He aha ka ʻokoʻa ma waena o ka mea hoʻoheheʻe kaapuni i hoʻoheheʻe ʻia a me ka mea hoʻoheheʻe kaapuni ea?

ʻO kakaapuni kaapuni eapili i ke kaapuni, hoʻokaʻawale a lawe i ke au hana i helu ʻia a me nā au hewa maʻamau e like me ka hewa pōkole a me ka pale o ka ukana.mālama.ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa nā mea haʻihaʻi kaapuni ea, ʻo ia hoʻi, ʻo 1Kv ka helu hana maʻamau a ma lalo.ʻO ka mea haʻihaʻi kaapuni ea he mea hoʻololi mana me nā hana mālama he nui e hiki ke ʻoki a hoʻohui i nā kaapuni i ka manawa i helu ʻia a me ka helu hana o kēia manawa.ʻO ke ʻano o kāna hana mālama a me ke ʻano o ka pale ʻana e koho ʻia e ka mea kūʻai.E like me ka overcurrent protection, overcurrent protection, operation, undervoltage, etc. ʻO nā ʻano mua ʻelua o ka mālama ʻana ʻo ia ka hoʻonohonoho kumu o ka mea hoʻokele kaapuni ea, a ʻo nā mea hope ʻelua he koho.No laila, hiki nō hoʻi i nā mea haʻihaʻi ea ke wehe i nā kaapuni uila i nā kūlana hewa maʻamau (hoʻouka i ka hewa pōkole, hoʻouka i ka overcurrent, ka uila haʻahaʻa, etc.).ʻO kapahu pahu plastik kaapuniHiki iā r ke hoʻokaʻawale i kēia manawa, i ka wā o ka overload o kēia manawa a me ka hewa pōkole, hiki iā ia ke wehe a ʻoki i ka mana.ʻO ka pahu pahu pahu pahu plastik e pili ana i ka pahu metala o nā mea hana, i hoʻohana ʻia no ka pale ʻana i ka waena o ka mea hoʻokele uila a me ka mea paʻa o ka mea metala.Loaʻa ka ʻōnaehana wela, ka ʻōnaehana magnetic, a me nā hopena ʻōnaehana wela: inā ʻoi aku ka nui o ke au ma mua o ka nui o ka mana i koi ʻia e ka maʻamau aupuni, e wela a hoʻopōʻino ka mea wela i ke gula pālua, e hoʻoneʻe a hoʻonui i ke kūlana o ka ʻiʻo.Hoʻokaʻawale, me ka hopena pale overvoltage;ʻO ka hopena o ka ʻōnaehana magnetic: Ke ʻoi aku ka nui o kēia manawa i ka mana pōkole e koi ʻia e ka maʻamau aupuni, e hoʻopuka ka electromagnetic coil i loko o ka ʻōnaehana magnetic i kahi flux magnetic nui loa, a i ka wā e ʻoi aku ai ka ikaika i hoʻokumu ʻia e ka magnetic flux ma mua o ka torsion core transformer. ʻO ka ikaika axial o ka pūnāwai, ʻo ka mea hoʻololi ikaika i ka ʻōnaehana magnetic e hoʻoikaika i ke kūlana kaulahao liʻiliʻi, e hāpai ke kaulahao liʻiliʻi i ke kūlana pani pani, e haki ka rocker, a ʻike i ka pale o ka overcurrent.Ma ka ʻōlelo ākea, ʻo nā mea haʻihaʻi kaapuni ea e pili ana: nā mea haki kaapuni frame, nā mea hoʻoheheʻe kaapuni i hoʻoheheʻe ʻia, a me nā mea wāwahi kaapuni liʻiliʻi.ʻEkolu puka ma luna o ka pahu plastik isolating switch, i hoʻopili ʻia i ʻekolu-phase uila (ʻoiaʻiʻo 380V), i hoʻohana ʻia no ka ʻōnaehana hoʻoili mana hana ʻenehana a me nā polokalamu ʻōnaehana pale kaʻa;ʻO ka hoʻololi hoʻokaʻawale i hoʻohana ʻia i nā hale e pili ana i ka pae hoʻokahi (ʻoiaʻiʻo 220V), i hoʻohana ʻia no ka hana ʻenehana o nā ʻōnaehana hoʻoili mana a me nā polokalamu ʻōnaehana pale kaʻa.Ka mālama ʻana i nā lako hāʻawi mana no nā mea hana ʻenehana uila.No laila, aia ʻekolu mau puka ma ka pahu plastik isolating switch, ʻaʻole hiki ke hoʻohana ʻia no ka hoʻohana ʻana i ka home.
