PRODUCT INTRODUCTIONPRODUCT ADVANTAGES Rectifier
transformer is the power transformer of rectifying device. The
rectifying device is characterized by the input AC from the primary
side and the output DC from the secondary side through the
rectifying element. A transformer used as the power supply of
rectifying unit is called a rectifier transformer. Most of the
industrial rectifying DC power supply is obtained from AC power
grid through the rectifier transformer and rectifying device.Main
functions: Supply appropriate voltage to the rectifying system;
Reduce the pollution of the power grid caused by the waveform
distortion caused by the rectifier system.Operating
conditions 1. The altitude does not exceed 1000
m 2. The max. ambient temperature is + 40 ºC
Maximum daily mean temperature: + 30 ºC
Maximum annual average temperature :+ 20
ºC Minimum temperature -30
ºC (suitable for outdoor transformer)
Minimum temperature-5 ºC (suitable for indoor
transformer) 3. The waveform of the power supply
voltage is approximate to a sine wave 4. Power
supply voltages connected by poly-phase transformers shall be
approximately symmetrical PERFORMANCE CHARACTERISTICS1.
Stable electrical performance: Combined with load characteristics,
voltage fluctuation of power grid and over-voltage of air,
according to the load condition of rectifier transformer, the
product determines reasonable and reliable insulation level and
insulation model to ensure the reliable and stable electrical
performance.2. High dynamic stability: Product windings are with
high mechanical strength and strong burst resistance to meet the
extremely harsh load environment. In the designing and
manufacturing process, the dynamic unstable source caused by the
leakage of the transformer or the abnormal transportation can be
eliminated. The product has high dynamic stability. High
impedance,30% higher than the power transformer of the same
capacity which effectively protect the rectifier components;3. Good
thermal stability: Strictly control the heating position and the
hottest temperature rise of the product and leave sufficient
temperature rise margin. Axial air duct can be added in the coil
when necessary, select cooling method and reasonable distribution
of gas flow according to the coil load loss value to achieve the
best cooling effect and the main temperature rise index is at least
5 ºC lower than the national standard. The coil and lead is
copper wire, and the current density is low;4. Strong overload
capacity: The product is with strong overload capacity and
over-voltage capacity which can be long-term safe operation under
rated load and under 110% over-voltage (ambient temperature
40 ºC);The terminal connected with the motor can withstand 1.5
times of the rated current and lasting 5S. Product design and
manufacturing fully consider the load characteristics, select from
temperature rise, insulation and accessories to meet the overload
requirements;5. Superior performance index: Free load current
design and manufacturing value is lower than the national standard
value transformer of the same capacity when fully considers the
economy and reliability of users;6. The energy-saving effect is
obvious and the noise is low;7. Simplified structure and nice
appearance.TECHNICAL PARAMETER 1. Rated capacity:
250-2500kVA2. Rated voltage: Primary voltage: 10kV,
6kV; Secondary voltage: 0.69 * 15/ 0.38, 0.72 * 24/ 0.38 and
