The invention discloses a medium-voltage direct-current distribution board magnetic field control method and a medium-voltage direct-current distribution board. According to the medium-voltage direct-current distribution board, external magnetic field characteristics generated by a main busbar and a whole distribution board cabinet in a power-on state are determined through simulation: firstly, magnetic field characteristics of the main busbar under initial design are determined; then determining magnetic field characteristics after magnetic field shielding measures are taken; then optimizing the main busbars, firstly determining the number and the arrangement mode of the main busbars, then determining the size and the arrangement spacing of the busbars, and then determining the magnetic field characteristics of the optimized main busbars; finally, a main busbar optimization scheme capable of greatly reducing the external magnetic field of the medium-voltage direct-current distribution board is determined through comparison of simulation results. According to the invention, the magnetic field generated by the busbar can be greatly inhibited when normal working current passes through the busbar, so that the influence on the magnetic characteristics of the ship is reduced, and the safe navigation of the ship is ensured.
本发明公开一种中压直流配电板磁场控制方法、中压直流配电板,通过仿真确定通电状态下主汇流排及配电板整柜产生的外部磁场特征:先确定主汇流排在初始设计下的磁场特征;然后确定采取磁场屏蔽措施后的磁场特征;然后对主汇流排进行优化,先确定主汇流排的根数及排布方式,再确定汇流排的尺寸和排布间距,再确定主汇流排优化后的磁场特征;最后通过仿真结果对比确定能大幅降低中压直流配电板外部磁场的主汇流排优化方案。本发明能够在汇流排通过正常工作电流时大幅度抑制其产生的磁场,从而降低对舰船磁特性的影响,保证舰船的安全航行。
