E pili ana i ka wili uila kiʻekiʻe

ʻO ka bushing kiʻekiʻe-voltage e pili ana i kahi mea e hiki ai i hoʻokahi a i ʻole kekahi mau alakaʻi ke hele i nā ʻāpana e like me nā paia a i ʻole nā ​​pahu no ka insulation a me ke kākoʻo, a he mea koʻikoʻi i nā ʻōnaehana mana.I ke kaʻina hana, ka lawe ʻana a me ka mālama ʻana, loaʻa paha i nā bushings kiʻekiʻe-voltage nā hemahema ma muli o nā kumu like ʻole;i ka wā lōʻihi o ka hana ʻana, hoʻopilikia ʻia lākou e nā hopena o ke kahua uila a me ka hoʻomehana conductor, ka pōʻino mechanical a me ka corrosion kemika, a me nā kūlana lewa.E loaʻa nō hoʻi nā hemahema me ka mālie.

Hoʻohana nui ʻia nā bushings kiʻekiʻe no ka hoʻokaʻawale ʻana i ka lepo o nā laina komo a i waho o nā lako mana e like me nā transformers, reactors, a me nā mea hoʻokele kaapuni, a me nā kaʻa kiʻekiʻe-voltage e hele ana i nā paia.ʻEkolu ʻano o nā puʻupuʻu uila kiʻekiʻe: hoʻokahi dielectric bushing, composite dielectric bushing a me capacitive bushing.ʻO ka insulation nui o ka capacitive bushing i haku ʻia me kahi coaxial cylindrical series capacitor bank i hoʻokumu ʻia e ka wili ʻana i nā mea insulating layered a me nā electrodes metala foil alternately ma ke koʻokoʻo conductive.Wahi a nā mea insulating ʻokoʻa, ua hoʻokaʻawale ʻia i ka pepa gummed a me ka aila pepa capacitive bushing.ʻO 110kV a ma luna o ka transformer kiʻekiʻe-volt bushings maʻamau ka aila-pepaʻano capacitor;Hoʻokumu ʻia ia me nā pauku uwila, ke keʻena mālama ʻaila, ka lima porselena luna, ka lima porcelain haʻahaʻa, ka capacitor core, ke koʻokoʻo alakaʻi, ka ʻaila insulating, flange, a me ka pōleʻa kaomi.

I ka wā o ka hana ʻana o ka bushing kiʻekiʻe-voltage, pono ka insulation nui e kū i ka volta kiʻekiʻe, a ʻo ka ʻāpana conductive pono e lawe i kēia manawa nui.ʻO nā hewa nui ka pilina maikaʻi ʻole o nā mea hoʻohui uila i loko a me waho, ka pulu a me ka hōʻino ʻana o ka insulation bushing, ka nele o ka aila i ka bushing, ka hoʻokuʻu ʻana o ka capacitor core a me ka hoʻokuʻu ʻana o ka pale hope i ka honua, etc.

ʻO ka bushing transformer he mea puka e alakaʻi i ka uwea kiʻekiʻe-voltage o ka transformer wili i waho o ka pahu aila, a lawelawe ma ke kākoʻo ʻāpana conductive a me ka insulation honua.I ka wā o ka hana o ka mea hoʻololi, ke hele nei ke au o ka ukana no ka manawa lōʻihi, a ke hele nei ke au pōkole i ka wā e puka ai kahi kaapuni pōkole ma waho o ka transformer.

No laila, loaʻa i ka transformer bushing nā koi aʻe:

Pono e loaʻa ka ikaika uila a me ka ikaika mechanical;

Pono ke kūpaʻa wela maikaʻi a hiki ke kū i ka wela i ka wā pōkole;liʻiliʻi ma ke ʻano, liʻiliʻi i ka nui, a maikaʻi i ka hana sila.

Hoʻokaʻawale

Hiki ke hoʻokaʻawale ʻia nā bushings kiʻekiʻe-voltage i nā bushings piha i ka aila a me nā bushings capacitive.

ʻO ke kaulapepai loko o ka aila-hoopiha bushing mea like me ka equalizing pā ma ka capacitive bushing.ʻO ka capacitor core i loko o ka capacitive bushing he pūʻulu o nā coaxial cylindrical capacitors, a i loko o ka ʻaila piha piha, ʻoi aku ka kiʻekiʻe o ka dielectric mau o ka pepa insulating ma mua o ka ʻaila, hiki ke hōʻemi i ka ikaika o ke kahua ma laila.

Hiki ke hoʻokaʻawale ʻia nā lāʻau ʻaila piha i ka ʻaila ʻaila hoʻokahi a me nā ʻāpana ʻaila nui, a hiki ke hoʻokaʻawale ʻia nā bushings capacitive i nā ʻōpala pepa gummed a hinuhinu.

Hoʻohana ʻia nā lima lima i ka wā e pono ai nā mea lawe i kēia manawa e hele i loko o nā pā metala a i ʻole nā ​​paia ma nā ʻano like ʻole.Wahi a kēia manawa kūpono, hiki ke hoʻokaʻawale ʻia nā bushings i nā bushings transformer, bushings no nā hoʻololi a i ʻole nā ​​mea uila hui pū ʻia, a me nā bushings pā.No kēia hoʻonohonoho electrode "plug-in", ua paʻa loa ke kahua uila ma ka lihi o ka electrode waho (e like me ka flange waena o ka bushing), kahi e hoʻomaka pinepine ai ka hoʻokuʻu.

ʻO ka hoʻohana a me nā ʻano o ka casing

Hoʻohana ʻia nā puʻupuʻu kiʻekiʻe no nā mea hoʻokele uila kiʻekiʻe e hele i nā ʻāpana me nā mana like ʻole (e like me nā paia a me nā pahu metala o nā mea uila) no ka insulation a me ke kākoʻo.Ma muli o ka mahele like ʻole o ka māla uila i loko o ka puʻupuʻu, ʻoi aku ka nui o ke kahua uila i ka lihi o ka ʻaoʻao waena, maʻalahi ka hoʻokuʻu ʻana i ka ʻili.ʻOi aku ka paʻakikī o ka ʻōnaehana insulation kūloko o ka bushing me ke kiʻekiʻe o ka voltage kiʻekiʻe, me ka hoʻohana pinepine ʻana i nā mea insulating i hui pū ʻia, a aia nā pilikia e like me ka wehe ʻana.No laila, pono e hoʻoikaika ʻia ka hoʻāʻo a me ka nānā ʻana o ka pahu.
