摘要:
［目的］城市轨道交通列车受电弓在接触网绝缘锚段关节范围停车造成的接触线熔断故障频繁发生，为避免此类故障，提高接触网安全服役性能，有必要开展接触网绝缘锚段关节停车防熔断措施研究。［方法］分析列车受电弓停在接触网绝缘锚段关节熔断接触线的原因，并提出改进措施。调研我国目前接触网绝缘锚段关节采用的管理措施，对绝缘锚段关节设置禁停标、采用负荷开关柜、采用分段绝缘器、采用带中性无电区段绝缘锚段关节、采用防熔断装置系统等多种解决方案进行技术经济综合比较分析，提出可避免此类故障，同时减少对行车组织能效影响的最优解决方案。［结果及结论］器件式分段绝缘器方案可实施性较好，配合设置禁停标，能够降低断线风险，建议新建线路采用器件式分段绝缘器。防熔断装置系统无需调整接触网系统现有的分段结构，仅增加轨旁设备，对既有线施工改造影响较小，建议既有线路采用防熔断装置系统。
Abstracts:
［Objective］The contact wire fusing failures frequently occur when pantographs of urban rail transit trains stop within the insulated overlap section of the catenary system. To prevent such failures and improve the safe service performance of the catenary system, it is necessary to conduct research on anti-fusing measures for trains stopping within insulated overlap sections. ［Method］The causes of contact wire fusing when train pantographs stop within insulated overlap sections are analyzed, and improvement measures are proposed. By investigating current management measures for insulated overlap sections in China, a comprehensive technical and economic comparative analysis is conducted on various solutions, including setting no-stop signs at insulated overlap sections, using load switch cabinets, employing sectional insulators, adopting insulated overlap sections with neutral dead zones, and implementing anti-fusing device systems. The optimal solution that can avoid such failures while minimizing the impact on the energy efficiency of train operation is proposed. ［Result & Conclusion］The sectional insulator solution demonstrates good feasibility in implementation. When combined with no-stop signs, it can effectively reduce the risk of wire breakage. It is recommended that sectional insulators be adopted for newly constructed lines. The anti-fusing device system does not require adjusting the existing sectional structure of the catenary system and only involves adding the trackside equipment, featuring minimal impact on the renovation of existing lines. Therefore, it is recommended that the anti-fusing device system be adopted for existing lines.
