摘要
ZPW-2000系列轨道电路在高铁系统中广泛应用,雷击故障是影响其正常工作的因素之一,轨道电路室内外分界面是防雷的重点。从轨道电路雷击故障的实际出发,提出采用轨道电路专用防雷柜的方式解决室内外电缆长距离并行敷设问题,并且专用防雷柜的防雷性能相较于接口柜有一定的提升。
ZPW-2000 series track circuits are widely used in high-speed railway systems.Lightning strike failure is one of the factors aff ecting their normal operation.The indoor and outdoor interface of track circuits is the key point of lightning protection.Based on the reality of lightning strike faults in track circuits,this paper puts forward the method of using special lightning protection cabinets for track circuits to solve the problem of long-distance parallel laying of indoor and outdoor cables,and the lightning protection performance of the special lightning protection cabinets is improved to a certain extent compared to interface cabinets.
