MCCB VS MCB vs Rcbo: Vanorevei?

McCB iri yakaumbwa kesi wedunhu redunhu, uye mcb ndeye miniatured wedunhu breaker. Ivo vese vanoshandiswa mumatunhu emagetsi kupa kudzivirirwa zvakanyanya. McCB inowanzo shandiswa mune yakakura masisitimu, nepo mcbs ichishandiswa mumatunhu madiki.

Rcbo iri musanganiswa weMcCB uye MCB. Iyo inoshandiswa mumatunhu umo vaviri vakanyanya uye pfupi-redunhu dziviriro zvinodiwa. Rcbos haina kujairika kupfuura mccbs kana mcbs, asi vari kukura mukuzivikanwa nekuda kwekugona kwavo kupa marudzi maviri ekudzivirira mune imwe mudziyo.

McCBS, MCBS, uye RCBOS zvese zvinoshanda zvakafanana basa: kuchengetedza matunhu emagetsi kubva kukuvara nekuda kwemamiriro ezvinhu akanyanya. Nekudaro, ivo vaviri vane kwavo zvakanakira uye zvakaipa. McCbs ndiyo yakakura uye yakanyanya kudhura sarudzo nhatu, asi dzinogona kubata dzakakwirira dzungu uye dzine hupenyu hwakareba.

MCBS idiki uye isingadhuri, asi vane pfupi ligerpan uye inogona kungobata yakaderera mafungu.Rcbos ndivo vakanyanya kufambira mberiSarudzo, uye ivo vanopa zvakanakira zvese mccbs uye mcbs mune imwe mudziyo.

Kana paine kusarongeka kwakawanikwa mudunhu, iyo mcb kana miniature circumed otomatiki inotsemuka dunhu. MCBS yakagadzirirwa nyore nyore pfungwa kana paine zvakanyanyisa zvazvino, izvo zvinowanzoitika kana paine dunhu pfupi.

Basa reMCB rinoita sei? Kune marudzi maviri evanotaurirana muMCB - imwe yakatarwa uye imwe inokatyamadza. Kana iyo yazvino kuyerera kuburikidza nedunhu inowedzera, inokonzera iyo inokonzeresa mafambisirwo ekudzima kubva kune yakatarwa mafambisirwo. Izvi zvinobudirira "zvinovhura" dunhu uye unomisa kuyerera kwemagetsi kubva kune chikuru kupihwa. Mune mamwe mazwi, iyo MCB inoita seyero yekuchengetedza yekuchengetedza matunhu kubva pakurongedza nekukuvara.

MCCB (Yakaumbwa kesi Circed Breaker)

McCbs yakagadzirirwa kuchengetedza dunhu rako kubva pakurara. Ivo vanoratidza gadziriro mbiri: imwe yekunyanyisa uye imwe yekupedza-tembiricha. McCBS ine zvakare switch inochinjika yekupfura dunhu, pamwe neBimetalical Contacts iyo inowedzera kana chibvumirano kana iyo McCARS Tembiricha yacho ichichinja.

Zvese zvinhu izvi zvinoungana kuti vagadzire yakavimbika, chishandiso chishandiso chinogona kubatsira kuti urambe uchengeteke redunhu. Nekuda kwekugadzirwa kwayo, McCB inogona kuve sarudzo huru kune akasiyana siyana ekushandisa.

McCB mudunhu redunhu anobatsira kuchengetedza zvishandiso kubva mukukuvara nekubvisa iyo huru kuwanikwa kana iyo yazvino inodarika kukosha kwekufunga. Kana iyo yazvino inowedzera, maContaces muMcCB inowedzera uye inodziya kusvikira vavhura, nokudaro kutyora redunhu. Izvi zvinodzivirira kumwe kukuvara nekuchengetedza zvishandiso kubva kune chikuru kupihwa.

Nepo vachigoverana vakawanda kufanana, MCCB vanowanzo shandiswa kumanje madiki kana avo vane mafungu akakwira, nepo MCBS vachiyirirwa madiki madiki. Marudzi ese ari maviri emubhedha wedunhu anotamba chinzvimbo chakakosha mukuona kuchengetedzwa kwemasisitimu emagetsi.

Chii chinosiyanisa McCB kubva kuMCB?

Musiyano mukuru pakati peMCB uye MCCB ndiko kugona kwavo. An mcb ane chiyero chezviyero pasi pe100 amps ane pasi pegumi nemazana emakumi mairi ekukonzeresa chiyero, nepo McCB ichigovera amps yakaderera segumi uye yakakwira se2,500. Uye zvakare, iyo MCCB inoratidza chinhu chinogadziriswa cherwendo kune iyo inowedzera mhando dzemhando yepamusoro. Nekuda kweizvozvo, iyo McCB yakakodzera kumatunhu ayo anoda chinzvimbo chepamusoro.

Zvinotevera mashoma mashoma mashoma akasiyana musiyano pakati pemhando mbiri dzedunhu dzinovhuna:

McCB ndiyo chaiyo mhando yemubhedha wedunhu inoshandiswa kudzora uye kudzivirira magetsi masisitimu. MCBS iri zvakare dunhu redunhu asi ivo vakasiyana mukuti vanoshandiswa pamidziyo yemumba uye zvinhu zvakaderera zvinodiwa.

McCBS inogona kushandiswa kune yakakwira simba nzvimbo dzinodiwa, senge maindasitiri makuru.

McbsIva nedunhu rakatemerwa riripi nguva paMCCBS, kutenderera kwacho kunodzikama.
