I-ZW7-40.5/35KV UCHUNGECHUNGE PHANDLE OKUPHEZULU OKUPHEZULU KWEVACUUM IZIQIZI ZESIKHATHI Isithombe Esifakiwe

I-ZW7-40.5/35KV UCHUNGECHUNGE PHANDLE LWEZIQINISEKISO ZE-VACUUM EPHEZULU KAKHULU

I-ZW7 -40.5/35KV uchungechunge lwama-vacuum vacuum breaker angaphandle (okuzobizwa kamuva ngokuthi “ama-circuit breaker”) asetshenziswa ezinhlelweni zamandla ezigaba ezintathu ezine-AC 50Hz kanye ne-voltage elinganiselwe engu-40.5KV, njengokuhlukana, ukulayisha okuhlanganisiwe kwamanje, ukugcwala ngokweqile. yamanje kanye ne-short-circuit current.

Izici zesakhiwo

1. Ukusebenzisa ukucisha i-vacuum arc, amandla okuphuka aqinile, impilo ende kagesi, nokuphila komshini izikhathi ezingu-10,000;
2. Isakhiwo esilula, esingenakulungiswa, isikhathi eside sokungakhathalelwa;
3. Ukusebenza kahle kokuvikela kanye nekhono eliqinile lokulwa nokungcola;
4. Ingafakwa ngendlela yokusebenza yasentwasahlobo noma kagesi, ngokusebenza okuthembekile kwemishini nokusebenza njalo;azikho izingozi zomlilo neziqhumane;
5. Ukunemba kokulinganisa kwe-transformer yamanje eyakhelwe ngaphakathi kungafinyelela izinga le-0.2, noma ukuvikelwa kokuhlukana kwezigaba ezintathu kungenziwa;
6. Isilawuli se-condensation esakhelwe ngaphakathi singakwazi ukugcina i-circuit breaker isebenza ngokuthembekile ngaphansi kwezinga lokushisa elithile kanye nomswakama.

Izici zesakhiwo

◆ Ukushisa komoya okuzungezile: umkhawulo ophezulu +409C, umkhawulo ophansi -30 ° C (indawo evamile), -40C (indawo ye-alpine);
◆Altitude: ≤1000m (uma ukuphakama kukhuphuka, izinga lokufaka elilinganiselwe lizokhula ngokufanele);
◆Ingcindezi yomoya: akukho ngaphezu kuka-700Pa (okulingana nesivinini somoya esingu-34m/s);
◆Ukuqina kokuzamazama komhlaba: akukho ngaphezu kwamadigri angu-8;
◆ Izinga elingcolile: IV;
◆Umehluko omkhulu wansuku zonke wezinga lokushisa: ungabi ngaphezu kuka-25°C.
