摘要
以导线悬挂点倾角监测装置及拉力传感器为监测工具,结合档内导线最大弧垂及线长计算,推导出一种适用于耐张式连接的导线标准覆冰冰重模型,可在有限的监测条件下对架空导线覆冰状况进行准确的判断,模型无需依赖大量经验数据,也无需对繁杂的气象因素作监测,具有较好的经济性与实用性。
By using the obliquity monitor device and the pull sensor at the hanging point of the conductor and combining calculations on the maximum sag and length of the conductor within the span, a standard model for calculating the weight of ice accretion on conductors was deduced which can be used to accurately judge the ice accretion situation for overhead lines under limited monitoring conditions. What＇ s more, the practical model does not need large amount of experiential data and complicated weather factors.
