摘要
测量不同长度MHYV7/0.37矿用通信电缆在1 kHz～5 MHz的衰减数据,比较衰减模型与实测衰减数据,结果表明衰减模型与试验数据具有良好的一致性;用无损耗传输线理论分析衰减模型和实测数据在特殊频点的波动现象,并且与理论分析保持一致,验证了所建立的衰减模型的准确性,从而验证了所建立的矿用通信电缆基本电气参数数值模型是正确、有效的。提出的建立矿用通信电缆基本电气参数模型的方法可以应用到其他电缆型号,为进一步研究矿用通信电缆的远距离传输特性提供了理论支持。
The attenuation data of MHYV7/0.37 communication cables with different lengths from 1 kHz to 5 MHz are measured,and the attenuation model is compared with the measured attenuation data.The results show that the attenuation model has a good consistency with the experimental data.The attenuation model and the fluctuation phenomenon of measured data at special frequency points are analyzed with the lossless transmission line theory,and the attenuation model is compared with the measured attenuation data.The theoretical analysis is consistent,which verifies the accuracy of the attenuation model,and thus verifies the correctness and validity of the established numerical model for basic electrical parameters of mine communication cables.The method of establishing the basic electrical parameters model of mine communication cable can be applied to other cable types,providing theoretical support for further research on long-distance transmission characteristics of mine communication cable.
