| 摘 要： | 为研究交联聚乙烯单芯电缆的护套环流,建立了计算单芯电缆金属护套两端互联直接接地以及交叉互联两端接地时环流的数学模型,编写VB程序进行了计算。在实际电缆线路上的试验结果与计算值相差不大,验证了编程计算的正确性。讨论了各种因素对护套环流的影响后提出了串入电阻以有效降低环流的思路。

| Abstract: | The paper presents a model of calculating so-called circulating current of cable (CCA) consisting of three single-core XLPE cables, of which sheaths are two-end grounded. Taking the induced voltage into consideration, both of sheaths with or without applied cross-bonding connection are discussed here. A programmer is tested for calculating the circulating current, and the result is compared with experimentation to prove the correctness of the calculation. Meanwhile, the influential factors of circulating current are discussed, and a new method to reduce the value is presented. |
