Sehlooho: Tseba Phapano Pakeng TsaLi-Circuit Breakers tse nyaneleMolded Case Circuit Breakers
Li-circuit breakers ke karolo ea bohlokoa ea sistimi ea motlakase ea moaho.Li thusa ho sireletsa ntlo ea hau, ofisi kapa thepa ea khoebo ho tsoa ho metlako ea motlakase le lipotoloho tse khutšoane.Li-circuit breaker tse peli tse atisang ho sebelisoa ke miniature circuit breaker (MCB) le sekhechana sa potoloho se bōpiloeng (MCCB).Le hoja ka bobeli li sebeletsa morero o le mong, ho na le phapang e itseng pakeng tsa tsona.Ka blog ena, re tla hlahloba liphapang tsena.
1. Boholo le tšebeliso
Phapang e ka sehloohong pakeng tsaMCBleMCCBke boholo ba tsona.Joalo ka ha lebitso le bontša, li-MCB li nyane ka boholo mme li sebelisoa lits'ebetsong tse tlase ho fihla ho 125 amps.Li sebelisoa hangata lits'ebetsong tsa bolulo le tse nyane tsa khoebo.Ka lehlakoreng le leng, li-MCCB li kholoanyane 'me li khona ho jara meroalo e phahameng ho fihlela ho 5000 amps.Hangata li sebelisoa lits'ebetsong tsa indasteri le tsa khoebo tse hlokang matla a phahameng.
2. E matla ebile e tšoarella
MCCB e matla ebile e tšoarella ho feta MCB.Li khona ho sebetsana le khatello ea motlakase e eketsehileng 'me li etselitsoe ho mamella maemo a thata.Li-MCCBshangata li entsoe ka thepa e matla joalo ka ceramic kapa polasetiki e bopehileng ho fetaLi-MCBs, tseo hangata li entsoeng ka ntlo ea polasetiki.Li-MCB li etselitsoe ho sebelisoa libakeng tse seng thata haholo 'me ha lia lokela ho pepesetsoa lintho tse senyang haholo kapa mocheso o feteletseng.
3. Mochine oa leeto
Ka bobeli li-MCB leLi-MCCBsli etselitsoe ho khoptjoa ha motlakase o feta moeli o itseng.Leha ho le joalo, mekhoa eo ba e sebelisang ho nka leeto e fapane.MCB e na le mochine oa leeto la mocheso oa makenete.Mochine ona o sebelisa mohala oa bimetal o futhumatsang le ho kobeha ha motlakase o feta monyako, e leng se etsang hore mohatelli oa potoloho a khopehe.MCCB e na le mochini oa maeto oa elektroniki o sebelisang microprocessor ho sekaseka phallo ea hajoale.Hang ha motlakase o feta monyako, microprocessor e romela letšoao ho mohatelli oa potoloho hore a tsamaee.
4. Litšenyehelo
Li-MCBshangata li theko e tlase ho fetaLi-MCCBs.Sena se bakoa ke hore li na le moralo o bonolo ebile li entsoe ka thepa e theko e tlaase.Hape ha li tšoarelle nako e telele ho feta li-MCCBs 'me li na le matla a tlaase a ho jara hona joale.Li-MCCB li theko e boima haholo ka lebaka la moralo oa tsona o rarahaneng le lisebelisoa tse sebelisoang, empa li tšoarella haholoanyane 'me li khona ho jara meroalo e phahameng ea hajoale.
5. Tlhokomelo
Tlhokomelo e hlokahalang bakeng sa MCBs leLi-MCCBse fapane haholo.MCB e bonolo ka moralo mme ha e hloke tlhokomelo e ngata.Li hloka ho hlahlojoa khafetsa ke ramotlakase le ho nkeloa sebaka haeba li na le phoso.Li-MCCB, ka lehlakoreng le leng, li hloka tlhokomelo e eketsehileng, joalo ka tlhahlobo ea kamehla ea likarolo tsa maeto tsa elektronike, tse ka 'nang tsa felloa ke nako ha nako e ntse e ea 'me li hloka ho nkeloa sebaka.
Ka kakaretso, MCB leMCCBe na le ts'ebetso e ts'oanang, e leng ho sireletsa tsamaiso ea motlakase ho tloha ho overload le potoloho e khutšoanyane.Leha ho le joalo, joalokaha re ka bona, ho na le ho se tšoane ho itseng pakeng tsa tse peli.Li-MCB li nyane, li tšoarella haholoanyane ebile li theko e tlase, ha li ntse liLi-MCCBsli matla, li tšoarella ebile li theko e boima.Kopo le litlhoko tsa hajoale ke lintlha tse ka sehloohong tse lokelang ho nahanoa ha u khetha pakeng tsa tse peli.
