Magetsi inzvimbo inokosha zvikuru pamabasa edu ezuva nezuva. Zvisinei, pamusoro pemabhenefiti awo, anogonawo kukonzera njodzi huru kana akasabatwa nemazvo. Ndosaka kuva nemacircuit breaker akavimbika kwakakosha kuchengetedza masisitimu edu emagetsi. Miniature circuit breaker (MCB) chimwe chezvishandiso zvakadaro chinoshandiswa zvakanyanya muinjiniya yemagetsi nhasi. Muchinyorwa chino, tichaongorora pfungwa yeMCB uye kuongorora maitiro ayo, kugona kwayo, uye mabhenefiti ayo.
Chii chinonziMuchina Mudiki weDunhu reMadhiraivha(MCB)?
Muchina wekupwanya dunhu mudiki, sezita racho, imuchina wekupwanya dunhu mudiki unoshandiswa kudzivirira macircuit emagetsi kubva pakuzara kwemagetsi uye ma short circuit.MCBsanowanzo shandiswa mukushandiswa kwemagetsi mashoma uko magetsi ekutadza ari mashoma.
Seimadiki ecircuit breakersbasa here?
MaMCB akagadzirwa kuti aone zvikanganiso mumasekete emagetsi uye avhiringidze kuyerera kwemagetsi kana paine chikanganiso. Musimboti wayo wekushanda ndeye electromagnetic effect yemagetsi. Munguva yekushanda kwakajairika, magetsi anoyerera nepanosangana nemagetsi akabatana nebimetal. Bimetallic strip ine simbi mbiri dzine ma coefficients akasiyana ekuwedzera. Kana magetsi ari mustrip akadarika mwero wakati, anogadzira kupisa uye bimetallic strip inokotama. Chiito ichi chinosunungura trip mechanism, ichikanganisa kuyerera kwemagetsi, nokudaro ichidzivirira circuit kubva mukukuvadzwa.
Zvimiro zvema "miniature circuit breakers"
Saizi diki: Saizi diki yeMCBzvinoita kuti ive yakakodzera kuiswa kwemagetsi madiki.
Zviri Nyore Kuisa: Dhizaini yeMCB inoita kuti zvive nyore kuisa pasina zvishandiso zvakakosha.
Kururama: MaMCB ane hungwaru hwakanyanya pakuona ma "fault currents" nekuti anopindura nekukurumidza kune chero ma "overcurrent" ari mudunhu.
Kukwanisa kupwanya kwakanyanya: Maminiature circuit breakers ane kugona kupwanya kweshort-circuit kwakanyanya uye akakodzera kushandiswa nevoltage shoma.
Zvakanakira zveMadiki eDunhu reMaputsi
Inochengetedza Mari: MaMCB anochengetedza mari uye anopa dziviriro yemagetsi yakavimbika kumasekete.
Zviri nyore kugadzirisa: MCB inogona kugadziriswa zviri nyore mushure mekuona chikanganiso, zvichichengetedza nguva nesimba.
Kugumburwa kwesarudzo: Muchina wekupwanya dunhu mudiki une kugona kwekusarudza kugumburwa, kureva kuti, muchina wekupwanya dunhu mudiki uri pedyo nepanowanikwa zvikanganiso, nokudaro zvichideredza kukanganiswa kwezvikanganiso.
Inogara kwenguva refu: Ma "miniature circuit breakers" anogara kwenguva refu uye anogona kutsungirira mamiriro ekunze akaomarara kuti ape dziviriro yakavimbika kumasisitimu emagetsi.
Mukupedzisa
Mukupedzisa, MCB chishandiso chakakosha chinogona kupa dziviriro yekutanga kumasekete. Hazvidhuri zvakanyanya, zviri nyore kuisa uye zvinoona zvikanganiso nemazvo. MCBs ndiyo sarudzo yekutanga kune akawanda mashandisirwo emagetsi mashoma nekuda kwehukuru hwadzo hudiki uye kugona kwayo kuputsa masekete mapfupi. MCBs dzavepo kwemakore akati wandei uye dziri kuramba dzichichinja nehunyanzvi hwepamusoro uye kugona kwehunyanzvi. Saka, kusarudza MCB yakakodzera sisitimu yako yemagetsi kwakakosha kuchengetedza kuchengetedzeka, kuvimbika uye kushanda zvakanaka.
