摘要
电子束焊机加速电源中由于高压变压器杂散电容的耦合作用，在束流采样电阻上产生较大的干扰信号，从而给焊机运行带来不利影响。文章通过分析干扰信号产生的机理，提出采取双屏蔽措施，经实际应用表明是行之有效的。
Coupling of mixed capacitor in high-voltage transformer may produce disturbance signal in beam current sampling resistance, and it will effect the welding machine. This paper analyses the mechanism of disturbance signal producing, and points that it is effective to adopt double screen technology.
