Muhurongwa hwekugovera magetsi, macircuit breaker anoshanda semudziyo wepakati wekuchengetedza kuchengetedzeka kwedunhu uye kudzivirira zvikanganiso zvemacircuit overload uye short-circuit. Kubatana pakati pemain circuit breaker nemabranch circuit breaker zvakananga kunosarudza kugadzikana kwesystem yekugovera uye kunzwisisa kwekugadzirisa zvikanganiso. Chinyorwa chino chinotsanangura muchidimbu nzvimbo yavo yepakati uye kupatsanura pfungwa dzavo dzekubatana, zvichibatsira vashandi vakakodzera nevatengi kunzwisisa nekukurumidza pfungwa huru.
Kujekesa tsananguro huru uye nzvimbo yezviviri izvi kwakakosha pakunzwisisa pfungwa yekubatana:
1.Chinhu chikuru chinopwanya dunhu, inozivikanwawo se "main breaker", yakaiswa pamutsetse we "trunk" we "power distribution system". Inodzora mamiriro e "on/off" e "distribution circuit" yese uye inotora basa rekudzivirira system yese kubva pakunyanyisa kuzara uye zvikanganiso zve "short-circuit", ichishanda se "gedhi guru" re "distribution system" rinogona kudzima magetsi kune system yese.
2.Chinopwanya dunhu rebaziinoiswa pamutsetse wega wega webazi, inoenderana nemaseketi emagetsi akadai semwenje, masoketi nemidziyo yemagetsi. Inodzora kubatidzwa/kubviswa kwebazi rimwe chete uye inodzivirira kuchengetedzeka kwesimba rebazi rayo, ichishanda se "gedhi rebazi" rehurongwa hwekugovera.
Pfungwa huru yekubatanidza kwavo nhanho yepamusoro nepasi ndeyedziviriro yakarongwa uye kukanganiswa kwakasarudzwa, izvo zvinodzivirira kuwedzera kwezvikanganiso.
●Kana paine dambudziko rekuwanda kwemagetsi kana kuti rema "short-circuit" mubazi, "branch circuit breaker" inosarudza kudzima simba rebazi rine dambudziko nenguva, ukuwo "main circuit breaker" ichiramba ichishanda zvakanaka kuti mamwe matavi asakanganiswa uye simba remagetsi richienderera mberi, zvichizadzisa chinangwa chekuti "bazi rine dambudziko chete ndiro rinodzimwa".
●Kana paine dambudziko guru (senge short circuit pa trunk line) iyo isingakwanise kubviswa ne branch circuit breaker, main circuit breaker ichatanga basa rayo rekudzivirira kuti ibvise simba remagetsi ehurongwa hwese hwekugovera, ichidzivirira kukanganisa kuti kusapararire kudunhu rese uye kukonzera kurasikirwa kukuru.
Pamusoro pezvo, pfungwa yekubatanidza inofanira kusangana nezvinodiwa zvehunhu hunoenderana nekushanda: nguva yekugumburwa uye nguva yekushanda kwemuchina mukuru wecircuit breaker inofanira kunge yakakura kupfuura yemuchina mukuru wecircuit breaker, zvichiita kuti mabranch breaker atange kushanda uye muchina mukuru webreaker ushande sedziviriro yekuchengetedza kana paine chikanganiso, zvichidzivirira mamiriro asina musoro ekuti muchina mukuru webreaker utange wagumburwa uye matavi ese anorasikirwa nesimba panguva imwe chete.
Muchidimbu, kubatana kwakadaro kwechikamu chepamusoro nepasi hakungovimbisi chete kuchengetedzeka kwesimba rebazi rimwe chete, asiwo kunochengetedza kugadzikana kwehurongwa hwese hwekugovera simba, inova musimboti mukuru mukugadzirwa nekushanda kwehurongwa hwekugovera.
