    接地引出装置可有效防止地下水渗漏,并在地铁站台上连接动力设备接地,信号设备接地,防雷接地和综合接地网时满足杂散电流保护的要求。在地铁接地系统中,由于对故障电流(杂散电流)的保护要求,接地网位于其结构底部下方。因此,将地铁平台上的电气设备接地时,必须通过接地引出线将其连接到接地网,以实现可靠的接地。过去,接地线通常直接从结构底板或通过PVC管引出。通过这种措施,很容易无法满足故障电流(杂散电流)的保护要求,地下水很容易从接地线中漏出,不能满足地铁接地的设计要求。接地引出装置由保护筒,止水环,接地引出线,绝缘填充材料等组成。保护管由不锈钢制成,接地线由T2铜制成,保护管的中空部分填充有绝缘材料,具有选材科学,结构电力设备,信号设备和防雷设备的地面与地铁站台上的综合接地网相连时,可有效防止排水渗漏,并能很好地满足故障电流(杂散电流)保护的要求。接地引出装置的类型:管体引出线的类型H /毫米d /毫米S /毫米L1 /毫米L2 /毫米ZH-R 108 * *一三零零年至1350年(400 + 300)1300108 50 * 5400300 ZH-R 108 * 1500-50 * 5 *(400 + 300)1500108 50 * 5400300 ZH-R 108 * 1650-50 * 5 *(650 + 600)1650 50 * 5650 * 600
