suma:
Mune engineering yemagetsi,molded case circuit breakers (MCCBs) zvinhu zvakakosha mukudzivirira masisitimu emagetsi kubva pakuremerwa, mapfupi maseketi uye mamwe maitiro ekutadza.MCCBsinowanzoshandiswa mumhando dzakasiyana-siyana munzvimbo dzekugara, dzekutengeserana uye dzemaindasitiri kuti ive nechokwadi chekushanda kwakanaka uye kwakachengeteka kwemagetsi emagetsi.Muchikamu chino, tichaongorora mashandisirwo, maitiro, uye kufunga kweMCCBs.
Kushandiswa kwemolded case circuit breaker:
MCCBsanoshandiswa mumhando dzakasiyana-siyana dzekushandisa dzinosanganisira:
1. Zvishandiso zveindasitiri: MCCBs inowanzoshandiswa mumaindasitiri ekushandisa kupa dziviriro yemagetsi masisitimu kubva mukuremerwa, mapfupi maseketi, uye mamwe marudzi ekukanganisa.Zvishandiso izvi zvinosanganisira kugadzira, oiri negesi, migodhi nedzimwe nzvimbo dzemaindasitiri.
2. Zvishandiso zvekutengesa: Molded case circuit breakers inoshandiswa mune zvekutengesa zvikumbiro, zvakadai semashopu ezvitoro, mahotera, zvivako zvehofisi, nezvimwewo, kuti zvive nechokwadi chekushanda kwakanaka uye kwakachengeteka kwemaitiro emagetsi.
3. Zvikumbiro zvekugara: Molded case circuit breakers inoshandiswa mukushandiswa kwekugara kuitira kuchengetedza kuchengetedzwa kwevanogara mumba.Inoiswa mumabhokisi ekugovera kuchengetedza matunhu kubva kune zvikanganiso zvemagetsi.
Zvinoumba molded case circuit breakers:
1. Rated current: The rated current of molded case circuit breakers yakasiyana, kubva kune mashoma amperes kusvika kune akati wandei ma amperes.Iyi ficha inoita kuti ishandiswe mumhando dzakasiyana siyana.
2. Tripping character: The molded case circuit breaker ine hunhu hwekutsika, hunova nechokwadi chekuti dunhu rinofamba pakaitika dambudziko remagetsi kudzivirira kumwe kukuvara.Unhu hwerwendo hunogona kunge huri kupisa kana magnetic.
3. High breaking capacity: Molded case circuit breaker ine high breaking capacity uye inogona kumirisana nemhosho huru iripo pasina kuparara.Ichi chimiro chinovimbisa kuti dunhu rakachengetedzwa kubva pakukuvadzwa.
4. Kusarudzwa: Mutambo wakaumbwa wechikwata chechikwata chinopa kusarudzwa kwegadziriro yemagetsi, ndiko kuti, iyo chete yakaumbwa nyaya inoputika iri pedyo nekukanganisa nzendo, asi mamwe matunhu ari mumagetsi emagetsi haana kukanganiswa.
Chengetedzo pakusarudza akaumbwa makesi edunhu mabreaker:
1. Yakatemerwa ikozvino: Paunosarudza molded case circuit breaker, chiyero chemazuva ano chegadziriro yemagetsi inofanira kusimbiswa kuti ive nechokwadi chokuti iyo molded case circuit breaker inogona kumira ikozvino pasina kugumburwa.
2. Rudzi rwekukundikana: Rudzi rwekukundikana iyo MCCB yakagadzirirwa kudzivirira pairi chinhu chakakosha pakusarudza MCCB.Semuyenzaniso, mamwe MCCBs akagadzirirwa kudzivirira kubva kupisa kukundikana, nepo mamwe akagadzirirwa kudzivirira kubva magineti kukundikana.
3. Ambient tembiricha: The ambient tembiricha yemhoteredzo uko molded case circuit breaker iri zvakare yakakosha kutariswa.MCCB ine mwero wetembiricha uye inogona kusashanda nemazvo kana tembiricha yepakati ikapfuura mwero weMCCB.
Muchidimbu: MCCB chinhu chakakosha muhurongwa hwemagetsi sezvo ichipa dziviriro kubva mukukanganisa kwemagetsi.Iyo ine akasiyana akatemerwa macurrents, hunhu hwekutsika uye kutyora simba, saka yakakodzera kune akasiyana maapplication.Pakusarudza MCCB, chiyero chazvino, mhando yekukanganisa, uye ambient tembiricha inofanirwa kutariswa kuti ive nechokwadi chekushanda kwakanaka.
