Abstract

The invention discloses a wind field simulation device for a guide line galloping test. At present, researches on the guide line galloping test are very few, and a small amount of undertaken researches on the guide line galloping test are mainly carried out in a wind tunnel or on a test line; the galloping test carried out on the test line utilizes natural wind; the wind simulation device utilized by the galloping test in the wind channel is complex in structure and higher in cost. The wind field simulation device is characterized by comprising an expanding entrance, a rectification section, a contraction section, a test section, a zig-zag type contraction section and a power section which are spliced with each other in sequence from left to right; besides, the wind filed simulation device enables the airflow performance to be relatively stable, can meet the requirement of the guide line galloping test, and is simple in manufacturing technique and lower in cost.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to a wind field simulation device for the galloping test of the conductors of the power transmission line. Background technique [0002] There are many factors affecting conductor galloping in transmission lines, and the formation mechanism is complex. Conductor galloping test research plays an important role in theoretical verification and dynamic parameter acquisition. At present, the galloping research of wires is mainly theoretical simulation research, and there are few galloping test studies. The few galloping test studies that have been carried out are mainly carried out in wind tunnels or on test lines. The galloping test on the test line uses natural wind; the wind simulation device used in the wind tunnel test has a complex structure and high cost. [0003] In order to facilitate the research of conductor galloping experiments in the laboratory, study the influence...
