基于输电线路导线悬点倾角与张力估算覆冰重量模型

A Model for Calculating Ice Weight on Transmission Lines Based on the Catenary Angle and Tension of Lines

为在有限的监测条件下对输电线路架空导线覆冰状况进行准确的判断,文中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。该模型根据架空线悬点处张力与倾角对覆冰导线冰重进行求解,具有较好的经济性与实用性。

In order to estimate the conditions of overhead wire icing under the limited monitor instrument accurately,in this paper,hanging point angle monitoring devices and rally sensors are used. The calculation of the largest wire sag and electrical wire longness of the wiring file are deducted. Finally,an model of icing wire weight applied to the strain-resistance wires was deducted. According to the rally and the angle of the icing wire hanging point,ice weight can be derived for the calculation. This model has good economy and practicability.
