I koʻu ʻāina ʻo 3~35KV ʻōnaehana lako mana, ʻo ka hapa nui o lākou he ʻōnaehana kumu ʻole.Wahi a nā lula aupuni, i ka wā e kū ai kahi pae hoʻokahi, ʻae ʻia ka ʻōnaehana e holo me ka hewa no 2 mau hola, e hōʻemi nui ana i ke kumukūʻai hana a hoʻomaikaʻi i ka hilinaʻi o ka ʻōnaehana mana.Eia nō naʻe, ma muli o ka hoʻonui lohi ʻana i ka mana lako o ka ʻōnaehana, ke ʻano o ka mana lako ʻO ka laina ma luna o ke poʻo e hoʻololi mālie ʻia i kahi laina uwea, a e lilo ka capacitance o kēia ʻōnaehana i ka honua i mea nui loa.Ke hoʻopaʻa ʻia ka ʻōnaehana i ka pae hoʻokahi, ʻaʻole maʻalahi ke pio ʻana o ka arc i hana ʻia e ke au capacitive kiʻekiʻe, a hiki ke hoʻololi ʻia i ka honua arc intermittent.I kēia manawa, ʻo ka arc grounding overvoltage a me ka ferromagnetic resonance overvoltage hauʻoli e ia e hoʻoweliweli maoli i ka hana palekana o ka mana mana.I waena o lākou, ʻo ka overvoltage arc-ground hoʻokahi ka mea koʻikoʻi loa, a ʻo ka pae overvoltage o ka pae hewa ʻole hiki ke hiki i 3 a 3.5 mau manawa o ka volta hana maʻamau.Inā hana kēlā ʻano overvoltage kiʻekiʻe ma luna o ka mana mana no kekahi mau hola, e hōʻino paha ia i ka insulation o nā mea uila.Ma hope o nā manawa he nui o ka pōʻino kumulative i ka insulation o nā mea uila, e hoʻokumu ʻia kahi wahi nāwaliwali o ka insulation, kahi e hoʻopilikia ai i ka haki ʻana o ka insulation o ka honua a me ka pōkole pōkole ma waena o nā pae, a i ka manawa like ke kumu i ka haki ʻana o ka insulation o nā mea uila (ʻoi loa. ka insulation breakdown o ke kaʻa) ), ke kelepona pahū ʻana, ka saturation o ka volter transformer hoʻoulu i ka ferromagnetic resonance kino e puhi i lalo, a me ka pahū ʻana o ka mea hopu a me nā pōʻino ʻē aʻe.
