KutloisisoLi-MCBleLi-RCCBLikarolo tsa Bohlokoa tsa Polokeho ea Motlakase
Polokeho ke ea bohlokoa haholo lefatšeng la lits'ebetso tsa motlakase. Li-miniature circuit breaker (MCBs) le li-residual current circuit breaker (RCCBs) ke likarolo tse peli tsa bohlokoa bakeng sa ho netefatsa polokeho ea motlakase. Lisebelisoa tsena tse peli li na le ts'ebeliso e fapaneng empa hangata li sebelisoa hammoho ho fana ka tšireletso e felletseng khahlanong le liphoso tsa motlakase. Sengoloa sena se sheba ka botebo mesebetsi, liphapang, le ts'ebeliso ea li-miniature circuit breaker (MCBs) le li-residual current circuit breaker (RCCBs), 'me se totobatsa bohlokoa ba tsona litsamaisong tsa motlakase tsa sejoale-joale.
MCB ke eng?
Sehahi sa potoloho se senyenyane (MCB) ke switch e iketsang e sebediswang ho sireletsa dipotoloho tsa motlakase ho di-overload le dipotoloho tse kgutshwane. Ha motlakase o phallang ka hara potoloho o feta moedi o rerilweng esale pele, MCB e a kgopa le ho kgaola phepelo ya motlakase. Sena se thibela ho chesa haholo le dikotsi tse ka bang teng tsa mollo tse bakwang ke motlakase o feteletseng. Mocheso o lekantsweng wa MCB o itshetlehile ka bokgoni ba wona ba ho jara motlakase, hangata pakeng tsa 6A le 63A, mme o reretswe ho sebetsa kapele ho fokotsa tshenyo disebedisweng le dithapong.
Li-circuit breaker tse nyane (li-MCB)li bohlokoa libakeng tsa bolulo, tsa khoebo le tsa indasteri. Hangata li sebelisoa li-switchboard ho sireletsa lipotoloho ka bonngoe, ho netefatsa hore ho hloleha ha potoloho e le 'ngoe ha ho ame sistimi eohle ea motlakase. Li-miniature circuit breaker li ka setafatsoa, kahoo motlakase o ka tsosolosoa habonolo kamora hore phoso e lokisoe, e leng se etsang hore e be khetho e bonolo bakeng sa tšireletso ea motlakase.
RCCB ke eng?
Sehatsetsi sa potoloho sa motlakase se setseng (RCCB), se tsejoang hape e le sesebelisoa sa motlakase se setseng (RCD), se etselitsoe ho sireletsa khahlanong le liphoso tsa mobu le ho tšoha ha motlakase. Se lemoha ho se leka-lekane pakeng tsa lithapo tse phelang le tse sa nke lehlakore, tse ka hlahang ha ho thibela ho kenella ha motlakase ho hloleha kapa ha ho kopana ka phoso le likarolo tse phelang ho etsa hore motlakase o lutle fatše. Ha ho se leka-lekane hona ho fumanoa, RCCB e hula le ho khaola potoloho, e leng se fokotsang kotsi ea ho tšoha ha motlakase le mollo haholo.
Li-RCCB li fumaneha ka maemo a fapaneng a kutloelo-bohloko, hangata ho tloha ho 30mA bakeng sa tšireletso ea botho ho isa ho 100mA kapa 300mA bakeng sa tšireletso ea lisebelisoa. Khetho ea kutloelo-bohloko e itšetlehile ka boemo ba ts'ebeliso le boemo bo hlokahalang ba tšireletso. Mohlala, tikolohong ea bolulo, 30mA RCCB hangata e sebelisoa ho sireletsa batho khahlanong le ho tšoha ha motlakase, ha lits'ebetsong tsa indasteri, RCCB e nang le matla a holimo a ho itšireletsa e ka sebelisoa ho sireletsa lisebelisoa.
MCB khahlanong le RCCB: Liphapang tse ka Sehloohong
Leha li-miniature circuit breaker (MCB) le li-residual current circuit breaker (RCCB) ka bobeli li bohlokoa bakeng sa polokeho ea motlakase, li etsa mesebetsi e fapaneng. Phapang e kholo e holim'a mekhoa ea tsona ea tšireletso:
- MCB: E sireletsa khahlanong le ho jara boima ba 'mele le potoloho e khutšoanyane. Ha e fane ka tšireletso ea phoso ea fatše kapa ea ho thothomela ha motlakase.
- RCCB: E sireletsa khahlanong le phoso ea lefats'e le ho sisinyeha ha motlakase. Ha e fane ka tšireletso e feteletseng kapa ea potoloho e khuts'oane.
Ka lebaka la liphapang tsena, li-miniature circuit breaker (MCBs) le li-residual current circuit breaker (RCCBs) hangata li sebelisoa hammoho lits'ebetsong tsa motlakase. Motsoako ona o fana ka tšireletso e felletseng, e netefatsang polokeho ea litsamaiso tsa motlakase le basebelisi.
Tšebeliso ea MCB le RCCB
Libakeng tsa bolulo, li-miniature circuit breaker (MCB) hangata li sebelisoa ho sireletsa mabone le lipotoloho tsa motlakase, ha li-residual current circuit breaker (RCCB) li kenngoa libakeng tse nang le kotsi e kholo ea ho tšoaroa ke motlakase bakeng sa polokeho e ntlafetseng, joalo ka matloana a ho hlapela le likhichine. Libakeng tsa khoebo le tsa indasteri, lisebelisoa tsena ka bobeli li bohlokoa ho sireletsa mechine le ho netefatsa polokeho ea basebetsi.
Ka bokhutšoanyane, li-miniature circuit breaker (MCB) le li-residual current circuit breaker (RCCB) ke karolo ea bohlokoa ea sistimi ea polokeho ea motlakase. Ho utloisisa mesebetsi le lits'ebetso tsa tsona ho bohlokoa ho mang kapa mang ea amehang ho kenyeng kapa ho hlokomeleng motlakase. Ka ho kopanya li-miniature circuit breaker (MCB) le li-residual current circuit breaker (RCCB), letlooa le matla la polokeho le ka hahoa ho sireletsa khahlanong le likotsi tse fapaneng tsa motlakase, ho netefatsa tikoloho e sireletsehileng bakeng sa motho e mong le e mong.
