海东变压器厂：阻抗电压计算

海东变压器厂：阻抗电压计算
    阻抗电压的计算是海东变压器计算中很重要的工作，阻抗电压值是海东变压器重要性能数据，标准系列的海东变压器阻抗电压在性能标准中已有规定。
    在额定电流下分接阻抗电压的允许偏差，一般为±10%，但由于制造上的偏差和试验误差的存在，所以一般要求阻抗电压的计算值和标准值的偏差不大于±2.5%。
阻抗电压包括电阻电压降和电抗电压降两个分量，一般电阻电压降很小，对于8000kVA及以上的海东变压器可略去不计。
 
Impedance voltage calculation
 
    The calculation of the impedance voltage transformer calculation the impedance voltage values ??are important performance data of the transformer, the transformer primary impedance voltage of the standard series is already provided for in the performance standards.
    To main tap impedance voltage at rated current allowable deviation is generally ± 10%, but because of the existence of variation in manufacturing and the experimental error, so the general requirements for the impedance voltage of the calculated values ??and the standard deviation is not greater than ± 2.5% .
Including resistor voltage drop and electrical impedance voltage against voltage drop two components, general resistance voltage drop is small, 8000kVA and above transformer is negligible.
