● I-ZN23-40.5 i-MV i-vacuum circuit breaker isixhobo sangaphakathi sokusabalalisa i-MV yesigaba sesithathu se-AC 50Hz, i-voltage elinganisiweyo ye-40.5kV, inokuhambelana ne-JYN35 / GBC-35 uhlobo lokutshintsha ikhabhinethi. Ilungele ulawulo kunye nokukhuselwa kwiplanti yamandla, isitishi esincinci kunye nenkqubo yokuhambisa amandla, ngakumbi ilungele iindawo zokusebenza rhoqo. I-vacuum circuit breaker luhlobo lwenqwelo yesandla, enesakhiwo esifanelekileyo, ukugcinwa okufanelekileyo, ukusetyenziswa okukhuselekileyo nokuthembekileyo.

Ukukhetha

Iimeko zokusebenza

1. Ubushushu bokusingqongileyo: umda ophezulu +40℃, umda ophantsi -15℃ (indawo ebandayo -25℃);

2. Ukuphakama: hayi ngaphezulu kwe-2000m;

3. Umswakama ohambelanayo: ixabiso lemihla ngemihla alikho ngaphezu kwe-95%, umyinge wenyanga awukho ngaphezu kwe-90%;

4. Uxinzelelo lomphunga ogcweleyo: ixabiso eliqhelekileyo lemihla ngemihla alikho ngaphezulu kwe-2.2 × 10 -3 Mpa, umyinge wenyanga awukho ngaphezu kwe-1.8 × 10-3 Mpa;

5. Ubunzima benyikima abugqithisi kwii-8 degrees;

6. Akukho mlilo, ugqabhuko-dubulo, ungcoliseko, ukonakala kweekhemikhali kunye nendawo yokungcangcazela ngamandla.

Iimbonakalo

1. Isakhiwo esipheleleyo se-circuit breaker luhlobo lwenqwelo yesandla, sebenzisa i-CT19 okanye i-CD10 indlela, inokwahlulwa ibe yi-JYN1 kunye ne-GBC ezimbini iintlobo zesakhiwo.

2. I-circuit breaker body yenziwe ngefreyimu, i-insulator, i-vacuum interrupter, i-spindle kunye ne-moving and static bracket. Umphezulu ongezantsi wesakhelo uxhotyiswe ngamavili angama-4, ukuhambisa i-breaker circuit, njl. njl i-breaker circuit ineempawu zomthamo omncinci, isakhiwo esilula, ubomi benkonzo ende, ukugcinwa lula, akukho ngozi yokuqhuma, akukho kungcola njl.

Umgaqo wokusebenza

Isaphuli sesekethe sixhotyiswe ngokutywina okuphakathi kwendawo evacuum isiphazamisi semagnethi, xa unxibelelwano oluguqukayo, olungatshintshiyo lwesiphazamisi sevacuum sahluliwe, umsantsa woqhagamshelwano uya kuvelisa i-arc yevacuum kwaye icime xa ikhoyo ngaphezulu kwe-zero. Ngenxa yesakhiwo esikhethekileyo soqhagamshelwano, i-gap yoqhagamshelwano iya kuvelisa i-longitudinal field magnetic ngexesha loqhagamshelwano lwe-arc, i-arc isasazwe ngokufanayo kumphezulu woqhagamshelwano, igcina i-voltage ephantsi ye-arc, ukwenzela ukuba isantya esincinci sombane kunye negumbi le-arc elinomgangatho ophezulu. I-arc media yokubuyisela amandla, uphucule i-breaker circuit breaking short-circuit yangoku kunye nobomi bombane.
