Ina paha o ke keena uwea o anmea hoʻoheheʻe uila pahūpono ka noi pena insulating ma muli o ka loiloi piha o ke ʻano pahū-hōʻoia kikoʻī, nā koi maʻamau, a me nā hiʻohiʻona noi maoli.
I. Nā Koina Koʻikoʻi o nā Kūlana Kūlana
1. GB 3836.1-2021 (Nā Kona Nui no nā Lako i nā Lewa Pahū)
Hoʻopili kēia maʻamau i nā koi no nā kaiapuni lepo akā ʻaʻole ia e hoʻokau i nā lula koi i ka hoʻoheheʻe ʻia ʻana o ka insulation varnish i loko o nā keʻena uila no nā lako papa II (e like menā mea hoʻomehana uila pahū).
No nā lako Papa I (nā mines lanahu ma lalo o ka honua), pono e uhi ʻia nā ʻili o loko o nā keʻena uwea metala me ka pena arc-resistant (e like me 1320 epoxy porcelain pena) i mea e pale ai i nā pahū kinoea. Eia nō naʻe, ʻaʻohe koi kikoʻī i ʻōlelo ʻia no nā lako papa II (nā wahi eli lanahu ʻole e like me nā mea kanu kemika, nā ʻaila a me nā ʻenehana, etc.).
2. Hoʻolālā Kūikawā o nā Lako Paʻa Paʻa (Ex d).
Pono e hoʻopaʻa ʻia nā ʻili o ka pā ahi i ka phosphating a uhi ʻia me ka ʻaila anti-rust (e like me 204-1 anti-rust oil) i mea e hōʻoia ai i ka sila a me ka pale ʻana i ka corrosion. ʻOiai loaʻa i ka ʻaila anti-rust kekahi mau waiwai insulating, ʻaʻole ia he pena insulating kūikawā.
Inā loaʻa nā mea alakaʻi i ʻike ʻia a i ʻole nā pilikia uila i loko o ke keʻena uwea, pono ka hoʻolālā e hoʻokō me nā maʻamau (e laʻa, GB/T 16935.1) ma o ka hoʻomaʻemaʻe a me ka mamao kolo, ma mua o ka hilinaʻi wale ʻana i ka insulating varnish.
3. Nā Koina Insulation no ka Hoʻonui i ka palekana (Ex e) Mea Hana
Pono nā lako palekana hoʻonui e hōʻoia i ka ʻole o nā huna ahi i ka wā o ka hana maʻamau, me ka hilinaʻi nui ʻana o ka hana insulation o kāna keʻena uwila i nā mea insulating (e like me ka ceramics, epoxy resin) a me ka conductor sheathing, ma mua o ka uhi ʻana o ke keʻena.
Inā ʻino ka ʻili o ka ʻāpana insulating, pono e hoʻoponopono ʻia me ka pena insulating o ka papa like, akā ʻaʻohe koi no ka uhi ʻana o ka lua holoʻokoʻa.
II. Noʻonoʻo ʻenehana i nā noi maʻamau
1. Nā hana a me nā palena o ka Insulating Varnish
Pōmaikaʻi: Hiki i ka pena insulating ke hoʻonui i ka ikaika o ka ʻili o ka ʻili (e like me ke kūpaʻa arc a me ka pale ʻana i ka leakage), e kūpono loa ia no ka haʻahaʻa kiʻekiʻe a i ʻole ka lepo lepo. No ka laʻana, hiki i ka hoʻohana ʻana i ka 20-30μm o ka pena epoxy insulating hiki ke hoʻonui i ka nui o ka paʻa ʻana o ka insulation ma luna o 85%.
Pilikia: Hoʻopilikia paha ka pena insulating i ka hemo ʻana o ka wela. No ka laʻana, he pahū-palemea puhi uilahoʻopololei i ka hoʻoheheʻe ʻana o ka wela ma o nā puka hoʻoluʻu a me ka hoʻopiha ʻana i ke kinoea inert. Hiki ke hoʻopau i ke koena wela o ka hoʻopā nui ʻana. Eia hou, pono e hele ka pena insulating i nā ho'āʻo kūʻē i ka wela kiʻekiʻe (e laʻa, ma luna o 150°C) a i ʻole hiki ke hāʻule.
