近年来,随着厦门机场内及周边的建设项目密集进行,开挖作业施工项目多,对地下管线构成威胁。施工作业等外力损坏电缆线路成为影响机场电网安全可靠供电的重要原因。加强地下管线的保护,防止外力损坏,上升为保障厦门机场供电系统安全的重要环节。本文结合笔者工作实践,介绍三个保护电缆线路防止外力损坏的案例,并总结相应措施。1供电系统概况厦门机场供电系统有两个10 kV进线电源总站
In recent years, as construction projects in and around Xiamen Airport have been intensively carried out, there are many construction projects under excavation, posing a threat to underground pipelines. Construction operations and other external damage to the cable line has become an important reason affecting the safe and reliable power supply of the airport power grid. Strengthen the protection of underground pipelines to prevent damage to external forces, rising to protect the safety of Xiamen Airport Power System an important part. This article combines the author’s work practice, introduces three cases of protection of cable lines to prevent damage to external force, and summarizes the corresponding measures. 1 Power Supply System Overview Xiamen Airport Power Supply System has two 10 kV incoming power terminal
