摘要
煤矿中变压器额定电流的估算对于了解变压器工作性能,对变压器进行调试维护有着重要影响。介绍三相变压器额定电流的一次、二次经验估算法,单相变压器额定电流估算法,并介绍其他常用估算方法。将估算结果与实际电流相比较,估算误差控制在4%以内,估算较为准确,有着良好的实用价值。
The current estimates is important for understanding the performance of the transformer and has an important impact for the transformer maintenance. Describes a three-phase transformer rated current, secondary empirical estimation method, single-phase transformer rated current estimation method, and other commonly used estimation methods. Comparing the results with the actual current, the error is less than 4%. The estimate is accurate and has practical value.
