Musiyano uripo pakati peAC MCB neDC MCB

Musiyano uripo pakati peChinopwanya dunhu diki cheAC(MCB) uyeDC miniature circuit breaker(MCB) chinhu chakakosha pakudzivirira macircuit. Kunzwisisa misiyano iyi kwakakosha pakusarudza circuit breaker yakakodzera zvaunoda. Semunhu anotungamiraMugadziri weMCB, takazvipira kukupa ruzivo rwaunoda kuti uite sarudzo dzakarongeka.

Kutanga, ngatitaurei nezvemacircuit akakodzera emhando mbiri idzi dzemaminiature circuit breakers. Maminiature circuit breakers eAC anonyanya kugadzirwa kuti ashandiswe pama alternating current (AC), nepo maDC miniature circuit breakers akakodzera ma direct current (DC). Izvi zvinodaro nekuti pane musiyano mukuru munzira yekuyerera kwemagetsi uye shanduko yemagetsi muma AC neDC circuit. Nokudaro, mhando dzakasiyana dzema circuit breakers dzinofanira kugadzirwa uye kugadzirwa zvakananga kune rudzi rwese rwe circuit.

Tichienderera mberi nehurukuro pamusoro pekuti maMCB aya anoshanda sei, maAC circuit breakers anoshandisa magnetic trigger kushandura magetsi ari kuyerera nepakati pe coil kuita magnetic field. Simba iri remagineti rinozosunda iron core kuti ritange switch, zvichinyatso pwanya circuit. Kusiyana neizvi, maDC miniature circuit breakers anopwanya circuit kuburikidza ne fuse. Kana magetsi adarika mwero wakati, fuse inopisa yonyunguduka, zvichikanganisa circuit.

Panyaya yekudzivirira, maDC miniature circuit breakers anowanzo kupa dziviriro yepamusoro pane maAC circuit breakers. Kazhinji, maDC miniature circuit breakers anofanirwa kusangana neIP67 protection level kuti ave nechokwadi chekudzivirira kunobudirira kubva kuguruva nemvura. Kune rumwe rutivi, maAC miniature circuit breakers anowanzo fanirwa kuwana IP54 protection rating. Aya mazinga ekudzivirira akakosha pakuona kuvimbika uye hupenyu hwebasa recircuit breaker, zvichiita kuti zvive chinhu chakakosha chekufunga nezvacho.

Kusiyana kwemagadzirirwo kunoitawo basa rakakosha mukusiyanisa maAC neDC MCB. Nekuda kwekugadzikana kwakashata kwemagetsi eDC, DC miniature circuit breaker inoda simba rakasimba kuti ive nechokwadi chekuti inoshanda zvakanaka. Pamusoro pezvo, maDC MCB anofanirwa kuratidza kugadzikana kuri nani kwekupisa uye kugara kwenguva refu kudzivirira chero kukundikana kwese musystem. Izvi zvinoratidza kukosha kwekusarudza maMCB akagadzirirwa zvakananga maDC circuits, sezvo akagadzirirwa kutsungirira matambudziko akasiyana anokonzerwa nemasystem eDC power.

Muchidimbu, musiyano mukuru uripo pakati peAC miniature circuit breakers neDC miniature circuit breakers uri mudunhu rinoshanda, musimboti wekushanda, mwero wekudzivirira uye dhizaini. Pakusarudza pakati pemhando mbiri idzi dzeMCBs, mamiriro chaiwo ekushandiswa uye zvinodiwa zvesystem yemagetsi zvinofanirwa kufungwa. Semugadziri weMCB ane mukurumbira, tinogona kukubatsira kusarudza circuit breaker inonyatsokodzera zvaunoda, tichivimbisa dziviriro yakakwana yedunhu uye rugare rwepfungwa.
