Description

technical field [0001] The invention relates to a pole aging experiment device, in particular to a composite material pole multi-factor accelerated aging experiment device. Background technique [0002] With the rapid development of new materials, composite poles have emerged as the times require, which can solve the problems of traditional poles such as high mass, difficulties in transportation, installation and maintenance, and high flashover accident rate, and have attracted wide attention. In order to ensure the safe and long-term operation of composite poles, the weather aging performance test of composite poles used outdoors must be carried out. [0003] At present, for the aging experiment of composite poles, generally only one or two external conditions are simulated for aging behavior experiments. Although this kind of aging experiment can test the performance of composite poles to a certain extent, composite materials used outdoors When the pole is in actual opera...

Problems solved by technology

Specifically, in the natural environment, composite poles will face erosion from various external factors for a long time during operation. The more serious factors include high humidity in the atmosphere, alternating high and low temperatures, ultraviolet radiation, ozone and acid rain, etc. With the increase of time, the aging of the composite pole shaft will continue; at the same time, the wind deflection and galloping of the wire will also make the composite pole shaft in a swing state for a long time, which will cause the composite pole Stress relaxation fatigue aging; In addition, the strong electromagnetic field around the high-voltage wire will induce the polarization tendency of the polar groups in the material, which will affect the stability of the material and accelerate the aging of the material

[0004] Therefore, the existing aging experiments cannot comprehensively test the performance of composite poles, which brings safety hazards to the subsequent use of composite poles
