Pahū ʻo Shenhai
Pono nā ea hoʻoheheʻe pahū i ka hoʻohana ʻana i nā mea insulation maikaʻi loa e hōʻoiaʻiʻo i kā lākou hana he palekana a hilinaʻi.. ʻO ka maʻamau, Hoʻokaʻawale ʻia nā mea insulation i ʻekolu mau ʻano: kinoea, wai wai, a paa. Hoʻohana ʻia nā insulators kinoea ma lalo o nā kūlana kiʻekiʻe, wai insulators nui e like me ka aila mineral ma haʻahaʻa-voltage transformers, ʻoiai ua hoʻohana nui ʻia nā insulators paʻa i nā ʻāpana insulation o nā mea uila.
ʻO nā mea e pono ai no nā mea hoʻonā:
1. Pono e loaʻa nā insulators paʻa ʻaʻole hiki ke hoʻopau ʻia a me ka pale ahi.
2. Pono nā insulators paʻa hōʻike i ka liʻiliʻi o ka moisture absorption.
3. ʻO nā insulators paʻa pono e kū'ē i nā arcs uila.
4. Pono nā insulators paʻa hōʻike i ka pale wela maikaʻi loa.
ʻO ke kūpaʻa wela o ka insulation paʻa e hōʻike ana i ka mahana wela kahi e hiki ai i kēia mau mea ke hana i nā manawa lōʻihi me ka ʻole o ka pōʻino. Pono nā insulators paʻa e mālama i nā waiwai mechanical ikaika ke ʻoi aku ka mahana ma mua o 20.0 ℃ a ʻaʻole e hāʻule ma lalo o 80.0 ℃ mai ka mahana hana mau o nā mea hana.. Ke koi nei nā mea uila like ʻole i nā pae like ʻole o ka pale wela.
Hoʻokaʻawale ʻia ka pale wela o nā insulators paʻa i ʻewalu mau papa: Y, A, E, B, F, H, C. ʻO nā mea hana insulating maʻamau ka triazine asbestos arc-resistant plastic a me DMC plastic, me ko lākou paepae paepae ma waena o 130-155 ℃. Hōʻike pū ʻia nā lako uila palekana palekana no ka kaʻa, mea hoʻololi, a me nā makani electromagnet e uhi ʻia me ʻelua mau ʻāpana o ka mea hoʻokaʻawale no nā uea ʻole, ma ka liʻiliʻi hoʻokahi papa no nā uwea i uhi ʻia i ka enamel, a me ke ʻano QZ-2 no nā uea mānoanoa i uhi ʻia i ka enamel.
I ka manawa like, Pono ka wiliwili e hoʻohana i kekahi o nā ʻenehana impregnation: kaiapuni ana, kulu ana, a i ʻole ka impregnation mānoanoa. ʻAʻole pono e hoʻohana ʻia ke ʻano o ka palaki ʻana a me ka pulupulu no ka impregnation. Inā hoʻohana ʻia nā mea hoʻoheheʻe organik ma ke ʻano he impregnants, pono ʻelua pōʻai o ka impregnation a me ka maloʻo. ʻAʻole pāpā ʻia nā wili me nā anawaena ma lalo o 0.25mm no nā lako uila palekana palekana. Ma nā hihia kūikawā, hiki ke hana i na wili palekana i loko a i ʻole nā hale i hoʻopaʻa ʻia.
