Abstract

The invention relates to a device and a method for measuring the ice accumulation on an electrical wire. The device comprises a camera, a lighting device, a microprocessor and a storage unit, wherein the camera is arranged below an electrical wire to be measured between two electric poles and is used for collecting images of the electrical wire to be measured before and after icing, and the images are sent to the storage unit by a data line; the lighting device is arranged below the electrical wire to be measured between the two electric poles and is used for lightening the image collection area of the electrical wire to be measured above the camera; the microprocessor comprises an arithmetical unit for measuring the image data and calculating the thickness of the ice accumulation on the electrical wire and a controller for controlling the operation of the camera, the storage unit, the lighting device and a communication transmitting device, and the communication interface of the microprocessor is connected with the communication transmitting device; and the storage unit is used for storing the image data and the calculation formulas. The device can conveniently and fast detect the thickness of the ice accumulation on the electrical wire, provide caution to the operation unit, and have the characteristics of simple structure, low cost, accurate measurement, security and convenience. Besides, the steps of the method are simple, and the measurement result is true and reliable.

Description

technical field [0001] The invention relates to a device for measuring the thickness of ice accumulation on outdoor electric wires and a measuring method thereof. Background technique [0002] In most parts of my country, the winter temperature is below zero, and rain and snow often occur. Therefore, there will be different degrees of ice accumulation on the wires of outdoor high-voltage overhead transmission lines. If the ice accumulation exceeds the design standards of high-voltage overhead transmission lines, it will Accidents of broken wires and collapsed utility poles occurred, resulting in circuit interruption and damage to grid lines, which brought troubles and immeasurable economic losses to people's lives. [0003] With the development of society, there are more and more high-voltage overhead power transmission lines, and the risk of wire disconnection due to ice and snow is also increasing. Therefore, the operating unit needs to take various measures to eradicate th...
