MaMinitary circuit breakers (MCBs) nema molded case circuit breakers (MCCBs) zvese zviri zviviri zvishandiso zvakakosha mumasisitimu emagetsi anoshandiswa kudzivirira overloads, short circuits, nezvimwe zvikanganiso. Kunyangwe chinangwa chacho chakafanana, kuchine misiyano pakati pezviviri izvi maererano ne capacitance, tripping characteristics, uye breaking capacity.

Chinopwanya Dunhu Chidiki (MCB)

A Chinopwanya dunhu diki (MCB)mudziyo wemagetsi mudiki unoshandiswa kudzivirira macircuit kubva kuma short circuit uye overloads. Unoshandiswa zvakanyanya mukuisa magetsi muzvivakwa zvekugara uye zvemabhizinesi uye wakagadzirirwa kuchengetedza macircuit ega ega kwete masisitimu ese emagetsi.

Molded case circuit breaker (MCCB)

A Molded Case Circuit Breaker (MCCB)icircuit breaker yakakura uye yakasimba inoshandiswawo kudzivirira macircuit kubva kuma short circuit, overloads, nezvimwe zvikanganiso. MCCBs dzakagadzirirwa voltage yakakwira uye current ratings dzemabhizinesi, maindasitiri uye dzimba huru.

Musiyano Mukuru Pakati peMCCB neMCB

Maumbirwo:MaMCB akaomesesa kupfuura maMCCB. MCB ine bimetallic strip inokotama kana magetsi adarika mwero wakati, ichikonzera MCB uye ichivhura circuit. Asi chimiro cheMCCB chakaoma zvikuru. Electromagnetic mechanism inoshandiswa kutanga circuit kana magetsi adarika mwero wakati. Pamusoro pezvo, MCCB ine dziviriro yemagetsi inodziya kudzivirira kubva pakuwedzeredza uye mashort circuit.

Kugona:MaMCB anowanzo shandiswa pakuderedza simba remagetsi nemagetsi muzvivakwa zvekugara nezvemabhizinesi. Kazhinji anosvika 1000V uye ane simba remagetsi riri pakati pe0.5A ne125A. MaMCCB akagadzirirwa maindasitiri nemabhizinesi makuru uye anogona kubata simba remagetsi kubva pa10 amps kusvika 2,500 amps.

Kugona Kuputsa:Kugona kutyora ndiko huwandu hwakanyanya hwemagetsi anogona kutyora circuit breaker pasina kukonzera kukuvara. Kana tichienzanisa neMCB, MCCB ine simba repamusoro rekutyora. MCCB dzinogona kukanganisa magetsi anosvika 100 kA, nepo MCB dzichikwanisa kukanganisa 10 kA kana pasi. Saka, MCCB yakakodzera zvakanyanya kushandiswa nemagetsi ane simba repamusoro rekutyora.

Hunhu hweKugumburwa:Chakanakira MCCB neMCB ndechekuti mafambiro erwendo anogadziriswa. MCCB inobvumira kugadziriswa kwega kwega kwemafambiro erwendo nekunonoka kwenguva kuti pave nekuchengetedzwa kwakanaka kwemagetsi nemidziyo. Kusiyana neizvi, maMCB ane mafambiro akagadzika uye anowanzo gadzirwa kuti atenderere pamutengo chaiwo wemagetsi.

Mutengo:MaMCCB anowanzo kudhura kupfuura maMCB nekuda kwehukuru hwawo, mashandiro awo, nezvimwewo. MaMCCB anonyanya kuva nehukuru hwakakura uye anogadziriswa mafambiro. MaMCB anowanzo kuve sarudzo inodhura zvishoma yekuchengetedza masisitimu madiki emagetsi nemidziyo.

Mhedziso

Muchidimbu, maMCCB nemaMCB anoita basa rakakosha mukudzivirira macircuit kubva kuma short circuit, overloads, nezvimwe zvikanganiso mumasystem emagetsi. Kunyangwe mabasa kana zvinangwa zvema "electrical systems" akafanana, kuchine mutsauko mukushandiswa. MaMCCB akakodzera zvirinani masisitimu makuru emagetsi ane zvinodiwa zvemagetsi zvakanyanya, nepo maMCB achidhura zvishoma uye akakodzera kuchengetedza masisitimu madiki emagetsi nemidziyo. Kuziva mutsauko uyu kuchakubatsira kusarudza circuit breaker yakakodzera zvaunoda uye kuve nechokwadi chekuti system yako yemagetsi inoramba yakachengeteka uye ichishanda zvakanaka.
