摘　　要：为充分发挥电力电缆的裕量,同时确保电缆安全运行,讨论了内嵌式光纤电力电缆原理,并进行了66 k V1×1 200 mm2XLPE电缆试验研究。试验结果表明,缆芯、光纤误差均在2.5℃以内。同时也证明了有限元模型的正确性,以及内嵌式光纤测温技术具有误差小、精度高、运行可靠等特点。In order to make full use of power cable allowance, and to ensure the safe operation of the power cable at the same time, this paper discusses the principle of power cable based on embedded fiber, and carries out the test to verify the result of calculation of a 66 kV 1 × 1200 mm2 XLPE cable. The experimental results shows that it is confirmed that errors of cable and fiber are within 2. 5℃, the finite element model is accurate and it enjoys the advantages of the embedded fiber temperature sensing, such as small error, high accuracy and high reliability.
