Sekhechana sa potoloho se senyenyane (MCB) ke eng?

ASekhahla se Senyenyane sa Potoloho (MCB)ke sesebelisoa sa motlakase se sebetsang ka boiketsetso se etselitsoeng ho sireletsa lipotoloho tsa motlakase ts'enyong e bakiloeng ke overcurrent, short circuits, or overloads. Ke karolo ea bohlokoa lits'ebetsong tsa sejoale-joale tsa motlakase, tse sebelisoang hangata lits'ebetsong tsa bolulo, tsa khoebo le tsa indasteri ho netefatsa polokeho le ho thibela mello ea motlakase.

Lintlha tsa bohlokoa tsa MCB:

1. Tšireletso ea Overcurrent:

   • E lemoha phallo e feteletseng ea hona joale mme e sitisa potoloho ho thibela tšenyo ea lithapo le lisebelisoa.

2. Tšireletso e Khutšoanyane ea Potoloho:

   • Ka potlako e khaola potoloho ha ho e-na le potoloho e khutšoanyane, ho fokotsa kotsi ea mollo kapa tšenyo ea thepa.

3. Tšireletso e Felletseng:

   • E sireletsa khahlanong le overloading ea nako e telele ea potoloho, e ka bakang ho chesa haholo.

4. Ho fetola ka letsoho:

   • E ka sebetsoa ka letsoho ho bulela kapa ho tima potoloho, e sebetsa e le switch bakeng sa tlhokomelo kapa maemo a tšohanyetso.

5. E ka hlophisoa bocha:

   • Ho fapana le fuse, e hlokang ho nkeloa sebaka ka mor'a ho khoptjoa, MCB e ka tsosolosoa habonolo le ho sebelisoa hape.

6. Moqapi oa Compact:

   • E nyane ebile e bobebe, e etsa hore ho be bonolo ho kenya libotong tsa kabo ea motlakase.

7. Boemo ba Hona Joale:

   • E fumaneha ka lintlha tse fapaneng tsa hajoale (mohlala, 1A, 2A, 3A, 4A, 5A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A, 100A, 125A, lisebelisoa tse fapaneng).

8. Litšobotsi Tsa Leeto:

   • Li-MCB li arotsoe ho ipapisitsoe le li-curve curves (mohlala, B, C, D) ho tsamaisana le mefuta e itseng ea mojaro:

     • Mofuta oa B: E loketse bakeng sa likopo tsa bolulo (tse utloahalang ho li-overcurrents tse nyenyane).

     • Mofuta oa C: E loketse lits'ebetso tsa khoebo le tsa indasteri (e sebetsana le maqhubu a inrush a itekanetseng).

     • Mofuta oa D: E sebelisoa bakeng sa meroalo e boima ea indasteri e nang le maqhubu a phahameng a inrush (mohlala, li-motor, li-transformer).

Kamoo MCB e Sebetsang kateng:

• Tlas'a maemo a tloaelehileng, MCB e lumella hona joale ho phalla ho potoloha potoloho.

• Ha ho fetella, potoloho e khuts'oane, kapa moroalo o mongata, mochini o ka hare (mocheso kapa makenete) o hula sekhechana, o hakolla potoloho.

• Hang ha phoso e rarollotsoe, MCB e ka tsosolosoa ho tsosolosa matla.

Lisebelisoa:

• Mehaho ea bolulo: Li-MCB li sebelisoa haholo malapeng ho sireletsa mabone, li-sockets le lisebelisoa (mohlala, li-circuits tsa mabone, li-socket, lisebelisoa tsa kichineng, li-air conditioner, li-heaters tsa metsi, joalo-joalo). Melemo: Tšireletseho e ntlafetseng, tšireletso e khethehileng, le ts'ebetso e bonolo ho basebelisi.

• Libaka tsa khoebo: Liofising, mabenkeleng le libakeng tse ling tsa khoebo, li-MCB li sireletsa lisebelisoa le lisebelisoa tsa motlakase (mohlala, lisebelisoa tsa mabone, li-sockets tsa motlakase, lisebelisoa tsa HVAC, lisebelisoa tsa IT, joalo-joalo). Melemo: Tšireletso e ka tšeptjoang bakeng sa lisebelisoa tse hlokolosi le ho fokotsa nako e fokolang nakong ea liphoso.

• Lisebelisoa tsa indasteri: Li-MCB li sebelisoa maemong a indasteri ho sireletsa mechini e boima, li-motor le litsamaiso tsa taolo (mohlala, li-circuits tsa makoloi, liphanele tsa taolo, mochini, liboto tsa kabo, jj.). Melemo: Ho tšoarella ha nako e telele, ho lemoha liphoso ka nepo, le tšireletso khahlanong le maqhubu a matla a ho hlasela.

• Litsamaiso tsa matla a tsosolositsoeng: Li-MCB li sebelisoa lits'ebetsong tsa matla a letsatsi le lits'ebetsong tse ling tse nchafalitsoeng (mohlala, li-inverters tsa letsatsi, lits'ebetso tsa polokelo ea betri, liphanele tsa kabo, joalo-joalo). Melemo: E netefatsa ts'ebetso e bolokehileng ea lisebelisoa tsa matla a tsosolositsoeng le ho sireletsa khahlanong le li-overcurrents.

• Libaka tse ka ntle le tse thata: Li-MCB tse etselitsoeng tikoloho ea kantle kapa e thata li sebelisoa libakeng tsa kaho, lits'ebetsong tsa metsing, le libakeng tsa temo (mohlala, libaka tsa kaho, lisebelisoa tsa temo, lits'ebetso tsa metsing, joalo-joalo). Melemo: Tšireletso e tšoarellang le e tšepahalang maemong a thata.

Qetello:

MCB ke sesebelisoa sa bohlokoa sa polokeho lits'ebetsong tsa motlakase, se fanang ka ts'ireletso e ts'epahalang khahlanong le liphoso tsa motlakase ha ho ntse ho le bonolo ho se sebelisa le ho se hlokomela.
