KutloisisoLi-RCCB le Li-MCBLikarolo tsa Bohlokoa tsa Polokeho ea Motlakase
Lefatšeng la ho kenya motlakase, polokeho ke ea bohlokoa haholo. Likarolo tse peli tsa bohlokoa tse bapalang karolo ea bohlokoa ho netefatseng polokeho ea motlakase ke li-residual current circuit breakers (RCCBs) le li-miniature circuit breakers (MCBs). Lisebelisoa tsena tse peli li sebeletsa merero 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 bohlokoa ba li-RCCB le li-MCB tsamaisong ea motlakase ea sejoale-joale.
RCCB ke eng?
RCCB, kapa sethibela-masalela sa potoloho ea motlakase, ke sesebelisoa sa polokeho se etselitsoeng ho thibela ho tšoha ha motlakase le mello ea motlakase e bakoang ke liphoso tsa mobu. E sebetsa ka ho beha leihlo ho leka-lekana ha motlakase o phallang ka har'a lithapo tse phelang le tse sa nke lehlakore. Tlas'a maemo a tloaelehileng, motlakase o lithapong ka bobeli o lokela ho lekana. Leha ho le joalo, haeba ho hlaha phoso, joalo ka ho lutla ka lebaka la ho hloleha ha ho kenya mocheso kapa motho e mong ea amang terata e phelang, RCCB e lemoha ho se leka-lekane hona. Ha e lemoha phapang, hangata e le tlase ho 30 mA, ea khoptjoa, e khaola motlakase hang-hang.
Li-RCCB li bohlokoa libakeng tseo kotsi ea ho tšoaroa ke motlakase e leng holimo, joalo ka matloana a ho hlapela, likhichine le kantle. Li fana ka tšireletso ea bohlokoa, haholo-holo bakeng sa lihlopha tse kotsing tse kang bana le batho ba hōlileng.
MCB ke eng?
Ka lehlakoreng le leng, di-MCB (di-miniature circuit breaker), di etseditswe ho sireletsa dipotoloho ho di-overload le dipotoloho tse kgutshwane. Ho fapana le di-RCCB, tse shebaneng le ho dutla ha motlakase, di-MCB di beha leihlo motlakase o phallang ka potoloho. Haeba motlakase o feta bokgoni bo lekantsweng ba MCB ka lebaka la ho jara motlakase o feteletseng (mohlala, disebediswa tse ngata haholo tse sebediswang ka nako e le nngwe) kapa potoloho e kgutshwane (phoso e bakang tsela e sa hanyetseng), MCB e tla kgopa mme e bule potoloho.
Li-MCB lia hlokahala ho thibela tšenyo ea lisebelisoa le lithapo, le ho fokotsa kotsi ea mollo oa motlakase o bakoang ke ho chesa haholo. Li sebelisoa hangata li-switchboard tsa bolulo le tsa khoebo ho netefatsa hore lipotoloho li sebetsa ka har'a meeli e sireletsehileng.
Phapang e kholo pakeng tsa RCCB le MCB
Leha li-RCCB le li-MCB ka bobeli e le karolo ea bohlokoa ea polokeho ea motlakase, li na le mesebetsi e fapaneng:
1. Mosebetsi: RCCB e sebelisetsoa ho sireletsa khahlanong le phoso ea lefats'e le ho sisinyeha ha motlakase, ha MCB e sebelisetsoa ho sireletsa khahlanong le ho imeloa haholo le potoloho e khutšoanyane.
2. Ts'ebetso: Maeto a RCCB ka lebaka la ho se leka-lekane ha hona joale le maeto a MCB ka lebaka la ho feta tekano ha motlakase.
3. Tšebeliso: RCCB hangata e sebelisoa libakeng tseo kotsi ea ho tšoha ha motlakase e leng holimo, athe MCB e sebelisoa ho sireletsa lipotoloho ho feta tekano.
Bohlokoa ba ho sebelisa RCCB le MCB
Bakeng sa polokeho e ntle ea motlakase, ho khothaletsoa hore RCCB le MCB li hokahane ka tatellano. Motsoako ona o fana ka tšireletso e felletseng khahlanong le liphoso tsa lefats'e le ho feta tekano ha potoloho. Ho kenngoeng ha motlakase ho tloaelehileng, MCB e tla sireletsa potoloho ho feta tekano, ha RCCB e tla netefatsa hore phallo efe kapa efe ea ho lutla e bonoa le ho sebetsoa kapele.
Ka bokhutšoanyane, li-RCCB le li-MCB ke likarolo tsa bohlokoa tsa litsamaiso tsa motlakase tsa sejoale-joale, 'me e 'ngoe le e 'ngoe ea tsona e bapala karolo e ikhethang ho sireletseng khahlanong le likotsi tsa motlakase. Ho utloisisa mesebetsi le liphapang tsa tsona ho bohlokoa ho mang kapa mang ea amehang ho kenyeng kapa ho hlokomeleng motlakase. Ka ho sebelisa lisebelisoa tsena ka bobeli, beng ba matlo le likhoebo ba ka ntlafatsa polokeho ea bona ea motlakase haholo le ho sireletsa bophelo le thepa likotsing tsa liphoso tsa motlakase.
