ʻO ke kūpaʻa insulation o kahi kaʻa he mea nui ia no ka loiloi ʻana i kāna hana insulation, pili pono i ka hana palekana o ka kaʻa. Ma muli o nā ʻano like ʻole a me nā pae voltage o nā kaʻa, ʻokoʻa nā kūlana haʻahaʻa no ke kūpaʻa insulation.
ʻO ke kūpaʻa ʻana o nā motika haʻahaʻa haʻahaʻa
No ka mea kaʻa uila haʻahaʻas me nā pae uila o 400V a ma lalo, ʻo nā kūlana haʻahaʻa no ka pale ʻana i ka insulation penei:
ʻO nā laina hou i kau ʻia: ʻAʻole pono e emi ka pale ʻana ma waena o nā laina a ma waena o nā laina a me ka lepo ma lalo o 0.5 megohms.
ʻO nā lako a me nā laina e hana ana: ʻAʻole pono ke kū i ka insulation ma lalo o 1 megohm/kilovolt, a i ʻole like me 1 kiloohm/volt.
ʻO ke kū'ēʻana o nā motika liʻiliʻi a me ka nui
No nā mīkini liʻiliʻi liʻiliʻi a liʻiliʻi, ʻo ka palena haʻahaʻa no ka pale ʻana i ka insulation ʻaʻole i emi iho ma mua o 0.5 megohms. Pili kēia maʻamau i nā mea hana a me nā laina i ka hana ʻana, a ʻaʻole pono e emi ka pale insulation ma mua o 1MΩ/kV.
Ke kū'ē kū'ē ouila uila kiʻekiʻes
ʻOi aku ka paʻakikī o nā koi kūʻē insulation no nā motika kiʻekiʻe. ʻO nā kūlana kiko'ī penei:
ʻO ke kūpaʻa insulation stator: Ma ka mahana hana, ʻaʻole pono e emi ka pale insulation ma mua o 1 megohm no ka kilovolt.
ʻAʻole pono e emi iho kona pale ʻana ma mua o 0.5 megohms no ka kilovolt.
Ke ana o ke kuʻekuʻe ʻana o ke kaʻa
Ke ana maoli nei i ka pale insulation o kahi kaʻa, aia kekahi mau ʻokoʻa ma muli o ke kuhikuhi ʻana o nā kūlana like ʻole a me ka mana o nā mea e like me ka mahana a me ka ratio absorption. ʻOi loa inā kokoke ka waiwai kūʻē insulation a me ka ratio absorption i ka waiwai koʻikoʻi, ʻokoʻa paha nā hopena hōʻike o nā mea hana like ʻole. No laila, i ke ana ʻana, pono e hoʻokō pono ʻia nā lula pili, pono ke koho ʻia ka mea pono kūpono, a e hoʻokaʻawale ʻia nā koi palena ʻokoʻa no ke anuanu a me ka wela.
I ka hōʻuluʻulu ʻana, ʻo ka palena haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa o ke kaʻa e pili ana i kona pae uila a me kona ʻano. ʻO ke kūpaʻa insulation o nā kaʻa haʻahaʻa haʻahaʻa a me nā mīkini liʻiliʻi a me waena /mīkini hoʻokomo uila uila ʻAʻole pono e emi iho ma lalo o 0.5 megohms, ʻoiai ʻo ka pale ʻana o ka insulation o nā motika kiʻekiʻe-volt ʻaʻole pono e emi iho ma mua o 1 megohm no ka kilovolt. Kuhi ʻia kēia mau kūlana e hōʻoia ʻaʻole e hoʻokau ka kaʻa i nā pōʻino palekana ma muli o ka lawa ʻole o ka insulation i ka wā o ka hana.
