Motor Protection Circuit Breaker J3VE

Incazelo emfushane:

I-J3VE ewuchungechunge lwama-circuit breaker (okuzobizwa ngawo manje ngokuthi ama-circuit breaker) afanele i-AC 50Hz eyomile, i-voltage yokusebenza elinganiselwe i-AC380V, i-AC660V, futhi ikalwe ngo-0.1A kuya ku-63A yamanje.Ingasetshenziswa njengokulayishwa ngokweqile kanye nokuvikelwa kwesifunda esifushane samamotho kagesi.Ingasetshenziswa futhi njengesifunda sokusabalalisa amandla.Isetshenziselwa ukulayisha ngokweqile kanye nokuvikela isifunda esifushane semishini kagesi.Ngaphansi kwezimo ezijwayelekile, ingabuye isetshenziselwe ukushintshwa okungavamile kwemigqa kanye nokuqala okungajwayelekile kwamamotho.Lolu chungechunge lwemikhiqizo luhambisana namazinga e-GB/T14048.2 kanye ne-IEC60947-2.

Izici zesakhiwo

● Lolu chungechunge lwama-breaker circuit ikakhulukazi lwakhiwe umshini, isistimu yokuxhumana, idivayisi yokukhubeka yesistimu yokucima i-arc, isisekelo se-insulating kanye negobolondo.
● I-J3VE1 yohlobo lwama-circuit breakers ifakwe othintana nabo abasizayo.I-J3VE3 kanye ne-J3VE4 uhlobo lwe-circuit breaker aluhlonyelwe othintana nabo abasizayo, kodwa bangahlonywa izesekeli zokuxhumana ezisizayo.
● Kunezinhlobo ezimbili zohambo kuma-circuit breaker: eyodwa uhambo lokulibaziseka lwe-bimetallic lwesikhathi esiphambene ukuze kuvikelwe ukugcwala;enye iwuhambo olusheshayo lukazibuthe lokuvikela isiyingi esifushane.I-circuit breaker nayo inedivayisi yesinxephezelo sezinga lokushisa, ngakho izici zokuvikela azithintwa izinga lokushisa le-ambient.
● I-J3VE1, J3VE3 kanye ne-J3VE4 ama-circuit breaker asebenza ngenkinobho, i-knob nesibambo ngokulandelanayo.
● I-breaker circuit ifakwe phambi kwebhodi.I-J3VE1, i-J3VE3, ama-circuit breakers nawo anekhadi elijwayelekile lokukhweza, elingafakwa ngokuqondile kumzila wesitimela ojwayelekile onobubanzi obungama-35mm (kufanele ahambisane ne-DINEN50022).
● Indlela ye-J3VE3 kanye ne-J3VE4 ye-circuit breaker isebenzisa izakhiwo ezisheshayo nezisheshayo, futhi amadivaysi abo okukhubeka anezici zamanje ezilinganiselwe, ngakho-ke i-circuit breaker inamandla aphezulu okuphuka kwe-short-circuit.
● Ingaphambili le-breaker yesekethe linesikhombi sokulungisa ukusebenza kwamanje kwedivayisi ekhubekayo, esingasetha ijika elijikayo ngaphakathi kwebanga elishiwo.
● I-circuit breaker ingaxhunywa nezinto ezisetshenziswayo ezifana nokukhishwa kwe-undervoltage, ukukhishwa kwe-shunt, ukukhanya kwenkomba, isikhiya, nezinhlobo ezahlukene zokuvikela zezindawo ezivalekile.Sicela ucacise uma u-oda.
