摘要:
公铁两用大桥的高压电力电缆接地方式直接影响其运行安全性和可靠性,电缆应单独设立接地系统或与铁路综合接地系统中的贯通地线相连,共用桥墩接地体。本文以福平铁路工程为例,研究了桥上电力电缆的接地方式。通过理论分析与模拟仿真,探讨了电缆接地与铁路综合接地系统共用的可行性。研究表明,合理设计接地系统能够有效控制短路电流,保证系统的安全性和可靠性。
Abstract:
The grounding method of high-voltage power cables of road-rail bridges directly affects their operational safety and reliability. The cables should either have a separate grounding system or be connected to the through earth wire within the integrated grounding system of the railway, sharing the grounding bodies of the bridge piers. Taking Fuzhou-Pingtan Railway Project as an example, this paper studied the grounding methods for power cables on the bridge. Through theoretical analysis and simulation, the feasibility of sharing the grounding system between the cable grounding and the integrated grounding system of the railway was explored. The research indicates that a reasonably designed grounding system can effectively control short-circuit currents, ensuring the safety and reliability of the system.
