抗干扰适配器的最优化设计

The Optimum Design of Anti-Interference Adapter

电气化铁路钢轨中不平衡牵引电流有时可高达１００Ａ。这对移频信号设备的安全工作带来了威胁，严重时可能烧毁设备，危及行车安全。为了抑制这种干扰，需要设计一种抗干扰适配器，现采用多目标有约束的混合非线性优化方法进行设计。理论分析和实际测试都较好地满足了设计的要求。

Under the condition of great current traction,the unbalanced current on rail may as high as 100A,which interferes with the equipment of Shift-Frequency Signal(SFS),sometimes even damages the equipment and interrupts the normal routine of traffic.In ordr to solve this problem,an adapter which can not only provide a channel for SFS,but also isolate the interference of the unbalanced current at 50Hz is designed,and a non-traditional method nonlinear multiobjective hybrid optimum method,is derived.The theoretical anallysis and actual measurement results are satisfactory.
