摘　　要：近几年,110kV及以上电压等级变压器的短路损坏事故频发。文中针对1990～1998年间全国电力系统的变压器运行和事故数据,分析短路事故现状,总结事故特点和规律,为运行部门提高设备安全运行管理水平、变压器制造厂提高设备抗短路能力,提供了客观依据。110kV and higher transformers have been damaged frequently due to short circuit in recent years. This paper analyzes the present status, features and rules of short circuit faults based on transformer operation and fault data of China during years from 1990 to 1998. These provide objective basis for promoting management level for operational departments and improving short circuit withstanding ability for manufacturers
