ʻEkolu Māhele Hoʻohui Hui Pū ʻia Jacket Zinc Oxide Arrester

Nānā nui

ʻO ka metal oxide arrester (MOA) kahi mea pale koʻikoʻi i hoʻohana ʻia no ka pale ʻana i ka insulation o ka hoʻoili mana a me nā mea hoʻololi mai nā pōʻino overvoltage.Loaʻa iā ia ka pane wikiwiki, nā hiʻohiʻona volt-ampere paʻa, ka hana paʻa, ka mana nui o kēia manawa, ke koena haʻahaʻa haʻahaʻa, a me ke ola lōʻihi., ka hana maʻalahi a me nā pono ʻē aʻe, hoʻohana nui ʻia i ka hana mana, ka hoʻouna ʻana, substation, ka hāʻawi ʻana a me nā ʻōnaehana ʻē aʻe.Hana ʻia ka mea hoʻopaʻa paʻa metala metala me ka silicone rubber composite material.Ke hoʻohālikelike ʻia me ka pahu hopu porcelain kuʻuna, loaʻa iā ia nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka paʻa paʻa, ke kūpaʻa pollution ikaika, a me ka hana pahū maikaʻi.Aia ka mea hopu ma lalo o ka uila hana maʻamau, ʻo ka mea e kahe ana ma o ka mea hopu he microampere wale nō.Ke hoʻokau ʻia i ka overvoltage, ma muli o ka nonlinearity o ke kūpaʻa zinc oxide, ʻo ke kahe e kahe ana ma o ka arrester hiki koke i nā tausani amperes, a aia ka mea hopu i ke kūlana alakaʻi.E hoʻokuʻu i ka ikehu overvoltage, no laila e kaupalena pono i ka pōʻino o ka overvoltage i ka hoʻoili mana a me nā mea hoʻololi.

ʻO ka pahu hopu zinc oxide i hoʻohui ʻia ʻekolu-phase he ʻano mea pale hou i hoʻohana ʻia no ka pale ʻana i ka insulation o nā lako mana mai nā pōʻino overvoltage.Hoʻopaʻa ia i ka overvoltage o ka pae-a-ʻāina me ka hoʻopaʻa pono ʻana i ka overvoltage o ka phase-to-phase.Hoʻohana nui ʻia no ka pale ʻana i nā mea hoʻololi a me nā mīkini uila, nā capacitors uku like, nā mea kanu mana, nā substations, a me nā mea ʻē aʻe. ma waena o nā pae.Hoʻohana ka surge arrester i ka nui o ka zinc oxide resistors e like me ka mea nui, nona nā hiʻohiʻona volt-ampere maikaʻi a me ka hiki ke komo i ka overvoltage, a hāʻawi i ka palekana hilinaʻi no nā lako pale.Ua hoʻohana nui ʻia i nā ʻōnaehana mana.
