oil immersed distribution transformer,
oil immersed power transformer
The product is fully oil filled seal type. The principle is the same as that of sealed power transformer. The basic elements of amorphous alloy are iron, nickel, cobalt, silicon, boron and carbon. It is a kind of isotropic soft magnetic material, with small magnetizing power and no structural defects hindering the domain wall movement. The thickness is very thin, only 0.027mm, the filling coefficient is correspondingly smaller, only 0.75-0.8, the electrical resistance is very high, 3-6 times of silicon steel plate, the hardness is 5 times of silicon steel plate, and the amorphous gold material is particularly sensitive to the stress.
|voltage level (kV)||Vector Group||
The transformer core is made of amorphous alloy cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is bound to ensure the compactness of the core and reduce noise.
The coil is rectangular, the high voltage is made of acetal enamelled wire, and the low voltage is made of oxygen free copper wire or copper foil coil, so as to increase the ability of the transformer to withstand short circuit.
3. Oil tank
The oil conservator is cancelled, and the chip radiator replaces the oil tube as the cooling element. The air cushion is filled on the oil tank, which can expand with the volume of transformer oil expansion and compression, isolation of transformer oil from atmosphere, prevention and mitigation of oil quality deterioration and insulation damp, enhancement of operation reliability, daily operation maintenance-free.
1. The maximum ambient air temperature shall not exceed 40 ℃, and the minimum shall not below - 25 ℃;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;
3. The vertical inclination is no more than 5 °, and no violent vibration and impact;
4. The air humidity is not more than 90% (+ 25 ℃);
5. No gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m / s.
7. If service conditions beyond the above, specially customized product is available.
1 clients need advise main parameters of the transformer like capacity, input voltage, output voltage and connection group in inquiry.
2 other custom requirement.
