Miniature Circuit Breaker JCB3 63DC1000V DC: Tšireletso e Tšepahalang bakeng sa DC Power Systems

Lefatšeng la kajeno, matla a DC (Direct Current) a sebelisoa haholo lits'ebetsong tsa matla a letsatsi, polokelo ea betri, ho tjhaja koloi ea motlakase (EV), likhokahano tsa mehala le lits'ebetso tsa indasteri. Ha liindasteri le beng ba matlo ba ntse ba fetohela ho litharollo tsa matla a tsosolositsoeng, tlhoko ea ts'ireletso ea potoloho e tšepahalang ha e so ka e ba kholo ho feta.

 

TheJCB3-63DC1000V DC Miniature Circuit Breaker (MCB)ke sesebelisoa sa ts'ireletso se sebetsang hantle haholo se etselitsoeng lisebelisoa tsa motlakase tsa DC. Ka bokhoni ba eona bo phahameng ba ho robeha (6kA), moralo o se nang polarized, tlhophiso ea lipalo tse ngata, le ho latela litekanyetso tsa polokeho ea IEC, e netefatsa polokeho le ts'ebetso e nepahetseng.

 

Tataiso ena e tla hlahloba bohlokoa ba ts'ireletso ea potoloho ea DC, likarolo tsa bohlokoa, lits'ebetso, melemo, tataiso ea ho kenya, malebela a tlhokomelo, le papiso le li-MCB tse ling.

 

Ke Hobane'ng ha Tšireletso ea Potoloho ea DC e le Bohlokoa

 

Sistimi ea motlakase ea DC e sebelisoa haholo lits'ebetsong tsa solar photovoltaic (PV), litharollo tsa matla tsa backup, likoloi tsa motlakase le li-automation tsa indasteri. Leha ho le joalo, liphoso tsa DC li kotsi ho feta liphoso tsa AC hobane li-arc tsa DC li thata ho tima.

Haeba potoloho e khuts'oane kapa boima bo feteletseng bo etsahala, bo ka lebisa ho:

 

✔ Tšenyo ea lisebelisoa - Ho futhumala ho feteletseng le ho phahama ha matla ho ka khutsufatsa nako ea bophelo ea likarolo tse turang.

✔ Likotsi tsa mollo - Maqhubu a sa khaotseng a DC a ka boloka li-arcs tsa motlakase, a eketsa kotsi ea mollo.

✔ Ho hloleha ha Sisteme - Sistimi e sa sireletsoang e ka lahleheloa ke matla ka ho felletseng, e bakang nako ea ho theoha le ho lokisoa ho theko e boima.

 

Sesebelisoa sa boleng bo holimo sa potoloho ea DC, joalo ka JCB3-63DC, se bohlokoa bakeng sa ho netefatsa polokeho, ho thibela tšenyo e theko e boima, le ho boloka phallo ea matla e sa sitisoeng.
