Zvakanakira uye Zvakaipira zveAir Circuit Breakers

Zvakanakira zvikuru

1. Kugona kukuru kwekucheka magetsi uye kuchengetedzeka

Dunhu reMhepo Mabreaker anogona kudzima ma fault currents anosvika makumi ezviuru emaamps zvakachengeteka, zvichipa dziviriro yakavimbika ye short-circuit kune masisitimu makuru ekugovera magetsi. Dhizaini yayo yekamuri rekudzima moto re arc inogona kutonhodza nekuparadzanisa arc zvinobudirira kudzivirira kubatidza zvakare.

2. Kuzviparadzanisa nemaziso uye kushanda kunochinjika

Zvizhinji Acb Magadzirirwo anopa mirairo yakajeka ye "kuvhura/kudzima", uye mamwe mamodheru ane mabasa ekuparadzanisa kuti ape nzvimbo dzinooneka dzekugadzirisa michina yekumashure kuti ive nechokwadi chekuti vashandi vakachengeteka. Panguva imwe chete, marongero ayo ekufamba anogadziriswa (kunonoka kwenguva refu, kunonoka kwenguva pfupi, pakarepo) anobvumira kugadziriswa kwekuchengetedza kwakanaka kudzivirira mashandiro enhema. 

3. Kugadzirisa kuri nyore uye hupenyu hurefu

Chimiro chacho chinonzwisisika zviri nyore uye chiri nyore kuongorora nekugadzirisa (sekutarisa zvinosangana nemagetsi uye kuchenesa guruva). Sisitimu yekubata inowanzo shandisa zvinhu zvisingapfeki, inogara kwenguva refu yemakanika nemagetsi, ipfupi nguva yekupwanya uye yakavimbika zvakanyanya.

4. Kuchengetedza mari uye kugona kuchinjika

Zvichienzaniswa neSF6 kana vacuum circuit breakers yemhando imwe chete, mari yekutanga inowanzova nebhenefiti. Yakakodzera masisitimu akasiyana-siyana eAC neDC uye inowanzoshandiswa mukuparadzira magetsi makuru mufekitori, transformer outlet, kudzivirira mota hombe nedzimwe nguva.

     Zvakashata zvikuru

1. Kukura uye huremu hwakakura

Sezvo nzvimbo yakakwana ichidiwa yekudzima arc uye kuputira, ma ACB anowanzo kuve akakura uye ane nzvimbo yakawanda ye switch cabinet, izvo zvisingakodzeri dhizaini diki. 

2. Kunzwa kwezvakatipoteredza

Kushanda kwayo kunokanganiswa zvikuru nemamiriro ekunze (akadai sehunyoro, guruva, kusvibiswa kwemakemikari, uye kukwirira). Munzvimbo dzakaoma, kushanda kwekudzivirira kunogona kudzikira uye zvinosangana nazvo zvinogona kuomeswa zviri nyore, zvichida kugadziriswa nguva nenguva.

3. Ruzha rweArc uye mhedzisiro

Kana mvura yakakura ikatyoka, ruzha rwe "arc" rwunogadzirwa mumhepo runoita ruzha rukuru uye voltage yakawanda inogona kuitika. Matanho akakodzera ekudzivirira voltage yakawanda anofanira kutorwa.

4. Kumhanya kwekushanda kwakaganhurirwa

Kana tichienzanisa nema vacuum circuit breakers, nezvimwewo, kumhanya kwayo kwekupwanya kunowanzova kunonoka zvishoma (asi kuchiri padanho re millisecond), uye kungasakodzera mamwe maapplication akakosha anoda kupwanya kumhanya kwakanyanya. 

5. Zvinodiwa zvekugadzirisa zvakanyanya

Kuti zvishande zvakanaka kwenguva refu, ongororo dzekugadzirisa dzinoitwa nenyanzvi, kuchenesa uye kukwiza mafuta nemagetsi zvinodiwa, zvikasadaro zvinogona kutadza kushanda zvakanaka.

mukupedzisa

Nekukwanisa kwayo kupwanya simba, kugadzikana kwayo, kuona zvakanaka uye kuchengetedza simba rayo, maair circuit breaker ane chinzvimbo chikuru mumunda wekugoverwa kwesimba guru remaindasitiri neremabhizinesi. Zvisinei, zvakaipa zvayo zvakaita sehukuru hukuru, huremu uye kunzwisisa nharaunda zvinofanirawo kufungwa nezvazvo. Mukusarudza chaiko, mwero wazvino, mamiriro enzvimbo, mamiriro enharaunda uye kugona kwekuchengetedza kwemamiriro ekushandisa zvinofanirwa kuyerwa. Kune masisitimu emagetsi emukati meimba, ACB inowanzo kuve sarudzo yakasimba; kune mamiriro ezvinhu apo nzvimbo yakanyanya kuoma kana nharaunda yakaoma, mimwe mhinduro dzehunyanzvi dzakadai sema vacuum circuit breaker angangoda kuongororwa.
