铁道专用二相变三相逆斯科特变压器

   平衡牵引变压器的输出α、β相角差为90°的二相制电源，所以站用电变压器（一般为50-100kVA的27500V/400-231V的供站内自用的配电变压器）应采用本公司配套的二相变三相逆斯科特变压器，将27500V的二相制电压再逆变为400-231V的三相四线制电源，以解决站用电的问题。

特点：
1．采用了一系列的措施以满足其较高的动、热稳定性的要求，绕组温升低。
2．损耗低。
3．绝缘强度高。
4. 能安全、可靠地运行于海拔2500m以下的污秽环境中。

2-phase/3-phase Re-scott Transformer for Railway Use:

   
  The output αphase,βphase of balance traction transformer form two-phase system of power supply. The angular phase difference is 90 . Therefore, our supported 2-phase/3-phase Re-scott Transformer should be adopted for substation transformer (commonly, 50~100kVA 27500V/400~231V distribation transformer for self-use in subseation). We invert the 27500V two-phase system voltage to 400-231V three-phase four wires system of power supply to solve the problem of power-supply in subsation.

Characteristics:
1. Series of measures are taken to meet requirement of higher dynamic and thermal stability.Temperature rise of winding is low.
2. Low loss.
3. High insulation intensity.
4. It can safely and reliably operate in dirty circumstance under 2500m of altitude above sea level.
