摘要
对2010年2月中旬粤北电网坪通线及其84号监测点覆冰发生情况进行了详细介绍和分析,所得结果证明覆冰监测网监测覆冰产生、覆冰迅速增加、覆冰稳定、覆冰融化4个阶段与气象条件的变化相吻合,监测的覆冰信息、线路覆冰故障与现场观测结果一致,说明了覆冰监测网反映现场覆冰情况、线路覆冰故障及时可靠,对线路覆冰信息判断较为准确,运行可靠,为输电线路的防冰工作提供了可靠信息。
Detailed description and analysis are made on the icing condition of Pingtong Line and its No.84 monitoring point in north Guangdong power grid in mid-February 2010.Four steps of icing process determined by the icing monitoring network,i.e.formation,rapid growing,maintaining and melting,coincided with the weather changes in that period;the icing condition of the icing monitoring network reported also coincided with manual observation.It is proved that the icing monitoring network can reflect icing condition on-site and judge icing accidents of lines timely,accurately and reliably,thereby providing dependable information for deicing and ice melting of transmission lines.
