Yuye mhando yakaumbwa kesi yedunhu breaker sarudzo zvinhu

Zvinoenderana nechimiro cheiyo yedunhu breaker classification, kune yepasirese mhando, epurasitiki shell mhando, epurasitiki kesi circuit breaker, iyo inokodzera rated voltage 690V, frequency 50/60Hz, yakayerwa ikozvino 16 kusvika 1600A yekugovera sisitimu kana se transformer, mota. , capacitor nemimwe midziyo yekudzivirira.Kunyanya kugovera simba remagetsi, ita bazi uye midziyo yemagetsi yakawandisa, dunhu pfupi, leakage point uye under-voltage dziviriro, inogona zvakare kushandiswa kumutsara uye midziyo yemagetsi haiwanzo kutendeuka.Inoshandiswa zvakanyanya muindasitiri uye zvekurima, zvekufambisa, zvicherwa, kuvaka kwevagari uye kudzivirira kwenyika uye mamwe madhipatimendi, kutapurirana uye kugoverwa kwesimba, kutonga kwedunhu nekudzivirira kunoita basa rakakura, kushandiswa kukuru, kwakasiyana siyana kwezvigadzirwa.Nekuti vashandisi havanzwisise hunhu uye tekinoroji zvinodiwa zveMCCB zvakadzika kana zvizere, mamwe maconcepts ari nyore kuvhiringika kune mumwe nemumwe, uye kazhinji pane zvikanganiso nekusanzwisisa mukushandisa kunoshanda.Iwo akakosha ma paramita ayo mushandisi anofanirwa kutarisisa pakusarudza nekushandisa MCCB anounzwa zvakadzama.Ikozvino, tsananguro yegomba furemu nhanho yebreaker inoshandiswa kubatsira mushandisi kusarudza zvine musoro kushandisa MCCB.

Circuit breaker shell bracket giredhi

Circuit breaker housing frame rating ndiyo yakayerwa ikozvino yerwendo rukuru runogona kuiswa pafuremu uye dzimba dzepurasitiki dzehukuru hwakafanana.

Iyo yakarongerwa ikozvino yedunhu rebreaker ndiyo yazvino iyo rwendo rwemufambi wedunhu runogona kupfuura kwenguva yakareba, inozivikanwawo seyakayerwa ikozvino yerwendo rwedunhu.

Kune akasiyana siyana esheko furemu yekuyeresa ikozvino mune imwecheteyo akateedzana, uye akasiyana akayerwa azvino mune imwechete shell furemu rating ikozvino.Semuenzaniso, kune 16A, 20A, 25A, 32A, 40A, 50A, 63A, 80A uye 100A yakarongwa ikozvino mu100A shell uye furemu rating;Kune 100A, 125A, 160A, 180A, 200A, 225A yakatarwa ikozvino mu225A shell uye furemu kirasi.Kune 100A yakayerwa ikozvino mune ese 100A uye 225A goko bracket mamakisi, asi saizi, chimiro uye kutyora kugona kwedunhu rinotyora zvakasiyana.Nokudaro, rudzi runofanira kuzadzwa zvakakwana pakusarudza, kureva, iyo yakatemerwa ikozvino yemutambo wedunhu mukati meiyo yakarongerwa ikozvino yeiyo chaiyo shell bracket giredhi.Iyo yakarongerwa ikozvino kurongeka inosarudzwa maererano neiyo yekutanga coefficient ye (1.25): kune rumwe rutivi, inosangana uye inosangana nezvinodiwa zveiyo yakanyanya kurongeka ikozvino yedunhu nemagetsi zvikamu;Imwe yacho ndeyekumira, kuitira kuti uwane kushandiswa kwakanyanya kwewaya uye kugadzirisa mabhenefiti.Naizvozvo, mamakisi aanopa ndeaya: 3(6), 8, 10, 12.5, 16,20, 25, 32, 40, 50, 63, 80,100, 125, 160, 200, 250, 315, 400A, nezvimwewo. yemutemo uyu, apo mutoro wakaverengwa wemutsara uri 90A, chete 100A tsanangudzo inogona kusarudzwa, saka kushanda kwayo kwekudzivirira kunokanganiswa kune imwe nzvimbo.

Tripper yazvino kuseta ndipo kana mutatu agadziridzwa kune yekushanda ikozvino kukosha.Inoreva iyo yakarongerwa ikozvino Muzhinji, kukosha kwechiito chezvino, semuenzaniso: overcurrent set to 1.2, 1.3, 5, 10 times the current, yakanyorwa IR = 1.2In, 1.3In, 5In, 10In, nezvimwewo. Iye zvino mamwe ma-trippers emagetsi, kuremerwa kwayo uye kunonoka kwenguva yakareba yakarongwa ikozvino inogadziriswa, iyo yakagadziridzwa ikozvino, chaizvoizvo, ichiri yakarongwa ikozvino, ndiyo yakawanda ikozvino inogona kupfuudzwa kwenguva yakareba.

Iyo yakatemerwa kushanda ikozvino ndiyo chaiyo yekushanda ikozvino yedunhu rinopwanya pane imwe voltage yekushanda kana vabatsiri vanobatana (zvishandiso) vakaiswa.Ikozvino ndeye 3A kana 6A, iyo inoshandiswa kutonga nekudzivirira dunhu.
