摘要
依据相关标准对港口设备防雷及接地的具体要求,设计了一套完整的抓斗卸船机防雷及接地系统方案。基于对防雷分区的分析,结合卸船机自身机械结构及内部配电网络的特点,方案分别从外部防雷和内部防雷两个方面考虑,为设备提供了全面、有效的防雷措施。
According to the specific requirements of relevant standards for lightning protection and grounding of port equipment,a complete set of lightning protection and grounding system scheme for grab ship unloader is developed.Based on the analysis of lightning protection zones and the characteristics of the mechanical structure of ship unloader and internal power distribution network,the scheme provides comprehensive and effective lightning protection measures for the equipment from two aspects of external lightning protection and internal lightning protection.
