低电压短路试验校核110kV国际变压器容量

Checking Capacity of 110 kV Transformer with Low Voltage Short Testing

变压器的容量与其对应的阻抗电压在国标中有相关的规定和强制标准,厂家在变压器出厂时测得的阻抗电压值应在国标允许的范围内。文中通过对变压器低电压短路试验的研究,总结出测量变压器短路阻抗百分数核对110kV变压器容量的方法,该方法适用于国标变压器的核容试验。通过某用户2台110 kV国标变压器的核容试验,表明该方法具有可行性。

Based on the analysis of the low voltage short testing,the percentage of short-circuit impedance was proposed to checking capacity of 110 kV transformer.And the method is suitable for checking the national specification transformer.Lastly,the proposed method is verified feasible through the capacity checking test of two 110 kV transformer.
