Li-MCCB li reheletsoe ka moetso oa tsona o ikhethang, moo likarolo tsa sekhechana sa potoloho li kentsoeng ka har'a ntlo ea polasetiki e entsoeng ka botlolo. Ntlo ena e fana ka tšireletso e phahameng khahlanong le likotsi tsa tikoloho joalo ka lerōle, mongobo, le ho ama 'mele ka phoso, ho li etsa hore li tšoarelle nako e telele le tse tšepahalang bakeng sa maemo a fapaneng a ts'ebetso. Li-breaker tsena li tla ka boholo bo fapaneng, tse lumellang hore ho be le mefuta e mengata ea litekanyetso tsa hona joale le tsa voltage ho lumellana le lits'ebetso tse fapaneng.

Li-MCCB li ikhetha ka lebaka la tsonamoralo o kopaneng, boemo bo phahameng ba ho sitisa, letsepahala. Likarolo tsena li etsa hore e be tsa bohlokoa haholo bakeng sa ho sebelisoa maemong ao ho ona ho hlokahalang ts'ebetso e tsitsitseng le e bolokehileng ea lipotoloho tsa motlakase, ho tloha litsing tse nyane tsa bolulo ho isa ho marang-rang a maholo a indasteri.

Mesebetsi ea Bohlokoa ea li-MCCBs

Li-Circuit Breaker tsa Molded Case li sebetsa likarolo tse 'maloa tsa bohlokoa ho netefatsa polokeho le ts'ebetso ea lipotoloho tsa motlakase:

1. Tšireletso e Felletseng

Li-MCCB li na le ts'ireletso ea mocheso e arabelang maemo a mangata a tsitsitseng. Ha moroalo o mongata o etsahala, ho eketseha ha hona joale ho etsa hore karolo ea mocheso e futhumale. Ha mocheso o ntse o phahama, qetellong o baka mochine oa leeto, ho senya potoloho le ho thibela tšenyo e eketsehileng. Tšitiso ena ea othomathike e sireletsa lisebelisoa tsa motlakase le likhoele ho tsoa mochesong o feteletseng, e fokotsang kotsi ea mollo.

2. Tšireletso e Khutšoanyane ea Potoloho

Ha ho e-na le potoloho e khutšoanyane, moo phallo ea hona joale e fetang mojaro 'me e theha tsela e tobileng pakeng tsa mohloli oa matla le fatše, li-MCCB li sebelisa mochine oa maeto a khoheli. Mochine ona o sebetsa hang-hang, hangata ka har'a milliseconds, ho sitisa ho phalla ha hona joale. Karabelo e potlakileng ea MCCB e thibela tšenyo e kholo ea lisebelisoa le likhoele, ha e ntse e fokotsa kotsi ea mello ea motlakase.

3. Tšireletso ea Phoso ea fatše

Mathata a tlase a etsahala ha metsi a tsoa tseleng eo a e rerileng 'me a fumana tsela e eang fatše, e ka bakang likotsi kapa tšenyo ea lisebelisoa. Li-MCCB li khona ho bona liphoso tsa fatše, 'me hang-hang lia tsamaea ho ea arola phoso le ho sireletsa lisebelisoa le basebetsi kotsing.

4. Taolo ea Manual bakeng sa Tlhokomelo

Li-MCCB li boetse li etselitsoe ts'ebetso ea matsoho, e lumellang basebelisi hobula kapa koala ka letsohomoqhobi. Karolo ena e bohlokoa bakeng sa ho arola lipotoloho tsa motlakase nakong ea tlhokomelo, tlhahlobo, kapa ntlafatso ea sistimi, ho netefatsa polokeho ea basebetsi ba tlhokomelo ka ho thibela ho tsosolosoa ka phoso.

Ts'ebetso ea li-MCCBs

Ts'ebetso ea MCCB e ipapisitse le mekhoa e 'meli ea bohlokoa ea maeto:tšireletso ea mochesoletshireletso ya makenete.

