Kudiwa kwemidziyo yemagetsi yepamusoro yekuchengetedza kwakura kupfuura kare. Maindasitiri nemabhizinesi anoda hunyanzvi hwakakura kuti ave nechokwadi chekuti magridi emagetsi akasimba, akachengeteka uye anodzivirira midziyo yavo. Kuvandudzwa kwema "circuit breakers" akangwarauye mashandiro avo akavimbika achinja zvinhu zvakanyanya muindasitiri iyi. Nhasi, tichanyatsoongorora kutichinodzora mhepo (ACB)ndiyo hwaro hwechero hurongwa hwemazuva ano hwekugovera magetsi.
IyoAkangwara Universal Circuit Breaker, yatinodaidza kutiACB, mudziyo wekudzivirira mutsva unovimbisa grid yakagadzikana uchishandisa mabasa akangwara. Une zvinhu zvakati wandei zvinosanganisira ma trip units, ma sensors nema actuator. Ma circuit breakers ane basa rekugumburwa kana paine mamiriro asina kujairika mu grid, akadai sekuwedzerwa kwemagetsi, short circuit kana ground fault, uye kuparadzanisa circuit zvachose. Kana ikagumburwa, mudziyo unoyambira mushandi wesystem kuburikidza ne alarm kana signal.
ACB inoshanda zvakanyanya nekuti inogona kutaurirana nezvikamu zvakasiyana-siyana zvemagetsi, kusanganisira mamwe macircuit breaker, mamita, uye marelay, zvichibvumira kutariswa kwakakwana kwegrid. Uchenjeri uhwu hunokosha pakuvandudza kuchengetedzeka, mashandiro uye purofiti yekuisa magetsi. Nekuunganidza nekugadzirisa data nezvesimba, simba uye maparameter akawanda, macircuit breaker anobatsira kuchengetedza michina, kudzivirira njodzi uye kuwedzera kushanda zvakanaka.
MaACB anowanikwa muhukuru hwakasiyana-siyana uye mhando dzakasiyana, zvichitigonesa kusangana nezvinodiwa zvakasiyana-siyana zvekushandisa muindasitiri. Maumbirwo emudziyo uyu anosanganisira circuit breaker body ine magetsi, mashandiro uye release. Kugadzirwa kwawo kwekubatana kwakagadzirwa nebrass yakavezwa ine multi-layer composition uye kushivirira kwakanyatsojeka kunoita kuti magetsi ashande zvakanaka uye agare kwenguva refu. Maitiro awo ekushanda anogona kunge ari emagetsi kana echitubu, zvichitibvumira kuisa macircuit breaker akavimbika, zvinobudirira uye zviri nyore mumamiriro ezvinhu akaoma.
Chekupedzisira, chikamu cherwendo ndicho chinonyanya kukosha pakuongorora mafungu emhepo (trip unit) sezvo chichiongorora mafungu emhepo uye chichiona kuti chinofanira kufamba riini. Chikamu cherwendo chinogona kuva chemagetsi kana chemagetsi, zvichienderana nekushandiswa kwacho. Chinosanganisira CT, PT, bhodhi redunhu rekudzora uye microprocessor. CT nePT zvinoongorora magetsi nemagetsi zvichiteerana, uye zvinotumira chiratidzo kubhodhi rekudzora kuti chigadziriswe. Microprocessor inozoongorora data rechiratidzo kuti ione kana paine chinokanganisika mudunhu uye, kana zvichidikanwa, inopa murairo werwendo kuactuator, nokudaro zvichikanganisa mashandiro acho.
Muchidimbu,muputsi wedunhu wepasi rose akangwarachishandiso chakakosha chekudzivirira magetsi kuti chibudirire zvikuru mugridi yemagetsi yenyika yangu. Kuburikidza nemabasa ayo akangwara uye akavimbika, macircuit breaker anovandudza uye anovimbisa kuchengetedzeka, kushanda zvakanaka uye kushanda zvakanaka kwekuisa magetsi. Sezvo indasitiri ichiramba ichikura, kukosha kwekuchengetedzwa kwemagetsi hakufanirwe kunyanyosimbiswa. ACB inopa mhinduro dzese-mu-imwe dzinosangana nezvinodiwa zvakasiyana-siyana zvekushandisa uye dzinovimbisa kuenderera mberi kwekupa magetsi, nokudaro zvichiwedzera kuvimbika uye kubereka muzvikamu zvemaindasitiri nekutengeserana.
