Abstract

The invention provides a method and a system for determining the rain intensity of a corona cage raining device under a breeze condition. According to the method and the system, the method comprises:under the condition that wind exists, calculating the horizontal displacement of the raindrops under the action of horizontal wind; determining the positions of the water drops in the spray holes in the horizontal plane of the wire, determining the number of the spray holes for dropping the rain drops in the units with the same area divided by the horizontal line of the wire, and comparing the number with the number of the spray holes for dropping the rain drops in each unit in the absence of wind to determine the rain intensity of each unit in the horizontal line of the wire. According to themethod and the system, the inaccurate measurement result caused by monitoring the rain intensity only through 1-2 rain gauges under the corona cage in the prior art is well corrected. Therefore, themeasurement result is more objective and closer to the actual situation, more accurate reference data is provided for selecting a proper wire section and a configuration mode, and the environmental friendliness of power transmission and transformation engineering and the economical efficiency of engineering cost are facilitated.

Description

technical field [0001] The invention relates to the field of high-voltage testing of high-voltage power transmission and transformation projects, and more particularly, relates to a method and system for determining the rain intensity of a corona cage rain shower device under a breeze condition. Background technique [0002] The transmission line is an important carrier of ultra-high voltage transmission. When the voltage applied to the wire of the transmission line rises to a certain level and the surface electric field strength of the wire reaches the inception field strength, the air around the wire surface will be ionized and gas discharge will occur. That is, corona discharge. Corona discharge will generate radio noise and audible noise. When the radio noise exceeds a certain intensity, it will interfere with the surrounding radio services. If the audible noise exceeds a certain intensity, it will affect the acoustic environment along the line. Corona discharge will cau...
