He aha ka mea hopu uila?He aha ke ʻano o ka pale ʻana?ʻO nā mea uila i hana i ka ʻoihana uila

no nā makahiki he nui e ʻike pono i kēia.Akā i ka wā e pili ana i ka ʻokoʻa ma waena o nā mea hopu uila a me ka piʻi ʻana

nā mea pale, ʻaʻole hiki i nā limahana uila ke haʻi iā lākou no kekahi manawa, a ʻo kekahi mau mea hoʻomaka uila

huikau hou aku.Ua ʻike mākou a pau e hoʻohana ʻia nā mea hopu uila no ka pale ʻana i nā lako uila mai ka overvoltage transient kiʻekiʻe

nā pōʻino i ka wā o ka uila, a e kaupalena i ka manawa kaʻa kaʻa a hoʻopaʻa pinepine i ka amplitude freewheeling.Uila

ʻO nā mea hopu i kekahi manawa i kapa ʻia ʻo nā mea pale overvoltage a me nā palena overvoltage.

ʻO ka mea pale pale, i ʻike ʻia ʻo ka pale uila, he mea uila e hāʻawi i ka pale palekana no

nā lako uila like ʻole, nā mea kani, a me nā laina kamaʻilio.Ke hiki koke mai ke au kiʻekiʻe a i ʻole ka uila

i loko o ke kaapuni uila a i ʻole laina kamaʻilio ma muli o ke keakea o waho, hiki iā ia ke hana i kahi shunt i ka manawa pōkole loa

pale i ka pōʻino nui o nā mea hana ʻē aʻe ma ke kaapuni.No laila, he aha ka ʻokoʻa ma waena o ka mea hopu uila a me ka piʻi

mea hoomalu?Ma lalo nei mākou e hoʻohālikelike i nā ʻokoʻa nui ʻelima ma waena o nā mea hopu uila a me nā pale pale, no laila ʻoe

hiki ke hoʻomaopopo pono i nā hana o nā mea hopu uila a me ka pale pale.Ma hope o ka heluhelu ʻana i kēia ʻatikala,

Manaʻo wau e hāʻawi i nā limahana uila i ka ʻike hohonu o nā mea hopu uila a me nā pale pale.

01 ʻO ke kuleana o nā mea pale a me nā mea hopu uila

1. ʻO ka pale pale: Ua kapa ʻia ʻo Surge protector he surge protector, haʻahaʻa-voltage mana lako uila pale uila, uila.

pale, SPD, etc. He mea uila ia e hāʻawi i ka palekana palekana no nā mea uila like ʻole, nā mea kani,

a me nā laina kamaʻilio.He mea uila ia e hāʻawi i ka palekana palekana no nā mea uila like ʻole,

nā mea kani, a me nā laina kamaʻilio.Ke hiki koke mai ke au kiʻekiʻe a i ʻole ka uila ma kahi kaapuni uila a i ʻole

laina kamaʻilio ma muli o ke keakea o waho, hiki i ka mea pale pale ke alakaʻi a hoʻokuʻu i ke au i ka manawa pōkole loa,

no laila e pale ana i ka piʻi ʻana mai ka hōʻino ʻana i nā mea hana ʻē aʻe o ke kaapuni.

Ma waho aʻe o ka hoʻohana ʻia ʻana i ke kahua mana, pono pū nā mea pale surge i nā kahua ʻē aʻe.Ma keʻano he mea pale, lākou

e hōʻoia i ka hoʻemi ʻana o nā mea hana i ka hopena o nā piʻi i ka wā o ke kaʻina pili.

2. ʻO ka mea hoʻopaʻa uila: ʻO ka mea hopu uila he mea pale uila i hoʻohana ʻia no ka pale ʻana i nā lako uila mai nā pōʻino.

o ka overvoltage transient kiʻekiʻe i ka wā o ka uila, a e kaupalena i ka manawa kaʻa kaʻa a hoʻopaʻa i ka amplitude freewheeling.

Ua kapa ʻia ka mea hopu uila i kekahi manawa he over-voltage arrester.

