Embodiment Construction

[0021] Concrete method of the present invention is as follows:

[0022] 1) Collect data on the tensile force borne by insulators or insulator strings connected to the upper and lower fittings, as well as the wind speed and direction acting on the tower;

[0023] 2) According to the collected data of wind speed and wind direction, as well as the parameters of guide and ground wires of different cross-sections and different combinations, the wind pressure values ​​on the guide and ground wires are obtained;

[0024] 3) According to the wind pressure value and the collected tension data, the derivation, ground wire ice thickness and weight are calculated through statistical calculation.

[0025] see figure 1 , the measurement system of the present invention comprises a tension measuring device 1, an anemometer 2, a wind direction measuring device 3 and a central data processing device 5, the tension measuring device 1 is connected in series with an insulator string or a fitting ...

Abstract

The invention relates to a method for measuring the ice thickness of span wire and earth cord, and relative system. Said method comprises: 1, collecting the drawing forces on the connecting elements of insulator or the insulated sequence and the wind speed and direction on the iron tower; 2, according to the collected data and the parameters of the wire and earth cord in different sections and integrations to attain the wind pressure on the wire and earth cord; 3, according to the wind pressure and collected drawing force, via stat calculating the ice thickness and weight of wire and earth cord. The invention can measure the ice thickness and weight of wire and earth cord.

Description

1. Technical field [0001] The invention relates to a measuring method and a measuring system, in particular to a method and a measuring system for measuring the thickness of the ice-covered conductor and ground wire of an overhead power transmission line. 2. Background technology [0002] The temperature in winter in our country is low, and there are frequent rain, snow and foggy weather. Therefore, there will be different degrees of ice coating on the power transmission lines, insulator strings and tower bodies. Jumping and dancing will have a strong impact on the iron tower. When the dynamic and static loads exceed the design bearing capacity of the iron tower, an accident of line disconnection and tower collapse will occur. In recent years, due to the icing of the tower body, guides, ground wires, and line dancing, accidents of line disconnection and tower collapse have occurred from time to time, causing huge direct and indirect economic losses to the power system and pe...
