摘　　要：某60000kVA特种电炉变压器高压侧B相绕组发生短路崩毁故障,对此变压器其三相高压侧绕组必须重新绕制,拆装壳式铁芯来完成大修工作,并对其缺陷进行改造,使该变压器修复后的技术参数、性能等均优于改造前。The B-phase winding of the high voltage side of the 60000 kVA special electric furnace transformer had a short-circuit collapse fault.For this reason,the threephase high voltage side winding of the transformer must be rewound,the shell type iron core must be disassembled to complete the overhaul work,and its defects must be re?formed.The technical parameters and performance of the repaired transformer were im?proved after the transformation.
