Description

TECHNICAL FIELD

[0001] The utility model relates to power transmission line icing on line monitoring technical field especially a kind of multifunctional icing on line monitoring device. BACKGROUND

[0002] In cold winter, power transmission line is susceptible to icing, leading to line weight increase, line loss increase, and even line fault and power failure accident in serious case.Therefore, it is of great significance to monitor power transmission line icing on line.The traditional monitoring method, such as artificial line patrol, ice observation station, etc., is not only low in efficiency and time-consuming and labor-consuming, but also has safety hazard.

[0003] In recent years, there are some power transmission line icing on line monitoring devices at home and abroad, and its basic realization means can be divided into two kinds:one is the method based on mechanical monitoring model, and the real-time measurement data of insulator tension and insulator inclination angle are imported into relevant mechanical model to calculate icing condition, but most mechanical analysis models are only calculated under static measurement mode, ignoring the influence of other objective factors such as conductor wind deflection and uneven icing distribution.The other is the method based on simulation measurement, which estimates the actual conductor icing thickness condition by collecting the icing thickness condition on microwave sensor through microwave icing sensor or estimates the actual conductor icing thickness condition by collecting the weight of a section of simulated conductor through small tension sensor.

[0004] The disadvantages of the above two icing monitoring methods are that, first, the equipment accessories are many, including host or sensor support, etc., and the installation is complex, which brings certain risk to construction safety;Second, the function and monitoring range are relatively single, mainly for icing thickness estimation and environmental meteorological (surrounding temperature and humidity) monitoring, and the operation condition of power transmission line conductor itself is hardly monitored.
