| 摘 要： | 通过用不同的测温计测量老旧导线和新导线的温度,在室内模拟架空输电线路的运行状态,对比分析了阳江35 kV老旧导线与未服役的新导线的载流温升性能。由理论分析,发现老旧导线的辐射散热功率高于未服役新导线,未服役新线的辐射散热功率比老旧导线少46%左右;由试验结果分析得出:LGJ70/10导线在相同的电流值下,未服役新导线的温升比老旧导线的温升低11%左右。

| Abstract: | By using different thermometers to measure the old and the new conductors＇ temperature,by simulating the overhead transmission lines＇ running indoor,and comparative analysis of the performance of the carrier temperature of Yangjiang 35 kV old conductors and new ones. By the theoretical analysis,we found the old wires＇ radiated heat power higher than the new conductors. The heat radiated power of the new conductors are less than about 46% of the old ones; Analysis of test results obtained by the wire at the same current value,the new LGJ70 /10 conductors service temperature is lower than the old ones about 11%. |
