Abstract

The invention discloses a support tower device and method for simulating collapse of a power transmission tower in a wind tunnel test, and relates to the technical field of wind resistance of power transmission lines. The support tower device comprises a support tower device body, a collapse triggering device and a limiting control device, and the support tower device body serves as an equivalent reduced scale support model of the power transmission tower body in actual engineering; the collapse triggering device is used for triggering the lateral displacement direction and moment of the support tower device body; and the limiting control device is used for controlling the amplitude of the support tower device body during lateral displacement. According to the support tower device and the method, different tower falling directions and lateral movement amplitudes can be effectively controlled, and different tower falling working conditions can be simulated. The support tower device also has the characteristics of simple structure, easiness in installation and suitability for various power transmission tower types; and the weak tower collapse working condition simulation in the wind tunnel can be efficiently and conveniently realized.

Description

technical field [0001] The invention relates to the technical field of wind resistance of transmission lines, in particular to a support tower device and method for simulating the collapse of a transmission tower in a wind tunnel test. Background technique [0002] The power system is an important part of a large-scale lifeline system, which presents nonlinear, high-dimensional, time-varying, and multi-layer dynamic characteristics. Its safety issues have always been paid attention to, and once a problem occurs, it will cause incalculable losses. Due to the frequent natural disasters in our country and the frequent accidents of wind-induced tower collapse on transmission lines, key research is needed. On the one hand, as an important supporting structure of transmission lines, transmission line towers are a typical wind-sensitive structure. Its wind resistance performance determines whether the transmission system can operate safely and reliably under strong winds; on the o...
