MCCB Vs MCB Vs RCBO: Vanorevei?

MCCB ikesi yakaumbwa yedunhu redunhu, uye MCB idiki diki redunhu rinotyora. Iwo ese ari maviri anoshandiswa mumaseketi emagetsi kupa overcurrent kudzivirira. MCCBs anowanzo shandiswa mumahombe masisitimu, nepo MCBs achishandiswa mumaseketi madiki.

RCBO musanganiswa weMCCB neMCB. Inoshandiswa mumasekete umo zvese zviri zviviri overcurrent uye pfupi-circuit kuchengetedzwa kunodiwa. MaRCBO haana kunyanya kuwanda pane maMCCB kana maMCB, asi ari kukura mukuzivikanwa nekuda kwekugona kwawo kupa mhando mbiri dzedziviriro mumudziyo mumwe.

MCCBs, MCBs, uye RCBOs ose anoshanda zvakafanana basa rekutanga: kuchengetedza maseketi emagetsi kubva mukukuvadzwa nekuda kwekunyanyisa kwemamiriro ezvinhu. Zvisinei, mumwe nomumwe ane zvazvakanakira uye zvazvakaipira. MCCBs ndiwo makuru uye anodhura pane matatu sarudzo, asi anogona kubata mamhepo epamusoro uye ane hupenyu hurefu.

MCBs idiki uye isingadhure, asi ine hupenyu hupfupi uye inogona chete kubata yakaderera mafungu.MaRCBOs ndiwo akanyanya kufambira mberisarudzo, uye ivo vanopa mabhenefiti ezvese maMCCB uye MCBs mune imwe mudziyo.

Kana paonekwa kusiri kujairika padunhu, MCB kana kuti miniature circuit breaker inodzima dunhu rega. MCBs dzakagadzirwa kuti dzinzwe zviri nyore kana paine yakawandisa ikozvino, inowanzoitika kana paine pfupi dunhu.

MCB inoshanda sei? Kune marudzi maviri ekubatika muMCB - imwe yakagadziriswa uye imwe inofambiswa. Kana iyo yazvino inoyerera kuburikidza nedunhu ichiwedzera, inokonzera iyo inofambiswa macontacts kuti ibvise kubva kune yakagadziriswa mabiko. Izvi zvinobudirira "zvinovhura" dunhu uye zvinomisa kuyerera kwemagetsi kubva kune chikuru chinopihwa. Mune mamwe mazwi, iyo MCB inoita seyekuchengetedza chiyero chekudzivirira maseketi kubva pakuremerwa uye kukuvara.

MCCB (Molded Case Circuit Breaker)

MCCBs dzakagadzirirwa kuchengetedza dunhu rako kubva pakuremedza. Vane gadziriro mbiri: imwe ye overcurrent uye imwe ye over-temperature. MaMCCB anewo switch inofambiswa nemaoko yekugumbura dunhu, pamwe nebimetallic contacts dzinowedzera kana chibvumirano kana tembiricha yeMCCB yachinja.

Zvese zvinhu izvi zvinouya pamwe chete kugadzira yakavimbika, yakasimba mudziyo inogona kubatsira kuchengetedza dunhu rako. Nekuda kwekugadzirwa kwayo, MCCB inogona kuve sarudzo yakanaka kune dzakasiyana siyana dzekushandisa.

MCCB idunhu redunhu rinopaza rinobatsira kuchengetedza midziyo kubva mukukuvadzwa nekubvisa iyo huru inopihwa kana yazvino ichidarika kukosha kwekutanga. Kana yazvino ichiwedzera, vanobatika muMCCB vanokura uye vachidziya kusvika vavhura, nekudaro vachityora dunhu. Izvi zvinodzivirira kuwedzera kukuvadza nekuchengetedza michina kubva kune chikuru chinopa.

Chii Chinoita Kuti MCCB & MCB Ifanane?

MCCBs uye MCBs ese ari maviri edunhu anotyora anopa chinhu chekudzivirira kune simba redunhu. Iwo anonyanya kushandiswa mune yakaderera voltage maseketi uye akagadzirirwa kunzwa uye kudzivirira dunhu kubva kupfupi maseketi kana overcurrent mamiriro.

Nepo vachigovana zvakawanda zvakafanana, MCCBs anowanzo shandiswa kune makuru maseketi kana ayo ane mafungu epamusoro, nepo MCBs akanyanya kukodzera maseketi madiki. Marudzi ese ari maviri edunhu anotyora anoita basa rakakosha pakuchengetedza kuchengetedzwa kwemagetsi masisitimu.

Chii chinosiyanisa MCCB kubva kuMCB?

Musiyano mukuru pakati peMCB neMCCB kugona kwavo. MCB ine chiyero chepasi pe100 amps ine pasi pe18,000 amps inokanganisa rating, nepo MCCB ichipa amps yakaderera segumi uye yakakwira se2,500. Uye zvakare, iyo MCCB inoratidzira inogadziriswa rwendo chinhu kune mamwe emhando yepamusoro modhi. Nekuda kweizvozvo, iyo MCCB inonyanya kukodzera maseketi anoda huwandu hwepamusoro.

Kutevera kune misiyano mishoma yakakosha pakati pemhando mbiri dzemabreaker breaker:

MCCB imhando chaiyo yedunhu rinotyora iro rinoshandiswa kudzora nekudzivirira masisitimu emagetsi. MCBs zvakare macircuit breaker asi anosiyana pakuti anoshandiswa kumidziyo yemumba uye yakaderera simba zvinodiwa.

MCCBs inogona kushandiswa kune yakakwirira simba rinodiwa nzvimbo, senge maindasitiri makuru.

MCBsIva nedunhu rakagadzika rekufamba paunenge uri paMCCBs, dunhu rekufambisa rinofambiswa.

Panyaya yemaamps, maMCBs ane asingasviki zana maamps ukuwo maMCCB anogona kukwira se2500 amps.

Hazvigoneke kubatidza nekudzima MCB uri kure asi zvichikwanisika kuzviita neMCCB uchishandisa shunt waya.

MCCBs anonyanya kushandiswa mumamiriro ezvinhu apo kune inorema zvikuru ikozvino apo MCBs inogona kushandiswa mune chero yakaderera ikozvino dunhu.

Saka, kana uchida redunhu redunhu reimba yako, waizoshandisa MCB asi kana uchida imwe yegadziriro yeindasitiri, waizoshandisa MCCB.
