用概率法确定送电线路对电信线路的危险影响程度

Determination of Dangerous Influence Degree of Transmission Line on Telecommunication Line by Probabilistic Method

针对送电线路故障率 ,用概率分析的方法研究了送电线路对电信线路造成损害的故障率以及这一故障率的最小值。当电信线路上感应电压超过某允许值的概率小于造成危害的最小概率时 ,可认为其不对电信线路造成损害 。

Aimed at the failure rate of transmission line,the dangerous influence degree of transmission line on telecommunication line and its minimum value are determined by probabilistic method.When the probability that the inductive voltage is more than allowable value is small than the minimum,the failure of transmission isnt harmful to the telecommunication line.The protection is not need to be used.
