Ndezvipi zvinomiririrwa neMCB?

Madiki madiki edunhu (MCB) anonyanya kushandiswa kudzivirira macircuit kubva kuma short circuit uye overloads, uye anogonawo kushandiswa muma power distribution systems e lighting kana motors.
Inoratidzwa nekunaka uye chitarisiko chidiki, huremu hwakareruka, kushanda kwakanaka uye kwakavimbika, kugona kupwanya kwakanyanya, kukurumidza kugumburwa, kuiswa nyore kwesimbi dzinotungamira uye kugara kwenguva refu.
Pane zviratidzo zvakawanda paminiature circuit breaker (MCB). Zvinorevei?

1. Zvinorevei kuti “C20”?
20 ndiyo current yakarongwa, saka C inorevei? C inomiririra hunhu hwekugumburwa kwecircuit breaker, iyo yakakamurwa kuva mhando dzeB, C neD;
Rudzi B (3-5) In inogumburwa nekatatu kusvika kashanu kupfuura simba remagetsi rakarongwa. Yakakodzera kutakura zvinhu zvinodzivirira chete uye maseketi emwenje asina kusimba zvakanyanya. Rudzi urwu rwemutoro rune simba diki rekutanga uye rinowanzo shandiswa mumwenje wepamba kana munzvimbo dzine zvinodiwa zvekudzivirira zvakanyanya.
Rudzi C (5-10) In inogumburwa nekashanu kusvika kugumi kupfuura simba remagetsi rakarongwa. Yakakodzera kutakura zvinhu zvinosimudzira mwenje uye maseketi emwenje ane hunhu hwepamusoro, akadai semarambi etungsten halogen. Hunhu hwayo hwekutanga hune simba remagetsi rakakwirira uye hunowanzo shandiswa mukudzivirira maseketi ekugovera. uye kutakura zvinhu zvine simba remagetsi rine simba remagetsi rinotanga rakakwirira.
Rudzi D (10-14) In inogumburwa nekagumi kusvika kugumi nemana kupfuura ratio current. Yakakodzera masisitimu ekugovera magetsi ane inductance yakakura uye impact currents hombe, dzakadai semota, solenoid valves nedzimwe impact loads. Ipact loads dzakadaro dzine impact loads dzakakwira.

2.240V/400V 50Hz/60Hz zvinoreva maseketi anoshanda;
3.IEC60898 inoreva mwero wepasi rose wemagetsi weIEC60898.
4. Chii chinorehwa ne4500A iri pasi? Imagetsi here?
Imagetsi chaiwo, zvinoreva magetsi akawandisa anopwanya magetsi. Kureva kuti, kana tambo pfupi ikaitika pamutsetse, kana magetsi ari makuru kupfuura 3000A, anogona kusabatanidzwa. Iyi parameter yakasiyana kune vagadziri vakasiyana.

5. Chiratidzo ichi chinorevei?
Chiratidzo ichi chinoratidza kuti circuit breaker ine mabasa maviri ekudzivirira (kudzivirira) ekudzvinyirira zvakanyanya uye kupfupisa circuit.
