摘　　要：由于社会的不断进步,我国的电力企业也在迅速的发展,随着电力装机容量的不断增长,抗短路能力不足的问题已经成为电力变压器事故的首要原因,对电网造成很大危害,严重影响了电网安全运行。针对这种情况,分析变电器绕组导线对抗短路能力的影响作用,确保电网的安全、可靠运行。阐述了绕组导线规格对变压器短路时辐向力的影响,并提出了措施。Based on rapidly developing electric power enterprises in China and continuous growth of power installed capacity, the anti short circuit ability had become a key reason for power transformer accident, which caused damage for electrified wire netting and affected its safe operation. Thus, it was necessary to find reasons and analyze effect of transformer winding wire against short circuit capability to ensure safe and reliable operation of power grid. In this paper, effect of force speeifieations winding wire to transformer short circuit was discussed and a few measures were put forward.
