Lae uila a me ka lae paila o ka aila transformer
Nā mea
Nā waiwai maʻamau a me nā hana o ka ʻaila transformer
Pono e loaʻa i ka ʻaila nā waiwai penei:
- ʻO nā hiʻohiʻona dielectric maikaʻi e hōʻoiaʻiʻo ana i ka emi o ka mana.
- ʻO ka resistivity kiʻekiʻe, kahi e hoʻomaikaʻi ai i ka insulation ma waena o nā wili.
- Kiʻekiʻe flash wahi a me ka wela paʻa e hoemi evaporative poho.
- ʻO ke ola lawelawe lōʻihi a me nā hiʻohiʻona ʻelemakule maikaʻi loa ma lalo o nā ukana uila ikaika.
- ʻO ka nele o nā ʻāpana koʻikoʻi i ka haku mele (ma mua o ka sulfur), kahi e pale ai i ka corrosion.
Nā kumu o ka noi:
- Hoʻokaʻawale ma waena o nā wili a me nā ʻāpana conductive ʻē aʻe o kahi transformer.
- Hoʻoluʻu o nā ʻāpana transformer.
- Kāohi i ka oxidation o cellulose mai ka pepa wiliwili insulation.
ʻElua ʻano ʻaila transformer: naphthenic a me paraffinic. Ua hōʻuluʻulu ʻia nā ʻokoʻa ma waena o lākou ma ka papa:
| Nā mea no ka hoʻohālikelike | ʻAila ʻaila | ʻAila paraffin |
| 1. | He haʻahaʻa ka maʻiʻo paraffin/wax | ʻO ka maʻiʻo paraffin/wax kiʻekiʻe |
| 2. | ʻOi aku ka haʻahaʻa o ka ʻaila naphthenic ma mua o ka ʻaila paraffin | ʻOi aku ka kiʻekiʻe o ka ʻaila paraffin ma mua o ka ʻaila naphthenic |
| 3. | ʻOi aku ka maʻalahi o nā aila Naphthenic ma mua o nā aila paraffin. | ʻOi aku ka liʻiliʻi o ka ʻaila paraffin ma mua o ka naphthenic |
| 4. | Hiki ke hoʻoheheʻe ʻia nā huahana oxidation | ʻAʻole hiki ke hoʻoheheʻe ʻia nā huahana oxidation i ka ʻaila |
| 5. | Oxidation o ka paraffin-based crude aila hopena i ka hookumu ana o ka insoluble precipitate e hoonui i ka viscosity. Ke alakaʻi nei kēia i ka hoʻemi ʻana i ka wela, ka wela a hoʻemi i ke ola lawelawe. | ʻOiai ʻoi aku ka maʻalahi o ka ʻaila naphthenic ma mua o ka aila paraffin, hiki ke hoʻoheheʻe ʻia nā huahana hoʻoheheʻe i ka ʻaila. |
| 6. | Loaʻa i nā aila Naphthenic nā pūhui ʻala e mau ana ka wai ma nā wela haʻahaʻa a hiki i -40°C | - |
Ke kiko uila o ka aila transformer
Hōʻike kēia ʻano i ka wela liʻiliʻi kahi e hoʻomaka ai ke kaʻina vaporization.
ʻO nā hana nui o ka ʻaila transformer e hoʻokaʻawale a hoʻomaha i ka transformer. Paʻa kēia ʻaila i nā wela kiʻekiʻe a loaʻa nā waiwai insulating uila maikaʻi loa. ʻO ia ke kumu i hoʻohana ʻia ai kēlā mau ʻaila i nā transformers i mea e hoʻokaʻawale ai i nā ʻāpana lawe i kēia manawa ma lalo o ka volta kiʻekiʻe a e hoʻomaha iā lākou.
ʻO ka loaʻaʻole o ka ukana a iʻole nā poho kaumahaʻole e hoʻonui i ka mahana o ka wili transformer a me ka insulation a puni ka wili. ʻO ka piʻiʻana o ka mahana o kaʻaila ma muli o ka weheʻana i ka wela mai nā makani.
Inā ʻoi aku ka liʻiliʻi o ka ʻaila ʻaila ma lalo o ka maʻamau, a laila e mahuka ka ʻaila, e hana ana i nā kinoea hydrocarbon i loko o ka pahu transformer. I kēia hihia, hele pinepine ka relay Buchholz. He mea pale ia i hoʻokomo ʻia i nā hoʻolālā he nui o nā mea hoʻololi uila mana, kahi i hoʻolako ʻia ai kahi waihona aila waho.
ʻO 135….145 ka pae kiko uila maʻamau no nā ʻaila transformer°H.
Lahi paila o ka aila transformer
Pili ia i ka haku mele ʻana o nā hakina. ʻO ka helu hoʻolapalapa o ka ʻaila paraffin, i hana ʻia mai nā ʻāpana ʻoi aku ka paʻa a hiki i nā wela kiʻekiʻe, ma kahi o 530°C. ʻO ka aila Naphthenic e paila ma 425°C.
No laila, i ke koho ʻana i ka hoʻohui ʻana o ka media cooling, pono e noʻonoʻo kekahi i nā kūlana hana o ka transformer a me kāna mau hiʻohiʻona hana, ʻo ka mea mua, ka pōʻai hana a me ka mana.
