona li ntlafatsa polokeho le ts'epo mafapheng a fapaneng a kang matla a nchafatsoang, likoloi tsa motlakase, likhokahano tsa mohala le lits'ebetso tsa indasteri. Ha theknoloji e ntse e tsoela pele ho ntlafala, li-DC miniature circuit breaker li tla ba bohlokoa haholo, kahoo baenjiniere le litsebi tsa motlakase ba tlameha ho utloisisa litšobotsi tsa bona, lits'ebetso le melemo ea tsona. Ka ho kenyelletsa li-DC miniature circuit breaker meralong ea motlakase, litsebi li ka netefatsa hore litsamaiso tsa motlakase tsa nakong e tlang li bolokehile ebile li sebetsa hantle haholoanyane.
