10kV S13(20,22)-M series energy-efficient oilimmersed distributio
1. Product Introduction:
10kV grade S11(20, 22)-M series energy-saving oil-immersed distribution transformers use high-quality, high magnetic permeability cold-rolled grain-oriented silicon steel sheets for the core, stacked with 45° full oblique joints. This series features superior performance, low operating noise, and compact structure. It is a new generation of environmentally friendly, high-efficiency energy-saving products suitable for urban and rural power grid renovations in industrial and mining enterprises, and is especially suitable for compact pre-installed box-type substations.
2. Standards:
2.1 IEC60076-1 Power Transformers
2.2 GB/T1094.1 Power Transformers
2.3 GB/T6451 Technical Parameters and Requirements for Oil-immersed Power Transformers
2.4 JB/T10088 Sound Level of 6kV to 500kV Power Transformers
2.5 GB20052-2020 Energy Efficiency Limits and Energy Efficiency Grades for Power Transformers
3. Model and Meaning:
4. Structural Features:
Core: Entirely made of high-quality, high magnetic permeability grain-oriented cold-rolled silicon steel sheets with full oblique, hole-free binding structure. The core is multi-stage stepped with three, five, or seven joints, resulting in low no-load loss and low noise.
Windings: Made of high-quality QQ acetal enameled round copper wire, flat copper wire drawn from oxygen-free copper rods, or copper foil. The forms include cylindrical, continuous, new spiral, and split types, providing sufficient electrical strength, mechanical strength, heat dissipation capability, and resistance to sudden short circuits.
Oil Tank: Made of high-quality steel plates welded together, available in oval or rectangular shapes. Heat dissipation elements use plate-type radiators or corrugated oil tanks. The oil tank undergoes reliable sealing tests in the factory. Both internal and external surfaces are treated with acid washing and phosphating, followed by three coats on the bottom and one on the sides of paint spraying, making it both corrosion-resistant and aesthetically pleasing.
