摘　　要：针对船用大容量变压器空载合闸造成的冲击电流进行分析,并提出采用预充磁手段进行冲击抑制.利用Matlab/Simulink仿真平台搭建变压器在不进行预充磁和进行预充磁状态下的仿真模型进行分析验证.The surge current of ship using transformer was analyzed when switching on with no load. A method of pre-excitation was given to restrain the surge current. A simulation flat roof is built by Matalb/Simulink PSB block and the ship is tested by transformer under pre-excitation and without pre-excitation.

关 键 词：变压器 空载合闸 预充磁
