摘要
鉴于互连系统中电缆的电磁干扰问题,本文首先论述了由传输线理论对同轴电缆串扰的计算仿真,进而根据此模型自制了同轴电缆电磁耦合测试装置,测试若干结构参数对同轴电缆串扰电压的影响,得出了同轴电缆间串扰电压大小随电缆长度,干扰源电压和频率的增大而增大,最后比较仿真结果和测试结果,基本上达到了很好的一致性,此测试方法和结论对电气工程师测试和解决电缆串扰问题具有一定的实用价值。
Aiming at electromagnetic Interference of cable in interconnected systemε-this paper simulated and computed the crosstalk of coaxial cabie, baaed on the transmission line theory. Besides, a testing thlngamy that can test electromagnetic coupling between coaxial cables was made, in the hope of testing several struotural parameters which affect the tength, voltage of interference source and frequency.Comparing the records,the testing result shows good consistency with that of the simulation,this method and conclusion should be useful for electrical ongineer to test and solve crosstalk between cables.
