Portable icing observer and method for measuring icing thickness of overhead transmission lines

Abstract

The invention aims at providing an accurate and portable device for measuring the ice coating thickness of a power transmission line, and particularly relates to a portable ice coating observation instrument for measuring the ice coating thickness of an overhead power transmission line. The portable ice coating observation instrument comprises a laser distance-measuring device and an optical measuring device, wherein the optical measuring device comprises an observation eye lens and an object lens, and a cross division measuring plate is arranged between the observation eye lens and the object lens; and the laser distance-measuring device comprises a laser transmitting / receiving device. In the process of measuring the ice coating thickness of the overhead power transmission line, a more accurate distance value is obtained by measuring the distance between an ice coating point and an observation point of the overhead power transmission line by utilizing the laser distance-measuring function of an imaging device with the laser distance-measuring function; then a more accurate mil value is obtained by reading a mil number occupied by the coated ice of the overhead power transmission line by utilizing the cross division measuring plate of the imaging device with the laser distance-measuring function; and finally a more accurate ice coating thickness value of the overhead power transmission line can be obtained through an inversion mil distance-measuring principle.

Description

technical field [0001] The invention relates to the field of electrical engineering, in particular to the observation of the ice thickness of overhead transmission lines. Background technique [0002] In the past few years from January 2008 to the present, there have been long-term, continuous, high-intensity and large-scale low-temperature rain, snow and freezing weather in parts of central China, east China, and southwest my country, resulting in Jiangxi, Hunan, In Hubei, Zhejiang, Anhui and other places, a variety of serious ice-covered disasters, such as collapsed towers, disconnected lines, dancing lines, and ice flashes, occurred one after another. The occurrence of these disasters caused economic and property losses of power grid companies as high as more than 100 billion yuan. For severe icing disaster accidents, fine division of ice areas on transmission lines to guide differentiated anti-icing transformation work, and deicing work on transmission lines are effectiv...
