ʻO LV Surge Ar hopu i ka hana kūʻē i ka uila
ʻO ka poʻe hopu i ka ʻenekini kūʻē i ka uila
Hōʻike o ke kau ʻana
Aia nā pūnaewele i nā keʻena (nā lako kamepiula, nā uila, a me nā pono hoʻomehana), kahi kia kia (ke ahi ahi, ka mea ʻaihue ʻaihue, kaohi komo, ka nānā wikiō ʻana) a ʻekolu mau hale no ke kaʻina hana ma 10 hectares i ka ʻĀina ʻo Avignon o Palani (ʻo ka likelika o ka uila he 2 hahau i kēlā me kēia km2 i kēlā me kēia makahiki).
ʻO LV Surge Ar hopu i ka hana kūʻē i ka uila
Aia nā kumu lāʻau a me nā mea hao (pylons) ma kahi o ka pūnaewele. Hoʻokomo ʻia nā hale āpau me nā alakaʻi uila. Aia nā lako lako MV a me LV i lalo o ka honua.
Hōʻike 1 - Ke kiʻina hoʻonohonoho no kekahi mau mea hopu i ka wai i cascade
Nā pilikia i kū ʻia
Ua hōʻeha kahi ʻino i ka pūnaewele, e luku ana i ka hoʻonohonoho LV i ka palekana a me ke kumu 36.5 kE o nā pohō hana. ʻO ka hiki ʻana o nā alakaʻi uila i pale i ka hanana mai ke kiʻi ʻana i ke ahi, akā ʻo nā lako uila i wāwahi ʻia ʻaʻole i pale ʻia e nā poʻe hopu pio, kūʻē i ka ʻōlelo aʻoaʻo ma nā hae UTE C-15443 a me IEC 62305.
Ma hope o ke kālailai ʻana i ka equipotentiality a me ka lepo o ka ʻōnaehana mana, a ukali ʻia e ka hōʻoia o ke kau ʻana o nā alakaʻi uila a me ka nānā ʻana i nā waiwai o nā uila uila o ka honua, ua hoʻoholo ʻia e hoʻouka i nā mea hopu pio.
Hoʻokomo ʻia nā mea hopu i ka poʻomanaʻo ma ke poʻo o ka hoʻonoho ʻana (ka papa hāʻawi LV nui) a i ka pahu i kēlā me kēia hale hana (e nānā i ke kiʻi 1 ma luna). ʻOiai ʻo ka pili pili kūlike ʻole ka TNC, e hāʻawi wale ʻia ka pale ma ke ʻano maʻamau (ma waena o nā pae a me PEN).
Kiʻi 2 - ʻO nā mea hopu haʻahaʻa uila haʻahaʻa
Hōʻike 2 - SPD ʻAno 2 a me 3 - Ka pale o ka uila nui kūpikipiki / kuewa
- In (8 / 20µs) mai 5 kA a i 60 kA
- Imax (8 / 20µs) mai 10 kA a i 100 kA
- Up mai ka 1 kV a i ka 2,5 kV
- Uc = 275V, 320V, 385V, 440V, 600V
- 1P i 4P, 1 + 1 a i 3 + 1
- Monoblock a pluggable
- TT, TNS, IT
- Hoʻokaʻaʻike hoʻololi loli
I kulike ai me ke alakaʻi UTE C-15443 e pili ana i ka hana i ke alo o nā alakaʻi uila, nā ʻano o ka LSP (Arrester Electric) SPDs SLP40 a me nā mea hopu pio FLP7 penei:
- I ke poʻo o ka hoʻokomo
In = 20 kA, Imax = 50 kA, Up = 1,8 kV - I ka cascade (ma ka liʻiliʻi 10 m ke kaʻawale)
In = 10 kA, Imax = 20 kA, Up = 1,0 kV
I ka cascade, hāʻawi ʻia kahi pale maikaʻi no nā papa hoʻoili lua (nā keʻena a me ka pou palekana).
E like me ka hoʻohuli ʻia ʻana o ka pilina kiko i TNS, pono e hāʻawi ʻia ka pale ma ke ʻano maʻamau (ma waena o ka pae a me ka PE) a me ke ʻano hoʻokaʻawale (ma waena o nā pae a me ka kūlike ʻole). ʻO nā hāmeʻa hoʻokaʻawale, i kēia hihia, he mau haki kaapuni me ka hiki naha o 22 KA.
Aʻo // E hoʻouka nei i kahi pale pale
Hōʻike ka Video i ka hoʻonohonoho pololei ʻana o ka pale lū, ke hui pū nei me ka pale pale (breaker circuit). ʻO ka "50 cm pili lula ”wehewehe e kōkua iā ʻoe e hoʻomaopopo i ka hoʻopili pono ʻana e like me ka standard IEC 60364-5-534.
