KutloisisoMCCBleMCBLiphapang tse ka Sehloohong le Litšebeliso

Mafapheng a boenjiniere ba motlakase le tshireletso ya potoloho, mantswe a mabedi a atisa ho sebediswa: MCB (miniature circuit breaker) le MCCB (molded case circuit breaker). Disebediswa tsena ka bobedi di etsa mosebetsi wa bohlokwa wa ho sireletsa dipotoloho ho tswa ho overloads le dipotoloho tse kgutshwane, empa di fapana haholo ka moralo wa tsona, tshebediso le bokgoni ba tsona ba tshebetso. Sengolwa sena se ikemiseditse ho hlakisa dipharologanyo pakeng tsa MCB le MCCB, ho o thusa ho utlwisisa hore na o lokela ho sebedisa e nngwe le e nngwe neng le hobaneng.

MCB ke eng?

Sehatsetsi sa potoloho se senyenyane (MCB) ke sesebediswa se senyenyane se sebediswang ho sireletsa dipotoloho tsa motlakase ho di-overload le dipotoloho tse kgutshwane. Di-MCB hangata di sebediswa ditshebedisong tsa bodulo le tsa kgwebo tse nang le di-current tse tlase haholo, hangata di tloha ho 0.5A ho isa ho 125A. Ha motlakase o feta boemo bo rerilweng esale pele, MCB e a kgothoha ka boyona, e thibela tshenyo e ka bang teng potolohong le disebedisweng tse hokahantsweng.

Li-Miniature circuit breaker (MCB) li fana ka linako tsa karabelo tse potlakileng, e leng tsa bohlokoa bakeng sa ho fokotsa tšenyo e bakoang ke liphoso. Li boetse li ka setafatsoa, ​​​​ho bolelang hore hang ha phoso e se e felile, MCB e ka setafatsoa habonolo ntle le ho nkeloa sebaka. Tšobotsi ena e etsa hore MCB e be khetho e tsebahalang bakeng sa ho sireletsa lipotoloho tsa mabone, li-socket tsa motlakase le lisebelisoa tse nyane.

MCCB ke eng?

Ka lehlakoreng le leng, di-molded case circuit breakers (MCCBs) di tiile haholoanyane mme di etseditswe ditshebediso tse hodimo tsa motlakase, hangata di tloha ho 100A ho isa ho 2500A. Di-MCCB di sebediswa hangata dibakeng tsa diindasteri le tsa kgwebo tse nang le meroalo e boima ya motlakase. Di fana ka tshireletso ya ho jara boima ba motlakase, ya potoloho e kgutshwane, le ya phoso ya mobu, e leng se etsang hore di lokele mefuta e mengata ya ditshebediso.

Li-molded case circuit breakers (MCCBs) li na le litlhophiso tse ka fetoloang tsa leeto, tse lumellang basebelisi ho etsa hore boemo ba tšireletso bo lumellane le litlhoko tse itseng tsa sistimi ea motlakase. Tšobotsi ena e thusa haholo libakeng tsa indasteri moo litlhoko tsa hajoale tsa lisebelisoa li ka fapana. Li-MCCB hangata li kenyelletsa likarolo tse tsoetseng pele joalo ka tlhokomelo le puisano tse hole, ho ntlafatsa ts'ebetso ea tsona lits'ebetsong tse rarahaneng tsa motlakase.

Phapang ea bohlokoa pakeng tsa MCB le MCCB

1. Tekanyetso ea Hona Joale**: Phapang e kholo ka ho fetisisa pakeng tsa MCB le MCCB ke tekanyo ea tsona ea hona joale. MCB e loketse lits'ebetso tsa hona joale tse tlase (ho fihlela ho 125A), ha MCCB e loketse litlhoko tse phahameng tsa hona joale (100A ho isa ho 2500A).

2. Ho feto-fetoha: Li-MCB li na le litlhophiso tse tsitsitseng tsa maeto, athe li-MCCB li fana ka litlhophiso tse feto-fetohang tsa maeto, e leng se lumellang ho tenyetseha ho hoholo ha ho sireletsa potoloho.

3. Tšebeliso: Li-MCB li sebelisoa haholo-holo lits'ebetsong tsa bolulo le tsa khoebo tse bobebe, athe li-MCCB li etselitsoe ts'ebeliso ea indasteri le ea khoebo e boima, e kenyeletsang meroalo e meholo le litsamaiso tse rarahaneng haholoanyane.

4. Boholo le Moralo: Li-Miniature circuit breaker (MCB) ka kakaretso li nyane ebile li nyane ho feta li-molded case circuit breaker (MCCBs), e leng se etsang hore ho be bonolo ho li kenya libakeng tse fokolang. Li-molded case circuit breaker (MCCBs) li kholoanyane, li hloka sebaka se eketsehileng, 'me hangata li kenngoa li-switchgear assemblies.

5. Litšenyehelo: Li-miniature circuit breaker (li-MCB) ka kakaretso li theko e tlase ho feta li-molded case circuit breaker (li-MCCB), e leng se etsang hore e be tharollo e theko e tlaase bakeng sa lits'ebetso tse nyane. Leha ho le joalo, ts'ebetso ea tsona e eketsehileng le ts'ebetso li etsa hore e be letsete le molemo libakeng tse kholo le tse hlokang boiteko bo bongata.

Ka kakaretso

Ka bokhutšoanyane, li-miniature circuit breaker (MCB) le li-molded case circuit breaker (MCCB) ka bobeli li bapala karolo ea bohlokoa tšireletsong ea potoloho, empa lits'ebetso le bokhoni ba tsona li fapana haholo. Ho utloisisa liphapang tsena ho bohlokoa bakeng sa ho khetha sesebelisoa se nepahetseng bakeng sa litlhoko tsa hau tse ikhethileng. Hore na u sireletsa potoloho e nyane ea bolulo kapa sistimi e kholo ea indasteri, ho khetha se-circuit breaker se nepahetseng ho netefatsa polokeho, ts'epo le katleho ea lisebelisoa tsa hau tsa motlakase. Kamehla buisana le setsebi sa motlakase kapa moenjiniere oa motlakase ea tšoanelehang ho fumana tharollo e molemohali bakeng sa boemo ba hau bo ikhethileng.
