| 摘 要： | 输电线路短路融冰是目前最为有效的一种除冰方法,而融冰过程中导线温升过快可能会超过导线允许温度使导线损伤。为此,以LGJ-240/30和LGJ-400/35导线为试品,在人工气候室进行了大量的融冰试验。试验结果表明,融冰过程中,导线表面最高温度决定于冰层厚度和融冰电流的大小,不受外界环境温度和风速的影响。并推导出导线最高温度的计算公式。

| Abstract: | Ice-melting with short-circuit in transmission line is the most effective methods of de-icing.Conductor would be damaged if rapidly rising conductor temperature exceeds the allowable temperature.A lot of laboratory experiments were carried out on both LGJ-240/30 and LGJ-400/35 conductor in the artificial climate chamber.The tests results and analysis show that the maximum temperature of conductor is determined by two factors including the thickness of ice and ice-melting current,and is not influenced by amb... |
