Transformer mafuta VG

Mapangidwe ndi katundu

Kuphatikizika kwa zigawo, zomwe zimatsimikiziridwa ndi zofunikira zogwirira ntchito (zoperekedwa mu GOST 982-80), zikuphatikizapo:

• Mafuta amchere amchere, omwe amayamba ndi sulfuric acid, kenako amayeretsedwa.
• Antioxidant zowonjezera.
• Corrosion inhibitor.

Mawonekedwe akuluakulu amafuta ndi mankhwala:

1. Kachulukidwe kutentha firiji, kg/m³ 840 ± 5.
2. Kinematic mamasukidwe akayendedwe, mm²/ s, pa kutentha kwapansi kwa 50 ^°C - 6 ... 7.
3. Kutentha kwa ntchito, ^°Ndi - kuchokera -30 mpaka +60.
4. Kukhuthala kwa malire pamalo othira, mm²/c -340.
5. Nambala ya asidi malinga ndi KOH, osati apamwamba - 0,02.
6. pophulikira, ^°C, osachepera 140.

Zizindikirozi zimagwirizana kwathunthu ndi malingaliro apadziko lonse, omwe amatchulidwa muyeso ya ASTM D 4052. Kufotokozera chidule cha mtundu: C - mankhwala apamwamba kwambiri, G - teknoloji yowonongeka ya hydraulic imagwiritsidwa ntchito popanga mafuta (mitundu ina yamafuta amakono a thiransifoma, mwachitsanzo. , mafuta a GK amapezeka mofananamo) .

Kugwiritsa ntchito

Chifukwa chotsika kwambiri cha zotsalira za asidi, VG thiransifoma yochokera ku Lukoil imatha kugwiritsidwa ntchito mosamala m'malo ovuta kwambiri ogwiritsira ntchito ma transfoma ndi zida zina zamagetsi kuti azigwira ntchito mosalekeza. Zomwe zimapangidwa ndi zigawozi zimakhala ndi dielectric nthawi zonse mpaka mphamvu zamagetsi za 1,35 kV, zomwe zimapangidwira zipangizo zosiyanasiyana zoyambira zamainjini amphamvu, mapampu, majenereta ndi mpweya wabwino. Chogulitsacho chimapereka dongosolo lokhazikika la kutentha kwa zipangizo monga ma capacitor akuluakulu, makina opangira mafakitale, otembenuza panopa.

Zinthu Zapadera:

• Kupewa kuwunikira kwamagetsi ndi kutulutsa kwa arc, komwe kumachitika nthawi zambiri pakakhala kuwonjezeka kosalamulirika kwa kutentha kwamkati mkati.
• Matenthedwe bata la zikuchokera.
• Kukhazikika kwazinthu za dielectric zomwe zimagwirizanitsidwa ndi kusowa kwa ma ion aulere.
• Mkulu kuzirala mphamvu.

Ukadaulo wamakono wopangira giredi yamafuta a VG kuchokera ku Lukoil sikuphatikiza zonyansa zilizonse zamakina ndi matope panthawi yogwira ntchito. Chifukwa chake, kulimba kwa ntchito yokonza makhazikitsidwe amagetsi pogwiritsa ntchito mankhwalawa kumachepetsedwa kwambiri.

Mtengo pa lita

Mtengo wamafuta a thiransifoma VG zimatengera kuchuluka kwa kugula. Ogulitsa ogulitsa amapempha kulongedza mu migolo ya 180 kg - kuchokera ku 13000 ... .14000 rubles. Zopereka zogulitsa mankhwalawa pamasitolo (mu zitini za malita 20) ndizosowa kwambiri. Kawirikawiri mtengo wa lita imodzi muzochitika zotere ndi 60 ... 80 rubles.

Tikayang'ana ndemanga za ogwiritsa ntchito, mafuta osinthika ofotokozedwa amakwaniritsa zomwe ogula amayembekezera. Makamaka pa kutentha kwakunja kozungulira. Mukamayitanitsa, muyenera kulabadira zambiri pazomwe wopanga amapanga. Matchulidwe olondola ndi TU 38.401-58-177-96, nthawi zina, zinthu zabodza zopanda pake zimatha.
