摘要
为有效保护铁路信号设备,满足雷电侵入时的防护需要,对信号电源系统和计算机通道建议采用多级防护。各级防雷器件间能量需协调配合,以便每个防雷器间能量配合合理有效。讨论了能量配合原理和要求,并针对铁路现场操作过电压的情况,对电源防雷箱内防雷器的后备保护措施提出了要求建议,希望生产厂家对现场的实际情况予以注意。
To effectively protect the railway signal device and to meet the needs of protection in the case of lightning invasion, the multi-tier protection for signal power systems and computer in- ter{ace is recommended. This paper discusses the principle and requirement of energy cooperation in multi-tier protection. According to the condition of over-voltage for railway on-site operating, some suggestion and requirements is put forward for standby protection measures of lightning protection device in power lightning protection box. It is suggested that manufacturer pay close attention to the actual situation.
