室外长距离照明配电接地型式及电击防护研究

Research on Grounding Type and Protection against Electric Shock for Outdoor Long Distance Lighting Distribution

通过对室外不具备等电位联结条件的道路及景观照明设施电击事故的调查,得出应按潮湿环境要求对室外照明设施进行电击防护设计;同时为了使接地故障电压在安全限值以内,对室外景观及道路照明采用不同接地型式的优点和缺陷进行定性和定量地剖析比较,给出了满足电击防护安全要求的接地型式及相关其他安全防护措施。

Based on the investigation of electric shock accidents of lighting facilities for outdoor road and landscape without equipotential bonding conditions,it is concluded that protection against electric shock design should be carried out for outdoor lighting facilities according to the requirements of humid environment.At the same time,in order to make the ground fault voltage within the safety limit,the advantages and defects of different ground types used in outdoor landscape and road lighting are qualitatively and quantitatively analyzed and compared,while the grounding type that meets the safety requirements of electric shock protection and other relevant safety protection measures are provided.
