Mcb Rccb: Ho Utloisisa Bohlokoa baLisebelisoa tsa Tšireletso ea Potoloho
Makala a boenjiniere ba motlakase le kaho, polokeho le tshireletso ya dipotoloho le disebediswa ke tsa bohlokwa haholo. Mona ke moo disebediswa tse kang Miniature Circuit Breakers (MCB) leLi-Residual Current Circuit Breakers (RCCB)di a sebetsa. Disebediswa tsena tsa tshireletso ya potoloho di etseditswe ho sireletsa ditsamaiso tsa motlakase le ho thibela dikotsi tse ka bang teng tse kang dipotoloho tse kgutshwane, ho jara boima ba motlakase, le ho tshoha ha motlakase. Sehloohong sena, re tla teba bohlokwa ba di-MCB le di-RCCB le karolo ya tsona ho netefatseng polokeho le botshepehi ba di-installation tsa motlakase.
MCB, e tsejoang hape e le miniature circuit breaker, ke switch ea motlakase e iketsang e etselitsoeng ho sireletsa lipotoloho tsa motlakase lipotolohong tse fetang motlakase le tse khutšoane. Li sebelisoa hangata lits'ebetsong tsa bolulo, tsa khoebo le tsa indasteri ho fana ka tšireletso bakeng sa lipotoloho ka bomong. Li fumaneha ka mefuta e fapaneng ea litekanyetso tsa hona joale, li-MCB li etselitsoe ho khopa le ho roba lipotoloho nakong ea ho jara lintho tse ngata kapa lipotoloho tse khutšoane, ka hona li thibela tšenyo ea lithapo le lisebelisoa.
Ka lehlakoreng le leng, RCCB (ke hore Residual Current Circuit Breaker) e etselitsoe ho fana ka tšireletso khahlanong le ho tšoha ha motlakase le ho thibela mello ea motlakase e bakoang ke liphoso tsa mobu. RCCB e lekola ho se leka-lekane ha hona joale pakeng tsa li-conductor tse phelang le tse sa nke lehlakore 'me e khopa potoloho haeba ho fumanoa ho lutla ha motlakase, kahoo e thibela likotsi tse ka bang teng tsa ho tšoha. Li bohlokoa ho netefatsa polokeho ea motho ka mong le ho sireletsa lits'ebetso tsa motlakase likotsing tse amanang le liphoso tsa mobu.
Motsoako oa MCB le RCCB o fana ka tšireletso e felletseng bakeng sa lipotoloho le lisebelisoa. MCB e sireletsa khahlanong le phallo e feteletseng ea motlakase le potoloho e khuts'oane, ha RCCB e sireletsa khahlanong le ho sisinyeha ha motlakase le phoso ea lefats'e. Hammoho li etsa karolo ea bohlokoa ea sistimi eohle ea polokeho ea motlakase, e netefatsang tšireletso ea batho le thepa.
Ntle le mesebetsi ea tsona ea tšireletso, li-MCB le li-RCCB li thusa ho ntlafatsa ts'epo le katleho ea litsamaiso tsa motlakase. Ka ho khaola lipotoloho tse nang le liphoso kapele, li-MCB le li-RCCB li thusa ho fokotsa nako ea ho se sebetse le ho thibela tšenyo ea lisebelisoa tsa motlakase. Sena ha se ntlafatse polokeho ea ho kenngoa feela empa hape se fokotsa kotsi ea litokiso tse turang le ho nkeloa sebaka.
Ha o kgetha di-MCB le di-RCCB bakeng sa tshebediso e itseng, ho bohlokwa ho nahana ka dintlha tse kang tekanyo ya hajwale, bokgoni ba ho robeha le kutlwisiso ho netefatsa hore sesebediswa se loketse ditlhoko tse itseng tsa ho kenngwa ha motlakase. Tshebedisano e nepahetseng pakeng tsa di-MCB le di-RCCB le yona e bohlokwa ho netefatsa tshireletso e sebetsang le ho fokotsa kotsi ya ho kgoptjwa ke bohata.
Qetellong, MCB le RCCB li bapala karolo ea bohlokoa ho netefatseng polokeho, botšepehi le tšireletso ea lipotoloho le lisebelisoa. Lisebelisoa tsena tsa tšireletso ea lipotoloho ke karolo ea bohlokoa ea lits'ebetso tsa motlakase 'me li fana ka tšireletso khahlanong le motlakase o feteletseng, potoloho e khuts'oane, ho tšoha ha motlakase le phoso ea mobu. Ka ho kenyelletsa li-MCB le li-RCCB meralong ea motlakase, baenjiniere le borakonteraka ba ka netefatsa polokeho le botšepehi ba litsamaiso tsa motlakase, qetellong ba kenya letsoho polokehong le boiketlong ba batho ka bomong le thepa.
