Inzitizi zumuzunguruko: irashobora gufungura, gutwara no kumena umuyaga mugihe gisanzwe cyumuzunguruko, irashobora kandi gufungurwa mugihe cyihariye kidasanzwe cyumuzunguruko, gutwara igihe runaka no kumena amashanyarazi ya mashini.
Micro Circuit Breaker, yitwa MCB (Micro Circuit Breaker), nigikoresho gikoreshwa cyane kurinda ibikoresho byamashanyarazi mukubaka ibikoresho byo gukwirakwiza amashanyarazi.Ikoreshwa mukiciro kimwe nicyiciro cya gatatu cyumuzunguruko mugufi, kurenza urugero no kurinda ingufu zirenga munsi ya 125A, harimo ubwoko bune bwa pole 1P, pole ebyiri 2P, pole 3P na pole enye 4P.
Micro yamashanyarazi igizwe nuburyo bukora, itumanaho, igikoresho cyo gukingira (ibikoresho bitandukanye byo kurekura), sisitemu yo kuzimya arc, nibindi. Ihuza nyamukuru rikoreshwa nintoki cyangwa rifunze amashanyarazi.Nyuma yo guhuza kwingenzi gufunzwe, uburyo bwurugendo rwubusa bufunga imiyoboro nyamukuru mumwanya wo gusoza.Igiceri cyo kurekura birenze urugero hamwe nubushyuhe bwo gusohora ubushyuhe bwahujwe n’umuzunguruko nyamukuru ukurikirana, kandi coil yo kurekura amashanyarazi ntaho ihuriye n’amashanyarazi mu buryo bubangikanye.Iyo umuzunguruko ubaye umuzunguruko mugufi cyangwa uburemere bukabije, armature yicyuma cyurugendo rwikirenga irashushanya, bigatuma uburyo bwurugendo rwubusa bukora, kandi umubonano nyamukuru uhagarika uruziga nyamukuru.Iyo umuzenguruko uremerewe, ibintu byubushyuhe bwibikoresho byurugendo rwubushyuhe birashyuha kugirango uhetamye urupapuro rwa bimetal hanyuma usunike uburyo bwurugendo rwubusa gukora.Iyo umuzenguruko uri munsi ya voltage, armature ya undervoltage irekura.Yemerera kandi uburyo bwurugendo rwubusa gukora.
Ibisigisigi byumuzunguruko bisigaye: Ihinduranya ihita ikora mugihe amashanyarazi asigaye mumuzunguruko arenze agaciro kateganijwe.Bikunze gukoreshwa kumeneka kumashanyarazi bigabanyijemo ibyiciro bibiri: ubwoko bwa voltage nubwoko bwubu, nubwoko bwubu bugabanijwe mubwoko bwa electronique na electronique.Kumeneka kumashanyarazi bikoreshwa mukurinda ihungabana ryumuntu, kandi bigomba gutoranywa ukurikije ibisabwa bitandukanye byo guhuza amakuru no kurinda itumanaho ritaziguye.
Hitamo ukurikije intego yo gukoresha n'aho ibikoresho by'amashanyarazi biherereye
1) Kurinda guhura bitaziguye n'amashanyarazi
Kuberako ingaruka ziterwa no guhura n’amashanyarazi ari nini cyane, ingaruka zirakomeye, bityo rero kugirango uhitemo icyuma kimeneka cyangiritse gifite sensibilité nyinshi, kubikoresho byamashanyarazi, ibikoresho byamashanyarazi bigendanwa numurongo wigihe gito, bigomba gushyirwaho mumashanyarazi akora ya 30mA, igihe cyo gukora muri 0.1s kumeneka kumashanyarazi.Ku mazu yo guturamo afite ibikoresho byinshi byo murugo, nibyiza kuyashyiraho nyuma yo kwinjira muri metero yingufu zurugo.
Niba amashanyarazi amaze kumara byoroshye kwangiza icyiciro cya kabiri (nko gukora ku butumburuke), icyuma gisohora amashanyarazi gifite amashanyarazi ya 15mA nigihe cyo gukorera muri Amerika kigomba gushyirwaho mukizunguruka.Kubikoresho byubuvuzi byamashanyarazi mubitaro, hagomba gushyirwaho ibyuma bisohora amashanyarazi bifite ingufu za 6mA nigihe cyo gukora muri Amerika.
2) Kurinda itumanaho ritaziguye
Guhuza amashanyarazi mu buryo butaziguye ahantu hatandukanye birashobora gutera umuntu ibyiciro bitandukanye byangiza, bityo ibyuma bitandukanya imiyoboro yamashanyarazi bigomba gushyirwaho ahantu hatandukanye.Birasabwa gukoresha imiyoboro yameneka yamenetse ifite sensibilité yo hejuru cyane aho amashanyarazi yangiza cyane.Ahantu hatose kuruta ahantu humye ibyago byo guhungabana byamashanyarazi ni byinshi, mubisanzwe bigomba gushyirwaho amashanyarazi ya 15-30mA, igihe cyo gukora muri 0.1s yameneka yamashanyarazi.Kubikoresho byamashanyarazi mumazi, hagomba gushyirwaho ibikorwa.Kumeneka kumashanyarazi hamwe na 6-l0mA nigihe cyo gukora muri Amerika.Kubikoresho byamashanyarazi aho uyikoresha agomba guhagarara kumurongo wicyuma cyangwa mubikoresho byicyuma, mugihe cyose voltage irenze 24V, icyuma kimena amashanyarazi gifite amashanyarazi munsi ya 15mA nigihe cyo gukorera muri Amerika kigomba gushyirwaho.Kubikoresho byamashanyarazi bihamye bifite voltage ya 220V cyangwa 380V, mugihe ubukana bwubutaka bwamazu buri munsi ya 500fZ, imashini imwe irashobora gushiraho imashini yameneka yamashanyarazi ifite amashanyarazi 30mA nigihe cyo gukora 0.19.Kubikoresho binini byamashanyarazi bifite umuyaga urenga 100A cyangwa umuzunguruko wamashanyarazi hamwe nibikoresho byinshi byamashanyarazi, hashobora gushyirwaho icyuma kimena amashanyarazi gifite amashanyarazi ya 50-100mA.Iyo guhangana nubutaka bwibikoresho byamashanyarazi biri munsi ya 1000, hashobora gushyirwaho imashini yameneka yamashanyarazi ifite 200-500mA.
