| 摘 要： | 在计算电缆群载流量时,交流电阻是一个重要的参数,其中邻近效应是计算交流电阻的一部分.IEC-60287和JB/T10181-2000仅给出了单回路情况下的邻近效应计算公式,且有一定的限制条件.本文利用电磁场理论和贝塞尔函数计算任意电缆群的邻近效应,给出了不同相位排列方式下的结果,并给出了电缆邻近效应最小时的相位排列方式. |
| 关 键 词： | 载流量 交流电阻 邻近效应 贝塞尔函数 |

| Abstract: | AC resistance of cable conductor is an important factor to calculate the ampacity of cable bundles, and proximity effect factor is an important parameter to affect AC resistance. IEC-60287 and JB/T10181-2000 give only a formula to calculate the proximity effect of single loop cable conductor, and there are some limiting prerequisites to use the formula. On the basis of electric and magnetic field theory, the paper presents a common calculation formula which can be used to calculate the proximity effects of any cable bundles. This formula is obtained by solving the magnetic vector equation with Maxwell equation and Bessel function. As examples, the paper calculates the proximities of different phase arrangement and gives a phase arrangement which proximity is the least in three laying modes. |
| Keywords: | ampacity AC resistance proximity effect Bessel function |
