Mafuta a Transformer GK

Zolemba zamakono

The zikuchokera ndi katundu thiransifoma mafuta kalasi GK zimatsimikiziridwa ndi miyezo ya GOST 982-80. Malamulo awa akutanthauza:

• Kuchita kwamphamvu kwamagetsi kwamagetsi, kuphatikiza pa kutentha kokwera.
• Kukhalapo kwa antioxidant zowonjezera (ionol), kupatula dzimbiri pansi pa voteji.
• Kusowa kwa alkalis osungunuka m'madzi ndi zonyansa zamakina.
• Kukhazikika kwa zizindikiro za viscosity mumtundu wina wa kutentha.
• Zochepa zomwe zili ndi ayoni a asidi aulere.

Miyezo yodziwika bwino ya physico-chemical yazinthu zomwe zafotokozedwa ndi:

1. Kachulukidwe, kg / m³, kutentha kwa chipinda - 890±5.
2. Kinematic mamasukidwe akayendedwe, mm²/ s, pa kutentha kwa 50 ^°C, osachepera - 9 ... 10.
3. Kinematic mamasukidwe akayendedwe, mm²/ s pa osachepera analimbikitsa ntchito kutentha -30 ^°C, osapitirira 1200.
4. Asidi achibale otsalira malinga ndi KOH, osapitirira 0,01.
5. pophulikira, ^ºC, osachepera 135.
6. Kutentha kwakukulu, ° С, osachepera -40.
7. Kuchepetsa makutidwe ndi okosijeni coefficient pambuyo kutha kwa nthawi chitsimikizo kwa ntchito mankhwala, osapitirira 0,015.

Magetsi owonongeka a mafuta a kalasi ya GK ndi 2 kV, omwe amagwirizana ndi luso la GOST 6581-75.

Kodi pali kusiyana kotani pakati pa mafuta osinthira a GK ndi VG?

Mafuta a Mineral VG amapangidwa kuti azigwiritsidwa ntchito poyika magetsi - mabanki a capacitor, ma ballasts ndi ma relay, omwe amapangidwa kuti azigwira ntchito mpaka 1,15 kV. Izi ndi chifukwa cha kukhalapo kwa zoletsa zina mu kapangidwe ka mafuta, amene amachepetsa mphamvu ya dzimbiri njira, koma nthawi yomweyo kuchepetsa dielectric katundu.

Mafuta a Transformer GK amatengedwa ngati semi-synthetic, popeza ali ndi kuchuluka kwa anti-corrosion, dielectric and inhibitory additives. Izi zidachitidwa kuti agwiritse ntchito mafuta owawasa opezeka ku West Siberian deposits popanga chomaliza. Chifukwa chake, ndizotheka kusunga kutentha kosasunthika m'mavoliyumu otsekedwa a ma transformer amphamvu. Komabe, pankhaniyi, kukana kwa dzimbiri kwa zida zachitsulo zomwe zili mu bafa ndi mafuta a GK zimachepa.

Malingaliro aukadaulo akuwonetsa kugwiritsa ntchito mafuta a GK mpaka kusinthidwa kwa nthawi yosapitilira chaka chimodzi. Kuwongolera kwamtundu wazinthu kumachitika molingana ndi mawonekedwe - kuwonekera, kukhalapo kwa dothi lamakina - ndi kukhalapo kwa ayoni owonjezera a asidi. Kwa mafuta a GK, mlingo uwu ndi 0,015 (pamwamba pa chizindikiro ichi, mphamvu yowonongeka yovomerezeka imatsikira ku 750 V). Mu mafuta a VG, chifukwa chosowa ma ion aulere, palibe kuwonongeka kwa magwiridwe antchito pakapita nthawi.

Ntchito ndi ndemanga

Ubwino wa mafuta a GK transformer umadalira wopanga wake. Chigawo chochepa cha mankhwala a sulfure ndi omwe amapangidwa ku JSC Ufaneftekhim, Kstovo enterprise Nefteorgsintez ndi Omsk refinery. Opanga ena amawonjezera zowonjezera zowonjezera zosagwirizana ndi gasi kuzinthu zomaliza, zomwe zimawonjezera kutentha kovomerezeka, koma zimachepetsa ntchito ya dielectric. Mafuta a thiransifoma amtundu uliwonse amagwirizananso ndi zofunikira za GOST 982-80, koma osavomerezeka kuti akhale ndi mphamvu zapamwamba zamagetsi.

Mtengo pa lita

Ndi kugula chochuluka mtengo wa mbiya imodzi ya mafuta (malita 200) ndalama kuchokera 14000 kuti 16000 rubles. Mtengo wogulitsa wa mafuta a GK pa lita imodzi (pamene utadzaza mu 20 l canisters) umachokera ku 140 ... 150 rubles.
