变频器使用中的干扰与抑制

Interference and anti-interference of the VF controlling in manufacture

变频器在实际生产应用中常会出现干扰问题,干扰不仅是外部对变频器的干扰,而且同时存在变频器自身对外部的干扰,这使变频器和变频器周边的设备都不能正常工作。笔者根据实践中的一些体会,提出解决变频器干扰问题的一些方法。

VF controlling appears same problems on occasion in practice. The great deal of and chief questions are interference. Not only the interference comes from the peripheral system. But also VF controlling badly impact to peripheral system. If we can not solve the problem. VF controlling and peripheral system both may be out of control. This paper introduces some methods of anti-interference technique bases of individual experience.
