ʻO ka mea haki kaapuni AC vacuum kiʻekiʻe o waho 40.5KV HW-12 VCB nā mea haki kaapuni yueqing

1. Pono ke keʻena hoʻololi 4000A i helu ʻia i kēia manawa e hoʻoikaika i ka hoʻoluʻu ʻana o ka ea
2 Ke emi ka au haki pōkole i helu ʻia ma mua o 40KA, Q = 0.3s; ke ʻoi aku ka nui o ke au haki pōkole i helu ʻia ma mua o 40KA, Q = 180s

Hōʻuluʻulu manaʻo

ʻO ka mea haki kaapuni hakahaka AC kiʻekiʻe o waho ʻo hW-12 kahi mea hoʻololi au o waho me ka uila i helu ʻia o 40.5k a me 50H ʻekolu-pae AC. Hoʻohana nui ʻia no ka hoʻokaʻawale ʻana a me ka pani ʻana i ka pūnaewele hoʻolaha. ke au ukana, ke au overload a me ke au kaapuni pōkole i loko o ka ʻōnaehana mana. kūpono ia no ka pale a me ka kaohi ʻana i nā ʻōnaehana hoʻolaha mana o nā substations a me nā ʻoihana ʻoihana a me nā ʻoihana mining. kūpono ia no nā pūnaewele mana kuaʻāina a me nā wahi i hana pinepine ʻia. kūpono loa no nā pono o ka pūnaewele kūlanakauhale a me ka pūnaewele kuaʻāina.
