摘　　要：电力系统中不可避免的短路事故层出不穷,为提高变压器抗短路能力设计,根据变压器短路试验的基本情况、数学模型和受力情况,分析了变压器短路试验过程中出现的各种故障前兆及其原理。最后,根据试验结果情况提出了关于提高变压器抗短路能力的措施和建议,对变压器抗短路能力设计有一定的指导意义。Short-circuit accidents in the power system often occur inevitably, to improve the design of the transformer withstand short-circuit capability, the basic principles, mathematical model and stress in transformer short-circuit test were described. Various fault precursors and its principle appearing in the process of transformer short-circuit test were also analyzed. At last, According to the results of experiment, the proposal to raise ability to withstand short-circuit of power transformer were offered, which has instructive significance to improve ability of withstand short-circuit design.
