Transformer mafuta GK

Technical specifications

Kuumbwa uye maitiro emafuta e-transformer giredhi GK anotarirwa nemitemo yeGOST 982-80. Mitemo iyi inoreva:

• Yakakwirira magetsi ekudzivirira kushanda, kusanganisira pane yakakwirira tembiricha.
• Kuvapo kwe antioxidant additives (ionol), kusasanganisa ngura pasi pemhepo yakakwira.
• Kusavapo kwemvura-soluble alkalis uye mechanical tsvina.
• Kugadzikana kwezviratidzo zve viscosity mune imwe nzvimbo yekushisa.
• Minimum content yemahara acid ions.

Iwo akajairwa physico-kemikari maitiro echigadzirwa chakatsanangurwa ndeaya:

1. Density, kg / m³, pakamuri tembiricha - 890±5.
2. Kinematic viscosity, mm²/ s, patembiricha ye50 ^°C, kwete zvishoma - 9 ... 10.
3. Kinematic viscosity, mm²/s panguva shoma yakakurudzirwa tembiricha yekunyorera -30 ^°C, isingasviki 1200.
4. Relative acid yakasara maererano neKOH, kwete kupfuura 0,01.
5. flash point, ^ºC, kwete pasi pe135.
6. Kupisa tembiricha, ° С, kwete pasi pe -40.
7. Iyo inomisa oxidation coefficient mushure mekupera kwenguva yewaranti yekushandiswa kwechigadzirwa, kwete kupfuura 0,015.

Kuparara kwemagetsi kweGK giredhi mafuta ndeye 2 kV, iyo inonyatsoenderana nezvinodiwa zvehunyanzvi zveGOST 6581-75.

Ndeupi musiyano uripo pakati peGK neVG transformer oiri?

Mineral oiri VG inoitirwa kushandiswa mukuisa magetsi - capacitor mabhangi, ballasts uye relays, izvo zvakagadzirirwa kushanda voltages kusvika 1,15 kV. Izvi zvinokonzerwa nekuvapo kwe inhibitory additives mukugadzirwa kwemafuta, izvo zvinoderedza kusimba kwemaitiro ekuora, asi panguva imwechete kuderedza dielectric properties.

Transformer mafuta GK inoonekwa semi-synthetic, sezvo ine yakawedzera muzana yeanti-corrosion, dielectric uye inhibitory additives. Izvi zvakaitwa kuitira kushandisa mamwe anosvikika mafuta anovava kubva kuWest Siberian deposits mukugadzirwa kwechigadzirwa chekupedzisira. Nekudaro, zvinokwanisika kuchengetedza yakatsiga tembiricha kukosha muakavharwa mavhoriyamu emagetsi emagetsi. Nekudaro, panguva imwecheteyo, kushorwa kwesimbi kwezvikamu zvemidziyo mubhati ine HA mafuta kunoderera.

Mazano ehunyanzvi anokurudzira kushandisa GK mafuta kusvika kutsiva kwenguva isingasviki gore. Kudzora kwemhando yechigadzirwa kunoitwa zvinoenderana neanoona maitiro - pachena, kuvapo kwemechani sediment - uye kuvapo kweakawanda acid ions. Pamafuta eGK, iyi chiyero ndeye 0,015 (pamusoro pechiratidzo ichi, iyo inobvumirwa kuputsika kwemagetsi inodonha kusvika ku750 V). Mumafuta eVG, nekuda kwekushaikwa kwemaion emahara, hapana kana kuparara kwekuita nekufamba kwenguva.

Maitiro ekushandisa uye wongororo

Unhu hweGK transformer mafuta hunoenderana nemugadziri wayo. Iyo shoma muzana yemakomponi esarufa yakajairwa kune zvigadzirwa zvinogadzirwa kuUfaneftekhim JSC, Nefteorgsintez Kstovsky bhizinesi uye Omsk refinery. Vamwe vanogadzira vanowedzera huwandu hwekuwedzera kwegasi-resistant additives kune yekupedzisira chigadzirwa, iyo inowedzera inobvumirwa tembiricha, asi inoderedza dielectric performance. Mafuta ekushandura akadaro pamwe chete anoenderana nezvinodiwa zveGOST 982-80, asi hazvikurudzirwi kune simba guru remagetsi.

Mutengo paitare

Nekutenga kwakawanda, mutengo webhari imwe yemafuta (200 malita) inodhura kubva ku14000 kusvika ku16000 rubles. Mutengo wekutengesa wemafuta eGK per litre (kana yakazara mu 20 l canisters) inobva ku140 ... 150 rubles.