Tšireletso ea Mocheso

Tšireletso ea mocheso e fanoa ka sekhahla sa bimetallic ka hare ho sehahi. Nakong ea ts'ebetso e tloaelehileng, sekhahla sa bimetallic se lula se pholile 'me sephahla se lula se koetsoe, se lumellang hona joale hore se phalle. Ha boima bo bongata bo etsahala, hona joale hoa eketseha, ho etsa hore sekhahla sa bimetallic se futhumale 'me se kobehe. Ho kobeha hona qetellong ho khopisa sekhechana, ho khaola phepelo ea motlakase. Tšireletso ea mocheso e loketse bakeng sa ho sireletsa khahlanong le lintho tse ngata tse ntseng li eketseha ha nako e ntse e ea, ho netefatsa hore motho ea senyang o arabela hantle ntle le ho sitisoa ho sa hlokahaleng.

Tšireletso ea Magnetic

Tšireletso ea makenete, ka lehlakoreng le leng, e etselitsoe ho arabela hang-hang ho li-circuits tse khutšoane. Koele e ka hare ho sekheo e etsa hore ho be le matla a khoheli ha potoloho e khuts'oane e etsahala, e leng se etsang hore plunger e khoephe seqhetso hang hang. Karabelo ena ea hang-hang e bohlokoa bakeng sa ho fokotsa tšenyo e bakiloeng ke li-circuits tse khutšoane, ho sireletsa lithapo le lisebelisoa tse hokahaneng.

Litlhophiso tsa Leeto tse Fetohang

Li-MCCB tse ngata li na le litlhophiso tsa maeto tse feto-fetohang, tse lumellang mosebelisi ho hlophisa hantle karabelo ea sekhechana ho meroalo e mengata le lipotoloho tse khutšoane. Mokhoa ona oa ho itloaetsa o nolofalletsa sekhechana hore se lokisoe ho latela litšobotsi tse ikhethang tsa sistimi ea motlakase, ho ntlafatsa ts'ireletso ntle le ho tela katleho ea ts'ebetso.

Mefuta ea li-MCCB

Li-MCCB li tla ka mefuta e fapaneng, li arotsoe ho latela litekanyetso tsa tsona tsa hajoale, litekanyetso tsa motlakase le litlhophiso tsa ts'ebetso. Mekhahlelo ea mantlha ke ena:

1. Thermal Magnetic MCCBs

Tsena ke mefuta e atileng haholo ea li-MCCB, tse nang le ts'ireletso ea mocheso le makenete. Li loketse mefuta e mengata ea likopo, ho tloha lits'ebetsong tse nyane tsa bolulo ho isa litsing tse kholo tsa indasteri. Ho feto-fetoha ha bona le katleho ho etsa hore e be khetho e ratoang bakeng sa tšireletso ea potoloho e akaretsang.

2. Leeto la Elektronike li-MCCBs

Li-MCCB tsa maeto a elektroniki, mochine oa maeto o laoloa ka mokhoa oa elektroniki, o fana ka litlhophiso tse nepahetseng haholoanyane tsa ts'ireletso. Hangata li-breaker tsena li tla le likarolo tse tsoetseng pele tse kang ho hlahloba nako ea sebele, tlhahlobo ea mafu, le bokhoni ba puisano, e leng se etsang hore e be tse loketseng bakeng sa lisebelisoa tse rarahaneng tsa motlakase libakeng tsa indasteri.

3. Li-MCCB tse setseng tsa Hona Joale

Li-MCCB tse setseng tsa hajoale li fana ka tšireletso khahlanong le liphoso tsa fatše le maqhubu a lutlang. Hangata li sebelisoa lits'ebetsong moo ho nang le kotsi ea ts'oaetso kapa moo ho lutla ha metsi ho tlamehang ho beoa leihlo ka hloko.

4. Li-MCCB tse fokotsang hona joale

Li-MCCB tsena li etselitsoe ho fokotsa lebelo la tlhōrō nakong ea potoloho e khutšoanyane, ho fokotsa matla a tsoang nakong ea phoso. Sena se fokotsa khatello ea mocheso le mochini tsamaisong ea motlakase, ho thusa ho thibela tšenyo ea lisebelisoa le lithapo.

