使用金属导体的电信线路抗雷电保护 – 风险管理 |
ITU-T K.72建议书给出了评估方法,以评估采用金属导体的电信线路抗雷电影响的保护措施的必要性。该方法基于风险评测:当风险大于可容忍风险时,必须采取保护措施。建议的可容忍风险最大值已经给出。本建议书考虑了电信网络业务损失的风险。该风险的评估是通过雷击造成的风险组件实现的,而后者是电信线路损毁的来源,而雷击可以看作是电信线路的函数的转折点(雷电直接发生在电信线路上或线路附近,或直接发生在与电信线路终端相连的结构上)。本建议书应与ITU-T K.47建议书一并使用,以提供有关雷击直接在电信线路和相连结构上发生时的风险评估和防护措施,而ITU-T K.46提供了雷击在电信线路附近发生时的风险评估和防护措施。 |
