pae insulation o ka transformer

Ma keʻano he mea uila koʻikoʻi i ka pūnaewele mana, pili pono ka pae insulation o ka transformer i ka hana palekana a paʻa o ka pūnaewele mana. ʻO ka pae insulation ka hiki o ka mea hoʻololi ke kū i nā overvoltages like ʻole a me ka volta hana lōʻihi i ka wā o ka hana, a he kumu nui ʻaʻole hiki ke nānā ʻole ʻia i ka hoʻolālā, hana, hana a me ka mālama ʻana i ka transformer.

1. Ka wehewehe ʻana o ka pae insulation o ka transformer ʻO ka pae insulation e pili ana i ka hiki o ke ʻano insulation o ka transformer e mālama i ka pono a me ka palekana ke kū ʻo ia i nā overvoltages like ʻole a me nā volta hana lōʻihi. Loaʻa kēia i ka pae voltage hiki ke ʻae ʻia i ka hui pū ʻana me ka mea hoʻopaʻa uila uila a hilinaʻi pololei i ka nui o ka volta Um o nā mea hana.

2. Insulation hale o ka transformer E like me ka insulation pae o ka wili laina hopena a me ka neutral wahi mea like, ka transformer hiki ke maheleia i elua insulation hale: piha insulation a graded insulation. ʻO ka mea hoʻololi me ka hoʻolālā insulation piha ka pae insulation like o ka hopena laina wiliwili a me ke kiko kūʻokoʻa, ʻoi aku ka kiʻekiʻe o ka insulation margin, a kūpono i nā mea hoʻololi me nā pae uila kiʻekiʻe a me nā kaiapuni hana paʻakikī. Hoʻonohonoho ka mea hoʻololi me ka hoʻolālā insulation graded i nā pae insulation like ʻole ma waena o ka hopena laina wili a me ke kiko kūʻokoʻa e like me nā pono maoli e hoʻokō i ka hoʻolālā insulation a hoʻemi i nā kumukūʻai.

3. ʻO ka ho'āʻoʻana i ka pae insulation o ka transformer No ka hōʻoiaʻana i ka hoʻokōʻana o ka insulation level o ka mea hoʻololi i nā koi hoʻolālā, pono keʻano o nā ho'āʻo insulation. No nā mea hoʻololi me ka pae uila o 220kV a ma lalo, he 1 mau minuke mana pinepine e kū i ka hoʻāʻo ʻana i ka volta a me ka hoʻāʻo ʻana i ka volta impulse e hana maʻamau e loiloi i ko lākou ikaika insulation. No nā mea hoʻololi me nā kiʻekiʻe o ka volta kiʻekiʻe, koi ʻia nā hoʻokolohua impulse paʻakikī. I nā hoʻāʻo ʻana o ka hale hana, hoʻokō pinepine ʻia kahi hoʻāʻo kūʻokoʻa voltage ma mua o ʻelua mau manawa o ka volta helu i ka manawa like e loiloi i ka hana insulation o ka insulation nui a me ka insulation longitudinal.

Eia kekahi, ʻo ke ana ʻana i ka pale insulation, absorption ratio a me ka polarization index o ka wili pū me ka bushing he mea nui hoʻi ia e loiloi i ke kūlana insulation holoʻokoʻa o ka transformer. Hiki i kēia mau ana ke ʻike maikaʻi i ka makū holoʻokoʻa o ka insulation transformer, ka lepo a i ʻole ka lepo ma luna o ka ʻili o nā mea, a me nā hemahema o ke komo ʻana.

4. Nā mea e pili ana i ka pae insulation o ka transformer I ka wā o ka hana ʻana o ka transformer, ʻo nā mea e pili ana i ka pae insulation ka nui o ka mahana, ka haʻahaʻa, ke ʻano pale ʻaila a me ka hopena overvoltage. 1) Mahana: ʻO ka wela ke kumu nui e pili ana i ka hana insulation o ka transformer. ʻO ka hana insulation o ka mea insulating e emi iho ana me ka piʻi ʻana o ka mahana, a ʻo ka loaʻa ʻana o ka wai i loko o ka ʻaila e hoʻolōʻihi i ka ʻelemakule o ka insulation. No laila, ʻo ka mālama ʻana i ka mahana hana o ka transformer a me ka mālama ʻana i ke kūlana maikaʻi o ka mea insulating he mau mea koʻikoʻi ia e hoʻomaikaʻi ai i ka pae insulation.

2) Humidity: ʻO ka hele ʻana o ka haʻahaʻa e hoʻolōʻihi i ka ʻelemakule o ka mea insulating a hoʻemi i kāna hana insulation. No laila, i ka wā o ka hana ʻana o ka transformer, pono e hoʻomalu pono ʻia ka haʻahaʻa ambient e pale aku i ka mea insulating mai ka pulu.

3) ʻO ke ʻano pale ʻaila: ʻO nā ʻano pale ʻaila ʻokoʻa nā hopena like ʻole i ka hana insulation. No ka mea ua hoʻokaʻawale ʻia ka ʻili o ka mea hoʻololi i hoʻopaʻa ʻia mai ka lewa, hiki iā ia ke pale pono i ka volatilization a me ka diffusion o CO a me CO2 i loko o ka ʻaila, a laila mālama i ka hana maikaʻi o ka ʻaila insulating.

4) Ka hopena overvoltage: ʻO ka hopena overvoltage kekahi mea nui e pili ana i ka pae insulation o ka transformer. ʻO ka overvoltage uila a me ka overvoltage hana hiki ke hoʻopōʻino i ke ʻano insulation o ka transformer. No laila, i ka hoʻolālā ʻana a me ka hana ʻana i ka transformer, pono e noʻonoʻo pono ʻia ka hopena o ka overvoltage a pono e lawe ʻia nā ʻano pale e pili ana.
