Transmission Line Icing Monitoring Device Based on Rotating Reference Conductor

Abstract

The present invention provides a transmission line icing monitoring device based on a rotating reference conductor, which at least includes a reference conductor, a suspension bracket and a tension sensor, the reference conductor is connected to the tension sensor in a rotatable manner, and the tension sensor is connected to the suspension bracket Fixed connection, the reference conductor is provided with an ice-melting unit; its reference conductor rotates under the action of wind force and ice coating gravity to form a uniform cylindrical ice coating on the surface of the reference conductor, and then monitor the quality of the ice coating through a tension sensor The simulated monitoring of the icing of the transmission line can effectively monitor the icing of the transmission line, effectively avoid the influence of the environment on the monitoring results, and greatly improve the accuracy of the icing monitoring.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to an ice-covered monitoring device for transmission lines based on a rotating reference conductor. Background technique [0002] In the environment of low temperature and high humidity in winter, high-voltage power transmission lines will be covered with icing. Severe icing will lead to major accidents such as the collapse of transmission line towers and broken wires that affect the safe and reliable operation of the power system, causing large-scale power outages in the power grid. Seriously affect industrial and agricultural production and people's lives, and cause huge economic losses. [0003] At present, there are mainly methods of monitoring icing on transmission lines, such as video monitoring and manual line inspection. The video monitoring method is to obtain the icing image of the transmission line through the camera and process it, and extract the boundary contour to esti...

Problems solved by technology

The video monitoring method is to obtain the icing image of the transmission line through the camera and process it, and extract the boundary contour to estimate the ice thickness on the transmission line. However, there are many difficulties in the actual application of the video method. The quality of the monitoring system used in the video monitoring method The size of the camera is large, the installation angle of the camera is demanding, and it is easy to cause distortion of the monitoring image. Especially when the icing is serious, the camera is covered by ice and snow and it is difficult to capture the icing of the transmission line. As a result, the accuracy of this method for icing detection is extremely low or even impossible to monitor. , while high-definition cameras are expensive and costly

Manual line inspection is to measure the icing situation of transmission lines through the on-site observation of inspectors, but because the icing of transmission lines is greatly affected by local micro-topography and climate conditions, and some lines are erected in sparsely populated areas with inconvenient transportation, this aspect greatly increases It reduces the labor intensity of inspectors, and on the other hand, it also reduces the timeliness and accuracy of monitoring results.
