碳粉污染对风电叶片防雷性能影响的研究
Research of the influence of milled carbon fiber pollution on lightning protection of wind turbine blades
摘要
Abstract
In order to analyze the influence of milled carbon fiber pollution on lightning protection of GFRP,simulation analysis of electrostatic field based on FEM was established.Furthermore,high volt lightning tests were implemented with GFRP sample(0.5wt%milled carbon fiber).The results showed that the GFRP skin/PVC core material area and the pure skin area did not undergo breakdown in the high volt lightning tests.In the experiment,multipleting flashovers of milled carbon fibers were observed at the shallow surface of the fiberglass.The comparative analysis between numerical simulation and experimental results shows that the phenomenon is consistent with the conclusion in the simulation results that induced flashover may occur when the milled carbon fiber depth is less than 0.3 mm,and cannot occur at greater depths.关键词
