S□-M.ZT series on-load capacity regulating transformer

The oil tank of 10kV on-load capacity regulating transformer adopts fully sealed corrugated structure, and the expansion coefficient of corrugated sheet fully meets the requirements of transformer oil expansion and heat dissipation. The body adopts a new type of insulation structure, the transformer has strong short-circuit resistance, adopts domestic high-quality high-permeability oriented silicon steel sheet, 45-degree full oblique step joint, high and low voltage windings are all copper windings, cylindrical structure, and all fasteners adopt anti-loosening treatment. The intelligent on-load capacity regulating and voltage regulating switch can automatically realize star (Y)-angle (D) connection switching of high-voltage winding and series-parallel switching of low-voltage winding to realize on-load capacity regulating and voltage regulating.

Performance characteristics

1. On-load capacity regulating and voltage regulating transformer has two capacity gears, which can automatically adjust capacity and on-load voltage regulating.

2. When the load is light or close to no-load, in the case of no power failure of the transformer, it is automatically adjusted from large capacity to small capacity operation, which not only greatly reduces the no-load loss, but also overcomes the trouble of manual operation of power failure, and truly achieves the purpose of energy saving and intelligence.

3. According to the real-time situation, the output voltage and capacity of the transformer can be switched adaptively, which ensures the voltage quality of the low-voltage side, improves the system power factor and reduces the reactive power consumption. Equipped with low-voltage power distribution management terminal, it can realize automatic capacity adjustment, automatic voltage regulation, power distribution detection, reactive power compensation, power acquisition and wireless "four remote" functions.

4. It has a wide range of applications in cities, has significant energy-saving effects, can save a lot of power consumption and operating costs, has significant social benefits, and the operation of the power grid is safer and smarter.
