Bohlokoa le ts'ebetso ea li-circuit breakers tse nyane

Sehlooho: Bohlokoa le mosebetsi oali-circuits tse nyane

tsebisa:

Li-circuit breakers (MCBs)bapala karolo ea bohlokoa ho netefatsa polokeho le ts'epahalo ea lits'ebetso tsa motlakase.Lisebelisoa tsena li fetohile karolo ea bohlokoa ea lisebelisoa tsa morao-rao tsa motlakase, tse sebelisetsoang ho thibela mefokolo ea motlakase le ho fokotsa tšenyo e ka bang teng.Sengoliloeng sena se hlahloba bohlokoa le ts'ebetso ea balebeli bana ba compact, ho bonts'a bohlokoa ba bona lefapheng la boenjiniere ba motlakase.

1. Utloisisa li-circuit breakers:

A sekhechana sa potoloho e nyane, hangata e khutsufatsoa joalo kaMCB, ke sesebelisoa sa motlakase se ikemetseng se etselitsoeng ho sireletsa lipotoloho tsa motlakase ho li-circuits tse fetelletseng le tse khutšoane.Hangata lisebelisoa tsena li kenngoa ka li-switchboards, lisebelisoa tsa bareki le mabokose a fuse e le mokhoa oa pele oa tšireletso khahlanong le ho hlōleha ha motlakase.

2. Likarolo tsa mantlha le likarolo:

Li-MCBsli tsebahala ka boholo ba tsona bo kopaneng, hangata li lula sebakeng se le seng sa modular ka har'a switchboard.Leha ho le joalo, boholo ba tsona bo nyane bo hanana le bohlokoa ba tsona ho boloka polokeho ea motlakase.Likarolo tse kholo tsaMCBkenyelletsa mochine oa ho fetola, mabitso le mochine oa maeto.

Mochine oa switjha o lumella ts'ebetso ea letsoho, e nolofalletsang mosebelisi ho bula kapa ho koala potoloho ka letsoho.Mabitso, ka lehlakoreng le leng, a na le boikarabello ba ho tsamaisa le ho sitisa hona joale ho phalla ho potoloha potoloho.Qetellong, mochine oa leeto o lemoha potoloho e feteletseng kapa e khutšoanyane 'me e etsa hore ho be leMCBho bula potoloho, ka hona ho sireletsa tsamaiso.

3. Tšireletso e fetelletseng:

E 'ngoe ea mesebetsi ea mantlha eaMCBke ho thibela overcurrent.Overcurrent e etsahala ha ho feta hona joale ho phalla ka potoloho ho feta matla a eona a lekantsoeng, e leng se ka lebisang ho chesa le ho senya likarolo tsa motlakase.Li-MCBsarabela boemo bona ka ho sitisa hang-hang potoloho ea motlakase, kahoo ho thibela ho chesa le ho fokotsa kotsi ea mollo oa motlakase.

4. Tšireletso ea potoloho e khutšoanyane:

Karolo e 'ngoe ea bohlokoa eaMCBke ho thibela potoloho e khutšoane.Potoloho e khuts'oane e etsahala ha khokahano e sa lebelloang (hangata ka lebaka la ho se sebetse hantle kapa ho hloleha ha insulation) e etsa hore hona joale ho phalle ho potoloha potolohong.Potoloho e khuts'oane e ka baka tšenyo e kholo ho sesebelisoa mme e ka ba ea baka mollo.Nako ea karabelo e potlakileng ea MCB e e nolofalletsa ho lemoha lipotoloho tse khutšoane le ho sitisa potoloho pele ho ts'enyehelo e kholo.

5. Phapang le fuse:

Le ha li-MCB le li-fuse ka bobeli li fana ka tšireletso khahlanong le liphoso tsa motlakase, ho na le phapang e kholo lipakeng tsa tse peli.Li-fuse li na le lithapo tse tšesaane kapa likotoana tsa tšepe tse qhibilihang ha metsi a phalla haholo, a senya potoloho.Hang ha fuse e lla, e hloka ho nkeloa sebaka.Ka lehlakoreng le leng, li-MCB ha li hloke ho nkeloa sebaka ka mor'a ho khoptjoa.Ho e-na le hoo, li ka tsosolosoa habonolo ka mor'a hore ho hlahlojoe ho hlōleha ha motso le ho rarolloa, ho etsa hore ho be bonolo le ho boloka chelete e ngata ha nako e ntse e ea.

6. Khetho le Khethollo:

Litsamaisong tse rarahaneng tsa motlakase moo li ngataLi-MCBsli kentsoe letotong, mehopolo ea khetho le khethollo e ba ea bohlokoa.Selectivity e bolela bokhoni ba MCB ba ho arola potoloho e fosahetseng ntle le ho senya tsamaiso eohle.Phapang, ka lehlakoreng le leng, e tiisa hore MCB e haufi le phoso e tsamaea pele, kahoo e fokotsa litšitiso ho kenyeng.Litšobotsi tsena li lumella karabelo e lebisitsoeng ho ho hloleha ha motlakase, ho netefatsa ho tsoela pele ha lits'ebeletso tsa bohlokoa ha ho ntse ho fumanoa le ho rarolla sesosa sa ho hloleha.

ha re phethela:

Li-circuit breakers tse nyaneha ho pelaelo hore ke karolo ea bohlokoa ea lisebelisoa tsa morao-rao tsa motlakase.Ka ho fana ka tšireletso ea potoloho e fetelletseng le e khuts'oane, li-MCB li thusa ho sireletsa lisebelisoa, ho fokotsa tšenyo le ho thibela mollo oa motlakase.Boholo ba tsona bo kopaneng, bonolo ba ts'ebeliso, le bokhoni ba ho seta bocha kamora leeto li li etsa khetho e ntle ho feta li-fuse tsa setso.Ho bohlokoa ho hopola hore ho kenya ts'ebetso e nepahetseng le tlhokomelo ea kamehla ea li-MCB ho bohlokoa bakeng sa sistimi e sebetsang hantle le e tšepahalang ea motlakase.Ka ho utloisisa hantle le ho sebelisa li-circuit breaker tse nyane, re ka ntlafatsa polokeho le ts'ebetso e felletseng ea lisebelisoa tsa motlakase.
