Description

Power transmission line tower pole anti-falling detection early warning system and detection method

Technical Field

The invention relates to the technical field of transmission line safety, in particular to a system and a method for early warning of anti-falling detection of a tower pole of a transmission line.

Background

Line tripping caused by windage yaw flashover of a power transmission line is one of important factors influencing normal operation of the power transmission line. According to statistical data, most of tripping accidents of power transmission lines in China are caused by windage yaw of insulator strings in the lines, the suspended insulator strings of the power transmission lines are easy to displace under the action of wind load, lower-end leads are driven to displace, the distance between the leads and tower poles is reduced, namely, air gaps are reduced, when the tolerance voltage of the air gaps is smaller than the operating voltage of the lines, the voltage of the lines can break through air, the electric wires and the tower poles are discharged, and therefore electric energy loss, line tripping and other dangers occur, serious conditions even the normal operation of local power grids is influenced, and great electric energy and economic loss are caused. The reason for the operation fault of the power grid caused by windage yaw flashover in recent years can be analyzed, and the reasons influencing the windage yaw are many and comprise internal reasons and external reasons, wherein the internal reasons mainly comprise the span, the span number, the lead type, the line included angle line operation voltage and the like of the power transmission line, and the external reasons mainly comprise wind load, terrain height difference and the like. And when the transmission line has windage yaw flashover to cause the line to trip, the closing rate of the line is very low, and the transportation efficiency of electric energy is seriously reduced.

Besides wind drift flashover, the tower collapse accident also greatly threatens the safe power supply of the power transmission line along with the frequent occurrence of strong convection weather such as strong wind and the like, and also causes great loss. Through incomplete statistics of 220KV lines in China, the average pole-falling rate is 0.01 time per hundred kilometers per year in nearly 15 years, and the value is obviously higher than that in Europe and America. Through analysis, the basic reason that the tower rate of the pole falling tower is high is that the actual wind resistance level of the tower is lower due to the fact that the dynamic effect of gust, namely wind vibration, is not considered by wind load, and in addition, the tower rate of the pole falling tower is also increased due to factors such as structural strength, wind power and landform of the tower. The characteristics of the inverted pole tower of the ultra-high voltage transmission line are deeply researched, and the research on risk assessment and early warning methods of the inverted pole tower of the ultra-high voltage transmission line is imperative.