Melemo ea Bohlokoa ea li-MCCB

Li-MCCB li ratoa lits'ebetsong tsa sejoale-joale tsa motlakase ka mabaka a 'maloa:

1. Bokhoni bo phahameng ba ho sitisa

Li-MCCB li khona ho sitisa maqhubu a maholo a phoso ntle le ho senya likarolo tsa tsona tse ka hare. Sena se etsa hore e be tse loketseng bakeng sa ho sebelisoa libakeng tseo ho tsona ho lebelletsoeng hore ho be le mathata a mangata, joalo ka maemo a indasteri le a khoebo.

2. Mekhahlelo e Pharalletseng ea Lintlha

Li-MCCB li fumaneha ka mefuta e mengata e fapaneng ea litekanyetso tsa hajoale le tsa motlakase, ho tloha tlase ho li-ampere tse 15 ho isa ho li-ampere tse fetang 2,500, le litekanyetso tsa motlakase ho fihla ho 1,000 volts. Sena se etsa hore li tšoanelehe bakeng sa mefuta e fapaneng ea likopo, ho tloha lits'ebetsong tse nyenyane tsa bolulo ho ea ho marang-rang a maholo a indasteri.

3. Moqapi oa Compact

Ho sa tsotellehe bokhoni ba tsona bo phahameng ba ho sitisa le kaho e matla, li-MCCB li batla li kopane. Moralo ona o kopaneng o lumella ho kengoa habonolo libakeng tse thata, ho fokotsa sebaka sa liphanele tsa motlakase le liboto tsa kabo.

4. Ho fetoha

Litlhophiso tsa maeto ho li-MCCB li ka fetoloa hore li tsamaellane le litlhoko tse ikhethileng tsa sistimi ea motlakase. Ho feto-fetoha ha maemo ho lumella basebelisi ho ntlafatsa ts'ebetso ea sekhechana bakeng sa lits'ebetso tse fapaneng, ho netefatsa ts'ireletso e phahameng ka ho fetisisa.

5. Tšireletseho le Tšireletso ea Tikoloho

Khalase e entsoeng ka polasetiki ea MCCB e fana ka tšireletso le tšireletso khahlanong le lerōle, mongobo le lintho tse ling tsa tikoloho. Sena se etsa hore li-MCCB li tšoarelle nako e telele 'me li lokele ho sebelisoa libakeng tse thata moo ho tšepahala ho leng bohlokoa.

Likopo tsa li-MCCBs

Li-MCCB li sebelisoa haholo lits'ebetsong tse fapaneng, ho kenyelletsa:

• Lisebelisoa tsa Indasteri:Libakeng tsa indasteri, li-MCCB li bohlokoa bakeng sa ho sireletsa mechini, lienjineri le lits'ebetso tsa phepelo ea motlakase tšenyo e bakiloeng ke liphoso.
• Mehaho ea Khoebo:Li-MCCB li netefatsa polokeho ea lipotoloho tsa motlakase meahong ea khoebo, li sireletsa khahlanong le liphoso tse ka sitisang ts'ebetso kapa tsa beha likotsi tsa polokeho ho baahi.
• Thepa ea Bolulo:Le hoja li-circuit breakers tse nyenyane li atisa ho sebelisoa libakeng tsa bolulo, li-MCCB li sebelisoa malapeng a maholoanyane le libakeng tsa bolulo tse ngata moo ho hlokahalang litekanyetso tse phahameng tsa hona joale le matla a mangata a sitisang.
• Sistimi ea Matla a Tsosolositsoeng:Li-MCCB li sebelisoa hangata lits'ebetsong tsa matla a ka nchafatsoang, joalo ka lits'ebetso tsa letsatsi le moea, ho sireletsa lipotoloho tsa motlakase liphosong tse ka senyang thepa kapa tsa sitisa phepelo ea motlakase.
