Mea Hoʻopaʻa UilaHe Mea Palekana Uila Koʻikoʻi

ʻO ka mea hoʻopaʻa uila, i ʻike ʻia hoʻi he mea hoʻopaʻa surge, he ʻāpana pale koʻikoʻi ia i nā ʻōnaehana mana uila a me nā kaapuni uila. ʻO kāna hana nui, ʻo ia ke hoʻohuli i nā surges voltage kiʻekiʻe ʻē aʻe—e like me nā mea i hoʻokumu ʻia e nā hahau uila a i ʻole nā ​​​​​​hana hewa o nā lako—mai nā mea koʻikoʻi a palekana i loko o ka lepo, e pale ana i ka pōʻino a i ʻole nā ​​​​​​haki ʻana.

Hana ʻia me nā mea koʻikoʻi, ʻo nā mea pale uila he mea kūʻē ʻole linear (hana pinepine ʻia me ka oxide metala, e like me ka zinc oxide), ʻelua mau electrodes, a me kahi hale insulating. ʻO ka resistor non-linear ka puʻuwai o ka hāmeʻa: he kiʻekiʻe loa kona kūʻē ma lalo o nā voltages hana maʻamau, e hōʻoiaʻiʻo ana ʻaʻohe kahe o ke au pono ʻole a mālama i ka ʻōnaehana mana paʻa. Eia nō naʻe, i ka wā e loaʻa ai kahi voltage surge weliweli, hāʻule koke kona kūʻē, e hana ana i kahi ala haʻahaʻa haʻahaʻa no ke au surge e kāpae i nā lako i hoʻopili ʻia a hoʻokuʻu i ka honua.

Hoʻohana nui ʻia nā mea pale uila ma nā ʻano like ʻole. Ma nā pūnaewele mana, pale lākou i nā mea hoʻololi uila, nā laina hoʻoili, a me nā kikowaena mai nā piʻi uila. Ma nā hale noho a me nā hale kalepa, pale nā ​​​​mea pale liʻiliʻi i nā lako hale, nā ʻōnaehana HVAC, a me nā lako kamaʻilio. ʻOiai ma nā wahi ʻoihana, pale lākou i nā mīkini kikoʻī a me nā ʻōnaehana kaohi mai nā piʻi uila e hiki ke hoʻopilikia i ka hana ʻana.

Hāʻawi nā mea pale uila o kēia wā, ʻoiai nā ʻano metala oxide like ʻole, i nā pono e like me ka nui liʻiliʻi, ʻaʻohe pono no ka mālama mau ʻana, a me ka laulā o ka hoʻohālikelike ʻana o ka voltage. ʻAʻole e like me nā mea pale ʻano gap kahiko, pane wikiwiki lākou i nā surges, e hāʻawi ana i ka palekana hilinaʻi. ʻO ke kau ʻana kūpono—me ka hoʻokumu paʻa ʻana a me nā helu voltage kūlike—he mea nui ia e hōʻoia i ka hana pono ʻana o ka mea pale, e lilo ia i mea palekana koʻikoʻi no ka mālama ʻana i ka hilinaʻi a me ka palekana o nā ʻoihana uila.
