| 摘 要： | 作为暴露在自然环境中的风力发电机,不可避免地会受到雷电的影响,造成经济损失.因此,如何设计风电机组的防雷接地,是垂直轴风机需要考虑的重要问题之一.常规的深埋接地电阻和使用降阻剂来降低接地电阻的办法,需要庞大的费用支出.文中针对垂直轴风机这种新型风机形式进行了防雷接地设计,并进行了后续测量验证.研究结果表明,土壤电阻率在防雷接地设计中起关键作用,在进行地锚点选址时,应首先测量风机周围土壤的电阻率,选择电阻率偏低的位置作为地锚点,以便达到节省费用,降低接地电阻的目的.

| Abstract: | Wind turbines will be inevitably influenced by thunder because of working in natural environment,which causes economic loss.So how to design wind turbine's grounding for lightning is one of the main problems that should be considered in the design of vertical axis fan.The common method that uses deep-buried grounding resistance or resistance-reducing agent needs great economic costs.It may prove that soil resistance rate plays an important role in the wind turbine lightning-proof earthing design through the... |
