| Abstract: | The load types,the overload limit-value during operation and the calculation of hot spot temperature of winding of large transformer were introduced.According to the thermal characteristic of the transformer,the normal cyclic overload capacity and the accidental overload capacity were calculated respectively.The calculation method of transformer's overload capacity was put forward,as well as the operation requirement for overload during accidents. |
