摘要
为对变流干式变压器的新产品进行检测,判断其温升试验的要求,按标准IEC61378-1IEC:2011(E)和IEC 61378-2IEC:2001(E)提供的相关检验依据,具体讨论星角联结的干式整流变压器等效电流的计算方法。简要叙述了矿用变流干式变压器总运行负载损耗的组成、谐波对负载损耗的影响,介绍了矿用变流干式变压器温升试验等效电流的计算方法和实例。
In order to solve the test and judge the requirements of temperature rise test for new products of converter dry type transformer, according to the relevant test standards provided by IEC61378-1 C IEC :2011 (E) and IEC 61378-2 IEC :2001 (E). Discusses the calculation methods for dry type rectifier transformer equivalent current of star comer link, and describes the composition and the effect of harmonics current of total service loading loss of mine converter dry type transformer. Introduces the calculation method and example of equivalent current on temperature rise test for mine converter dry type transformer.
