Itandukaniro riri hagati ya MCB na MCCB

Hari ubwoko bubiri busanzwe bwa circuit breakers bukoreshwa cyane mu bikorwa bitandukanye:ibikoresho byo gucana imiyoboro y'amashanyarazi byabumbwe (MCCBnautumashini duto two gukata uruziga (MCB). Zombi ni ingenzi mu buryo bw'amashanyarazi, zitanga uburinzi ku buremere bw'amashanyarazi n'imiyoboro migufi. Ariko, hari itandukaniro rikomeye hagati y'ubwo bwoko bubiri bw'imiyoboro igabanya amashanyarazi, kandi gusobanukirwa iri tandukaniro ni ingenzi mu guhitamo ibicuruzwa bikwiye gukoreshwa mu buryo bwihariye.

Inshingano nyamukuru ya MCCB ni ugutanga uburinzi bw'amashanyarazi n'uburinzi bw'amashanyarazi mu buryo buciriritse mu miyoboro y'amashanyarazi ikoresha ingufu nke n'uburinzi bw'amashanyarazi. Bizwiho kuba byizewe kandi bihamye, bigatuma bikundwa cyane mu nganda. Ku rundi ruhande, imiyoboro mito ikoresha uburinzi mu byuma bikwirakwiza amashanyarazi mu nyubako. Nubwo ari imiyoboro ikoresha uburinzi bw'amashanyarazi, hari itandukaniro riri hagati ya MCCB na MCB rigomba kwitabwaho mu guhitamo ibicuruzwa bikwiye gukoreshwa mu buryo bwihariye.

Mbere na mbere, imashini zikoresha amashanyarazi n'izikoresha amashanyarazi ziciriritse zigomba kubahiriza amahame shingiro y'ibicuruzwa kandi zikagira ihame rimwe ry'imikorere nk'imashini zikoresha amashanyarazi. Ariko hari itandukaniro rigaragara hagati yazo mu bijyanye n'ibipimo by'amashanyarazi n'imashini ndetse n'ahantu ho gukorera hakwiriye.

Kimwe mu bitandukanya MCCB na MCB ni ibipimo by'amashanyarazi bashobora gukoresha. MCCB ifite amanota agera kuri 2000A, bigatuma ikwirakwira mu byumba binini n'imizigo iremereye y'amashanyarazi. Ku rundi ruhande, MCB zifite amanota ntarengwa y'amashanyarazi ya 125A, ibi bikaba bigabanya ubushobozi bwazo kandi bigatuma zikwirakwira mu bikorwa bito. Iri tandukaniro mu manota agezweho bivuze ko MCCB zikwiriye cyane mu nganda n'ubucuruzi aho imizigo minini y'amashanyarazi ikunze gukoreshwa, mu gihe MCB zikoreshwa mu mazu n'ubucuruzi buto.

Uretse ibipimo by'amashanyarazi, hari n'itandukaniro mu bipimo bya mekanike hagati ya MCCB na MCCB. Urugero, insinga zihujwe na MCCB akenshi ziba nini, aho ubuso ntarengwa burenga metero kare 35. Mu buryo bunyuranye, MCB yagenewe gukoresha insinga nto kandi ikwiriye ahantu hagera kuri metero kare 10. Iri tandukaniro rya mekanike bivuze ko MCCB ikwiriye cyane mu gucunga sisitemu nini z'amashanyarazi, mu gihe MCB ikwiriye cyane mu bikorwa bito.

Ikindi kintu cy'ingenzi cyo kwitaho ni aho akazi gakorerwa. MCCB zagenewe gukoreshwa ahantu hatandukanye, harimo n'inganda n'ubucuruzi. Zishobora kwihanganira imitwaro iremereye y'amashanyarazi kandi ziraramba, bigatuma zikoreshwa aho kwizerwa ari ngombwa. MCB zo, ku rundi ruhande, zagenewe gukoreshwa mu nyubako z'amashanyarazi kandi zikwiriye cyane ahantu ho gutura no mu bucuruzi buto.

Muri make, nubwo MCCB na MCB byombi ari ibice by'ingenzi mu buryo bw'amashanyarazi, byagenewe gukoreshwa mu buryo butandukanye kandi bifite itandukaniro rikomeye mu bipimo byabyo by'amashanyarazi n'imashini. Gusobanukirwa iri tandukaniro ni ingenzi mu guhitamo ibicuruzwa bikwiye gukoreshwa mu buryo runaka, byaba ari ibidukikije by'inganda, ubucuruzi cyangwa ibidukikije byo guturamo. Mu gusuzuma ibintu nk'ibipimo bigezweho, ibipimo bya mashini n'ibidukikije bikora, icyemezo gishingiye ku makuru gishobora gufatwa mu gihe cyo guhitamo MCCB na MCB ku buryo runaka bw'amashanyarazi.
