● I-ZN23-40.5 i-MV vacuum circuit breaker iyidivayisi yokusabalalisa ye-MV yasendlini yezigaba ezintathu ze-AC 50Hz, i-voltage elinganiselwe engu-40.5kV, ingafaniswa nekhabhinethi yokushintsha yohlobo lwe-JYN35/GBC-35. Ifanele ukulawulwa nokuvikelwa endaweni yokuphehla amandla, isiteshi esincane kanye nohlelo lokusabalalisa amandla, ikakhulukazi ezifanele izindawo zokusebenza ezivamile. I-vacuum circuit breaker iwuhlobo lwenqola yesandla, enesakhiwo esinengqondo, ukugcinwa okulula, ukusetshenziswa okuphephile nokuthembekile.

Ukukhetha

Izimo zokusebenza

1. Izinga lokushisa kwemvelo: umkhawulo ophezulu +40℃, umkhawulo ophansi -15℃ (indawo ebandayo -25℃);

2. Ukuphakama: hhayi ngaphezu kuka-2000m;

3. Umswakama ohlobene: inani elimaphakathi lansuku zonke alikho ngaphezu kuka-95%, isilinganiso sanyanga zonke asisikhulu kuno-90%;

4. Ukucindezela kwesitimu esigcwele: inani elimaphakathi lansuku zonke alikho ngaphezu kuka-2.2 × 10 -3 Mpa,isilinganiso sanyanga zonke asiphezulu kuno-1.8×10-3 Mpa;

5. Amandla okuzamazama komhlaba aweqi amadigri angu-8;

6. Akukho mlilo, ukuqhuma, ukungcola, ukugqwala kwamakhemikhali kanye nendawo yokudlidliza okukhulu.

Izici

1. Isakhiwo sonke se-circuit breaker siwuhlobo lwenqola yesandla, sebenzisa i-CT19 noma i-CD10 indlela, ingahlukaniswa ibe yi-JYN1 ne-GBC izinhlobo ezimbili zesakhiwo.

2. Umzimba we-circuit breaker wakhiwe ngohlaka, isivikelo, isiphazamisi se-vacuum, i-spindle kanye nabakaki abahambayo nabamile. Indawo engaphansi yohlaka ifakwe amasondo angu-4, okuhambisa i-circuit breaker, njll. uhlangothi lwesokudla lohlaka lufakwe isivikelo esingu-6 njengokwesekwa, ukusetshenziswa okungaguquki okunyakazayo nokumile, isiphazamisi se-vacuum esifakwe phakathi kokusekela okuguquguqukayo, okumile, i-circuit breaker inezici zevolumu encane, isakhiwo esilula, impilo yesevisi ende, ukugcinwa okulula, akukho ngozi yokuqhuma, akukho ukungcola njll.

Isimiso sokusebenza

I-circuit breaker ifakwe isiphazamisi se-vacuum evacuum ye-longitudinal lengitudinal ephakathi nendawo, lapho ukuthintana okuguquguqukayo, okumile kwesiphazamisi se-vacuum kuhlukaniswa kushajwe, igebe lokuxhumana lizokhiqiza i-arc ye-vacuum futhi sicime lapho i-current idlula uziro. Ngenxa yesakhiwo esikhethekile sokuxhumana, igebe lokuxhumana lizokhiqiza inkambu kazibuthe efanelekile ngesikhathi sokuxhumana, i-arc isatshalaliswa ngokulinganayo ebusweni bokuxhumana, igcina i-voltage ephansi ye-arc, ukuze ijubane lokugqwala likagesi elincane kanye negumbi le-arc elinokuphakama okuphezulu. Amandla okubuyisela imidiya ye-arc, thuthukisa ikhono lamanje le-circuit breaker kanye nempilo kagesi.
