Oil type Rectifier transformer

I produced the rectifier transformer rectifier unit is used as power transformers, whose role is to provide AC power to the rectifier, rectifiers convert alternating current to direct current and then, so that the DC power supply. Mainly used in metallurgy, chemical industry, locomotive traction and other transmission industries. Technically learned Alstom's successful experience, the choice of high-performance silicon and oxygen-free high-quality materials, the use of advanced production phase coil package technology, lead cold pressure welding technology, fuel tank seal surface precision processing technology, so that products with energy-saving, low loss, low noise, shock and short-circuit capability, strong overload capacity, compact structure, small size, power and reliable, and can meet user specific requirements.
(1) stable electrical performance: product combines load characteristics and voltage fluctuations, atmospheric over-voltage conditions, according to the load rectifier transformer, determine a reasonable and reliable insulation levels and dielectric model, confiscation ensure reliable and stable electrical performance. Product Environmental safety factor ≥1.67.
(2) high degree of dynamic stability: The product has high mechanical strength winding, with a strong anti-burst capacity to meet the extremely harsh environment of the load. In the design, the manufacturing process could eliminate the sources of instability or abnormal motion transformer magnetic flux leakage caused by transportation may cause. Products with high dynamic stability. High resistance, 30% higher than the impedance of the power transformer with the capacity to suppress di / dt, effective protection rectifier elements.
(3) Thermal stability: advanced product design, strict control products and the hottest parts of the heating temperature, and allow sufficient temperature margin, as necessary, a coil Jiatian axial oil passage, according to the coil Cooling load loss value selection and reasonable allocation of the oil flow, to achieve the best cooling effect, mainly low-temperature indicators than the national standard of at least 5 ℃. Coil, copper wire lead, select a lower current density.
(4) strong overload: The product has a strong overload capacity and over-voltage, long-term safe operation at rated load, can be at 110% of full load over-voltage long-term safe operation (ambient temperature 40 ℃); can withstand the transformer terminals associated with the motor 1.5 times the rated current, which lasted 5S. Product design, manufacture fully consider load characteristics, to meet the temperature, insulation and accessory selection and other aspects of overload requirements.
(5) performance advantage: no-load current design, manufacture value is lower than the national standard S9 series transformer of the same capacity is based, economy and reliability fully user.
(6) the effect of significant energy-saving, low noise (<65dB).
