A molded case circuit breaker (MCCB)ke mofuta oa sekheo sa potoloho se sebelisoang haholo bakeng sa ts'ireletso ea motlakase litsing tsa indasteri le tsa khoebo ka lebaka la bokhoni ba eona ba ho fana ka ts'ireletso e ts'epahalang le e bolokehileng khahlano le overcurrent, lipotoloho tse khutšoane le mefokolo e meng ea motlakase.Sehloohong sena, re tla hlahloba ka boteboLi-MCCBsle ho buisana ka litšobotsi tsa bona, melao-motheo ea ts'ebetso, kaho le ts'ebeliso.
Litšobotsi tsa MCCBs
Li-MCCB li entsoe ka mesebetsi e mengata e thusang ho sireletsa lisebelisoa tsa motlakase ka mokhoa o sireletsehileng le o ka tšeptjoang.Lintlha tse ling tsa bohlokoa tsa MCCB li kenyelletsa:
- Matla a phahameng a ho robeha:Molded case circuit breakersli khona ho pshatla maqhubu ho fihla ho li-ampere tse likete, e leng se etsang hore e be tse loketseng bakeng sa lisebelisoa tsa matla a phahameng.
- Thermal-magnetic trip mechanism:Molded case circuit breakerssebelisa mochine oa leeto la thermal-magnetic ho bona le ho arabela lipotolohong tse fetang nako e telele le tse khutšoane.Likarolo tsa maeto a mocheso li arabela meroalo e mengata, ha likarolo tsa maeto a makenete li arabela lipotolohong tse khutšoane.
- Litlhophiso tsa Maeto tse Fetohang: Li-MCCB li na le litlhophiso tsa maeto tse feto-fetohang, tse li lumellang hore li be boemong bo loketseng bakeng sa ts'ebeliso e lakatsehang.
- Mefuta e mengata ea boholo ba foreimi: li-MCCB li fumaneha ka mefuta e sa tšoaneng ea liforeimi, tse li lumellang hore li sebelisoe mefuteng e sa tšoaneng. .Thermal trip element e utloa mocheso o hlahisoang ke ho phalla ha hona joale potolohong 'me e hula sekhechana sa potoloho ha motlakase o feta tekanyo ea leeto.The magnetic trip element e utloa matla a khoheli a hlahisoang ke potoloho e khuts'oane ea potoloho, e khopa sekhechana hang hang. Sebopeho sa molded case circuit breaker.
- MCCB e na le ntlo ea polasetiki e entsoeng e nang le mochini oa maeto, likhokahano le likarolo tsa hona joale tsa thepa.
- Likhokahano li entsoe ka thepa e tsamaisang haholo joalo ka koporo, ha mochini oa leeto o na le khoele ea bimetallic le khoele ea makenete.
Tšebeliso ea MCCB
Li-MCCB li sebelisoa hangata lits'ebetsong tse fapaneng tse kang:
- Sistimi ea kabo ea matla
- Setsi sa Taolo ea Likoloi
- Mechini ea indasteri
- Li-transformer
- Sete ea jenereithara
ha re phethela
Li-case circuit breaker ke lisebelisoa tse tšepahalang haholo le tse sebetsang hantle bakeng sa ts'ireletso ea motlakase.Kaho ea bona le litšoaneleho tsa bona li li etsa hore e be tse loketseng ho sebelisoa lits'ebetsong tse fapaneng tse kang li-transformer, litsamaiso tsa kabo ea motlakase le litsi tsa taolo ea makoloi.Mochine oa bona oa maeto a mocheso oa motlakase, bokhoni bo phahameng ba ho pshatla le litlhophiso tsa maeto tse feto-fetohang li ba etsa khetho e tsebahalang bakeng sa ts'ireletso ea motlakase litsing tsa khoebo le tsa indasteri.
