KutloisisoRCCBKarolo ea Bohlokoa bakeng sa Polokeho ea Motlakase
Lefatšeng la polokeho ea motlakase, li-residual current circuit breaker (RCCBs) ke lisebelisoa tsa bohlokoa tse sireletsang batho le thepa likotsing tsa liphoso tsa motlakase. Ha u teba ho rarahaneng ha li-RCCB, ho bohlokoa ho utloisisa mosebetsi oa tsona, bohlokoa le morero oa tsona litsamaisong tsa motlakase tsa sejoale-joale.
RCCB ke eng?
Sehatsetsi sa potoloho sa motlakase se setseng (RCCB), se tsejoang hape e le sesebelisoa sa motlakase se setseng (RCD), ke sesebelisoa sa motlakase se kgaolang potoloho ea motlakase ha se lemoha ho se leka-lekane ha motlakase pakeng tsa lithapo tse phelang le tse sa nke lehlakore. Ho se leka-lekane hona ho ka bakoa ke mabaka a 'maloa, joalo ka terata e fosahetseng, ho hloleha ha ho kenya mocheso, kapa ho kopana ka phoso le terata e phelang. RCCB e lula e beha leihlo motlakase o phallang potolohong 'me e ka lemoha le liphapang tse nyane, hangata tse tlase ho 30 milliamps (mA). Ha ho se leka-lekane ho fumanoa, e kgaola phepelo ea motlakase kapele, ka hona e thibela ho tšoha ha motlakase le ho fokotsa kotsi ea mollo oa motlakase.
Bohlokoa ba RCCB
Bohlokoa ba li-RCCB polokehong ea motlakase bo ke ke ba feteletsoa. Mehaho e mengata ea bolulo le ea khoebo e hlokahala ho kenya li-RCCB ho latela maemo le melawana e fapaneng ea polokeho. Sesebelisoa ke mohala oa pele oa tšireletso khahlanong le likotsi tsa motlakase 'me se ka fokotsa kotsi ea ho tšoha ha motlakase le mollo o bakoang ke liphoso tsa motlakase haholo.
Ntle le ho sireletsa basebetsi, li-RCCB li boetse li sireletsa lisebelisoa tsa motlakase le litsamaiso. Li-RCCB li sireletsa khahlanong le ho imeloa haholo le lipotoloho tse khutšoane, li thusa ho boloka botšepehi ba lisebelisoa tsa motlakase, ka hona li lelefatsa bophelo ba lisebelisoa le ho fokotsa litšenyehelo tsa tlhokomelo.
Molao-motheo oa ts'ebetso oa RCCB
RCCB e sebetsa ka ho lemoha phapang pakeng tsa lithapo tse chesang le tse sa nke lehlakore. Ka tloaelo, motlakase o kenang potolohong ka terata e chesang o lokela ho lekana le motlakase o khutlang ka terata e sa nke lehlakore. Haeba ho hlaha phoso, joalo ka motlakase o lutlang o phallelang fatše, RCCB e lemoha ho se leka-lekane hona.
Hang ha RCCB e lemoha ntho e sa tloaelehang, e qala mokhoa o kgaolang potoloho ka hara di-millisecond. Karabelo ena e potlakileng e bohlokwa ho thibela kotsi e mpe kapa esita le lefu le bakwang ke ho tshoha ha motlakase.
Mefuta ea RCCB
Ho na le mefuta e 'maloa ea li-RCCB, e 'ngoe le e 'ngoe e na le morero o itseng. Mefuta e tloaelehileng haholo e kenyelletsa:
1. Bipolar RCCB: E sebediswa bakeng sa dipotoloho tsa mohato o le mong mme hangata e sebediswa dibakeng tsa bodulo.
2. RCCB ea lipalo tse 'ne: E etselitsoe lipotoloho tsa mekhahlelo e meraro, tse sebelisoang haholo lits'ebetsong tsa indasteri le tsa khoebo.
3. RCCB e Kopantsweng le MCB**: Disebediswa tse ding di kopanya mesebetsi ya RCCB le Miniature Circuit Breaker (MCB) ho fana ka tshireletso ya hona jwale e setseng le tshireletso ya overload yuniti e le nngwe.
Ho kenya le ho hlokomela
Ho kenya le ho hlokomela kamehla li-residual current circuit breaker (RCCBs) ho bohlokoa ho netefatsa hore li sebetsa hantle. Ho khothaletsoa hore li kenngoe ke setsebi sa motlakase se tšoanelehang ho latela melao le maemo a motlakase a lehae. Ho phaella moo, li-residual current circuit breaker li lokela ho lekoa khafetsa ho sebelisoa konopo ea teko e fanoeng sesebelisoa ho netefatsa hore li sebetsa hantle.
Ka bokhutšoane
Ka bokhutšoanyane, li-residual current circuit breaker (RCCBs) ke karolo ea bohlokoa ea litsamaiso tsa motlakase tsa sejoale-joale, tse fanang ka tšireletso ea bohlokoa ea motlakase. Ke lisebelisoa tsa bohlokoa tse sireletsang bophelo le thepa ka ho lemoha ho se leka-lekane ha hona joale le ho khaola lipotoloho ka potlako. Ha maemo a polokeho ea motlakase a ntse a tsoela pele ho fetoha, li-RCCB li tla tsoela pele ho bapala karolo ea bohlokoa ho netefatseng hore lisebelisoa tsa motlakase li bolokehile ebile lia tšepahala. Ebang ke lapeng, ofising, kapa indastering, ho utloisisa le ho sebelisa li-RCCB ke mohato oa bohlokoa ho ea tikolohong e sireletsehileng ea motlakase.
