摘　　要：当变压器处于负载运行时,随着输出电流的增加,其外特性显现出一定的变化特点,并且该特点还受其所带负载性质的影响.为了清楚解释这一现象,本文利用电工学中的相量知识深入分析变压器外特性变化特点及其受负载性质影响的原因.分析结果表明,相量分析法能够清楚解释变压器外特性变化的原因及其与负载性质的关系,可以帮助读者更好地理解变压器工作特性及运行特点.While transformer running for load,certain changing characteristics on its external characteristic appear with increase of output current,and the characteristic is also affected by the load property.To clearly explain the phenomena,the external changing characteristic and the influenced cause from the load property were deeply analyzed with electrotechnics phasor knowledge in the paper.Analysis results indicate that the reason of transformer changes in external characteristic and its relationship with the property of the load can be clearly explained with the method of phasor analysis so as to help readers better understand the transformer operating characteristics and operation characteristics.
