ʻO ka ʻokoʻa ma waena o ka uila hoʻokahi, ka uila ʻelua ʻāpana, a me ka uila ʻekolu

ʻO ka uila hoʻokahi-phase a me ʻelua-phase ʻelua ʻano mana lako mana. Loaʻa iā lākou nā ʻokoʻa nui i ke ʻano a me ka volta o ka hoʻoili uila.

ʻO ka uila ʻāpana hoʻokahi e pili ana i ke ʻano o ka lawe ʻana i ka uila me kahi laina pae a me kahi laina ʻole. ʻO ka laina ʻāpana, ʻike ʻia hoʻi ʻo ka laina ahi, hāʻawi i ka uila e hoʻouka, a hoʻohana ʻia ka laina kūʻokoʻa i ala e hoʻihoʻi ai i ke au. ʻO ka volta o ka uila hoʻokahi-phase he 220 volts, ʻo ia ka volta ma waena o ka laina pae a i ka laina zero.

I loko o ka ʻohana a me ke keʻena, ʻo ka uila hoʻokahi-phase ka ʻano mana maʻamau. Ma ka ʻaoʻao ʻē aʻe, ʻo ka mana mana ʻelua-phase kahi kaapuni mana i haku ʻia me nā laina ʻelua ʻāpana, i kapa ʻia he uila ʻelua-phase no ka pōkole. I loko o ka uila ʻelua-phase, ua kapa ʻia ka volta ma waena o ka laina ʻāpana he uila uila, maʻamau 380 volts.

ʻO ka ʻokoʻa, ʻo ka volta o ka uila uila hoʻokahi-phase ʻo ia ka volta ma waena o ka laina pae a me ka laina zero, i kapa ʻia ʻo ka voltage phase. I nā ʻoihana ʻenehana a me nā mea pono hale, e like me nā mīkini welding, hoʻohana nui ʻia ka uila ʻelua.

I ka hōʻuluʻulu ʻana, ʻo ka ʻokoʻa nui ma waena o ka uila hoʻokahi-phase a me ʻelua-phase uila ke ʻano a me ka volta o ka lawe ʻana i ka ikehu uila. ʻO ka uila hoʻokahi-phase kahi laina laina a me kahi laina zero, kahi kūpono no ka ʻohana a me ke keʻena ʻoihana me ka volts o 220 volts. ʻO ka lako mana ʻelua-phase he ʻelua laina laina, kūpono no ka ʻoihana a me nā mea pono hale kūikawā me ka volta o 380 volts.

ʻO ka lako mana hoʻokahi-phase: pili maʻamau i kēlā me kēia laina laina (i ʻike ʻia ʻo ka laina ahi) ma 380V ʻekolu-phase a me ʻehā-laina AC mana. ʻO ka volta he 220V. Ana ʻia ka laina ʻāpana me kahi peni uila haʻahaʻa haʻahaʻa maʻamau. ʻO ka ikehu maʻamau i ke ola. ʻO ka pae hoʻokahi kekahi o nā laina ʻekolu i ka laina ʻaʻohe. Ua kapa pinepine ʻia ʻo "laina ahi" a me "laina zero". E pili ana i ka mana 220V a me 50Hz AC. Ua kapa ʻia ka ʻepekema ʻenehana uila hoʻokahi "phase voltage".
ʻEkolu-phase mana lako: ʻO ka lako mana i haku ʻia me ka alapine like o ʻekolu mau alapine a me nā amplitudes like, a ʻo ka māhele o ka mana AC i haku ʻia me 120 degere o ka ʻeke uila i kapa ʻia he ʻekolu-phase AC mana lako. Hoʻokumu ʻia ia e kahi mea hana AC ʻekolu-phase. Hāʻawi ʻia ka mana AC hoʻokahi-phase i hoʻohana ʻia i kēlā me kēia lā e kahi ʻāpana o ka mana AC ʻekolu-phase. ʻO ka lako mana AC hoʻokahi-phase i hoʻopuka ʻia e kahi mea hana hoʻokahi-phase i hoʻohana ʻole ʻia.

ʻO ka ʻokoʻa ma waena o ka mana hoʻokahi-phase a me ʻekolu-phase mana lako ʻo ia ka mana o ka mana mai ka generator he ʻekolu-phase. Hiki i kēlā me kēia māhele o ka mana mana ʻekolu-phase ke hana i kahi kaapuni hoʻokahi-phase e hāʻawi i nā mea hoʻohana i ka ikehu mana. ʻO ka ʻōlelo maʻalahi, aia ʻekolu laina ʻāpana (laina ahi) a me kahi laina ʻole (a i ʻole laina waena), a i kekahi manawa ʻekolu mau laina pae wale nō e hoʻohana ʻia. ʻO ka volta ma waena o ka laina pae a me ka laina ʻāpana he 380 volt, a ʻo ka volta ma waena o nā laina pae a me ka laina zero he 220 volts. Hoʻokahi wale nō laina o ke ahi a me kahi uea ʻole, a ʻo ka volta ma waena o lākou he 220 volts. ʻO ka uila AC ʻekolu-phase ka hui pū ʻana o ka mana AC hoʻokahi-phase me ka amplitude like, ke alapine like, a me ka ʻokoʻa 120 °. ʻO ka uila ʻāpana hoʻokahi ka hui ʻana o kekahi laina pae a me ka laina ʻole i ka uila ʻekolu-phase.

He aha nā pōmaikaʻi o lāua? He nui nā pono o ka mana AC ʻekolu-phase ma mua o ka mana AC hoʻokahi. Loaʻa iā ia ke kūlana kiʻekiʻe ma ke ʻano o ka hana mana, ka lawe ʻana a me ka hāʻawi ʻana, a me ka hoʻololi ʻana i ka ikehu uila i ka ikehu mechanical. No ka laʻana: hana ʻia nā mea hana ʻekolu-phase a me nā mea hoʻololi ma mua o nā mea hana hoʻokahi-phase me ka mana like a me nā mea mālama waiwai, a maʻalahi lākou i ke ʻano a me ka hana maikaʻi loa. 50% o ka nui. I ka hihia o ka lawe ʻana i ka mana like, hiki i nā uea hoʻoili ʻekolu-phase ke hoʻopakele i ka 25% o nā metala non-ferrous ma mua o nā uea hoʻoili hoʻokahi-phase, a ʻoi aku ka liʻiliʻi o ka ikehu uila ma mua o ka lawe ʻana i hoʻokahi-phase.
