变频器干扰怎么办/如何解决

变频器干扰比较常见,由于变频器生产厂商质量掺杂不齐导致干扰的比较多见。
下面我们谈谈变频器干扰怎么办/如何解决。
一、电网线路系统干扰
一般由变频器产生高次谐波及杂波污染电网导致线路上其他设备异常。解决办法
正确接地让设备都可靠接地，在变频器输入输出端加进线滤波器和输出滤波器如滤波电容和电抗器。
在其他电子仪表供电电源加上隔离变压器可以有效减少电源干扰。
当然了在条件允许的情况下，在复杂工况条件下，问题不是绝对的要综合思考。
二、输出信号干扰
在变频器信号输出端加上信号隔离器能有效解决干扰，当然了看变频器干扰程度了有些垃圾变频器是没法解决的。
三、高频信号空间干扰
这个是最难解决的一般情况将设备可靠接地通信线路采用高通金属屏蔽双绞线进行屏蔽。有的情况是变频器达到一定强度的干扰这些措施形同虚设。唯一的方法果断跟换变频器不要盲目相信什么大品牌那也是人生产出来的。
四、 通信干扰
这个问题比较复杂，我个人认为这个问题主要是变频器生产厂家干扰处理不好带来的还有就是其他产品未做隔离通信处理。一般情况各类仪表通信模块都是采用的光电隔离通信模块这个基本是不可能通过通信电缆干扰的。
综上所述，遇到干扰问题要先确定干扰源的干扰性质由什么产生的干扰 有条件最直接的办法就是跟换其他品牌变频器试试来确定问题出在拿出相应解决办法不要惊慌冷静思考就跟医生看病一样问题只有一个，但解决的方法多样。

Drive disturbance relatively common , because the quality of the inverter manufacturer doping missing more common cause interference .
Here we talk about how to do the inverter interference / how to solve.
A grid line system interference
Generally higher harmonics generated by the inverter noise pollution and cause other devices on the power line anomalies. Solution
Let devices are properly grounded and reliable grounding , plus the output of the inverter input and output filter line filter as filter capacitors and reactors .
Plus isolation transformer power supply in other electronic instruments can effectively reduce power noise .
Of course, under the conditions permit , under complex operating conditions , the problem is not to be absolutely comprehensive thinking.
Second, the output signal interference
In the inverter output signal plus signal isolation can effectively solve the interference, of course to see the extent of the interference of some garbage drive inverter is impossible to solve.
Third, the spatial high-frequency interference signals
This is generally the most difficult to solve reliable grounding device communication lines using Qualcomm metal shielded twisted pair shielded . There were cases when the drive reaches a certain intensity of the interference of these measures useless. The only way to decisively change the drive with the big brands do not blindly believe that is what people produced.
Fourth, communication interference
This problem is more complex, I personally think that this problem is handled inverter manufacturer there is interference of other products without making a bad deal to bring isolated communications . Generally all types of instruments are used in optical communication module communication module isolation is not possible through this basic communication cable interference.
In summary, interference problems encountered interference should determine the nature of the source of interference by the most direct way to interfere with what is produced is conditional with the drive for other brands to try to determine the problem is to come up with appropriate solutions do not panic calm just thinking the same doctor is only one problem , but the solution methods varied.
