摘要
为了提高交流电缆载流能力的利用率,提出交流电缆稳态载流量计算相关可变参数的监测方案.根据IEC-60287标准,应用变化单一参数,固定其他参数的方法,分析环境温度、土壤水分迁移、土壤热阻系数、电缆敷设深度以及电缆排列方式对稳态载流量计算的影响.结果表明,各监测量对于稳态载流量计算结果的影响规律并不完全一致,具有各自的特点.
To enhance the availability of current-carrying capacity of AC cables, a monitoring method of alterable parameters of steady-state current-carrying capacity of AC cables is put for ward. The method of changing single parameter while fixing others is used to analyze the influence of environmental temperature, soil moisture, soil thermal resistivity, laying depth and ar- rangement on computing result of steady-state current-carrying capacity based on IEC-60287. The results point out that the influence rules of parameters are not the same and they are u- nique in their own features.
