应用传输线理论建立矿用双绞线的RLCG模型,研究了浪涌耦合到矿用双绞线后,浪涌的传输特性。选取了MHYVP 1/1.38、MHYBV 1/1.0和MHYV 7/0.28三种典型矿用双绞线进行了数据建模和仿真计算,研究结果表明浪涌脉冲耦合到矿用双绞线会产生较强的骚扰电压,线缆的长度和频率会影响浪涌骚扰电压的幅值和相位,双绞线越长,频率越高,骚扰电压衰减越快。MHYVP 1/1.38型抗浪涌骚扰特性最差,MHYBV 1/1.0型次之,MHYV 7/0.28型最好。

英文摘要：

Based on the transmission line theory, the RLCG models of mine cable were con- structed and the propagation law of electromagnetic disturbance caused by surge in mine cable was studied. The RLCG models were tested for three typical mine cables by numerical simulation. The results show that the surge injection into the mine cable produced high disturbance voltage. The length and freguency of the twisted-pair influenced the transmission of the surge disturbance voltage. The longer cable and higher trequency led to greater attenuation. From the analyzsis of the transmission characters of surge turbulence in three typical mining type twist cables,including MHYVP 1/1.38,MHYBV 1/1.0 and MHYV 7/0.28,it is found that MHYVP 1/ 1.38 mining type twist cable had the worst anti-disturbance character, MHYBV 1/1.0 was better and the MHYV 7/0. 28 was the best of all.
