Abstract

The invention discloses a wind tunnel test system and method for simulating continuous collapse of a power transmission line, and relates to the technical field of power transmission line wind resistance, the wind tunnel test system comprises a four-base power transmission tower and a three-span wire ground wire, the four-base power transmission tower comprises two-base boundary towers and two-base middle towers, and one-base middle tower is a complete aeroelastic model and used as a test target tower; the other base middle tower is an equivalent bracket tower and is used as a weak tower which can be collapsed in the test; every two adjacent power transmission towers are connected through the wire ground wire. and the test points are arranged on the target tower and the key nodes of the wire ground wire. The power transmission stability of an existing power transmission line can be improved, and economic losses caused by secondary tower collapse are reduced.

Description

technical field [0001] The invention relates to the technical field of wind resistance of transmission lines, in particular to a wind tunnel test system and method for simulating continuous collapse of transmission lines. Background technique [0002] Power grid is an important lifeline project, and its safe operation is the basis for the normal operation of various industries and institutions. In the event of a transmission tower collapse accident, due to the time-consuming restoration and reconstruction work, it often causes a long-term power outage in some areas, which seriously affects normal life and production. Therefore, wind-induced tower collapse accidents on transmission lines usually lead to huge economic losses. [0003] In the transmission line, the collapse of one base transmission tower will increase the instability of the overall transmission line and increase the probability of continuous collapse of multi-base transmission towers. The analysis of the vibra...
