Abstract

In the method and device for monitoring the safe distance between the drainage line and the tower provided by the application, a plurality of different micro-topographic micro-meteorological models and tower models are established, and by adjusting the wind speed, wind direction, voltage and current until the drainage line discharges, the obtained Under different micro-terrain and micro-meteorological models, the critical conditions for the discharge of the diversion line of the tower under different wind speeds, wind directions, voltages and currents, etc., and then obtain the distance between the diversion line and the tower at the moment of discharge of the diversion line, by drawing the wind speed, voltage and the three-dimensional graph of the distance, the area formed by the voltage, wind speed and the distance between the drain line and the tower on the graph is the distance between the drain line and the tower that can be selected under the voltage and wind speed The distance is the safe distance between the diversion line and the pole tower, and the safety distance can provide a reference basis for the line design unit on the distance between the diversion line and the pole tower, so as to ensure the safety of line operation.

Description

technical field [0001] The present application relates to the technical field of transmission line monitoring, in particular to a method and device for monitoring a safety distance between a diversion line and a pole tower. Background technique [0002] As an important part of the power system, the overhead transmission line is outdoors all the year round, and the line is easily affected by the external environment in normal operation, especially under the micro-topography and micro-meteorological conditions, the drainage line of the transmission line is likely to cause wind deflection under the condition of strong wind. The safe distance between the drainage line and the tower is the critical point for determining the wind deflection flashover, that is, the discharge of the drainage line can be avoided when the distance between the drainage line and the tower is within the safe distance under different micro-topography and micro-meteorological conditions phenomenon, which c...