ʻO ka mea hopu uila he mea uila e hiki ai ke hoʻokuʻu i ka uila a i ʻole ka overvoltage i ka wā e hana ai ka ʻōnaehana mana.

pale i nā lako uila mai nā pōʻino overvoltage koke, a ʻoki i ka freewheeling e pale aku i ka hoʻokumu ʻana o ka ʻōnaehana

kaapuni pokole.He mea hana i hoʻopili ʻia ma waena o ka mea hoʻokele a me ka honua e pale aku i ka uila, maʻamau e like me ka

mea i hoomaluia.Hiki i nā mea hopu uila ke pale pono i nā lako mana.I ka manawa e puka mai ai ka volta maʻamau, ka mea hopu

e hana a pāʻani i kahi hana pale.Ke maʻamau ka waiwai o ka volta, e hoʻi koke ka mea hopu i kona kūlana mua e hōʻoia

ka mana maʻamau o ka pūnaewele.

Hiki ke hoʻohana ʻia nā mea hopu uila ʻaʻole wale no ka pale ʻana i nā volta kiʻekiʻe o ka lewa, akā no ka hana ʻana i nā volta kiʻekiʻe.

Inā he hekili, hiki mai ka uila kiʻekiʻe ma muli o ka uila a me ka hekili, a pilikia paha nā mea uila.

I kēia manawa, e hana ka mea hopu uila e pale i nā mea uila mai ka pōʻino.ʻO ka mea nui a nui loa

ʻO ka hana a ka mea hoʻopaʻa uila, ʻo ia ke kaupalena i ka overvoltage no ka pale ʻana i nā lako uila.

ʻO ka mea hopu uila he mea ia e hiki ai i ka uila ke kahe i ka honua a pale i ka hana uila

uila kiʻekiʻe.ʻO nā ʻano nui nā mea hopu-type tube, valve-type arresters, a me zinc oxide arresters.ʻO nā loina hana nui

ʻokoʻa kēlā me kēia ʻano mea hopu uila, akā ʻo kā lākou ʻano hana like, ʻo ia ka pale ʻana i nā lako uila mai ka pōʻino.

02 ʻO ka ʻokoʻa ma waena o nā mea hopu uila a me nā mea pale pale

1. ʻOkoʻa nā pae voltage pili

ʻO ka mea hoʻopaʻa uila: Loaʻa i nā mea hopu uila nā pae uila he nui, mai ka 0.38KV haʻahaʻa haʻahaʻa a hiki i ka 500KV ultra-high voltage;

Mea pale pale: He mau huahana haʻahaʻa haʻahaʻa me nā pae uila he nui e hoʻomaka ana mai AC 1000V a me DC 1500V.

2. He ʻokoʻa nā ʻōnaehana i kau ʻia

ʻO ka mea hopu uila: hoʻokomo pinepine ʻia ma ka ʻōnaehana mua e pale i ke komo pololei ʻana o nā nalu uila;

Surge protector: Hoʻokomo ʻia ma ka ʻōnaehana lua, he ana hoʻohui ia ma hope o ka hoʻopau ʻana o ka mea hopu i ke komo pololei.

o na ale uwila, a i ole ke hoopau ole ka mea hopu i na ale uwila.

3. He okoa ka wahi hoonoho

Uila hopu: Hoʻokomo pinepine ʻia ma ke keʻena kiʻekiʻe-voltage i mua o ka mea hoʻololi (hoʻokomo pinepine ʻia i ke kaapuni e hiki mai ana.

a i ʻole kaapuni i waho o ke keʻena puʻupuʻu kiʻekiʻe-voltage, ʻo ia hoʻi, i mua o ka transformer);

Ka pale pale: Hoʻokomo ʻia ʻo SPD i loko o ke keʻena puʻupuʻu haʻahaʻa haʻahaʻa ma hope o ka mea hoʻololi (hoʻokomo pinepine ʻia ma ke komo o ka

keena hoʻohele haʻahaʻa haʻahaʻa, ʻo ia hoʻi, ka puka o ka transformer).

4. Nā hiʻohiʻona likeʻole a me ka nui

Uila hopu: No ka mea, ua pili ia i ka uila'ōnaehana kumu, pono e lawa i waho hana insulation

a me ka hiʻona nui;

Ka pale pale: No ka mea pili ia i kahi ʻōnaehana haʻahaʻa haʻahaʻa, hiki ke liʻiliʻi loa.

5. Nā ʻano hana hoʻokumu ʻokoʻa

ʻO ka mea hoʻopaʻa uila: ma ke ʻano he kumu hoʻokumu pololei;

Ka pale pale: pili ʻo SPD i ka laina PE.
