E koho i ka uea e like me ka waiwai i ʻae ʻia o ka hiki ke amo o kēia manawa

Pono e koho ʻia ka ʻāpana keʻa uea o ka uea i loko e like me ka hiki ke lawe ʻia o kēia manawa o ka uea, ka waiwai nalowale o ka uila i ʻae ʻia o ka laina, a me ka ikaika mechanical o ka uea.ʻO ka maʻamau, koho ʻia ka ʻili lawe uea e like me ka hiki ke lawe i kēia manawa, a laila lawe ʻia ka hōʻoia e like me nā kūlana ʻē aʻe.Inā ʻaʻole i hoʻokō ka ʻāpana keʻa i nā koi o kahi kūlana calibration, pono e koho ʻia ka mea alakaʻi e like me ka palena liʻiliʻi i ʻae ʻia ʻaʻole hiki ke hoʻokō i ke kūlana.

Uea ʻae ʻia ampacity: ʻO ka ʻae ʻia o ka uea i kapa ʻia ʻo ka ampacity palekana a i ʻole ka waiwai o kēia manawa palekana o ka uea.ʻO 65°C ka wela o ka hana i ʻae ʻia o ka uea maʻamau.Inā ʻoi aku ka mahana ma mua o kēia mahana, e ʻelemakule koke ka papa insulation o ka uea, ʻino a pohō, a hiki ke hoʻoulu i ke ahi.ʻO ka mea i kapa ʻia ʻo ka hiki ke lawe i kēia manawa o ka uea, ʻo ia ke kumukūʻai kiʻekiʻe loa i hiki ke hala no ka manawa lōʻihi inā ʻaʻole ʻoi aku ka mahana hana ma mua o 65 °C.

No ka mea, ʻaʻole pili wale ka mahana hana o ka uea i ke kahe o kēia manawa ma ka uea, akā pili pū nō hoʻi i ke kūlana wela o ka uea a me ka mahana ambient, ʻaʻole i hoʻopaʻa ʻia ka mana o ka lawe ʻana i kēia manawa.Ke hoʻohana ka uea like ʻole i nā ʻano hoʻomoe ʻokoʻa (ʻokoʻa nā ʻano hoʻomoe ʻokoʻa, ʻokoʻa nā kūlana hoʻoheheʻe wela) a i ʻole ma nā ʻano wela ambient ʻokoʻa, ʻokoʻa nō hoʻi kona hiki ke lawe i kēia manawa.E nānā i ka manual technical technical no ka hiki ke lawe i kēia manawa o nā uea me nā ʻano hoʻomoe like ʻole.

Hiki ke helu ʻia ke ʻano o ka haʻawe laina ma ke ʻano penei:

Kaapuni kūʻē maʻemaʻe maʻemaʻe hoʻokahi: I=P/U

Kaapuni kaapuni hookahi me ka inductance: I=P/Ucosφ

Kaapuni kūʻē maʻemaʻe ʻekolu ʻāpana: I=P/√3UL

Kaapuni ekolu me ka inductance: I=P/√3ULcosφ

ʻO nā manaʻo o nā ʻāpana ma nā ʻano hoʻohālikelike i luna:

P: ka mana o ka haawe, ma watts (W);

UL: ʻo ia ka volta o ka mana mana ʻekolu, ma volts (V);

cosφ: ʻo ia ke kumu mana.

I ke koho ʻana e like me ka hiki ʻana o ka lawe ʻana i kēia manawa o ka uea, ʻo ke kumu maʻamau ʻo ka hiki ʻole o ka lawe ʻana i kēia manawa ʻaʻole i emi iho ma mua o ke au i helu ʻia o ka hui laina.
