3） 变频器控制原理图；

　　I.主回路：电抗器的作用是防止变频器产生的高次谐波通过电源的输入回路返回到电网从而影响其他的受电设备，需要根据变频器的容量大小来决定是否需要加电抗器；滤波器是安装在变频器的输出端，减少变频器输出的高次谐波，当变频器到电机的距离较远时，应该安装滤波器。虽然变频器本身有各种保护功能，但缺相保护却并不完美，断路器在主回路中起到过载，缺相等保护，选型时可按照变频器的容量进行选择。可以用变频器本身的过载保护代替热继电器。

　　II. 控制回路：具有工频变频的手动切换，以便在变频出现故障时可以手动切工频运行，因输出端不能加电压，固工频和变频要有互锁。

　　4） 变频器的接地；

　　变频器正确接地是提高系统稳定性，抑制噪声能力的重要手段。变频器的接地端子的接地电阻越小越好，接地导线的截面不小于4mm，长度不超过5m.变频器的接地应和动力设备的接地点分开，不能共地。信号线的屏蔽层一端接到变频器的接地端，另一端浮空。变频器与控制柜之间电气相通。
