Mokokotlo oa ho Khomarela oa MCB

Li-breaker tse nyane tsa potoloho (MCB) li phetha karolo ea bohlokoa ho sireletseng lipotoloho le lisebelisoa. Li-miniature circuit breaker tsena li etselitsoe ho sitisa phallo ea motlakase ka bohona ha phoso e bonoa, ho thibela tšenyo e ka bang teng tsamaisong le ho netefatsa polokeho ea basebetsi. Karolo ea bohlokoa ea MCB ke mofuta oa trip curve, e khethollang nako ea karabelo le tekanyo ea hona joale ea circuit breaker ha e khoptjoa. Ho utloisisa mefuta e fapaneng ea trip curve ho bohlokoa ho khetheng MCB e nepahetseng bakeng sa ts'ebeliso e itseng.

Mokoloko o kgopameng wa sekgahla se senyenyane sa potoloho o bolela kamano pakeng tsa mokoloko o kgopameng wa makenete le mokoloko o lekantsweng. Mekoloko e fapaneng ya maeto e a fumaneha, e nngwe le e nngwe e loketse mefuta e fapaneng ya meroalo le ditshebediso. Mefuta e tlwaelehileng ya mokoko wa maeto bakeng sa di-MCB e kenyeletsa Mofuta wa A, Mofuta wa B, Mofuta wa C le Mofuta wa D. Mofuta o mong le o mong o na le dibopeho tse ikgethang mme o loketse maemo a fapaneng, ho tloha ho sireletsa dipotoloho tsa elektroniki tsa semiconductor ho isa dibakeng tsa ho qala mojaro o boima.

Kou ea ho khopa ea Mofuta oa A e khetholloa ka motlakase oa ho khopa oa makenete oa (2-3) In. E loketse ho sireletsa lipotoloho tsa elektroniki tsa semiconductor, lipotoloho tsa tekanyo ea li-transformer tsa matla a tlase, kapa litsamaiso tse nang le mela e melelele le maqhubu a manyane. Li-MCB tsa Mofuta oa A li etselitsoe ho fana ka karabelo e potlakileng liphosong tsa maemo a tlase, e leng se etsang hore li be ntle bakeng sa lisebelisoa tsa elektroniki tse bonolo le lipotoloho tse hlokang tšireletso e nepahetseng.

Motlakase oa makenete oa mofuta oa B o ka etsang hore motlakase o se ke oa sebetsa o lekana le (3-5) In. Li-MCB tsena li loketse meroalo e thibelang mocheso le lipotoloho tsa mabone a motlakase o tlase. Li sebelisoa hangata litsamaisong tsa kabo ea motlakase lapeng, lisebelisoa tsa lapeng le tšireletso ea polokeho ea motho ka mong. Li-MCB tsa mofuta oa B li fana ka tšireletso e sebetsang bakeng sa mefuta e fapaneng ea lits'ebetso tsa bolulo le tsa khoebo.

Motlakase oa makenete oa curve ea ho qhaqha ea Mofuta oa C ke (5-10) In. Li-MCB tsena li loketse meroalo e susumetsang le lipotoloho tsa mabone tse nang le kutloelo-bohloko e phahameng. Li sebelisoa hangata ho sireletsa mela ea kabo le lipotoloho tsa mabone tse nang le maqhubu a phahameng a ho khantšoa ha motlakase. Li-MCB tsa Mofuta oa C li na le mekhoa e mengata 'me li loketse ho sebelisoa liindastering tse fapaneng moo ho hlokahalang tšireletso e nepahetseng ea meroalo e susumetsang.

Kou ea ho qhaqha ea Mofuta oa D e khetholloa ka motlakase oa ho qhaqha oa makenete oa (10-20) In. Li-MCB tsena li loketse litsamaiso tse nang le meroalo e susumetsang haholo le maqhubu a maholo a ho qhaqha. Hangata li sebelisoa ho sireletsa lisebelisoa tse nang le maqhubu a ho qhaqha a phahameng, joalo ka li-transformer le li-valve tsa solenoid. Li-MCB tsa Mofuta oa D li etselitsoe ho mamella meroalo e boima le ho fana ka tšireletso e tšepahalang libakeng tsa indasteri.

Ka bokhutšoanyane, ho utloisisa li-curve tse khopameng tsa mefuta e fapaneng ea li-miniature circuit breaker ho bohlokoa ho khetheng MCB e nepahetseng bakeng sa ts'ebeliso e itseng. Ebang li sireletsa lipotoloho tse bonolo tsa elektroniki kapa lisebelisoa tse boima tsa indasteri, li-MCB tse nang le mofuta o nepahetseng oa curve ea trip li bohlokoa ho netefatsa polokeho le ts'epo ea litsamaiso tsa motlakase. Ka bokhoni ba tsona bo fapaneng, li-MCB li ntse li le karolo ea bohlokoa ea polokeho le ts'ireletso ea motlakase liindastering tse fapaneng.
