Mhando dzemuputsi wedunhu rakaumbwa
Ma "molded case circuit breakers" (MCCBs) zvinhu zvakakosha mumagetsi kudzivirira kuwandisa kwemagetsi uye ma "short circuit". Akagadzirirwa kukanganisa kufamba kwemagetsi kana paine chikanganiso, zvichiita kuti michina nevashandi vachengetedzeke. Kunzwisisa mhando dzakasiyana dze "molded case circuit breakers" kwakakosha pakusarudza yakakodzera kushandiswa kwayo. Chinyorwa chino chichaongorora mhando dzakasiyana dzeMCCBs, maitiro adzo, uye mashandisirwo adzo.
1. Muchina wekugadzirisa dunhu wakaumbwa wakajairika
MaMCCB akajairwa ndiwo anonyanya kuwanikwa mudzimba, mumabhizinesi, uye mumaindasitiri. Akagadzirirwa kuchengetedza macircuit kubva pakuzara uye ma short circuit. Ma breaker aya anowanzo gadziriswa nema trip settings, zvichibvumira mushandisi kugadzirisa mwero wekudzivirira zvichienderana nezvinodiwa zvemagetsi. MaMCCB akajairwa anowanikwa mumhando dzakasiyana dzemazuva ano kuti akwane zvakasiyana siyana zvinodiwa pakushandisa.
2. Muchina wekupwanya dunhu wemagetsi wakaumbwa
MaMCCB emagetsi anoshandisa tekinoroji yepamusoro kupa maficha ekudzivirira akawedzerwa. Kusiyana nemaMCCB akajairwa anovimba nemagadzirirwo ekupisa nemagineti kuti agumbuke, maMCCB emagetsi anoshandisa tekinoroji yakavakirwa pamicroprocessor. Izvi zvinobvumira marongero erwendo akanyatsojeka uye mamwe maficha akadai sekudzivirira kukanganisa kwepasi, kuona kukundikana kwechikamu, uye kugona kutaurirana. MaMCCB emagetsi akanakira mashandisirwo anoshandisa michina inonzwisisika nekuti anoderedza njodzi yekugumburwa.
3. Muchina wekupwanya dunhu weHydraulic electromagnetic molded case
Ma hydraulic electromagnetic MCCB anoshandisa hydraulic mechanism kuona kuwanda kwemagetsi uye ma short circuit. Anozivikanwa nekuvimbika kwawo uye kugona kubata ma inrush currents akakwira, rudzi urwu rwe circuit breaker rwakanakira kushandiswa muma motor uye transformer applications. Hydraulic mechanism ine nguva yekunonoka inobvumira circuit kutsungirira kuwanda kwenguva pfupi pasina kugumburwa. Iyi feature inobatsira zvikuru munzvimbo dzemaindasitiri uko michina inogona kusangana ne short current surges.
4. Muchina wekupwanya dunhu wekesi wakaumbwa une mabasa maviri
MaMCCB ane mabasa maviri anobatanidza mashandiro ema "standard" nee "electronic circuit breakers". Anopa dziviriro yechinyakare ye "thermal-magnetic" pamwe ne "electronic trip settings". Kugona uku kunoita kuti vashandisi vabatsirwe nekuvimbika kwe "thermal-magnetic" kudzivirira ukuwo vaine sarudzo yezvinhu zvepamusoro zvakaita sekudzivirira pasi. MaMCCB ane mabasa maviri akakodzera kushandiswa kunoda dziviriro yakajairwa uye zvimwe zvinhu zvekuchengetedza.
5. Muchina wekugadzirisa dunhu wakaumbwa wakakosha
MaMCCB emhando yepamusoro akagadzirirwa kushandiswa kana nzvimbo dzakasiyana. Aya macircuit breaker anogona kusanganisira zvinhu zvakaita semakontena anodzivirira mamiriro ekunze ekushandiswa panze, kusimbaradza kwakasimbiswa kwekushandiswa kwemagetsi ane simba rakawanda, kana hunhu hwakasiyana hwema "tripping" emabasa akasiyana emaindasitiri. MaMCCB emhando yepamusoro anowanzo gadziriswa kuti aenderane nezvinodiwa zveindasitiri chaiyo, zvakaita semafuta negesi, migodhi, kana simba rinogona kuvandudzwa.
Muchidimbu
Ma "molded case circuit breakers" akakosha pakudzivirira masisitimu emagetsi kubva kuzvikanganiso uye kuona kuti mashandiro akachengeteka. Kunzwisisa mhando dzakasiyana dze "molded case circuit breakers" (standard, electronic, hydraulic-magnetic, dual-function, uye specialty) kunobvumira vashandisi kusarudza "circuit breaker" yakakodzera zvavanoda. Sezvo tekinoroji ichiramba ichifambira mberi, kugona kwe "molded case circuit breakers" kuri kuchinjawo, zvichipa dziviriro yakawedzerwa uye kuvimbika kune akasiyana mashandisirwo. Ingave iri yekushandisa mudzimba, mumabhizinesi, kana mumaindasitiri, kusarudza "molded case circuit breaker" kwakakodzera kwakakosha pakuchengetedza sisitimu yemagetsi yakachengeteka uye inoshanda zvakanaka.
