轮式拖拉机电磁兼容性试验研究

Testing Study on Electromagnetic Compatibility of Wheeled Tractor

针对国产某型轮式拖拉机出口认证检测中电磁窄带发射超标和电磁辐射抗扰度不合格的问题,通过试验研究,找出了导致整机不合格的部件,并对其重新进行了电磁兼容设计;经过试验验证,整改后的拖拉机的电磁窄带发射和抗扰度均符合标准要求。

Aimed at the problem that narrowband radiation and electromagnetic immunity of a domestic wheeled tractor exceed the limits, the unqualified part is found out through testing study. The method of improving the electromagnetic compatibility is presented and verified using test. The results show that electromagnetic narrowband radiation and immunity of the improved tractor can conform to the standard requirements.
