ZW7-40.5/35KV INGXELO NGAPHANDLE EZINGAPHANDLE EZINGAPHANDLE KWEVACUUM IZIQINISEKISO

I-ZW7 -40.5/35KV uthotho lwangaphandle lwe-vacuum vacuum breakers (emva koku lubizwa ngokuba “zizaphuli zesekethe”) lusetyenziswa kwiinkqubo zamandla ezigaba ezithathu ezine-AC 50Hz kunye ne-voltage elinganisiweyo ye-40.5KV, njengokwahlulwa, umthwalo odibeneyo wangoku, ukulayisha ngaphezulu. yangoku kunye ne-short-circuit current.

Iimpawu zesakhiwo

1. Ukusebenzisa ukucima i-arc ye-vacuum, amandla okuqhawula amandla, ubomi obude bombane, kunye nobomi bomatshini amaxesha angama-10,000;
2. Ulwakhiwo olulula, alunakugcinwa, ixesha elide lokungabikho kokugcinwa;
3. Ukusebenza kakuhle kokugquma kunye nesakhono esinamandla sokuchasa ungcoliseko;
4. Iyakwazi ukuxhotyiswa nge-spring okanye i-electromagnetic operating mechanism, kunye nokusebenza okuthembekileyo komatshini kunye nokusebenza rhoqo;akukho bungozi bomlilo kunye nokudubula;
5. Ukuchaneka kokuchaneka kwe-transformer yangoku eyakhelweyo inokufikelela kwinqanaba le-0.2, okanye ukukhuselwa kokwahlukana kwesigaba sesithathu kunokufezekiswa;
6. Umlawuli we-condensation eyakhelwe-ngaphakathi unokugcina i-circuit breaker isebenza ngokuthembekileyo phantsi kobushushu obuthile kunye nomswakama.

Iimpawu zesakhiwo

◆ Iqondo lokushisa lomoya we-Ambient: umda ophezulu + 409C, umda ophantsi -30 ° C (ummandla jikelele), -40C (ummandla we-alpine);
◆ Ukuphakama: ≤1000m (ukuba ukuphakama kunyuka, inqanaba lokulinganisa elilinganisiweyo liya kunyuka ngokufanelekileyo);
◆ Uxinzelelo lomoya: akukho ngaphezulu kwe-700Pa (ilingana nesantya somoya esiyi-34m/s);
◆ Ubukhulu benyikima: akukho ngaphezu kwe-8 degrees;
◆ Inqanaba lokungcola: IV;
◆ Owona mahluko mkhulu wobushushu bemihla ngemihla: awukho ngaphezulu kwe-25°C.
