Abstract

The invention discloses a wind excitation vibration wear simulation test device for a composite insulated cross arm, which comprises a swing end driving mechanism, a sliding connecting rod and a composite insulated cross arm simulation assembly which are arranged on a combined rack according to a design position. The swing end driving mechanism is connected with the sliding connecting rod through a centering slider-crank mechanism; the sliding connecting rod is connected to the bottom of the composite insulated cross arm simulation assembly, the swing end driving mechanism drives the sliding connecting rod to move horizontally through the centering type crank sliding block mechanism, and the sliding connecting rod drives the composite insulated cross arm simulation assembly to swing back and forth. In the swinging process, a measuring device on the composite insulated cross arm simulation assembly monitors in real time and transmits data to a computer, and corresponding monitoring data are obtained. A test platform provided by the invention is simple in structure and convenient to use, and can simulate low-frequency large-amplitude swing and high-frequency low-amplitude aeolian vibration of a lead in a distribution line, thereby providing convenience for research on wind-excited vibration wear characteristics of suspension string fittings.

Description

technical field

[0001] The invention relates to the technical field of composite insulating cross-arm aging characteristics and state evaluation research, in particular to a composite insulating cross-arm wind-excited vibration wear simulation test device. Background technique

[0002] Composite insulating cross arm is a new material cross arm, small in size, light in weight, high in mechanical strength and superior in electrical performance. It has the advantages of corrosion resistance, anti-aging, reduced line maintenance costs, reduced transportation and assembly costs, improved insulation level of distribution lines, etc., and well solved the problem of small reserved corridor width. At present, the composite cross-arm is showing a rapid development trend in our country, and has a wide application prospect in the future. In order to optimize the overall performance of the new composite cross-arm, and to be able to run on the net for a long time, it is necessary to cons...
