    為(wei)了(le)深入了(le)解煤礦井下電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)電(dian)(dian)磁騷(sao)(sao)擾(rao)(rao)的(de)傳(chuan)播(bo)(bo)規律,分析了(le)電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)的(de)頻(pin)譜特性,運用(yong)(yong)傳(chuan)輸線(xian)(xian)理論建立了(le)礦用(yong)(yong)線(xian)(xian)纜(lan)的(de)RLCG模型(xing),并利用(yong)(yong)PSPICE軟件進行仿真(zhen)分析,研究了(le)礦用(yong)(yong)線(xian)(xian)纜(lan)中電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)騷(sao)(sao)擾(rao)(rao)的(de)傳(chuan)輸特性.結果(guo)表明(ming):礦用(yong)(yong)線(xian)(xian)纜(lan)對(dui)電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)騷(sao)(sao)擾(rao)(rao)的(de)傳(chuan)播(bo)(bo)有一定的(de)抑制(zhi)作用(yong)(yong),線(xian)(xian)纜(lan)越長抑制(zhi)效果(guo)越明(ming)顯,騷(sao)(sao)擾(rao)(rao)電(dian)(dian)壓(ya)頻(pin)率越高衰減越快;井下雙絞(jiao)線(xian)(xian)傳(chuan)輸距離(li)超過(guo)1 km后,電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)騷(sao)(sao)擾(rao)(rao)最(zui)大值衰減為(wei)5.665 nV,遠距離(li)傳(chuan)輸信(xin)號時可以(yi)不考慮(lv)騷(sao)(sao)擾(rao)(rao)的(de)影響;電(dian)(dian)快速(su)瞬變(bian)脈沖(chong)群(qun)騷(sao)(sao)擾(rao)(rao)主要是以(yi)共(gong)模形式(shi)傳(chuan)播(bo)(bo),井下電(dian)(dian)子(zi)設備(bei)需要采取相(xiang)應的(de)共(gong)模干(gan)擾(rao)(rao)抑制(zhi)措(cuo)施;礦用(yong)(yong)電(dian)(dian)子(zi)設備(bei)多為(wei)本(ben)質(zhi)安全型(xing)防爆(bao)設備(bei),抗(kang)擾(rao)(rao)度實驗等級(ji)應定為(wei)3級(ji)。
