Muhurongwa hwekugovera magetsi, midziyo yemagetsi ine voltage shoma nemidziyo yemagetsi ine voltage yakawanda zvinhu zviviri zvikuru. Kunyangwe zvese zviri zvemidziyo yemagetsi, zvine mutsauko mukuru mumatanho ekuganhurira, magadzirirwo ekugadzira uye mamiriro ekushandiswa. Kuvhiringidza zviviri izvi kunogona kutungamira pakusarudzwa kusina kunaka uye kukanganisa kuchengetedzeka kwekugovera magetsi. Chinyorwa chino chinoongorora muchidimbu mutsauko mukuru kuti upe mareferensi anoshanda kune vanoita basa.
I. Standard Demarcation: Clear Voltage Threshold
Muganho mukuru pakati pezviviri ivoltage yakayerwa, iyo inotsanangurwa zvakajeka mumazinga eindasitiri yepasi rose (IEC, GB): voltage yakayerwa yemidziyo yemagetsi ine voltage shoma ndeye ≤1000V AC uye ≤1500V DC, ine voltage yakajairika ye220V ne380V, iri yeterminal yekugovera simba; voltage yakayerwa yemidziyo yemagetsi ine voltage yepamusoro ndeye ＞1000V AC uye ＞1500V DC, ine voltage yakajairika ye10kV, 35kV zvichikwira, iri ye transmission hub link. Zvigadzirwa zvikuru zvekambani yedu ma circuit breakers, anofukidza low-voltage (MCB, MCCB) uye medium-high voltage categories, akakodzera mamiriro akasiyana.
II. Magadzirirwo Epfungwa: Zvinodiwa Zvakasiyana zveMuviri
Midziyo yemagetsi ine voltage shoma inotora "kuchengetedzeka, nyore uye kushanda zvakanaka" sepakati. Dhizaini yacho inotarisa pakuputira zvinhu zvishoma, kuisa zviri nyore uye kudzivirira overload/short-circuit, ine chimiro chiri nyore uye mutengo unodzorwa; midziyo yemagetsi ine voltage yakawanda inotora "insulation, arc extinguishing uye kugadzikana" sepakati. Nekuda kwesimba guru remagetsi ane voltage yakawanda, zvakakosha kusimbisa kugona kwekudzivirira uye arc extinguishing (senge SF6 uye vacuum arc extinguishing), ine chimiro chakaoma uye zvinodiwa zvakanyanya pakuita.
III. Maitiro Ekushandisa: Kugadzirisa Kana Zvadikanwa
Midziyo yemagetsi ine simba shoma inoshandiswa pakugovera magetsi pachiteshi, pedyo nevashandisi, inowanikwa mudzimba, mahofisi nemafekitori madiki, ichigovera magetsi kumidziyo yechiteshi; midziyo yemagetsi ine simba guru inoshandiswa pakutapurirana magetsi nekushandura nzvimbo dzemagetsi, inowanikwa muzviteshi zvemagetsi, mafekitori makuru emagetsi nemafekitori makuru emaindasitiri, ine basa rekutapurirana magetsi ane simba guru nekudzivirira kudzika kwesimba.
Pfupiso
Musiyano uripo pakati pezviviri unobva padanho remagetsi. Midziyo yemagetsi ine simba shoma inotarisa pakureruka uye kushanda kwayo, ichishandira terminal; midziyo yemagetsi ine simba guru inotarisa pakuchengetedzeka uye kugadzikana, ichidzora hub. Kujekesa muganhu kunogona kubatsira pakusarudza nemazvo uye kudzivirira njodzi dzinogona kuitika.
Ticharamba tichigovana ruzivo rwemidziyo yemagetsi uye tichipa mamwe mareferensi ekusarudza mune ramangwana.
