The S-M type distribution transformer is suitable for three-phase 50HZ, 10KV voltage level distribution systems, used for industrial and agricultural power distribution, power and lighting.
Execution standard: GB/T1094.1、GB/T1094.2、GB/T1094.3、GB/T1094.5、GB/T1094.10、GB/T6451、GB20052 The transformer products produced by our company meet the new version of the above standards.
Usage environment:
1. The altitude of the installation site shall not exceed 1000m, the ambient temperature shall not be higher than 40 ℃, not lower than -25 ℃, the highest daily average temperature shall be 30 ℃, and the highest annual average temperature shall be 20 ℃.
2. Operating environment, relative humidity not exceeding 90% (ambient temperature 25 ℃)
3. When installing the product, it should generally be 800mm away from walls and other obstacles, and there should be a distance of 300mm between adjacent transformers. The above distance can be adjusted appropriately for distribution boxes and other situations where installation space is limited.
4. In general, transformers can be placed directly at the usage site and can be put into operation after installation and inspection. For situations with seismic and other special requirements, the foundation for installing transformers should be embedded with bolts and fixed with bolts and nuts.
Adopting a fully sealed corrugated sheet fuel tank structure, rated capacity (kVA): 30-2500; High voltage: 6, 6.3, 10kV ± 2 × 2.5%; Low voltage: 0.4kV; connection group Yyn0, Dyn11; Impedance voltage 4%, 4.5%, 5.0%; Transformers of 800KVA and above are equipped with signal thermometers and gas relays, and are equipped with pressure relief valves. Divided into three levels of energy efficiency (S13 – M), two levels of energy efficiency (S20 – M), and one level of energy efficiency (S22 – M).
Three‑phase Oil‑immersed Stacked‑core Transformer
The S-M series 10kV oil immersed transformers designed and produced by our company adopt a fully sealed corrugated sheet oil tank structure, which has strong overload capacity, strong resistance to short circuit and overvoltage, energy-saving and environmentally friendly, reliable long-term service life, low noise, low loss, small size, and beautiful appearance.
The S-M type distribution transformer is suitable for three-phase 50HZ, 10KV voltage level distribution systems, used for industrial and agricultural power distribution, power and lighting, especially for reducing noise, improving environmental quality and reducing power operating costs in cities. Compared with the S9 and S11 models currently used in urban network construction, the average no-load losses have decreased by 50% and 30% respectively, and the noise level has decreased by 5-8 dB.
