Description

Technical Field

[0001] The present invention relates to the technical field of ice coating detection, and in particular to an ice coating detection device for overhead line transmission lines. Background Art

[0002] The icing detection device for overhead power transmission lines is a device used to monitor the ice on the surface of power lines. As the temperature drops and the humidity increases, the overhead power lines may increase the load due to the accumulation of ice and snow, and even cause line breakage or equipment damage. The device uses sensors installed on the transmission lines to monitor the temperature, humidity and other environmental parameters of the lines in real time to determine whether there is icing. The data is transmitted to the monitoring center wirelessly or wired for analysis and decision-making by operation and maintenance personnel. Once icing is detected, the system will issue an alarm in time to prompt the staff to take measures, such as de-icing or adjusting the load. The application of this device can effectively improve the safety and reliability of transmission lines, reduce the risk of power failures caused by weather factors, and ensure the stable operation of the power system.

[0003] At present, when the existing ice detection device is in use, since the ice detector and the line installation component adopt an integrated structural design, although this design can enhance the stability of the connection between the two, but in actual application, the operations of disassembly, maintenance and replacement of the ice detector and the line installation component are subject to certain restrictions, and the existing line installation components cannot be flexibly adjusted to meet the needs of different thickness specifications when installing the transmission line, which to a certain extent affects the stability of the line installation components to the transmission line installation, so there are certain limitations in use.

[0004] Based on this, we propose an ice detection device for overhead line transmission lines to solve the above-mentioned problems. Summary of the invention
