Nhanganyaya yekugumburwa kwemuchina wekugadzirisa nyaya

Muputsi wedunhu wakaumbwa (MCCB) chikamu chakakosha cheindasitiri yekugovera magetsi ane simba shoma. Basa rayo guru nderekucheka kana kuparadzanisa magetsi emagetsi mukati menguva yakatarwa uye yakayerwa kuti ive nechokwadi chekuti tambo nemidziyo zvakachengeteka. Chimwe chezvinhu zvakakosha zveMCCB inzira yayo yekugumburwa, iyo inoita basa rakakosha mukupindura mamiriro emagetsi uye kudzivirira njodzi dzinogona kuitika.

MaMCCB ane nzira dzakawanda dzakajairika dzekufamba, imwe neimwe yakagadzirirwa kugadzirisa mhando chaiyo yemamiriro ekutadza uye zvinodiwa pakushanda. Nzira yekutanga ndeye single magnetic tripping, umo circuit breaker inongodonha chete kana paine short circuit fault mumutsara. Rudzi urwu rwekufamba runowanzo shandiswa pama heater circuits kana motor circuits ane overload protection kuti ape dziviriro inodiwa kune aya maapplication.

Kudzikisa kwemagetsi nemagetsi, kunozivikanwawo sekudzikisa kwecompound, ndeimwe nzira yakakosha yekudzikisa macircuit breakers emolded case. Iyi nzira inoita kuti circuit breaker idzikisike kana paine zvikanganiso zve short circuit pamutsetse kana kuti line current inopfuura rated current kwenguva yakareba. Iyi trip mode inowanzoshandiswa muzviitiko zvekugovera simba, ichipa dziviriro yakakwana kune akasiyana mashandisirwo.

Kuwedzera kune nzira dzechinyakare dzekugadzirisa, electronic tripping yave tekinoroji yepamusoro yeMCCBs. Macircuit breakers ane mayuniti ekufamba nemagetsi ane magetsi anogadziriswa, magetsi anodziya uye nguva yekufamba, izvo zvinowedzera kuchinjika uye kururama kwekudzivirira masisitimu emagetsi. Kunyange zvazvo electronic tripping ichipa kushanda kwakakura, zvakakosha kuziva kuti maMCCB anoshandisa tekinoroji iyi anowanzo kudhura zvakanyanya nekuda kwehunhu hwavo hwepamusoro.

Pamusoro pezvo, ma "circuit breakers" akasarudzika anogona kushandiswa kuchengetedza ma "motor circuits", uye ma "magnetic tripping currents" anowanzo pfuura kagumi pane "rated current". Dhizaini iyi inobatsira kudzivirira "peak currents" panguva yekutanga kwemota, zvichiita kuti ishande zvakanaka uye yakavimbika.

Nemabasa ayo akasiyana-siyana ekugumburisa, ma "molded case circuit breakers" anopa mhinduro yakakwana yekudzivirira masisitimu ekugovera ane voltage shoma. Ingava single magnetic tripping, thermal magnetic tripping, electronic tripping kana motor circuit protection, kune molded case circuit breaker inosangana nezvinodiwa zvega zvega zvekushandisa, zvichiita kuti ive chinhu chakakosha pakuona kuchengetedzeka uye kuvimbika kwemasisitimu emagetsi.
