摘　　要：当单片机与接触器装在同一箱体时 ,接触器线圈在通、断电时产生的电磁干扰 ,控制接触器线圈通电、断电的按钮开关在通、断电时产生的火花干扰 ,均使单片机应用系统不能正常工作。本文介绍了分相、TVP、阻容吸收、延时。On the occasions of monolithic microcomputer and contactors are packed in one case, electromagnetic interferences, yielded by contactor coils as they are switched on or off, and spark interferences, generated by the pushbutton switches that control contactor coils as they are switched on or off, all make monolithic microcomputer application system work improperly. The article introduces inhibiting methods such as phase splitting, TVP, resistive and capacitive absorbing, time delay and coupling removing.