2. Nā Hana Hana Hana a me nā Hana Hana Hana
ʻO nā lako pale lepo kahiko: Hoʻohana ka hapa nui o nā mea hana i kahi kumu pale-pale (e laʻa, C06-1 hao ʻulaʻula alkyd primer) i loko o ke keʻena uwea, akā ʻaʻole koi ʻia ka pena insulating. No ka laʻana, hoʻohana kekahi pahu pahu pahu pahu pahū i kahi hui "primer + arc-resistant magnetic paint", e hoʻoikaika ana i ka insulation ma ka wahi hope wale nō.
Hoʻonui ʻia nā lako palekana: Hoʻonui ʻia ka manaʻo nui i ka hilinaʻi mechanical o nā pilina conductor (e like me nā anti-loosening terminals) a me ke koho ʻana i nā mea insulating, ʻoiai ʻaʻole pono ka hoʻoulu ʻana i ka lua.
3. Nā Koina Hou no nā Kūlana Kūikawā
Kaiapuni kiʻekiʻe-corrosion (e like me ke kahakai a i ʻole nā wahi ʻoihana kemika): E hoʻopili i ka pena anti-corrosion insulating (e like me ka ZS-1091 ceramic insulating coating) no ka hōʻoia ʻana i ka pale kemika a me ka insulation.
Nā lako uila kiʻekiʻe (e laʻa, ma luna o 10kV): Pono e hoʻopili ʻia ka pena anti-corona mānoanoa-gradient no ka hoʻopau ʻana i nā hoʻokuʻu hapa.
III. Manaʻo a me nā manaʻo
1. Nā hiʻohiʻona hoʻoheheʻe ʻia
ʻO nā keʻena uwea wale nō o nā lako Papa I (no nā mines lanahu lalo) pono e uhi pono ʻia me ka pena pale-arc.
Inā hoʻonui ka mea hana i kāna hana pahū ma o ka hoʻohana ʻana i ka pena insulating (e laʻa, no ka hoʻokō ʻana i nā helu IP kiʻekiʻe a i ʻole ka pale ʻana i ka corrosion), pono e hōʻike maopopo ʻia kēia ma nā palapala hōʻoia.
2. ʻAʻole koi ʻia akā ʻōlelo ʻia nā hiʻohiʻona
No nā mea hana papa II, pono e hoʻopili i ka pena insulating inā loaʻa nā kūlana aʻe:
ʻO ke keʻena uwea he wahi paʻa, me ka mamao o ka uila a i ʻole ka mamao creepage e kokoke ana i ka palena maʻamau.
ʻO ka haʻahaʻa haʻahaʻa kiʻekiʻe (e laʻa, RH > 90%) a i ʻole ka loaʻa ʻana o ka lepo conductive.
Pono nā mea hana i ka hana lōʻihi a paʻakikī ke mālama (e laʻa, kanu ʻia a i hoʻopaʻa ʻia paha).
Manaʻo ʻia e koho i ka pale wela kiʻekiʻe (≥135 ° C) a me ka pena insulating paʻa ikaika (e like me ka pena epoxy polyester), me ka mānoanoa i hoʻomalu ʻia ma waena o 20-30μm e kaulike i ka insulation a me ka wela.
3. Kaʻina hana a me ka hōʻoia
Ma mua o ka pīpī ʻana, pono e hoʻopaʻa ʻia ka lua i ka sandblasting (Sa2.5 grade) e hōʻoia i ka pili ʻana o ke kiʻi pena.
Ma hope o ka pau ʻana, pono e hoʻāʻo ʻia ke kūpaʻa insulation (≥10MΩ) a me ka ikaika dielectric (eg, 1760V/2min), a pono e hoʻoholo ʻia ka hoʻāʻo ʻana o ka paʻakai paʻakai (e laʻa, 5% NaCl solution, 1000 mau hola me ka ʻole o ka ʻōpala).
Inā makemake ʻoe e ʻike hou aku e pili ana i kā mākou huahana, e ʻoluʻolukāhea iā mā˚ou!
